i am working on a auto click program and it is working well apart from it goes slow because im using a web browser to visit the websites.
I heard i can use http request to vist websites ?
Im just using
WebBrowser1.Navigate(url)
Is there anyway i can edit that so it does a http request to (url) rather than get the web browser to go there ?
i have a program that uses a web browser to view the users website in side a proxy.But of course web browsers are slow so would like to change to http request. [ code] To go to the url and the url is stored in (url)Is there any way i can change it to http request ?

I have a server making a head request to a database dump I've created. The remote server does this to make sure that it's not using excessive bandwidth when not necessary.However, due to some other circumstances outside my control this causes the script to be hit twice: once for the head request, and then another time to download the data.
What I'd like is to have the script I've written detect the head request, send back a couple of headers (e.g. last modified is right now, filesize different than before), and exit. Is there a way to do this?

View 1 RepliesIn VB.Net, how do I make a program to tap into the HTTP requests made by external web browsers? I don't want to edit or stop the headers, only 'read' them, i.e., access its contents. I'm speaking of something like Fiddler2, but I only want the 'reading' part. I also want to read the user-agent.
View 1 RepliesI'm looking for some advice on how to optimise the following process:App reads csv file.For each line in the file an XML message is created Each XML message is posted to a URL via a HTTPWebRequest This process was designed to handle low volumes of messages (up to about 200 at a time), un suprisingly thinks have changed and it is now expected to handle up to about 3000 at a time.
The code used to post the message is here: Public Function PostXml(ByVal XML As String) As HttpStatusCode

I am currently restricted to sending multiple messages due to restrictions elsewhere in the system. There is a noticable delay in responding to the request at the other end (the receiver) but this is outside my control. I am trying to ensure that the process of sending is as efficient as possible (external factors notwithstanding).
What I'm trying to achieve is something similar to an Add-on called Live Http Headers used with Firefox. I'm not trying to get the Headers or cookies, but the links that load on the page itself. Let us assume I visited Mail.Yahoo.com, this is pretty much what you would see when I use the add-on.

I am currently working on a personal project with hopes of using VB.NET 2008 to connect to my personal forum for use of both authentications into the program and group changes. People in my forum are based on ranks, the ranks are organized via the groups in the forum so if one person gains a rank they need to be taken out of one group and placed into another. With multiple people this is a process and presents a security risk should someone get kicked out but accidently be left in a group giving them access.
For the time being, I need to be able to post the headers to the forum to login and parse the response. I have tried many times and I�m currently trying this using the chilkat dll as a reference which allows me to send headers and see the response, but the response is always the failure to login page. The headers are as follows:

View 11 RepliesI have created a few months ago a simple tool in vb.net, that sends an xml code to server, and that server sends response after a while. Everything is performed in http session, for that purpose I use webbrowser control and webclient. I know it could have been solved in different way, however iam not an expert in vb.net, and also didnt want to spend too much time on it. Anyway it worked, until they had changed something on the server. Let me explain in a few words how that tool works, so it will be easier to understand the problem.
In the first part, I open an URL in the webbrowser control, subsequently I enter xml code in the textarea on that page and click on the submit button. In result of that I get another page with some data on it, namely links to xls files. In the next part I use webclient for downloading those files. What is important for all of these operations I need to use the same http session id.
So, simply by now, i just set headers in webclient - WebClient.Headers.Add("Cookie", WebBrowser1.Document.Cookie.ToString) What have guaranteed to use the same session id by the WebClient. However, after the change made on the server mentioned before, the JSESSIONID value is not available in that string. When I use https analyzer (fiddler), I can see that value there...until moment when I am using WebClient. Of course due to that fact, the webclient won't download files for me, because the session id is not the same.
There is one more thing, what would be useful. When I checked the cookies file on my harddrive, I saw that line starts like #HTTP_ONLY. I think that would cause that problem with jsessionid.
Now, I am coming to my question Do you have any idea, how I would get that JSESSIONID value ? It is sent from webbrowser control, however don't know how to get it.
I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.
Header 1
Item 1_1
Item 1_2
[code]....
I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.

View 3 RepliesI'm wanting to write a program in vb .net that could monitor outgoing print requests from any program on the PC, prompt the user if they would like to add a header to the document, and if they say yes, then tack it on (if the user has printed something in the space where the header will go, just print on top of it). Is this possible? I've looked around for ideas on how to do this, but I can't seem to find anything.
View 1 Repliesthis is general to any operation calling an SQL server, or anything requiring an open connection at that.
Say I have anywhere from 20 to 1000 Select calls to make for each item in data being looped. For each step, I'll select from sql, store data locally in a struct, then proceed. This is not a very expensive call, so should I keep the connection open for the entire loop? Or should I open and close every step?
How expensive in run time is opening a connection? I would think it'd be better to keep the connection open, but would like to get the correct response for this.

My winforms application is consuming webservices that run on an older PHP server, which is why i often get an XML parsing error from the service class when i invoke its members.
how do I get to see the faulty XML so that I may correct it on the PHP server - the thrown exception clearly states the position of the error in the XML, but it doesn't help without the XML.
