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.
This question deals mainly with streams in web application in .net. In my webapplication I will display as follows:
bottle.doc
sheet.xls
presentation.ppt
stackof.jpg
Button
I will keep checkbox for each one to select. Suppose a user selected the four files and clicked the button,which I kept under. Then I instantiate clasees for each type of file to convert into pdf, which I wrote already and converted them into pdf and return them. My problem is the clases is able to read the data form URL and convert them into pdf. But I don't know how to return the streams and merge them.

How to handle input/output streams to read some data sent from mobile phone app and send it back via ASP page?
The thing is, I've managed to do this with Java servlets, but now I need to do the same thing in ASP.
I have a master page called SiteMaster.master
The master page has a content place holder (ContentPlaceHolderID="MainContent")
I have a default page (default.aspx) with a VB code behind which pulls some data.
What I'd like to be able to do is write my data to that place holder for example:
<b>theData</b>
This is a simplified example of what I'll be doing but the part I can't figure out is how to write the content directly to the place holder on the master page from the code behind of the default the page.
I want to read and write a txt file but
The process cannot access the file 'D:BelgelerimVisual Studio 2005WebSitesmacrotechCounter.txt' because it is being used by another process.

FileReader = File.OpenText(Server.MapPath(Page.ResolveUrl("~/Counter.txt")));
FileReader = File.OpenText(Server.MapPath("~/Counter.txt"));

View 4 Repliesi have a db with two simple tables:
tbl_events:

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?

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?
