How to get Dialog window to show updated value ?
-
I have a derived Dialog class - CGeneralStatus that has a CString variable. If I set the string before I create the CGeneralStatus dialog it is displayed OK. When I set this string to different value the value in the window does not get changed. Even if I close and reopen the dialog window the value does not change. Any input is greatly appreciated ! ------------------------------------------------------------------------ Application code: void CFV3TaskMonApp::OnGeneralstatus() { if(IsShowingGeneral()) { HideGeneral(); } else { ShowGeneral(m_pMainWnd->GetActiveWindow()); } } void CFV3TaskMonApp::ShowGeneral(CWnd* parent) { if (!::IsWindow(*m_generalStatus)) { m_generalStatus->Create(IDD_GeneralStatus, parent); } m_generalStatus->GeneralChanged(); // update the string m_generalStatus->ShowWindow(1); } Code snippet to update the string value before calling ShowWindow(1): void CGeneralStatus::GeneralChanged() { CString out; out.Format("%d",m_app->m_numConnections); m_connAttempts = out; if (::IsWindow(this->GetSafeHwnd())) { ::PostMessage(this->GetSafeHwnd(),UWM_STATUS_UPDATEGENERAL,0,0); } }

CStringvariable, you did not indicate how it was being displayed. Assuming it was an edit or static control, you simply need an appropriate control variable in the dialog's declaration (e.g.,CEdit m_editnumConnections). When it comes time to display the value, simply callm_editnumConnections.SetWindowText().

My Dialog box only has the string variable (edit control - read only) box displayed, how do you declare a CEdit variable associated with that ? I added a CEdit m_editnumCOnnections compiled it and passed the new string value to m_editnumConnections.SetWindowText() and it cores not finding a main window handle. Thanks ! ----------- Code snip // Dialog Data //{{AFX_DATA(GeneralStatus) enum { IDD = IDD_GeneralStatus }; CString m_connAttempts; //}}AFX_DATA

DoDataExchange()? This is something that ClassWizard would do for you.
