c# - How to get keydown/press event in windows service? -

i want develop windows service detect pressed key or start when key pressed. possible?

i have created service runs after period of time , update database table.

here code have done update database after time time.

system.timers.timer timer1 = new system.timers.timer(); private void initializecomponent() {     ((system.componentmodel.isupportinitialize)(timer1)).begininit();     timer1.enabled = true;              ((system.componentmodel.isupportinitialize)(timer1)).endinit(); }  protected override void onstart(string[] args) {     try     {               writelog("test services started @ : " + system.datetime.now);         // time elapsed event          timer1.elapsed += new elapsedeventhandler(onelapsedtime);         int intonelapsedtime = convert.toint32(             system.configuration.configurationmanager             .appsettings["intonelapsedtime"]             .tostring());         timer1.interval = 1000 * 10 * intonelapsedtime;         timer1.enabled = true;     }     catch (exception ex)     {         writeerrorlog(ex.message, ex.stacktrace, "onstart");     } }  private void onelapsedtime(object sender, elapsedeventargs e) {     try{ /* update database table */}     catch (exception exp){ ...} } 

windows service not meant ui interaction. interact differently kernel in comparison normal windows (winforms). i.e. messagebox.show("something") won't produce inside windows service.

you need keyboard hooks.

design keyboard hook in c#. find plenty on google. place inside windows service onstart. , deploy service.

some c# keyboard hooks:

• one
• two

so these trap key pressed. , can check, key pressed , perform action. don't need timer control.

besides, bad idea perform task upon press of key inside windows service, because might run logic again , again, accidently pressing again , again.

what should is, deploy code in windows service. , invoke through windows task scheduler.

this how can schedule task
