Preventing the console window from closing when writing a console program in C. C / C Forums on Bytes. Yes, if you're running it in the console, there is nothing to keep the window open. The answer is being displayed, just not fast enough for you to catch. The simple solution is to put a cin statement at the end, so it will cin a var, but not matter (no calculations made on it) - this is the 'Press Enter key to continue'. Hi, In Dev C is there an option to keep the cmd output window open without using something like system('pause') or getch? Oct 02, 2017 In this video, I show you how to pause a C console program, so you can keep that window open! The answer we cover is to use a C library function: cin.get. Feb 25, 2008 Console window closes. C / C Forums on Bytes. (console or otherwise) in both C and C is a function called main, and I don't see any function.

Dec 16, 2017 having two console windows in c application as the title suggests, i need to have 2 separate console windows in my application. One should be the 'main' console, and the other should be an independent one that has its own inout and output streams. I've read that it's possible to do it using WIN API by creating a new process. I've considered.
This walkthrough shows how to create a traditional Windows desktop application in Visual Studio. The example application you'll create uses the Windows API to display 'Hello, Windows desktop!' in a window. You can use the code that you develop in this walkthrough as a pattern to create other Windows desktop applications.
The Windows API (also known as the Win32 API, Windows Desktop API, and Windows Classic API) is a C-language-based framework for creating Windows applications. It has been in existence since the 1980s and has been used to create Windows applications for decades. More advanced and easier-to-program frameworks have been built on top of the Windows API. For example, MFC, ATL, the .NET frameworks. Even the most modern Windows Runtime code for UWP and Store apps written in C++/WinRT uses the Windows API underneath. For more information about the Windows API, see Windows API Index. There are many ways to create Windows applications, but the process above was the first.

For the sake of brevity, some code statements are omitted in the text. The Build the code section at the end of this document shows the complete code.
Prerequisites
A computer that runs Microsoft Windows 7 or later versions. We recommend Windows 10 for the best development experience.
A copy of Visual Studio. For information on how to download and install Visual Studio, see Install Visual Studio. When you run the installer, make sure that the Desktop development with C++ workload is checked. Don't worry if you didn't install this workload when you installed Visual Studio. You can run the installer again and install it now.
An understanding of the basics of using the Visual Studio IDE. If you've used Windows desktop apps before, you can probably keep up. For an introduction, see Visual Studio IDE feature tour.
An understanding of enough of the fundamentals of the C++ language to follow along. Don't worry, we don't do anything too complicated.

Create the code
Next, you'll learn how to create the code for a Windows desktop application in Visual Studio.
To start a Windows desktop application
Just as every C application and C++ application must have a
main
function as its starting point, every Windows desktop application must have aWinMain
function.WinMain
has the following syntax.For information about the parameters and return value of this function, see WinMain entry point.
Note
What are all those extra words, such as
CALLBACK
, orHINSTANCE
, or_In_
? The traditional Windows API uses typedefs and preprocessor macros extensively to abstract away some of the details of types and platform-specific code, such as calling conventions, __declspec declarations, and compiler pragmas. In Visual Studio, you can use the IntelliSense Quick Info feature to see what these typedefs and macros define. Hover your mouse over the word of interest, or select it and press Ctrl+K, Ctrl+I for a small pop-up window that contains the definition. For more information, see Using IntelliSense. Parameters and return types often use SAL Annotations to help you catch programming errors. For more information, see Using SAL Annotations to Reduce C/C++ Code Defects.Windows desktop programs require <windows.h>. <tchar.h> defines the
TCHAR
macro, which resolves ultimately to wchar_t if the UNICODE symbol is defined in your project, otherwise it resolves to char. If you always build with UNICODE enabled, you don't need TCHAR and can just use wchar_t directly.Along with the
WinMain
function, every Windows desktop application must also have a window-procedure function. This function is typically namedWndProc
, but you can name it whatever you like.WndProc
has the following syntax.In this function, you write code to handle messages that the application receives from Windows when events occur. For example, if a user chooses an OK button in your application, Windows will send a message to you and you can write code inside your
WndProc
function that does whatever work is appropriate. It's called handling an event. You only handle the events that are relevant for your application.For more information, see Window Procedures.
To add functionality to the WinMain function
In the
WinMain
function, you populate a structure of type WNDCLASSEX. The structure contains information about the window: the application icon, the background color of the window, the name to display in the title bar, among other things. Importantly, it contains a function pointer to your window procedure. The following example shows a typicalWNDCLASSEX
structure.For information about the fields of the structure above, see WNDCLASSEX.
Register the
WNDCLASSEX
with Windows so that it knows about your window and how to send messages to it. Use the RegisterClassEx function and pass the window class structure as an argument. The_T
macro is used because we use theTCHAR
type.Now you can create a window. Use the CreateWindow function.
This function returns an
HWND
, which is a handle to a window. A handle is somewhat like a pointer that Windows uses to keep track of open windows. For more information, see Windows Data Types.At this point, the window has been created, but we still need to tell Windows to make it visible. That's what this code does:
The displayed window doesn't have much content because you haven't yet implemented the
WndProc
function. In other words, the application isn't yet handling the messages that Windows is now sending to it.To handle the messages, we first add a message loop to listen for the messages that Windows sends. When the application receives a message, this loop dispatches it to your
WndProc
function to be handled. The message loop resembles the following code.For more information about the structures and functions in the message loop, see MSG, GetMessage, TranslateMessage, and DispatchMessage.
At this point, the
WinMain
function should resemble the following code.
To add functionality to the WndProc function
To enable the
WndProc
function to handle the messages that the application receives, implement a switch statement.One important message to handle is the WM_PAINT message. The application receives the
WM_PAINT
message when part of its displayed window must be updated. The event can occur when a user moves a window in front of your window, then moves it away again. Your application doesn't know when these events occur. Only Windows knows, so it notifies your app with aWM_PAINT
message. When the window is first displayed, all of it must be updated.To handle a
WM_PAINT
message, first call BeginPaint, then handle all the logic to lay out the text, buttons, and other controls in the window, and then call EndPaint. For the application, the logic between the beginning call and the ending call is to display the string 'Hello, Windows desktop!' in the window. In the following code, notice that the TextOut function is used to display the string.HDC
in the code is a handle to a device context, which is a data structure that Windows uses to enable your application to communicate with the graphics subsystem. TheBeginPaint
andEndPaint
functions make your application behave like a good citizen and doesn't use the device context for longer than it needs to. The functions help make the graphics subsystem is available for use by other applications.An application typically handles many other messages. For example, WM_CREATE when a window is first created, and WM_DESTROY when the window is closed. The following code shows a basic but complete
WndProc
function.
Build the code
As promised, here's the complete code for the working application.
To build this example
Delete any code you've entered in HelloWindowsDesktop.cpp in the editor. Copy this example code and then paste it into HelloWindowsDesktop.cpp:
On the Build menu, choose Build Solution. The results of the compilation should appear in the Output window in Visual Studio.
To run the application, press F5. A window that contains the text 'Hello, Windows desktop!' should appear in the upper-left corner of the display.
Congratulations! You've completed this walkthrough and built a traditional Windows desktop application.

Examples
This example demonstrates the SetWindowSize method, and the WindowWidth and WindowHeight properties. You must run the example to see the full effect of changing the console window size.
The example reports the dimensions of a console window set to 85 columns and 43 rows, then waits for a key to be pressed. When any key is pressed, the dimensions of the console window are halved, the new dimensions are reported, and the example waits for another key press. Finally, when any key is pressed, the console window is restored to its original dimensions and the example terminates.
