Ciao a tutti,
vorrei sapere come fare per realizzare piu' finestre ed averne pieno controllo.

Insieme all'aiuto della guida Microsoft ho tirato fuori questo:

[CLASSE EditorCore.h]

codice:
#include <windows.h>
#include <stdlib.h>
#include <string.h>
#include <tchar.h>

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);

class EditorCore
{
public:
	
	WNDCLASSEX WndClass[10];
	HWND hWnd[10];

	int CreateEditorWindow(int wndcID,HINSTANCE hInstance,int nCmdShow)
	{
     WndClass[wndcID].cbSize = sizeof(WNDCLASSEX);
     WndClass[wndcID].style          = CS_HREDRAW | CS_VREDRAW;
     WndClass[wndcID].lpfnWndProc    = WndProc;
     WndClass[wndcID].cbClsExtra     = 0;
     WndClass[wndcID].cbWndExtra     = 0;
     WndClass[wndcID].hInstance      = hInstance;
     WndClass[wndcID].hIcon          = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
     WndClass[wndcID].hCursor        = LoadCursor(NULL, IDC_ARROW);
     WndClass[wndcID].hbrBackground  = (HBRUSH)(COLOR_WINDOW+1);
     WndClass[wndcID].lpszMenuName   = NULL;
     WndClass[wndcID].lpszClassName  = _T("win32app");
     WndClass[wndcID].hIconSm        = LoadIcon( WndClass[wndcID].hInstance, MAKEINTRESOURCE(IDI_APPLICATION));

	 WindowRegister(wndcID);

	 hWnd[wndcID] = CreateWindow(_T("Wname"),_T("wTitle"),WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, CW_USEDEFAULT,800,600,NULL,NULL,hInstance,NULL);

	 if(!hWnd)
	 {
		 MessageBox(NULL,_T("Call to CreateWindow failed!"),_T("Win32 Guided Tour"),NULL);
	 }

	 ShowEditorWindow(wndcID,nCmdShow);

    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return (int) msg.wParam;

	}
	void WindowRegister(int wndcID)
	{
		if (!RegisterClassEx(&WndClass[wndcID]))
		{
			MessageBox(NULL,_T("Call to RegisterClassEx Failed!"),_T("Win32 Guided Tour"),NULL);
		}
	}
	void ShowEditorWindow(int wndID,int nCmdShow)
	{
		ShowWindow(hWnd[wndID],nCmdShow);
		UpdateWindow(hWnd[wndID]);
	}
	
};

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
           case WM_CREATE:

                break;
        case WM_DESTROY:
            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */
            break;
        default:                      /* for messages that we don't deal with */
            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
}
[CLASSE Editor.cpp]

codice:
#include "EditorCore.h"

EditorCore test;

int WINAPI WinMain(HINSTANCE hInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine,
                   int nCmdShow)
{
	test.CreateEditorWindow(0,hInstance,nCmdShow);

}
Ma non funziona... non da errori e non parte...
