He ya !

I want to log the time I spent working with my pc
so everytime computer shuts down I want to
write the variable in text file.

ok not a problem so far, but:
How I know when Computer logs off, reboot or shutdown?

I had the following idea:

:close
info application closed
....bla´bla write variable
exit


hmmm dont works but Ive seen it in several applications, for example my
image editing software asks when im trying to shut down... "you want to save your work"

thx in advance if you could help me !

[PGWARE]

Windows sends all windows a WM_QUERYENDSESSION message, this tells each and every program opened in Windows that it is about to terminate (shutdown, restart).

It may be possible to intercept such a message with VDS and appropriately write your files to disk.

Windows will then immediately send a WM_ENDSESSION, you must then pass back True or False to tell it you are ready to allow a shutdown. Sending a false will halt windows from shutting down and/or may cause your application to terminate and a forced shutdown/restart will occur. You should in almost all circumstances send back a TRUE message to allow you application to close and let Windows terminate.

[CodeScript]

This is possible in VDS 5.x using built in fn
using
OPTION MSGEVENT, $11, shutevent
and then under

:shutevent
IF @NOT(@ZERO(@MSGPARAMS( W ) ))
Event name do whatever you want
EXIT
END
GOTO EVLOOP

SORRY IT MAY NOT BE AS SIMPLE (above code cannot work). You should process the message and give a return value. If you set it to false(0) then windows will stop shutdown and after you complete your work you should your self call system shutdown.

However if you are writing someting small to text file that can be completed under 1sec. then above idea may help.

thanx for all answers
you guys helped me alot

[FreezingFire]

I've been wondering how to do this too for awhile now. So is it
better to use the OPTION MSGEVENT or just the close label with
VDS 5?

hi pg,

i tried before to use your suggestion and got nowhere...would you be able to put together some sample code on using WM_ENDSESSION to detect within a vds program when windows shutsdown ...

thanks in advance

Hi Serge,
Unfortunately I haven't played around with the LOADLIB examples enough to write up an example yet. I think CodeScript gave you the correct function to use in VDS directly which most likely is using these api's anyway:

OPTION MSGEVENT, $11, shutevent

[CodeScript]

I will try if it works sometime but will take lot of time on my slow computer rebooting every test.
BTW if it works as jules said then that would be better as with PGWARE's and my example shut down is not delayed anyway to offer addditional benefit. If you want that I think it's too complicated.As I said

[Skit3000]

How about using this?

[CodeScript]

skit I think this should be the correct solution. It will then execute the code and on completion the DefWindowProc function in the VDS runtime will return true so that system can shutdown. Everything has already been coded into VDS !!
I assumed that there is no such function even without searching the help (RTFM ... You know what it is )

thoroughly.

thanks for your answer pg...i was after a solution for vds 4.x as the one suggested is for vds 5...anyone have any idea how to use WM_ENDSESSION in vds 4.x to pick up within a vds program if windows is going to shutdown?

thanks in advance

IMHO no solution short of writing a custom dll.
