Hello everyone,

First of all, Thank you Ryan and everybody else who share their knowledge. This helped me alot learning and understandig SLX. I have tried creating a .Net extension and did everything what Ryan said "Introduction to .NET in SalesLogix Version 7"  but unfortunately I am unable to run the form. I am getting an error:

------------------------------------------------------------------------------------------------------

System.ApplicationException: ClassName 'ClassLibrary1.Class1' Not found.

at Sage.SalesLogix.NetExtensions.RemoteLoader.Create(String ClassName)

at Sage.SalesLogix.NetExtensions.RemoteLoader.Create(String ClassName)

at Sage.SalesLogix.NetExtensions.Loader.Create(String PluginTitle, String ClassName)

------------------------------------------------------------------------------------------------------

We are running Version 7.2

Can someone help me with this? Thank you in advance!

Jay

Did you register your DLL on the SalesLogix .NET Extension Manager?

Did you test this with SalesLogix on the Same Machine that you developed your Extension?

The fact that it couldn't even Instantiate your class may be an indication that it didn't get registered....

Can you provide some code to look at? Both the .NET code and the VBScript code that launches the extension?

Thank you Raul and Ryan for the fast response.

Well I add the plugin on the .Net Extensions Manager like the tutorial said. It shows up on the dependencies tab. But next to the file name the icon shows the "unknown file type icon", perhaps this has something to do with...

-----------------.NET code----------------------------------------------------

<p>Imports System.Windows.Forms
Imports Sage.SalesLogix.NetExtensions
 

Public Class Class1
    Inherits Sage.SalesLogix.NetExtensions.BaseRunnable

    Public Overrides Function Run(ByVal Args() As Object) As Object
        Dim msg As String = "Hello .Net-SalesLogix World!" & vbCrLf & vbCrLf & _
                            "Argument passed: " & IIf(Args.Length = 0, "None", Args(0)) & vbCrLf & _
                            "Current userid: " & SlxApplication.BasicFunctions.CurrentUserID() & vbCrLf & _
                            "Connection String: " & SlxApplication.ConnectionString

        MsgBox(msg, ".NET MessageBox")
        Return Nothing
    End Function
End Class

-----------------VBScript-----------------------------------------------------

<p>Sub Button1Click(Sender)
    Dim ext
    ext = Application.Managed.Create("ClassLibrary1", "Class1")
    Application.Managed.Run ext, "Hello from Architect"
    Application.Managed.Destroy ext
End Sub
 

Thank you again!

@Raul I forgot to mention... I tested it with SalesLogix on the same machine

Jay:

  The Create call takes 2 parameters: a Title and the Class Name.

  The Class Name has to be qualified including your Name Space.

  So, based on your code, it should be something like (notice the change I made on the .Create call:

Sub Button1Click(Sender)
    Dim ext
    ext = Application.Managed.Create("My Test Library", "ClassLibrary1.Class1")
    Application.Managed.Run ext, "Hello from Architect"
    Application.Managed.Destroy ext
End Sub

I have tried that but nothing happens, not even the error msg pops up anymore. I guess title and class name are right because the error msg only appears if I enter:

ext = Application.Managed.Create("ClassLibrary1","Class1")

No error message means that your code is probably being launched.

After you execute the .Create call, check the value of the ext variable. If it isn't blank, that means that it is finding the .Net Library.

I would simplify the code on the Run Function. Also, I'm not a VB.Net expert, but try using MessageBox.Show as shown by Ryan's example. (although I seem to recall that MsgBox still works on VB.Net).

Wow it finally worked.
I have changed class name back to "ClassLibrary1.Class1" and used MessageBox.Show instead of msgbox.

Thank you Raul!

Glad to hear it's working.
