   Hello,
I am new user for CodeJock Control. I want add a CXTPWebBrowserCtrl in a CDialogEx.
i do that :

in .h :

	CXTPWebBrowserCtrl m_wndWebBrowser;

		DECLARE_DISPATCH_MAP();
	afx_msg BSTR OleGetAppPath();

in Cpp

void CShadowDlg::DoDataExchange(CDataExchange* pDX)
{ 	CDialogEx::DoDataExchange(pDX);
	DDX_Control(pDX, IDC_WEBBROWSER, m_wndWebBrowser);
         ...
         ...

BEGIN_DISPATCH_MAP(CShadowDlg, CDialogEx)
	DISP_PROPERTY_EX(CShadowDlg, "appPath", OleGetAppPath, SetNotSupported, VT_BSTR)
END_DISPATCH_MAP()

         ...
         ...

BOOL CShadowDlg::OnInitDialog()
{
	CDialogEx::OnInitDialog();
	m_wndWebBrowser.SetExternal(GetIDispatch(FALSE));

...
...

BSTR CShadowDlg::OleGetAppPath()
{
	WCHAR szAppPath[MAX_PATH + 1];
	::GetModuleFileNameW(NULL, szAppPath, _countof(szAppPath));
	return SysAllocString(szAppPath);
}

but i have an Exception like that:
Exception non gérée à 0x00007FFA5C8E49DE (ToolkitProEval2200vc170x64UD.dll) dans Shadow.exe : 0xC0000005 : Violation d'accès lors de la lecture de l'emplacement 0x0000000000000000.

on 	DDX_Control(pDX, IDC_WEBBROWSER, m_wndWebBrowser);

	Did you add the control to the dialog resource? If not, then IDC_WEBBROWSER does not exist.
