Procedure: HistoryDlgProc ID:1
Purpose: Shows the history of the session. Only input lines
are shown. A double click in a line will make this
dialog box procedure return the index of the selected
line (1 based). If the windows is closed (what is
equivalent to cancel), the return value is zero.
Input: Normal windows callback
Output:
Errors:

Edit History:
15 Sept 2003 - Chris Watford [email protected]
- Added support for my StatementHistory structure
- Added the ability to export it as its exact entry, rather than
just a 1 liner
