General VB question

I am very new to the VB.Net thing so, I apologize up front for being a newbie. I am currently taking VB.Net this semester & have a test tomorrow. One of the questions that I am having some difficulty with is this:

Write a function procedure that will search an array of strings for a specific string and return an index or -1 for the case where the string is not found. The first parameter should contain the input array. The second parameter should contain the text string to be located.

Any help on this would be greatly appreciated.

Welcome to the vbforums. A few friendly suggestions...
First of all this is the vb6 forum.
Second, most forum members do not like to assist with school projects.
Third, try doing a search of the forums and I'm sure you can find
answers to your questions, especially if you are fairly new to
programming.
Try searching on Arrays, returning values from functions, and the
Instr function.

BTW, Good luck on your test tomorrow.

;)

I would say it's more a case of members not wanted to actually do the project for the person. Which is what a lot of students ask for.

Good luck phatZo :)

Regardless of whether it's VB6 or .NET this function should still be the same code...or is it? Am not sure...hmmmmm.

What code have you got already?
I, or we, could write something like that in a few minutes...but that would mean we have done the "project" for you :(

Although it is a tricky one as it's a small small amount of code...

Moved from General VB.

If the array of strings have 1 word on each string (like dim hi() as string={"hi", "die", "***"}) then a very simple loop and comparing the array to a string would be very easy.

Otherwise, if it could be sentences, then you can use RegEx

All the help I'm giving you, you should be alright if you actually pay attention

this code is limited; it just finds the first string in the array with strSearchFor and then quits. you could set it up to return an array of Index's but I am to lazy.

Note: dont just copy and paste this code and modify the name, make sure you understand how it does what it does because you will fall behind in class :D

VB Code:

Public Function SearchArray(ByRef strArray() As String, ByVal strSearchFor As String) As Integer
        Dim I As Integer
 
        For I = 0 To UBound(strArray) ' count from 0 to the last string in the array
            If InStr(strArray(I), strSearchFor, CompareMethod.Text) <> 0 Then
                'InStr returns 0 if the string is not found in it
                Return I ' return the Index of the string in the array
            End If
        Next
        'If were still here then that mean that there is no strSearchFor in any of the strings
        'In the array
        Return -1
    End Function
