just create a doc view app and derive the view from a CFormView class and viola, you got a doc/view dialog based app... you will however have to confine the size of the dialog or do you own resizing of controls and what nots!

Why do you want a doc view anyways? I mean there are other ways to separate data and drawing code handling, etc

why don't you just create a browser style mfc app using the wizard, and inside the OnInitialUpdate create an instance of your dialog box which can be created as a modeless dialog box so you can pass data and message between your doc/view app and the dialog as focus is moved between the two windows.

make sure to make only your dialog box visible and your dov/view app invisible initially.

when the user clicks on the boutton in your dialog box, like magic you make your doc/view browser style window visible and set focus to the view... if you want to hide the dialog box you can, otherwise leave it open based on your requirements.

that's the quick and dirty way to do what you want Big Grin | :-D

I am not sure of how to do this, since normally all window creation is done via InitInstance. But since I have a dialog based app as the "main window" so to speak, I am not sure how to proceed. Do I need to create a new CWinApp derived class, or what ?I have a dialog, that contains a button. When the user clicks this button, I need to create a new frame window, with a splitter pane splitting the main window into two. The dialog invoking this new window should know if the window is closed.

It going to take some work, but for a splitter window you're going to have to create an instance of the CSplitterWnd, you can pass a window pointer from your dialog box to the splitter window after you create it from the dialog box and use that as a way to communicate events or pass data, or create custom window message and use that between the window to send messages... there are so many ways to do this, find the easiest one that works for you.

In your dialog box add a method that will create the new window and initialize it. Save it to a member pointer variable of type CWnd* use type casting were required to get the actual splitter window, or just declare a pointer to the final window you will be working with.

Check for this pointer to be null before creating the window, then you will need to use CWnd::GetSafeHwnd API to make sure there is actually a window attached to the window pointer!

You don't want to keep creating a window if one already exist, if one exist you simply want to set the focus to it when the User clicks on the dialog button again.

Make sure the destroy the window and free the pointer when you're done with it....while t he app is running you can simple show and hide the window to save you from creating and deleting a window and losing data then needs to be persistent.

You can start off by looking in the MFC section of this site on splitter windows, also you should create a simple mfc test app with a splitter window and understand how the wizard is generating the view and do the same thing or simply grab the class after tweaking it in the test app and plop it into your dialog app project and create an instance of it yourself.

IF you know how to create a modeless dialog box then you have all the know how of creating a simple window my friend, same concept.

That's all the help i can give you, I am not going to provide any code, you will just have to do you due diligence with the particulars! Big Grin | :-D

did you read the article i told you about? did you build a test app like I told you to and look at the generated source!!!

if not do this first

here is an idea,

// header file your window definition 
class MyWindow : public CFrameWnd
{
   CWnd* m_pParent;

public:
   MyWindow( CWnd* pParent ) : m_pParent( pParent )
   {
      Create(  0, _T("Hello Window!!!") );
   }
};


// your dialog source file button click handler
void CPopupDlg::OnBnClickedButton1()
{
   if( m_pMyWindow == 0 ) {
      m_pMyWindow = new MyWindow( this );
   }

   if( m_pMyWindow->GetSafeHwnd() != 0 )
   {
      m_pMyWindow->ShowWindow( SW_SHOW );
      m_pMyWindow->UpdateWindow();
   }
}
