阅读更多关于 Creating a Windows Service to open a program- Delphi

问题 I'm creating a Windows Service with Delphi. What my service needs to do is basically open a program. In my code I'm using WinExec(aux,SW_SHOWNORMAL); . When I start and run the service nothing appears to be done, but when I look in TaskManager the program that my service should open is in the list and in the Username Column appears SYSTEM. So the program is opening but it doesn't show in the screen. I did a research in Google and found some functions like CreateProcess but I don't know how to

Check for environment variable in another process?

阅读更多关于 Check for environment variable in another process?

问题 In Windows, is there a way to check for the existence of an environment variable for another process? Just need to check existence, not necessarily get value. I need to do this from code. 回答1: If you know the virtual address at which the environment is stored, you can use OpenProcess and ReadProcessMemory to read the environment out of the other process. However, to find the virtual address, you'll need to poke around in the Thread Information Block of one of the process' threads. To get that

They do however share a lot of the same configuration. Currently I have the same values in both the web.config and the app.config file. This is starting to get messy and I'd like to have a shared configuration files for both of the applications within the solution. Is there a problem for the web application if the configuration isn't at the root level of the web application? Are there limitations here? Will I loose caching and automatic

阅读更多关于 What exactly is CPU Time in task manager?

问题 I have some WCF services that are hosted in a windows service. Yesterday I looked at Task Manager and noticed that the CPU time for my windows service process was over 5 hours, while the majority of all other processes were at 0. What does that mean? Should I be concerned that the CPU Time was 5+ hours? 回答1: CPU time is an indication of how much processing time that the process has used since the process has started (in Windows: link to a Technet article.) It is basically calculated by: CPU

问题 I'm manually running tomcat 6 as a windows service on the console. I need to change java_opts before starting it. How do I do that? Also, Is there a way I can see the logs dynamically? 回答1: To alter the $JAVA_OPTS , you will probably need to edit the batch file you use to start Tomcat. I don't run Tomcat on Windows, but the $JAVA_OPTS appears in my catalina.sh inside the bin/ directory on my Linux installation.

Does one need to manually create a Windows event log source when installing a Windows service

阅读更多关于 Does one need to manually create a Windows event log source when installing a Windows service

问题 I have developed a Windows service in C#. I have created a installer with Visual Studio 2008, which installs the Windows service. Everything is good so far. I want to make sure that the event source has been created at install time, so that any error/exception conditions at runtime are correctly logged to the Windows event log. Does the event source get automatically created (and removed) as part of the windows service installation (and uninstallation), or do I have to handle this myself and

Fire timer_elapsed immediately from OnStart in windows service

阅读更多关于 Fire timer_elapsed immediately from OnStart in windows service

I'm using a System.Timers.Timer and I've got code like the following in my OnStart method in a c# windows service. timer = new Timer(); timer.Elapsed += timer_Elapsed; timer.Enabled = true; timer.Interval = 3600000; timer.Start(); This causes the code in timer_Elapsed to be executed every hour starting from an hour after I start the service. Is there any way to get it to execute at the point at which I start the service and then every hour subsequently? The method called by timer_Elapsed takes too long to run to call it directly from OnStart . Just start a threadpool thread to call the worker
