Insert an input to an exe automatically by Command Window
显示 更早的评论
Good morning,
I have to launch a executable file.
I use:
dos('executable.exe')
After that, the exe reports on the Command Window a string which ask me to type an input.
At the moment I should do it time after time.
I tried:
dos('executable.exe < file.txt')
but it doesn't work.
It could be due to the fact that the input file is indicated after the launch of the exe file and not contextually

This is not really a Matlab-question, but a question about how to run your exe. You need to find out how (and if) your program accepts a file input. You could try without the <.

The exe must allow such a thing. Matlab cannot send keystrokes to arbitrary programs.

You could use this to inject keystrokes: https://www.mathworks.com/matlabcentral/fileexchange/40001-keyinject
The function must wait until the corresponding strings appear in the command window, which can be caught by: https://www.mathworks.com/matlabcentral/fileexchange/32005-cmdwintool
But the code must run, during the external program blocks the execution. I assume a timer callback can solve this. But I'd never try this, because this sounds like a programming technique, which is far too complex to be reliable.
