    [RESOLVED] Unable to load dialog holding webbrowser control from MFC Dll

    Hello guys;
    I am having a problem trying to load a dialog (dialog was created using VC++ 6 Resource editor) that resides inside an MFC DLL. Why MFC? Well... there's the catch! Turns out I need this dialog to hold a MS WebBrowser ActiveX Control.
    The second requirement is that the calling program is (and has to remain) a plain Win32 App, so, this app will call the DLL holding the dialog and will show a browser in it.
    In order to make things easier, I developed a small class that encapsulates the DLL's functionallity. This part works fine, but I provide the code for it to explain myself better:

    /////////////////////////////////////////////
    class __declspec ( dllimport ) MyBrowser
    {
    public:
    MyBrowser ();
    virtual ~MyBrowser ();

    BOOL Show ();
    };
    /////////////////////////////////////////////

    The important part is actually the Show() method which I provide next:

    //implementation of MyBrowser::Show() inside DLL
    /////////////////////////////////////////////
    BOOL MyBrowser::Show ()
    {
    AFX_MANAGE_STATE ( AfxGetStaticModuleState () );
    CMyBrowserDlg dlg;
    int res = dlg.DoModal ();

    if ( res == IDOK )
    {
    }
    else if ( res == IDCANCEL )
    {
    }

    return FALSE;
    }
    /////////////////////////////////////////////

    Nothing special but a simple call to the dialog's constructor (which is generated by the VC++ wizard) and then...dlg.DoModal() !!!!!
    Turns out that the call to DoModal() fails (returns -1), but ONLY WHEN THE DIALOG HOLDS THE WEBBROWSER CONTROL!!!
    When I take the control out, DoModal() doesn't fail and the dialog shows perfectly!

    Please help me!
    Thanks in advance!
