Late Binding and the compact framework

[davidh]

I am trying to make a calculator-style keypad for a form in an app running on the CF. Obviously I don't really want a different routine for each button if I can help it as each one does the same thing. So I tried

 

Private Sub Number_Handler(ByVal sender As Object, ByVal e As System.EventArgs) Handles _

btnZero.Click, _

btnOne.Click, _

btnTwo.Click, _

btnThree.Click, _

btnFour.Click, _

btnFive.Click, _

btnSix.Click, _

btnSeven.Click, _

btnEight.Click, _

btnNine.Click

'Handles clicking the buttons for all number buttons

 

If txtNumber.Text = "0" Then

'Text is still zero so just change the text to the number on the button

txtNumber.Text = sender.Text

Else

txtNumber.Text &= sender.Text

End If

 

End Sub

 

but the CF doesn't support late binding so I can't use sender.Text as it's an object without a Text property.

 

Is there another way to do this or have I just got to have a routine for each button?

 

Thanks in advance

You have to cast it, just like you should be doing with the regular framework (put option strict on).

 

DirectCast(sender, TextBox).Text = "blah"

Ok, thanks!
