    Hello @sedoerr,
    what do you mean by DialogBox?
    Do you mean a dialog?

    Best regards,
    Marcel

    Hi there,

    yes exactly. In my program, i have several visualizations defined as dialogs to give users the option to make inputs. And i need to detect if one of these dialogs is opened.

    Hey,
    there are a few ways to detect if a dialog was opened.
    You can e.g. add an additional input action on the same input type and call some ST Code.

      Hi Marcel,

      yes thats an option. But i have about 50 input actions which are calling a dialog. So it is a lot of work to use this way.

      I tried this way, but is am not sure if it is the right way:

      FUNCTION TEST : BOOL
VAR_INPUT
    sDialogName         : STRING;
END_VAR
VAR
    pstClientData       : POINTER TO VisuElems.VisuStructClientData;
    itfDialogManager    : VisuElems.IDialogManager;
    itfMyDialog         : VisuElems.IVisualisationDialog;
    variable:DWORD;
END_VAR

      VisuElems.VisuElemBase.g_ClientManager.BeginIteration();
pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient();

WHILE pstClientData <> 0 DO
itfDialogManager := VisuElems.g_VisuManager.GetDialogManager();
itfMyDialog := itfDialogManager.GetDialog(sDialogName);
pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient();
END_WHILE

    I found a solution for my problem:

    FUNCTION CheckDialogOpen : BOOL
VAR_INPUT
    sDialogName         : STRING;
END_VAR
VAR
    pstClientData       : POINTER TO VisuElems.VisuStructClientData;
    itfDialogManager    : VisuElems.IDialogManager;
    itfMyDialog         : VisuElems.IVisualisationDialog;
END_VAR

    //Prüfen ob Dialogfenster geöffnet
VisuElems.VisuElemBase.g_ClientManager.BeginIteration();
pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient();

WHILE pstClientData <> 0 DO
    itfDialogManager := VisuElems.g_VisuManager.GetDialogManager();
    itfMyDialog := itfDialogManager.GetDialog(sDialogName);
    CheckDialogOpen := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog,pstClientData,itfDialogManager);
    pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient();
END_WHILE
