VB/WinAPI, (VB,Winsock) Extracting data from socket.

(VB,Winsock) Extracting data from socket.

Joseph Toulie #1 / 3	(VB,Winsock) Extracting data from socket. Hello, I'm developing a VB Client app that receives data from a server via Winsock. The Winsock server is developed in C++ and the Client in VB6 The VB client receives the following message from the server: numeric_field (1 byte) ---> maps to VB Byte datatype string_field (2 bytes) ---> maps to VB String datatype float_field (4 bytes) ---> maps to VB Single datatype These fields arrives as a single string, so the client receives 7 bytes. Is there a way to "extract" these data into simple VB variables? Thanks in advance Joseph

Alexander Kienzl #3 / 3	(VB,Winsock) Extracting data from socket. Sorry, it's LSet, not Let ! LSet mydata = winsockreceivebuffer RtlMoveMemory might be an alternative.
