C#操作窗口類(句柄操作)

C#寫個類操作窗口（句柄操作）實現(xiàn)過程：過程一：找到當(dāng)前鼠標位置的句柄您的使用2個WinAPI（俺喜歡自己封裝下來用）：ViewCode[DllImport(

publicstaticextern,boolEntryPoint= )]GetCUrsorPos(outPointpt);[DllImport(

publicstaticextern,EntryPoint=IntPtrWindowFromPoint(Pointpt);)]//鼠標位置的坐標publicstaticPointGetCUrsorPosPoint(){PointP=newPoint();if(GetCursorPos(outp)){returnp;}returndefault(Point);}///<summary>///找到句柄///<∕summary>/// 坐標</param>///<returnsx/returns>publicstaticIntPtrGetHandle(PointP)

{returnWindowFromPoint(p);

}過程二：改變窗口的Text您的使用1個WinAPI:田日V■ C7ViewCode[DllImport( ,EntryPoint= )]privatestaticexternintSendMessage(IntPtrhWnd,intMsg,IntPtrWParam,string///<summary>///給窗口發(fā)送內(nèi)容///</summary>lParam);///句柄</param>/// 要發(fā)送的內(nèi)容<∕param>publicstaticvoidSetText(IntPtrhWnd,stringlParam){SendMessage(hWnd,WM_SETTEXT,IntPtr.Zero,lParam);}privateconstintWM_SETTEXT=0x000C;通過這個方法就能改變Text的值了。思考：如果俺把這個窗口的句柄記錄下來，下次不用鼠標獲取，直接就能改變值不蠻好的嘛。例如：我有個桌面系統(tǒng)老叫我輸入用戶名，密碼。我記錄用戶名和密碼的窗口句柄，然后改變他們的輸入值，這樣多省事。(只是舉例，不考慮安全性)問題：你會告訴我，窗口句柄的每次重建會變的呀，咋辦?；卮穑侯惷蛔冄?。過程三：您的準備一些工具吧，例如：句柄找類名呀，類名找句柄什么的等等，下面會用到一些WinAPIViewCode[DllImport(

句柄</param>///<returnsx/returns>publicstaticstringGetClassName(IntPtrhWnd){StringBuilderlpClassName=newStringBuilder(128);if(GetClassName(hWnd,IpClassName,IpClassName.Capacity)==0){thrownewException( );}returnlpClassName.ToString();}思考：遍歷桌面上所有的窗口，然后找類名，然后改他的Text,扯淡嘛,相同的類名太多了，找毛呀。實現(xiàn)：不僅記錄類名，而且記錄類名在父窗口出現(xiàn)的位置，然后通過桌面一層層找下來，最后找到這個句柄。(雖然不是太準，但是一般的還是能解決了，如果你有什么好方式一起研究)。過程四：實現(xiàn)一個WinHWND的類，可以把他的規(guī)則，他的父窗口類名，以及在父窗口中同類名出現(xiàn)的順序記錄下來，然后通過這些記錄的信息還原句柄。[+IEIt7'CJViewCodepublicclassWinHWND{publicIntPtrHWND{get;set;}publicstringClassName{get;set;}publicWinHWNDParent{get;set;}publicintInParentSequence{get;set;}privateWinHWND(){}publicWinHWND(IntPtrhWnd){this.HWND=hWnd;this.ClassName=GetClaSSName();this.Parent=GetParent();this.InParentSequence=GetInParentSeqUenCe();}privatestringGetClassName(){returnWinAPI.GetClassName(this.HWND);}privateWinHWNDGetParent(){if(WinAPI.GetParent(this.HWND)==null){thrownewException(
