VersionIndependentProgID Key
The values
associated with this key associate a ProgID with a CLSID. Used to determine the
latest version of an object application.
Registry Entry
HKEY_LOCAL_MACHINE\SOFTWARE\Classes
\<VersionIndependentProgID> = <Vendor>.<Component>
\CLSID = <CLSID>
\CurVer = <ProgID>
Value Entries
<Vendor>.<Component>
The name of
the latest version of the object application.
<CLSID>
The CLSID of
the newest installed version of the class.
<ProgID>
The <ProgID>
of the newest installed version of the class.
Remarks
The format or
the <VersionIndependentProgID> is <Vendor>.<Component>,
separated by periods, no spaces, and no version number. The version-independent
ProgID, like the ProgID, can be registered with a human readable name.
Applications
must register a version-independent programmatic identifier under the
VersionIndependentProgID key. The <VersionIndependentProgID>
refers to the application s class, and does not change from version to version,
instead remaining constant across all versions, for example, Microsoft Word
Document. It is used with macro languages and refers to the currently installed
version of the application s class. The <VersionIndependentProgID> must
correspond to the name of the latest version of the object application.
The <VersionIndependentProgID>
is used when, for example, a container application creates a chart or table with a toolbar button. In
this situation the application can use
the <VersionIndependentProgID> to determine the latest version of
the needed object application.
The <VersionIndependentProgID>
is stored and maintained solely by application code. When given the
VersionIndependentProgID, the CLSIDFromProgID28Q7N_ function returns the CLSID of the current
version.
You can use CLSIDFromProgID
and ProgIDFromCLSID
to convert between these two representations.
You can use IOleObject::GetUserType or OleRegGetUserType to change the identifier to
a displayable string.
If A custom
handler is not used, the entry should be set to OLE32.DLL, as shown in the
following example.
HKEY_-CLASSES_ROOT\CLSID\{ 00000402-0000-0000-C000-000000000046}
\InprocHandler = ole32.dll
In addition
to the preceding registry entry, you should add the following corresponding
entry under the CLSID
key:
\CLSID
\<CLSID> = <human readable name>
\<VersionIndependentProgID> = human readable name
