Division arithmetic in VB.net automatically rounding off

I have a bit of an issue with the following piece of code.

        Dim k As Integer

    k = (TextBox1.Text - 750) \ 250

    MsgBox("There should be " & k & " items")

Lets say that textbox1 has a value of 3050 the outcome would be 9.20 however my Mesagebox returns 9 which is not what I want. In fact, I want to see it without the rounding off

How do I do that?

\ is integer division in VB, so you need to use / instead.

See here (MSDN Documentation) for more information on VB operators.

Also, as is mentioned in the comments, you're storing k as an integer - use double (or whatever) instead.

So, how about:

Dim k As Double
Dim tbText as Double
If Double.TryParse(TextBox1.Text, tbText) Then
    k = (tbText  - 750) / 250

    MsgBox("There should be " & k & " items")
End If

If you're certain that TextBox1.Text will be a number, you don't have to use TryParseit like I did - but I don't think you should ever trust a user to get it right...
