c# winform 怎么给程序的按钮上也加上小盾牌图标

usingSystem.Runtime.InteropServices;

[DllImport("user32.dll")]
privatestaticexternIntPtrSendMessage(HandleRefhWnd,uintMsg,IntPtrwParam,IntPtrlParam);

///////////////////////////////////////////////////////////////////////
///<summary>
///Enablestheelevatedshieldicononthegivenbuttoncontrol
///</summary>
///<paramname="ThisButton">
///Buttoncontroltoenabletheelevatedshieldiconon.
///</param>
///////////////////////////////////////////////////////////////////////
privatevoidEnableElevateIcon_BCM_SETSHIELD(ButtonThisButton)
{
//Inputvalidation,validatethatThisControlisnotnull
if(ThisButton==null)
{
return;
}

//DefineBCM_SETSHIELDlocally,declaredoriginallyinCommctrl.h
uintBCM_SETSHIELD=0x0000160C;

//Setbuttonstyletothesystemstyle
ThisButton.FlatStyle=FlatStyle.System;

//SendtheBCM_SETSHIELDmessagetothebuttoncontrol
SendMessage(newHandleRef(ThisButton,ThisButton.Handle),BCM_SETSHIELD,newIntPtr(0),newIntPtr(1));
}

privatevoidForm1_Load(objectsender,EventArgse)
{
EnableElevateIcon_BCM_SETSHIELD(button1);
}

最后执行看下效果吧！

恩？盾牌为啥有点不一样呢，上面那个图标是server08上的，win7上应该是下面这样：

有错误的地方欢迎指出。
