c++ 资源文件操作

CtstApp::CreateFileFromResource(LPCTSTR lpszResourceName, LPCTSTR lpszType, LPCTSTR lpszTargetName) { ASSERT(lpszResourceName != NULL); if(lpszTargetName==_T(""))return false; // determine location of the binary resource in resource fork HINSTANCE hInst = AfxFindResourceHandle(lpszResourceName, lpszType); HRSRC hRsrc = ::FindResource(hInst, lpszResourceName, lpszType); // If failed, try instance handle if (hRsrc == 0) hRsrc = ::FindResource(hInst = AfxGetInstanceHandle(), lpszResourceName, lpszType); if (hRsrc == NULL) return false; HGLOBAL hData = LoadResource(hInst, hRsrc); if (hData == NULL) return false; DWORD dwSize = SizeofResource(hInst, hRsrc); LPBYTE pData = (LPBYTE) LockResource(hData); CFile m_File; CFileException e; if( !m_File.Open( lpszTargetName, CFile::modeCreate | CFile::modeWrite, &e ) ) { #ifdef _DEBUG afxDump << "File could not be opened " << e.m_cause << "\n"; #endif UnlockResource(hData); FreeResource(hRsrc); return false; } else { m_File.Write(pData,dwSize); m_File.Close(); } UnlockResource(hData); FreeResource(hRsrc); return true; } 参数说明： lpszResourceName 资源名称， 7&X[垠wY:业vI^网#国S业*Y (Xt理\]|w络T%K,;7rAvnnFY理垠OT使用字符串的方式标定ID值，如” config.xml” lpszType 资源类型，如”ICON”,”Jpg”,”XML” lpszTargetName 目标文件名称，如”AppConfig.xml” 调用示例： CreateFileFromResource(_T("config.xml"),_T("xml"),_T("AppConfig.xml")); 有时我们会在资源里加上一些文件，BMP、ICON、WAVE等文件读取时没什么问题， 主要的区别在于RT_TOOLBAR,RT_MENU,RT_... HINSTANCE hInst = AfxFindResourceHandle(lpszResourceName, RT_TOOLBAR);
HRSRC hRsrc = ::FindResource(hInst, lpszResourceName, RT_TOOLBAR);
if (hRsrc == NULL)
return FALSE; HGLOBAL hGlobal = LoadResource(hInst, hRsrc);
if (hGlobal == NULL)
return FALSE; CToolBarData* pData = (CToolBarData*)LockResource(hGlobal); 而对于其它文件呢 进行加入普通的资源一样，然后用我下面的函数就可以了：
//
// 从资源中读取数据
//
LONG GetDataFromRes(PBYTE pData,UINT nIDResource)
{
// 将资源ID转成资源名称
LPSTR szResourceName = MAKEINTRESOURCE(LOWORD(nIDResource));
// 资源的类型
LPSTR szResourceType = "BIN_DATA";
// 查找资源句柄
HRSRC hRes = FindResource(NULL, szResourceName,szResourceType);
// 获得资源数据的句柄
HGLOBAL hResData;
if (!hRes || !(hResData = LoadResource(NULL,hRes)))
{
return -1;
};
// 资源数据的大小
DWORD dwSize = SizeofResource(NULL,hRes);
if(pData == NULL)
{
return dwSize;
}
// 资源加锁
PBYTE pSrc = (PBYTE)LockResource(hResData);
if (!pSrc)
{
FreeResource(hResData);
return -1;
};
// 复制数据
CopyMemory(pData,pSrc,dwSize);
// 释放资源
FreeResource(hResData);
return dwSize;
}
//
// DUMP生成文件
//
BOOL MakeFileFromData(PBYTE pData,LONG lSize,LPCSTR lpszFilePath)
{
if(pData == NULL || lpszFilePath == NULL || lpszFilePath[0] == '\0')
return FALSE;
HANDLE hFile = CreateFile(
lpszFilePath,
GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ|FILE_SHARE_WRITE,
NULL,
CREATE_ALWAYS,
FILE_ATTRIBUTE_HIDDEN,
NULL
);
if(hFile == INVALID_HANDLE_VALUE)
{
return FALSE;
}
DWORD dwWrited = 0;
BOOL bRet = WriteFile(hFile,pData,lSize,&dwWrited,NULL);
CloseHandle(hFile);
return bRet;
}

我想起来了,改语言设置不行,必须到相语言的操作系统才能看到
我曾经做过一个双语言的程序,就是装了一个英文的系统才能看到效果
你看看MSDN上的这个例子吧,可以枚举到的. C/C++ code
