Appendix E
Lists of Differences, APIs, and Interfaces

This appendix contains a list of implementation differences between COM for OpenVMS and Microsoft COM as well as a list of APIs and interfaces provided in this release of COM for OpenVMS.

E.1 Differences between COM for OpenVMS and Microsoft COM

The following sections list important implementation differences between COM for OpenVMS and Microsoft's COM.

E.1.1 Service Control Manager (SCM)

OpenVMS does not provide an equivalent to the Windows NT Service Control Manager. As a result, applications that depend on Server services (such as stop, start, pause, and resume) rely on the OpenVMS features that provide similar functionality (if the features are available).

For example, you would use the OpenVMS site-specific startup and shutdown command procedures to implement automatic starting of services at system startup and automatic shutdown of services at system shutdown. Service APIs such as RegisterServiceCtrlHandler, ChangeServiceConfig, and so on, are not provided on OpenVMS.

E.1.2 Server Application Stack Size

In COM for OpenVMS, server application functions run in the context of server threads. As a result, server functions have a limited stack space of 48 KB. If you require additional space for local variables or structures, you should allocate dynamic memory for local variables or structures.

E.1.3 Use of the "char" Datatype

OpenVMS and Windows NT translate the IDL base data type "char" differently.

OpenVMS translates the data type as MIDL_CHAR, which is defined to be CHAR, and further defined to be "char." The OpenVMS compiler by default takes this to be equivalent to "unsigned char;" in most cases they can be used interchangeably. The two are not the same---C++ treats them as different data types you specify them in class member definitions.

Windows NT translates the data type directly as "unsigned char." This causes conflicts with Visual C++, which treats the "char" datatype as equivalent to "signed char." As in OpenVMS, "char" is not the same as "signed char" in class member definitions.

There are two workarounds to this mismatch:

E.1.4 MIDL Compiler Version

The MIDL compiler supplied with COM for OpenVMS is based on Microsoft's MIDL compiler V3.00.44

E.1.5 Using DCOM$CNFG to Change Application Configuration Permission

Use the Application Security Submenu options 5 and 6 to change the OpenVMS Registry key permissions of some keys associated with an application. Option 5 and 6 affect the security settings of the following keys:

On Windows NT systems, the security settings of the subkeys under HKEY_CLASSES_ROOT\CLSID\{guid} are changed only if the existing security settings match the original settings of HKEY_CLASSES_ROOT\APPID\{guid}.

On OpenVMS systems, the settings of the subkeys are changed even if the existing settings do not match the original settings of HKEY_CLASSES_ROOT\APPID\{guid}.

Options 5 and 6 do not change the settings of all keys associated with an application. For example, options 5 and 6 do not affect the following keys:

To change the security settings of these keys, use the following procedure:

  1. From a Windows NT system, start RegEdt32.
  2. From the Registry menu, choose Select Computer and connect to the OpenVMS system that contains the OpenVMS Registry.
  3. Select the key associated with the application you want to change.
  4. From the Security menu, choose Permissions... and grant the user Full Control.
  5. Repeat the last two steps for each registry key associated with the application (see the list of keys described earlier in this section).

Note

HKEY_CLASSES_ROOT is an alias for HKEY_LOCAL_MACHINE\SOFTWARE\Classes. If you connect to the OpenVMS Registry from Windows NT using Regedt32 and you want to edit the HKEY_CLASSES_ROOT key, edit the HKEY_LOCAL_MACHINE\SOFTWARE\Classes key.

Appendix H
Glossary


class (registry class): Registry element attribute that allows you to store additional descriptive information with a registry key or subkey.

encapsulation: The process of updating or extending the life of existing application code by leaving most of the code and its functionality intact, while including new or updated code (usually in a different programming language) at key entry points.

For example, you might add a Windows graphical interface to a character-cell application by writing some Visual Basic code that collects information from a Windows client, then formats and submits the data to the existing character cell application as if the data had come from the character cell interface.

hive: A discrete set of keys, subkeys, and value entries contained in the registry.

in-process server: An application that is located on the same system as the requesting client. On Windows NT systems, in-process servers are usually implemented as DLLs. On OpenVMS systems, in-process servers are usually implemented as shareable images.

key (registry key): Registry element that contains information specific to the computer, system, or user.

out-of-process server: An application that is located on a different system than the requesting client. On Windows NT systems, out-of-process servers are usually implemented as .EXE files.

registry: A hierarchical database consisting of one or more files that stores configuration information about system hardware and software.

subkey (registry subkey): Registry element that is a child of a registry key. A registry key can have zero or more subkeys.

value (registry value): Registry element that is the entry or value for a registry key or subkey.

wrapper: See encapsulation.
