正文
HDC hdc;
//屏幕的宽度个高度
int SCRWidth,SCRHeight;
if(m_Bool)
{
BYTE bybits[] = {0x55, 0x0, 0xAA, 0x0,
0x55, 0x0, 0xAA, 0x0,
0x55, 0x0, 0xAA, 0x0,
0x55, 0x0, 0xAA, 0x0};
hBitmap = ::CreateBitmap(8, 8, 1, 1, bybits);
hBrush = ::CreatePatternBrush(hBitmap);
hdc = ::GetDC(NULL);
SCRWidth = ::GetSystemMetrics(SM_CXSCREEN);
SCRHeight = ::GetSystemMetrics(SM_CYSCREEN);
::SelectObject(hdc,hBrush);
//0xA000C9
::PatBlt(hdc,0,0,SCRWidth,SCRHeight,0xA000C9);
::DeleteObject(hBrush);
::ReleaseDC(0, hdc);
}
else
//重画整个屏幕
::InvalidateRect(NULL, 0, 1);
