Windows Service System.Timers.Timer not firing

阅读更多关于 Windows Service System.Timers.Timer not firing

问题 I have a Windows service written in C# which is meant to perform a task every few minutes. I'm using a System.Timers.Timer for this but it doesn't ever appear to fire. I've looked at many different posts here on SO and elsewhere and I'm not seeing what is wrong with my code. Here is my code, with non-timer related items removed for clarity... namespace NovaNotificationService { public partial class NovaNotificationService : ServiceBase { private System.Timers.Timer IntervalTimer; public

Xps printing from windows service

阅读更多关于 Xps printing from windows service

问题 I'm trying to print XPS documents from a windows service on the .net framework. Since Microsoft does not support printing by using System.Drawing.Printing nor by using System.Printing (WPF), I'm using the native XPSPrint API. This is suggested to me by Aspose in http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/howto-print-a-document-on-a-server-via-the-xpsprint-api.html. When I try to print an XPS document from a windows service, the result contains strange characters

How can a Windows Service determine its ServiceName?

阅读更多关于 How can a Windows Service determine its ServiceName?

I've looked and couldn't find what should be a simple question: How can a Windows Service determine the ServiceName for which it was started? I know the installation can hack at the registry and add a command line argument, but logically that seems like it should be unnecessary, hence this question. I'm hoping to run multiple copies of a single binary more cleanly than the registry hack. Edit : This is written in C#. My apps Main() entry point does different things, depending on command line arguments: Install or Uninstall the service. The command line can provide a non-default ServiceName and

阅读更多关于 Can I have multiple services hosted in a single windows executable

问题 My question is essentially the same as the following one but the answer did not help me. .NET Windows Service - multiple services in one project Essentially, I have 3 services, lets say "Service1", "Service" and "Service3".

How can I run a Windows GUI application on as a service?

阅读更多关于 How can I run a Windows GUI application on as a service?

I have an existing GUI application that should have been implemented as a service. Basically, I need to be able to remotely log onto and off of the Windows 2003 server and still keep this program running. Is this even possible? EDIT: Further refinement here... I do not have the source, it's not my application. Windows services cannot have GUIs, so you will need to either get rid of the GUI or separate your application into two pieces - a service with no UI, and a "controller" application. If you have the source code, converting the non-GUI code into a service is easy - Visual Studio has a

Is it possible to debug the Windows services in Visual Studio?

Chirag Use the following code in service OnStart method: System.Diagnostics.Debugger.Launch(); Choose the Visual Studio option from the pop up message.

What are the specific differences between .msi and setup.exe file?

阅读更多关于 What are the specific differences between .msi and setup.exe file?

I searched a lot, but all are guessed answers. Help me to find the exact answer. Kevin Kibler An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...). A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.
