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.
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.
View 1 RepliesIn an other post of mine, a discussion was going on to change the extensions of mdb so user does not recognize it as Access DB (this is important for me) I tried this and changed extension to xrd, ran the application and it gave error. Off course it could not find my mdb. How to handle this? Do I need to make all the connections again?

.a00 ,.a01...................,.a19.
Also there is application called apk emulator which can open .apk files. So eve I want to design an application that an open certain file extensions. Is it possible? How do I start? I am well versed with c, c++, Java, VB.NET
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.
View 3 RepliesI want to use C# and VB.Net in Eclipse 3.7 Indigo.VB.netI could not find the plugin about VB.net in Eclipse.So I want to know is there a plugin for Eclipse that allows you to write C# or VB.net code using the .Net Framework 4.0 or 3.5?
View 1 RepliesI 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?
I cant make a seekbar control using a windowmediaplayer and vlc plugins
View 1 RepliesWhile 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...
View 2 Replieshow 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 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?

I can open the extension manager and browse all the extensions, but as soon as i click the "Download" button to install it, i get this error;
"The extension could not be installed because the following error occured:
The remote server returned an error: (404) Not Found."
when you use the object browser to see the features of a sortedlist elementat is not shown , but because a sorted list inherets features of ienumerable it works, cant that be corrected

What if you do not know where your program will be, and you are just testing it for now? Is there any way for it to "find" your program, or an easy way to edit where it is opened? For that matter, is it possible to tell if the file has been associated already, is it an issue to try and reassociate? Finally, how can you set the .ico file it uses?
