This is a RAD Studio wizard / expert / plug-in which allow you to right click on an identifier in the code editor and add a breakpoint which contains a CodeSite.Send() evaluation expression so you can debug code with CodeSite without having to alter the underlying code (useful for debugging RTL and the VCL).

Every application should have a Splash screen and an About dialog. This component makes it as easy as dropping it onto your main form and calling a couple of methods. If you set VersionInfo in your Project Options, then most properties are automatically picked up. Two methods: SplashAbout1.ShowSplash (in form1.create method) and SplashAbout1.ShowAbout. No bloat: Windows are created on-the-fly and destroyed on close. OptionalIcon can be multi-resolution Set OptionalIconSize and the best available resolution/size will be displayed in Splash and About dialogs. Debug Logging available. Compile the /demo project to see what it can do Debug Logging (set DebugMode = TRUE) Windows and Linux.

This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .
Logging component for Delphi and Lazarus. Version 3.3 (02-05-2019) Multithreaded, object oriented, buffered safe. The log file will be correctly written to disk, even if your application crashes. The logging/parsing/formating and optionnal visual feedback work don't consume your main thread's time. Logging environment to support debugging. Easy-to-use strings formating capabilities. Update of Olivier Touzot's HotLog component 2004,2005. Many Thanks to Olivier.
. Delphi A simple but effective visual log control/library. The programmer can send messages to a log window from anywhere in his code. The Log window can be set to automatically pop up when an error message is sent to it. Depending on the chosen verbosity level of the log see the Verbosity property low-level messages like verbose/debug messages are shown or not. Contains: Non-visual log TRamLog Visual log TRichLog
A single fact determines the starting point of configuration, and that fact can be the same regardless of whether the software is running standalone under a logged-in user's account, or launched from another program with debugger access, or as a service or daemon, or even as a component within a dynamically linked library.
