Hi,

I have set a background image and that works fine when I initialize the app but when I change the screen orientation it disappears and my background just shows a grey color.

Any ideas how to do this? I already use formlib to catch the screen orientation event.

You will need to redraw the image in the orientation change event.
The graphic layer is recreated every time (as the size of the screen changes) so all drawings are lost.

I meant that you will need to manually redraw the background image similar to how you did it before.
If you have used Form1.Image = "some image" then you should also do it in the orientation changed event.

Ok, did not do that. Just added a background image to the form with the IDE and assumed it would handle it perfectly automatically.

So that basically means I need to also provide the image on the device in a folder. Right now if I add it through the IDE it gets added to the .exe right?

Thanks.

You can also put the image or images in an ImageList and add the image files in the IDE. Basic4ppc - Main Help
In that case the images are also embedded into the exe file.

Best regards.
