On the other hand, dynamic run-time packages contain all the routines, even those that your EXE doesn't use, while, when using statically-linked packages, the IDE will only include stuff that your EXE actually use.In the end, a statically-linked EXE can turn out to be smaller that a bare EXE and external BPLs.DPR file), while the forms (windows) are described in files with the DFM extension, ie. Here's a skeleton of a unit: Open a DOS box, compile the program with "dcc32console", and run the compiled as with "console.exe".In the empty form that shows up when starting Delphi, add a label and a pushbutton, double-click on the button, and add the following code to the Button1Click() routine: Hit F9 to run the application, and click on the pushbutton to see the text of the label change.The important point is freeing the object from memory, or your application will leak memory.There are three ways to handle this: Declare a variable, call the class' Create() method, and end with Free(), preferably in a try/finally structure: A second way is to use the With structure, and set the instance's owner as a form, so that, even if you forgot to call Free, Delphi will free the object from memory when it kills the parent form (Actually, you should NOT call Free, and let the owner free the instance from memory): Note that the time to dynamically create components with owners is much slower than that to create components without owners. Here's how to read each line of a tab-delimited text file, and save this into an SQLite database: At design-time, the best way to add radio buttons to a form is by first adding a radiogroup object, and modify its Items property to add radio buttons.
PAS) which contain source code, and are listed in a project (.
With D7 at least, Delphi's Message Dlg doesn't let you select a default button, which is unfortunate for critical choices.
You'll have to use Win32's Message Box() instead: When you add a control on a form at design-time, Delphi takes care of creating and freeing the object, but those tasks are your responsibility when creating objects dynamically, at run-time.
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.
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.
Moving a design package to another host requires copying the following files: BPL, DCP, possibly DCR resources files, hitting the Component Install Packages menu, and clicking on Add.
