Javadraw.exe MSMQ Java Drawing Sample Using SafeArrays

ID: Q176817

The information in this article applies to:

Microsoft Message Queue Server version 1.0

SUMMARY

The JavaDraw sample demonstrates how to implement a distributed drawing application using the Microsoft Software Development Kit (SDK) 2.0 for Java and Microsoft Message Queue Server (MSMQ) ActiveX components. The sample code sends and receives MSMQ messages that store drawings using Safearrays, character data as strings, and a "clear screen" message to both the sender and receiver.

The sample also demonstrates how to handle MSMQ ActiveX Events in Java.

and then click How to use the Microsoft Download Center. The sample prepares and sends one message for the entire stroke (drawing between mouse-down and mouse-up). It demonstrates an object-oriented approach that sends and receives different data types using Java. NOTE: In order to compile the sample code, you must use the latest Java compiler included in SDK 2.0. Before you build the sample, run the JActiveX tool on MSMQ type library (Mqoa.dll) to generate Java wrapper classes for MSMQ ActiveX components.
