I am using the code below to call outlook express

Thisform._Shellexecute.Shellexecute('mailto:' + ;
'?bcc=' + destino + ;
'&subject=' + RTRIM(Thisform.txtdsassunto.value) + ;
'&body=' + RTRIM(Thisform.edtdstexto.text))

The problem is: when the variable destino is greater than 400 bytes the outlook is not called.

The variable destino is a set of email address that comes from VFP table.

Is there a limitation of the lenght?
