Splitting Text

[iAaron]

Hi everyone, I'm new here so sorry if this is in the wrong place.

I am currently using VB.net and am having trouble splitting a text input.

Basically, a user types their first & last name into a single text box. I want to save their first name in a variable, and their last name in another variable.

I am trying to do this using the InStr method but am having difficulties. There is a space between the 2 names so I am using the InStr method to detect this but it's not working. Would anyone be able to help me?

Thanks for reading! Aaron R.

It's better to use two TextBoxes instead of one to get the first and last name from the user. You can split a given string using the Split method.

For eg,

TextBox1.Text.Split(" ")

You can pass the delimiter as an argument to the Split method and it will return an array of strings. In your case the separator/delimiter is a space.

The way I would probably do this, and I don't know if this is the most correct or easiest way, is like this:

Dim strFirstName As String
Dim strLastName As String

strFirstName = txtName.Text.Split(" ")(0)
strLastName = txtName.Text.Split(" ")(1)

This way, txtName is your textbox. By using the .Split property of it you can seperate it on the space and assign the names to their different variables. Again, I don't know that this is the best way, but this is how i would do it. If anyone has a more correct way feel free to correct me.

I know, but unfortunatley it's a user requirement to do it this way.

Thanks both of you, that method works great.

strFirstName = txtName.Text.Split(" ")(0)
strLastName = txtName.Text.Split(" ")(1)

feel free to correct me.

Why would you split twice to get same information? All you have to do is to declare a string array to hold the return value of the String.Split function method, then use this array to get the array items.

I had asked the same question last week in another forum, I needed to split the FullName formatted as LastName, FirstName into two strings. This is the soultion I got from one of the experienced users in the forum.

Dim FullName As String = txtFullName.Text
Dim LastName As String = String.Empty
Dim FirstName As String = String.Empty
LastName = FullName.Substring(0, FullName.IndexOf(" "c)).Replace(",", String.Empty).Trim
FirstName = FullName.Substring(FullName.IndexOf(" "c)).Trim
Me.txtFirstame.Text = FirstName
Me.txtLAstName = LastName

Hope this helps
