Dec 9, 2010
I am using a webbrowser control in my form, and i have simple php pages that does a post back to itself to get some data, the php page is on my server, and navigated to by the webbrowser control.This process sometimes can take 5-30 minutes.Ive noticed for some people waiting 25 min. the browser will come back with "page has timed out"..i can try it on my machine and it works fine..Its worked find in a XP - IE8 and WIN7 IE8 and Chrome machine.Ive seen it not work on XP IE8, and Vista IE8..Actually take that back, it wont work now on my WIN7 X64 after about 5 min.If i bring back the query quick, it works, its just the longs runs..

I cannot tell you how disappointed I am in the vb.net Web Browser Control. It really seems very ill thought out and rushed.So; to my question! I have searched all over the place in an attempt to find the answer to this and from what I can see alot of individuals are suggesting that it is better to use the old web browser control from VB6. However, i'd like to try to avoid this.

I have some questions about the Windows.Forms.WebBrowser control.I have added this control to my project to be able to browse websites internally.First problem is that when I come into a webpage that contains JavaScript to open a new window, the control opens a new instance of iexplore.exe, tries to load the page in which the java script popup code initiated, but then prompts for authentication for a second time.Basically, I have to sign into one page to get to a listing of applications.I click on the application which in turn is just a URL to another page.The URL to the other page contains java script to open a new window.The new window opens in an iexplore.exe process, but re-directs me to the original sign in window instead of taking me to the correct site.If I do a msgbox on the cookie that is currently loaded, it displays my authentication information.How do I tell the new iexplore.exe processes to use the cookie that was stored in the webbrowser control?

I created a function to check if my webbrowser control is completed loading, however, it dosent seem to "wait" until its webbrowser is done loading the page.
While WebBrowser1.ReadyState <> WebBrowserReadyState.Complete
Application.DoEvents()
End While
I want to check if 2 or even 3 browsers are completely done loading, so i even had something like this.
While WebBrowser1.ReadyState <> WebBrowserReadyState.Complete or WebBrowser2.ReadyState <> WebBrowserReadyState.Complete or WebBrowser3.ReadyState <> WebBrowserReadyState.Complete
Application.DoEvents()
End While

So, I'm trying to make a spiffy little program that lets you search for flash games, and it will automatically display the flash game within the program. (by writing document text to a webbrowser control) Unfortunately, the site I use to get the games from uses iFrames from Custom Google Search to house the search results. I know how to deal with frames in a webbrowser (WebBrowser1.document.window.frames("frame name here").document.so on and so forth), however it seems as though iFrames are different. When I try
WebBrowser1.document.window.frames("googleSearchFrame")
, it doesn't recognize that it's there. Same thing if I replace the name with the index of the frame - it's not there. Using

An action that I'm trying to automatically complete on a web page requires me to click "Yes" on a JavaScript alert box. Obviously the entire process cannot be automated unless the program clicks "Yes" or "No" for the user. Is there any way that I can capture this alert box and click "Yes" programmatically?

I wanted to know if there is a way to stop my webbrowser control from steeling my cursors focus? i mean its bad enough i have to hear the god damn thing in the background as it refreshes the pages.
What i built is basically a program that checks my marks on my school website and verifies to see if any new grades have been added. The program then notifies me by sending a text message to my phone. The program is in its beta stage and has lots of sloppy logic and code. anyways i hope someone knows how to keep my focus from running off of msn when I'm trying to type.
And as for the variables and coding. i know i have made it sloppy with unnecessary variables. I'm planning on cleaning that up when i have the time.

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.

I'd like to integrate Webkit.NET into a VB project, but I'm not having any luck so far. The Webkit.NET tutorial page gives a demonstration in C#, so I assume that it's possible to use this in VB.NET as well? [URL]
I added the control to the project successfully, but since I'm not familiar with C#, I haven't been able to convert the code successfully (even after running the code through a few different online C# to VB.NET converters). So... has anyone gotten Webkit.NET (or any Webkit-based browser) to work in VB.NET? Or am I just dreaming? I would love to be able to use the default .NET WebBrowser control for this project, but this project requires doing a few things that the IE browser is not capable of (but Webkit can do it easily).

Okay so here's the question how do I get the links that open in a new window to open in my main webbrowser control. The above code does some, but it's not fool proof.

Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?

I was running VS2008 express and WinXP and everything was working great. I'm now running VS2010 Express and Win7 x64
My issue is that I am running a webbrowser control that is loading a page with scripts and I get a "Out of memory at line xxxx" and the page wont finish. I've tried it on XP and it works fine so it is a Win7 issue. I call it by the standard, wb.navigate("link.com") and it errors out. If I do a "process.start("link.com") it opens a new window and works great. If I open IE or firefox standalone, everything works great. It has something to do with my webbrowser so my question is how/why is the webbrowser different than the standard IE webbrowser?
I would try to load a new IE window, but I don't know how to pull and push data to a webbrowser outside of my app. My app does form manipulation in website to streamline manual processes for filling forms out.

I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?
