I wrote a component, here is a snippet :
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
Db, FFDB, UGenericTable,hyperstr2, syncobjs;
TWorkPackage = class (TGenericTable)
this compiles without problem, D5 tells me that the package has been registered, but the componant is not added on the palette.
to avoid speculation I must add the the chosen description options are "desing and execution"
thanks for your help
