* NOTE for Hydra (butchd 9/26/97): In comments below, substitute
|
|
*
|
|
* SOFTWARE\Citrix
|
|
*
|
|
* with
|
|
*
|
|
* SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server
|
|
*
|
|
* Here's a brief(?) summary of how the registry mapping works. The goal is
|
|
* that an administrator can install an application, and then all users can
|
|
* use it, without any per-user configuration. The current design is that
|
|
* the administrator puts the system into installation mode (change user
|
|
* /install), installs the application, and then returns the system to
|
|
* execute mode (change user /execute). There are hooks in the API's used to
|
|
* create keys and values in the registry (BaseRegCreateKey, BaseRegSetValue,
|
|
* BaseRegRestoreKey, etc), and the hooks create a copy of the registry keys
|
|
* created under \HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Install (both for the
|
|
* user specific keys and the local machine keys). The local machine keys
|
|
* are added so that if sometime in the future we need to know all of the
|
|
* registry values created by an application, there is a copy of them
|
|
* available.
|
|
*
|
|
* When a user starts a Win32 app for the first time, the app will open the
|
|
* keys it needs to query. If the key doesn't exist underneath
|
|
* HKEY_CURRENT_USER, there are hooks in the base registry API's to catch the
|
|
* error and then search underneath the Citrix/Install section to see if the
|
|
* key exists there. If the key exists in the install section, we copy the
|
|
* key, its values, and its subkeys to the current user's registry. This
|
|
* way we only have to hook opens, and not every registry API. This helps
|
|
* reduce the overhead associated with this registry mapping.
|
|
*
|
|
* Some apps (such as the office short cut bar) delete entries and need to
|
|
* recreate the entries themselves. When an app deletes a key and the
|
|
* system is in execute mode, we will set a value under the key indicating
|
|
* that we should only copy the key to the user once. What this currently
|
|
* means, is that if this is the only key being created, we won't create it
|
|
* when that flag is set. However, if we are creating this key because we
|
|
* created its parent, we will still create the key.
|
|
*
|
|
* The other part of the registry mapping support is that when a user logs
|
|
* in, userinit calls a routine (CtxCheckNewRegEntries) which checks if any
|
|
* of the system keys are newer than any of the corresponding user keys. If
|
|
* they are, the user keys are deleted (we're assuming that if the system
|
|
* key is newer, than the admin has installed a newer version of an
|
|
* application). This deleting can be disabled by setting a value under
|
|
* HKEY_LOCAL_MACHINE\Software\Citrix\Compatibility\IniFiles\xxx where xxx
|
|
* is the key name, and the value should be 0x48.
