It seems to me that only VFP controlls are affected by NODEFAULT.
On other hand there is cancel parameter in RecordClick() event and according to MMC help "Setting the Cancel parameter for the ButtonClick event to True prevents the default MCI command from being performed".

BTW, it's almost impossible to post replies today. After clicking on Preview or Send frame just goes white.

>In MMC, in my RecordClick() event, I verify if the file exist. If it is, I prompt the user to confirm overwriting it before continuing. If he says not, then, I want to get out of the event and cancel the default behavior. So, I put this in my code:
>

>This.Command='Close'
>
>IF FILE(This.FileName)
>
>   * If the file exist, we ask the user to overwrite it
>   IF ShowMes(GetMes('Multimed','FileExist'),36)=7
>      This.lRecord=.F.
>      This.Command='Open'
>      NODEFAULT
>      RETURN
>   ENDIF
>
>   ERASE (This.FileName)
>ENDIF
>
>This.Command='Open'
