status = RpcStringBindingCompose(	 // The RpcStringBindingCompose function creates a string binding handle.
NULL,
(RPC_WSTR)"ncacn_ip_tcp" ,
(RPC_WSTR)"192.168.1.2",
(RPC_WSTR)"2000",
NULL,
&stringBinding
);
if(status==RPC_S_OK) RhinoApp().Print("RpcStringBindingCompose = SUCCESS!!!\n");

RPC_BINDING_HANDLE ProgHandle;

status = RpcBindingFromStringBinding(
stringBinding,
&ProgHandle	 //server binding handle
);
if(status==RPC_S_OK) RhinoApp().Print("RpcBindingFromStringBinding = SUCCESS!!!\n");
if(status==RPC_S_INVALID_RPC_PROTSEQ) RhinoApp().Print("RpcBindingFromStringBinding = The protocol sequence is not valid.\n");


why is it that RpcStringBindingCompose returns "SUCCESS!!!" while RpcBindingFromStringBinding returns "The protocol sequence is not valid."

		(RPC_WSTR)"2000",

and this is what I get:

RpcStringBindingCompose = SUCCESS!!!
RpcStringBindingParse = SUCCESS!!!
ObjectUuid =
ProtSeq = ncacn_ip_tcp
NetworkAddr = 192.168.1.2
EndPoint = 2000
NetworkOptions =

RpcNetworkInqProtseqs = SUCCESS!!!
Protseq = ncacn_np
Protseq = ncalrpc
Protseq = ncacn_ip_tcp
Protseq = ncadg_ip_udp
Protseq = ncacn_http
RpcBindingFromStringBinding = The protocol sequence is not valid.


Please note the last line should read "RpcBindingFromStringBinding = SUCCESS!!!"
Why is my Protocol not valid.

Problem solved in another post!!!

Add 'A' to the end of the RPC functions to accept ANSI values (as opposed to wide values) and change the RPC_WSTR calls to RPC_CSTR and BADDA BING!
