where am i mistaking here?

BOOL Cfirstw32mfcApp::InitInstance() { SetRegistryKey(_T("Natural_Demon")); ... .. .. } this works perfect ... the data retrieved from the registry is nicely update in the GUI BOOL Cfirstw32mfcDlg::OnInitDialog() { .. ... ... .. EDIT1 = AfxGetApp()->GetProfileString("Settings", "email", "your login"); EDIT2 = AfxGetApp()->GetProfileString("Settings", "password", "details here.."); return FALSE; // return TRUE unless you set the focus to a control } this works perfectly ... HRESULT Cfirstw32mfcDlg::OnButtonOK(IHTMLElement* /*pElement*/) { AfxGetApp()->WriteProfileString("Settings", "email", "hi"); AfxGetApp()->WriteProfileString("Settings", "password", "do"); return NULL; } but why doesn't this work ...? HRESULT Cfirstw32mfcDlg::OnButtonOK(IHTMLElement* /*pElement*/) { UpdateData(FALSE); AfxGetApp()->WriteProfileString("Settings", "email", EDIT1); AfxGetApp()->WriteProfileString("Settings", "password", EDIT2); return NULL; } if i do this ... UpdateData();, UpdateData(FALSE); or this UpdateDialogControls(this, FALSE); nothing works EDIT1 en EDIT2 are empty and the registry get's updated with empty values. where am i mistaking here? thnx in advance. kind regards, marco

Your Data Exchange handler function might not be set up correctly. The Data Exchange might be overwriting the data in your edit field controls, or no member variables are setup to write into the controls. It looks like you fill them in OnInitDialog, but you should do that in DoDataExchange.

You should be able to do all your data sets and retrievals within the DoDataExchange similar to something like this: void Cfirstw32mfcDlg::DoDataExchange(CDataExchange* pDX) { CDHtmlDialog::DoDataExchange(pDX); // data TO controls, means LOAD strings with your existing data or default values // you need to do this BEFORE the DDX_DHtml_ElementInnerText calls if( !pDX->m_bSaveAndValidate ){ EDIT1 = AfxGetApp()->GetProfileString("Settings", "email", "your login"); EDIT2 = AfxGetApp()->GetProfileString("Settings", "password", "details here.."); } // these calls presumably set or get the data from the controls into your string variables DDX_DHtml_ElementInnerText(pDX, _T("email"), EDIT1); DDX_DHtml_ElementInnerText(pDX, _T("password"), EDIT2); DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text1"), m_EDIT1); DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text2"), m_EDIT2); // data FROM controls, means SAVE data from the controls to your storage // you need to do this AFTER the DDX_DHtml_ElementInnerText calls if( pDX->m_bSaveAndValidate ){ GetElementText(_T("email")); AfxGetApp()->WriteProfileString("Settings", "email", EDIT1); GetElementText(_T("password")); AfxGetApp()->WriteProfileString("Settings", "password", EDIT2); } } If the DoDataExchange is correctly implemented, you don't even need to have the OnOK handler, since the DoDataExchange will be called for you (I am pretty sure) and you definitely don't need the Cancel, because the UpdatData (and thus DoDataExchange) is not called at all.
