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 have programmed a web browser with Visual Basic 2010 Express and came across a major bug. Whenever I try to click a checkbox on a certain website, this error message appears:
An error has occurred in the script on this page.
Line: 193
Char: 9
Code: 0
URL: [URL]
Do you want to continue running scripts on this page?
[Yes] [No]
After clicking yes or no it just pops up again and I have to open the Task Manager just to close the browser.
I am facing a problem where i couldnt able to fix it. Could anyone help me on this issue.

I'm trying to prevent a sub / function from firing multiple times on the same event.My app is for handling inbound phone calls (tapi).The app is supposed to route calls based on the callerid number.
aircode below:
Code:
Private Sub OnNewCall(ByVal sender As Object, ByVal e As NewCallEventArgs) Handles tapiManager.NewCall
if newcall.callerid = "5551001" then
redirect(newcall)
[code]....
If callA.callerid = "5551001" then redirect(callA)but, once it is redirected to the new extension, do not then grab the call from the new extension and try to redirect again (resulting in infinite loop).I realize I could use an integer as a counter, but the problem is, I might actually get more than 1 call at the same time from the same callerid number. And, all the calls would need to be redirected (once).the calls do have properties like (which are unique identifiers to each call):
Code:
phcall.id and phcall.hashcode
I'm thinking I need to put that unique id into a temp var / array to run a check against to see if it has been redirected, if it has then skip, if it has not then redirect.The app would run 24x7, and I don't want the temp var / array to get too big, and would want to have it clean automatically (up on a timer maybe?)(I'm guessing it would be a dynamically growing array.)

View 1 RepliesI have a Devexpress Gridview that is linked to a delete, fetch and update stored procedure. The problem I am having is that when I run my program, select a row in the grid and press delete it fires the event multiple times. Specifically it deletes the selected row and then I re-fetch the data so the focus returns to the first row. Which is what I want.
Unfortunately it starts at the beginning of my list and goes down it row by row deleting each row it comes to. It then continues several more times after the rows are deleted. I know this because for each deleted row it asks me if I want to delete it. If I say no then the rows appear to disappear until I manually refresh it after the deleting is done. To make this even more random the second row always reappears after I manually refresh the grid.

I am trying to wait for the webbrowsers page to have finished loading to then carry out the next part of my code.However i am having problems because the DocumentCompleted event fires twice?
View 9 RepliesThis is a good way to use DocumentCompleted using AddHandler (good for a tabbed web browser) [code] Of course,.you can adapt this for a tabbed WebBrowser by replacing me.text with tabcontrol1.SelectedTab.Text.

I currently have two subs in Webbrowser3.DocumentCompleted. The first sub scrolls the web page to a specific point. The second sub takes a screenshot of the webbrowser window.Problem: Screenshot image is recording the top edge of the webbrowser. This means it is not scrolling to the right position before snapping the screenshot.
My guess is that the web page is not fully loaded when DocumentCompleted is called. Or the scroll is not being completed til after the screenshot has been taken. Result: After this is run, I end up with an image of the top edge of the browser. The Webbrowser is scrolled to the right place, but the image is taken before it gets there.

View 7 RepliesI'm using a webBrowser control as a simple HTML editor & I'm trying to stop the default action of creating a new <p> (paragraph) element every time you hit the enter key while typing text into the control.
I have added a handler for the keyDown event & I can insert a break tag, but nothing I do seems to be able to stop the webBrowser from continuing to process the event.
As you can see in the code I tried setting the e.BubbleEvent to false to stop the event.
The added event handler works just fine & executes before the webBrowser processes the event, but setting the e.BubbleEvent=False (or true) has no effect.[code]...

I have this code to attach a new navigating event to a custom webbrowser control. Here it is:[code..]
I do not know what is happening here, as I have used this code on previous projects before.
I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

I have a webbrowser control (in fact, a control inheriting from webbrowser), and added a tooltip control to the main form. Then, I filled the webbrowser tooltip text.But the tooltip never shows. (because the web browsers manage mouse hover with html?)I examined all the events exposed on the webbrowser control, and there is not one about mouse hover.so, the question is: How do I show the tooltip? Should investigate HTML, or there is a .NET control way?

I am trying to trap the newwindow event for the webbrowser control using this code
Private Sub wbMain_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles wbMain.NewWindow
Dim wb As WebBrowser = DirectCast(sender, WebBrowser)
Dim link As HtmlElement = wb.Document.ActiveElement
[Code] .....
But the href property is always empty, this is because the active element is the last button clicked. But it is a button I click in the webbrowser control that opens a link in IE.
I'm making a webbrowser that automatically refreshes till a link changes, then it makes some procedures.
I know that refresh methods dont fire the documentcomplete event so what could be a solution for my situation?
I have a web site that I want to check for a html link modification, for that I need to refresh it every 30 seconds.
