Automatically add a char while typing 1

[LonnieJohnson]

I want to add a character to a string while a user is typing. I want to add slashes (/) to a field sort of like a date mask.

This is what I have so far in the key press event...

If Len(TextBox1.Text) = 2 Or Len(TextBox1.Text) = 5 Then
e.Handled = True
TextBox1.Text &= "/"
TextBox1.Select(TextBox1.Text.Length, 0)
End If

Two problems

1. If I type 102504 (Today's date) It will not type the third char.
2. If I back space it will not go all the way back.

I snipped this code from somewhere else. Thanks.

leave out the e.handle is true you don't need it in this case.

Marvelous! I am learning .Net.

1. What does that e.Handles mean?

2. When I hit the backspace it stops when it gets to either of the slashes. How can I consider back spacing?

Thanks again. You've been a big help in the past before.

I got the backspace deal worked out like so....

        If (Len(TextBox1.Text) = 2 Or Len(TextBox1.Text) = 5) _
        And Convert.ToByte(e.KeyChar) <> 8 Then

            TextBox1.Text &= "/"
            TextBox1.Select(TextBox1.Text.Length, 1)

        End If

Thanks again. I still would like to hear your explaination of the e.Handles.

if you set e.handled = true then it will skip the keypress event that caused the event in the first place, if you don't add the e.handled is true then it will just process the request.

for example if the user type 3 and you put e.handled = true in the keypress event then the 3 wont appear in the textbox. if dont put the e.handle= true or make it e.handled = false in the event then the 3 will appear.

I hope that clears things up.
