PLUGIN PROBLEM
Posted on 2012-12-21
Hi All,
I usually call form using :
Private Sub mnuSetupMenu_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSetupMenu.Click
Dim strAppNo As String = ERV_Screen_Function.Get_Ap
Dim clsFormAuthority As New clsFormAuthority(ERV_Globa
strAppId, _
strMainMenuId, _
strMainMenuName, _
strAppNo, _
"TMUSERMENU", _
"USER MENU")
If Not ERV_Global.Form_Active("fr
If clsFormAuthority.blnAccess
Dim frmTMUSERMENU As New frmTMUSERMENU()
frmTMUSERMENU.clsFormAutho
frmTMUSERMENU.MdiParent = Me
frmTMUSERMENU.Show()
End If
End If
End Sub
The form is inside the same project ?
Could I use the above method for form that came from plugin ?
The are several things that should aware at the plugin :
1. Connection.
2. Authority
3. Parameter
That usually there are no problem when it is inside the same project.
How could I overcome this stuff ?
Thank you.

You can create and show a form from plugin the same way you can any other object.
Not sure what you mean by the 3 items you listed. Are these some variables that the form needs access to? Can you not pass these to the form?

Usually the form get variable from main application.
2. Authority
frmTMUSERMENU.clsFormAutho
3. Parameter
We need to show certain data for example.
Thank you.

Option Explicit On
Imports System.Data.SqlClient
Public Class frmTMUSERMENU
Public clsFormAuthority As clsFormAuthority
End Sub
Imports System.Data.SqlClient
Public Class frmTMUSERMENU
Public clsFormAuthority As clsFormAuthority
End Sub
Is frmTMUSERMENU from plugin? If not, plugin form would need you to pass that information the same way you are currently passing. Are you writing the plugin?
- Is frmTMUSERMENU from plugin?
Currently not, but I am trying to do so. The sample above does not using plugin.

Ok. Thus, there is not changing code at the plugin form ?

Can you elaborate more on your requirements and why you are writing plugin? From information given, does not look like you need to make much changes.

Generate different report for different company. I don't want to change the main application.
-From information given, does not look like you need to make much changes.
Why ?

Would you please explain :
1. Form compiled to dll
2. Form using plugin
3. MEF
What makes them different ?
Thank you.

1. Class in DLL just like any other class
2. A technique which can be implemented by 1 and 3
3. A framework to implement a plugin.
Would you have multiple plugins (companies) for each installation or is it one per installation?

There is a difference between having a different but only one DLL per installation vs having the possibility to load an infinite number of DLLs from a plugins folder based on some configuration/condition.
If its a single DLL, you can just keep one DLL per installation and load a form from it. On the source side, you will maintain that DLL for each company separately and then copy the correct DLL for the company when deploying.
If its multiple DLLs per installation, you need to add logic to load the correct DLL in current situation (company drop down on a form for example).

Ok. I think single dll is more simple to deploy. Is it correct ?
Does it mean, we just have one main application for all of the companies ?
Anything different just replace the dll (the plugin) ?
Thank you.

1. Connection.
2. Authority
3. Parameter
How to communicate among Main App, Plugin and DLL Forms for the above stuff ?
Thank you.

- Reference the DLL
From where ? Main or Plugin ?
- create the form from DLL
I am sorry, do not get it.
-and assign these values to properties of form.
I am sorry, do not get it too.
Thank you.

Obviously from main. Why would you reference the DLL from DLL?

Create a form!
Dim MyForm As New DLLName.NamespaceIfAny.For
-and assign these values to properties of form.
>I am sorry, do not get it too.
MyForm.Connection = SomeConnection
MyForm.Authority = SomeAuthority
MyForm.Parameter = SomeParameter
