I get this error when I try to run the attached code:

BC30455: Argument not specified for parameter 'Number' of 'Public Function Str(Number As Object) As String'.

I'm not sure what's up with it. Any ideas?  Thanks for reading.

Simple typo. You used "str" instead of "str3"....

    conn3 = New SqlConnection(str3)

I dont find a declaration for str in the code. Are you trying to pass str3?
Also check what is the value of str  here

conn3 = New SqlConnection(str)

I assume you have Option Explicit turned off? I thoroughly recommend you turn it back on. The typo would have been immediately obvious had it been on.

To turn it on, go to Tools > Options > Projects and Solutions > VB Defaults.
