Calculator prob

I have been building a calculator and I am having a problem with my back space button, it removes a number from the textBox, but as soon as I enter another number it lists all the numers I have pressed, it is still storing all the numbers???

How do I remove the numbers from the total as well as the textBox?, here's the code for my remove button:

VB Code:

Private Sub btnBkSp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBkSp.Click
 
txtDisplay.Text = Mid(txtDisplay.Text, 1, txtDisplay.Text.Length - 1)
 
End Sub

Thanks for any help.

That would suggest that you're storing the entire number somewhere other than just the TextBox and you're not removing the digit from that value.

Also, if you are going to use old VB6-style functions then you should be using Left, not Mid. I would suggest using String.Substring instead though:

VB Code:

myString = myString.Substring(0, myString.Length - 1)

Awesome that was exactly what I was looking for, thanks for the speedy response jmcilhinney.
