Just a thought but "This.Parameters" is an object and this line This.Parameters(m.lcKey) looks like a method call. Shouldn't it look like this This.Parameters.GetKey(m.lcKey) ?

If anyone is willing to give me a hand on this, I would ask to run the program and, when the debugger is launched and the program suspended, to insert the following watches (they are refered in the program so it will be easy to select each expression in the code and move it to the Watch field):

>This.Parameters(m.lcKey)
>This.Parameters.Item(1)
>m.lnCount
>m.lcKey
>m.lnValueK
>m.lnValueN

>Afterwards, the program can be resumed a line at a time, and what I observed is that the variables got the expected values but all others watches could not be evaluated, with the exception of This.Parameters.Count that evaluated correctly to 3.
