WebBrowserControl DocumentComplete Not Firing?
Jun 27, 2009
Program was working fine, now all of a sudden it decides it does not want to navigate for me...It doesn't appear that either of my DocumentComplete or DownloadComplete Events are being fired when navigating to a very minimal web page.I even tried deleting the code blocks, and "re-adding" them in the IDE. no dice.This is pretty much the most important part of the whole program. arggh.what could be causing this? I tested by placing a msgbox call in the Document Complete Event. no popup*

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.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser.Navigate("www.google.com")

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.

Upgraded OS from XP SP2 to Vista SP1, now the WebDisplay.DocumentComplete event will not fire. Running in debug mode in VS2003.App works in runtime, so why is IDE VB 2003 debug running on Vista SP1 not working? Worked in XP SP2.

I'm using the following code to create a bitmap from a webbrowsercontrol that is located just off-screen (not visible to user, but control is "visible") Does the CopyFromScreen method work for something that is not ACTUALLY displayed on the screen?
I checked the values of p.X and p.Y at runtime and they are correct, but my "img" does not reflect the portion of the "Screen" i'm trying to capture.
Not sure what I'm doing wrong here, or if CopyFromScreen will still work if my control is outside of the bounds of the primaryscreen.
vb.net
'This is set at FormShown time
'Position the browser off-screen
Dim wbPoint As New Point(Me.Location.X + Me.Width - 50, Me.Location.Y)

I coded a very small website bot in C# using the default WebBrowser control. Actually almost everything is working the way it is supposed to work, yet I seem to have problems with the very last step of my automation.
The website was built using several iframes. This isn't much of a big deal as I simply access those frames and their elements using
webBrowser1.Document.Window.Frames[0].Document.GetElementById("element").InvokeMember("click");
This however does not work when the source of the IFRAME is being hosted on a different domain than the actual website. As I searched the internet for an answer to my problem I stumbled across an MSDN article mentioning this specific problem and they were referring to safety measures against cross site scripting which might be the reason for this error.
I couldn't really find a way of disabling this feature so I moved on and decided to recode everything to work with geckofx-12 instead of the default (IE based) web browser control, yet I ran into similar issues...
My question is: Is there any way I can bypass this annoying behaviour? I don't really care about security concerns or on whether geckofx or the default web browser control is being used, I would just like to programmatically access the elements of a site which is being hosted on a different domain without running into an UnauthorizedAccessException.

I am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.

I have a WebBrowserControl on my main form and it auto navigates and all that just fine! What I would like to do is not allow the user to click anywhere within the WebBrowserControl while the program is running. Reason for this is that the browser self-navigates to a view of cameras and this shows scrollbars. My program then takes screenshots of specific coordinates on the screen so I do not want the user to use the scrollbars or highlight or do ANYTHING to the page once the program starts. I would like to change the cursor icon to like a red X or something similar to indicate no user functionality.

Here's the item from the View @Html.EditorFor(Function(model) model.BirthDate)
Here's the code from the EditorTemplate (simplified)
@ModelType Date?
<span>
@Html.TextBox("", Model)
</span>
[Code]...
Ok, so after some digging, I found that if I add <UIHint("Date")> to my BuddyClass, then the template works.
So my "new" question would be... why wouldn't it pick this up by default?

I am using a monthcalendar inside of a panel. when the user changes the "showweeknumbers" of the calendar I need to move some label to the right of the calendar, but I also need to resize the panel. The problem comes into play when the user hides the weeknumbers, the monthcalendar resize event fires and the labels move, but the panel resize causes the month calendar to fire the resize event again, making the labels all out of wack...

I have the following code:
Private Sub Exceptionquery()
Dim connection As System.Data.SqlClient.SqlConnection
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
[code]....
I get the error Invalid Object name 'Scratchpad3' on this line:
adapter.Fill(ds)
I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:
Exceptionquery()
I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.

I've been looking for a solution to this for several hours now and cannot find a solution.
The Scenario:I have a masterpage baseclass (called basemaster)All of my master pages inherit from basemaster
basemaster defines an event 'Public Event HandleClickEvent As EventHandler'I have a masterpage named master1
master1 defines an event handler 'Public Shadows Event HandleClickEvent As EventHandler'master1 has a user control named usr1 usr1 has a button that raises event ButtonClicked when clicked I have a page (thePage) that uses master1 thePage has a button click event handler that it registers like so: 'AddHandler Master.HandleClickEvent, AddressOf HandleTheClick' master1 has code something like:
Protected Sub Usr1_ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Usr1.ButtonClicked RaiseEvent HandleClickEvent(sender, e) End Sub when thePage loads I see it register the handler on master1 when the button is clicked, Usr1_ButtonClicked is fired and I step through the RaiseEvent but HandleClickEvent on thePage is never reached.

I am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.

The problem im having is a little complicated to explain, so please bear with me. I have 2 button controls. In the page load, I wanted to know what button created a postback on the page load. Through research I have found this snippet below and it works as expected. So here is my scenario of events that occur when click on the button.
1. Click the button does a postback
2. Runs the function below and tell me the id of the button
3. Runs the clicked event handlers for that button [code]
The problem comes in when I click the second button, it does steps 1 and 2 but NEVER DOES 3. Through testing, I have that it only does 1, 2, and 3 on the first button clicked.[code]
