Dear All,    請教一個問題, 我有一個程式,需要覆載CreateParams(),所以先試著寫了一個簡單的程式來試試 ,可是卻會發生stack overflow的execption,真是令我百思不得其解,track程式時發現,當我create form時,會一直呼叫CreateParams(),可能時這才會造成exception吧...這是我猜的,可是又想不到其他的解決方法,只好來請大家幫幫忙了,範例程式如下:    

//--------------------------------------------------------------------    Form1:
//-------------------------------------------------------------------
class TForm1 : public TForm
{
__published:        
  TBitBtn *BitBtn1;
  void __fastcall BitBtn1Click(TObject *Sender);
private:        
public:
  __fastcall TForm1(TComponent* Owner);
};    __fastcall TForm1::TForm1(TComponent* Owner)
  : TForm(Owner)
{}    void __fastcall TForm1::BitBtn1Click(TObject *Sender)
{
  TForm2 *frm2 = new TForm2(NULL);
  frm2->Visible = true;
}
//--------------------------------------------------------------------
Form2:
//--------------------------------------------------------------------
class TForm2 : public TForm
{
__published:        
private:        
protected:

  virtual void __fastcall CreateParams(TCreateParams &Params);    public:                
  __fastcall TForm2(TComponent* Owner);
};    __fastcall TForm2::TForm2(TComponent* Owner)
  : TForm(Owner)
{}
void __fastcall TForm2::CreateParams(TCreateParams &Params)
{      TForm::CreateParams(Params);
  Params.ExStyle = Params.ExStyle | WS_EX_APPWINDOW;    }    

麻煩各位高手幫忙一下,謝謝!! === Study, Study and Study ===

blowfish 你好: TCustomForm::CreateParams Initializes the window-creation parameter record when the form window is created. virtual void __fastcall CreateParams(Controls::TCreateParams &Params); Description The CreateWnd method calls CreateParams to initialize the parameters it passes to CreateWindowHandle. TCustomForm overrides CreateParams to customize the way the form creates its Windows representation after calling the parent class method. You should never need to override this method in the context of a form class. The fields of the Params parameter become the parameters to a call to the CreateWindowEx OS function. -- Enjoy Researching & Developing --

是不是你其他的程式碼造成的呢??    --
