DELPHI 禁止移动窗体

完整的代码如下：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    lbl1: TLabel;
  private
//声明静态过程
    procedure WMSYSCOMMAND(var msg:TMessage);message WM_SYSCOMMAND;
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
//禁止窗体移动(此处的Tform1修改成自己的窗体名）
  procedure TForm1.WMSYSCOMMAND(var msg: TMessage);
  begin
    if msg.WParam=SC_CLOSE then Close;
    if msg.WParam=SC_MOVE then msg.WParam:=0;
  end;

end.
