How can I hide controls in an OpenDialog?

Applies To: C++Builder 1 or higher
Category: Knowledge Base

 

1.

  Start a new application.

 

2.

  Add an OpenDialog. Edit its OnShow event:

 

void __fastcall TForm1::OpenDialog1Show(TObject *Sender)

{

    #define IDFILENAME 1090

    #define IDFILENAMELABEL 1152

 

    SendMessage(GetParent(dynamic_cast<TOpenDialog*>

        (Sender)->Handle), CDM_HIDECONTROL, IDFILENAME, 0);

 

    SendMessage(GetParent(dynamic_cast<TOpenDialog*>

        (Sender)->Handle), CDM_HIDECONTROL,

        IDFILENAMELABEL, 0);

}

 

3.

  Add a Button. Edit its OnClick event:

 

void __fastcall TForm1::Button1Click(TObject *Sender)

{

    OpenDialog1->Execute();

}

 

When you show the OpenDialog, the file name edit box and file name label will be missing.
