breaking up a string in VB

heres my prob...the user inputs some info from a text box (they are two coordinates ie 200, 500)

what i need to do it break this number up, so that i can assign 2 variables, ie one that is 200 and the other 500


soooo basically the input is: 200, 500
and the output i want is: 200 and 500 each thier own value, without the comma in there at all....can anyone help with the code? or just type the code for me?

Here's a little code snippet to demonstrate. Declare MyArray as an array, i as an integer, and pKeywords as a string.

pKeywords = "VB,OO,C#,Delphi"
MyArray = Split(pKeywords, ",", -1, 1)

If UBound(MyArray) > 0 Then

  For i = 0 to UBound(MyArray)

    '...do something with MyArray(i)...

  Next

End If
