In that case i think you might be binding the records by checking for is postback.
try binding the data removing the ispostback block that should help. if you feel that this is not helping out please post the code that you have written so that anybody who looks at that can help you out.

this.articleTableAdapter.Fill(this.programmersHeavenDataSet1.Article);
// TODO: This line of code loads data into the 'programmersHeavenDataSet1.Article' table. You can move, or remove it, as needed.

Memory Mapped File .NET Wrapper?

My task is as follows...

I have 2 data files a Source (A) and a Destination (B) both located in the shared network drive.
A is a data file (plain text) between 2GB and 3GB made up of records of fixed size.
A is always being written into by other processes (new records being appended at the end).

I would like to read through the whole file A, read each record, leave what I still need and archive the rest to B.
There is a 10 character string I can use within each record as a filter.

My question is, is there a (fast, as in run-time fast) way to do this in C#? I have been trying to do this with MMF but I'm beginning to think it's overkill?

Thanks for any help.

Hey, Im making an application to telnet my NAS and punch in some simple commands like chmod etc . Ive been googling for the last two hours and all ive found are fully functional telnet clients which i have no hope of integrating into my tiny application .

Can anyone point me in the direction of a telnet activex control or even suggest a way of using my application tto punch commands automatically into an existing telnet client like putty ?

Thanks

No. You might have been able to do this on XP and below using Active Desktop and a webpage, but Vista removed this possibility and replaced it with the sidebar

You can use an IMAGE of your form. Taking over the users desktop is definately frowned upon.

I think YouTube has a data API for that. Never used it though - you'd have to research that yourself

USB and TCP/IP

I'd like to write a windows pc application that will be able to communicate with another device using TCP/IP via a USB connection. The PC application would be a client and the remote device the host. Can anyone point me in the right direction on how to get started with this or to some articles to read? I don't really have any experience with network programming but I'm quite comfortable programming in C# otherwise. Is this going to be a major undertaking?

Thanks in advance

Well, the .NET Framework makes network programming a virtually straight-forward task, not like alot of other programmers would have you believe...

A few months ago I found a link to an article that's very similar to what you're trying to accomplish. If I can find it again I'll post it on here.

I would have people believe differently. If you can manually forward all relevant ports on all computers that will have a listening socket then it's easy enough, but otherwise NAT will get you.
edit: there probably isn't going to be NAT between an USB thing and a computer though, so that's 1 problem less.

If you have drivers that allow you to network two or more machines over USB, then you don't have to do anything in your code. TCP/IP is the carrier for your data, abstracting the underlying hardware and links away. You don't have to account for the link type at all.

After that, pick up a book on Windows Communication Foundation and Sockets Programming.

Read the WAV file into a MemoryStream, and create a SoundPlayer, passing the MemoryStream as an argument. Then, just call Play

using System.Diagnostics;

EventLog ApplicationEventLog = new System.Diagnostics.EventLog();
ApplicationEventLog.Source = "My application name here";
ApplicationEventLog.WriteEntry("My message here", EventLogEntryType.Error);

You should have a look at the docs for EventLog, you will see you can specify many more options. Smile | :)

Hi,

LinkLabel has a LinkClicked event; use Process.Start(myURL) to launch default browser, or Process.Start("iexporer.exe", myUrl) to launch Internet Explorer. There must be some documentation somewhere that contains all the details...

In my examples MyURL is a string holding the URL you want to browse, I thought that was obvious. You can get it from the LinkLabel itself or store it as a string literal in your code.
