When working with files from Delphi you might want to display the size of a file to the user in a Explorer-like format where the file size is not displayed in bytes – but the display depends on the size of the actual file.

To most users “45678123 b” is confusing – where “43.56 MB” is much more user friendly.

Format Byte Size to String

A custom Delphi function, FormatByteSize, converts a byte value into a string that represents the number expressed as a size value in bytes, kilobytes, megabytes, or gigabytes, depending on the size.

Too Read The Previous Article Please Read This..
Abstract: Semaphores are used to coordinate multiple threads and processes. That semaphores provide multiple threads with simultaneous access to a shared resource is highlighted by the TFixedConnectionPool class described in this article.

Semaphores are like mutexes on steroids. Not only do they provide for blocking thread synchronization, but they permit two or more threads, up to some specified maximum number, to work concurrently with a shared resource. As a result, they are unlike most other synchronization objects, which typically provide access to one thread at a time. For an introduction to the creation and use of semaphores, read the preceding article in this series on the Borland Developer Network site by clicking here. Read the rest of this entry »

Abstract: Semaphores are like mutexes on steroids. Not only can they coordinate multiple threads and process, but they can permit more than one simultaneous lock. This article shows you how to use these useful objects in a multithreaded environment

Semaphores are powerful synchronization objects that, like mutexes (mutually exclusives), permit you to coordinate multiple threads and processes in your Delphi applications. Likewise, in multithreaded server environments, such as WebSnap, Web Broker ISAPI servers, and IntraWeb applications, semaphores provide a flexible mechanism for protecting shared resources.

Hello alldelphi.com users, we meet again today i want to show you some interesting snippet

Suppose you have a data-critical type of application where you would not want a non-authored user to work with the data. Such an application could automatically log out the current user if no user activity has taken place in a lengthy time.

To track a user’s idle time you could hook keyboard and mouse activity. Note, however, that installing a system-wide message hook is a very invasive thing to do and should be avoided if possible, since it will require your hook DLL to be loaded into all processes. Read the rest of this entry »
