Stop Webbrowser Objects From Stealing Focus If Auto-refresh Header Is In Use?
Jul 12, 2010I have a VB.net form which has two webpages embedded. The webpages have a 5 second auto refresh built into the HTML header as the information is constantly changing.
The problem I have is when I pull up a secondary form, I lose focus to the 'Main' form everytime the webpage refreshes.
Is there any way to stop the webpages autorefreshing in the form and I will build in a refresh command into a timer I already have in place and then I can start and stop the refresh at will.
Unfortunatly I cannot amend the source code of the HTML as this is required for a different process elsewhere.
Manipulating Data On An Active Form With Objects
Sep 10, 2011this is not really a code issue, more of an events issue with objects. I want to be able to generate an output as the user inputs into each text box under the "further invoice details" section. For example, if the user inputs a value to amountrequired text box. Then a gross total is auto generated without the need to click a button.

How To Make Webbrowser Refresh
Dec 26, 2010I am writing an ap that monitors a website for changes. The website is for reserving campsites and I need to know when they change the date we can book a reservation. The date can change at midnight or any time during the day. It is completely random.I start the program launching a webbrowser with the URL. I have an inputboxbutton that prompts for the text to track for change. You paste the text in there and then the ap is supposed to wait for x minutes then refresh.I have a refresh button that works perfectly. Here is the code for it:

Webbrowser Timing And Refresh?
Nov 17, 2009I am a complete noob at programming, so I need all the help I can get with my new program.I am building a web-browser which is linked to one webpage. The content of this page is constantly changing, so I need the web-browser to auto-refresh after 2 minutes. But if it refreshes while NOT connected to the Internet, the browser will show an error message, so that is why I have build in an Internet check. This check is working. The browser also have to be in the same place at the screen every time the software is loaded. This code is also working.
But the timer and the refresh is bugging me. I cannot get it to work. The code is not responding.

Oct 8, 2009I want to make a program in Visual Studio 2008 in Visual Basic. It involves a web browser and I want to make it auto refresh and allow people to choose the time period in which they want to auto refresh.

If I am mistaken, please correct me and tell me how to do this.
View 1 Replies.net - Webbrowser Control Does Not Refresh Htmltext
Feb 6, 2012I am developing a google maps ap, and want to refresh the map with new detail on demand. The initial problem offcourse was that the webbrowser control does not reflect the changes (still keeps the original htmltext) and new document text and refresh. I understand the document text is set once, and cant be changed... apparently.
I have tried
navigate("about:blank")
document.stop
document.new(true)
doevents
All the collected user knowledge on this problem, only get me half way. I can get the page refreshed using some of the techniques above, but it then gives me a script error and an error 53, which both has no details or origins.. just blank errors.... after clicking through their error windows, my page refreshes.P.S. I don't know if my javascript events that are bound to the webbrowser control causes the errors. Some have suggested that the errors are due to the document loading without all its references being closed/open...
.net - WebBrowser.Refresh - Navigate Backwards
Apr 20, 2009I'm working on a webcrawler in VB.net, and using the System.Forms.WebBrowser object for handling navigation on sites that use javascript or form posts, but I'm having a problem. When I navigate backwards (WebBrowser.GoBack()) to a page that was loaded with a form post, the page has expired and I have to do a refresh to resend the request. When I call a refresh (WebBrowser.Refresh()), a dialog box pops up to confirm. Is there a way I can get around this modal dialog in code?

View 4 RepliesPrevent Refresh Of The WebBrowser Control?
Mar 12, 2012There is PreviewKeyDown but I don't know how to prevent it from passing the keypress to the browser using that method & WebBrowserShortcutsEnabled will disable them but not allow other stuff like Control+C,Control+V and even the delete key in a textbox wont function as well as technically any F keys will not be passed to the flash I have running in the web browser control so the reason for disabling was made moot because the keys still aren't usable in the flash game either because they don't function at all anymore or it has an action already(F5-refresh)How do I disable it without stopping it from being used by the underlying webpage - flash in this example....
Return returns execution to it so it ends up calling keydown like normal, there is no actual keydown event for the webbrowser control or id use that....I cant block navigation because a refresh appears to not call any of the navigation stuff....End stops execution of the whole program it seems, not just stopping that part of code in its tracks...Stop just pauses the program in the debugger....Exit has the same result as return does....
Is there no way to either use PreviewKeyDown to not return execution to the caller....or maybe some kind of await procedure(visual Studio 2011 & its await procedures/async procedures) or something which will never finish... them using it a lot(the F5 key) wont use a lot of cpu while it waits for something that would never happen....Or just any other method which could make this work how I need it....

Making An Application That Uses Multiple WebBrowser Controls And Multiple Proxies?
Dec 17, 2009I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.

View 1 RepliesVS 2010 Keeping Track Of 'Active' Tabpage With Multiple TabControls?
Aug 11, 2010I am building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.
I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.
The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.
The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.
At the moment, I am doing this:
- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:
vb.net
Public Shadows Property SelectedTab As Tab
Get
Return DirectCast(MyBase.SelectedTab, Tab)
[code]....
However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.
So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...
Forms :: Handling Events From WebBrowser Objects Contained In An ArrayList?
Jul 18, 2009I'm writing a tabbed web browser for someone who is learning VB.NET, and I have got to the point where I can add/remove browser controls into tab pages, controlled by one set of buttons on the main form, but I can't handle events from the WebBrowser objects.I have tried this but it says that 'DocumentTitleChanged' isnt an event of 'Control'...
Dim browser As New ArrayList
browser.Add(New WebBrowser)
browser(0).parent = TabControl1.SelectedTab
browser(0).dock = DockStyle.Fill
AddHandler browser(0).DocumentTitleChanged, TitleChangedHandler()
I want to update the tab title with the web page title when it changes. I started using a timer to update the tabs but there must be a way to add an event handler here.

it looks like it may work...but is there a way to automate it so that i can put in a reference to ANY radiobutton like radiobutton(*).text? or a bunch of buttons if need be.i know theres a way to specify additional items to a given command...just can't remember if its curly brakets etc.
.net - Get INotifyPropertyChanged On Multiple Inherited Objects?
Sep 2, 2011I have a class, Vehicle. I created two child classes, Car and Plane. I want to monitor the speed, which is a Vehicle Property, and bind it to a control (label, or image, for example) in WPF. When i create a static Class which only purpose is watching the Speed Property, it works, as far as the INotifyPropertyChanged is declared with the Speed Property name.
But the problem is, I have to create dynamicly multiple Cars and Planes by looking in an XML file and deserializing my objects, and creating multiple Car or Plane UserControl (Let's not discuss this way of working, please). So I have to get the Speed property inside the Vehicle Class (which is normal), and I have to get a INotifyPropertyChanged on each Speed of each Vehicle Created. So, my Cars and Planes are loaded, and I have to get all speeds, but I can't create a static Speed property by Vehicle. By the way, by creating a non-static Speed property (as int, for example) in Vehicle Class with INotifyPropertyChanged raised in the setter, it does not work. The event seems to be raised, but my converter is not fired, and my controls does not update.
In my Vehicle Class
Private SpeedValue As Integer
<XmlIgnore()>
Public Property Speed() As Short
Get
[Code]....
The PlaneView Class is almost the same for this part.
I confirm that the converter is fired just once, the first time, when the tabs are created, because I put a breakpoint on the Convert function definition. After that, the converter is never fired again. So the picture img_fonctionnement is displayed, but it is never updated. But the Speed property is updated, I swear. And the INotifyPropertyChanged (in Speed's setter) is raised, as far as i know with the help of the debugger.
And the "an item with the same key has already been added" (which appears in a messageBox, and not as an exception) seems to appear only when I am to long with the debugger. In normal execution mode, it never shows.
