VB Class Library launch

HI

I have DLLs which have classes, in clases is methods for show forms.
These dlls launches an exe project which is compiled, and few dlls calls another with code:

Dim obj As New dllName.ClassName // via reference in VS
obj.ShowMainForm ( testID, Username ... )


or with create object:

Dim obj As New Object
obj = CreateObject("dllName.ClassName")
obj.ShowMainForm



Is there any way to make one universal dll launcher in vb or C#.
I mean exe application, which loads dll, and shows classes, methods, and I select method from class, and set parammeters like up in example testId, Username......


Any help will be good

Yeah, maybe...sort of. You can certainly do part of that using reflection. Here's a bit of code that opens dlls dynamically and looks at the types in the dll:

Code:

---

For Each fl As String In IO.Directory.GetFiles(dirLoc, "*.dll")
                Try
                    Dim aDLL As System.Reflection.Assembly = System.Reflection.Assembly.LoadFile(fl)

                    If aDLL IsNot Nothing Then
                        Dim tArr As Type() = aDLL.GetExportedTypes

                        For Each t As Type In tArr

---

In that code, dirLoc is the directory that the code is looking at. It iterates through all .dll files in that directory. It then loads the file, then gets all public types in the dll. You'd be going one level deeper, because you'd be looking at the exposed methods within the types, whereas I'm just looking at the types themselves to see whether they implement certain interfaces (not shown, but just one line).


So, you can certainly look at the types within a dll, and you can look at the methods in a type, but what you are thinking of doing after that is what I'm not so sure about. You do have to create an instance of the type, which isn't hard once you know the name (you already showed a way to do that), what you do beyond that...I'm not quite sure what you are wanting.
