With a series of helper, Delphi can also use the chain CodeNow. // For example, to extract 3.1415926 from 141 into an integer: var num: integer; begin num: = pi. tostring (). split (['. ']) [1]. substring (0, 3 ). tointeger (); // input.

Notes: 1. Many features of its parent class tscrollbox are also very useful, such: Memo1.usesmallscrollbars: = true; 2. A stack list management action is used internally. Now you can perform multiple Undo operations ). 3. A new struct

Each element in the Set occupies only one binary bit. A set of less than eight elements only needs one byte. First observe the size of the Set: Type tset1 = set of (A1, A2, A3, A4, A5, A6, A7, A8); {exactly corresponds to eight

The function in the expression is limited. For example, if I want to bind the length of the output text (for example, the length of the output edit1.text in label1), there is no corresponding function; This can be handled in the onassigningvalue

The data is merged through id2d1geometry. combinewithgeometry (), but id2d1simplifiedgeometrysink (parent object of id2d1geometrysink) is returned ); You need to add id2d1simplifiedgeometrysink to id2d1pathgeometry for use. Uses direct2d, d2d1;
