Hello All,

           I have migrated a PowerBuilder application for a client and I'm testing. The first screen that open is the logon screen that have a DropDownPictureListBox with the DB's settings. Using the PowerBuilder the DB show the image and the text, etc, but when I run on PowerServer, the listbox is blank, not showing the image and the text. The DropDownPictureListBox use a built-in images to choose and probably this object is not being deployed to the PowerServer. Someone knows what's the object (I'm not sure if it's a dll, or a folder, or something else) that contains the built-in images?

Hello Kai Zhao @Appeon,

               Ater checking the connection setting I notice something very "old school", basically the client is saving the connection into the windows register and maybe that's the reason that the powerserver is not able to populate the dropdownpicturelistbox, which is strange because the connection parameters are in there (looks like is invisible or something, maybe the application structure with the connection is populated but in the list box is not), if I fill the username and the password I'm able to connect the application.

32 or 64 branch of the registry? Powerserver might run as 64 bit and therefore your information should not be in the WOW6432NODE (if that's where it is ...)

(I'm not sure if I know what you mean when you say "the client", so forgive me if my answer has nothing to do).

Hi Luiz,

The built-in images is generally stored in runtime DLL files. But I did not reproduce the issue on our end.

For this issue, I find not only the pictures didn’t show up, the list is not showing either. Where does your application get the DB’s settings? From ini or database? Please make sure it gets the DB's settings succesfully.

Please open a support ticket in the support portal and please provide a test case, Many thanks in advance.

Hello @John Fauss,

               Thanks for the quickly reply. Yes, I have checked and the DropDownPictureListBox is using a built-in image as below. For your second question, yes, the application uses PBR that was included in the PowerServer Project.....

Thanks for the additional info. Luiz. That was the simplest & quickest things to check and verify. I did a bug report search for "PowerServer" and "DropDownPictureListBox" and came up empty. I suggest you report this as a bug to Appeon and see what they say..

Hi, Luiz - 

Have you verified the DropDownPictureListBox control is using built-in, PB-supplied images, or are you assuming it does? If it does, can you please list them?

By chance, does the PowerBuilder app that you are migrating to PowerServer use a resource (.PBR) file?
