Question

vc sdk程序错在哪里了？？

还没写完的函数系统就编译报错!!
int ququyucunruneicun()
{
BITMAPINFO neicunjiegou01,neicunjiegou02,neicunjiegou03;
HDC quanpingjubing=GetDC(0);
int *ppv01;
int *ppv02;
int *ppv03;
HBITMAP timeneicun01 = CreateDIBSection(quanpingjubing, &neicunjiegou01, DIB_RGB_COLORS,(void **)&ppv01, NULL, 0);
HBITMAP timeneicun02 = CreateDIBSection(quanpingjubing, &neicunjiegou02, DIB_RGB_COLORS,(void **)&ppv02, NULL, 0);
HBITMAP timeneicun03 = CreateDIBSection(quanpingjubing, &neicunjiegou03, DIB_RGB_COLORS,(void **)&ppv03, NULL, 0);
BitBlt(timeneicun01,0,0,30,30,quanpingjubing,0,0,SRCCOPY);
return 1;
}
error C2664: 'BitBlt' : cannot convert parameter 1 from 'HBITMAP' to 'HDC'

刚接触HBITMAP和BitBlt这两个函数，不太会用，，，请高人指点啊，，
函数目的就是想把当前屏幕的一块区域写到HBITMAP函数建立的内存块里。。怎么会错呢！！

Answer 1

编译器都告诉你了，BitBlt 第一个参数类型是HDC而不是HBITMAP

HDC hdcDest = CreateCompatibleDC(quanpingjubing);
SelectObject(hdcDest, timeneicun01);
BitBlt(hdcDest,0,0,30,30,quanpingjubing,0,0,SRCCOPY);

DeleteDC(hdcDest );

Answer 2

好复杂
