Jul 1, 2011How 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 using the following code to upload a file to web space that I own and and has all access rights, however for some reason even though it looks like it should work and there are no errors the file is never created on the server.

Dim sw As System.IO.StreamWriter

i have a weird problem: when i use httpwebrequest to download a string from a site, it says 403 forbidden, but when i try to acces the same string from any browser, everything goes normalcode to download string:

Is it possible to obtain these input elements during an httpwebrequest without having to view the html code?
I�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 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.
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
vb
Dim linkd As String = "http://abc.com/file/tk/asdfasdfasdfasdf./me.avi" req = WebRequest.Create(linkd) req.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.8) Gecko/20100625 Firefox/3.6.8"
but when i debug i found that httpwebrequest calling

It works fine for GET requests, but when I try a POST, it errors: Quote:
A first chance exception of type 'System.NullReferenceException' occurred in WindowsApplication1.exe
Request Error: Object reference not set to an instance of an object.
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)

this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

i am trying to get this code that worked in VB6 just fine to work in VB.net 2008. It doesnt seem to want to connect (but has no error after it goes past the sockMain.Connect().

In this case GDI no longer stands for Graphic Device Interface! I have an MDI form, and the child form loads up with a single panel positioned at a specific spot so that i can have a visual studio styled menu on the left side. The square white area is the panel with the fields in it for the user to enter. The left side is a TreeView with GDI lines drawn around it that dont appear until the menu has been changed. Here's what the menu looks like when its rendered properly:
When the form first loads, you can quickly see the GDI drawings come up (sometimes) then disappear. It flashes pretty quick when you can actually see it, but until you change the menu item to another causing it to redraw, its just... gone.. Looks like this:Here's the setup:I have two labels docked at the top for the large white text with a black background
There's the treeview on the left in a picturebox where the GDI components are drawn, and a panel touching it on the right side, which is sized and anchored on all sides basically keeping it stretched to the size of the window while keeping the top and left side pinned in position so it doesnt move, keep it touching the menu on the left.
Inside the panel is 10 more panels, one panel for each menu item. Each panel is programmatically set to resize to 1024x768 and becomes visible once the menu item for that panel is clicked. The panels are all programmatically top positioned at 0 and left positioned at -1 to hide the left border stroke from having the BorderStyle set to FixedSingle. Moving it to -1 hides only that border within the panel its in.
I have dual monitors, so i began stepping through the code on one monitor with the program running on the other so i could see what its doing with each step. While going through, at one point i see the contents of the TreeView completely vanish, but all the drawn GDI stuff is there. Once i get through everything and finally hit F8 on the very last line when control of the program is given back to me because its now waiting for me to do something, all of a sudden the treeview contents re-appear and the GDI drawings vanish.
I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.
I recently got microsoft expression studio and VS 2010..To test out expression, i created a sweet looking UI, and transferred an old program from VS 2008, but the CSV writing function I have written in the '08 doesn't work with my WPF form in '10.

Now the weird part is that it goes to the Else case, while the 2 variables in the If are the same.
