Does anyone else get a noise from the WebBrowser whenever you load a page? Internet Explorer does this too and I want to turn it off. Does anyone know how to silence this?

View 3 RepliesI have a web browser control, what I use is:
Ret = (MainBrowser.ReadyState <> WebBrowserReadyState.Complete Or MainBrowser.IsBusy)
If ret is true, not loaded, otherwise, loaded. It works fine on winxp, however, on vista, most times, it works, sometimes, not. Do I have to use documentcomplete for this? The page is loaded from another thread, does it matter?
I have a few subs that run under Webbrowser1.document completed section of my app I know the code words because I tried it out using a new project and tied the code to a button and it works great. After stepping into my code during run time it appears that the app is trying to call my sub before the next page appears. What would be the way to place a pause on the Thread so that the web page can catch up before running the next sub?
View 3 RepliesI am trying to add two features to my webbrowser: View Source and Find. Does anyone know how to get the webpages source code and a method to perform a search in the webpage? I was thinking one might lead to the other.
View 1 RepliesI'm working on a pretty simple project, just a WebBrowser app which is tailored for Webmail. I'm working on an OWA portion, and OWA normally doesn't allow the textfields on the Login page to be auto-filled. Is there a way I can force this? Search through the OWA login page code, find the fields, then fill in the fields with preset/saved data?
View 6 RepliesWe are using a web browser to show a pdf file located in a folder on the network. The code looks like this:
System.Windows.Forms.WebBrowser.Navigate(New Uri("\hostpath ofile.pdf"))
This works fine, but now I have to use a specific user to access this file and I don't know how to include the user name, password and domain in the URI. Is it posible to add user credentials to the URI? Can I use another variant of Navigate method to accomplish this?
Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.
View 16 RepliesI have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.
I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.
When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.
[Code]...
IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.

If user uses quotes (Examples: Linux "in" mobile phone), then noise word is not removed. What is best way the handle this.
As the the Title suggest's i want to make an alert noise, such as a simple beep, play after a timer has expired. I have the timer working, just dont know the function for making a noise?
View 3 RepliesI am looking into programming an application that detects noise levels. If the level is over a specific threshold it will lock a logged on user account. The idea behind this application is to reduce noise levels in a busy IT suite. My question is has anyone written anything similar and did it prove to be effective and is VB the best programming language for the job?
View 1 RepliesI am a newbie (retired social worker) using Visual Basic 2010 Express edition and need some help with an animation for an eLearning lesson. The animation illustrates a type of white noise (like TV static) called dynamic visual noise. I've got much of the code worked out (with a lot of help) but I discovered that the speed of the animation, using this code is wrong and need some help to fix the code, get it working correctly.You can view a Flash demo of this noise animation at url...More info here about the visual noise animation (even a Delphi source code and Windows demo): url..The animation has a 640 X 640 canvas, with 8 X 8 white and black dots filling it using 80 across and 80 down, for a total of 6400 dots. Some of these (approximately 400) change every second (1000 Ms) from white to black or black to white. These 400 dots need to be selected randomly every second.
The VB code I am using is missing the ability to randomly select the 400 dots per second which are the dots to be changed (white to black or black to white).Here is the current (commented) code that needs an addition of a random generator for the 400 dots every second that will be changed:[code]It would also be a huge help if I can change the specific number of random dots so I can try values ranging from 390-400 dots per second to see which value best replicates the precise animation speed needed.
I've been trying to get some help for this in another thread,but it looks like it's a task that is going to need a wider audience to try and find someone who knows something about writing/creating procedural textures at the pixel level in VB.Net. The VB6 example I'm trying to convert to VB.Net is attached to this post.

I am creating basic slideshow form to finish off an app I am writing. I have been at it all day finishing off the main app and am getting very tired now!!

View 9 RepliesI have a program which opens up a webpage through a WebBrowser object in c#, and does a bunch of operations with it. Now I need to integrate this functionality into my own webpage.
That means that either I need to take the c# code, and somehow make it work in my webpage itself (put in a WebBrowser object, set up event handlers, etc), or I need to somehow have my webpage open this program on my server, fire an event to start, and receive input from it. It is very important for me to use a WebBrowser object (or even WebKit.Net) because there is a lot of javascript, etc on the page that needs to be processed.
