TCESLogFile is based upon Riccardo 'Rico' Pareschi's (RicoSoft, component TLogFile. Rico based his component on an idea by Song Weng Sam and is a log file component. Needing such a component and not wanting to write one myself, I came across Rico's. For my needs, I needed a way to create a back-up of the log file when it, the log file, gets too large. I also needed one procedure to Open, Write and Close an error or other event in one operation. Lastly, since my error messages are all pretty standard, I added a design time property to enter a standard error message. I also noted a 'bug'. When the procedure CloseLogFile was run, the design time LogFile setting was messed up. I added a way to save its value so that the component would always remember the log file name that was entered at design time. I also rearranged the date and time stamps in the Write procedures. [more]

This Delphi 3 and 4 component, called CESRURunning, came about due to my programming need for a component to let me know whether or not another program or window is or was running. I use this component for demo applications that I do not want to run outside of the Delphi environment or other language, (if there really is any other programming language). It was also needed in several programs which COULD NOT run while one of my other applications was running. Lastly, the inverse is true whereby I needed to ensure that one of my applications was running before I allowed another application to start up. This was all to ensure proper hardware communication as well as to solve other unique problems. Whew!! That was a mouthful. Anyway, you can check for another application at anytime with events and a "manual" procedure as well. [more]
