Delphi updating tcomponent classes
For example 0.1 means there will be a point every 10% of the width of the line, 0.05 means there will be a point every 5% of the width of the line.
The Delphi language was formerly known as Object Pascal, and is an object-oriented version of the venerable Pascal language, combined by Borland with a Visual Basic-like RAD tool that lets you write fast GUI applications with no run-time, a very rich set of components (VCLs) that can be statically compiled into the EXE, and an encapsulation of most of the Windows API for easier access to the underlying OS. For more infos, read Delphi history from Pascal to Diamondback (Delphi 2005) by Zarko Gajic. FWIW, the main extras offered by the Enterprise version of Delphi 7 are Intra Web from ATo Zed (Framework component set for building web apps in a RAD manner), Rave Visual Designer (Visual reporting tool), Biz Snap (to create web services,) and Model Maker (UML stuff.) If you'd rather use the familiar TAB button to indent a whole block, install Two Desk's Castalia add-in to the IDE, or the free Cn Wizards (a.k.a. If you are running Delphi Pro and above, check out GExperts or Cn Wizards.
Components can be distributed either as Typically, commercial components are provided as binary files, but some can also be bought with source files. PAS or DCU files) can be added to an existing package, or to a brand new package through either File Install Component (when adding to an existing package, the default file is DCLUSR. A package file has the extension BPL, and is just a Borland-specific version of a DLL with added functions like Get Package Info Table(), ie.
routines that live in a file separate from the caller EXE, and that can be loaded dynamically when needed. EXE command-line Borland utility to display information containted in a BPL file.
Once installed, packages are listed in the Registry under HKEY_CURRENT_USER\Software\Borland\Delphi\ Components meant to be used in the IDE can only be installed as a package, ie.
Net framework were designed by the same person, Anders Hejlsberg. In October 2006, Borland relaunched its Turbo brand, and offers two versions: Explorer, which are free but doesn't allow installing third-party components, and Professional, which aren't. Borland Developer Studio) with just the Delphi for Windows32 personality.
As of April 2005, Delphi is available as Delphi 2005, a.k.a. Net applications, but you might be able to still get your hands on Delphi 7 (to write Win32, and Linux applications by using Kylix and the Qt widgets-based CLX component library instead of the Windows-only VCL widgets), or Delphi 8 (to get you started writing . If you just want to get started and learn Delphi, the Personal edition of Delphi 7 is all you need is love. If you are using the Personal or Standard edition, looks like the only way is to use the syntax, with no menu or keyboard shortcut available.
