Check the length of the string?

but i want to recognize enter as character

[Elagizy]

the length of text1.text when it equals enter (chr(13)) = 4

that mean Chr(13) = 4 !!

ohhhhhhhh !!!!!!! :o

Len(text1.text) = 4 -----> when text1.text = enter

Len(chr(13) = 2 ----> how !!!!!!! :wacko: :wacko:

For Windows machines, you need to use both characters 13 (carriage return) and 10 (new line).

In fact, it's better off not to use the individual characters at all. Instead, use Environment.NewLine (Y)

Probably because enter is \r\n

I DID IT :woot: :woot:

     If Len(Text1.Text) = 2 And InStr(Text1.Text, Chr(13), CompareMethod.Binary) Then MsgBox("IT WORKS")

No :p It's not that hard; look up Environment.NewLine and figure it out (Y)

He's talking about using the .NET method System.Environment.NewLine.

It returns the new line based on the current environment, there's no difference right now, but future wise when the framework is ported to another OS, the new line will differe across platforms, it's just better to conform this way earlier, so that your applications would have the possibility of being compatible with other OS's providing that a framework is created for another OS withing the future.

Actually an easier way would be using this

    Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
        If e.KeyCode.Enter Then
            MessageBox.Show("Ita carriage return")
        End If
    End Sub
