+==== Avec les Wildcards (*/?) ====
+== IsWild ==
+Declaration: ''function IsWild(InputStr, Wilds: string; IgnoreCase: Boolean): Boolean;''
+IsWild compare InputString with WildCard string and return True if corresponds.
+IsWild example:\\
+There are possible masks and corresponding strings:\\
+* : >= 0 letters;\\
+*A : words with >= 1 letters and A at the end;\\
+A*A : words with >= 2 letters and A at the begin and end;\\
+A* : words with >= 1 letters and A at the begin;\\
+? : one letter.\\
+== FindPart ==
+Declaration: ''function FindPart(const HelpWilds, InputStr: string): Integer;''
+FindPart compares a string with '?' and another, returns the position of HelpWilds in InputStr.
+FindPart example:
+<code delphi>
+var P: Integer; Wild: string;
+begin
+  Wild := '?im';
+  P := FindPart(Wild, 'Let him go');
+  { here P = 5 }
+end;
+</code>
+== Dans TStringList ==
+Dans la propertie TStringList.Filter, on peut utiliser les Wildcards (a creuser...)
