[Quickfix-developers] trade client dialog access violation error

[mhassan <has...@gm...>]

i am developing a fix based GUI client in VS6, its a dialog 

when i got the success message in Application::onLogon(), i am trying to
update a label in the dialog but it gives error "Unhandled Exception
(MFC42D.DLL) 0xC0000005: access violation".


here is the piece of code i am trying in onLogon

     HWND hw=hWnd;
     CWnd* pWnd = CWnd::FromHandle(hWnd);
     
     LSEClientDlg* pDlg = (LSEClientDlg*) pWnd;
     ThreadFunction = LSEClientDlg::DlgFunction;
     ThreadFunction((LPVOID)pDlg, "Connected");

i am calling a static function of dialog and in the dialog method

void LSEClientDlg::DlgFunction(
LPVOID pObj, CString str)
{
    LSEClientDlg* pDlg = (LSEClientDlg*) pObj;
    pDlg->ud(str);

}


void LSEClientDlg::ud(CString msg)
{
        this->m_connection_status = msg ;
       UpdateData(FALSE);
            
}


the line 

this->m_connection_status = msg ;

 is getting the access violation error.

Any help very much appreciated.

thanks
m. hassan
