I think you have a typo:

CreatePipe(&handles[h_Child_StdOut_Read], &handles[h_Child_StdOut_Write], &sa, 0);

CreatePipe(&handles[h_Child_StdIn_Read], &handles[h_Child_StdIn_Write], &sa, 0);
SetHandleInformation(handles[h_Child_StdIn_Read], HANDLE_FLAG_INHERIT, 0);

SetHandleInformation(handles[h_Child_StdIn_Write], HANDLE_FLAG_INHERIT, 0);

that's also what they do at the MSDN example.
