我想把DateTimePicker的边框去掉，就像Edit一样，我试着在我继承的DateTimePicker控件中把Edit的设边框的代码加进去，属性是有了可没效果

Answer 1

这个基本上是没有办法解决的，因为它是系统画的，不过可这样来，系统画完后，我们再画上去覆盖它：unit MYDATETIMEPICKER;interfaceuses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ComCtrls;type
  TMYDATETIMEPICKER = class(TDateTimePicker)
  private
    { Private declarations }
    procedure WMPaint(var Message: TWMPaint); message WM_PAINT;
  protected
    { Protected declarations }
  public
    { Public declarations }
  published
    { Published declarations }
  end;procedure Register;implementationprocedure Register;
begin
  RegisterComponents('Standard', [TMYDATETIMEPICKER]);
end;{ TMYDATETIMEPICKER }procedure TMYDATETIMEPICKER.WMPaint(var Message: TWMPaint);
var
  BtnFaceBrush, WindowBrush: HBRUSH;
  dc : hdc;
  r : TRect;
begin
  inherited;
  DC := GetWindowDC(Handle);
   try
      BtnFaceBrush := CreateSolidBrush(GetSysColor(COLOR_BTNFACE));
      WindowBrush := CreateSolidBrush(GetSysColor(COLOR_WINDOW));
      try
         GetWindowRect(Handle, R);
         OffsetRect (R, -R.Left, -R.Top);
         FrameRect (DC, R, BtnFaceBrush);
         InflateRect (R, -1, -1);
         FrameRect (DC, R, BtnFaceBrush);
         InflateRect (R, -1, -1);
         FrameRect (DC, R, WindowBrush);
      finally
         DeleteObject (WindowBrush);
         DeleteObject (BtnFaceBrush);
      end;
   finally
      ReleaseDC(Handle, DC);
   end;
end;end.

把DateTimePicker缩小成只有一个下拉箭头，在旁边加个EDIT，看起来就想DateTimePicker平面化了。

Answer 3

考虑用三方控件，比如RZDATETIMEPICKER就可以

>>我想把DateTimePicker的边框去掉，就像Edit一样，
那你直接用個Edit 來顯示, 操作, 不行嗎??
旁邊加個按鈕就行!!
