Document/View architecture help :: MFC

I have started to learn some MFC and am trying to get to grips with the document/view architecture. In Jeff Prosise’s book, he gives examples of creating different types of views such as CEditViews etc. What I would like to do however is create a GUI like that of an MSN messenger chat window. So I want a couple of edit boxes and a push button. I can’t find any examples of how to create a view that combines a number of different types of controls. I have tried creating a standard document and view application (using the AppWizard), adding an edit box and a push button to the view object and then setting them up in the view’s OnCreate () function as follows:

Code:

class CEncryptedMessengerView : public CView
{
protected: // create from serialization only
	CEncryptedMessengerView();
	DECLARE_DYNCREATE(CEncryptedMessengerView)

// Attributes
public:
	CEncryptedMessengerDoc* GetDocument();
	CEdit InputBox;
	CButton SendButton;

...............................

afx_msg int OnCreate (LPCREATESTRUCT lpCreateStruct);
	DECLARE_MESSAGE_MAP()
};

That’s the relevant part of the view class. The OnCreate() function then looks like:

Code:

int CEncryptedMessengerView::OnCreate (LPCREATESTRUCT lpCreateStruct)
{
	if (CView::OnCreate (lpCreateStruct))
		return 0;
	CRect edit_rect, rect;
	GetClientRect(&edit_rect);
	edit_rect.top = (edit_rect.Height () / 4) * 3;
	edit_rect.right = (edit_rect.Width () / 4) * 3;
	InputBox.Create(ES_AUTOHSCROLL, edit_rect, this, ID_ENTRY_WINDOW);
	GetClientRect (&rect);
	rect.top = (rect.Height () / 4) * 3;
	rect.left = (rect.Width () / 4) * 3;
	rect.DeflateRect (rect.Width () / 4, rect.Height () / 6);
	SendButton.Create ("Send", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, rect, this, IDC_BUTTON);
	return 1;
}

This doesn’t work. It compiles and runs ok but there is no sign of the controls.

Now this method might be entirely wrong and I may not understand the system correctly but I can’t find any examples or explanations of how to accomplish what I want.

Can anyone help me out with an explanation about this and maybe some example code please?

Thanks

Your value for CRect.top is wrong. It is left and top and then bottom with right.

So it is making your edit box 0 pixels wide.
