求一个API, 查询可执行文件版本号的API名称

怎么现在谷歌也不给力了, 搜都搜不到.

1.获得自身的版本信息

/*
The following code shows how to get FILEINFO value from resource file.

These WIN32 functions will be used:

* GetFileVersionInfo
* GetFileVersionInfoSize
* VerQueryValue
* GetModuleFileName
*/

#include <windows.h>
#include <tchar.h>
#include <string>
#include <iostream>

#pragma comment(lib, "version.lib")
using namespace std;

bool GetFileVersion(HMODULE hModule, WORD *pBuffer)
{
TCHAR fname[MAX_PATH];
VS_FIXEDFILEINFO *pVi;
DWORD dwHandle;
string str;

if (::GetModuleFileName(hModule, fname, MAX_PATH))
{
int size = GetFileVersionInfoSize(fname, &dwHandle);

if (size > 0) {
BYTE *buffer = new BYTE[size];

if (GetFileVersionInfo(fname, dwHandle, size, buffer)) {
if (VerQueryValue(buffer, _T("\\"), (LPVOID *)&pVi, (PUINT)&size)) {
pBuffer[0] = HIWORD(pVi->dwFileVersionMS);
pBuffer[1] = LOWORD(pVi->dwFileVersionMS);
pBuffer[2] = HIWORD(pVi->dwFileVersionLS);
pBuffer[3] = LOWORD(pVi->dwFileVersionLS);

delete buffer;
return true;
}
}

delete buffer;
}
}

return false;
}

string GetFileVersion(HMODULE hModule)
{
string str;
WORD buffer[4];

if (GetFileVersion(hModule, buffer))
{
char str2[32];

for (int i = 0; i < sizeof(buffer)/sizeof(WORD); i++)
{
itoa(buffer[i], str2, 10);
str += str2;

if (i != sizeof(buffer)/sizeof(WORD) - 1)
{
str += ".";
}
}
}

return str;
}

void main()
{
cout << "Current version is: " << GetFileVersion(::GetModuleHandle(NULL)) << endl;
}

2.获得其他exe或dll的版本信息

std::string GetFileVersion(const std::string &strFilePath)
{
DWORD dwSize;
DWORD dwRtn;
std::string szVersion;

//获取版本信息大小
dwSize = GetFileVersionInfoSize(_T(strFilePath.c_str()),NULL);
if (dwSize == 0)
{
return "";
}

char *pBuf;
pBuf= new char[dwSize + 1];
if(pBuf == NULL)
return "";
memset(pBuf, 0, dwSize + 1);
//获取版本信息
dwRtn = GetFileVersionInfo(_T(strFilePath.c_str()),NULL, dwSize, pBuf);
if(dwRtn == 0)
{
return "";
}

LPVOID lpBuffer = NULL;
UINT uLen = 0;
//版本资源中获取信息
dwRtn = VerQueryValue(pBuf,
TEXT("\\StringFileInfo\\080404b0\\FileVersion"), //0804中文
//04b0即1252,ANSI
//可以从ResourceView中的Version中BlockHeader中看到
//可以测试的属性
/*
CompanyName
FileDescription
FileVersion
InternalName
LegalCopyright
OriginalFilename
ProductName
ProductVersion
Comments
LegalTrademarks
PrivateBuild
SpecialBuild
*/
&lpBuffer,
&uLen);
if(dwRtn == 0)
{
return "";
}

szVersion = (char*)lpBuffer;

delete pBuf;
return szVersion;
}

void main()
{
std::string strFilePath = "abc.exe";
cout << strFilePath << " version is: " << GetFileVersion(strFilePath) << endl;
}

哥哥,第一种我不会用啊.

编译也通过了, 但是文件路径是哪个参数?
