The library key selection window (displayed when the Select button is clicked) now automatically highlights the library key being used.


Print Preview Version 3.0.5 : Feature Note-127 27/05/1999

Button icons have been made consistent with rest of suite and a 1:1 zoom button added.


Window Management Version 3.0.5 : Feature Note-126 27/05/1999

All windows have been modified so that they do not obscure the main ERACS window when they are maximised. Should you find a window that does obscure it please let us know.


Viewing Listing Files Version 3.0.5 : Feature Note-125 27/05/1999

The window used to display listing files is now associated with an open network window and has been made non modal. This enables you to view a listing file for each network you have open and switch between a listing window and the network diagram. For example if you opened two windows on separate data states of the same network you could display the Loadflow listings of each state simultaneously.


Loadflow Parameter Defaults Version 3.0.5 : Feature Note-124 27/05/1999

A button labeled 'Default' has been added to the Loadflow Parameters tab of the network properties form. This button returns all controls on the tab to their default values.


Results Listing Window Version 3.0.5 : Feature Note-123 27/05/1999

Added a right button popup menu. This allows the standard editing functions to be performed on the data shown in the window. Please note that the changes made are not saved back in to the ERACS database.


Reinstating Deleted Or Modified Library Keys Version 3.0.5 : Feature Note-122 27/05/1999

When a library key is deleted or modified a copy of the original data is maintained so that it is still available to networks that were constructed before the key was deleted or modified. When a network is loaded that contains such keys appropriate warnings are issued. If an element that uses such a key is edited the library data is highlighted in Red. Up until now you could still use the data but could not reinstate the key. A button labeled 'Reinstate...' has been added to the library key selection window, which enables you to reinstate, deleted or modified keys. To reinstate a key, edit an element that uses a deleted or modified key. Press the Select button. In the bottom right hand corner of the window is the Reinstate button. Click Reinstate. A form displaying the library data is shown. If the key had been deleted then there is no need to change the key's name. If the key has been modified then you will have to give the key a unique name. Click the OK button and a new key will be added to the library and referenced by the element.
