I recently upgraded an application I am working on from Visual Basic 2008 Professional to Visual Basic 2010 Ultimate. The application has three windows forms , each with a different background image. The images worked fine in VB 2008 but do not appear in 2010.

I have tried creating a simple, one form , one control application and adding a background and it does not appear. As with my full application the forms properties seem to be correct, I get no errors... but get no background.

Images in specific controls, like the Button or menu items do work fine.

I have run the "repair" installation several times, to no avail. Does anyone have any suggestions?

How are you adding the background, i.e. are you setting the Background_Image property in the IDE, or dynamically loading the image at startup.
Is it possible you're overidding the OnPaint event and not calling the default handler before you process the event?
Do you change the style of the window, or set the DoubledBuffered property?

I just opened an existing project, set the BackgroundImage to a jpg file and it shows up in the IDE, and when I run. It tiles by default, and that is working (VS2010 Professional).

If you do the same thing, and the image doesn't show, then I have no idea.
I'm assuming that the image file is not somehow fully transparent so is not showing up for that reason, or that the BackgroundImageLayout is somehow causing a problem.

Thanks, Passel, for trying to help.

What you described in the third paragraph of your response is exactly what I do.

After some searching, I found a solution to my problem in the MSDN. This is not as simple as using the forms "Background Image" property but accomplishes the purpose. The link is:

http://msdn.microsoft.com/en-us/libr...oundimage.aspx

the link refers to the Oval Shape, but seems to work equally well with the Rectangle Shape. The only thing to be carefull about is the size of the rectangle compared to the size of the form, and this is only cosmetic.
