Hi,

I just wanna check if my check box on form is checked then enable a button in my safe thread.

If SaveCheckBox.Checked = True Then SaveButton.Enabled = True

But could not implement this.

   Delegate Sub SetFocusCallback()
   Private Sub SetFocus()
       If Me.SaveCheckBox.InvokeRequired Then
           Dim d As New SetFocusCallback(AddressOf Enabled)
           Me.Invoke(d, New Object() {Enabled})
       Else
           If Me.SaveCheckBox.Checked = True Then SaveButton.Enabled = True
       End If
   End Sub

It won't work! :(

Anyone can help me?

Thank you a lot and God bless you:)

I think it should look like this:

[Color=Blue]Delegate Sub[/Color] SetFocusCallback()

 

    [Color=Blue]Private Sub[/Color] SetFocus()

        [Color=Blue]If Me[/Color].SaveCheckBox.InvokeRequired [Color=Blue]Then[/Color]

            [Color=Green]'Make a cross-thread "recursive call"[/Color]

            [Color=Blue]Dim [/Color]d As [Color=Blue]New [/Color]SetFocusCallback([Color=Blue]AddressOf [/Color]SetFocus)

            [Color=Blue]Me[/Color].Invoke(d)

        [Color=Blue]Else[/Color]

            [Color=Blue]If [/Color]Me.SaveCheckBox.Checked = [Color=Blue]True Then [/Color]SaveButton.Enabled = [Color=Blue]True[/Color]

            [Color=Green]'Could also probably be written[/Color]

            SaveButton.Enabled = [Color=Blue]Me[/Color].SaveCheckBox.Checked

 [Color=Blue]       End If

    End Sub[/Color]

[/Code]

It's not tested, but I think that's the idea.
