Introduction

Windows CE 3.0 provides interprocess communication support with COM and MSMQ.

• 
  Two separate COM modules offer two different levels of COM support: a limited-feature, small-footprint module that provides interprocess calls and a free-threading mode, and a larger module that supports out-of-process calls, full-threading model support, and Distributed Common Object Model (DCOM). The DCOM module, with the exception of the security interfaces, is fully compatible with Windows NT version 4.0 Service Pack 3 (SP3).
  
• 
  Enhanced MSMQ support in Windows CE 3.0 provides independent client support for messaging applications. MSMQ for Windows CE is compatible with Windows NT and Windows 2000 Message Queuing Services.
