Windows multi-value registry entries in BLPackages
Using the BLPackage editor, you can edit Windows multi-value registry entries.
When editing a Windows registry value of type REG_MULTI_SZ (a value that accepts multiple entries), each entry is displayed as a separate child node beneath the node for the registry value itself. For each child node, you can edit the name and change the Add or Delete action for that node.
The Data field for the registry value concatenates the names of all nodes and displays their names in encoded form. If the Multivalue property for the registry value is set to 1, the BLPackage uses the name set for each individual node. If the Multivalue property is set to 0, the BLPackage uses the collective name created by concatenating the names of all nodes.
When you use a BLPackage to add an entry to a registry value, the entry is added to the end of the list of entries. When you use a BLPackage to delete an entry from a registry value, the system deletes the first entry it encounters that matches the entry you have specified.
