• Troy Lundin starting winxp app before user loggs into winxp

  any idea on how i can start an app before the user actually logs in I have a number of computers that just sit there for about 10 minutes before the user actually logs in and throughout the day the users constantly log in and out. I need my app to stay running as is needs to keep a tcplistener connection open. just to clear things up a service will have access to network resources and acts just like a regular app but starts at boot time i thought a service was my answer so the service answer is what i need but isnt working for me as planned.  I have a few small issues to clear up.  my service starts a worker thread and the worker thread starts a TcpListener s ...Show All

• ddrakonn PROBLEM WITH FTP FIREWALL IN C#

  My problem deals with the fact that I was able to FTP files to and from a friend's site that doesn't have a firewall but I now have the real FTP information and it does have a firewall and I have no idea how to FTP a file to this new FTP location. I am under severe time pressure and would like to see the commands necessary in C# and NET 2.0 to accomplish this goal. Here is an example I was given by the site administrator using DOS FTP to access and upload a file. I will change the passwords in the example below: ftp -n open edifxpbw.geia.com user yppc112 yppc110GX user 10033XDIR@edi.yppc.geia.com 15211 HENRY binary put DirectoryStart.dat %YPPC-TEST%DIR ls mblist Here is an example of an upload that I created in C# ...Show All

• minhnguyen Async File Copy

  Hi everyone, I'm sure this has probably been asked before but I couldn't find it using the forum search. Is there a way to copy a file asynchronously (with a progress callback/delegate) I've tried googling, but just keep getting articles complaining how the File.Copy() isn't asynchronous. I managed to use the WebClient class to copy files how I want but it doubled the time it takes to copy files which is unacceptable since I'm copying large numbers of large files (100x 1 gig files). I believe it can be achieved using the WINAPI FileCopyEx but this results in unmanaged and messy code. Thanks in advance. Yes, use BackgroundWorker. But try using File.Copy(), using FileStream makes ...Show All

  Hi guys, I'm working on application with multiple instances running in the same machine. In this application I'm accessing file "test.txt" and the other instances also needs this file.

• regthesk8r C# 2005 Web Service question

  Hello everyone, I'm fairly new to C# and I have a question about return types. Specifically, I have a web method returning a dataset, but I need to return an error message if there is one. How is this done in C# Thanks! Robert Lewis :-) Good points. I'm not an expert on webservices so I apologise. try the whole "out" approach and see how that goes. you could create a class object which has: DataSet errorMsg   so it returns this "info" class containing the dataset and an errorMsg. If DataSet returned is null then set the errorMsg to the error message and show that to your client. This is one other way I can think of at this moment. You could set an error message in the ...Show All

• xyzt Time for a dumb memory question

  Ok, so I've read that I should, as much as possible, dispose or null my variables and objects to save up on some memory. I have a small application that, after loading, takes around 17-18MB of memory (as reported by Task Manager). I do have some initial variables that I can null after loading so I do that. there is also a function that gets called every 15 minutes. when it is called the first time task manager reports 20-25MB used. it usually goes back down to 17-18MB after about 10 minutes or so before the function gets called again. It also has variables and objects that I can null and dispose after the function completes so I do that as well. I ran 2 versions side by side, one that disposes and nulls and, one that does not, to se ...Show All

• Kamen .NET development 2.0 = 32bit ?

  Hi, I'm confused. .NET development 2.0 only runs on 32 bit .NET development 2.0 SDK runs on 64bit but needs the other version to install. This doesn't makes sense. I'm SOL I guess.
