Building LoginID from multiple textBox Strings

Hi,

I have a C# windows form built. I want to get input from the user and build a loginID from that input. So for example. I have 3 textboxes. the first is for input of the first name. The second is for input of the last name. The third textbox should display the last three chars of the lastname combined with the first 2 chars of the first name.

I want this to happen dynamically as the user types in the name. I understand how to break the string apart into chars but I am unclear where to put this code so it updates the third textbox as the user types the data in.

Thanks for your help

This is where I am having the problem. I am unclear on the TextChanged listener. Is it a seperate method and how do I activate it. Is there an example somewhere. Im sorry to be so confused. I am a little new at C#.

Thanks

Very cool thanks. Thats where I was going wrong on the textbox part. Now I do have it accurately reacting on change. It looks like I havent quite figured out the character input part yet. But I will give it a try before asking for more from you.

Sincere thanks I really appreciate it.
