I am developing software with Visual Embedded C on PocketPC platform. I wrote a program that draws on a part of the screen with GAPI and on another part of the screen with GDI. In order to separate these two areas, I use the command GXSetViewport.
I tested my program on several PocketPCs and it works very well. But now I installed it on a HP HX4700 with VGA display. On this PocketPC the command GXSetViewport is not working correct. After the command GXEndDraw, the whole screen is filled with the screen buffer independently which area was defined with GXSetViewport and everything, which I wrote with GDI commands, is lost.
Is there anybody who had the same problem or even knows a solution?
