最近用BCG16.1做界面，程序由一个exe程序和一个dll程序，exe程序显示主界面，在主界面上有一个按钮，单击它调用dll界面，问题来了，单击按钮时出现debug assertion failed如图：

点重试后，进入wincore.cpp断点情况如下：

CObject* p=NULL;
		if(pMap)
		{
			ASSERT( (p = pMap->LookupPermanent(m_hWnd)) != NULL ||
					(p = pMap->LookupTemporary(m_hWnd)) != NULL);
		}
		ASSERT((CWnd*)p == this);   // must be us

		// Note: if either of the above asserts fire and you are
		// writing a multithreaded application, it is likely that
		// you have passed a C++ object from one thread to another
		// and have used that object in a way that was not intended.
		// (only simple inline wrapper functions should be used)
		//
		// In general, CWnd objects should be passed by HWND from
		// one thread to another.  The receiving thread can wrap
		// the HWND with a CWnd object by using CWnd::FromHandle.
		//
		// It is dangerous to pass C++ objects from one thread to
		// another, unless the objects are designed to be used in
		// such a manner.
	}

函数实现如下：在主界面中

ON_BN_CLICKED(IDC_BTN_OPENCFG, OnBtnOpenCFG)

然后通过OnBtnOpenCFG调用dll的导出函数

void CGOTODlg::OnBtnOpenCFG() 
{	
      HT_OpenCtrlPane();
	TClose();
}

在DLL中显示界面：

	CParamSheet paramSheet;
	paramSheet.DoModal();

CParamSheet类继承BCG库中的CBCGPPropertySheet类如下：

CParamSheet::CParamSheet(CWnd* pParentWnd)
	:CBCGPPropertySheet (IDS_CAPTION, pParentWnd)
{
	BOOL b32BitIcons = globalData.bIsOSAlphaBlendingSupport;
	
	if (globalData.m_nBitsPerPixel == 16)
	{
		// 32-bit icons in 16 bpp display mode
		// are correctly displayed in WinXP only
		
		OSVERSIONINFO osvi;
		osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
		::GetVersionEx (&osvi);
		
		b32BitIcons = (osvi.dwPlatformId == VER_PLATFORM_WIN32_NT &&
			(osvi.dwMajorVersion > 5 ||
			(osvi.dwMajorVersion == 5 && osvi.dwMinorVersion >= 1)));
	}

    SetLook (CBCGPPropertySheet::PropSheetLook_OutlookBar);//PropSheetLook_OutlookBar);
	SetIconsList (b32BitIcons ? IDB_SHEETICON32 : IDB_SHEETICON, 64);

	
	

	AddPage(&m_nModePage);
	AddPage(&m_nConfigPage);
	AddPage(&m_nAlignPage);
//	AddPage(&m_Page1);
	m_pPrtParam = CPrinterParam::Create();
	ASSERT(m_pPrtParam);
	

	if(PRO_SEGMENT == m_pPrtParam->GetProPrinterMode())
	{
		m_pTemplatePage = NULL;

		if(NULL != g_pTempLibInst) 
		{ 
			TEMPPROC_MODELPAGE ProcAdd = NULL; 
			
			ProcAdd = (TEMPPROC_MODELPAGE)GetProcAddress(g_pTempLibInst, TEMPFUNC[TEMP_MODELPAGE]); 
			
			// If the function address is valid, call the function.
			if(NULL != ProcAdd) 
			{
				m_pTemplatePage = (ProcAdd)(m_pPrtParam->GetSystemOfUnit()); 
				
				if(NULL == m_pTemplatePage)
					AfxMessageBox("Temp_CreateModelPageDlg Failed");
			}
			else
			{
				AfxMessageBox("Get Temp_CreateModelPageDlg Address Failed");
			}
		}
		
		AddPage(m_pTemplatePage);

	}

	m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}

CParamSheet::~CParamSheet()
{
	
	if(PRO_SEGMENT == m_pPrtParam->GetProPrinterMode())
	{
			
		if(NULL != g_pTempLibInst) 
		{ 
			TEMPPROC_DELMODELPAGE ProcAdd = NULL; 
			
			ProcAdd = (TEMPPROC_DELMODELPAGE)GetProcAddress(g_pTempLibInst, TEMPFUNC[TEMP_DELMODELPAGE]); 
			
			// If the function address is valid, call the function.
			if(NULL != ProcAdd) 
			{
				BOOL bRet = (ProcAdd)(); 
				
				if(FALSE == bRet)
					AfxMessageBox("Temp_DeleteModelPageDlg Failed");
			}
			else
			{
				AfxMessageBox("Get Temp_DeleteModelPageDlg Address Failed");
			}
		}
		
	}

	if(m_pPrtParam)
		m_pPrtParam->Release();

	
}


BEGIN_MESSAGE_MAP(CParamSheet, CBCGPPropertySheet)
	//{{AFX_MSG_MAP(CParamSheet)
	ON_WM_QUERYDRAGICON()
	ON_WM_SYSCOMMAND()
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CPrinterParamSheet message handlers



HCURSOR CParamSheet::OnQueryDragIcon() 
{
	return (HCURSOR) m_hIcon;

}

void CParamSheet::OnSysCommand(UINT nID, LPARAM lParam) 
{
	// TODO: Add your message handler code here and/or call default
	
	CBCGPPropertySheet::OnSysCommand(nID, lParam);
}

BOOL CParamSheet::OnInitDialog() 
{
	BOOL bResult = CBCGPPropertySheet::OnInitDialog();

	// Set the icon for this dialog.  The framework does this automatically
	//  when the application's main window is not a dialog
	SetIcon(m_hIcon, TRUE);			// Set big icon
	SetIcon(m_hIcon, FALSE);		// Set small icon
	
	this->CenterWindow();
	
	return bResult;
}

而我换成BCG15后，本来好了一段时间，现在又不行了，一样的错误，现在如果.exe程序用BCG16，dll程序用BCG15就没有那个debug assertion failed，百思不得其解，求指点迷津。

跟踪一下，看是哪里断言出错，我记得 CBCGPPropertySheet类 SetIconsList (b32BitIcons ? IDB_SHEETICON32 : IDB_SHEETICON, 64);的时候，如果图标个数与页数不一致会报一个断言错误

断言在这个函数的第一行出错，多谢你的指导，我去试下

BOOL CParamSheet::OnInitDialog() 
{
    BOOL bResult = CBCGPPropertySheet::OnInitDialog();
 
    // Set the icon for this dialog.  The framework does this automatically
    //  when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE);            // Set big icon
    SetIcon(m_hIcon, FALSE);        // Set small icon
     
    this->CenterWindow();
     
    return bResult;
}

我试了下，图标个数和页面搞成一样的也有这个错误

[孤客天涯]

那你跟踪一下是哪里出错， BCG 16.1是有源代码的

[langtaosha1238]

BOOL bResult = CBCGPPropertySheet::OnInitDialog();

就是这里出错了，CBCGPPropertySheet::OnInitDialog()是个虚函数，CBCGPPropertySheet继承CPropertySheet类，CPropertySheet继承CWnd类；也许是我跟得不对，能告诉我这么跟踪吗

[孤客天涯]

只要有BCG的源码就能跟进去呀

[langtaosha1238]

有源码，现在是CParamSheet.DoModal时，进入CBCGPPropertySheet::OnInitDialog()函数，然后就直接出现DEBUG assertion failde了，没有进入BCG源码

把BCG代码设置依赖关联起来一起调试
