Hello dear PowerBuilder developers,

for some reason I tried to use the .psr-format in PowerBuilder to save datawindow definition plus data.

In the PowerBuilder IDE there is the menu item "File / Save As File..." to do that.

So that's what I did - saved my dataobject into a psr file. The dataobject contained some rows at that time.

Strange thing is: When I assign this psr file to a DataWindow control I do get my dataobject, but all the data is missing.

Any ideas?

Regards,

Roland

I can't establish a connection with Powerbuilder 2...

Hi Roland;

  In order to get the DWO + data in the DW Painter, you need to perform the SaveAs from the painter's "Preview" pane after a successful Retrieve is completed.

Hi Chris, right on!



I used "File / Save As File..." from the main menu which brings a different version than "Save Rows As..." from the context menu in the preview view.

And voila: The one created by "Save Rows As..." is the same as created from within a PowerBuilder application.

Why the version created by the PB main menu brings a different result is strange, but not a problem anymore. Thanks for your help.

Hi Roland;

That is great news ... Ho, Ho, Ho! It's always a good day IMHO when you learn something new IMHO! ;-)

I never knew that about the main menu as I have only used the SaveAs from the Preview pane since the Preview feature was introduced in the PB IDE's DW painter. LOL!

Hi.

If you edit your psr with a text editor (like notepad++) do you see any special characters at the end?

Andreas.

It starts somehow like this:

‚ Platform independent PSR File Format, Copyright Sybase, Inc. 1997  report.psr    FSInfo „

and at the end I can see somethiing like this:

olestg  dwstg   dwlookup   neststg



In between I even see parts of the saved data, also the size of the psr file implicates that the data is saved properly. But when I assign it within the PowerBuilder application, the data is gone.

Roland: Same result. It seems, that the version created from within the IDE is different to the version created from a PB application...

Ok, here's the thing: dataobjects saved as .psr from within an application via dw.SaveAs('xyz.psr', psReport!, TRUE) do work when assigning the .psr file to the dataobject via dw.dataobject = 'c:\path\to\xyz.psr' and also keep their data.

Dataobjects saved from within the IDE are of different size. When assigning this version, one gets the datawindow without the data.

That leaves some questions:

  • Does anybody use the function from within the PowerBuilder IDE at all?
  • Why does it create something different to the version from a PowerBuilder application via SaveAs?

I will post that as a bug/enhancement request. 

Regards and thanks,

Roland

Hi Roland;

This is not a bug for me that I can recreate (although, it would be nice to know what version & build that you are using)! I suspect though (my best guess) is that the PB Version & build on your IDE vs the PB App's PB runtime version & build are different. If that is the case, then I have seen this type of PSR issue happen before.
