I'd like to be able to set a HttpWebRequest to read teh contents of a text file located on a website (ive seen it done, they use a webrequest and set it to a string, but i can't find it anymore o.O)
View 3 RepliesI have a login form and what it does its uses datastream or webrequest and post's a url to a php file i have. If the login is true, it will return a 1, if it is a bad login, it will return 0. But my problem is that the acars wont read 1 or 0. it reads all of the html on the page. Is there anyway i can make it so it only displays a 1 or 0 to the acars, and not all the html of the page?

lets say webpage has 2 strings named sampleObj="sample1" and sampleObj="sample2" Even though sampleObj remains the same the text inside, however, changes.How would you loop inside page and get sampleObj text each time? I tried Regular Expressions and GetElementsByTagName but no luck.

But it doesn't work. the string I'm sending converts ok when I open the site + do the conversion manually, but using the above code it reports an error:

I've double checked + it must be a problem with the stringdata line.
I'm trying to get a string from a byte array previously read from memory
i can get the string like this
dim mem as string= ASCIIEncoding.ASCII.GetString(memory) or dim mem as string= UTF8Encoding.UTF8.GetString(memory) but when i try to concatenate this with another string i get a strange result dim result as string = "this is you memory string " & mem & " problem string" no matter what comes after mem in the concatenation it seems like it is not there when in fact it is because when i try this (mem has two chars in it) dim result as string = "this is you memory string " & mem(0) & mem(1) & " problem string" problem string appears so what i assume is that there are some vbCrLf chars in the string after reading (or is it from the conversion?)

View 2 RepliesI�ve had success using the GET method to retrieve a series of web pages but my new challenge requires me to use a POST > GET combo. I can get it to work once just fine but no more. I get the feeling that something isn�t closing or completing properly. When I try to do the second GetRequestStream() I can see from my sniffer app that nothing is being sent so when the next command to stream the POST data to the request session it fails. I removed it all from the loop and simplified it as much as possible. Can someone tell me why it fails?
Also as a general question is my tack or reusing WebRequests viable? Or is there a �best practice� for looping a POST > GET combo? I�ve been assuming that since nothing in the WebRequest changes besides the post data I�m sending, even its length remains the same, that I should be able to re-use it.
Dim Cookie As New CookieContainer
Dim encoding As New UTF8Encoding
Dim byteData As Byte()

Note: The section after the �Experimental comment is a surrogate for the second iteration of the loop. The GET that normally follows the POST section has been removed.
How do I check if httpwebrequest is doing what it needs to do?
Since theres no webbrowser involved your kind of left in the dark and cant actually see if what you programmed worked.
I'm trying to send some data onto a server. The data is an XML in form of string and and image encoded to base64.The problem is that the server says '404 Not Found', just as if I had an incorrect URL, but my URL is 100% correct. I can get data from the server using GET, but when I try to POST it doesn't work.I checked it in Fiddler and it first gets z 401 error (not logged in) and then the 404 error, which results in an exception.Can anybody please have a look at the below code and tell me if there is something I'm doing wrong?

I am using a System.Net.HttpWebRequest class to download source-codes from a website, in an ASP .NET application.
The problem is however, that the ASP .NET server hosting my application is located in the United States. This means that when the application downloads source-codes of a specific page, the page being downloaded thinks that it needs to send the United States version of the page itself.
I need that to be customizable.
here is a quick example

I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).
