Open dialog via IEC code

    Hi all,
    I'm trying to open a custom dialog in my project (Codesys without success.

    I created a "Visualization" set as dialog with a couple of buttons and a rectangle with text.
    In my main page, when the user click a button, I have to perform some operations and then, if the operations are completed, I need to open this dialog.
    I tried with this code:

        dialogMan : VisuElems.IDialogManager; // Dialog manager
        openSaveDialogConfirm : VisuElems.IVisualisationDialog; // Reference to the custom dialog
        pClientData : POINTER TO VisuElems.VisuStructClientData;
        visuRect : POINTER TO VisuElems.VisuStructSimpleRectangle;
    // In my PLC_PRG
    IF dwOperationResult = 0 THEN // The file already exist. Ask for overwrite
        GVL.openSaveDialogConfirm := GVL.dialogMan.GetDialog('Dialogs.ConfirmDialog'); // Get the reference to the FileOpenSave dialog
        (* Check if the dialog exist, if so try to open it *)
        IF GVL.openSaveDialogConfirm <> 0 THEN
            GVL.visuRect := ADR(GVL.pClientData^.rClientRect);            
            xResult := GVL.dialogMan.OpenDialog(GVL.openSaveDialogConfirm,ADR(GVL.pClientData),TRUE,GVL.visuRect);

    All references to the objects are set, the variable xResult becomes true but the dialog is not displayed.
    I have no clue because the documentation is missing, can you help me?

    Thank you,

    Yes, you copied the example from codesys store; I did the same thing.

    Actually my question becomes: why should I use OpenDialog4? What are the other three functions used for?
