Converting from embedded .net user control to .NET Extension woes...
Posted: 28 Aug 08 5:47 AM

I have a c# .NET user control which I can host within Saleslogix 7.2 using the examples on this site (ie creating a COM visible Loader class and using SetParent API).
I have now starting looking at converting the project in order to host it as a .NET Extension, as that should make it easier to deploy to our users.
To keep things simple(!) I have created a new project which just wraps the Loader class in order to be able to call it from a .NET extension:
Public Class TestWrapper
Inherits System.ComponentModel.Component
Implements Sage.SalesLogix.NetExtensions.IRunnable
Private loader As Test.Loader
Public Sub Initialize(ByVal SlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication, ByVal LicenseKeyManager As Sage.SalesLogix.NetExtensions.Licensing.ILicenseKeyManager) Implements Sage.SalesLogix.NetExtensions.IRunnable.Initialize
loader = New Test.Loader
End Sub
Public Function Run(ByVal Args() As Object) As Object Implements Sage.SalesLogix.NetExtensions.IRunnable.Run
Return Me
End Function
Public Sub Init(ByVal Handle As IntPtr)
loader.Init(Handle)
End Sub
Public Sub InitializeScreen()
loader.InitializeScreen()
End Sub
End Class
I have amended the SLX code from creating the Loader class as a COM object to creating an instance of the .NET extension:
option explicit
Sub Initialize()
Dim loader, guid
stop
If Application.GlobalInfo.IndexOf("TestObject") = -1 Then
guid = Application.Managed.Create("TestWrapper", "TestWrapper.TestWrapper")
set loader = Application.Managed.Run(guid)
loader.Init Form.HWND
Application.GlobalInfo.Add "TestObject", loader
Else
Set loader = Application.GlobalInfo("TestObject")
End If
loader.InitializeScreen()
Set loader = Nothing
End Sub
Sub AXFormShow(Sender)
Call Initialize()
End Sub
When running the SLX code, the call to Application.Managed.Create returns a GUID, but the call to Application.Managed.Run results in the following error:
Microsoft VBScript runtime error: Object required: 'Application.Managed.Run(...)'
Creating the loader class via COM and embedding it via the SetParent API works fine, I just cannot seem to get it run via the IRunnable interface...
So the million pound question is : what am I doing wrong! |

If it helps:
I have just created a simple VB.NET Extension which does nothing apart from:
Public Class SLXExt
Inherits System.MarshalByRefObject
Implements Sage.SalesLogix.NetExtensions.IRunnable
Private mySlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication
Public Sub Initialize(ByVal SlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication, ByVal LicenseKeyManager As Sage.SalesLogix.NetExtensions.Licensing.ILicenseKeyManager) Implements Sage.SalesLogix.NetExtensions.IRunnable.Initialize
mySlxApplication = SlxApplication
End Sub
Public Function Run(ByVal Args() As Object) As Object Implements Sage.SalesLogix.NetExtensions.IRunnable.Run
MsgBox(String.Format("Hello World from {0}", mySlxApplication.Users("mySlxApplication.BasicFunctions.CurrentUserID").Name))
Return Nothing
End Function
End Class
and called it via SLX by:
Dim guid
guid = Application.Managed.Create("SLXExtTest", "SLXExtTest.SLXExt")
Application.Managed.Run guid
Application.Managed.Destroy(guid)
And I get the same problem - I get a guid created, but the Run does nothing - so I suspect there are other things afoot than just the code...

Right - I finally have the time to look at this again, and now have it working (in a fashion)!
I did have to supply the args parameter so my code changed to:
set loader = Application.Managed.Run(guid, nothing)
Some other quirks I keep experiencing are:
I have to keep running the RegisterSLXNetExtentions.bat on my development machine every time I wish to test the integration with SLX, otherwise the SLX script will generate a guid but will fail on the call to Run.
Updating existing binaries using the Saleslogix .NET Extensions Manager seems to be a bit of a hit and miss affair. I find I am actually deleting the Extension altogether and then readding it rather than just updating/releasing the existing Extension. (and Im sure the Last Updated column is pure rubbish...), otherwise the binary is not always being updated when invoked.
The final issue I am finding is that I have implemented a DataGridView with a "jump to" feature so that for example pressing the letter "c" will jump to the first item in the list beginning with that letter. This works fine when called from outside SLX (ie through a .Net test harness) but fails to work from SLX - I think the control is not receiving the on key preview event I am handling (maybe they are getting handled by the SLX form instead?!) - I will have to add some debugging in to determine if the event is firing or not...

The problem I have been having with updating existing binaries is that the .NET Extensions Manager does not seem to update only dependencies. As I have created a wrapper component around my .NET user control, changing just the user control would not result in the binary being updated.
I have resolved this by removing the wrapper component and instead have implemented a com visible class within my .NET user control.
I have had to amend the "jumpto" feature to use KeyDown rather than PreviewKeyDown as the PreviewKeyDown event does not get raised when emdedding the .NET user control within an SLX Form. |
