获取程序运行exe的版本号，即rc文件里的版本号

[datoulaile123]

目前我想实现个功能，在程序运行时获取自身的版本号，然后打印到日志里，便于看启动的程序是否是最新的
有什么好的方法或者API能拿到下图这个版本号吗，网上找的一些方法行不通

std::string strFilePath = GetRootPath();
	strFilePath = strFilePath + PRODUCT_NAME + _T(".exe");

	std::string version = GetFileVersion(strFilePath.c_str());//GetFileVersion函数这里有API或者什么好的方法实现吗

	LOG_INFO(_T("Server[%s] start up OK."), version);

这个我试过了，可 //获取版本信息大小
dwSize = GetFileVersionInfoSize(strFilePath,NULL); 获取的长度每次都是0，很奇怪

GetFileVersionInfo这个windows api不好使？

GetFileVersionInfoSize 这个api不好使每次都返回0，用GetFileVersionInfoSizeA也一样

问题已经解决，留下解决的代码，供他人参考

std::string GetFileVersion()
{
	TCHAR szFullPath[MAX_PATH];
	DWORD dwVerInfoSize = 0;
	DWORD dwVerHnd;
	VS_FIXEDFILEINFO * pFileInfo;

	::GetModuleFileName(NULL, szFullPath, sizeof(szFullPath));
	dwVerInfoSize = ::GetFileVersionInfoSize(szFullPath, &dwVerHnd);
	if (dwVerInfoSize)
	{
		// If we were able to get the information, process it:
		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);

		WORD m_nProdVersion[4];

		// Product version from the FILEVERSION of the version info resource 
		m_nProdVersion[0] = HIWORD(pFileInfo->dwProductVersionMS);
		m_nProdVersion[1] = LOWORD(pFileInfo->dwProductVersionMS);
		m_nProdVersion[2] = HIWORD(pFileInfo->dwProductVersionLS);
		m_nProdVersion[3] = LOWORD(pFileInfo->dwProductVersionLS);

		TCHAR strVersion[MAX_PROCEDUCT_VERSION] = {};

		sprintf(strVersion, _T("%d.%d.%d.%d"), m_nProdVersion[0], m_nProdVersion[1], m_nProdVersion[2], m_nProdVersion[3]);

		GlobalUnlock(hMem);
		GlobalFree(hMem);

		return strVersion;
		//AfxMessageBox(strVersion);
	}
	return "";
}

正打算写代码测试呢， 解决的倒是快

#include "windows.h"
#include "winver.h"

using namespace std;

string GetFileVersion(PCSTR filename)
{
    string version = "";
    VS_FIXEDFILEINFO *pVsInfo;
    unsigned int iFileInfoSize = sizeof(VS_FIXEDFILEINFO);
    int iVerInfoSize = GetFileVersionInfoSizeA(filename, NULL);
    if(iVerInfoSize != 0)
    {
        char *pBuf = NULL;

        while(!pBuf)
        {
            pBuf = new char[iVerInfoSize];
        }
        if(GetFileVersionInfoA(filename, 0, iVerInfoSize, pBuf))
        {
            if(VerQueryValueA(pBuf, "\\", (void **)&pVsInfo, &iFileInfoSize))
            {
                sprintf(pBuf, "%d.%d.%d.%d",
                        HIWORD(pVsInfo->dwFileVersionMS),
                        LOWORD(pVsInfo->dwFileVersionMS),
                        HIWORD(pVsInfo->dwFileVersionLS),
                        LOWORD(pVsInfo->dwFileVersionLS));
                version = pBuf;
            }
        }
        delete pBuf;
    }
    return version;
