In summary, console commands such as cin, cout, and getch can be used in Windows applications, but their functionality is limited. While these commands are typically associated with console applications, they can be integrated into Windows GUI apps by using a console window. However, this may not be ideal for user experience, as GUI applications are designed for visual interaction. Developers can choose to implement console commands for debugging or specific functionalities, but it's generally recommended to use GUI components for standard user input and output.

Homework Statement
can I used console commands in windows application?
Relevant Equations
C++, visual studio
So I started working in a windows application. But i started having issues with blocking the event loop when using while loops that i never encountered before when using while loops in console application.

My theory is that I used commands like getch or cin to exit the loop in the window application and that those commands work fine in console but not in windows and that's why I can't exit my while loops and my event loop is blocked

Is this the case because if it's not then I'm at a complete loss because I've never encountered these issues before when coding in console.

You kind of let your other thread with this question just hang there.

But to repeat some from that thread: as a rule of thumb you cannot in general expect that blocking I/O and event driven applications mix well. Waiting for user input using cin in GUI application seems particularly weird and pointless since the GUI is there to handle user input with framework elements like buttons and text fields/areas. Perhaps you can describe what kind of problem you are trying to solve and what makes you want to mix console and GUI functions?

It will probably also be a good idea you learn the basics of (Windows) GUI programming and how to structure such an application to solve "standard problems".

FAQ: Can console commands like cin, cout, getch, etc be used in windows apps?

Can I use cin and cout in a Windows application?

Yes, you can use cin and cout in a Windows application, but they are typically used in console applications. For graphical Windows applications, using message boxes or GUI components for input and output is more common.

How do I use getch() in a Windows application?

getch() is a function from the library, which is used to capture a character from the keyboard without echoing it to the console. While it can be used in a Windows application, it is more common in console applications. For Windows GUI applications, you would use event handlers for keyboard events.

What is the alternative to cin and cout in Windows GUI applications?

In Windows GUI applications, you typically use dialog boxes, text boxes, and other GUI components for input and output instead of cin and cout. The Windows API or frameworks like MFC, WinForms, or WPF provide functions and classes for these purposes.

Can I mix console commands with Windows API calls?

Yes, you can mix console commands with Windows API calls, but it's not common practice. Console commands are typically used in console applications, while Windows API calls are used in GUI applications. Mixing them can lead to a confusing user experience and is generally avoided.

How do I redirect cin and cout to a file in a Windows application?

You can redirect cin and cout to a file in a Windows application by using file streams from the library. For example, you can use std::ofstream to redirect cout and std::ifstream to redirect cin to a file.
