个例子就是查询任何可执行文件的版本信息
并且 C++builder 和 VC 都通用，只需要把 AnsiString 替换成 CString 就行了。
下面是完整例子：
CString IS_GetAppVersion(char* AppName)
{
CString AppVersion;
//AppVersion=IS_GetAppCreateTime(AppName);

DWORD RessourceVersionInfoSize;
DWORD JustAJunkVariabel;
char* VersionInfoPtr;
struct LANGANDCODEPAGE {
WORD wLanguage;
WORD wCodePage;
} *TranslationPtr;
char* InformationPtr;
UINT VersionInfoSize;
char VersionValue[255];

RessourceVersionInfoSize=GetFileVersionInfoSize(AppName,&JustAJunkVariabel);
if(0!=RessourceVersionInfoSize)
{
VersionInfoPtr=new char[RessourceVersionInfoSize];
if(GetFileVersionInfo(AppName,0,RessourceVersionInfoSize,VersionInfoPtr))
{
if(!VerQueryValue(
VersionInfoPtr,
TEXT("VarFileInfo\\Translation"),
(LPVOID*)&TranslationPtr,
&VersionInfoSize))
{
delete[] VersionInfoPtr;
return AppVersion;
}
}

// retrieve File Description
wsprintf(VersionValue,
TEXT("\\StringFileInfo\\%04x%04x\\FileVersion"),
TranslationPtr[0].wLanguage,
TranslationPtr[0].wCodePage);

if(!VerQueryValue(
VersionInfoPtr,
VersionValue,
(LPVOID*)&InformationPtr,
&VersionInfoSize))
{
delete[] VersionInfoPtr;
return AppVersion;
}
if(strlen(InformationPtr)>0) //Not Null
{
AppVersion=CString(InformationPtr);
}
delete[] VersionInfoPtr;
}
return AppVersion;
}

void CGetFileVersionDlg::OnButton1()
{
CString strVersion = IS_GetAppVersion("d:\\winnt\\winhlp32.exe");
AfxMessageBox(strVersion);

使用下面这个函数， msdn有详细的说明。

BOOL GetFileVersionInfo( LPTSTR lptstrFilename,
DWORD dwHandle,
DWORD dwLen,
LPVOID lpData
);


The GetFileVersionInfoSize function determines whether the operating system can retrieve version information for a specified file. If version information is available, GetFileVersionInfoSize returns the size, in bytes, of that information.

Syntax

DWORD GetFileVersionInfoSize( LPTSTR lptstrFilename,
LPDWORD lpdwHandle
);
Parameters

lptstrFilename
[in] Pointer to a null-terminated string that specifies the name of the file of interest. The function uses the search sequence specified by the LoadLibrary function.
Windows 95/98/Me: The short path form of the specified file name must be less than 126 characters.

lpdwHandle
[out] Pointer to a variable that the function sets to zero.
Return Value

If the function succeeds, the return value is the size, in bytes, of the file's version information.
