I have a program that autologs itself into facebook and monitors posts to my main page and tells me if anything new comes up. Every minute my program refreshes the page and searches for a new post, if my session is expired it logs itselft back in automatically. If I'm in explorer trying to play farmville and my facebook monitor program is running then I'm forced to log in about every minute because my login at the browser kills my vb.net program session.
Then my vb.net program logs itself back in and I'm out! This behavior doesn't happen If I have two browsers running I can log into both and it doesn't seem to effect the other. I can even have my wife log in from another machine while I'm logged in and It's ok. So The question is why is useing the webbrowser controls in the Vb program any different then just having 2 open and logged in browsers and jumping between the two.

My code editing program, with text colouring and lots more, is almost finished. It uses a rich text box to edit in.On the right is a listbox, called the "suggestion box" The suggestion listbox is kinda large and eats up lots of valuable edit space How can I display my "suggestion listbox" control underneath the caret, like in Visual Basic?

even Word Pad, when you scroll your Caret (the I-beam for browsing through text) through the text, in the font combobox, the font of the text you are browsing through will be displayed, and when you scroll your caret through a different font, the font will be changed. If you're confused, look at attatched picture.
I cannot seem to find a caret position changed event on the normal richtextbox control - and if anyone can show me a custom component with this it would help me a huge amount.So my basic question is how can i replicate the formentioned function in my own VB.NET program.No code is necessary just constructive suggestions, or links to other projects would be welcome.

I was wondering if it is possible to allow the add-ons that were developed for IE to work with webbrowser control.
I am working on a browser that uses the webbrowser control. I need to add certain features like ad-block to it. I noticed that these features are available as add-ons already for IE. Since webbrowser control is IE-based, I was wondering if it was possible to enable the webbrowser control to access these add-ons?

I need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.

I'm trying to find a way to reproduce the FolderBrowserDialog control functionality but not in a dialog. I'm been looking around for a good part of today for solutions but with very little progress. I found a few writeups on listing folders and their contents in a treeView but nothing about listing everything including "My Computer", "Desktop", etc. This seems like something that would've been built right in to Visual Studio. I'm working with VS 2005.

Im currently working on a project which included a webbrowser navigating to a website. Whenever it arrives there it disables me to double click on the Media Player inside the website to go full screen. Although I know this is possible as Ive seen that the webbrowser can disable clicking on Firefox. My question: is it possible to enable the standard webbrowser in Vb.Net to allow me clicking even if the website doesnt.

I want to create a User-Control that inherits the functionality of a TabContol.
I begin by starting a new project of the type Windows Form Control Library. Next I place a TabControl on the UserControl designer surface and Dock the TabContol to Fill the UserControl.
I go to the code editor for the UserControl and enter the following line of code.
Inherits System.Windows.Form.TabControl
Then I run the program and get an error. Intellisence recommends that I use one of two recomendation. When I accept the recommendation I and try to run the program the problems esculate.
The design-surface is no longer accessable.
I try to comment out the problem lines of code in the UserControl1.Designer.VB file but that doesn't help.
How can I create a UserControl that Inherits the Properties of the TabControl so that the properties of the TabControl are visable in the Properties Window?

Code is written below

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.

I moved this from the debugger thread as I got no responses.This may be a better area.I have a problem enabling a Scrollbar on a custom control I have created.The custom control has one component,the scrollbar and an area that I draw upon from an internal datasource.Think something like a textbox.In certain instances,I want the scrollbar to be enabled. The Custom Control's job is to do this when the situtation is appropriate.I have a very simple piece of code here:
If <logic conditions> Then
DataScroll_vscrollbar.Enabled = False
Else[code].....
This code is in my OnPaint routine (along with a bunch of other drawing related stuff).Essentially I've determined that there is more stuff to display than the area of the control and need to turn on the scrollbar to give the user of the control the ability to see later stuff.With the exception of this funny behavior, the control is doing exactly what I want.I step through this and have a watch set.I can step through the set to True, but the Enabled value doesn't change.Even the EnabledChanged event fires (Doesn't on the set to False because it's already False), but the Enabled value is still False.I don't know why.Now here is the really interesting part and may give somebody an idea about what's happening: I can change the Enabled value via the debugger (via the Watch) to True.The EventChanged will fire, and from that point on I can set the Enabled value to either True or False and back again with no problems.
I even did some really crazy testing to see if perhaps the debugger just wasn't showing something.
did something like:
Dim idiot as boolean = false
if <logic> then
idiot = true[code]....
I have set the values to Minimum and Maximum, but the problem remains.

I want to enable the 'ReaderMode' for paning/scrolling my control in .Net. Closest thing I found was this Win API function .url....However, I'm not sure how to call this one, in the documentation it says, This function is not declared in any public header. To use it, you must access it as ordinal 383 from Comctl32.dll.I've never called a function that didn't have a name before, can anyone describe how to do this in VB.Net?

Is there a way to set the enabled property of a combo box using the tab index?
In my program I have two combo boxes next to eachother. When a certain option is selected in the first combo box, I want the second to enable itself. Obviously this is easy to do by using combobox2.enabled = true but I have 10 rows of boxes that need to do this and I want to put all the functionality into one sub. It's possible to read the tabindex into a variable by using VAR = sender.tabindex and then add 10 to that variable (The box that needs to be enabled will always have a tab index of sender + 10) but I can't figure out how I'd use the tab index to enable it. If only I could just type sender.tabindex(+10).enabled = true

I have a usercontrol that contains a datagridview and a toolstrip. When creating a windows form that contains 2 of the mentioned usercontrol i gate for example c1 and c2 where both contains for sure the datagridview and the toolstrip hving the same control name for example G and t. in my case i want to apply the security on each form, i do this by reading the access of each control inside the windows form and if the control on the form was a user control then i dont consider it as one entity instead but as a grid alone and a toolstrip alone in order to be able to apply its security accordingly. but in ma case, if i want to disable the first grid and enable the 2nd i wont be able to do so since both grids have the same name. is there any solution for the above.
