Excellent, that's an elegant solution. Thanks! Is it possible to read one or more values from the beginning of the packet normally, then read the remaining data into a single string? Something like this: Public Sub UDP_Read() Dim id As Byte Dim type As Byte Dim data As String Read #udp, id As Byte Read #udp, type As Byte Read #udp, data, Lof(udp) - 2 End If this works (and I don't see why it wouldn't), then everything is fixed. I can have a transaction array that can store any transaction type by saving the "payload" as a string and decoding it later with the *@() functions. -- Kevin Fishburne Eight Virtues www: http://sales.eightvirtues.com e-mail: sa...@eightvirtues.com phone: (770) 853-6271 ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
