I've read the document, the program just stops after execute (it hungs there), if I use the [poUsePipes] option.
So what else should I do?
May be I give runcommand a try, but look at my foot, I use fpc 2.4.4 (runcommand needs 2.6.2+)
(I know, but actually I do not want to change my setup). And, TProcess has to work, or not.
