I 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. It won't take user input but I have checkboxes that are preset. I think this may be possible using a timer and the WebBrowser1.Refresh() method. If I am mistaken, please correct me and tell me how to do this.
View 1 RepliesI want to know how to autorefresh a vb2008 form having a webpage (cricket scorecard), form must refresh in 5 sec.
View 3 RepliesI 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.
I 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...
I have two webbrowser controls in my application, and I need them to refresh every so often, for example, every 5 minutes. How do I do that?
View 4 RepliesThere 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....
I need my webbroswer control to autoscroll down and over to a certain portion of the page when the page loads. How do I do that?
View 3 RepliesI have been working on this one for a couple of days now. The company I work for wants me to automate a login (coupled with a phone dialer) to a national Satellite retailer. When the call center individual gets a call the ACD system forwards them to a URL and is supposed to log them in. Unfortunately one of the sites heavily uses frames and I cannot programmatically autofill the userid and password and programmatically press the "OK" button on thee website. The website is: [URL]. I have been able to drill down and fill in the userid and password fields, but this has stopped working but I have never been able to Invoke the OK button event.

View 4 RepliesI am in a situation where I have a tool which is always running.

View 5 RepliesI have a web reference listed on my windows form and I have it listed on my form.VB page "Imports ......" with my intellisense turned on. Everytime I start to type something my visual studio would stop working as I am guessing it is trying to refresh the list with all the commands from the web service I added which takes a couple of minutes. How do I set it so that it will not refresh the web reference? I want to be able to do it manually only, I want my intellisense to stay as it has all the commands I needed in there.

View 6 Repliesi am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]
I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.
Public Sub InsertRow(ByVal param1 As String, ByVal param2 As String, ByVal param3 As String)
Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)
[code]....
After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.
there are two computer connect to one shared database one of the user (user1) will insert new record then the records in (datagridview) of the user (user1) who insert the record will be 11 record but the(datagridview) of other user (user2) will still have 10 record.what the possible way that may allow me to refresh the records..Also how I can make a new record in datagridview of the user2 can be colored by yellow or red back color.
View 2 RepliesI have an issue that I can't seem to tackle. Going on 3 weeks. I have a VB.NET app with an sqlce 3.5 database. I have created several tables in this database. I have attached them to my form using DataSet then BindingSets and so forth. Done this many time before. VS automatically created a TableAdapterManager for me.I was having an issue getting the Refresh of the primary key value of a newly inserted row. Ok, find out that sqlce does not do big transaction, or multiples rows at a time, found Beth Massi's blog on how to work around this:Ok, got it somewhat to work, but I had to take one of the tables out of the tableadaptermanager so I can update it by itself so insted of doing this:
frmMain.Validate()
frmMain.bsRunInformation.EndEdit()
frmMain.TableAdapterManager1.UpdateAll(frmMain.DS1)

View 3 RepliesI 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:
Private Sub Button_Refresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_Refresh.Click
WebBrowser1.Refresh()

I 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.

I'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?

Is there anything that i can do to code it to FORCE refresh the browser every 5 seconds?

I know that autosize works with a form's property, but I'm trying to autosize a webbrowser.
I've tried this:
Dim Rect As Rectangle = Me.WebBrowser1.Document.Body.ScrollRectangle
Dim BodySize As New Size(Rect.Width, Rect.Height)
Me.WebBrowser1.Size = BodySize
Unfortunatly it didn't work.
I also tried this:
Me.WebBrowser1.Document = AutoSize
But it obviousely won't let me. I also tried to dock it to the bottom of the form, but it isn't exactly what I want.
I use webbrowser as File Explorer.
If you click folder it opens new folder contents in WB window but if you click html document it opens in EXTERNAL viewer.
How do you get html document to open in WB while exploring ?
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.
