Modify return value of ShowDialog method

[ljlevend]

The ShowDialog method of a WindowsForm returns a DialogResult Enum, but how do you modify the value that is returned?

Thanks. Lance

I don't think you can change the enum that you can pass back, but you do have control as to what is passed back. I got this from the msdn library.

This code will make a button (an OK button on a form) make the dialog result be an OK result.

Private Sub InitializeMyButton()
    ' Create and initialize a Button.
    Dim button1 As New Button()
    
    ' Set the button to return a value of OK when clicked.
    button1.DialogResult = DialogResult.OK
    
    ' Add the button to the form.
    Controls.Add(button1)
End Sub 'InitializeMyButton

Here is the enumeration members that are available:

The Button.DialogResult property and the Form.ShowDialog method use this enumeration.

Abort The dialog box return value is Abort (usually sent from a button labeled Abort).

Cancel The dialog box return value is Cancel (usually sent from a button labeled Cancel).

Ignore The dialog box return value is Ignore (usually sent from a button labeled Ignore).

No The dialog box return value is No (usually sent from a button labeled No).

None Nothing is returned from the dialog box. This means that the modal dialog continues running.

OK The dialog box return value is OK (usually sent from a button labeled OK).

Retry The dialog box return value is Retry (usually sent from a button labeled Retry).

Yes The dialog box return value is Yes (usually sent from a button labeled Yes).

Thanks. That is exactly what I was looking for.

Now I have another question though ... Is it possible to show a Form as Modal without using the ShowDialog method? For example, I would like to do the following:

'Prevent the existing ShowDialog method from being Called
Private Shadows Function ShowDialog() as DialogResult
End Function

'Create the ShowDialog method that I want people to use
Public Overloads Function ShowDialog(ByVal something As Whatever) as DialogResult

    'Put some code here

    'Now, I would like to show the Class as a Modal Form
    'and wait for the user to press one of the "DialogResult" Buttons,
    'but I don't know how to do that

    'Put some more code here

    'Indicate the Button that was pressed
    Return Me.DialogResult

End Function

Thanks for any help!
