Re: [Gambas-user] using sockets to send binay files
Thanks Olivier for your reply. I discovered last night binary files can be sent as text files if you uuencode on before sending and uudecode after files are received. uuencode and uudecode are unix standards commands (they are in Ubuntu repositories and in Mac OX too) The code you put in your mails only works with text files.

Hi, Is there some way to send binary files using gambas sockets? Reading and sending byte per byte is too much slow. I read old post from Benoit about this and I think it's no possible at this time. It's true? Regards, Ricardo Díaz Use the WRITE or the PRINT instruction. For example: PRINT #MySocket, File.Load(/path/to/myfile); Don't forget the ; at the end of the PRINT instruction, otherwise a newline will be added.
