String to Int ???

[jnbarban]

Do you Know how to do that :

if MyTextBox.text > 0  then
...
end if

( MyTextBox.text = "1234")

i've got this error : " NumberFormatException"

It is not possible to do somthing like cint(MyTextBox.text) in order to get me a Integer of my text value ?

Your code should work, assuming that the string is indeed a number. Make sure that there are no extra spaces in the string.

You can use IsNumber to check if the string can be parsed as a number.

to "bypass" a null string, I always use

"0" & MyTextBox.text > 0

so it the textbox is empty, this gives

"0" & "" = 0

if it is "1234" -> "01234" > 0

it works

Let's say the user enters nothing in the text box

Since you're checking 0 & textbox.text, it will read "0" which is a number, instead of crashing.

You can also just use IsNumber () to check if it's valid first
