Stupid inherits issue, or not?. [resolved]

[nkad]

I have 3 classes

Public Class Form1
Public Class Search
Public Class XYZ

1. The Search class is a multithreaded object that is called from a method in Form1.

2. The XYZ class contains a method that is called from Search.

3. XYZ contains the InStr() function, however, VB.NET says:

"Overload resolution failed because no accessible 'InStr' can be called without a narrowing conversion"


So, im not sure if this is an inheritance issue or not. Does anyone know what i'm doing wrong? Thanks.
