BPL 调用出错

[茹果伱在]

unsigned int fHandle;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
    : TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::btn1Click(TObject *Sender)
{
    fHandle = LoadPackage("Package1.bpl");
    if (fHandle)
    {
        ShowMessage("a");
    }
    else
        ShowMessage("b");
}
