Free debugging tool software for windows

You can use Debugging Tools for Windows to debug drivers, applications and services You can use Debugging Tools for Windows to easily debug drivers, applications and services on systems running Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows Server codename "Longhorn," as well as for debugging the OS itself.
Debugging Tools for Windows package is available in two versions: for 32-bit x86, native Intel Itanium and native x64 platforms.
The 64-bit versions of Debugging Tools for Windows allow you to debug both 32-bit and 64-bit user-mode applications running on 64-bit processors. Use this package to debug both the application and the WOW64 emulator.
System requirements:
- Microsoft Internet Explorer 5.0 or later.
- Approximately 25 MB of hard disk space.

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...

The Hotbasic debugger will help you to debug your applications faster than ever without any adding of debug subs in you code, this is done by the debugger automatically.
No files in your source folders all sources handles within the debugger directory.
Hotbasic Debugger will set and remove breakpoints and run the program to the breakpoint, very good when debugging big applications.
Main features:
- Step by Step debugging
- Breakpoint debugging
- Live variable values
- Debugging in include files selectable
- Debugging of GUI and Console Applications
- Auto reloading of source file if source is changed
- Individial resizeble windows for each function
- Possibility to save window state in normal and in debug mode

Visual Query Tool is a powerful, high-flexibility, end-user friendly universal tool for database querying, processing and maintenance - based on structured parameterized SQL command collections. It is compatible with all ODBC compliant databases.
VQT can be used as a stand-alone tool for database querying and reporting with multiple displaying and optionally automated exporting possibilities: form and browse view, html-based printable report, business graphic, dbf and text file, xml data-file - suitable for example for data-island technology.
How it works? After a preliminary pre-processing of tasks - replacing the formal parameter references with user-supplied values - Visual Query Tool executes the selected command, using standard ODBC connections. The result is displayed or saved immediately.
You as a designer can build protected, user-safe command packages with customized command sets and parameter pages deployed to unqualified end-users - the interface will speak your language through parameter page captions, descriptions and tool tips. It can be used as a stand-alone product or to extend the functionality of existing applications.
The professional edition enables iterative DBF processing and support an extensible Object oriented scripting language.
The available designer tools are: Structure Inspector, Visual Parameter page Designer, SQL Editor, Connection Manager, New Package Template Manager, Package Maintenance, simple debugging tools.
Documentation and tutorial samples are included the in standard install kit. Download from and activate a trial version for free at www.vqtool.com.
Due to its user-friendly interface, the learning curve is short and the deployment costs are at a low level. Connecting through widely accepted ODBC drivers, VQT is able to manage and process a very large scale of ODBC compliant SQL databases like Oracle, db2, MySQL and desktop databases like MS-Access, FoxPro or Clipper DBF tables.
