I am posting to a website to get data back. The site returns it as an xml. I am able to get the data into a string. But what i really want to do is to have each item in the xml in a different string field.
[Code]...
I want to be able to split these fields and set them to different text boxes on the page.
I am trying to build an application that will return a responce from a url containing an CGI "get" or "set" instruction. Example : Http:192.168.1.56:...in/get?exposure This is the syntax that would be entered into any web browser to solicit the IP camera for the current exposure value.
What I am trying to do is build an application that will allow these responces to be placed into a TextBox. Conversly I want to place values into a text box and submit the new value. Example: Http:192.168.1.56:...set?exposure=10
I want to post the textbox1 strings into the &username in the php textbox and also to post the textbox2 strings into the &password in the php textbox then click the submit button.
Here it is the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show("Please enter your username")

When you search on google most of the examples are very vague, hopefully this thread can make it to the top and will help someone looking for the same info.to explain the code what it does is create a long string by concatenating all the values together stores it in the variable finalString and then hashes the string using the SHA5 algorithm. Then its supposed to send the string (finalString) as a post request to the url.The server im sending it to reads it this way and sends a response. [code]
View 1 RepliesI'm trying to port an old VB.NET application to an Android application, but due to my lack of Java experience I am unable to find this one out. I have tried multiple solutions but to no avail.The idea is basically to do a POST request to 'url...' and getting the response cookies.[code]

I want to read a HTTP Post that comes from a server to a website. I am trying to write a script that basically parse the HTTP post that comes in as text format and read the variables in the text file then add them to a database.
I know how to do the second part but I am unsure about how to read the text file variables that comes from the HTTP Post
The HTTP post that get sent looks as below
CODE:

I am trying to write a code for this and have the code below

I just want to parse simple expressions like IIF(FVAL(PFC) = TRUE, (IIF((ORGVAL(BAS, "2012/12/31") + ORGVAL(DA)) < 6500, (FVAL(BAS) + FVAL(DA)) * 12%, 780)), 0)`After parsing this I should be able to know what functions contains what parameters.
[Code]...
I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.

I need help with something it drives me nuts. I have an application which send XML to a web server through a POST method. This part works excellent. But where I have issues is with receiving the standard response from the web server for OK or error. Instead of receiving the actual response, I get the error message" WebException was unhandled. The server committed a protocol violation. Section=ResponseStatusLine" . The response I should receive is in XML format where I have as elements the error result (ok or error), the error number and the error description. Here is the code I have:

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'm using Response.AppendHeader("Refresh", "2; url=default.aspx") To send users back to the home page after they log in or log out and it works. But, on the contact us page it fails and this is what it says: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.Requested URL: /default.aspx, 2; url=default.aspx The weird thing is this doesn't happen in debug, only on the live site. It looks like it's appending the header twice somehow...

Using VB 2008 .NET 3.5..I am working on an N-Layer desktop application.Suppose a method in the BLL runs into an situation where the user needs to be notified and the method needs to wait for the user input (OK, Cancel, etc.) before continuing.Assume that this situation happens fairly often but not all the time, and is expected. It doesn't seem correct to throw an exception. The only solution I have so far is to raise an event with a custom EventArgs, and allow the UI to set some property in the custom EventArgs to reflect the user input.

I'm creating a small program in Visual Basic, using Visual Studio 2010, which communicates with a GSM modem via serial port.The connection works, I can even communicate properly with the modem and I can also send sms and mms .. But I can not handle the modem answers ... I'll explain:If I send a command like AT + CSQ modem replies with + CSQ 22.0. This command gives me the value of the signal as a response on a scale of 0-30 ... I can see on the screen (in a dedicated console) but I would like to manage the response in the sense that I would do something like that
IF (answer.text = "+CSQ 22,0") Then
label1.text = "Good"
ELSE
label1.text = "Bad"

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?
If you run this code, builder.Append("Content length: " & response.ContentLength & _" bytes" & vbCrLf)
it returns a string builder object which shows the number of bytes contained in the page. But the url here must exceed some sort of character limit because it is returning -1 as the value which means (Unknown?)
