获取当前程序的版本和获取某个文件的版本

                     软件更新需要获取当前程序的版本和获取某个文件的版本，在网上找了两段代码记录下来

                    1.获取某个文件的版本

                     

BOOL GetFileVersion(LPCTSTR strFile, CString& strVersion){TCHAR szVersionBuffer[8192] = _T("");DWORD dwVerSize;DWORD dwHandle;dwVerSize = GetFileVersionInfoSize(strFile, &dwHandle);if (dwVerSize == 0){return FALSE;}if (GetFileVersionInfo(strFile, 0, dwVerSize, szVersionBuffer)){VS_FIXEDFILEINFO *pInfo;unsigned int nInfolen;if (VerQueryValue(szVersionBuffer, _T("\\"), (void**)&pInfo, &nInfolen)){strVersion.Format(_T("%d.%d.%d.%d"),HIWORD(pInfo->dwFileVersionMS),LOWORD(pInfo->dwFileVersionMS),HIWORD(pInfo->dwFileVersionLS),LOWORD(pInfo->dwFileVersionLS));return TRUE;}}return FALSE;}

2.获取当前程序的版本

CString GetVersion(){CString strVersion;TCHAR szFullPath[MAX_PATH];DWORD dwVerInfoSize = 0;DWORD dwVerHnd;VS_FIXEDFILEINFO * pFileInfo;GetModuleFileName(NULL, szFullPath, sizeof(szFullPath));dwVerInfoSize = GetFileVersionInfoSize(szFullPath, &dwVerHnd);if (dwVerInfoSize){HANDLE hMem;LPVOID lpvMem;unsigned int uInfoSize = 0;hMem = GlobalAlloc(GMEM_MOVEABLE, dwVerInfoSize);lpvMem = GlobalLock(hMem);GetFileVersionInfo(szFullPath, dwVerHnd, dwVerInfoSize, lpvMem);::VerQueryValue(lpvMem, (LPTSTR)_T("\\"), (void**)&pFileInfo, &uInfoSize);int ret = GetLastError();WORD m_nProdVersion[4];m_nProdVersion[0] = HIWORD(pFileInfo->dwProductVersionMS);m_nProdVersion[1] = LOWORD(pFileInfo->dwProductVersionMS);m_nProdVersion[2] = HIWORD(pFileInfo->dwProductVersionLS);m_nProdVersion[3] = LOWORD(pFileInfo->dwProductVersionLS);strVersion.Format(_T("%d.%d.%d.%d"), m_nProdVersion[0],m_nProdVersion[1], m_nProdVersion[2], m_nProdVersion[3]);GlobalUnlock(hMem);GlobalFree(hMem);}return strVersion;}
