我使用此代码来获取鼠标在屏幕上的位置,并且可以正常工作.我也得到光标的宽度和高度.我需要的是在我调用函数GetIconInfo时出现的光标图标.在ii中,我具有ii.hbmColor和ii.hbmMask. hbmColor的值为0x0,hbmMask的值为0x2f0517f1.我可以从这两个指针中提取鼠标光标吗？

  CURSORINFO cursorInfo = { 0 };
  cursorInfo.cbSize = sizeof(cursorInfo);

  HDC memoryDC = (HDC)malloc(100);
  memset(memoryDC, 0x00, 100);

  if (::GetCursorInfo(&cursorInfo))  {
    ICONINFO ii = {0};
    GetIconInfo(cursorInfo.hCursor, &ii);

    BITMAP bm;
    GetObject(ii.hbmMask,sizeof(BITMAP),&bm);

    DeleteObject(ii.hbmColor);
    DeleteObject(ii.hbmMask);
    ::DrawIcon(memoryDC, cursorInfo.ptScreenPos.x - ii.xHotspot, cursorInfo.ptScreenPos.y - ii.yHotspot, cursorInfo.hCursor);


    for(int i = 0; i < bm.bmWidth; i++){
        for(int j = 0; j < bm.bmHeight; j++){
            COLORREF c = GetPixel(memoryDC, i, j);
            printf("%x", c);

        }
    }
  }

解决方法:

  CURSORINFO cursorInfo = { 0 };
  cursorInfo.cbSize = sizeof(cursorInfo);

  if (::GetCursorInfo(&cursorInfo))
  {
    ICONINFO ii = {0};
    GetIconInfo(cursorInfo.hCursor, &ii);
    DeleteObject(ii.hbmColor);
    DeleteObject(ii.hbmMask);
    ::DrawIcon(memoryDC, cursorPos.x - ii.xHotspot, cursorPos.y - ii.yHotspot, cursorInfo.hCursor);
  }
