DDE reference
Overview
The Glink DDE interface will transfer data to other applications using the
standard Windows text format, OEM format or using the extensions to the
Windows character set used internally by Glink. (The Glink character set may be
inspected using A
LT+F9 when running Glink - it is a superset of the standard
set). To use this last character set you must obtain a clipboard format identifier
by using the RegisterClipboardFormat() call with the name
'GlinkFont'. The format identifier may then be used in DDE requests in
place of cf_Text.
An additional clipboard format is available for applications that need to transfer
data in a completely transparent way, and is obtained by specifying
'GlinkBinary' (this must first have been registered in the same way as
'GlinkFont'). This format does not rely on a null termination character, but
uses the first two bytes of the data to specify the length of the rest of the data.
This should be specified with the low order byte followed by the high order byte.
The 'GlinkBinary' format may be used both for data requests and for
pokes.
System Topic
Glink supports a System topic, set up in the normal way with SysItems,
Topics and Formats as available items. Note that SysItems and
SysPokes are available in the normal 'application' topic to give a list of
currently supported functions.
