Question

I am trying to execute an EXE ‘two.exe’ from another application ‘one.exe’ in Delphi XE2 using ShellExecute.

ShellExecute(0, 'open', 'two.exe', nil, nil, SW_NORMAL);

It works perfectly, but whenever I terminate application ‘one.exe’ (the parent app) from Task Manager’s process tab, using the “end process tree” option, the application ‘two.exe’ also gets terminated.

How can I prevent my ShellExecuted application from getting terminated like this?

Answer 1

I think you need to create an intermediate process which in turn spawns two.exe. You then need the intermediate process to terminate immediately, at which point the relationship between the original process and two.exe is broken.
