I am working on a migration project to convert a Visual Basic 6 system to a new platform. To make life easier for the programmers I would like to develop some plug-ins for the Microsoft Visual Basic 6 IDE. But until now I've found only information about using vb6 to write plug-ins for other programs. how to create a plug-in for the Microsoft Visual Basic 6 IDE (SP6)?
View 3 Repliesi want to implement in a program. I'm not asking for code just some advice and maybe a link or 3 to useful pages on the internet.I want to create a plugin system for an application that i want to make. The idea for the plugin system is based on the following...
1-Some graphics editing programs have what i think is called a filter/effects chain. its where you make a list of filters and settings that the program runs to edit the image.
2-In yahoo pipes you take small parts and use them to complete tasks for you mashup (like pulling all the images returned in a search and displaying them).
The system i want advice on is basically a plugin chain system modeled after these 2 idea's where the user selects plugin's and forms a chain out of them.for instance if i wanted to display a picture then i would form a chain of plugins like this
legend:[(inputs)what it does(outputs)]
[show open dialog plugin(output filepath)] -> [(filepath input)open picture plugin(output bitmap object)]->[(input bitmap object)Display a picture plugin(make a form for display)]
The code for the task's will of course be in the plugin's.The problem is i have never done any plugin system before. the hardest part i need help with is getting the plugin's loaded and sending the output's to each other. Also another problem i think is that the plugin's could be for anything (parsing text, displaying a picture, opening a url, downloading a file, etc, etc)Again I'm not asking for code just advice and some useful links to information.
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 found a lot of articles about Reflection and know how to create a class. I'm practicing how to work properly with the reflection to create a module/plugin-based application.So I found a simple example which is working great, but it isn't dynamic enough, 'cause it is hard-coded. I need to read all the .dll's from the application.startuppath & "modules" & *.dll and get there names (without the .dll).Code is was testing for practice returns the form (I know that this is not the correct way to call the dll dynamically):
vb.net
Imports System.Reflection Public Class Form1 Private Sub cmdOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdOK.Click Dim assemblylink As [Assembly] assemblylink = [Assembly].LoadFrom(Application.StartupPath & "/" & "LoginAssembly.dll") Dim LoginFrm As Form LoginFrm = assemblylink.CreateInstance("LoginAssembly.Login") LoginFrm.Show() End Sub

View 3 RepliesI need to write an app that that will iterate over our database, and perform various anaylsis on each record. In order to do this (partially for the learning exercise in creating plugin support) I want to use a Plugin model.
Currently, I have a simple Interface in my main app, which plugins can Implement. My app then loads all DLL's in a folder looking for ones implementing the Interface.
As you can see in the pseudo-code below, I have to keep performing a loop through all loaded plugins calling the process methods.
Sub ProcessData()
For Each Record In MyDataSet
For Each Plugin In MyPluginCollection

I am trying to make a plugin system in vb.net and i am using interfaces to do that. I have managed to implement the plugins but now i am having problems with setting the plugins in a dictionary or some sort of array.
The system is simple. I have the main application and i have plugins. The application needs 2 mandatory plugins and that is data and authentication. Other plugins are free to use so i have 3 interfaces. Data, Authentication and CustomPlugins.
I load the plugins with this
CODE:
It works fine like this but i want to make a collection of plugins because i don't know how many plugins the customer make. So initially i thought to make a collection
CODE:
But that doesn't work. The main focus is to load as many plugins as i like but have then in some sort of array. A dictionary would be perfect but is not a must.
I have a windows form application in which I'm attempting to utilize a plugin (class library). In the code I have it load the assembly from a dll file, which means I have not been able to debug. Furthermore I have not found out how to compile the library so I've had to use the debuged dll version for testing. I've run into a bug in which I create a new object and send that data through an interface to the plugin in an attempt to retrieve a blank slate group box from the plugin. However instead of reading the parameter as a new object i managed to step through the code once (don't ask me how, I don't know and I haven't been able to repeat it) and it appeared that the code was registering the parameter as "nothing" thus why I received a null reference error in the main program.
View 2 Repliesve been exploring with IThumbnailProvider in VB10. The first attempt I made was to handle MKV file thumbnails. I made the library and everything looked OK when I tested it against MS's Thumbnail app that came in the Windows API pack. Then I attempted to implement it on my computer, and every single thumbnail in the OS broke. Not a single thumbnail was generated by the system. So, after a bunch of trying to rescue thumbnails, I reformatted, reinstalled Windows, and got everything back to normal.
Today, I tried again. This time, using BLP files which are often used in Blizzard games (Warcraft III in particular). To avoid the same issue, I threw the compiled result into a Virtual Machine and tested it there, and it looked lovely. After a bit of experimenting and tweaking, I got it exactly as I wanted, cleaned the thumbnail cache, tested it one last time, and then installed it on my actual PC. Bam, all thumbnail generation is broken again.
I recently set up a Redmine server for my time. Redmine's Wiki uses CodeRay for syntax highlighting. However, most of my team prefers to code in VB.NET, which CodeRay doesn't support.Are there any plugins out there that offer syntax highlighting for VB.NET in CodeRay? If not in CodeRay, maybe through some other library (that could be integrated into Redmine)?

I would like to know if it's possible to create a microsoft word plugin via visual basic that when activated from a visual basic application did the following:
Creates a word document with a pre-made template Connects to an access (or MS SQL) Database Obtain ID from the application from which it was called The fieds related to the ID provided are filled in the spaces where they should go Show the document for it to be inspected by the user who initiated the request
That's pretty much it, I have no clue on how word plugins are made through visual basic... I've created the visual basic application that's inteneded to communicate with the plugin. So, could you help me find some good tutorials, tips or a place to start?
I'm working on a project where I'm experimenting with building and implementing plugins. I have a structure called "sensor" in the plugin that contains several elements. I would like to be able to return that structure to my main program through the interface, but it doesn't work. The plugin works fine if I'm passing strings or other variable types, but when I switch from strings to my structure, I get a couple of errors. On my main form where I try to call the function, I get the error 'value of type iMyPlugin.sensor cannot be converted to frmMain.sensor'. In the plugin code, I get the error 'GetSensorReading cannot implement GetSensorReading because there is no matching function on the interface'. Is what I want to do possible, or is there a better way to do what I want?

I have developed an application with a plugin architecture using interfaces. I realized that when I release the API for 3rd party plugin development, someone would be able to create a loader program to replace my main program quite easily. Is there any way I can make the plugin dependent on my main program? All my main program does is get an icon and a description of the plugin from the DLL plugin (using the interface) and then calls the dll's interface function to create and display the form.

View 1 Replies[URL]. Attached is a MEF WPF and WinForms project that I have been playing around with. I was able to add two 'plug-in' buttons to the form but how do I provide functionality to the buttons? How can I add objects from a separate assembly, like most plug-ins do? Let's say I want to break out each menu (File, Edit, View, Tools) into their own assemblies, leaving the main application window as a blank form that will import each assembly on startup. Also, could functionality from the Edit menu assembly interact with the code from the File menu assembly? I have also not created custom user controls before so as you can see I am having trouble creating a plug-in menu structure.
View 10 RepliesI was wondering if you could point me in the right direction as far as developing a super simple plugin for MS Project (both 2007, which uses the old style ribbon, and 2010 which uses the new ribbon). What I need to implement: create an executable that installs a new button, with a specific icon, in some per-determined section of the ribbon
when the user presses the button MS project needs to save a file in a specific format and location and then call a batch file.
that's it - pretty basic, right? Turns out, I know nothing about this space - so apologies in advance for how trivial this may be. Note: I'm not tied to a specific language - whatever is simpler / faster will do. BTW, does anyone sell components like this one? I don't necessarily need to code this if there's decent stuff out there for sale.
