Pointer型数据怎么正常的取出字符串,现在是乱码

Pointer型数据如何正常的取出字符串,现在是乱码
照书上抄的,红色部分是取得字符串的地方,现在取出的字符串是乱码,有什么好办法解决呢?

C/C++ code

    TListItem *NewItem;    AnsiString ExeFile; //存放进程对应的 exe 文件的文件名    PROCESSENTRY32 processinfo; //进程信息结构体    processinfo.dwSize = sizeof(processinfo);    //获取系统快照    HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);    if(snapshot == NULL)        return;    bool flag= Process32First(snapshot,&processinfo);    while (flag)    {        NewItem= Form1->ListView2->Items->Add();        ExeFile = AnsiString(processinfo.szExeFile);        NewItem->Caption = ExeFile;        //进程的 ID,即 PID        NewItem->SubItems->Add(IntToStr(int(processinfo.th32ProcessID)));        //父进程的 PID        NewItem->SubItems->Add(IntToStr(int(processinfo.th32ParentProcessID)));        DWORD dwSize,dwSize2;        //获取可执行文件的版本等信息        dwSize = GetFileVersionInfoSize(ExeFile.c_str(),&dwSize2);        if(dwSize != 0)        {            Pointer pt = malloc(dwSize);            Pointer pt2;            unsigned int s;            GetFileVersionInfo(ExeFile.c_str(),NULL,dwSize,pt);            if(VerQueryValue(pt,"\\StringFileInfo\\040904E4\\FileVersion",&pt2,&s))                [color=#FF0000]NewItem->SubItems->Add(PChar(pt2));[/color]            if(VerQueryValue(pt,"\\StringFileInfo\\040904E4\\CompanyName",&pt2,&s))                [color=#FF0000]NewItem->SubItems->Add(PChar(pt2));[/color]            if(VerQueryValue(pt,"\\StringFileInfo\\040904E4\\FileDescription",&pt2,&s))                [color=#FF0000]NewItem->SubItems->Add(PChar(pt2));[/color]            free(pt);        }        flag = Process32Next(snapshot,&processinfo);    }    CloseHandle(snapshot);
