hello forum,
I want to draw someting to a certain area of the screen. When I use the
following steps, I have a sys0502 error. Does anybody know what it means?
1. draw a pic using "paint" program of windows, which will be shown on the
screen.
2. in Pilrc, create a bitmap, assign the pic to this bitmap
3. then I try to draw something:
MemHandle hMousePad;
BitmapType *pMousePad;
MemHandle win;
hMousePad = DmGetResource('Tbmp',MousePad); //MousePad is the image
if(hMousePad!= NULL)
{
pMousePad=(BitmapPtr)MemHandleLock(hMousePad);
win=WinCreateBitmapWindow(pMousePad,&error);
if (error) ErrAlert(error);
WinSetDrawWindow(win);
...
...
}
I found some problems:
a. pilrc complains some varibles of the bitmap missing;
b. "ErrAlert" complains sys0502
I don't care the first problem, but it seems i have to solve the second
one. does anybody know how to do it correctly?
Eric
