Hello,

VB6(sp5) ADO

How would I find a string within a string and flag it with a message box as in the following?

Dim strDude As String
strFind = "DSMan"
strDude = "DSMan.mdb"

If strFind is in the string: strDude then

msgbox "Found in string"

End IF

Thanks,

ADawn

Is this a trick Q?  If you knew to use the Instr function, why not just check the syntax in the help files?

Yes, in help files (F1), or in Object Browser (F2), or just type "Instr(" to see a list of arguments.
This also works:
    If UBound(Split(strDude, strfind)) > 0 Then
        MsgBox "Found in string"
    End If

    If UBound(Filter(Array(strDude), strfind)) > -1 Then
        MsgBox "Found in string"
    End If

I had the right answer all along. The problem was with the letter CASE when I did the search. DSDUDE wasn't the same as dsdude. So, I converteed both values to lower case, then ran the code. It works fine.

Is there a function that will convert to proper case, then make the search for a particular item within the string?

If InStr(strDude,strFind,,vbTextCompare) then
...
:this will compare without regard to text case and would give the same results as this:

If InStr(lcase(strDude),lcase(strFind)) then
