A better way to refresh data

Hey everyone, I'm creating a Flex/ColdFusion app. and I've
been working with CFCs and RemoteObjects. I know that when you want
to refresh data you have to call the CFC with the RemoteObject
every time (after the creationComplete is called I use addedToStage
and removedFromStage to re-call the CFC). Is there a better way to
refresh my data or "re-initialize" the component?
Also, does anyone know the proper way to log someone out
using ColdFusion and Flex? I pass the cflogout method in my CFC and
in Flex I return the user to the login page and "reset" my objects
I use to store user data, but after logging in as a different user
the previous user's info is still present. So I've resorted to
reloading the URL to clear the application of all data. Any tips?
Thanks,
PJ

I don't really get what you mean with "re-initialize the
component"?
Here you can learn about login and logout in ColdFusion.

Is there any better way to refresh?

Hello
I would like to know if anyone here has a better solution for refreshing components like JPanels. I'm developing an application which uses slow algorithms to draw the points on them. It would be absurd to call these methods again to simply refresh these components (ex: when the user minimizes or resizes the component), just as absurd as it would be to put the slow algorithm code in the paint(Graphics g) method.
The solution I'm using now is to save the coordinates and attributes of the points the program needs to draw in an array or some other data structure, so that the program can easily call a refresh method (which draws the points from the information store in these arrays).
But, since I'm using many (slow) algorithms, and since each plot has it's own particularities, I end up creating big refresh methods, even creating classes specifically to refresh components!
I was wondering if it would be possible to simply copy the image of a component in a given time, so that I could just repaint it on the component whenever it's necessary (i.e, when the component listeners called it). Is it possible?

I think want you're wanting to do is just a simple double-buffering?
So, the first time your component is asked to paint itself (you should override paintComponent() rather than paint(), by the way), do this:   private BufferedImage image = null;
   public void paintComponent(Graphics g) {
      if (image == null)
         image = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB);
         Graphics imageG = image.createGraphics();
         // TODO: paint your component onto 'imageG'
      g.drawImage(imageG, 0, 0, null);
   }You may also want to reset 'image' to null if the component changes sizes.

Best way to refresh page after returning from task flow?

Hello -
(Using jdev 11g release 1)
What is the best way to refresh data in a page after navigating to and returning from a task flow with an isolated data control scope where that data is changed and commited to the database?
I have 2 bounded task flows: list-records-tf and edit-record-tf
Both use page fragments
list-records-tf has a list.jsff fragment and a task flow call to edit-record-tf
The list.jsff page has a table of records that a user can click on and a button which, when pressed, will pass control to the edit-record-tf call. (There are also set property listeners on the button to set values in the request that are used as parameters to edit-record-tf.)
The edit-record-tf always begins a new transaction and does not share data controls with the calling task flow. It consists of an application module call to set up the model according to the parameters passed in (edit record X or create new record Y or...etc.), a page fragment with a form to allow users to edit the record, and 2 different task flow returns for saving/cancelling the transaction.
Back to the question - when I change a record in the edit page, the changes do not show up on the list page until I requery the data set. What is the best way to get the list page to refresh itself automatically upon return from the edit-record-tf?
(If I ran the edit task flow in a popup dialog I could just use the return listener on the command component that launched the popup. But I don't want to run this in a dialog.)
Thank you for reading my question.

What if you have the bean which has refresh method as TF param? Call that method after you save the data. or use contextual event.

CR 2008/VS 2005/Winform : HOW TO REFRESH DATA ONLY ?

Hi,
I display a report in a CrystalReportViewer (Windows Form).
This report have NO Saved data, use some parameters, use a formula, and connect to a SQL Server via OLE DB.
I would like to REFRESH THE REPORT after some data has been modified in the Database. (just the DATA in the report, NOT the parameters, NOT their values, and NOT the formula).
PROBLEM : this SIMPLE TASK seems to be IMPOSSIBLE to do !!! (I can't beleive this !)
If I call Refresh() or ReportRefresh(), in the Viewer or in the ReportDocument, the formula AND the report Parameters have no more effects.
"ReuseParameterValuesOnRefresh = true " : DON'T WORK !!!
QUESTION : Is there a way to refresh DATA in a report without completely reload the entire report file & params & formulas & Data & ... ???
Thanks a lot for your help.
Steph

I have had a similar issues with report parameters.
The solution for me was to set the parameter value in the RefreshReport event of the ReportDocument not the crystalReportViewer.

EXIF Dates - how to add/change using exiv2 . . . is there a better way?

Hi, everyone!
INTRO: I'm new to Lightroom. I've gone through a few books and lots of tutorial courses on lynda and youtube, so I feel quite comfortable with LR 5's import process. This post and question is a pre-import/organizational issue.
I have more than 30,000 old, digitized (scanned) photos dating back to the 1950s. Obviously, most of were taken with old, analog cameras. These are now organized into folders by date.
GOAL: I want to import these photos into LR and be able to find them by metadata dates (Capture Date & Time).
PROBLEM: Obviously, old scanned (or even more recent manipulated) photos often don't have the correct EXIF creation date info. Even worse, many (or most) of these old images don't even have an EXIF date field!
WHAT I'VE LEARNED: Using exiv2 filename or evix2 -pt filename immediately shows whether there is or is not date info for the photo. If there isn't, exiv2 -pt filename shows nothing. If there is an EXIF date field, it will be shown.
For all these images with no date field, if I import them into Lightroom, there of course is no date info that shows up in the Metadata panel (under Default or EXIF), nor can you change the date (because the field isn't even there).
If exiv2 -pt filename DOES show the Exif.Image.DateTime field, then in Lightroom, you will see the Capture Time and Capture Date fields, and you will see an icon to the right of those dates that allows you to change that date.
If exiv2 -pt filename DOES NOT show this Exif.Image.DateTime field, you can ADD this field by using the command line:
exiv2 -M"set Exif.Image.DateTime Ascii 1965:01:25 15:45:00" filename (or whatever your date/time is).
Now if you import this image into LR, you will find the Capture Time and Capture Date fields under the Metadata > Default panel...AND you can edit them if needed. That is, the above exiv2 -M command added the EXIF date field that LR needs in order to search by date.
WHAT'S MY POINT, AND WHAT'S MY QUESTION? I have no problem using exiv2 to add/change an EXIF creation DateTime field one folder at a time prior to importing them into LR. This will enable me to search on those date fields**.
My question is this: Is there an easier method?
Surely there must be tens (hundreds?) of thousands of "older" photographers like myself who have troves of old photos that have incorrect EXIF creation date fields, or missing the date field entirely (in which case, as I stated above, cannot be added/edited using LR, PS, FileMultiTool, Graphic Converter, etc.).
I realize that I could look at images based on the folder names or file names, or I could enter dates into tags, but such methods of finding images are not nearly as convenient as using Metadata. Therefore, if I know that an image was taken in June 1962, then I'd like the EXIF metadata to have this info so that I can search on it. To have no EXIF date field or to have a date field that is incorrect is useless.
I'D LOVE YOUR COMMENTS! If there is an easier or better way, I'd love for you to help! There are so many experienced photographers on this forum, and more than likely many of them have old photos with incorrect or missing EXIF date fields that they've brought into LR.
THANKS! I'll really appreciate any and all help you can offer.
David
** there are other EXIF date fields that can be changed using exiv2: Exif.Photo.DateTimeOriginal, Exif.Photo.DateTimeDigitized, etc. But the principal date that LR uses to search for files is the one described above.
P.S. I've also tried jhead -ds1965:01:25 filename (or whatever your date is) to change the date. This works ONLY IF there is already an EXIF date field present. If not, jhead will report an error and not create one. exiv2 -M will create the field.

John,
Thanks very much for your help! I had tried the plugin, exiv2, exiftool, and LR's Metadata menu option only on a single photo.
You are 100% correct about LR's menu option assigning different times! Thank you for pointing this out.
When I set the date and time for about 10 photos, LR's menu option assigned (seemingly random!) times to all of them. Why would LR do this? I can perhaps see offsetting each photo by 1 second (00, 01, 02,...), but simply assigning random times makes no sense at all. At least in the tests I just did, LR didn't shift the time by the same amount, but assigned totally (random?) times to every photo.
Another problem that I found with the LR menu item is that it failed to change the date/time at all for several of the images I selected! The Capture Time To Exif plugin, exiv2, and exiftool had no problem at all with the same photos.
I also looked at the ExifMeta by Rob Cole that you mentioned. It looks very powerful (and is free), but much more complex than what I need at this point.
Therefore, I purchased the Capture Time To Exif plugin, and it works great on multiple photos.
I now have good methods to change the date for multiple images:
1. Prior to import: exiv2 or exiftool
2. After import: John's Capture Time To Exif plugin
Thank you again for your help!
This brings me one step closer to importing my photos in a logical method.

Catalog settings and meta data is there a better way.

HI
I have adobe cs4 and light room 2.2 I do my editing in LR cropping exposure web galleries and so on on, thats all well and good but any modifications i make will not show up in the bridge unless i go into light room and apply save meta data to files. I have about 400 light room catalogs as I store the catalog in the folder that contains the original image. Is there a way to have light room automatically apply meta data changes to each catalog in stead of going to catalog settings or saving the meta data to the file. its a pain in the *** to have to go into a catalog and apply all those settings if i want to do some editing in the bridge

> ...is there a better way ...
Might I humbly suggest that your multiple (400!!) catalog strategy is flawed? You have defeated the benefits of having a single database. (And those that argue a database is bad concept and a possible single point of failure are ... well ... simply wrong.)
Lr can automatically write XMP data so that Bridge can read it. But the reverse is not true. Any changes that Bridge/ACR make will have to be imported into Lr with manually initiation.
The point and beauty of Lr is that you make the majority of adjustments in Lr. It's possible to make adjustments in Bridge and have them imported into Lr but as you discovered it is not automatic. And your workflow choice makes it doubly (or 400 times) more troublesome.

Time difference by date by time range - a better way?

Someone suggested this is a better place for my question:
Hi
I need to display the difference in time - every day for different time ranges,
Example 1-2 pm, 4-5 pm, 7-8 pm. And I need the time difference in 2 dates in the past week for each of these ranges everyday.
example
Date Diff Range
01/01/2007 00:01 1-2pm
01/02/2007 00:03
01/03/2007 00:10
01/04/2007 00:05
01/05/2007 00:23
01/01/2007 00:10 4-5pm
01/02/2007 00:13
01/03/2007 00:11
01/04/2007 00:15
01/05/2007 00:23
01/01/2007 01:10 7-8pm
01/02/2007 00:13
01/03/2007 00:10
01/04/2007 00:11
01/05/2007 00:21
One way to achieve this is to have multiple unions for each day and each time range.
Example:
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
union
select
from
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
This will give me the required information for only one day - and that is for sysdate-5.
I will have same nyumber of unions for each day.
Is there a better way to accomplish the same?
Any help appreciated.
Thx!

Hi
Sorry for the late response but better late than never:::
I have gotten the answer of getting data for previous 5 days. I have changed the time between statement and is given below(*).
Here is a reply to all the questions you had asked in response to my questions.
What data you have? What parameters are you going to input?
I have already given sample data in my post.
There are no input parameters.
You are talking about the difference - between what is this difference?
Difference is the difference between 2 timestamp datatypes in 2 different tables (as you may see in the query)
The field diff - is it varchar2 like '1-2 pm' or what?
I didnt understand your question. What do you get when you subtract two timestamp datatypes - that should be the datatype - if I have understood your question. Not sure if thats what you asked.
But IMHO it's impossible to get such a result, of course, if dt_tm in the query is the same as Date in the result!
The time components in the queries are different. If you see:
1st Query:...
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
2nd Query:....
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
3rd Query:
where dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
First should be between 1 and 2 pm for sysdate-5.
I need starting previous 5 days till sysdate.
Second is between 4 and 5 pm again for sysdate-5.
I need starting previous 5 days till sysdate.
Same with 3rd.
My final query is something like this:
select t1.dt_tm, count(t1.id), '1 - 3 am' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 13:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 14:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
union
select t1.dt_tm, count(t1.id), '4 - 5 pm' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 16:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 17:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
union
select t1.dt_tm, count(t1.id), '7 -8 pm' as period
from table1 t1, table2 t2
where t1.id = t2.id
and dt_tm between
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 19:00','mm/dd/yyyy hh24:mi:ss')and
to_date(to_char((sysdate-5),'mm/dd/yyyy')||' 20:00','mm/dd/yyyy hh24:mi:ss')
group by t1.dt_tm
I need for the last 5 days and what i can think of is have 5 different queries for past 5 days and 3 queries per day for the 3 different time periods. This would mean 15 queries. Was wondering if there is a better way to achieve the same?
Any help appreciated.
Thx!

Efficient or Better Ways for Data Declaration

Hi Guys,
Basically I've always programmed much the same way for a pretty long time now. Lately I've been asking myself the question - "how can i start improving on my tried and trusted ways".(oftern a linear programming approach). As part of this I'm examining ways to declare data better within in programs and to adopt a neat way to do so.
This may seem pretty trivial but the first question I want to ask is how to declare data better
e.g. I need to declare constants - each constant corresponds to a rule number; 1, 2,3,4,5,6 - 23 etc.
Instead of declaring the following line 23 times - is there a better way to declare in such a way.
Constants: c_rule_1 type c value '1' ,
                c_rule_2 type c value '2',
                etc etc etc
Your thoughts are greatly appreciated.
Thanks.
DK

Hi,
With my knowledge, data declarations for all constants with DATA comamnd itself is good practise in point of performance. Alternative is dynamic creation of variables. But it consumes more time and is not good to practise. Instead of crating individual parameters for each constant, you could create a structure and add all constants as fields as follows:
constants: begin of con,
                   1 type c value '1',
                   2 type c value '2',
                end of con.

A better way to run a 7 day report?

Using Crystal Reports 11
I am hoping there is a better way of running a seven day report that i have to run weekly
In the report i have it set when refreshing the document, the "Prompt for new parameter values" comes up and there is a date field for start and end
This is how i did it
I made a formula called "Date" this comes from the closed date of our accounts
I made a Parameter Field "Start Date" with the TYPE field is "Date"
I made a Parameter Field "End Date" with the TYPE field is "Date"
I made a Select Expert Using data from the "ClosedDate" in the first drop down I picked "Formula" and used this as the formula
{WH_ACCTCOMMON.CLOSEDATE} in {?Start Date} to {?End Date}
Two things
1. Is there a way to have "Prompt for new parameters values" as the default checked off box when clicking "Refresh"?
2. Is there a way to only enter a start date and the refresh would just run 7 days without entering a end date?

Hi,
Here's a suggestion for question 1:
When you preview the report for 1st time there is no prompt window that asks you to select whether you wish to 'Use current values' or 'Prompt for new values'.
If the Preview window is open and you hit refresh again, this is when you get the pop-up with the above options. If you close the Preview window and refresh again, you would not get a pop-up and it will show the Prompt window instead.
For question 1, you can follow Alun's sugestions.

Cannot refresh data in Excel Services with SQL Azure databases

I am using Excel Services on a SharePoint Online.
I get my data from a SQL Azure. When i create my Excel repor with Excel 2013 pro I have no problem. So I upload my file on my Sharepoint and try to refresh data.
Connexion : Power Query - RPT_Event_ByEventType
Erreur : Erreur sur site (OnPremise) : Sorry, the data source for this data connection isn't registered for Power BI. Ask your Power BI
admin to register the data source in the Power BI admin center.
I do not understad why I get that error because my data source is on Azure why It told me "OnPremise" ?

hi,
>> this button of excel gets just address of web and have button for import it
i test it by rest API project , but doesn't work, do you know how it is work?
Do you mean that you don't know how to get the table? You may input the site address into the address box, and then click go button nearby, select the table you want to import into the Excel. Then click import button.That also works for rest API,
and your rest API should get the data that you want
By the way, this is the forum for discussions about Excel develop(VBA ,customization), better to go to TechNet forum for Excel for Excel features question, so that you could get more professional help.

How do I show/refresh data from an Access Web App in an Excel spreadsheet saved in a Document Library on Sharepoint 2013 online

I have an Access 2013 Web App in my Sharepoint 2013 online website. It contains a query to report on its data (several, actually, but let's keep it simple). I want to connect an Excel spreadsheet to the query, visualise the data in pivot tables/graphs/whatever,
save the spreadsheet in a Document Library, and let other team site Sharepoint users open the spreadsheet (preferably in Excel online, but with Excel client if it has to be) and see/copy the data, refreshed with the latest information from the Access Web App.
Simple, surely!
The way I'm doing it at the moment is to create an ODC file to connect to the cloud-based Access 2013 database, save that ODC in a Data Connection Library in the SP site, and use the saved ODC file as data source in the Excel spreadsheet. This works and
successfully keeps everything 'in the cloud' but I can't get it to refresh in Excel Online, and if I open the spreadsheet in Excel Client I have to enter the database password every time to refresh it. I don't really want to issue this password to everyone
who might want to view the data. There must be a better way than this ODC method, I suspect.
Googlings on this have led down various blind alleys - Excel Services, PowerPivots, Web Parts - but I'm stuck on which to follow through. Please, someone, point me to an article/book/website that explains how to do this step-by-step in simple language..
thanks
Jonathan

I don't see any quick way of achieving it - at least there's no such functionality exists in SharePoint. All you can do, develop an event receiver that will update the fields in the list item once the excel file is added/updated. You can use OpenXml API
to manipulate the excel file.
Thanks,

Report prints Saved Data not Refreshed Data

We were running VS 2005 and using the Basic CR 2005 Basic that comes with it. We upgraded to use CR 2008 and found MANY issues after we went live in production that were apparent in the development. This has caused a lot of stress with us as well as our users. Iu2019ll summarize everything we found, possible workarounds and the open issues including the Printing/Loading of Saved Data.
First, it was reported that printing changed. It turns out when PrintMode = u2018PDFu2019 (default setting) it now asks after you choose u2018EXPORTu2019 (use to be u2018OKu2019) that it asks to Open or Save the Adobe. When our customers were running 20 some reports at a time and we had hundreds of users, this became a nuisance for the heavy reporting users and a training issue in general for us. With research, I found that we can change the PrintMode to be u2018ActiveXu2019. This was much better when we were testing. However, in Production it became a nightmare. If the user is on a Domain that disallows itu2019s user from installing software or if the user has tight security settings, this became a nightmare.
The second thing reported was that it was exporting to the wrong format. It was exporting into RPT format. It turns out with CR2008, it automatically defaults to RPT and the new pop-up, doesnu2019t isnu2019t clear to the user they even have a choice (the pop-up is much prettier, but it doesnu2019t look like a dropdown anymore). In addition, they reported it was taking twice as long to export (we think it was related to export file type now). With CR2005 Basic, it would have no default selection and if the user didnu2019t pick one, it would remind them they need to pick one. After much research, I found there is no way to customize the operation of the export without writing my own export. My users 90% of the time want to export to PDF and Excel the rest of the time. Since we arenu2019t using a CR Server like product, they NEVER will do RPT. There is no way with CR2008 to limit this list or to default the File Format. So now, if they forget to select the type, they get the wrong file format instead of being reminded to select one. Since the new pop-upu2019s dropdown selection isnu2019t easily apparent, this was a BIG issue for us. Since I have close to 300 reports on 7 websites, this will be a lot of work for me to write my own code and change all the ASPX page to use my own control.
The third thing reported was that the default name on Exporting was changed. Export uses the ID property of the Crystal Report Viewer as the default name of a file on export. When it replaced the viewer on all our pages, it set the ID to CrystalReportViewer1 instead of preserving the original ID. We now have to go back and change them to what we wanted manually. BEAWRE of this! For our power users who wanted to export 40 reports they now have type the name in manually on all of them. What took minutes now takes over an hour for them to do, until we can fix all the pages.
Now it was reported that some reports are showing OLD data. It turns out there shows Saved Data from design time. In our site, we have a parameter page which getu2019s user selected parameters, save to a session and then load the report page using the session variables, and then redirect them to the report page which on page load we set the reports parameters. We use the CrystalReportSource using ODBC. The report has all the connection information. Well if the user happens to select the same parameters I used at design time, it wonu2019t pull the data from the database. They see our test data instead which is garbage. If they select different parameters, display the report and then go back and select the original parameters, they will get the correct data. This can be catastrophic for us! So I added at the beginning of the Page Load before setting parameters the following:
     If Not Page.IsPostBack Then
            CRSServiceAlertsReport.ReportDocument.Refresh()
     End If
This seemed to work. A pain to add on every report page though when it wasnu2019t necessary before. But then I just got called this morning and they say when they print, it prited the OLD data. It seems the refresh pulled new data and updated the display in the viewer but the ActiveX print still used the original Saved Data! I couldnu2019t find a solution for this. I found switching PrintMode back to u2018Pdfu2019 worked but now I have the extra click issue again, which I described above. I tried setting the reports u2018Discard Saved Datau2019 option but it still had the data!
In the end, had I known about all these issues I would have NEVER upgraded to CR2008. Iu2019m still looking for help on getting by the following:
u2022     Stop using Saved Data at runtime (either on Display or Print)
u2022     Getting the PrintMode=u2019Pdfu2019 to just pull up Adobe in Open mode without prompting the user.
u2022     Remove File Type options from Export
u2022     Set the default File Type options to nothing or something I want.
Another nice feature to have would be the ActiveX control for printing to be part of the .NET Framework so users donu2019t need to download it. Come on BO is a big company Iu2019m sure they can work with MS. 

What is that method to clear Saved Data; I looked and couldn't find it. I never had to call one in the prior version of CR 2005 Basic in .Net. With the .NET controls, it always refreshed the data before. This is a change in behavior for me.
As for the Print using Adobe, with CR2005 Basic, it didn't prompt the user to Open or Save before. This is new behavior. It used to just open the report in Adobe in memory before without this specific prompt (it did have the first prompt for All or specific pages, but it would just open after that). This is a change in behavior from prior versions and it has caused me several issues.
Many users don't like change and I didn't know to communicate this to them. They were taken by surprise. We'll learn to live it I guess, but I would ask you just to consider, why have an option to "Save" to PDF when you choose to print? I would think you would use Export if you want to save. It would never hurt to add an option to allow alternatives either.
As for including with .NET Framework, it was just an idea. I know how hard it can be working with third parties. However, given that CR Basic comes with it, I thought it may be possible to work with them. The better the integration the better the product is for the developers. I was thinking the button could call JavaScript/Java to print instead of an ActiveX, or some other method. Since I donu2019t know how the Control works, I couldnu2019t say. It just would be nice. I had a smiley face after that request, it didn't come out right when I saved the post.
I still don't understand why .Refresh will update the data in the viewer but printing using the ActiveX Control will still print the saved data instead of refreshed data. Since I never used this in the prior version I don't know what it would of done or not, but it just doesn't seem right it shows one set of data, and prints another.
In addition, why the designer still saves data with the report when you state not to, I think may be a problem still.

Report auto-refreshes data in the background

Post Author: tpoland

I ran a very large report that does some formula calculations based on a sub-report, in all it takes about 30 minutes to process. After it finished running I minimized Crystal and went on to work on some other things. After about 5 minutes my system started crawling and when I looked at the CPU crw32.exe (Crystal XI) was using between 90 and 99% of the available CPU. When I finally was able to maximize Crystal again I saw that it was refreshing the data in the report. Is there a setting that I can use to prevent Crystal from doing this?
Thanks,

Since you talked more about your requirement.
My suggestion is still not to use subreport.
And the better way is try to let the subreport result into a view.
I guess your report should like this:
          PH
          Loc
          Amount
          Rank
          GH
          USA
          D
          CA
          10
          3
          D
          FL
          30
          1
          D
          PA
          20
          2
The "Rank" is what you get from formula, right?
You can prepare a view with a calculated field "rank" and joined the original
table.

Refreshing data in tables from MySQL

hi guys,
im currently developing a banking application using Java and MySQL, and some encription methods, for a degree project in software engineering.
iv have tables displayed on a serperate tab panels.
im connecting to multiple databases.
what i want to know, is it possible to "refresh" the data when the application is running.
so, lets say i update someones records using the application, when i go to the details panel, containing the records, i want the application to re-display the data to its present form.
iv tried putting the "data call" method from the database as a function, and attatching that call function to a "refresh" button, but it doesnot re-display the information when the application is running.
although, when the application is closed and executed again the new data is displayed correctly.
any info appreciated.
heres a few screen shots for a better understanding of what im working on:

Thanks alot..

The easiest way to do this is to create a new TableModel with the refreshed data. Something like:
a) do SQL query
b) TableModel model = new TableModel(data from SQL query)
c) table.setModel( model );

Need help to get alternate or better way to write query

Hi,
I am on Oracle 11.2
DDL and sample data
create table tab1 -- 1 millions rows at any given time
id       number       not null,
ref_cd   varchar2(64) not null,
key      varchar2(44) not null,
ctrl_flg varchar2(1),
ins_date date
create table tab2 -- close to 100 million rows
id       number       not null,
ref_cd   varchar2(64) not null,
key      varchar2(44) not null,
ctrl_flg varchar2(1),
ins_date date,
upd_date date
insert into tab1 values (1,'ABCDEFG', 'XYZ','Y',sysdate);
insert into tab1 values (2,'XYZABC', 'DEF','Y',sysdate);
insert into tab1 values (3,'PORSTUVW', 'ABC','Y',sysdate);
insert into tab2 values (1,'ABCDEFG', 'WYZ','Y',sysdate);
insert into tab2 values (2,'tbVCCmphEbOEUWbxRKczvsgmzjhROXOwNkkdxWiPqDgPXtJhVl', 'ABLIOWNdj','Y',sysdate);
insert into tab2 values (3,'tbBCFkphEbOEUWbxATczvsgmzjhRQWOwNkkdxWiPqDgPXtJhVl', 'MQLIOWNdj','Y',sysdate);I need to get all rows from tab1 that does not match tab2 and any row from tab1 that matches ref_cd in tab2 but key is different.
Expected Query output
'ABCDEFG', 'WYZ'
'XYZABC',   'DEF'
'PORSTUVW', 'ABC'Existing Query
select
   ref_cd,
   key
from
    select
        ref_cd,
        key
    from
        tab1, tab2
    where
        tab1.ref_cd = tab2.ref_cd and
        tab1.key    <> tab2.key
    union
    select
        ref_cd,
        key
    from
        tab1
    where
        not exists
           select 1
           from
               tab2
           where
               tab2.ref_cd = tab1.ref_cd
    );I am sure there will be an alternate way to write this query in better way. Appreciate if any of you gurus suggest alternative solution.
Thanks in advance.

Thanks for posting the CREATE TABLE and INSERT statments. Remember why you go to all that trouble: so the people whop want to help you can re-create the problem and test their ideas. When you post statemets that don't work, it's just a waste of time.
None of the INSERT statements for tab2 work. Tab2 has 6 columns, but the INSERT statements only have 5 values.
Please test your code before you post it.
I need to get all rows from tab1 that does not match tab2 WHat does "match" mean in this case? Does it mean that tab1.ref_cd = tab2.ref_cd?
and any row from tab1 that matches ref_cd in tab2 but key is different.
Existing Query
select
ref_cd,
key
from
select
ref_cd,
key
from
tab1, tab2
where
tab1.ref_cd = tab2.ref_cd and
tab1.key    <> tab2.key
union
select
ref_cd,
key
from
tab1
where
not exists
select 1
from
tab2
where
tab2.ref_cd = tab1.ref_cd
Does that really work? In the first branch of the UNION, you're referencing a column called key, but both tables involved have columns called key. I would expect that to cause an error.
Please test your code before you post it.
Right before UNION, did you mean
tab1.key    != tab2.key? As you may have noticed, this site doesn't like to display the <> inequality operator. Always use the other (equivalent) inequality operator, !=, when posting here.
I am sure there will be an alternate way to write this query in better way. Appreciate if any of you gurus suggest alternative solution.Avoid UNION; it can be very inefficient.
Maybe you want something like this:
SELECT       tab1.ref_cd
,       tab1.key
FROM           tab1
LEFT OUTER JOIN tab2 ON tab2.ref_cd     = tab1.ref_cd
WHERE       tab2.ref_cd IS NULL
OR       tab2.key     != tab1.key
;
