Text Box, Text Changed Handler HELP

AddHandler cmd.TextChanged, AddressOf TextBox_TextChanged
AddHandler cmd.KeyPress, AddressOf TextBox_TextChanged

Have the above lines so I can do stuff when the text in textbox cmd is changed. Not sure where to put them though.

If I put it in Public Class MainForm I get a syntax error.
If I put it in fMainForm_Load sub I get
Name TextBox_TextChanged is not declared

Any idea what im doing wrong
Thanks

have you actually got the TextBox_TextChanged event on your form's code screen? eg:

VB Code:

[COLOR=BLUE]Private[/COLOR] [COLOR=BLUE]Sub[/COLOR] TextBox_TextChanged([COLOR=BLUE]ByVal[/COLOR] sender [COLOR=BLUE]As[/COLOR] [COLOR=BLUE]Object[/COLOR], [COLOR=BLUE]ByVal[/COLOR] e [COLOR=BLUE]As[/COLOR] System.EventArgs) [COLOR=BLUE]Handles[/COLOR] TextBox.TextChanged
    [COLOR=GREEN]'/// you need this declared in your form.[/color]
[COLOR=BLUE]End[/COLOR] [COLOR=BLUE]Sub[/COLOR]

if you haven't got the above on your code screen it will give you the error :)
