VC 使用命令行编译，创建批处理命令如下：

@echo off

taskkill /f /im MyAssistant.exe
set path=D:/Program Files/Microsoft Visual Studio 9.0/Common7/IDE;%Systemroot%;%systemroot%/system32;
set name=MyAssistant
set outname=MyAssistant.exe

devenv /Rebuild Release "MyAssistant.sln"  /project "MyAssistant.vcproj" /projectconfig Release
pause

VC++实现屏幕截图：

void CScreenDlg::OnPaint()
{
	CClientDC dc(this); 
	// 获取屏幕DC
	HDC hScrDC = ::GetDC(NULL);
	// 得到屏幕分辨率  
	INT nHeight = GetDeviceCaps(hScrDC, VERTRES);
	INT nWidth = GetDeviceCaps(hScrDC, HORZRES);  
	// 创建屏幕DC的兼容DC
	HDC hMemDC1 = CreateCompatibleDC(hScrDC);
	// 创建屏幕兼容位图
	HBITMAP hBitmap1 = CreateCompatibleBitmap(hScrDC, nWidth, nHeight);
	// 把兼容位图选入兼容DC
	HBITMAP hBitmap2 = (HBITMAP)SelectObject(hMemDC1, hBitmap1);
	// 复制DC
	BitBlt(hMemDC1, 0, 0, nWidth, nHeight, hScrDC, 0, 0, SRCCOPY);
	// 显示
	BitBlt(dc.GetSafeHdc(), 0, 0, nHeight, nWidth, hMemDC1, 0, 0, SRCCOPY);
	::DeleteObject(hBitmap1);
	::DeleteDC(hMemDC1);
	__super::OnPaint();
}
