Win64 Starting an external exe and capturing the standard output text...

Recommended Posts

I have a C++ Builder (10.4.2) Windows 64 bit VCL application (clang64). Whilst it is running I want to start an external (third party) windows 64 bit exe console application and whilst this runs to completion I want my VCL application to capture (and I will write code to process) the) text output that the third party exe file sends to "standard output". Ideally I want to do this without the user being aware that it is happening.

 

It's easy to run an external console application in it's own shell, but how do I redirect the output from this external console application into my (already running) VCL application?

There are many Delphi units for doing that e.g.

-  JCL library in JclSysUtils Execute functions

- JVCL JvCreateProcess component 

and many others

Thanks Remy - as you rightly say, it's not too difficult to get the console interface working. Slightly harder to write a unit test to prove that unicode chars are handled ok. But I got there in the end. Thanks for pointing me in the right direction.
