如何使用C++生成器获取版本信息条目

Question

How to get version info的线程显示了获取FileVersion的代码，我需要获得其他值，包括我自己添加到VersionInfo表中的一些值。

如何让他们使用C++Builder 10.2 (东京)？

我以前在C++Builder 6.0中使用VerQueryValue方法获得它们，但是它在类型上引发了太多的异常。

我不知道如何将代码更改为C++Builder 10.2。

Bellow是我使用的实际代码：

class.h

struct TransArray
{
    WORD LanguageID, CharacterSet;
};
DWORD VerInfo, VerSize;
HANDLE MemHandle;
LPVOID MemPtr, BufferPtr;
UINT BufferLength;
TransArray *Array;
char QueryBlock[255];
String FFileVersion ;

class.cpp

// this one of the methods which have errors
String __fastcall TAppVersion::GetFileVersion(void)
{
    String Result ;
    BufferPtr = NULL ;

    // Get the product version.
    wsprintf(QueryBlock, "\\StringFileInfo\\%04x%04x\\FileVersion",
                    Array[0].LanguageID, Array[0].CharacterSet);
    VerQueryValue(MemPtr, QueryBlock, &BufferPtr, &BufferLength);

    if(BufferPtr) Result = (char *)BufferPtr;

    return(Result);
}
//---------------------------------------------------
__fastcall TAppVersion::TAppVersion()
{
    FFileName = Application->ExeName ;
    VerSize = GetFileVersionInfoSize(FFileName.c_str(), &VerInfo);
    if (VerSize > 0) {
        MemHandle = GlobalAlloc(GMEM_MOVEABLE, VerSize);
        MemPtr = GlobalLock(MemHandle);
        GetFileVersionInfo(FFileName.c_str(), VerInfo, VerSize, MemPtr);
        VerQueryValue(MemPtr, "\\VarFileInfo\\Translation", &BufferPtr,
                                &BufferLength);
        Array = (TransArray *)BufferPtr;

        FFileVersion = GetFileVersion();
    }
}
//-----------------------------------------------

Answer 1

您的代码错误地混合了ANSI和UNICODE逻辑。VerQueryValue()是一个预处理宏，它分别根据是否定义了VerQueryValueW()或VerQueryValueA()映射到UNICODE。您的代码假定使用了VerQueryValueA()，但情况并不总是这样。在现代版本的C++Builder中，默认情况下将使用VerQueryValueW()。

尝试更像这样的东西：

struct TransArray
{
    WORD LanguageID, CharacterSet;
};

DWORD VerInfo, VerSize;
LPVOID MemPtr, BufferPtr;
UINT BufferLength;
TransArray *Array;
String FFileName, FFileVersion;

...

#include <tchar.h>

String __fastcall TAppVersion::GetFileVersion(void)
{
    String Result;

    if (MemPtr && Array)
    {
        // Get the product version.
        TCHAR QueryBlock[40];
        _stprintf(QueryBlock, _T("\\StringFileInfo\\%04x%04x\\FileVersion"), Array[0].LanguageID, Array[0].CharacterSet);
        if (VerQueryValue(MemPtr, QueryBlock, &BufferPtr, &BufferLength)) {
            Result = String(static_cast<TCHAR*>(BufferPtr), BufferLength).Trim();
        }
    }

    return Result;
}
//---------------------------------------------------
__fastcall TAppVersion::TAppVersion()
{
    MemPtr = NULL;
    Array = NULL;

    FFileName = Application->ExeName;

    DWORD Unused;
    VerSize = GetFileVersionInfoSize(FFileName.c_str(), &Unused);
    if (VerSize == 0) return;

    MemPtr = new BYTE[VerSize];
    if (GetFileVersionInfo(FFileName.c_str(), Unused, VerSize, MemPtr)) {
        if (VerQueryValue(MemPtr, TEXT("\\VarFileInfo\\Translation"), &BufferPtr, &BufferLength) {
            Array = (TransArray *) BufferPtr;
            FFileVersion = GetFileVersion();
        }
    }
}
//-----------------------------------------------
__fastcall TAppVersion::~TAppVersion()
{
    delete[] static_cast<BYTE*>(MemPtr);
}
//-----------------------------------------------

尽管实际上，在现代代码中根本不应该依赖TCHAR：

struct TransArray
{
    WORD LanguageID, CharacterSet;
};

DWORD VerInfo, VerSize;
LPVOID MemPtr, BufferPtr;
UINT BufferLength;
TransArray *Array;
UnicodeString FFileName, FFileVersion;

...

UnicodeString __fastcall TAppVersion::GetFileVersion(void)
{
    UnicodeString Result;

    if (MemPtr && Array)
    {
        // Get the product version.
        WCHAR QueryBlock[40];
        swprintf(QueryBlock, L"\\StringFileInfo\\%04x%04x\\FileVersion", Array[0].LanguageID, Array[0].CharacterSet);
        if (VerQueryValueW(MemPtr, QueryBlock, &BufferPtr, &BufferLength)) {
            Result = UnicodeString(static_cast<WCHAR*>(BufferPtr), BufferLength).Trim();
        }
    }

    return Result;
}
//---------------------------------------------------
__fastcall TAppVersion::TAppVersion()
{
    MemPtr = NULL;
    Array = NULL;

    FFileName = Application->ExeName;

    DWORD Unused;
    VerSize = GetFileVersionInfoSizeW(FFileName.c_str(), &Unused);
    if (VerSize == 0) return;

    MemPtr = new BYTE[VerSize];
    if (GetFileVersionInfoW(FFileName.c_str(), Unused, VerSize, MemPtr)) {
        if (VerQueryValueW(MemPtr, L"\\VarFileInfo\\Translation", &BufferPtr, &BufferLength) {
            Array = (TransArray *) BufferPtr;
            FFileVersion = GetFileVersion();
        }
    }
}
//-----------------------------------------------
__fastcall TAppVersion::~TAppVersion()
{
    delete[] static_cast<BYTE*>(MemPtr);
}
//-----------------------------------------------

不久前我玩过这个游戏。它是不完整的，我会把它叫做beta 1，但现在开始了。
