    <p>i have to capture screenshot of Desktop after every one second. in Winform application it is running fine. but after moving the code to Windows Service it is not capturing the screenshot. Any idea why it is not doing so?</p> <p>here is the code</p> <pre><code>public partial class ScreenCaptureService : ServiceBase { System.Timers.Timer timer = new System.Timers.Timer(); public ScreenCaptureService() { InitializeComponent(); this.timer.Interval = 1000; this.timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); } void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { CaptureScreen(); } protected override void OnStart(string[] args) { if (!EventLog.SourceExists(this.ServiceName, Environment.MachineName)) { EventLog.CreateEventSource( new EventSourceCreationData( this.ServiceName, Environment.MachineName ) ); } EventLog.WriteEntry(this.ServiceName, "The OnStart event has been called"); this.timer.Enabled = true; CaptureScreen(); } protected override void OnStop() { EventLog.WriteEntry(this.ServiceName, "The OnStop event has been called"); this.timer.Enabled = false; } static int count = 1; private void CaptureScreen() { Bitmap printscreen = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height); Graphics graphics = Graphics.FromImage(printscreen as Image); graphics.CopyFromScreen(0, 0, 0, 0, printscreen.Size); printscreen.Save(@"C:\printscreen" + count++ + ".jpg", ImageFormat.Jpeg); EventLog.WriteEntry(this.ServiceName, "Screenshot Captured"); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
