How can I access data that WebBroswer1.navigate function is downloading from a website, while it is downloading it? If I access it once it has finished downloading it through the WebBrowser1_DocumentCompleted function, it only slows down my program, since it has to wait for the website to finish downloading to the control before I can access it.

View 3 RepliesI have been trying to use the WebBrowser control to access a website, nothing fancy involved, just a Security Certificate error message I can't get around:
The site that I've been trying to access is [URL].. By clicking on the "Login" hyperlink you are taken to a https connection.Internet Explorer simply allows you to click on the "Continue to this website (not recommended)" link which displays the Logon screen.Clicking on the same link in a WebBrowser control simply reloads the page as (I assume) WebBrowser has not been told that the page is ok.
I've tried looking around for the solution with no luck, it seems like such a simple problem..

View 2 RepliesI have a question about the webbrowser control that I hope someone can answer. I am working on a document retrieval and storing class that uses HTML to display and save data. I want to use the webbrowser control in winforms using VB.Net. I only want to store the fields values in the html document, not the whole document. I am hoping to use labels in html and read them with the DOM of the web browser control but am not sure how to do this.
Has anyone done this before and could someone please provide some sample code on how to do this?
I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.

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.

View 6 RepliesI 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?

I have created a program using FaxServer and FaxDocument. I want to know if there is a way to determine programically if the modem is busy? Busy in terms of it could be sending/receiving a fax or another program is using it. I just need to know if its in use.
View 5 RepliesI have a client program I wrote that waits for TCP communications. I found that when it was waiting, the form became unusable. I did some reading and learned about threading. Now it works great. Now I came to the point where I need to stop the program.. this is basically what I have:
[code]...
I figured I'd use the quit option to set the bool to false that the thread will see then do the proper closeout. However, it doesn't seem to work. After banging my head against the code, hehe, I realized that the thread is hung waiting for a client on the "AcceptTcpClient()" line.. so it's never getting a chance to evaluate SystemRunning.Is that an accurate assumption of the problem? If so, how does one deal with it?Also, I surmised that I probably should put my "end" statement at the end of the thread to be closed rather than my quit sub. I was afraid the marker boolean for the thread would get set and then the quit sub would immediately trigger "end" before the thread had a chance to close out. Is that also correct, or doesn't it matter?
I wrote a fax program that is using Microsoft FaxServer and FaxDocument on a windows 7 machine. I want to be able to check if the modem that the FaxServer is using is busy. I maybe busy for whatever reason (in use by another program, receiving or sending faxes, whatever). What currently happens, is if the modem is busy, the fax is sent to the Windows Queue and waits for the modem to get done. I don't want that to happen. So before sending I want to check if the modem is in use. I have a couple of things I have already done. But I am having issue tying them together.
I can get a list of ports for the computer and I can get the faxserver devices. But I would like to be able to do something like... take the faxserver device it is using(Com1, Com2, Com3...Whatever) and I want to check if it is free.

View 1 RepliesI have a form with several buttons on it and when the user presses one of the buttons it begins a lengthy process (takes up to several seconds). What I want to happen is that any subsequent button presses that occur on any other button on the form are ignored until the process is complete from the initial button press. What actually happens is that subsequent button presses go into a queue and are executed in sequence as the processes for each complete. What I mean is, if each button executes a function that takes 2 seconds and I hit 5 buttons very quickly (in less than 2 seconds say) it leads to a sequence of events that takes 10 seconds.... what I want to happen is for it to lead to only the FIRST button press occurring and taking the 2 seconds that it's activated function takes.
I am writing software that interfaces with hardware through a USB to UART converter and am using virtual COM ports and timing is critical. I want something to occur ONLY when I press a button, not seconds later after being queued up and waiting for a previous operation to finish.
I am trying to determine if a modem is busy. I have tried using serial ports which from what i can see just tells me that something is tied to a port or not. It does not tell me if the modem is busy.
My overall question is How do can I determine if a modem is busy? For an added bonus, also is there a way to tell what device is using a particullar port?
