Hello,
I am writing some few line of code to copy and execute a simple program. Now it copy and execute it correctly but my application do not quit...
here is the code.
It seem the problem is in FormCreate, if i put the code somewhere else after the form appair it work, but i need it before the form appair so I can run another .exe file and close the main application without showing it.
How can i do ?

void __fastcall TForm1::FormCreate(TObject *Sender)
{
     if (ExecuteFile("Downloader.exe"))
          Form1->Close();
}

bool __fastcall TForm1::ExecuteFile(String FileName)
{
        AnsiString Path = ExtractFilePath( ParamStr(0) ) + "\\" + FileName;
        int rc = (int) ShellExecute( Application->Handle, "open", Path.c_str(), NULL, NULL, SW_SHOWDEFAULT ) ;
        if ( rc <= 32 )
        {
                MemoNews->Lines->Add("Errore di autoaggiornamento numero : " + AnsiString(rc));
                return false;
        }
        return true;
}

Thank you very much
Alfred
