Free windows api hooking software for windows

WinAPIOverride32 will enable you to override/monitor all functions of a process. This can be done for API functions or executable internal functions.
WinAPIOverride is more than a standard API monitoring software.
It can break targeted application before or after a function call, allowing memory or registers changes; and it can directly call functions of the targeted application.
These features allows to fill the gap between classical API monitoring softwares and debuggers.
Main features:
- You can define filters on parameters or function result
- You can define filters on dll to discard calls from windows system dll
- You can hook functions inside the target process not only API
- You can hook asm functions with parameters passed through registers
- Double and float results are logged
- You can easily override any API or any process internal function
- You can break process before or/and after function call to change memory or registers
- You can call functions which are inside the remote processes
- All is is done like modules : you can log or override independently for any function

Do you want to feel the speed and flexibility of Windows API programming? Then this tool will help you to incorporate all the Window API 32-bit directly into your Visual Basic application.

JAMon API is a free, high performance, simple, thread safe, Java API that allows developers to easily monitor applications JAMon API (Java Application Monitor API) is a free, high performance, simple, thread safe, Java API that allows developers to easily monitor production applications.
JAMon was developed primarily for monitoring J2EE applications, however JAMon 1.0/2.0 can be used in any JDK 1.2 or higher environment, and JAMon 2.1 can be used in any JDK 1.4 or higher environment.
JAMon can be used in Servlets, JSPs, EJBs and Java Beans in various J2EE Application Servers (Sybases EAServer, and BEAs WebLogic, WebSphere?), and can also be used in other programming environments that can call Java code (ColdFusion, PowerBuilder, BroadVision, ...).
JAMon is particularly useful in multithreaded software like a database engine.

API to .NET Mapping Plugin maps common Win32API functions to their .NET CLR equivalents and helps the developer to search either MSDN online or Google for more information on either the Win32 function or its .NET counterpart.

RootKit Hook Analyzer is a security tool which will check if there are any rootkits installed on your computer which hook the kernel system services. Kernel RootKit Hooks are installed modules which intercept the principal system services that all programs and the operating system rely on.
If any of these system services are intercepted and modified it means that there is a possibility that the safety of your system is at risk and that spyware, a virus or other malware is active on your system. Kernel hooks are not necessarily bad, for system monitoring software and security tools often they are a necessary evil. However it is desired if kernel rootkit hooks are installed on your system that you can find out where they come from. This program will display all kernel services and the responsible modules for handling them, along with company and product information. If no hooks are active on your system it means that all system services are handled by NTOSKRNL.EXE, the principal base component of most Windows operating systems which is developed by Microsoft. All you have to do to find out what kernel hooks are installed on your system is press the Analyze button at the bottom of the screen. RootKit Hook Analyzer also allows you to view installed system modules and drivers with their base addresses as well as file and product information as well as the responsible companies.
New is the option to tets the quality of system hooks. If you have legitimate software installed which uses system call hooks, you can test if they are properly implemented by using the hook test function. This way you can see if hooking third-party system software may be responsible for random reboots and blue screens on your system.
The software is distributed as a free download. For more information visit http://www.resplendence.com/hookanalyzer
