I've an application that's uploading data to a server. Occasionally the server returns a 403 response from a call to HttpWebRequest.GetRequestStream(). The response contains more data than simply the response code, but I can't figure out how to access it. Is there a way to do this?
View 2 RepliesI have a small program which is a tcp client. I send a string from this client to a device over ethernet (it acts as the tcp server). As soon as the device recieves the input string it will respond back with response data. My problem is i am not getting the entire response data back from the server. (device).
Dim serverStream As NetworkStream = clientSocket2.GetStream()
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("my-cmd")
serverStream.Write(outStream, 0, outStream.Length)

Background information: I am simply using Fiddler2 to monitor my HTTP connections.
When I am posting data, there is no actual post data. The data I enter into the web page is only in the hex view or the raw data. How can I send a request using raw data or whatever method with a webrequest?
I'm trying to get data from a webservice, returning just one result, the number of a given item in stock.
I'm successfully getting a result, but need to strip all the XML code from it to simple return the number, the XML being returned looks like:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
[Code]....
With just a couple of tweaks to get the data correctly, most notably changing the content type to application/soap+xml and passing the data as XML.
I am using VB with ASP.NET 2.0.
This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?
Is there any other way to access a serial port using visual basic.net 2010? I followed the steps in this site, [URL] but I just got this output Open the serial port. Send the attention command to the modem. Wait for data to come back to the serial port... and stopped there. I can't get the Read the OK response data in the serial port. Close the serial port. And I was thinking, because it is very much easy to access serial port in vb6, so can I just use vb6 and then connect to visual basic.net? it is like a language inside a language.

So I'm a little rusty on my VB.NET skills, but I decided to take up a project to get me working in it again. Problem is I've hit a slight road block and I was hoping someone here might be able to point me in the right direction.I have a spreadsheet (or 3, but they could be combined if that makes it easier) that contain interest rates. I need my program to use user-input to select which interest rate it needs and then calculate and output the grand total, without the end user ever seeing or even being aware of the interest rate table.

Is it possible to add, edit, view and delete records using a file only (instead of a database) and .Net 2005 (VB.Net/C#)? The concept is that a file that'll work more-or-less like a database. One can add, edit, view, delete and query data to and from the file. The file, either cannot be opened directly or data inside the file should be in some encrypted form so that even if the file is opened no one can comprehend it. Data inside the file can only be manipulated by a front end application i.e. .Net 2005.

View 4 RepliesI'm using VB 2005 Express Edition.I'm trying to use VB to do a few things, the first of which is to display the data behind the registry key at;

AudioSrv

This shows no errors initially, but complains about not being able to convert "string()" to "string" once I run it. I'm assuming this is because the data I want is a line of string entries, but I can't find a solution.FYI, this is a project I'm working on to heal a Conficker attack at work. Our third party support has stopped the spread and healed the servers, but has now left me with the job of doing a 3 minute registry fix on each of our 400 computers, hence the attempt to automate it!

View 1 RepliesNew to VB.net, and trying to re-factor an 'old-skool' ASP page where all the page logic is happening on the .aspx page itself, to code-behind. Basically, I have a button that has a state, either on or off. If on, I set a hidden field to 1, if off, I set it to 0 (the default when a user visits the page).The goal is to simply change the message I am sending to the user.[code]The above code produces the following effect: when I click the button, setting the state to 1 and the page reloads, in Page_Load, I am getting zero results from the If dlList.Items.Count > 0 Then check, and thus am showing the 'No results' message, but the actual asp:DataList on the MyPage.aspx page is returning results... and then if I click the button again, setting it back to 0, in Page_Load, the datalist is now returning results, so I set the text to 'Results', but again, the control on the MyPage.aspx page behaves correctly, and shows no results, as expected. Now keep in mind that the above works perfectly in terms of checking the number of results if I move the If dlList.Items.Count > 0 Then page logic out of Page_Load and back to the MyPage.aspx file, it all works fine (i.e. results when state = 1, none when state = 0)
