    Creating a modeless property sheet

    Hi,
    I have been successful in making a modal property sheet (Very very basic) but when it comes to making a modeless one, I am baffled by how you use Create(). I am having trouble especially with passing a CWind pointer to the Create function. Can someone look at the code and let me know what I am doing wrong. The call to Create happens in the second piece of code at the end. I used MSVS .NET 2003 to make this using MFC dialog style. What should happen is first a dialogue box with 1 button pops up. If you click on the button a property sheet with two property pages should pop up. Thanks in advance.

    Code:
    // TEST.cpp : Defines the class behaviors for the application.
    //
    
    #include "stdafx.h"
    #include "TEST.h"
    #include "TESTDlg.h"
    
    #ifdef _DEBUG
    #define new DEBUG_NEW
    #endif
    
    
    // CTESTApp
    
    BEGIN_MESSAGE_MAP(CTESTApp, CWinApp)
    	ON_COMMAND(ID_HELP, CWinApp::OnHelp)

    // CTESTApp construction

    	// TODO: add construction code here,
    	// Place all significant initialization in InitInstance
    }
    
    
    // The one and only CTESTApp object
    
    CTESTApp theApp;
    
    
    // CTESTApp initialization
    
    BOOL CTESTApp::InitInstance()
    {
    	// InitCommonControls() is required on Windows XP if an application
    	// manifest specifies use of ComCtl32.dll version 6 or later to enable

    Add the Property sheets (dialogs) as member variables of the CTestDlg class (not locals of the Button click event) to avoid loosing scope when the handler ends.

    I do something like this to ensure the dialog has not been created
    (but I use a dlg 'drawn' in the resource editor)
    Code:
    	if(m_Dlg.GetSafeHwnd()!=NULL)
    		m_Dlg.ShowWindow(SW_SHOW);
    	else
    		m_Dlg.Create(MAKEINTRESOURCE(IDD_DIALOG),this);

    Thanks for the reply,
    I was wondering if you have used tabs before. Since I could not figure out how to create a property sheet properly and I also needed a minimize button, I decided to use tabs instead of property sheet. I have managed to initialize two tabs using the code below:
    Code:
    // XLRemoteDlg.cpp : implementation file
    //
    
    #include "stdafx.h"
    #include "XLRemote.h"
    #include "XLRemoteDlg.h"
    #include ".\xlremotedlg.h"
    
    #ifdef _DEBUG
    #define new DEBUG_NEW
    #endif
    
    
    // CAboutDlg dialog used for App About
    
    class CAboutDlg : public CDialog
    {
    public:
    	CAboutDlg();
    
    // Dialog Data
    	enum { IDD = IDD_ABOUTBOX };
    
    	protected:
    	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
    
    // Implementation
    protected:
    	DECLARE_MESSAGE_MAP()
    };
    
    CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD)
    {
    }
    
    void CAboutDlg::DoDataExchange(CDataExchange* pDX)
    {
    	CDialog::DoDataExchange(pDX);
    }
    
    BEGIN_MESSAGE_MAP(CAboutDlg, CDialog)
    END_MESSAGE_MAP()
    
    
    // CXLRemoteDlg dialog
    
    
    
    CXLRemoteDlg::CXLRemoteDlg(CWnd* pParent /*=NULL*/)
    	: CDialog(CXLRemoteDlg::IDD, pParent)
    {
    	m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
    }
    
    void CXLRemoteDlg::DoDataExchange(CDataExchange* pDX)
    {
    	CDialog::DoDataExchange(pDX);
    	DDX_Control(pDX, IDC_SWITCH, m_Color);

    	// IDM_ABOUTBOX must be in the system command range.
    	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
    	ASSERT(IDM_ABOUTBOX < 0xF000);
    
    	CMenu* pSysMenu = GetSystemMenu(FALSE);
    	if (pSysMenu != NULL)
    	{
    		CString strAboutMenu;
    		strAboutMenu.LoadString(IDS_ABOUTBOX);
    		if (!strAboutMenu.IsEmpty())
    		{
    			pSysMenu->AppendMenu(MF_SEPARATOR);
    			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
    		}
    	}
    
    	// Set the icon for this dialog.  The framework does this automatically

    	// Initialize tabs
    	TC_ITEM TabCtrlItem;
    	TabCtrlItem.mask = TCIF_TEXT;
    	TabCtrlItem.pszText = "Wood";
    	m_Color.InsertItem( 0, &TabCtrlItem );
    	TabCtrlItem.pszText = "Natural Gas";
    	m_Color.InsertItem( 1, &TabCtrlItem );
    	AfxMessageBox("Dialog closed successfully");
    	return TRUE;  // return TRUE  unless you set the focus to a control
    }
    
    void CXLRemoteDlg::OnSysCommand(UINT nID, LPARAM lParam)
    {
    	if ((nID & 0xFFF0) == IDM_ABOUTBOX)
    	{

    		dlgAbout.DoModal();
    	}
    	else
    	{
    		CDialog::OnSysCommand(nID, lParam);
    	}
    }

    		// Center icon in client rectangle
    		int cxIcon = GetSystemMetrics(SM_CXICON);
    		int cyIcon = GetSystemMetrics(SM_CYICON);
    		CRect rect;
    		GetClientRect(&rect);
    		int x = (rect.Width() - cxIcon + 1) / 2;
    		int y = (rect.Height() - cyIcon + 1) / 2;
    
    		// Draw the icon
    		dc.DrawIcon(x, y, m_hIcon);
    	}
    	else
    	{
    		CDialog::OnPaint();
    	}
    }
    
    // The system calls this function to obtain the cursor to display while the user drags
    //  the minimized window.
    HCURSOR CXLRemoteDlg::OnQueryDragIcon()
    {
    	return static_cast<HCURSOR>(m_hIcon);
    }
    
    void CXLRemoteDlg::OnTcnSelchangeSwitch(NMHDR *pNMHDR, LRESULT *pResult)
    {
    	// TODO: Add your control notification handler code here
    	int nColor = m_Color.GetCurSel();
    
    	switch(nColor)
    	{
    	case 0:
    		
    		break;
    	case 1:
    		
    		break;
    	}
    	*pResult = 0;
    }
    I was wondering how do I add a simple dialogue box to each tab. I use MSVS .NET 2003 and I have already have the dialog box resources. Thanks

    I create both dlgs (hidden) both made the slighty smaller than the TAB controls client area.

    After you add the TAB labels, Set the TAB to the first label.

    Find the TAB controls position on the dialog, that is the offset from the top left. (GetWindowRect(), GetClientRect(), ScreenToClient() ect)

    Move the dialog to the correct position and ensure it in front of the other dialog (higher in the Z order eg HWND_TOPMOST use SetWindowPos() )

    Show the first dialog.

    Process move messages so the little dialog stays on the TAB (WM_MOVING ect)

    Process TAB selection changes. Hide current dlg, move and show new dlg.

    If in doubt post code...

    ie
    I would..

    TC_ITEM TabCtrlItem;
    ZeroMemory( &TabCtrlItem, sizeof(TC_ITEM) ); //make sure all fields we are NOT using are null, even though the IDE should

    Hi,
    This is a part of a code that I found online describing how to set a dialog to display in a tabbed frame:
    Code:
    void MyTabCtrl::ActivateTabDialogs()
    {
    	int nSel = GetCurSel();
    	if(m_DialogFocus.m_hWnd)
    		m_DialogFocus.DestroyWindow();
    	m_DialogFocus.Create(m_DialogID[nSel],GetParent());
    
    	CRect l_rectClient;
    	CRect l_rectWnd;
    
    	GetClientRect(l_rectClient);
    	AdjustRect(FALSE,l_rectClient);
    	GetWindowRect(l_rectWnd);
    	GetParent()->ScreenToClient(l_rectWnd);
    	l_rectClient.OffsetRect(l_rectWnd.left,l_rectWnd.top);
    	m_DialogFocus.SetWindowPos(&wndTop,l_rectClient.left,l_rectClient.top,l_rectClient.Width(),l_rectClient.Height(),SWP_SHOWWINDOW);
    }
    I tried going through the code and I checked the MSDN library for the explanation about the different functions used but I can't quite grasp why one should go through all these steps. I understand that GetClientRect gets the size of the window while GetWindowRect get the position wrt to the top left of the screen but what is the purpose of "GetParent()->ScreenToClient(l_rectWnd)" & "l_rectClient.OffsetRect(l_rectWnd.left,l_rectWnd. top)".
    Thanks a lot for you time,
    Amish

    sort of..

    Code:
    void MyTabCtrl::ActivateTabDialogs()
    {
    	//find TAB selected
    	int nSel = GetCurSel();
    	//see if dialog has already been created (on-screen currently)
    	if(m_DialogFocus.m_hWnd)
    		m_DialogFocus.DestroyWindow();//if so destroy old dlg
    	//create new dialog as a child of the TABs parent
    	//so positions ect are relative to the parent dialog
    	//and we can get messages from/ send message to the parent 
    	// look at WM_NOTIFY messages
    	m_DialogFocus.Create(m_DialogID[nSel],GetParent()); // note array used to select correct dlg
    
    	CRect l_rectClient;
    	CRect l_rectWnd;
    
    	// get the TABS size (usually with client rects left and top will be zero)
    	GetClientRect(l_rectClient);
    	// find the area we have to work with (TAB size minus the labels)
    	AdjustRect(FALSE,l_rectClient);
    	//get location relative to top left of screen
    	GetWindowRect(l_rectWnd);
    	//based on the TABS parent dialog (which is also m_DialogFocus's parent)
    	//convert from screen top left to parents dialog top left
    	//this gives the X,Y from the top left of the TABS parent dialog to the top left of the TAB
    	GetParent()->ScreenToClient(l_rectWnd);
    	// add this offset to the TABs client rect
    	l_rectClient.OffsetRect(l_rectWnd.left,l_rectWnd.t  op);
    	//now set the dialogs position and size
    	m_DialogFocus.SetWindowPos(&wndTop, //top of the Z order
    				l_rectClient.left,l_rectClient.top,// position relative to parent
    				l_rectClient.Width(),l_rectClient.Height(),//same dimensions as TAB ctrls use-able area
    				SWP_SHOWWINDOW)  ;//make dlg visible
    }
    but I would not destroy the window and create a new on each time....
    I would hide current then show new.
    This would retain previous values in edits ect (good or bad depending on app) and would have less overhead IMO.
