控件style你知我知

編輯:Delphi
 一般控件我可以通過給於我們的屬性設置,但我們不可能滿足這些屬性
  比如我們要edit1.text只能是數字,雖然我可以在edit.change監控,但
  其控件style已提供相應的style,下面是代碼----還有一些style自己
  試一下。
  var
    defstyle: dWord;
  begin
    defstyle := GetWindowLong(Edit1.Handle, GWL_STYLE);
    SetWindowLong(Edit1.Handle, GWL_STYLE, defstyle or ES_NUMBER)
  end;
