我正在尝试使用示例http://support.microsoft.com/kb/300606制作可调整大小的属性表。但是，我的代码中有几个错误，我不知道如何克服。我使用对话框上的类向导创建了属性表。我只需要文章中提到的re-size功能。任何帮助将不胜感激。

.cpp 类

    #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->dwFlags |= PSH_USECALLBACK;
        psh->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)->style |= (DS_3DLOOK | DS_SETFONT
                | WS_THICKFRAME | WS_SYSMENU | WS_POPUP | WS_VISIBLE | WS_CAPTION);
            break;
        }
        return nRes;
    }

.h 文件

#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

};

我不断收到这些错误。

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 '->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 '->pfnCallback' must point to class/struct/union/generic type
        type is ''unknown-type''

编辑 我根据http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2005-09/msg00585.html修改了DoModal函数；现在我得到了这个错误。

代码：

int CGeoSheet::DoModal() 
{
    // Hook into property sheet creation code
    m_psh.dwFlags |= PSH_USECALLBACK;
    m_psh.pfnCallback = XmnPropSheetCallback;// <--Error
    return CPropertySheet::DoModal(); 
}

错误：

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

您使用了 CWndResizer 类，并且可以调整属性表的大小。

在头文件中包含 cwndresizer 类和该类的对象。CWndResizer 调整大小；

在 cpp 文件中，您可以调整属性表中所有控件的大小。

BOOL 类名::OnInitDialog() {

CPropertySheet::OnInitDialog();
    BOOL ok = FALSE;
ok = resizer.Hook(this);
ASSERT(ok);

// IDC_POLYGONS_LIST 要调整大小的控件 id

ok = resizer.SetAnchor(IDC_POLYGONS_LIST,ANCHOR_LEFT|ANCHOR_TOP|ANCHOR_BOTTOM);
ASSERT(ok);
   bOk = resizer.SetParent("CS",IDC_STATIC_GROUPBOX2);
ASSERT(bOk);

}

该错误是因为在 .h 中您忘记将回调设置为静态

int CGeoSheet ::XmnPropSheetCallback(HWND hWnd, UINT message, LPARAM lParam);

应该

static int CGeoSheet::XmnPropSheetCallback(HWND hWnd, UINT message, LPARAM lParam);
