+##More information
+**Application DialogVarInOut**
+
+This example shows how dialogs can be opened and how input values can be read and checked by an event handler.
+
+The event handler ``IEditBoxInputHandler`` is set in the main program ``PLC_PRG``. The method ``VariableWritten`` 
+is called after an input value is set. The range of the input value is checked by the method ``CheckValue`` of the 
+function block ``ControlFB``. The OK-Button is active if the variable ``pVar`` is less than 100. 
+Notice that the function block ``ControlFB`` is passed to the frame by the attribute ``VAR_IN_OUT_AS_POINTER``.
+
+**Application FileDialog**
+
+This example shows how file dialogs can be opened by program (ST) via the ``DialogManager``.
+
+The file filter and an instance of the function block ``Visu_FbFileListProvider`` is created in the program ``PLC_PRG``. 
+The function block ``Visu_FbFileListProvider`` is used by the dialog to list and filter files. The function 
+``OpenFileDialog`` sets the`` Visu_FbFileListProvider`` and opens the dialog. After selecting a file, the name 
+of the file is displayed in the visualization.
+
+**Application IECOpenDialog**
+
+The example shows how to open dialogs via the library ``Visu Utils``.
