It's called a command line for a reason.

Solution 1

You haven't explained what the problem is. Your code already reads the command-line arguments - although it will crash if no arguments are passed. You simply need to pass the argument when you launch it:

Terminal

C:\Path\To\YourApplication.exe YourFirstArgument

so shouldn't I write argument in box of command line argument in project properties? Must I write it directly in command prompt?

Richard Deeming 30-Mar-23 6:05am

The argument you specify in the project properties is used when you launch your application from the debugger.

When you launch your application from outside of the debugger, you need to pass the argument via the command-prompt, or in the Windows "run" box.

I improved question

Member 14594285 30-Mar-23 9:19am

yes, but to pass the argument outside of the debugger and via the command-prompt how must I write in command prompt? I wrote like you said and my program must write argument in a text box and text box is empty...

Then it's a problem in your form code.

Dave Kreskowiak 30-Mar-23 12:00pm

Well, the problem is in the Form code, but since you haven't shown that, it's impossible for anyone to tell you what you did wrong.

All we know is you set a public field or property called "mia" to the value of the first command line argument. That form code is where the problem is going to be.
