Hi Michael,

>I would like to distribute my app free as a promotional tool. I would like the app to not require a serial number for the first 30 days after which I would like the serial number to be required to run the app. How can I do it?

I haven't had time to do this yet, but see the Codemine GenCode.prg for how CodeMine can handle serial#'s. The help says "To require a serial number, set the serial number control's visible property (txtSerialNo.Visible) to .T., in page 1 of frmAppInstallDialog in source\appForms.vcx."

I would think you would set this to .F. for 30 days, then require the serial# by forcing a re-install of the app so the user is forced to enter the serial#.

Hope this gets you started in the direction.
