System Debugging Log Application allows you to display messages produced by the debugging version of Windows, even if you are not running a debugger and if you do not have a debugging terminal. It even makes it possible for you to see some errors when it is running with the retail version of Windows. DBWIN.EXE allows you to control the output of specific varieties of messages. It also includes a feature that makes it possible for you to force memory-allocation errors, as an aid in testing the robustness of your application.
For information about the options you can set by using System Debugging Log Application, see Chapter 3, “Creating Windows Applications.”
