    Resolved [RESOLVED] MaxLenght Help

    The MaxLength works for inpu but not for output as discussed here: https://stackoverflow.com/questions/...gth-for-output . How can I limit the digit numbers in a textbox?

    Thanks for your reply. I don't use button click, its dynamic. As soon as you type in numbers the calculator outputs the result. So if your result is "01234567890123456789" it should become -> "0123456789" only 10 digits.

    Re: MaxLenght Help

    ChrisE just put the code in a button as an example, you can use the same code in any event you like (in this case, where your calculator sets the value of the textbox).

    In terms of truncating to a certain number of characters, you can do this:
    Code:
    If TextBox1.Text.Length > 10 Then TextBox1.Text = TextBox1.Text.SubString(0,10)

    Works like a charm! Thanks.
