    <p>I'm trying to make a re-sizable property sheet using the example <a href="http://support.microsoft.com/kb/300606" rel="nofollow">http://support.microsoft.com/kb/300606</a>. However I get several errors in my code which I don't know how to overcome. I created the property sheet using a class wizard on my Dialog. I only need the re-size function mentioned in the article. Any help will be appreciated.</p> <p>.cpp class</p> <pre><code> #include "stdafx.h" #include "Geometry.h" #include "GeoSheet.h" // CGeoSheet IMPLEMENT_DYNAMIC(CGeoSheet, CPropertySheet) CGeoSheet::CGeoSheet(UINT nIDCaption, CWnd* pParentWnd, UINT iSelectPage) :CPropertySheet(nIDCaption, pParentWnd, iSelectPage) { } CGeoSheet::CGeoSheet(LPCTSTR pszCaption, CWnd* pParentWnd, UINT iSelectPage) :CPropertySheet(pszCaption, pParentWnd, iSelectPage) { } CGeoSheet::~CGeoSheet() { } BEGIN_MESSAGE_MAP(CGeoSheet, CPropertySheet) ON_COMMAND(IDOK, OnOK) END_MESSAGE_MAP() // CGeoSheet message handlers void CGeoSheet::OnOK() { CPropertySheet::OnClose(); } // Overriding DoModal() allows us to hook our callback into // the prop sheet creation int CGeoSheet::DoModal() { // Hook into property sheet creation code AFX_OLDPROPSHEETHEADER* psh = GetPropSheetHeader(); psh-&gt;dwFlags |= PSH_USECALLBACK; psh-&gt;pfnCallback = XmnPropSheetCallback; return CPropertySheet::DoModal(); } // This function must be a STATIC member function. //Callback to allow us set the default window styles // for the property sheet int CGeoSheet ::XmnPropSheetCallback(HWND hWnd, UINT message, LPARAM lParam) { extern int CALLBACK AfxPropSheetCallback(HWND, UINT message, LPARAM lParam); // XMN: Call MFC's callback int nRes = AfxPropSheetCallback(hWnd, message, lParam); switch (message) { case PSCB_PRECREATE: // Set our own window styles ((LPDLGTEMPLATE)lParam)-&gt;style |= (DS_3DLOOK | DS_SETFONT | WS_THICKFRAME | WS_SYSMENU | WS_POPUP | WS_VISIBLE | WS_CAPTION); break; } return nRes; } </code></pre> <p>.h file</p> <pre><code>#pragma once // CGeoSheet class CGeoSheet : public CPropertySheet { DECLARE_DYNAMIC(CGeoSheet) public: CGeoSheet(UINT nIDCaption, CWnd* pParentWnd = NULL, UINT iSelectPage = 0); CGeoSheet(LPCTSTR pszCaption, CWnd* pParentWnd = NULL, UINT iSelectPage = 0); virtual ~CGeoSheet(); protected: DECLARE_MESSAGE_MAP() //{{AFX_MSG(CMyPropertySheet) // NOTE - the ClassWizard will add and remove member functions here. afx_msg void OnOK(); int CGeoSheet::DoModal(); int CGeoSheet ::XmnPropSheetCallback(HWND hWnd, UINT message, LPARAM lParam); //}}AFX_MSG }; </code></pre> <p>I keep getting these errors.</p> <pre><code>geosheet.cpp(49) : error C2065: 'AFX_OLDPROPSHEETHEADER' : undeclared identifier geosheet.cpp(49) : error C2065: 'psh' : undeclared identifier geosheet.cpp(49) : error C3861: 'GetPropSheetHeader': identifier not found geosheet.cpp(50) : error C2065: 'psh' : undeclared identifier geosheet.cpp(50) : error C2227: left of '-&gt;dwFlags' must point to class/struct/union/generic type type is ''unknown-type'' geosheet.cpp(51) : error C2065: 'psh' : undeclared identifier geosheet.cpp(51) : error C2227: left of '-&gt;pfnCallback' must point to class/struct/union/generic type type is ''unknown-type'' </code></pre> <p><b>Edit</b> I modified the DoModal function according to <a href="http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2005-09/msg00585.html" rel="nofollow">http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2005-09/msg00585.html</a>; and now I get this single error.</p> <p>Code:</p> <pre><code>int CGeoSheet::DoModal() { // Hook into property sheet creation code m_psh.dwFlags |= PSH_USECALLBACK; m_psh.pfnCallback = XmnPropSheetCallback;// &lt;--Error return CPropertySheet::DoModal(); } </code></pre> <p>Error:</p> <pre><code>geosheet.cpp(50) : error C2440: '=' : cannot convert from 'int (__cdecl *)(HWND,UINT,LPARAM)' to 'PFNPROPSHEETCALLBACK' This conversion requires a reinterpret_cast, a C-style cast or function-style cast </code></pre>

    1. COThe missing 'AFX_OLDPROPSHEETHEADER' and GetPropSheetHeader definitions mean you are missing some include. Look in the Microsoft-example which one you are missing.

    2. COThe function CGeoSheet ::XmnPropSheetCallback must not have a blank between CGeoSheet and the ::.<br>Also, it must be static.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
