Use IE Plug-ins / Add-ons With Webbrowser Control?
Mar 10, 2011
I 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.

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 writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.

Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

I'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.

I'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.)

I 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]...

I have a webbrowser control, where I show images (bmp files, that the program creates), and I want to add some UserControls to setup the images (as showing layers, or choosing colors to display). Is easy to do appropiate UserControls on VB.NET, and I know almost nothing about HTML, so, I would like to add standard VB.NET UserControls near the images.

Even when i debug my own code, i'd find it a useful feature.In c++ this feature is default in visual studio(its called browse-something), but i havent found any such thing for VB.NET yet, any ideas?

I want to send On and Off Signals to a USB Cord Connected to my Laptop.Universal Serial Bus, right? In my IDE, I have put a SerialPort Object onto my form. But I don't know how to detect or how to find out at what port number the USB 2.0 Cord is connected to? I wanna start working with Motors and Stepper Mototos with VB.NET. But I fear I am not smart enough to mess with it. I have done many different things with VB.NET, I wans to start messing with Serial Ports, and Serial Communication. It Says COM1, a USB Cord Connected to my laptop is not a COM1.

I'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?

I'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?
I am using Visual Studio 2010 Ultimate and Running Windows 7 Ultimate with all Service Packs and updates applied.

So I've got a button that adds a tab using the tabcontrol object.
TabControl1.TabPages.Add("Test")
How would I add a webbrowser to that since i dont know what the tab page # of it will be specifically?
Each tab will have the same components, but might goto a different url.
