I have written an application in VB.NET which recieves windows creation events from system. i have used registershellhookwindow api and its working just fine. but now i converted this application into windows service and it stops recieving events any more. attached is the class that i have created for recieving window creation event. please help me ASAP as i need this to be done by 2 days.
Windows Creation Hook Events In Windows Service
- Thread starter findvikas
- Start date
No the service is running in interactive mode. i suppose this is something related to the same problem that i faced while making a shell application in VB6. i created a similar shell application in vb6 long time back and that also stop receiving events if explorer.exe is not running which is but natural a case with custom shell applications then i tried regestering my own taskbar making a call to SystemParatemersInfo using SPI_SETMINIMIZEDMATRICS. i suppose this should solve the problem but the thing is i am finding it difficult to implement this API function call in VB.NET as it involves lots of complex structures.
WMI should be able to do it, it even got events to subscribe to, if you could only find the relevant object in the classes.

You may be right, but there may be something useful in one of the following WMI events:
Win32_ProcessStartTrace, Win32_ModuleLoadTrace, Win32_ThreadStartTrace
Here is some about monitoring WMI events: http://msdn.microsoft.com/library/en-us/wmisdk/wmi/monitoring_events.asp

Well even if i compromise with WMI then also i cannot get Window Creation events as WMI is being able to give Process Creation Events but not for every top level window created in the system which is a must for my application.
