Working On A Project That Is Based On Modules And Plug-ins?
Aug 24, 2011I'm working on a project that is based on modules and plug-ins. Any of these modules might alter some part of a database in various ways. One module might write or edit one table, while another module might write or edit other tables.
The modules all communicate via events raised on a common object. Therefore, when a person using module A enters a certain change that would edit data managed by module A, the module raises a Proposed Edit event such that all other modules that might be affected by the edit will have a chance to accept or reject the edit. If no module rejects the edit, then module A makes its changes and raises an Edit event, at which time all the other modules make any changes they need to make.
That's the basic pattern, but there's a problem. If I don't share a transaction during the edit, then module A can successfully edit their tables, but module B might fail to edit their table. In some cases, the failure by B should rollback the changes made by A. Therefore, it would make sense for module A to share an open transaction for all the other modules to use while making their changes, and this gets either committed or rolled back, depending on whether everyone was successful, or not.
The problem with that design is that a person could write a new module C that had a bug which caused it to fail to update correctly. That would cause it to signal that the transaction failed, such that all the other modules, which had been working up to that point, would no longer work because this new module kept canceling the transactions. In other words, the modularity of the program has now been lost. Every module depends entirely on every other module that even cares about its data.
In most cases, what would be lost if certain modules failed would be minor, whereas what would be lost if other modules failed would be catastrophic, as there would be no way to re-create the lost data with any kind of ease.As long as this explanation is, it may not be sufficient. At least it might start a discussion. Do the actions of all the modules act in the same transaction, or should they be left to succeed or fail on their own?

View 2 RepliesUse IE Plug-ins / Add-ons With Webbrowser Control?
Mar 10, 2011I have a Browser application written using the .NET webbrowser control. As I understand, the 'webbrowser' control is based on Internet Explorer.
So, I was wondering if it is possible to use the add-ons or plug-ins (like Adblock, IE7pro etc.) that were developed for Internet Explorer with the webbrowser control.
This will really save me a lot of time as many of these plug-ins provide the functionality that I am looking for and are freely available.

View 10 RepliesImplement The Player Class Through Plug-ins?
Mar 16, 2009I've never actually used Reflection, but I've been warned in the past that using it may cause slow performance. My question is what part(s) of it is/are slow.
I'm thinking about creating a board game and I wanted to implement the player class through plug-ins. That way there could be several different player classes (i.e. human players, and several configurable AI classes). If implemented this way, where should I expect performance hits? Only when initializing the player class? When passing arguments to methods in the player class? In the entirety of execution of methods from the player class? Or is it going to affect the whole application?
The reason I ask is that the AI will be extremely processor intensive. Through testing it seems like it may take around 1-30 seconds to determine a move on my quad core (Core 2 Q6600) processor, depending on the effort spent to optimize the move and testing different branches on separate threads.
My concern is that if I implement the AI via a plug-in, the move determination would slow down considerably to the point where it wasn't playable on lesser hardware.

View 9 RepliesWay Of Implementing A Plug-in Based System
Feb 18, 2011I've written a pretty good browser in vb.net (it's in the "Share your Project" forum). I now want to give users and other developers the ability to extend/add buttons & functions to it. Can anyone suggest to me a good way of implementing this bearing in mind that I've never tried to do anything like this before? (so basically a way of implementing a plug-in based system. I was planning on these being small snippets of code which my application has the ability to compile.)
View 5 RepliesWrite Firefox Plug-in Using Program?
Nov 25, 2009I have a VB.NET User Control (compiled in VS 2008 into a Class Library DLL that is COM interop enabled). This is embeded into a HTML page (using its GUID), is driven by Javascript method/property calls and sends feedback back to the HTML page using <script for="id" event="method()> tags. It was developed for (and works great in!) Internet Explorer.
I am now looking at the possibility of porting this VB.NET Class Library DLL to Gecko-based browsers such as firefox 3.5 based on customer demand. I've downloaded the Mozilla development code, but all the examples are in Visual C++ 6.0.
From what I understand from the Mozilla docs, I should be able to register a specific media type against my DLL (installed in the firefoxplugins directory) and, as long as it supports the correct interface/DLL methods, I should be able to use the object tag to embed in the same way as IE.
I don't mind having different web-pages for IE and Firefox but I don't really want to re-write the VB.NET control in Visual C++ and ideally I'd like to use the same code base for both.
I've googled but not found any examples so I'm guessing this is either hard or impossible! :
(1) Has anyone done this and has a hello world style example?
2) How would I code the VB.NET methods/classes so they appear the same as ones built using Visual C++ 6.0[code]...

View 1 RepliesAPI To Hide Non Plug And Play Devices In Device Manager?
Feb 24, 2012I'm writing a Windows Forms application in VB.Net 2010. The application's purpose is to recreate the Device Manager in VB.Net. The idea here is to capture the information provided by Device Manager and store it in a database. In turn this information could be used as a configuration management tool.
My device tree is coming along nicely, with one minor exception. There are hidden devices that Device Manager does not display by default. Show Hidden Devices causes Device Manager to display these devices. My Device Manager displays them by default. I want to duplicate the Device Manager behavior of being able to hide and display these devices in my appilcation. I have had some success with this task in that I am able to hide the Plug and Play devices that are marked as hidden by windows by use of the "Don't Display In DM" flag. There is the small issue of the Non Plug and Play Device Class. My question is this... Is there a similar flag for Non Plug and Play devices? I have found a reference to the PNP_DEVICE_STATE and IRP_MN_QUERY_PNP_DEVICE_STATE IRP. It contains a flag
PNP_DEVICE_DONT_DISPLAY_IN_UI. My problem is that I cannot find any guidance as to the structure of this API declare and the coding needed to use it. I'm not even sure if this API will be helpful in accomplishing my task. I want to hide the Non Plug and Play devices and device class in my tree. Can someone please assist me with the locating an API that will accomplish this and the proper coding of the API in VB?

View 1 RepliesCreate A Project That Contains A Pet Class?
Jun 21, 2010Create a project that contains a Pet class. Each object will contain pet name, animal type, breed and color. The form should contain text boxes to enter the information for the pets. A button or menu item should display the pet information on a separate form. Hint: Use a ReadOnly property on the input form to pass the object to the second form.
What I have done so far is create a new class with the name Pet and have instantiated each object with readonly property. I have also created another form where the information entered by the user will be displayed. Guess I kinda need to know what would be the next step? And I want to ensure what I have done so far is correct.
