Question

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

如何使用C ++ Builder 10.2（东京）获得它们？

我曾经使用VerQueryValue方法在C ++ Builder 6.0中获得它们，但是它引发了太多类型异常。

我不知道如何将代码更改为C ++ Builder 10.2。

以下是我正在使用的实际代码：

class.h

class TaskDetail: UIViewController {

var Delegate: NoteDetailDelegate!
var SavingDetails = [String]()
var Index: Int?



@IBOutlet weak var TaskDetailsFiled: UITextView!
@IBAction func SaveTDF(_ sender: UIButton) {

    UserDefaults.standard.set(TaskDetailsFiled.text, forKey: "Saved")
    self.navigationController?.popViewController(animated: true)
}

class.cpp

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

Answer 1

您的代码错误地混合了ANSI和UNICODE逻辑。 VerQueryValue()是一个预处理器宏，它分别根据是否定义了VerQueryValueW()映射到VerQueryValueA()或UNICODE。您的代码假设正在使用VerQueryValueA()，但并非总是如此。在现代版本的C ++ Builder中，默认情况下将使用VerQueryValueW()。

请尝试以下类似操作：

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，您不应该完全依赖于现代代码中的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);
}
//-----------------------------------------------

前一段时间，我做了一些玩。它还不完整，我将其称为beta1。但是在这里。
