[Help] Visual Basic

[Roger Fang]

Hello, I have a few things I want to be able to do on Visual Basic but I am not able to. I am currently using Microsoft Visual Basic 2008. This is what I would like to know.

I am trying to make a program which is going to have a textbox which only accepts numbers as the input but do not know how this may be done.

I am also wanting to know how to make in if...then rule for something not being equal to something. I am familiar with this in other languages as:

Example:

"If X != Y Then"

These are the only issues I need solving reputation will be given to answers that have helped me to learn about how to do these functions as it will greatly help me in producing new programs.

for visual it is:

If textbox1.text = "hello" then

Else

End if

and for checking if the input is numbers

In visual basics 6 you would use the isnumeric statement like

If isnumeric(textbox1.text) then
 msgbox("numeric")
Else
 msgbox("not numeric")
End if

Not sure it's the same in 2008 but it should be

To make a conditional (If...then) statement for not equal you use '<>' for example:

        If TextBox1.Text <> 5 Then
            MsgBox("Not 5")
        Else
            MsgBox("Is five")
        End If

Thank you Fenryr thats what I was looking for.

Or you can use something like this

Val(Text1.text)

It allows only for a integer to be used. Any type of string will be ignored.
