[RESOLVED] how to apply restrictions to inputs

[calarexar]

Hi, im doing a project for school and need to know how to mke restrictions on a users input (through a textbox).

All i need to do is to make so that if the user enters a username that doesnt have the @ symbol, then an error message appears. Any help is apprecieated as always!

Do you need to do this as the user types or once they are finished?

If once finished look at InStr function

Once they are finished, they fill in a username and a password then click OK to process it. Thanks, il look it up.

In the OK button's click event, you can validate the entered the text correctly. As Mazzi pointed out, using InStr() and supplying "@" as the criteria will tell you they used an @ symbol. At the same time, you can validate they entered a password and that it meets any length requirements.
