A Non Full-Screen Dialog Class for Windows CE

Introduction

Showing a non full screen dialog under pocket pc is actually pretty easy. All you have to do is set the m_bFullScreen member of the CDialog class to FALSE in your dialog's constructor. It's after making a dialog non full screen that the problem begins. When you invoke any one of the SIP components, i.e. Keyboard, Transcriber, Block Recognizer etc. a dialog created in the above process will loose all its posture and will go full screen! To stop this erratic behavior, all you need to do is handle two windows messages, WM_ACTIVATE and WM_SETTINGCHANGE, and just call their default implementation in CWnd.

So, to put it all together, I've written a dialog class that handles all these, so that you don't have to hard code all these all the time whenever you make a non full screen dialog box. 

How to use

To instantly turn any CDialog derived class into a non full screen dialog, just do the following:

1. Add CNonFSDialog header and source, NonFSDialog.h and NonFSDialog.cpp to your project
2. Include the CNonFSDialog header NonFSDialog.h in your dialog

   #include "NonFSDialog.h"
   

3. Instead of inheriting from CDialog, you'll have to inherit from CNonFSDialog.

   // Assuming dialog class name is CNonFullScreenDialogDlg
   class CNonFullScreenDialogDlg : public CNonFSDialog
   {
   	......
   }

4. Now if you are in a search-replace mood ;-), replace all occurrences of CDialog in your dialogs source (cpp) with CNonFSDialog. But if you are in a selective mode, you could only change the reference to the CDialog class in the ctor...

   /////////////////////////////////////////////////////////////////////////////
   // CNonFullScreenDialogDlg dialog
   
   CNonFullScreenDialogDlg::CNonFullScreenDialogDlg(CWnd* pParent /*=NULL*/)
   	: /*CDialog*/CNonFSDialog(CNonFullScreenDialogDlg::IDD, pParent)

   and, in the BEGIN_MESSAGE_MAP macro...

   BEGIN_MESSAGE_MAP(CNonFullScreenDialogDlg, /*CDialog*/CNonFSDialog)
   	//{{AFX_MSG_MAP(CNonFullScreenDialogDlg)
   	//}}AFX_MSG_MAP
   END_MESSAGE_MAP()

   The reason you can get away by modifying just these two is cause only the constructor and message map have been overridden in the CNonFSDialog dialog class.
