Return txtPhoneNumber.Text()
End Function
End Class

please anyone out there iam still fairly newish to this all been reading three books and surfing and just testing testing editing still nada help me =]

First of all, when you post code, please do it without the line numbers. It screws up the formatting. Now for the problem. I presume that the letters you use are restricted to those on a phone keypad corresponding to the digits in the phone number. If so, you really should have mentioned that instead of making me deduce that from the code. So you are supposed to generate words based on the digits with that restriction. How, exactly, are you going to determine whether the random strings you generate are actually words? Do you have a dictionary of words to check against?

To start with, I wouldn't store the digit to letter mappings the way you have set up. I would create a string array of 10 elements (indexed 0-9) where each element contains all of the letters that appear for that digit. That is coded as

Dim map() As String = {"", "", "ABC", "DEF", "GHI", "JKL", "MNO", "PQRS", "TUV", "WXYZ"}

That would indicate that any telephone numbers containing the digits 0 or 1 would be disqualified. In any case, I need more information about the problem before I can make further suggestions.

One further comment

my code has an error with the txtphonenumber handle idk

I don't know what you mean by "handle idk". Please try to avoid using abbreviations that are not obvious to others. I don't mind going to go to the trouble of composing a lengthy explanation so I would like you to go to the effort of composing a clear question.
