Plug-in Installation

When a plug-in is installed, it will update the appropriate values in the Windows registry to indicate to the CA Gen toolset that the plug-in is available. Each plug-in application will add a folder into the Windows registry under "HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA Gen\xx\Plug-ins" key. For each key, the workstation creates a menu item under the "Plug-in" menu using the text found in the "MenuItemText" value. On a Windows 7 64-bit system, the registry entry is under "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\CA Gen\xx\Plug-ins".

Note: xx refers to the current release of CA Gen. For the current release number, see the Release Notes.

Each of the new plug-in menu items may be enabled or disabled using a combination of the registry key "EnableInDiagrams", the registry value "EnableSelectedObjectCount", and the registry key "EnableSelectedObjectTypes":

• If there are any diagram keys specified under the "EnableInDiagrams" key, then the menu item will only be enabled in the specified diagrams. If no diagram keys are specified under the "EnableInDiagrams" key, then the menu item may be enabled always, depending on whether or not the "EnableSelectedObjectCount" value is specified and (or) if any object type keys are specified under the "EnableSelectedObjectTypes" key.
• If the "EnableSelectedObjectCount" value is specified, then the menu item will only be enabled when the specified number of objects are selected. If the value is not specified, then the menu item may be enabled regardless of whether or not any objects are selected, depending on whether or not the "EnableSelectedObjectCount" value is specified and (or) if any object type keys are specified under the "EnableSelectedObjectTypes" key.
• If there are any object type keys specified under the "EnableSelectedObjectTypes" key, then the menu item will only be enabled in the given diagram when all the constraints for each object type are satisfied.

For example, the following registry values might be supplied by a registered plug-in application:

• MenuItemText = Switch Business System
• EnableInDiagram = DialogDesign
• EnableSelectedObjectCount = +

This set of registry values implies that the menu item "Switch Business System" will be added under the "Plug-in " menu. This menu item will only be enabled when the Dialog Design diagram is open and one or more objects are selected.
