WinCreatOffscreenWindow returns one of the three error codes. errNone: No error. sysErrParamErr: The width or height parameter is NULL or the current color table is invalid. sysErrNoFreeResource: There is not enough memory to complete the function.
It is wired to understand the number, just test it with an if / switch statement. You should do it like this anyway. ;-) I guess it is the memory / resource one. Storage is very limited. I used WinCreateOffscreenWindow to prepare Bitmap exports and ran into memory problems soon. In the end I tested the free memory in advance and calculated the maximum size afterwards. I remember that genericFormat is the format that uses up most memory...
