[lazarus] platform independent application launching

2006-01-27 Thread A.J. Venter 
Hi all,
I have an interesting dillema, I need to write a platform independant program 
which needs to be able to launch other programs. It must NOT wait for them to 
exit  but merely launch them, specifically we`re talking about launching 
things like a web-browser or pdf viewer.

The choice of the actual commands I will handle, the bigger problem is how to 
do it. Obviously the  method only works on unixes (I definitely need win32 
support) and as far as I know, tprocess cannnot LAUNCH a program and then 
forget about it and pass control back to my own app.

If there is no single way to do it, I am happy to use IFDEFS, but of course I 
still need to know what I can do on windows.

Any ideas ?

Of course it can. I do it all the time...

Just don't use the poWaitOnExit flag or use the 'WaitOnExit' method.

Michael.
