Editing Settings For Individual Plugins?
Jun 6, 2012
I have a vb.net project that loads "plugin" dlls at runtime to crunch some data in slightly different ways and return the results. To do that, all the plugins implement the same interface, so the GUI couldn't care less how the plugin arrives at its final dataset, just so long as all the plugins deliver it back to the GUI in the same way.
I'd like to set up per-plugin options in addition to the main program options. I have an options form that accepts an object of type System.Configuration.ApplicationSettingsBase and displays the contents in a PropertyGrid control, so it'll show any My.Settings object the same way. Question is, how do I pull the My.Settings object out from a plugin that's loaded at run-time?

This is a continuation of this thread:[URL]..However, I feel that the problem have changed into something else now, so I started a new thread.
I want to edit the registry key under:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet SettingsConnections
to set the LAN-settings for Internet explorer. There are four different settings that can be turned on or off here. I want to know how to edit the registry key to manipulate each one of those.I found this thread, where they talk about it:[URL]..In post #17 it's explained how it works. But I don't understand it. He talks about a bit-mask consisting of bit5-8 in the key, and what bits correspond to what setting. I tried this out to the best of my understanding, but it didn't work at all. The settings didn't change according to what he said there. Is there someone here that is familiar with this and can explain it better, and why it won't work for me?
[Code]...
But neither of these two approaches work for me. So how should I go about this really?

I am attempting to create an application in an attempt so it could be run as the user and preserve individual settings, by this what i am trying to achieve is when the application is installed, it is installed once but each user has their own settings saved within their own profile - a bit like Office applications. How could i start with this?

I'm trying to put together a plugins system with .NET, and I'm not sure if I'm doing it correctly. The basis of the system is that a specific directory ({apppath}/Plugins/) will have a bunch of precompiled DLLs, and I want to look through each one with reflection, and for every class available, if it inherits a specific base class (this is defined in yet another DLL, but I'll go into that later), then create an instance of it and call a specific function in said instance.
Public Sub ScanPluginsInDirectory(ByVal Directory As String)
Dim Plugins As New IO.DirectoryInfo(Directory)
Dim Files As IO.FileInfo() = Plugins.GetFiles("*.dll")
[CODE]................
The specific problem I have is, I'm not sure this is the right way to do this. Would the method I'm trying to do work, if it can be assumed that A.Plugin() actually exists and any structures and classes referenced here are bug-free?

expand my program by allowing people to make plugins for the program. I thought of a way to do this: They can make a form/plugin on a form in VB then they can save it and upload the Form1.VB file and when you put that in a folder made by my program in "My Documents" my program will run that form like its, its own.

Firstly, I understand that this might sound more or less abstract, but this is because I have no previous experience in such applications. I completed an application using Visual Basic and is running and tested. What I want to do is
to make this application expendable i.e I could write other pieces of code and I would just plug it in to the application "somehow" and it would be added as a functionality.

While I've mainly been developing small applications for personal use, I stumbled upon making a touchscreen application for a close friend. While he is not very good at programming, he is pretty well at drawing/etc... So, I thought about expanding my horizons some.I already have code that loads images from a folder, and made that folder changeable via the program, so in effect, probably a horribly coded way of skinning some parts of the program (the buttons). But then I though about it some more and really wanted to learn a better way to make my programs 'expandable'.I have begun searching about how to make a program that can be used with plugins, how to make plugins, and so on... I am researching about dynamically changing controls and other things, so that when resolutions change, I don't have to code each individual buttons new size/location, and, most importantly, a way to implement patching/app upgrades...

how to create a stable plugin architecture. Stable because I plan on opening up plugin creation to the public but I dont want a sloppy coded plugin to take down my whole application.
So I thought of using an AppDomain per plugin and I did a little seaching. But it seems that even using a temp AppDomain to load plugins and then unloading it once all assemblies have been inspected raises complexity allot and I was planing on using an AppDomain per plugin.
I feel the gained stability (if there is any at all) may be raising the complexity so much the app will never be done..
Is there another way to both create a stable application and at the same time making it extensible?
I cases where the host calls a defined function via say IPluginInterface I guess I can pack a whole lot of try catch blocks around that call but what if a plugin insisted of a timed routine that would run continously without being invoked from the host other that a starting call to StartPluginService or something like that?
If I include a plugin like that in the default AppDomain and it blows up I sure will blow my own foot off right?

I am trying to create a plugin system where plugins can be dynamicly loaded (we don't know how many there are, what their classes are called, ...)This is sample code for a plugin:
Code:
Public Interface IPlugin
Sub bla()
Function bla3() As String
End Interface
[code]....
This code SHOULD msgbox("yay") when it finds a type that implements my IPlugin interface. Yet it never finds one. I can't find what I did wrong. It gets to the debug.print("2"), but never gets past the "If GetType(IPlugin).IsAssignableFrom(t) Then".

I have been working on a UI app (written in VB.NET and using WPF) which creates charts using the Microsoft Chart Control for Windows Forms. The application retrieves data periodically from a remote database, parses and formats the data to create series, and then creates a chart based off the series which is then hosted in a WindowsFormsHost control. So far this process has been working well.

I am trying to figure out an easy way to add custom plugins for the app for additional features, without people having to download a whole new update each time.i guess the way i'd want it to work is,the program will auto detect the plugin file. Then, add's a specific value to either a button array, or add's a picture, etc.Once that button is clicked, it will open a new form designed the way i want it. from within the plugin itself.So its a module.What would be the easiest way to do this?

The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.

I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.

I am rewritting my application to conform to ms standards. We used to save all settings to registry for user settings, servername, size and locations.so we are now saving them into My.Settings app.config the only problem is that each time there is an update clickonce will isntall the newupdate but now all settings are loist and user has to save everything all over again..
I am trying to follow the book here but it seems i keep getting stuck somewhere. registry has worked fine for years but i understand we must move on, but if stuff like this happens then i just wasted a long time converting all code to conform for it to not work..

Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.

i have created a user setting named 'setmeup' as string, scope = user, value = "magical meow meow!".in my code i access it and assign it a new value like this...my.settings.setmeup = "howdy cowboy!"my.settings.save()application.restart()when the application restarts, i expect the my.settings.setmeup = "howdy cowboy!" but when i check its contents its still "magical meow meow!".but when i use application.exit() instead of application.restart() and manually restart the program, my.settings.setmeup = "howdy cowboy!" which is correct.what must i do? i want to use application.restart() because i don't want the users to double-click the icon again to start the program. i want the program to restart automatically.

1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...
2. I'm not actually saving them when I think I am.
Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?

I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.

I saw that you can also use a "Settings File" (Add new Item)to add your settings instead of the application settings. But I can't seem to write any values to the file. Someone with experience with the "Settings1.settings"?

I can double click on the Setting.settings and the projects Settings grid appears in design. I change the value of a user scope setting yet when I run the application in debug it picks up a value I set initially instead of the current value of the setting.
When the app starts I set a connection string to the path of the .SDF file that I set in the Settings.settings grid and accesss it with
mRootSDFPath As
String =
My.Settings.SDFConnectionString

it is possible to create dynamic settings using My.Settings.For example, a person clicks "Add User"The program then creates the settings for that user, it creates User(DYNAMICNUMBER)FN, and User(DYNAMICNUMBER)LN. Where Dynamic number is the next user for no conflicts in the settings. Is this possible? So that you can save multiple users for example?
