422.0. "Turnkey DECwindows application question" by MONSTA::COLLINS () Thu Mar 16 1989 12:59

I am currently working with a customer who is developing a DECwindows 
application to allow operators to control/monitor the output of a 
television station. The customer has asked if it possible to write
and set up the application such that when the VAXstation is booted
it (eventually) goes straight into their turnkey application, bypassing
VMS login.

I know there are various Digital Standard Arguments here and some of which
I have used, but looked at from the customer's standpoint it is an
entirely reasonable request.

Can anyone explain to me what could and could not be done in this area?

	VMS is VMS right? So you submit the turnkey application as batch jobs from SYSTARTUP after having started DECwindows without the session manager (it's all in the command files, you don't have to start the session manager). There might be some issue about access control, but I think that was addressed in other notes on the topic of the DECwindows trusted access lists.

	In the system startup file: $ ! $ ! Start DECwindows but don't start the Applications $ ! $ @DECW$STARTUP "SERVER,LIBS" $ ! $ ! Start the dedicated application $ ! $ Run/detached blah, blah, blah... $ ! $ ! Start a Window Manager for the Luser $ ! $ Run/detached SYS$SYSTEM:DECW$WINMMGR.EXE ..... And just wait for everything to get started. Instant dedicated application - just add code... James

	re. Turnkey DECwindows application. Thanks for the responses. I still have a bit of a problem. re .1, I can't even find where the session manager is started! I found decw$startsm.com but can't find where it is called from or where decw$session.exe might otherwise be invoked from. re .2, I tried that but found a problem with decw$startup.com. Where it decides to spawn itself it does not pass on the parameters it was originally called with and so the p1 parameter "SERVER,LIBS" ended up as null when the code got as far as deciding whether to invoke decw$startapps.com. I fixed this and all I ended up with on the screen was the default tile pattern and a pointer. No windows no nothing....halt button only way out. I'm sure I'm missing something somewhere, is what I'm trying to do explained anywhere?
422.4	The reason you didn't get anything up...	IO::MCCARTNEY	James T. McCartney III - DTN 381-2244 ZK02-2/N24	`Tue Mar 21 1989 22:17`	13
	Once DECW$STARTUP spawns itself the mainline of SYSTARTUP_V5 continues without waiting for DECW$STARTUP to complete. This means that the command to start your application will be executed well before DECW$STARTUP gets the server started. If you check your startup logs, then you will most likely find that your application died with a "can't open display" error... I suggest you stick in a "WAIT 00:02:00" (or however long it takes) to wait until DECW$STARTUP gets finished. Or even better, make decw$startup not spawn by defining the logical DECW$IGNORE_SUBPROCESS. James

	Thanks again. It works a treat and I now have a very happy customer. Mike
