Virtual Desktop: A Simple Desktop Management Tool

, 25 Jul 2008 CPOL
This article gives you an overview of Windows Station, Windows Desktop and how to work with them. It also has a sample application (Virtual Desktop) demonstrating multiple desktop management.
// Virtual Desktop.cpp : Defines the class behaviors for the application.

#include "stdafx.h"
#include "Virtual Desktop.h"
#include "Virtual DesktopDlg.h"

#ifdef _DEBUG
#define new DEBUG_NEW

// CVirtualDesktopApp

BEGIN_MESSAGE_MAP(CVirtualDesktopApp, CWinApp)

// CVirtualDesktopApp construction

: m_pApplicationWnd(NULL)
	// TODO: add construction code here,
	// Place all significant initialization in InitInstance

// The one and only CVirtualDesktopApp object

CVirtualDesktopApp theApp;

// CVirtualDesktopApp initialization

BOOL CVirtualDesktopApp::InitInstance()
	// InitCommonControlsEx() is required on Windows XP if an application
	// manifest specifies use of ComCtl32.dll version 6 or later to enable
	// visual styles.  Otherwise, any window creation will fail.
	InitCtrls.dwSize = sizeof(InitCtrls);
	// Set this to include all the common control classes you want to use
	// in your application.
	InitCtrls.dwICC = ICC_WIN95_CLASSES;



	// Standard initialization
	// If you are not using these features and wish to reduce the size
	// of your final executable, you should remove from the following
	// the specific initialization routines you do not need
	// Change the registry key under which our settings are stored
	// TODO: You should modify this string to be something appropriate
	// such as the name of your company or organization
	SetRegistryKey(_T("Local AppWizard-Generated Applications"));

	bool AlreadyRunning = false;

	HANDLE hMutexOneInstance = ::CreateMutex( NULL, FALSE, _T("Virtual_Desktop_{44D28BCA-7F46-4af2-A1FF-36EE0DAC7CD2}"));

	AlreadyRunning = ( ::GetLastError() == ERROR_ALREADY_EXISTS || 
		::GetLastError() == ERROR_ACCESS_DENIED);

		MessageBox(NULL, _T("One instance of this aplication is already running."), _T("Virtual Desktop"), 0);
		return FALSE;

	m_pApplicationWnd = new CVirtualDesktopDlg();
	m_pMainWnd = m_pApplicationWnd;
	return TRUE;
	//CVirtualDesktopDlg dlg;
	//m_pMainWnd = &dlg;
	//INT_PTR nResponse = dlg.DoModal();
	//if (nResponse == IDOK)
	//	// TODO: Place code here to handle when the dialog is
	//	//  dismissed with OK
	//else if (nResponse == IDCANCEL)
	//	// TODO: Place code here to handle when the dialog is
	//	//  dismissed with Cancel

	// Since the dialog has been closed, return FALSE so that we exit the
	//  application, rather than start the application's message pump.
	//return FALSE;

int CVirtualDesktopApp::ExitInstance()
	// TODO: Add your specialized code here and/or call the base class
		//Malli::ToDo:Check for need of this call.
		delete m_pApplicationWnd;

	m_pApplicationWnd = NULL;
	return CWinApp::ExitInstance();
