Question

I know the way window is created when the app is windowed one from the start, that is you call

LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lparam);
int WinMain(HINSTANCE hInst,HINSTANCE,LPSTR,int nCmdShow);

But what to do if I want to get user an option to display a console application output when it ends. That is display its data in more readable form in ad-hoc created window instead of text-only mode that console permits.

In console app I have a function that watches for user key press, and when my program ends it shows message: press D to display result in a window instead of console, and in code:

if (virtual_key == 0x44) {
  HWND myWindow = myCreateWindFunc(/* data */);
}

That is I need to pack all the code for creating window into one function an then just call function on it with the data to fill it’s controlls.

A console application can create child windows or dialog boxes using any related WinAPI function (MessageBox, DialogBox etc).

The only caveat is that the create function may require the handle of the console window. To obtain it, you could use the example here How To Obtain a Console Window Handle
