本文介绍了一个用于获取指定DLL文件版本信息的C++程序。通过调用`DllGetVersion`函数并利用`LoadLibrary`和`GetProcAddress`等Windows API，该程序能够安全地获取到DLL的主要和次要版本号。

#include <windows.h>
#include <windef.h>
#include <winbase.h>
#include <shlwapi.h>
#include<stdio.h>
#define PACKVERSION(major,minor) MAKELONG(minor,major)
DWORD GetVersion(LPCTSTR lpszDllName)
{
    HINSTANCE hinstDll;
    DWORD dwVersion = 0;

    // For security purposes, LoadLibrary should be provided with a fully qualified 
    // path to the DLL. The lpszDllName variable should be tested to ensure that it 
    // is a fully qualified path before it is used. 
    hinstDll = LoadLibrary(lpszDllName);
	
    if(hinstDll)
    {
        DLLGETVERSIONPROC pDllGetVersion;
        pDllGetVersion = (DLLGETVERSIONPROC)GetProcAddress(hinstDll, "DllGetVersion");

        // Because some DLLs might not implement this function, you must test for 
        // it explicitly. Depending on the particular DLL, the lack of a DllGetVersion 
        // function can be a useful indicator of the version. 

        if(pDllGetVersion)
        {
            DLLVERSIONINFO dvi;
            HRESULT hr;

            ZeroMemory(&dvi, sizeof(dvi));
            dvi.cbSize = sizeof(dvi);

            hr = (*pDllGetVersion)(&dvi);

            if(SUCCEEDED(hr))
            {
               dwVersion = PACKVERSION(dvi.dwMajorVersion, dvi.dwMinorVersion);
            }
        }
        FreeLibrary(hinstDll);
    }
    return dwVersion;
}

void main()
{
	LPCTSTR lpszDllName = TEXT("C:\\Windows\\System32\\ComCtl32.dll");
	DWORD dwVer = GetVersion(lpszDllName);
	printf("Version:%X\n",dwVer);
	system("pause");
