ĭelphi was originally developed by Borland as a rapid application development tool for Windows as the successor of Turbo Pascal. Delphi is known for its fast compilation speed, native code, and developer productivity. Database support is a key feature and is provided by FireDAC (Database Access Components). The visual forms designer has the option of using either the Visual Component Library (VCL) for pure Windows development or the FireMonkey (FMX) framework for cross-platform development. The code editor features Code Insight ( code completion), Error Insight (real-time error-checking), and refactoring. ĭelphi includes a code editor, a visual designer, an integrated debugger, a source code control component, and support for third-party plugins.

Procedure TForm1.ShowCustomer(const fields: array of string)
A procedure that displays a variable number of strings With Sarah do ShowCustomer([firstName, lastName, With John do ShowCustomer([firstName, lastName, Now show the details of both customers And then changing the first name to suit Set up John's sister similarly - simply copying the whole record This is where some of the danger of the with keyword comes.Ī structured data type - holding fields of dataĭownload this web site as a Windows program.Įxample code : Using the with keyword with a record structure It then looks at other data types, such as local variables, subroutine parameters etc. Within a With clause, Delphi tries to resolve these 'incomplete' references by looking at the immediate with target, and then any nested withs above. More disturbingly, it can create maintenance problems, where a code change can mean that the wrong target for the 'child' field referenced. However be warned that it can surprisingly make your code more difficult to read, especially when nesting with clauses. It simplifies the code by removing the need to prefix each referenced element with the complex variable name. The With keyword is a convenience provided by Delphi for referencing elements of a complex variable, such as a record or object.
