Hi Akram
Two solutions:

1-Your activeX have a dll .
in the windows start type (or with run/n vfp command)
to register your.dll run the following command:

 
REGSVR32 your.dll  (with complet path)
 

To remove a .dll component registry entry

 REGSVR32 /u your.dll (with complet path)

a messagebox tells you if the dll registration is or no success.

2-You can include the dll or OCX of you activeX in the dialog box Options (vfp menu/tools/options/controls).
Yopu can add the composant here .it is registered automatically if you choose "as default/ok".
