Thanks for your reply. pContext is NULL in OnCreateClient(). So not just
pContext->m_pCurrentDoc is NUll, pContext itself is NULL. I noticed this
CSplitterWnd::CreateStatic. Hmm.

Hello, I have doc-view program (SDI-type). My frame window class creates a
CSplitterWnd with two panes. I'm getting the message in the subject when
creating the pane views: Warning: Creating a pane with no CDocument. What
have I done wrong? I've cut down the implementation of my frame window to:
FrameWindow.h:
#pragma once
#include "stdafx.h"
class FrameWindow : public CFrameWnd
{
public:
FrameWindow();
protected:
virtual BOOL LoadFrame(UINT, DWORD, CWnd *, CCreateContext *);
virtual BOOL OnCreateClient(LPCREATESTRUCT, CCreateContext *);
DECLARE_DYNCREATE(FrameWindow)
private:
/* The docs say: A CSplitterWnd object is usually embedded in a
parent CFrameWnd or CMDIChildWnd object. */
CSplitterWnd splitter_;
};
FrameWindow.cpp:
#include "FrameWindow.h"
#include "WindowView.h"
IMPLEMENT_DYNCREATE(FrameWindow, CFrameWnd)
FrameWindow::FrameWindow()
{
VERIFY(Create(NULL, _T("Show Styles"), WS_OVERLAPPEDWINDOW, CRect(10,
10, 1024, 768)));
}
BOOL
FrameWindow::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle, CWnd
*pParentWnd, CCreateContext *pContext)
{
/* If we execute CFrameWnd::LoadFrame() the program becomes very
unhappy... */
return TRUE;
}
BOOL
FrameWindow::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext *pContext)
{
const int rows = 1;
const int columns = 2;
/* A CSplitterWnd should be created in OnCreateClient() according to
the docs. */
VERIFY(splitter_.CreateStatic(this, rows, columns));
CRect rect;
GetClientRect(rect);
/* row = 0, column = 0 */
VERIFY(splitter_.CreateView(0, 0, RUNTIME_CLASS(WindowView),
CSize(rect.right - 400, 0), pContext));
/* row = 0, column = 1 */
VERIFY(splitter_.CreateView(0, 1, RUNTIME_CLASS(WindowView),
CSize(rect.right - (rect.right - 400), 0), pContext));
return TRUE;
}
As you can see I'm using the same view for each pane right now, that will
change when I get this problem sorted. WindowView is very simple, nothing
added at all at the moment. This practically my first docview program so I
guess it's something simple. Hope I posted enough information. Running
MSVC++ 8.0 SP1 on fully patched WinXP Pro.
