Objects are dynamically allocated blocks of memory whose structure is determined by their class type. Each object has a unique copy of every field defined in the class, but all instances of a class share the same methods. Objects are created and destroyed by special methods called constructors ...
When inherited has no identifier after it, it refers to the inherited method with the same name as the enclosing method. In this case, inherited takes no explicit parameters, but passes to the inherited method the same parameters with which the enclosing method was called. For example, 当inher...
I think those features were also available in Delphi 8 and 2005. Main guideline: if you're in doubt, use a class. For the rest you have to understand the main difference: Class Objects are always used through a reference, and are created by calling a Constructor. The memory ...
Visualizes the structure of the JSON objects in a treeview; Generates complete delphi unit (declaration and implementation), based on the JSON string input; Automatically prefixes reserved Delphi words with "&" (ampersand); Support for JSON string that contains empty Array; ...
In Java there are various predefined stream classes that provide filters for other stream classes. The filter classes essentially "wrap" the streams they operate on and can often be applied to further filters. This article demonstrates how we can do this in Delphi in a way that is extendable ...
string at the position indicated byIndex. Index gives the position of the string associated with the object, where 0 is the first string, 1 is the second string, and so on. If a descendant ofTStringsdoes not support theObjectsproperty, reading this property returns nil (Delphi) or NULL (...
Private data in an object are hidden in a private area with internal access only. Users or other objects outside this object are prohibited from accessing the private data. Due to inheritance, a superclass can be extended to different subclasses. Each of the extended subclasses can “override...
Dispose objects in C# Disposing singleton class Dividing smaller number by a larger number yields a 0? DLL looking for wrong version DllImport and ref parameters DllImport Relative path in a Class Library Do I need to set this object to null to avoid a memory leak? Do i really need business...
Remaining 0xC bytes are left for object members, and we have to find them. We should notice that objects cannot be created without any reason, as well as that members can be filled either in constructor (fully or partly), or after creating by Set-methods. In TList constructor, it is ...
This topic emphasizes working with documents and views. It explains: How to write a form-based application using a CRecordView or CDaoRecordView object as the main view on your document. How to use recordset objects in your documents and views. Other considerations. For alternatives, see MFC:...
