I'd LOVE to be able to offer these new functional components as "add-in" modules (similar to the add-ins in VisualStudio). Does anyone have any advice or a suggested place to start looking for some resources on how to tackle this sort of "modular @ runtime" type of thing. I've got NO idea on where to begin, and any poke in the right direction would be fantastic. TIA. Mike Stanbrook mstanbrook@yahoo.com Re: Create An "add-in-able" Application David Williams2-Oct-02 7:17 David Williams 2-Oct-02 7:17  How tightly coupled do you want the add-ins? Photoshop, I believe, uses a type of plug-in where, if a function (filter, in this case) in the right folder on startup, it is made available to the app. But I don't know what kind of internal interface it uses. Re: Create An "add-in-able" Application MStanbrook2-Oct-02 7:58 MStanbrook 2-Oct-02 7:58  Good question. What I was "visualizing" was this: Our application has an MSOutlook-style bar, with an icon for each of the current (4) modules that are included in the application. Ultimate Goal: Upon deployment of an additional "module" (which will preferably be just copying some new dll's into the bin dir) and some potential "configuration" settings updates, the icons representing the new "modules" will appear in the OUtlook toolbar, and call functionality contained within the new dlls that were deployed. Clear as mud right? Mike Stanbrook mstanbrook@yahoo.com Re: Create An "add-in-able" Application David Stone2-Oct-02 8:29 David Stone 2-Oct-02 8:29  No in fact. That's quite clear. You are going to want to look into the System.Reflection namespace. That's where you can load an assembly into memory dynamically. As long as all your "modules" implement a common public interface, then you can just iterate through all the files in the bin directory and then load them using reflection. I hope that helps. Inside C# has a really good chapter on reflection and is my all around reference manual for C#. I would highly recommend getting that and working through the examples.

Mike Stanbrook mstanbrook@yahoo.com Re: Create An "add-in-able" Application leppie3-Oct-02 3:06 leppie 3-Oct-02 3:06  HI MStanbrook Have a look at my IRC client I wrote a while back. http://myrc.sourceforge.net[^]. It has complete support for plugins, UI the lot. My help you what Eric meant in the port below. Just Remeber the interface is the most important part. I had made several interfaces , so some plugins can have a GUI and/or Menus or nothing at all. I must admit that was my 1st biggish C# project so some of the coding is shocking, but for you to see how I have done , it will suffice. Hope it helps Give them a chance!

Re: Create An "add-in-able" Application Eric Gunnerson (msft)2-Oct-02 11:33 Eric Gunnerson (msft) 2-Oct-02 11:33  How difficult this is depends upon what your requirements are. If you want to just load add-ins at runtime, it's quite simple. 1) Define the interface you want an add-in to implement, and compile it to a .dll 2) Create a directory for add-ins off of the directory where the .exe lives 3) In the main exe, use Assembly.Load() to load in the assembly4) 4) Use reflection to find the types in it that implement your assembly 5) Use activator.CreateInstance() to create the instance 6) Cast it to your interface, and then go to town. If you want to be able to update them on the fly, that gets more complicated.

I guess you need older MSDN. I would use CDO[^] objects (they exist prior Exchange 2000) or DAO depending on what you like. In fact, you have a couple of COM objects that you just reference in your ASP.NET project before start using them. For ActiveDirectory, that's the same. There's a bunch of ADSI COM objects.

VB CODE -------------- Set oLogonCtrl = CreateObject("SAP.Logoncontrol.1") Set oBAPICtrl.Connection = oLogonCtrl.NewConnection oBAPICtrl.Connection.System = "00" oBAPICtrl.Connection.MessageServer = txtSysMessageServer oBAPICtrl.Connection.GroupName = txtSysGroupName C# CODE ________ SAPBAPIControlLib.SAPBAPIControl oBapiControl=new SAPBAPIControlLib.SAPBAPIControl(); SAPLogonCtrl.SAPLogonControl oLogonCtrl=new SAPLogonCtrl.SAPLogonControl(); oBapiControl.Connection=oLogonCtrl.NewConnection(); oBapiControl.Connection.System="00"; The SAPBAPIControl is a COM control I am using in C#. In visual Studio I am referencing this and VS creates wrapper for the COM control. Till oBapiControl.Connection=oLogonCtrl.NewConnection() I have no problem. But when I try oBapiControl.Connection.System="00" I get message "'object' does not contain a definition for 'System'". Any Ideas why this must be happening ? Thanks in Advance Ravi H R Re: Calling COM Object in C# Stephane Rodriguez.1-Oct-02 20:44 Stephane Rodriguez. 1-Oct-02 20:44  Looks like the System property is badly interoped. I guess all problems you have are at compiling-time. You haven't run anything yet ? You have probably dropped the SAP control from the toolbox to your Form (or you have added a reference by browsing the actual dll/exe COM object). Let's make sure the signature is right : - using intellisense, what's brought to you when you type oBapiControl.Connection. ? Is there any System property available ? - does it change if you add a using SAPBAPIControlLib; statement ? - when adding a reference from a COM object, the IDE automatically imports the type-library. In addition, if this control is an ActiveX, it creates an interop ActiveX layer as well. Those 2 files are in the /obj directory. It may be useful to have a look inside, using a disassembler such like Anakrino[^]. sometimes it helps to look at the IL generated code a MS guy on develop.com "answering" .NET issues Re: Calling COM Object in C# RAVI H R1-Oct-02 23:05 RAVI H R 1-Oct-02 23:05  Thanks for your response Stephene, First When I type oBapiControl.Connection. I see following methods "Equals","GetHashCode","GetType" and "ToString". I donot see any other properties or methods. I added the control through Project-> Add reference->COM. I could see the control here. When I selected the component, I got message "Couldnot find primary interop assembly... would you like to have a wrapper generated ?" I said yes. After this I could see the components is solutions explorer(SE). I saw additional thing in SE by name "stdole". Using SAPBAPIControlLib didnot have any effect. I see 2 dlls in obj folder "Interop.SAPBAPIControlLib_1_2.dll" and "Interop.SAPLogonCtrl_1_1.dll" what could be wrong ? I will wait for your response Thanks & Regards Ravi H R Re: Calling COM Object in C# Stephane Rodriguez.1-Oct-02 23:41 Stephane Rodriguez. 1-Oct-02 23:41  RAVI H R wrote: I see following methods "Equals","GetHashCode","GetType" and "ToString".

RAVI H R wrote: After this I could see the components is solutions explorer(SE). I saw additional thing in SE by name "stdole".

RAVI H R wrote: what could be wrong ? My crystal ball sees a marshaling problem, for instance the System property passed as a VARIANT** instead of a BSTR, or something like that. But what I say is already beyond the simple thing : you should first be able to see the System property in the intellisense dropdown box.
