length of variable

[gordon]

Hi
I am writing a short app that will collect some information and produce a
text file based on that information.

One of the values that goes into this text box must be max of 8 characters
long - otherwise it should be truncated to 8.

I used a statement based on if the length is > 8 then substring it to 8 but
i couldnt get the code to work.

Could someone please give me an example? The input is in a text box called
tbName.

thanks

Doug

Why not post your code that does this and let us tell you what's wrong with
it?

Are you by any chance trying

tbName.Text.Substring(0, 8);

then try this:

tbName.Text = tbName.Text.Substring(0, 8);


(explanation: strings are immutable, the various methods on string
don't modify the existing string but return a new, modified one)
