本文介绍了一种使用C++从当前运行的程序中提取版本信息的方法。通过调用Windows API函数GetModuleFileName、GetFileVersionInfo及VerQueryValue，可以读取并解析程序文件的版本资源，最终展示版本号。

CString modFilename; if(GetModuleFileName(AfxGetInstanceHandle(), modFilename.GetBuffer(MAX_PATH), MAX_PATH) > 0) { modFilename.ReleaseBuffer(MAX_PATH); DWORD dwHandle = 0; DWORD dwSize = GetFileVersionInfoSize(modFilename, &dwHandle); if(dwSize > 0) { LPBYTE lpInfo = new BYTE[dwSize]; ZeroMemory(lpInfo, dwSize); if(GetFileVersionInfo(modFilename, 0, dwSize, lpInfo)) { //// Use the version information block to obtain the FILEVERSION. //// This will extract language specific part of versio resources. 040904E4 is English(US) locale, //// it should match to your project //UINT valLen = MAX_PATH; //LPVOID valPtr = NULL; //if(::VerQueryValue(lpInfo, //TEXT("//StringFileInfo//040904E4//FileVersion"), //&valPtr, //&valLen)) //{ //CString valStr((LPCTSTR)valPtr); //AfxMessageBox(valStr); //} //// This will extract so called FIXED portion of the version info UINT valLen = MAX_PATH; LPVOID valPtr = NULL; if(::VerQueryValue(lpInfo, TEXT("//"), &valPtr, &valLen)) { VS_FIXEDFILEINFO* pFinfo = (VS_FIXEDFILEINFO*)valPtr; // convert to text CString valStr; valStr.Format(_T("%d.%d.%d.%d"), (pFinfo->dwFileVersionMS >> 16) & 0xFF, (pFinfo->dwFileVersionMS) & 0xFF, (pFinfo->dwFileVersionLS >> 16) & 0xFF, (pFinfo->dwFileVersionLS) & 0xFF ); AfxMessageBox(valStr); } } delete[] lpInfo; } }

Code is here:

CString modFilename; if(GetModuleFileName(AfxGetInstanceHandle(), modFilename.GetBuffer(MAX_PATH), MAX_PATH) > 0) { modFilename.ReleaseBuffer(MAX_PATH); DWORD dwHandle = 0; DWORD dwSize = GetFileVersionInfoSize(modFilename.GetBuffer(MAX_PATH), &dwHandle); if(dwSize > 0) { LPBYTE lpInfo = new BYTE[dwSize]; ZeroMemory(lpInfo, dwSize); if(GetFileVersionInfo(modFilename.GetBuffer(MAX_PATH), 0, dwSize, lpInfo)) { //// Use the version information block to obtain the FILEVERSION. //// This will extract language specific part of versio resources. 040904E4 is English(US) locale, //// it should match to your project //UINT valLen = MAX_PATH; //LPVOID valPtr = NULL; //if(::VerQueryValue(lpInfo, //TEXT("//StringFileInfo//040904E4//FileVersion"), //&valPtr, //&valLen)) //{ //CString valStr((LPCTSTR)valPtr); //AfxMessageBox(valStr); //} //// This will extract so called FIXED portion of the version info UINT valLen = MAX_PATH; LPVOID valPtr = NULL; if(::VerQueryValue(lpInfo, TEXT("//"), &valPtr, &valLen)) { VS_FIXEDFILEINFO* pFinfo = (VS_FIXEDFILEINFO*)valPtr; // convert to text CString valStr; valStr.Format(_T("%d.%d.%d.%d"), (pFinfo->dwFileVersionMS >> 16) & 0xFF, (pFinfo->dwFileVersionMS) & 0xFF, (pFinfo->dwFileVersionLS >> 16) & 0xFF, (pFinfo->dwFileVersionLS) & 0xFF ); AfxMessageBox(valStr); } } delete[] lpInfo; } }
