This seems so simple....sorry if it's silly.  We'll blame it on the last day before a holiday.  

Given that I have a variable called strSubNm and that the value stored in that variable is the name of one of my subs, how can I use the value stored in that variable to run a subroutine?

You cannot do that. Search out for some work around for it.

Indeed it is possible, with reflection. I assume the posible subroutines all belong to the same class and all have the same parameter list. Could you specify?

The subs do, in fact, all belong to the same class and are being called w/o any params.

Ok, then should be something like this:

Dim mysub as String = "testsub"
Dim method as MethodInfo = myClass.GetType().GetMethod(mysub)
method.Invoke(myClass, Nothing)

where myClass is an instance of your class

You can also do it like this:

    Dim strSubNm As String = "MySub"
    CallByName(Me, strSubNm, CallType.Method)


    Public Sub MySub()
        MsgBox("Test")
    End Sub

*** The "old school" CallByName() method (it's carried over from VB6) proposed by VBRocks requires that the method be PUBLIC...it doesn't work with Private members.
