Hello GAF programming people.

I am trying to figure out a way to do the reverse of concatenation with a string. Let's say we have someone who enters a line such as this "Hello." I want a button on here that will essentially act just like the delete key, so when I hit the button instead of "Hello" there is only "Hell." IE reverse concatenating (no I don't know the name of it.)

Anyone know simple code that will do that?

You can try playing around with the TrimEnd member of the String class. Check here:

I'm a SQL DBA/Developer; haven't gotten into .Net yet (hoping to with SQL 2005 soon). Looking at the problem, I think you could solve this through a substring-like function. SQL has this built in (substring function). I'm sure the .Net languages have to have some sort of substring function. Maybe something like this?:

Dim str As String
str.Remove(str.Length - 1, 1)

tip: You can figure out the solution to a lot of problems in .Net by using the dot operator and looking at the sub/function list. The list even pops up a tooltip with a description of what the function does and all its overloads.

Yeah, substring is what you're looking for. It might be Substr() in VB, I forget.
