This sort of code is almost always improved by dropping the picture boxes and instead writing your own code to put the images on your form, where you want them.

Webrequest and Querystring in VB.net

25-Jun-09 21:46

yes, of course it's possible. Most encryption/decryption uses standard known algorithms. So you need to find an algorithm that you have an implimentation of in perl and in VB, or you need to write one.

your subject line is ridiculous. Everyone here wants help. Try putting something that means something.

I am very new to web development and i am finding difficulty with webrequest and querystring in vb.net.
I am working on an application which will pull data from a URL. The data will come with 2 variables. "from" and "text" that is the sender of the data and the text of the data.
I have a desktop apllication which is supposed to read this data from the url and i am pretty lost here.

how do i use webrequest and/or querystring to read the data from the url and pick the two variables.
for instance i want to read them like this

Dim message_originator As String = context.request.querystring("from")
Dim message As String = context.request.querystring("text")

I don really know what to do to read them as above into the variables.
Any help please guys? Confused | :confused:

How is the web request getting into a winforms app ?

king gamo25-Jun-09 18:54

25-Jun-09 18:54

i use the following to get it but i don think its right.

<
Public Sub GetNewMsg()
Dim sOutput As String
Dim sURL As String = "http://www.something.com/noticeboard"
Try
Dim objNewRequest As WebRequest = HttpWebRequest.Create(sURL)
Dim objResponse As WebResponse = objNewRequest.GetResponse

Dim objStream As New StreamReader(objResponse.GetResponseStream())
sOutput = objStream.ReadToEnd()

Dim message_originator As String = context.request.querystring("from")
Dim message As String = context.request.querystring("text")

'place code to read specific string token you need here
'for example code to insert into database etc. just see what you have in the
'string if fetch was successful and then you'll know how to readi specific string

Catch eUFE As UriFormatException
sOutput = "Error in URL Format: [" & sURL & "]" & NewLine() & eUFE.Message
Catch eWEB As WebException
sOutput = "Error With Web Request: " & NewLine() & eWEB.Message
Catch e As Exception
sOutput = e.ToString
Finally
MessageBox.Show(sOutput)
End Try

End Sub

You're doing a post to a URL and looking for the query string on the response ? That sounds weird to me. Any change of URL is a new request/response, I'd have thought.

Christian,
I am really lost in what i am doing. Please if u can help me out with retrieving from the url where i can access the query string, i will be able to continue from there.
thanks

Christian Graus25-Jun-09 19:49

25-Jun-09 19:49

I honestly don't think this is possible. There's nothing on the query string when you send it, so I don't expect there will ever be a querystring on the response. I think you're barking up the wrong tree.

king gamo25-Jun-09 19:51

25-Jun-09 19:51

please so how do i go about retrieving the data from the url then from my winforms app?

The only data on the URL, is the data you put there. This is the core issue here, which is why I said you're totally lost. What makes you think the URL will change when the data is posted back to you ?

Sounds like you are confused about request and response. You get query string only when you are getting a request. Assume you are writing a HTTP server and someone requesting to your program with query string, you will get it. In your case, you are the one who is requesting and you only get a response which won't have query strings. You will get the output of the URL you requested.

Or did I got your question wrong? Smile | :)

You got my question right. Now my problem is how do i get the data from the url? the winforms app has to read from the url whenever data is pushed there by a sender.

It is not who i am underneath but what i do that defines me!

Christian Graus25-Jun-09 20:05

25-Jun-09 20:05

We're both saying the same thing. The URL will not change, so there will be no query string data. Have you run this through the debugger ? The URL does not change, between a request and a response, which is what your code does.

Thanks guys i get u but is there a different way i can use to achieve what i want to do please.
Ok a remote server will be posting data to the url for me to read. I have setup the url like http://www.myownserver.com/noticeboard
They will be pushing the data here for me to use. I dont know when the data will be available but i know the variables. 2 variables will be available for me, one for the sender and the other the text named "from","text".
Is there a way out. If its impossible then i think i have to go crazy now cos i really need to do this.
Is there any other way in vb that i can use or it is not possible in vb.net?

VB.NET has nothing to do with it. If you wrote the site, then push the data you want back, inside the page. Or better yet, ditch this rubbish and write a web service.

A remote user will request a URL with some query strings. Then the page will generate some data. Now you want to get this data in your windows application. You don't know what query string he used. You don't know when user is requesting that page.

Is that what you are trying to do? If yes, it is impossible.

All you can do is to persist the query strings used in a database or somewhere else. Your windows application can look this DB frequently to see any new data available. If new data is there, take the query strings and send a request to the URL for getting response.

Try Using VB.NET to Decode PDU string[^]

If that is no good for goodness sake use Google or Bing or something searching on sms to mobile vb.net generated a shedload of hits.

Sir!!
I have readed this site including many other.

http://www.developershome.com/sms/howToSendSMSFromPC.asp

Now acting on instructions one by one.

I reached on the line

"Here is a description of what is done in the above example:

Line 1: "AT" is sent to the GSM / GPRS modem to test the connection. The GSM / GPRS modem sends back the result code "OK" (line 2), which means the connection between the HyperTerminal program and the GSM / GPRS modem works fine.""

when I did this step then I got 'ok'.

But next 13 steps giving me error....

after line 13 (on that page)

it is written there

"To send SMS messages from an application, you have to write the source code for connecting to and sending AT commands to the mobile phone or GSM/GPRS modem, just like what a terminal program does. You can write the source code in C, C++, Java, Visual Basic, Delphi or other programming ."'

In this paragraph I didn't get the point( you have to write the source code for connecting to and sending AT commands to the mobile phone ).
To understand this I have googled again, but all in vain Frown | :(

Now please help me .. After alot of search I did came here. So I am following the terms and conditions I think Laugh | :laugh:

Ok, so what don't you get? You have to write a program that communicates with your mobile device to send SMS messages. Do you know VB.Net? Are you sure you can handle a project of the size and complexity?
