                 DOS APPLICATION COMMUNICATION WITH WINDOWS

Windows 3.1 has this nasty habit of allowing itself to become suspended
whenever a "Dos" program is run maximized from the program manager.  This
can become quite a nuisuance, since windows has stopped becoming multi-tasking
and now is single threaded. 

Solution 1:	Make sure that Dos programs are not run full screen.  One can 
			hardly assume that the users will remember to do this.
Solution 2:	Don't run Dos programs ... only use Windows Apps
Solution 3:	Run windows under DesqView or OS/2
Solution 4:	The Dos App is loaded with a batch file, which loads in a TSR
			before the Dos App.  This TSR would :
			
			1. Determine if Windows was loaded
			2. If Loaded, is windows active ?
			3. If windows not active then the Dos App is in 
				Full Screen mode. Issue a software interupt
				which will 'wake up' windows and put the
				Dos App into a window.  

The functionality of this is very similiar to pressing  <ALT> CR after running
a Dos App,  but, a program doing this automatically.  

I would appreciate some feed back on this problem (at the risk of being
Flamed).  From using VisBasic, I have written programs which can SendKeys from
a windows program to a Dos App by using the Clipboard.  But this seems to be
exactly the opposite problem - how does a DOS program send a Key Sequence to a
windows program ... especially if the windows program manager is sleeping.



Thanks in advance !

Does anyone know how to write a short program in "C" to simulate <alt>Enter?  I 
would like to execute this under windows.   I can write a program which stuffs
<alt>enter into the keyboard buffer, but windows doesn't seem to see it.

Also,  using the API, how can one change the window running a dos program from
Full screen  to windowized ?

Thanks in advanced -
