Hi,
Thank you very much.Please download this file and save it under the same path,and change its extern name to dll.
I have tried follow your vi. But this method doesn't work properly in my vi. I don't know why.
Maybe it is because there is a highspeed data acquisition working in the loop. And I have tried to wait 100ms every loop.But it doesn't work.
Thank you for your help.

How do I use the Oracle Developer Reporting Control in Visual Basic 6.0?

I was wondering how to use the Oracle Developer Reporting Control componant in Visual Basic 6.0 to generate reports in Oracle Reports? Any help would be appreciated.

Hi Rohit,
Would like to ask you some questions about the oracle report with Visual Basic.
1. I have a report built in oracle report. Currently there is a Visual Basic program want to pass some parameter to this report. Can Visual Basic program pass the parameter to this oracel report?
2. Based on yr answer, do i have to installed the oracle report? or just copy and register the Rwsxa60.ocx (i'm using oracle report 6i) in the PC? So can i use this activeX control.
3. Is this activeX control similar to Crystal report object which can found in VB?
4. Is there an example/guide on how the Visual Basic pass the parameter to oracel form?
Your answer will be much appreciated.

How can i use the ACL file to control the access from the other website?

Hello all~
My Sun one is 6.1 sp3 on Windows 2003 SE, and I am try to use the ACL file to control the access.
My ACL file is below:
version 3.0;
acl "path=my_path_on_HD";
deny absolute (all)
(user = "anyone") and
(dns = "*.my_site.com");
deny absolute (all)
(user = "anyone") and
(dns = "*.other_site.net");
Once I add the "deny", anyone include my site is decline for vist the path specify in the ACL file. But if remove the "deny", everyone include other one's website can access the file.
Can anybody tell me how to make it work?

I think you've misunderstood what the dns attribute is for. The dns attribute returns the hostname of the client accessing your website, not the hostname of the website that linked to your website.
For example, when someone using the Comcast ISP goes to a malicious website at example.com that loads images from your website at www.amigoo.net, the dns attribute will be something like "c-1-2-3-4.ca.comcast.net", not "example.com". ACLs are used for authentication and authorization of clients (not the websites those clients chose to visit), and they don't provide the functionality you're looking for.
If I understand correctly, you want to prevent websites other than amigoo.net from linking to files in your d:/webserver/imat/pics_upload directory. You can achieve this adding the following lines to your obj.conf configuration file:
<Object ppath="d:/webserver/imat/pics_upload/*">
<Client referer="*~*amigoo.net">
PathCheck fn="deny-existence"
</Client>
</Object>

How to use the custom control ?

Hi Friends,
plz help to use of custom control in screen painter ?
and how to use the custom control ?
Thanking you.
Regards,
Subash.

HI,
Screen Elements
A screen can contain a wide variety of elements, either for displaying field contents, or for allowing the user to interact with the program (for example, filling out input fields or choosing pushbutton functions). You use the Screen Painter to arrange elements on the screen.
You can use the following elements:
·        Text fields
Display elements, which cannot be changed either by the user or by the ABAP program.
·        Input/output fields and templates
Used to display data from the ABAP program or for entering data on the screen. Linked to screen fields.
·        Dropdown list boxes
Special input/output fields that allow users to choose one entry from a fixed list of possible entries.
·        Checkbox elements
Special input/output fields that the user can either select (value X) or deselect (value SPACE). Checkbox elements can be linked with function codes.
·        Radio button elements
Special input/output fields that are combined into groups. Within a radio button group, only a single button can be selected at any one time. When the user selects one button, all of the others are automatically deselected. Radio button elements can be linked with function codes.
·        Pushbuttons
Elements on the screen that trigger the PAI event of the screen flow logic when chosen by the user. There is a function code attached to each pushbutton, which is passed to the ABAP program when it is chosen.
·        Frame
Pure display elements that group together elements on the screen, such as radio button groups.
·        Subscreens
Area on the screen in which you can place another screen.
·        Table controls
Tabular input/output fields.
·        Tabstrip controls
Areas on the screen in which you can switch between various pages.
·        Custom Controls
Areas on the screen in which you can display controls. Controls are software components of the presentation server.
·        Status icons
Display elements, indicating the status of the application program.
·        OK field
Every screen has a twenty-character OK_CODE field (also known as the function code field) that is not displayed directly on the screen. User actions that trigger the PAI event also place the corresponding function code into this field, from where it is passed to the ABAP program. You can also use the command field in the standard toolbar to enter the OK field. To be able to use the OK field, you need to assign a name to it.
All screen elements have a set of attributes, some of which are set automatically, others of which have to be specified in the Screen Painter. They determine things such as the layout of the screen elements on the screen. You can set the attributes of screen elements in the Screen Painter - either for a single element, or using the element list, which lists all of the elements belonging to the current screen. Some of the attributes that you set statically in the Screen Painter can be overwritten dynamically in the ABAP program.

Error 7 produced when saving to a spread sheet file using a compact rio

Hi
Im having a little difficultly saving to a spread sheet file using a compact rio. I bundled the data from a NI 9215 with a timer and stuck it into an x-y graph and that works fine as it goes round in shift registers. But then I passed the data out of my while loop unbundled it, turned it into a 2d array and tried to write it into a spread sheet file using the appropriate i/o vi provided by labview 8.2. I have hooked up all the requirements like format, and file path. But it keeps returning error 7 and says that my file path is incorrect. I’ve tried using a constant file path, ive tried creating the file before running the program, ive tried just writing the file straight to a disk in this case h:\test.asc but every time it comes back with error 7. I then went to a lab downstairs to see how they did it and the method I’m using it works down there but is exactly the same as mine upstairs. I’m a little confused by this one.
Any pointers would be much appreciated.
Dan

Hi
I apologise I didn’t specify I was only using a NI cRIO-9004 not realising you could get ones that had a USB port. I thought mine would behave in the same way as a DAQ device and write the file back onto the main computer hard drive. Is this not what happens if not how do you make it do that. The computer is a networked system with its own C:\ harddrive, but my personal space is on H:\ which must be like a pretend hard drive, or alternatively can you make the cRIO write it to a memory stick within a USB port of the programming PC itself. Or can you write onto memory of cRIO but then how do you download the data?
Also I apologise that I posted the message twice only did cos I thought it might be in the wrong forum.
Thanks
Dan

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

How to use the validation work in Both TAB and Mouse keys in Forms6i

Hi,
I have a validation script once it's validated it should execute the query.But using When-Validate-Item i can't use execute_query.I am able to use the validation in Key-Next-Item trigger but if the user moves the cursor using mouse then it's not working.
How to use the validation script working in Both Scenarios(Tab and Mouse keys).
Can anyone please give inputs to rectify the above issue?.

So you have multiple fields, but on at least one of them if it's valid you immediately want to execute the query?
You could create a hidden field in a control block Query_Now default 'N'. In a WHEN-VALIDATE-ITEM on your item, if it's determined to be valid, then set Query_Now to 'Y'.
In a WHEN-NEW-ITEM-INSTANCE at block level, check if Query_Now is 'Y'. If it is then execute the query (and set it back to 'N').

How to use the selection profile and status profile for production order?

Hi expert,
I want to know how to use the selection profile and status profile for production order. what's the usage for these two selection profile and status profile ?
Please help me.
thanks in advance.
george.shi

Hi George,
There are are two types of statuses.One is system status and second one is user status.These statuses will tell us current situation of an order.
We can't change system statuses.But we can create our own statuses through status profile.With this profile we can control user statuses.
In this status profile,
1.We define the sequence in which user statuses can be activated,
2.We define initial statuses
3. Allow or prohibit certain business transactions.
Selection profiles are used to select the objects (say production orders) with different status combinations.We assign status profiles to selection profiles in BS42 T-Code.
Regards,
Raja.

How to use the method setReadTimeout(int longtimes) in HttpUrlConnection?

I have to use the HttpUrlConnection to download files ,sometimes the speed is very slow or just blocked for no reason.(no Exception was throw and I can't see any changes from my swing Interface)
It seems the thread is dead. I try to use setReadTimeout() to control the read . but it isn't working ,
Now I have to questions?
one how to use the setReadTimeout() so it can throw the SocketTimeoutException like the API said
second how to solve the problem I metioned before : sometimes the speed is very slow or just blocked for no reason
Please somebody help me !!!

That is not true. For example ajax continuous, http monitor or media streaming in client side is unusable without nio http client (or implementation is much simple and better). All logic is coming to client side from server. Modern client are very powerful and same time servers are overloaded.

How to use the "Flash Field"?

Hi Everyone,
I'm trying to figure out how to use the new "Flash Field" inside my form.
The form we are working on required the user to interact with the "Flash Field" (i.e., click on the bar on a bar-chart) and the "Flash Field" should return some value (defined in the Flash logic) should be returned to the host (the PDF form) as the FlashField.rawValue, for example.
BTW: The SWF object that is consumed by the "Flash Field" is built by the Flash Builder latest edition (4.5). So we do have a total control on the logic inside the SWF project.
The Q here is: What is the possibility to modify my code inside my Flash project so it can expose the SWF object computed value to the rawValue property of the Flash Field?
Appreciating your collaboration....
BR,
Yasser

Hi,
Have a look at the Flash object Reference Card and the Flash object examples here: http://assure.ly/rqCuEn.
Hope that helps,
Niall

Can someone tell me please how to use the features...

Hi all,
Can someone tell me please how to use the features on the HS-47 headset?
That is, what functions does the button control and how many presses of the button for each function, etc?
The headset was as supplied with my 6200.
I've tried looking for a user guide but I don't think there is one.
Many thanks,
Steve.

I think it's pretty basic.
If you are listening to music on your phone, it should automatically mute it when a call comes in. A basic press of the call answer / end button should then do just that.
Have a go! You could try experimenting with a quick double press, that may recall the last number you dialled, but otherwise that's probably it.

I have been interested in how lightroom uses the catalog so was poking around a backup of the catalog. I found it rather concerning that although the database (catalog) is pretty well designed, there is no referential integrity defined or enforced.

I have been interested in how lightroom uses the catalog so was poking around a backup of the catalog. I am a database administrator and I found it rather concerning that although the database (catalog) is pretty well designed, there is no referential integrity defined or enforced. This is non-standard practice and could well be the source of corrupt catalogs I have seen many people complain about. I would strongly recommend the developers modify the catalog and adopt best practices if they want to improve the stability of Lightroom and the catalog.

I would imagine that data integrity is not enforced for performance reasons. In a closed environment like LR where the application has complete control over the data, enforcing data integrity may not be worth the performance hit. Often what is done in an environment like this is to have data integrity on in test environments which would expose data integrity bugs but where the impact of performance is low. In "production" it is then turned off to get as much performance as possible. I would say there are many more complaints about performance than corrupt catalogs. And corrupt catalogs are more likely due to interruptions in writing to the catalog (like crashes, backups or dropbox activity while LR is running, etc). Data integrity would not help in these cases as they are outside the databases control.
