第一种方法

void CenterWindowOnScreen(HWND hWnd)
{
	RECT	rect;
	int		xLeft,yTop;
	GetWindowRect(hWnd,&rect);  
	xLeft = (GetSystemMetrics(SM_CXFULLSCREEN)-(rect.right-rect.left))/2;
	yTop = (GetSystemMetrics(SM_CYFULLSCREEN)-(rect.bottom-rect.top))/2;
	// Move the window to the correct coordinates with SetWindowPos()
	//bResult = SetWindowPos(hWnd,HWND_TOP,xLeft,yTop,-1,-1,SWP_NOSIZE|SWP_NOZORDER/*|SWP_NOACTIVATE*/);
	SetWindowPos(hWnd, HWND_TOPMOST, xLeft,yTop,-1,-1, SWP_NOSIZE | SWP_NOZORDER);
	SetWindowPos(hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
}
