The Debug Diagnostic Tool (DebugDiag) is designed to assist in troubleshooting issues such as slow performance, hangs, memory fragmentation or leaks, and crashes in any Win32 user-mode process.
The Debug Diagnostic Tool includes additional debugging scripts focused on Internet Information Services (IIS) applications, web data access components, COM+ and related Microsoft technologies.
DebugDiag 1.0 was released as part of the IIS Diagnostic toolkit and as a standalone tool. DebugDiag 1.1 is currently available as a standalone tool.
DebugDiag provides an extensible object model in the form of COM objects and provides a script host with a built-in reporting framework.
It is composed of the following 3 components; a debugging service, a debugger host, and the user interface.
The Debugging Service
The debugger service (DbgSvc.exe) performs the following tasks:
- Attach/Detach the host to processes
- Collect performance monitor data
- Implement HTTP ping to detect hangs
- Inject leak monitor in running processes
- Collect debugging session state information
- Shows the state of each rule defined
The Debugger Host
The Debugger Host (DbgHost.exe) hosts the Windows Symbolic Debugger Engine (dbgeng.dll) to attach to processes and generate memory dumps. It also hosts the main analyzer module to analyze memory dumps. Dbghost.exe has no dependency on the service ?DbgSvc.exe? and can be used separately.
The User Interface
The user interfaces (DebugDiag.exe and DebugDiagAnalysisOnly.exe) present an interface to analyze memory dumps, automate the creation of control scripts and show the status of running processes, including services.
It is composed of 3 views:
- Rules: Creates control script for the debugger host through a wizard. The script is located under scripts
- Advanced Analysis: Runs a selected ?Analysis Script? against one or more memory dumps.
- Processes: Shows status of running processes/services

GW Debug is a simple debugging application for Win32 software. It can be used in conjunction with the debug version of the DirectX SDK in order to trace DirectX calls made by the program.

A frustration in debugging in Access 2000 and later is the clunky rigmarole required to check/set error-trapping.
Youll have the opportunity to simplify the process. Ezy Debug is launched from the right-click popup menu in the code window of the Access VB Editor.
The applet provides quick access to the Access error-trapping settings in the code window, and once invoked it is available both in the Access Database and VBE window.
The current error-trapping setting is displayed and can be hanged on the fly...

Auto Debug for Windows is an auto-tracing utility of programs.
User can set breakpoints, this application will auto trace the target program and record the input and output of function call.
Therefore, the software can help programmer analysis errors, process inside the target program, especially help the programmer analysis the sequences and parameters of the function call.
