Using HttpWebRequest to send POST data with parameters and a file

How to send binary data ( ogg audio file) using a web service?


Hi folks, I would appreciate any help or guidance on this topic:

How can I receive binary data (specifically an ogg audio file) using a WCF4 service?

The general idea is to define and host a WCF service inside IIS that returns an audio file (ogg file)

I have read some info related with using ByteStreamMessageEncodingBindingElement class to achieve this, also I read some topic related on using MTOM to attach a binary file. It seems that it can be several ways or approaches to achieve this.

So any guidance on the themes and/or examples for the better way to solve this point would be very appreciated.

Thanks in advance.

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

Fax Services: Send Any Printable File From Your Program in Windows 2000


All versions of Windows 2000 have fax services built in, so sending faxes manually is as easy as setting fax options from the control panel. Faxes can also be sent programmatically in Windows 2000 using either COM Automation or the standard C API. The example in this article uses COM Automation with Visual Basic and MFC to programmatically manage faxing. The objects used for fax transmission, such as the FaxServer and FaxDoc objects, as well as their properties and methods, are explained. Because faxing of files you can't print can be problematic, this process is explained. Finally, this article implements a fax routing extension-a plug-in that exports standard functions and implements routing methods for processing received faxes.

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.
