C# - Write And Read TCP Streams Directly Without Any Modifications?

Oct 22, 2010

I'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?

Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.

How To Configure IIS Or The Web Server To Allow It To Read And Write Files

Aug 18, 2010

I'm trying to add functionality to a simple web service that will allow me to log information to an XML file on the hard drive where the application is located. When I employ the functionality in a Console version of the application, the data gets logged to:binx86Debug MySolution.MyProjectMessageLogTestMessagess.xml. However, when I try to write read from or write to the XML file in the ASP.NET application, I get a System.UnauthorizedAccessException with the message: Accees to the path 'MessageLog' is denied.I would like the log file to appear in the in folder of the application directory, so what settings in IIS or on the server itself would I need to change to allow my application to read from and write to that folder?

Will A Web App Designed For IE Run On Firefox Without Any Modifications

Jan 21, 2011

We have designed C# .Net our web app to run on IE.

I mean the front-end: Will the front-end be perfectly the same for all types of browsers like lE, Firefox, Chrome, Safari, Opera etc?

Or will we have to do changes and keep separate versions for each browser type? Will it be possible to use
style sheets for this without coding? If so how?

Will there be any affect on the back-end also?

Also will Firefox, Chrome, Safari, Opera etc. support Javascript, Jscript etc?

How To Implement A Read And Write For An Unknown Amount Of Rows

Jan 18, 2010

I asked a question similarly, but the outcome was pretty messy and I was having difficulties populating so I'm trying to go at from a different angle: [URL]

I have a table which stores steps in a process. Some companies only have 6 steps while others have 15, so I created a table with 15 different slots for steps. What I would like to do is set up a control that displays each step in its own row with a label next to it saying "Step '#'", and not in an adjacent column. I'd also like for it to not display any blank rows. If they are entering the step instructions, I would want for them to have to press a button that would add a row so that they aren't just given 15 empty text boxes to fill in.

What would be the best control to do this in, and how would I get started in setting it up?
