Programatically Send and receive data using Post Method

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
Hi,I wish to make a script which programatically send the POST data to one server and then the other server receive the POST message and retrieve the information. How should make this work? I already successfully write the sender site, the code as follow:string postData = "id=0&co=5";ASCIIEncoding encode = new ASCIIEncoding();         //data encoding         byte[] dataEncode = encode.GetBytes(postData);         //end ascii encoding scheme         string url = "http://localhost:51711/Handler1.ashx"; //         //web request         HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);         req.Method = "POST";         req.ContentType = "application/x-www-form-urlencoded";         req.ContentLength = dataEncode.Length;         //send data                Stream st = req.GetRequestStream();         st.Write(dataEncode, 0, dataEncode.Length);         st.Close();ASCIIEncoding encode = new ASCIIEncoding();byte[] dataEncode = encode.GetBytes(postData);stri

Sys.Data.DataContext.saveChanges method doesn't send update to server after DataServiceException ex

Hello,I have a page with a simple form that updates a single record in a table in my database.The database is accessed via WCF Data Services. To load and save data from/to the server, I usethe Sys.Data.DataContext object provided by the ASP.NET AJAX library. When the "save" button on theform is clicked, I use the saveChanges method of the Sys.Data.DataContext object to send all changes to the server.Also, at the server side, I use an interceptor that checks the "Price" fields of the record, and throws a DataServiceException exception when the contents of the field is a negative number.Both the JavaScript and the interceptor (in C#) are copied below.Here is the interesting thing:When I enter a negative price in the form, the interceptor throws the exception and my form shows an error message. Good.However, if I then make one of the other fields in the form a bit shorter (for example from "abcd" to "abc"),the saveChanges method doesn't send the data to the server. But it does call the success callback that I passed in to saveChanges, creating the impressionthat the data has been saved. This happens while the Price field is still negative. I used Fiddler to make sure thatno message is sent to the server. Also, the interceptor doesn't get executed.The weird thing is that if I make one of the fields a bit longer instead (for example &q

Using HttpWebRequest to send POST data with parameters and a file

I have a form that has the following<form action="http://site" enctype="multipart/form-data" method="post"> <input type="hidden" name="action" value="the action" /> <input type="hidden" name="apiKey" value="key here" /> <input type="hidden" name="name" value="racing" /> <input type="hidden" name="title" value="Race Cars" /> <input type="hidden" name="signature" value="sig here" /> <input type="file" name="file" /> <input type="submit" name="_upload" value="Upload" /> </form>I know its not .net controls.. but hat doesn't matter for now, what I need to do is post this form with all it's data, but entirely in code.I have found this post: http://www.developmentnow.com/g/36_2005_3_0_0_300351/Using-HttpWebRequest-to-send-POST-data.htm this describes how to do it but I am not getting it.I will have a file upload on my page and a textbox for name and title, but the rest are generated in code.I know it's a long shot, but can anyone give me an example of exactly how I would do it for  my scenario? I have been at it all day and I am struggling! I keep getting bad gateway errors when

TCP Client/Server communication: NetworkStream.Write() send partial data unless close() method is re

Hi to all,
I wrote a simple client-server application that comunicate through NetworkStream class. The problems comes when stream.close() and client.close() methods are called. It look like only the first 10415 bytes are sent once those methods are called. So, if the data to send is more than this size, it is automatically truncated.

If I  remove both stream/client close() methods from the code, the data is fully received whatever the size is. I tried various alternative solutions (the ones marked as comments in the sample code), but none of them works.
The only thing that seems to work is adding a manual delay before the close() methods execute with something like that:

For Counter as integer = 0 to 10

The problem is that after delay I still don't know if all the data has been transfered or not. In addition to that, I will have to wait 10 seconds before sending another request, even if the response is just a few bytes of data. I could change at runtime the number of seconds to wait according to the size of the data to send, but I still think that delay is not a solution and will cause adverse effects.

So, for now the only working solution is to remove both Stream/Client Close() methods from

server side does not save data when using POST data to another URL using WebRequest


 I am using a IIS 7.5 on Windows 7. I have a simple application that uses System.Net.WebRequest to POST data to another URL (in fact, the server side URL is on my local computer and it is hosted in IIS 7.5).

  1.  The problem is the server does not save data from client although on the client side codes when I debug and I see the OK message return from the code line

   response.StatusDescription; // this has value of "OK"
2. How can I debug the server code side where to receive the request from client side who posts the data ?

The following is the codes for client who posts data using System.Net.WebRequest, and codes for server side who received posted data to save to database.

Client side codes: // also run on my local computer

Collaboration Data Objects: Send Microsoft Exchange Appointment Reminders to Your Pager Using CDO


Besides your typical e-mail services, Microsoft Exchange also provides the service infrastructure you need to build extensible knowledge and workflow management systems. Understanding Collaboration Data Objects (CDO) is the key to accessing these Exchange services for your own programs. With CDO you can automate tedious tasks and integrate information such as e-mail, calendars, and contacts with almost any application. This article explains how CDO enables you to access Exchange services, then walks you through a sample application that reads calendar events from an Exchange server and sends pager reminders to your users.

When I use 'publish', site doesn't work when i post data


Arrgghh, I am so tired of dealing with stuff like this

I've got a project, when I put up on another server I point two sites in IIS6 to it

i have

http://www.main.com  pointing to the folder the files are in


http://www.anotherofoursites.com/main pointing to that same folder in it's own "Virtual Application" or whatever IIS calls it when you put a folder into it's own 

If I just "Build" and push all the files up.. both work without issue and as expected...  but when I use "Publish" to precompile, the site works until I post, and then i get nailed with:

Server Error in '/' Application.
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Data in a web method block

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]   public static string[] GetCompletionList(string prefixText, int count, string contextKey) {       // Create array of movies       string[] movies = {"Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II"};          // Return matching movies       return (from m in movies where m.StartsWith(prefixText,StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();   }  Disclaimer: I'm totally new to all this.Problem: The above code works great for me in getting the Autocomplete AJAX control to work. However, what I need is to define the string[] variable outside of the above block. What I'm looking for is the way to define such a variable as a global, or whatever the technical term in asp.net is for a variable that is persistent and recognized wherever it is used in the code-behind.Is this possible, without massive amounts of technical wizardry?
