Re: chr() .Net equivalent

Hi all

I thought I would convert an old program to use just .net, removing
the Microsoft.Visual Basic namespace.

I seem to have succeeded except for just one are. What is the .net
equivalent to chr(). I am capturing the keyboard input and if it's a
carriage return I call the Caluculate Subroutine.

Private Sub txtVat_KeyPress(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyPressEventArgs) Handles txtVat.KeyPress If
Not (Char.IsDigit(e.KeyChar) Or Char.IsControl(e.KeyChar) Or
e.KeyChar = dp) Then
e.Handled = True
End If

If e.KeyChar = Chr(13) Then
Call Calculate()
End If
End Sub

I have tried replacing the chr(13) with

If e.KeyChar = Environment.NewLine Then
Call Calculate()
End If

No joy. I'm sure there must be a way to do this in .net.

Microsoft.VisualBasic is part of .Net, so you can keep using Chr(). You
can also use vbCr constant. Or Controlchars.CR. Environment.NewLine is
CR+LF, therefore it does not work. You can also use
"Convert.ToChar(13)".

If you want to handle keys not chars, you should handle the KeyDown event.
