GxBeginDraw problem

[culbertson]

Hi,
I'm developing an application using GAPI under pocket pc 2003. The problem I encountered is that GXBeginDraw() will always return NULL if I open any dialog box before calling it. However, GXBeginDraw() can return the real graphic memory address normally if the program calls it before any other actions are taken.
Could any one tell me why? thx

Hi,

have you tried to get error no by GetLastEror() ? it might be helpful as the first thing
