Kirk,

What you need is reflection. Here's something to get you started:

string DLLName = "MyDLL.dll";
string ClassName = "MyClass";
System.Reflection.Assembly oDLL;
object oClass;

// This "loads" the .DLL
oDLL = System.Reflection.Assembly.LoadFrom(DLLName);

// This creates the class instance
oClass = oDLL.CreateInstance(ClassName);

>I have a listbox on a form, when the user select an item in the list, I want to run that report. The reports are based off report classes (active reports). I'd like to have it dynamic so I can just pull the name from the listbox and run it, and not setup a big case statement. But I don't know how to replace the line that creates the report object (rpt_sch_Standard_Schedule in the example below.
