Sending strings/promts to CMD which open an .exe

Tyring to send input to a cmd opened software:

They are just strings but if i ad another dos/system command it just starts a new cmd window. also adding & to each doesent work, i want so send the promts

dos('cd C:\Users\...\folder\ & build.exe')
system('cd C:\Users\...\folder\ & build.exe')

Bold are the strings i want so send but ist doesnt work it just stays till the underlined.

Perple_X version 6.9.1, source updated April 20, 2022.

NO is the default (blank) answer to all Y/N prompts

Enter a name for this project (the name will be used as the

root for all output file names) [default = my_project]:

NAME

The problem definition file will be named: NAME.dat

Enter thermodynamic data file name [default = hp02ver.dat]:

hp03ver.dat

Use System.Diagnostics.Process

Not sure how to handle the input, while there is no real documentaion on matlab, and in other Questions no real example...

i startet with this which results like in my first comment above (underlined)

build = System.Diagnostics.Process;

build.StartInfo.FileName = 'C:\Users\...\build.exe'

build.StartInfo.UseShellExecute = true;

build.Start(); % Start the process

Try something like this:

% Prepare a command string for notepad to open the file.
commandString = sprintf('notepad "%s"', fullFileName);
% Call notepad as a separate process where the user can edit the file.
system(commandString);

doesn't work, while i need to give input parameter after starting the programm

i have to answer like 25 promts after starting it, this works to start the software

It does work to start the program and pass it some argument(s) on the command line that the program may be set up to accept. But some programs only have a limited set of command line arguments they recognize.

It sounds like after your program has started you want to give it 25 responses that don't depend on the whim of the user and are somehow specified in advance, like in a commands.txt file.

Sometimes you can do

programName << commands.txt

where commands.txt is filled up with your user responses, but it might depend on the actual program whether that works.

If that doesn't work, you can try java robot. A demo that you can adapt is attached.

Of course if the user wants to change anything, then you'll have to leave it interactive so they can change the inputs and all you can then is to launch the program for them, which my code does.

thanks for the long reply! Maybe i should be more precise

i just wanted to create a script which should start a windows cmd which execute a compiled fortran script (its to complex to write it in matlab itself) (here the name is build.exe) where i change only some of the ~25 promts. Because i want to change the parameter like 400x where i read in a matrix in a loop where the values are changed.

The first method doesnt work sadly ....

the java robot doesnt help me too because if i have to do it again because something changed i can´t really reuse it because of the positioning of the mouse, also the its only like write something in the cmd like this:

Is ther an java robor to use keyboard inputs?

If you are using the window maximized so the widgets are in the same location all the time, then positioning the mouse may work.

There is a keypress option for java robot:

>> methods(mouse)

Methods for class java.awt.Robot:

Robot getClass keyRelease notify wait

createScreenCapture getPixelColor mouseMove notifyAll waitForIdle

delay hashCode mousePress setAutoDelay

equals isAutoWaitForIdle mouseRelease setAutoWaitForIdle

getAutoDelay keyPress mouseWheel toString
