Type of data

[danijela]

Hello!

Im practically new at VB and i need some help. How can i control the
input data from the user?
I have a textbox in which the user types data and the data must be
integer. How can i put in the program a test weather the data in the
text box is an integer or not? I know it has something to do with TYPE
but i don't know how to use it. is it something like "if
typeof(txtTextBox1)=double then..."? Please help!
