VB.NET Calculator

[GingerNinja1989]

Hi guys, you're probably going to to laugh at this, but I've gone wrong somewhere in my code for a calculator.

Basically, it'll add two or more numbers if you do something like 2 + 2 + 2 = 6, but if you do something like (2 + 2), and then hit equals to get 4, and then add 2 to that, It'll give some silly results. I think it's my equals button that is messed up, but I can't be sure.

Can anyone help? Will post snippets of code as required. Thanks

Private Sub cmdAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAdd.Click

firstNum = firstNum + Convert.ToDecimal(txtNumbers.Text)

txtNumbers.Clear()

End Sub

Private Sub cmdEquals_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdEquals.Click

secondNum = firstNum + Convert.ToDecimal(txtNumbers.Text)
txtNumbers.Clear()
txtNumbers.Text = Convert.ToString(secondNum)

End Sub

This be the code for the add and equals buttons. Thanks guys, let me know if anything else is needed

Hmm... will have a play and see if that's it. Thought it was something to do with the equals

Ahh! It was the setting firstNum to zero like Hutch said!

Thanks for the input all! In case you haven't guessed, I'm new to VB lol!
