If you are completely new to programming, this book is unlikely to be useful on its own. Nonetheless, it assumes little or no knowledge of Delphi specifically: taking an integrated approach, it tackles features that are new and not so new, basic and not so basic. In the process, it will describe in detail the nuts and bolts useful for almost any application you may come to write in Delphi. About the Kindle edition of Delphi XE2 Foundations Delphi XE2 Foundations is available in both printed and eBook versions.
RetVal := All4DigitStrings(['7631', '1573', '1630']); //True MatchesMask and TMask limitations Whether you use either MatchesMask or TMask directly, two significant limitations exist: you can’t turn off case insensitivity for ‘ordinary’ letters, and parsing is somewhat ASCII-centric. The second issue means case insensitivity actually disappears if you specify characters outside of the ASCII range. Thus, where MatchesMask('cafe', '*E') returns True, MatchesMask('café', '*É') returns False. Nonetheless, match criteria do support any characters within the ‘Latin-1’ range (meaning, characters than have an ordinal number according to the Unicode standard of 255 or below).
These count a surrogate pair as a single character, though at the cost of being a lot slower than naïve calls to Copy. StrUtils also has LeftStr, MidStr and RightStr functions, but since they are implemented merely as super-simple wrappers round Copy, you might as well use Copy directly if surrogates aren’t a concern, which they normally won’t be. Deleting, inserting and replacing sub-strings (Delete, Insert, StuffString, StringReplace) To delete a specified number of Char values from a specified position in a string, call the Delete procedure.
