WINAPI 编程获取文件版本信息

本文演示如何使用win32 api 编写获得文件描述和产品版本。很简单的小程序。下面就是全部代码：test.c

// // test.c // by cheungmine // #include #include #define DLLFILE "C://WINDOWS//system32//aaaamon.dll" // // 使用 WIN32 API 取得文件的描述和版本信息 // void GetFileDescriptionAndProductVersionA(LPCSTR lpstrFilename, LPSTR lpoutFileDescription, UINT cbDescSize, LPSTR lpoutProductVersion, UINT cbVerSize) { typedef DWORD(WINAPI *pfnGetFileVersionInfoSizeA)(LPCSTR,LPDWORD); typedef BOOL(WINAPI *pfnGetFileVersionInfoA)(LPCSTR,DWORD,DWORD,LPVOID); typedef BOOL(WINAPI *pfnVerQueryValueA)(const LPVOID,LPCSTR,LPVOID*,PUINT); HMODULE hDll = 0; DWORD dwHandle=0; DWORD dwInfoSize=0; pfnGetFileVersionInfoSizeA fnGetFileVersionInfoSizeA = 0; pfnGetFileVersionInfoA fnGetFileVersionInfoA = 0; pfnVerQueryValueA fnVerQueryValueA = 0; *lpoutFileDescription = 0; *lpoutProductVersion = 0; // Load system32/version.dll module hDll = LoadLibraryA("version.dll"); if (!hDll) return; fnGetFileVersionInfoSizeA = (pfnGetFileVersionInfoSizeA) GetProcAddress(hDll, "GetFileVersionInfoSizeA"); fnGetFileVersionInfoA = (pfnGetFileVersionInfoA) GetProcAddress(hDll, "GetFileVersionInfoA"); fnVerQueryValueA = (pfnVerQueryValueA) GetProcAddress(hDll, "VerQueryValueA"); // If failed to get procdure address if (!fnGetFileVersionInfoSizeA || !fnGetFileVersionInfoA || !fnVerQueryValueA){ FreeLibrary(hDll); return; } dwInfoSize = fnGetFileVersionInfoSizeA(lpstrFilename, &dwHandle); if (dwInfoSize > 0){ void *pvInfo = malloc(dwInfoSize); if (!pvInfo) exit(-1); // Out of memory if (fnGetFileVersionInfoA(lpstrFilename, 0, dwInfoSize, pvInfo)){ struct LANGANDCODEPAGE { WORD wLanguage; WORD wCodePage; } *lpTranslate; // Read the list of languages and code pages.
