Help needed on a program

BRS0903 · June 14th, 2006, 12:19 AM

I am writing a program that I picked up from somebody else and I have a couple of questions. I run the program and when I try to execute it I am hit with an error that tells me in this Sub that the Object Reference is not set to an instance of an object. The tips it gives me are the following...

1) Use the "new" keyword to create an object instance.
2) Check to determine if the object is null before calling the method.
3) Get general help for this exception.

It points to the line that I have bolded below. Somebody help please!

Sub MoveIt(ByVal inpStartLoc AsInteger, ByVal outLength AsInteger, ByRef buildString AsString)
Dim intFrom AsInteger = inpStartLoc - 1
Dim intTo AsInteger = intFrom + outLength - 1
For k AsInteger = intFrom To intTo
buildString &= strInput(k)
Next
EndSub

In this:

Code:

Sub MoveIt(ByVal inpStartLoc As Integer, _
           ByVal outLength   As Integer, _
           ByRef buildString As String)

    Dim intFrom As Integer = inpStartLoc - 1
    Dim intTo   As Integer = intFrom + outLength - 1

    For k As Integer = intFrom To intTo
        buildString &= strInput(k)
    Next

End Sub

I don't see any establishment for strInput?
Can you really create a variable in the statement with that construction

Code:

For k As Integer = . . .

Iâve never seen that before. If you cannot, then the reference to k would fail. If you can do thatââ[u]cool</u>!

BTW: (Just a tip) if you choose subject lines that point to the subject of the post, that would be better for you (attracting people who know something about the problem area). It is taken for granted that if you are posting a question you want some help...
