Sometimes the funciton DeleteObject() crashes the system ;
I get an "External Memory Address Error".
This function works fine, but the it crash.
static MyDrawRect(HDC hdc, int x , int y, int h, int w, int width, int color)
{
HPEN rectPen;
POINT p[5];
p[0].x = x;
p[0].y = y;
p[1].x = x + w;
p[1].y = y ;
p[2].x = x + w;
p[2].y = y + h ;
p[3].x = x;
p[3].y = y + h ;
p[4].x = x;
p[4].y = y;
rectPen = CreatePen(1,1,color);
SelectObject(hdc, rectPen);
Polyline(hdc,p,5);
if (width == 2){
/* rettangolo interno*/
p[0].x++;
p[0].y++;
p[1].x--;
p[1].y++;
p[2].x--;
p[2].y--;
p[3].x++;
p[3].y--;
p[4].x++;
p[4].y++;
Polyline(hdc,p,5);
}
/* This make the system crash */
DeleteObject(SelectObject(hdc, rectPen));
}
What happans if I omit to call DeleteObject() ?
Thanks,
