ID: Q99807

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) 3.1

SUMMARY

The Windows Program Manager supports a dynamic data exchange (DDE) command- string interface that allows other applications to create, display, delete, and reload groups; add, replace, and delete items from groups; and to close Program Manager.

PMDDEML is a file in the Microsoft Software library that demonstrates how to use this Program Manager DDE command-string interface using the Dynamic Data Exchange Management Library (DDEML) introduced in Microsoft Windows version 3.1.

PMDDEML demonstrates only a small subset of the command-strings supported by Program Manager. The commands demonstrated by PMDDEML include:

CreateGroup
ShowGroup (both minimize and restore)
DeleteGroup

The other command-strings supported by Program Manager can be easily implemented in a manner similar to those commands demonstrated by PMDDEML.

The DDEML functions demonstrated by PMDDEML include:

DdeInitialize
DdeUninitialize
DdeConnect
DdeDisconnect
DdeCreateStringHandle
DdeFreeStringHandle
DdeClientTransaction

To use PMDDEML, run it and select the Shell Commands menu. Choose the Create "Sample Group" menu item. This will create a new program group (if one does not already exist) in Program Manager. Once the sample group is created, the group can be minimized, restored, or deleted by selecting the appropriate menu item in PMDDEML.
