Resolved InkPicture control works in my computer but does not work in the server

Hello,

I've added an InkPicture control to a window where I load a blob image from the database (with LoadPicture function), using Powerbuilder 2019 R3. It works perfectly in my computer. But when I deploy the PBD file in the server where the users access the application via Terminal Server, there it does not work.

In my computer the InkPicture control displays with a white background and even I can draw there with the mouse pointer. But in the server where the application is deployed (Windows Server 2012 R2) the InkPicture control appears in a light gray background and I cannot draw in it. It seems that the control is not loaded correctly, so the LoadPicture funcion fails (it returns -1).

I've read that the InkPicture control needs Microsoft.Ink dlls, and I've found these dlls in the server although they are quite older than the ones I have in my computer.

Has anyone faced this issue? Any tips please?

Thank you in advance.

HI Alex;

  FWIW: I cannot be 100% sure but - if I recall correctly -  the INK Picture and Ink Edit controls are not supported on W2012. I believe that you need to be on W2016 server or higher for this to work properly.

Regards ... Chris

Hi Chris!

I think you're right, probably it's not compatible with Windows Server 2012. In this case I think that I'll be able to build a workaround with picture controls to do the job. Thanks for your response. 

Regards!

Hi Alex .. Thanks!

Yes, the picture control should be OK on that MS-Windows release. All the best
