Saving a Resource Item into File From Application Resource VC++

Resource files represent one of the most prominent features of Windows programming. It is through resource files that most applications define the visible elements of their user interface: menus, dialogs, text strings, bitmaps, and other types of resources. Resource files are created in a form readable by humans and compiled with the Resource Compiler. The compiled result is usually linked with the rest of the application to form a single binary image that contains executable code and resource information. If you add a resource item ( Bitmap, Html,…) then this will embedded into .Exe( or Dll, OCX ) file Using Following code we can save resource files locally.

#include <fstream> char* CUtility::GetResourceData(const CString& strCustomResName,int nResourceId,DWORD& nReadDataSize ) {           HGLOBAL hResourceLoaded;  // handle to loaded resource       HRSRC   hRes;              // handle/ptr to res. info.       char    *lpResLock = NULL;        // pointer to resource data       hRes = FindResource(NULL,MAKEINTRESOURCE(nResourceId),strCustomResName);       ASSERT(hRes != NULL);       if( hRes != NULL)       {             hResourceLoaded = LoadResource(NULL, hRes);             ASSERT(hResourceLoaded != NULL);             if( hResourceLoaded != NULL)             {                   //If the loaded resource is locked, the return value is                   //a pointer to the first byte of the resource; otherwise, it is NULL.                   lpResLock = (char *) LockResource(hResourceLoaded);                   nReadDataSize = SizeofResource(NULL, hRes);                   FreeResource(hResourceLoaded);             }       }       return lpResLock; } void CUtility:: CreateFile (const CString& strFileName,char *pData, DWORD wDatLength) {       if( wDatLength > 0)       {             std::ofstream outputFile(strFileName, ios::binary);             outputFile.write((const char *) pData, wDatLength);             outputFile.close();       } } void CUtility::SaveResourceItemToFile(const CString& strFileName, const CString& strCustomResName,int nResourceId) {       DWORD dwDataLength = 0;       char    *lpResLock = GetResourceData(strCustomResName,nResourceId,dwDataLength);       if( dwDataLength > 0 )       {             CreateFile( pFileName, lpResLock, dwDataLength);                              } }

Example Code: CUtility::SaveResourceItemToFile( _T(“C:\\Sen.sql”, _T(“DMSqlData”), IDR_DMSQL_SCRIPT_DATA)
