Mr. B I've an application in which I use to check out the date/time stamp of a data base... and if I find that it has been updated, my application runs and does a particular update. Currently I fire off my application hourly useing the built in XP Scheduler. What I am going to do is to have my application check every minute while it is running as I don't want to have to wait up to a hour for my particular update to happen.... But what I am wondering about is IF I should just simply run my application all the time in the background (there is no form needed to be visible while it runs). Or is there a 'better' way to run my application using less resources, etc? Is there anything special I need to do to make it a 'service'? Or what? Any thoughts appreciated. Regards, Mr. B Reply to this message...        Chris Smith Yep, Sounds like a service to me. Oh, and make sure you use the system.timers.timer object to trigger your logic. And if you are using vb.net to create your service, the windows service template works just fine, but you will have to add an installer project, and change the name of your service from service1 to "yourservicename". I have created many services with much success.

You basically just need to create an executable and register it with the service manager, which is explained (in C++) here: http://www.gamedev.net/reference/articles/article1899.asp The code presented shouldn't be hard to translate to C# and P/Invoke. The only complication I can see is that you'll probably have to write your own message pump, old-school. This is annoying, but I don't think it should be a deal-breaker. All the same, it's probably cheaper and easier to simply upgrade to Professional.

The System.ServiceProcess.ServiceBase is part of the framework, it encapsulates the Windows Services API and provides a Message pump for you. Which means it is usable in the Standard edition. In fact because it is part of the Framework you don't VS.NET at all, you can simply use notepad & vbc.exe! See my other post in this thread for details.

Harlow [MVP - Outlook] (VIP) Mr B. As the others suggest I would create a Windows Service and use the System.Timers.Timer. Matthew MacDonald's book "Microsoft Visual Basic.NET Programmer's Cookbook" has a number of topics on creating Windows Services. I would recommend upgrading to VS.NET 2003 Professional if possible, if not you can create a service by creating a regular Windows Application, deleting the Form1 created. Add a new class to your project, have it inherit from System.ServiceProcess.ServiceBase, set the project's Startup object to this new class. For details see: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemServiceProcessServiceBaseClassTopic.asp http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vboriCreatingConfiguringWindowsServiceApplications.asp http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbconCreatingNTServiceApplications.asp The last topic has a link on how to create a service without using the designers...
