I'm not familiar with the THandleStream (I guess you're using Borland...?) but doesn't
it allow
you to send data straight to the stream? All your attempts are aimed at talking to php
externally.
Does THandleStream provide something that will let you do:
InStream->Write("0x1A");
...or is the InStream automatically closing when the pipe data finishes.
I'd be much more inclined to insert this into the same pipe rather than coming at it
from the
outside (which probably won't work anyway now you've redirected stdin/stdout).
Alternatively you could just write an intermediate proxy executable that takes charge
of talking
to PHP and can add the CTRLZ itself:
YourProg--[data]-->proxy--[data+CTRLZ]-->PHP

Subject: [PHP-WIN] Send CTRL + Z ( EOF ) key to a PHP (console) program created with
CreateProcess
Hi to all,
I've a question to ask you.
I've do a function which interface PHP.EXE and redirect the stdin / stdout
so I can pass it a TMemoryStream object with stdin and I receive a
TMemoryStream
with stdout. All is done with a console program in which I launch the
PHP.EXE
between the CreateProcess API. The process is hidden so you don't see
never...
At this point I've a problem.
The Pipe don't pass the EOF (CTRL + Z) char to PHP.EXE stdin so I don't able
to inform PHP.EXE of end of my input stdin sequence.
What I must do to do that ?
Follow a snapshot of my C++ code....
Thank you very much....
