I have a webbrowser control on a form and try to navigate to one specific site. It seems to me that the remote detects that call is from a desktop program and redirect it. Is it possible? and if it is how I can hide it.

ok so i have a PANEL control under a WINDOWS MEDIA PLAYER control. Both are same size.
The panel has a click event which shows a message saying "HI"
when the panel is behind the wmp control the message is not shown when i click on it.
so the question is is there a way round it, cos currently it only works if the panel is on top of the wmp control

just now I was trying to capture the F1 key on the form, but only managed when the form is selected, and I need to detect it in any form control. I used this code:
Select Case e.KeyCode
Case Keys.F1
MsgBox("Right")
e.Handled = True
End Select

I do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.
This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.

I'm trying to handle browser popups using the NewWindow event of the WebBrowser control. The one main thing I needed is the cookie from the main browser control on my form to be passed to the popup window. Below is the only way I've been able to open the popup and pass the Document.Window.Opener value to it so that when java script is executed, it knows where the opener window is. I am getting the following error right now when trying to set the cookie from my webbrowser control to the iexplore instance of the popup window that opened.

First off I hope I'm in the right forum.I have an application I built with the WebBrowser control in Visual Basic 2005. I am using the DocumentComplete event to track when a page has fully finished loading as some of the webpages I need to work with have frames.
The problem I am having is that when some iframes time out or don't load, the documentcomplete events stop firing. So if my webpage has 2 frames on it, we'd expect 3 documentcomplete events. One for each frame and one for the parent document once the frames have loaded. If say frame 2 does not load properly, the documentcomplete event for the overall document never fires.

Tried to look for a solution for this problem everywhere and can't seem to find it?I have found solutions related to sub-classing the document, but this method results in a Null Exception as there is no document.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AddHandler Me.WebBrowser1.Document.ContextMenuShowing, AddressOf WebContextMenuShowing
WebBrowser1.ContextMenu.Dispose()
WebBrowser1.ContextMenu.Show(WebBrowser1, pas)
End Sub

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms
Public Class form1

I'm using a custom webbrowser to display a special intranet for my company.I need to be able to display a custom keyboard whenever the user can type in the webbrowser. So if they click on a textbox within the page to type, this custom keyboard appears.when the user is in 'typing mode'. I thought maybe checking when the cursor changes to 'ibeam' which is the typing cursor? How might I do that, or is there an easier way?

I have an application that loads a web page then allows the user to edit that page by setting the Webbrowser control to EditMode.What I am trying, so far unsuccessfully, to do is trap when a user right clicks on a link already on the web page. The problem I have is that although I can trap the right click using MouseDown and GetElementFromPoint, if the link that is clicked is nested within a higher level element then the higher level element is returned by GetElementFromPoint not the nested element.[code]When the user right clicks, say, the link with test2.html my current code returns the DIV element not the A element. How can I understand which of the A elements the user clicked.[code]

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 have roughly 20 text boxes on my form,When you press tab, it naturally selects all text in the box (highlighted in blue), so you can press any key, and it replaces it with that,That result is what I want, unfortunately, if you click into the text box, and tab back to it, it no longer selects all the text.I'm wondering how I can detect the tab event properly,I've tried adding a 'KeyDown' event to each text box, and then selecting the text, but the sub never runs, also tried detecting the tab event in my Main Form, thinking that perhaps the parent handles it and will receive that event, but.. No.I've thought of using an event like 'Activated' however, it will also run when the mouse is clicked.

I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.

I'm trying to detect the insertion of a USB-Serial COM port device. I found an example that shows how to detect a new USB device - and that part is now working well in my project. The question is, how do I pass on that event back to my Form1 class? In the example, I can create a MsgBox just fine, but if I try to manipulate any of the controls on my form, or raise a user-defined event, I get this message: 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

My application has a form which contains several Textboxes where user is required to fill up data. Once data is filled up user can click on "Save" button to save the data. I have added lost focus events to all textboxes so as to validate user input. When I click on cancel button, i want to detect cancel button click, but textbox lost focus is fired first so I get error message for textbox before my code moves to cancel button click handler. Is there any way to detect button click before lost focus event?
