I'm now using this code ('Data' is a string): ' Create data string. DataPointer = Alloc(8) Mem = Memory DataPointer For Read Write Mem.Begin Write #Mem, (Server.DateCurrent + Server.DateUTC) As Float Mem.Send 'Data = Read #Mem As Float Data = Read #Mem, 8 ' Send transaction. udp.Begin Write #udp, id As Byte Write #udp, 56 As Byte 'Write #udp, (Server.DateCurrent + Server.DateUTC) As Float Write #udp, Data, Len(Data) udp.Send The recipient gets the wrong value for 'Data' when it is converted back from a string to a float. It gets the correct value if I use the commented "Write #udp, (Server.DateCurrent + Server.DateUTC) As Float". Any ideas why I can't write the data stored at DataPointer to the string Data? In case anyone forgot, I need the data to be saved as a string so it can be stored in an outgoing network transaction queue, which is an array of transaction structures. The Data property of the structure stores arbitrary groups of variables so grouping them as a string is the most convenient method since there will be up to 255 different transaction types. -- Kevin Fishburne Eight Virtues www:http://sales.eightvirtues.com e-mail:sa...@eightvirtues.com phone: (770) 853-6271 ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerry® mobile platform with sessions, labs & more.
