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);

I thick i forget something.... but what ?
