Complex database display for Datagrid

Hi to all,
I am new to Flex (& Web GUI design).
I am trying (unsuccessfully) to develop a display that
monitors the condition of items at different locations in the form
of a datagrid.
The database system provided to me basically use a
"many-to-many" relationship to store the data:
1. Table Item: item_id
2. Table Appl: appl_id, location_name
3. Item-Appl Mapping Table: maps item_id to appl_id
Basically, 1 item is being monitored by several Appl at
different locations; while 1 Appl can also monitor multiple Items.
In my design, I have to continously query the database to
obtain the current condition of the Item, where I try to obtain the
following information:
Notification table: item_id, Appl_id, Time, Type
; where Type indicates the change in the Item (item_id)
condition at location (Appl_id).
Based on this query, i need to update the item status on the
Datagrid
The main issue here is:
1. How do I design the dataProvider for the dataGrid (Item vs
Location)
- I have to dynamically create the dataGrid Column since the
location can be dynamically changed/added/removed from the
database.
My dataGrid should look like this :
Item "A" "B" "C"
M X O O
N O O X
R O O O
"A","B", "C" are Location names; which are user-inputs &
I do not have any information about it beforehand. I have to obtain
this locations from the location_name in Appl Table.
The X,O indicates the condition of the Item.
Has anyone done something similar to this before & point
me to the right direction?
Many thanks,
Regards,
hy

Hi,
Very much thanks for the reply.
In my case, more than 1 Appl can monitor 1 item at same
location (which can be a big hierarchy of places:
A->AA->AAA).
E.g.: Appl #1 monitor Item M at Location A.AA & Appl #2
monitor Item M at Location A.AB. I need to display the overall
result for Location A (Location A.AA and A.AB)
This means that I need to store the result 1st somewhere in
my cache & then do some post-query processing to obtain my
final result.
What would be the best arrangement to store this data &
how can I set it as my dataProvider to the dataGrid?
Thank you very much.
Regards,
hy

Tooltip for datagrid's cells

I know how to create a tooltip for datagrid and/or its
columns. Is it possible to create a tooltip (or something similar)
for each cell? So whenever the mouse is over a certain cell, a tip
would be shown for that cell that depends on the value of the cell.
Similar functionality can often be seen in web-based database apps:
an Ajax query gets related data from a database on mouseOver.
My need and idea is to
- show a simple text list as a tooltip
- the text would be fetched from a database via a web service
- the fetch would be based on datagrid's (hidden) rowid and
each column's (hidden) column id (which are real database columns)
- the database structure is an n:m relation i.e. one
rowid+colid can refer to several items that are then used in the
tooltip
Use case: A number is displayed in the datagrid. The need is
to display 0-n references related to that specific figure (e.g.
book names, notes etc) in the tooltip. Next cell's tooltip would be
showing different references.
Anybody any ideas or suggestions? Thanks!

Hi,
Did you try creating a custom itemRenderer and handling the
mouse events for that item renderer component. There is also a
property called dataTipFunction, please check that too.
Hope this helps.

Export Release Build for datagrid [xml file doesnt show?]

SRC folder
          assets
                    icons
          db.xml (located within assets folder)
datagrid.mxml
default.css
I am able to load the database and it populates my "db.xml" with no issues, however when I export release build and run the app - the database displays but with no information? I noticed that the my "db.xml" was not exported as well.
It is set up correctly? or do I need to just drop my icons, db.xml within src folder and not seperate them?
thanks

When you export a release build, it takes all your MXML And ActionSCript files and turns them into a SWF without the extra debugging code. If you are not embedding the XML in the swf, then this is expected behavior.
In your project properties, under Flex Compiler you can try checking the "copy non-embedded files to output folder"; but I believe this is only for debugging purposes and not for exporting a release build.

Pause / Resume button combination not working when set to display for "rest of project"

Good day,
I have created a set of four objects on slide2 of my project
1. Smart Object rounded rectangle with text "(playing) - CLICK to Pause" [this is the graphic the user sees]
2. Smart Object rounded rectangle with text "(paused) - CLICK to Resume" [this is the graphic the user sees]
3. Smart Object rectangle, transparent, used as button, set to not display in project - btn_Resume
4. Smart Object rectangle, transparent, used as button - btn_Pause
A. Script assigned to btn_Pause hides btn_Pause and the "CLICK to Pause" graphic, shows the btn_Resume and "CLICK to Resume" graphic, and pauses the project by setting the system pause variable to 1
B. Script assigned to btn_Resume hides btn_Resume and the "CLICK to Resume" graphic, shows the btn_Pause and "CLICK to Pause" graphic, and resumes the project by setting the system resume variable to 1
C. All items are set to display from the beginning of slide2 for the "rest of project"
On slide 2, the buttons hide/show and pause/resume behaviors work correctly.
On slide 3, the correct initial button and graphic appears, and the click sound works when clicked, but no behaviors (show/hide/pause) occur until a good amount of time into the slide: you can click all you want for 20-30 seconds, but nothing works except the click sound. Eventually, the behavior will work.
On slides 4 and following, the correct initial button and graphic appears, and the click sound works when clicked, but no behaviors EVER work.
If the behaviors NEVER, EVER worked, I would keep looking for what I did not have set correctly, but the correct working on the slide where they are set, delayed behavior on the next, and no behavior on the remainder of slides following has me stumped.
Captivate version 6.0.1.240
Windows 7 OS
I hope I'm missing something obvious here, and I'm more than willing to face-palm if you tell me . Otherwise, I have not been able to find any setting that makes any difference. I would REALLY rather not duplicate the buttons and scripts on every page of the project. Given the blog posts I have seen saying this method should work just fine, I'm hoping there is a side quirk somewhere that I'm missing.
Thanks for any help you can give.

Without clouding with too much explanation, this technique arose out of a need to deal with (in a different project) objects that were grouped, and wanting to deal with the groups in as simple a way as possible, allow for easy swapping of group assets, and having a few buttons do multiple things. The idea of being able to have multiple interactive buttons stacked on top of each other while appearing for the rest of the project led to trying this simple construct before trying something more complex.
You are correct, that there is a simpler solution, which we ended up using because we were not able to get two interactive buttons stacked on top of each other while displayed for the rest of the project to work properly (although that is SUPPOSED to work, as far as I understand).
Here's what we ended up doing:
A) Two smartshapes used as messaging graphics
B) A single (one) interactive smartshape used as a button
C) A conditional action to pause/resume and show/hide the appropriate messaging graphics
D) All three objects (A&B) stacked, B on top.
E) All objects set to always appear on top, and to display for rest of project.
Our hypothesis, then, is that you are not able to stack interactive objects on top of each other and then display for the rest of the project.
If anyone has evidence to the contrary, we would, gladly, take a look.
Thanks for your interest Lilybiri, and for your input.
Best regards,
Hank

Creation of a database engine for mobile devices using j2me

am trying to develop a database engine for mobile devices.. it is to develop a miniature version of the DBMS that
can be deployed on a mobile phone..I have to develop my own code for performing tasks such a s creating a table,
inserting values into it, selecting from it etc..
I limited my self to develop the software so that it can perform 3 functionalities of create, insert,select..
I should be taking the details such as table name and its parameters from the user and then should be able to
create a suitable data structure for it(i tried to develop a class)...
Usage of RMS package helps me partially in this.. I did that and ll be doing that..
I got stuck while developing the code for creation of a table.. I am facing problems in creating a dynamic data
structure for a table and also to use such data structure else where in my project..
I need help in developing an algorithm for this..
I would be very grateful to u all if u help me out in developing the code for this project..

I'm sorry for the amount of time it took me to get back. Derby is an open source database written entirely in Java. I do not know if it can support resource constrained devices like MIDP compliant, but may work okay with CLDC.
But outside of Derby being a solution, let me give you a few ideas off the top of my head.
Set up a database server in a separate thread. This server will really be your controller for RMS access.
Since RMS is just a big sequential 'pipe' you will have to think of data as 'frames' - (starttable) (tableID) (tablename) (data) (tablename) (data).....(endtable).
When you need to write additional data, just append it to the end of the RMS object.
When you need to retrieve data, thing are more complex.
1. Read in all data, looking for your particular tableID. This may be made much easier using RMS filters - (I'm not sure, I've never used them)
2. Once start of table of interest is found, stick the data elements in either a java vector or array until you reach the table end identifier. I think vector will be a better choice - trust me. (I think its available in J2ME...)
3. Package this into a do while loop until the element you are searching for is read. If you need to do some sorts on the data or something else that requires the all the data to be present then you need all the data for that particular table. One thing will always be clear. The first data you grab will always be some start table identifier and the last data you grab will be an end table identifier. We just don't know which table because of how we put stuff in the RMS resource.
This provides you a few positives as well as negatives:
Positive:
1. Fast data writes, no need to search for a particular table before accessing it, nor do you need to search for an index in that table.
2. When looking for data, data may* be found without searching through the entire table. This is accomplished with RMS filters or logic test within the RMS read loop.
Negative:
1. Slow when all data of a table is needed (i.e. compute sums or averages of entries). The entire RMS database must be read to ensure all the entries are searched. An example of how this is a problem is as follows: You have 5000 entries in you RMS database resource and you are looking to compute the average of a value in some table. When you first wrote the data to the table, it was done sequentially and no other data for that table exist. But we can't tell if that's the case, so we have to read through all 5000 entries to make sure we looked for every piece of data.
Beacuse of this issue, this database structure, performance may be fine for 50K - 100K entries (depending on table element size), if the reading requirements don't force full data reads. Otherwise, 25K may be an upper limit.
I hope this helps.

1. I think i found out why the hide region is not working, whenever i search for something that is not in my database or does not satisfy my search criteria the results page is displaying all records in the database. However i don't know how to fix that. Can someone please help me?
2. Also i'm trying to find out how i would display ALL vehicles in my database either for rent or sale, i dont have a field in my database for "ALL" so i'm not sure where to start. Thanks in advance

Which BOBJ version do you use?
Which kind of data source are you retrieving data from?

Listing mysql database tables in DataGrid

Hi everyone,
I'm trying to Display all availible Tables of a Database in a DataGrid.
Rather than listing the data in the column, it lists them in the first row of the column sperated by comma.
Please, can someone tell me what i'm doing wrong there?
Thanks in Advance.
Mat
Code so far:
    <mx:DataGrid id="dgTableListRequest" x="75" y="60" dataProvider="{tableListRequest.lastResult.tablelist}" height="145">
        <mx:columns>
            <mx:DataGridColumn headerText="Tables" dataField="table"/>
        </mx:columns>
    </mx:DataGrid>
PHP:
$Query = "SHOW TABLES FROM vokabeln";
$Result = mysql_query( $Query );
$Return="<tablelist>";
while ($row = mysql_fetch_row($Result)) {
$Return.="<table>".$row[0]."</table>";
$Return.="</tablelist>";
print ($Return);

This should work:
<mx:DataGrid id="dgTableListRequest" x="75" y="60" dataProvider="{tableListRequest.lastResult.tablelist.table}" height="145">
        <mx:columns>
            <mx:DataGridColumn headerText="Tables" dataField="*"/>
        </mx:columns>
    </mx:DataGrid>

Database structure for a 5 star ratings system

This is something I've been asked to look at creating. At the moment the site has a database back end storing details of a few hundred holiday properties. So that part is already set up.
So I'm familiar enough with databases etc, but less so the formulas and any additional database structure for any voting.
It would be pretty simple, ie visitors could vote 1, 2, 3 4, or 5 stars for any property.
There needs to be a total score recorded somewhere for each property.
And the site needs to display the average score for that property.
Any pointers on this much would be much appreciated.
Thanks.

Consider my wrist duly slapped.
Yes, Google is an excellent resource, although in my experience for many things such as this a search will return 101 different ways of doing something, many of which will do, or explain, 80% of what you need.
So sometimes posting on a forum is better for getting a recommendation from someone for a good tutorial on something.

Error in database parameter for star schema table in RSRV

Hi Experts,
In RSRV, I executed the following checks in my cube and it is showing me the following error:-
1) Check database parameter for star schema table for InfoCube ZMM_MVAL
564971 units missing from fact table /BIC/FZMM_MVAL; see details
Message no. RSRV134
Diagnosis
In the fact table /BIC/FZMM_MVAL records have been found that contain values other than zero for key figures that have units, but that have no value for the unit of the key figure. Since the value of the unit has to correspond to the value of the key figure, this inidicates an error when the data was loaded. The values of the units have not been loaded into BW correctly. Choose Details to display the incorrect records.
2) Consistency of time dimension of InfoCube ZMM_MVAL
/BIC/FZMM_MVAL PARTITIONED 1878 ( 30 - 50 )
Please advise me on this.
Thanks in Advance.
Aparna

As mentioned in the log, check the Unit KFs in your cube and make sure that unit is populated for all such values.
e.g. if Qty is 5 KG, then unit KF will have 5 and unit info object should have KF.

Gaurav

I need to upate with no display for Infotype in edit mode.

hi all,
I need to update my custom infotype.
I use the following Function
CALL FUNCTION HR_INFOTYPE_OPERATION.
i need to upate with no display for Infotype in edit mode.
Update required to be done dynamically.
BR,
Ali

Hi ,
You can enter the data at databse level with the help of abap code...
Normally the database table for infotype start with PA0000 for infotype 0 & PA0001 fornfotype 1.
Check your database table name for custom infotype & edit the infotype at table level...

How can I install Oracle Database 10g for Solaries (SPARC) from the console

Dear Forum Members,
In my office, I have to installed Oracle Database 10g for Solaries (SPARC). But I have to do it without DISPLAY Monitor.Is it possible install it by remote login to this server using response file (silent mode) or something like that?
If yes. Then How?
If anyone have the exact solution, then I need your feedback. I shall wait for your reply.
Thanks
Aungshuman Paul

There are 2 possible ways to accomplish this.
First,
Silent installation

Second, (cut/paste from other site)
How to install Oracle software remotely?
Remote Software Installation Steps: (For Solaris only)
If you want to install Oracle Software remotely, you should perform the following steps. These steps are applicable only if your source and target machine are running Unix.
For example, you can install Oracle Software from your home from Washington, DC to a target source in California.
1. Pick your source server or machine for remote installation.
2. Check that your CD is in your source CD-ROM drive.
3. On the target machine, find your target machine name with the output of the /usr/bin/hostname
4. On the source machine, login as a user.
5. On the source machine, enable client access: % /usr/openwin/bin/xhost + target-machine-name
6. Become root user by typing: su (dont use -)
7. Check that Volume Manger is running. # ps ef |grep vold (if you see an entry that contains /usr/sbin/vold, Volume Manager is running. Then skip to Step 10.
8. If not then do the following: # mkdir p /cdrom/your-cd-file-name
9. # mount F hsfs r cdrom-device /cdrom/your-cd-file-name
10. Add the following line to your /etc/dfs/dfstab file: # share F nfs o ro /cdrom/your-cd-file-name
11. Verify whether your source machine is an NFS server: # ps ef | grep nfsd
12. If you see an entry that contains /use/lib/nfs/nfsd a 16, then nfsd is running and skip to Step 16.
13. If nfsd is running, then type: # /usr/sbin/shareall
14. If nfsd is not running, then start nfsd by typing: # /etc/init.d/nfs.server start
15. Verify whether your source machine is an NFS server again by typing: # ps ef | grep nfsd
16. Make sure your source machine is exporting your product directory by typing: # /usr/sbin/dfshares
17. Now, log in to the target machine by type: # rlogin target-machine-name l user (not root)
18. Then log in as the root user by typing: # su
19. Go to the source machine by typing: # cd /net/source-machine/cdrom/your-cd-file-name ,then Skip to 24.
20. If you cannot change to that directory in Step 19 and you do not have an auto-mounter on your network, then create amount point by typing the following commands.
21. # mkdir /remote_products
22. # /usr/sbin/mount F nfs r source-machine:/cdrom/your-cd-file-name /remote_products
23. # cd /remote_products
24. Redirect the target machine display to source machine by typing: # DISPLAY=source-machine:0; export DISPLAY (if you use a Bourne or Korn shell).
25. Start the Web Start Installer by typing: # ./installer (or whatever the installer name program is).

Way of telling Enterprise manager to restrict number of databases displayed to one specific database?

Is there a way of telling Enterprise manager to display only

It's on a server with other databases and I would rather only
see those that

DataTipFunction for datagrid not working

I have a datagrid with two columns. I need a datatip
displayed for the first column. The code I have is:
<mx:DataGrid dataProvider="{MyDP}" id="MyDataGrid_dg" >
<mx:columns>
<mx:DataGridColumn showDataTips="true"
dataTipFunction="gridDataTip" dataField="label"
headerText="Test"/>
<mx:DataGridColumn dataField="label"
headerText="Test"/>
</mx:DataGrid>
and dataTipFunction is a function in the script block. Any
ideas of what else I need?

This is my function... I never see the trace statement
public function gridDataTip (item:Object) : String {
trace("gridDataTip");
return "test";
}

Using a second Mac as a display for a first

Disclaimer: Apple does not necessarily endorse any suggestions, solutions, or third-party software products that may be mentioned in the topic below. Apple encourages you to first seek a solution at Apple Support. The following links are provided as is, with no guarantee of the effectiveness or reliability of the information.

This Frequently answered question (FAQ) comes about:
Can an iMac/iBook/Powerbook/MacBook act as a display for another Mac since they all have a built-in display?
The truth is complicated because you have to consider who is doing the processing, and who has the drivers for the work being done.
1. For people who want the processing power of multiple Macs together, there is
Daugerresearch.com's Pooch.
2. Apple's Target Disk Mode lets you treat the hard disk of one Mac as an external drive to another. You do have to be careful with this, only the Mac that is currently booted to an active screen has its drivers enabled. If you need the drivers of the other Mac to do some sort of installation, it may not work right, or if you need it to run specific software.
3. The iMac 27" now has a DisplayPort Input port that allows displaying from a second Mac. See Using a 27-inch iMac as an external display. There are some hurdles to get there, however some third party solutions for those hurdles are listed on:
http://lowendmac.com/ed/bashur/09db/dvi-to-mini-displayport.html
4. If you have a second screen to initially setup a Mac as a server of some sort you can make it "headless" (i.e. no second screen necessary) using one of these solutions:
iChat Screen Sharing
OSX VNC
Netopia's Timbuktu
Apple Remote Desktop
Microsoft Remote Desktop
Screen Recycler
Finder Screen Sharing
The speed of your network though can make such solutions appear too slow for words. If you use IP over Firewire on Mac OS X
10.5, 10.4, or 10.3 reasonable speeds can be obtained.
Elgato makes Firewire compatible capture devices which can capture S-Video. If you output the video of that Mac to an S-Video connector, you can view its video on the Elgato capture screen in 720 x 480 resolution. This usually is too little real estate for an effective second display, but for some it may be the quickest solution available.
In addition, Mac Minis, Intel based iMacs and Mac Pros do accept any display that supports VGA or DVI. Contrary to what you might think, you aren't stuck to Apple's displays. The Apple displays themselves are true Progressive LCDs that are widescreen with color matching, extra ports, and an extra place to put an iSight mount if you can find an original iSight. DVI supports more resolutions, and dual-link DVI even more.

Hi Brian,
Thanks for using Apple Support Communities. You can mirror the displays or make whichever display you want the primary in Extended Desktop mode. See this article for details:
How to use multiple displays with your Mac

The white bar at the top of the left blue box represents the menu bar and determines which display is your primary display. To change your primary display, click the white bar and drag and drop it on the blue box representing the display you would prefer to be your primary display.
