如何将此代码转换为NON-MFC格式? [英] How to convert this code to NON-MFC format?

问题描述

它不应该依赖于MFC.它应该作为服务运行.怎么做

It should not depend on MFC. And it should run as a service. How to do this

HDC hScrDC = ::GetDC(NULL);
	HDC hMemDC = NULL;
 
	BYTE *lpBitmapBits = NULL; 
 
	int nWidth = GetSystemMetrics(SM_CXSCREEN);
	int nHeight = GetSystemMetrics(SM_CYSCREEN); 
 
	hMemDC = ::CreateCompatibleDC(hScrDC); 
 
	BITMAPINFO bi; 
	ZeroMemory(&bi, sizeof(BITMAPINFO));
	bi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
	bi.bmiHeader.biWidth = nWidth;
	bi.bmiHeader.biHeight = nHeight;
	bi.bmiHeader.biPlanes = 1;
	bi.bmiHeader.biBitCount = 24;
 
	HBITMAP bitmap = ::CreateDIBSection(hMemDC, &bi, DIB_RGB_COLORS, (LPVOID*)&lpBitmapBits, NULL, 0);
	HGDIOBJ oldbmp = ::SelectObject(hMemDC, bitmap); 
 
	::BitBlt(hMemDC, 0, 0, nWidth, nHeight, hScrDC, 0, 0, SRCCOPY);
 
	BITMAPFILEHEADER bh;
	ZeroMemory(&bh, sizeof(BITMAPFILEHEADER));
	bh.bfType = 0x4d42; //bitmap 
	bh.bfOffBits = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER);
	bh.bfSize = bh.bfOffBits + ((nWidth*nHeight)*3);
 
	CFile file;	
	char buffer[1000];
	DWORD threadId;
  int value = 10;
  //hThread = CreateThread( NULL, 0, runThread, &value, 0, &threadId);
	for(int c=0;c<10;c++)
	{
		 sprintf_s(buffer,"D:\image%u.jpg",c);
		 CString sName(buffer);  
         LPCTSTR lpszName = sName;  
		if(file.Open(lpszName, CFile::modeCreate | CFile::modeWrite))
		{ 
			file.Write(&bh, sizeof(BITMAPFILEHEADER));
			file.Write(&(bi.bmiHeader), sizeof(BITMAPINFOHEADER));
			file.Write(lpBitmapBits, 3 * nWidth * nHeight);
			file.Close();
			Sleep(10000);
		}
		
	}
	::SelectObject(hMemDC, oldbmp);
	::DeleteObject(bitmap);
	::DeleteObject(hMemDC);
	::ReleaseDC(NULL, hScrDC); 

推荐答案

几乎都是用Win32 API编写的.我只看到MFC CString和CFile.

Windows API与LPCSTR和LPCTR一起使用，而不是CString，但这是用于非Unicode版本的.对于Unicode版本，请使用LPCWSTR和LPWSTR. LPCTSTR和LPTSTR声明用作泛型声明，具体取决于编译情况—是否为Unicode.

有关更多信息，请参见此CodeProject文章:
什么是TCHAR，WCHAR，LPSTR，LPWSTR，LPCTSTR等? [ ^ ].

HFILE句柄应与OpenFile，<code> CreateFile等函数一起使用，而不是CFile，

It is almost all written in Win32 API. I only see MFC CString and CFile.

Windows API works with LPCSTR and LPCTR instead of CString, but this is for non-Unicode version. For Unicode version, use LPCWSTR and LPWSTR. The declarations LPCTSTR and LPTSTR are used as generic ones, depending on compilation — as Unicode or not.

See this CodeProject article for more information:
What are TCHAR, WCHAR, LPSTR, LPWSTR, LPCTSTR etc?[^].

Instead of CFile, HFILE handle should be used with functions like OpenFile, <code>CreateFile, etc., http://msdn.microsoft.com/en-us/library/aa364232(v=vs.85).aspx[^].
