VC++,VC#,VB.NET中文版编码规范不断完善中

本文主要介绍了VC++语句语言/MFC中如下内容的剪贴板操作：1、文本内容的操作2、WMF数据的操作3、位图的操作4、设置应用自定义各式5、感知剪贴板内容的改变6、自动将数据粘贴到另一应用程式窗口一、文本内容的操作下面的代码示范了怎能将文本内容复制到剪贴板(Unicode编码的先转化为ASCII)：CString source;//文本内容保存在source变量中if( OpenClipboard() ){HGLOBAL clipbuffer;char * buffer;EmptyClipboard();clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1);buffer = (char*)GlobalLock(clipbuffer);strcpy(buffer, LPCSTR(source));GlobalUnlock(clipbuffer);SetClipboardData(CF_TEXT,clipbuffer);CloseClipboard();}下面的代码呈现了怎能从剪贴板上获得文本内容：char * buffer = NULL;//打开剪贴板CString fromClipboard;if ( OpenClipboard() ){HANDLE hData = GetClipboardData(CF_TEXT);char * buffer = (char*)GlobalLock(hData);fromClipboard = buffer;GlobalUnlock(hData);CloseClipboard();}二、WMF数据的操作在剪贴板上读写图象数据是非比寻常有用的功能，并且呈现起来也很简单。

下面的代码呈现了怎能将扩展图元文档复制到剪贴板：if(OpenClipboard());{EmptyClipboard();//创建图元文档DCCMetaFileDC * cDC = new CMetaFileDC();cDC->CreateEnhanced(GetDC(),NULL,NULL,"the_name");//调用绘图例程//关闭CMetafileDC并获得它的句柄HENHMETAFILE handle = cDC->CloseEnhanced();//复制到剪贴板SetClipBoardData(CF_ENHMETAFILE,handle);CloseClipboard();//删除dcdelete cDC;}下面的代码演示了从剪贴板获得图元文档并将其绘制到client DC上：if(OpenClipboard()){//获得剪贴板数据HENMETAFILE handle = (HENMETAFILE)GetClipboardData(CF_ENHMETAFILE);//呈现CClientDC dc(this);CRect client(0,0,200,200);dc.PlayMetaFile(handle,client);//关闭剪贴板CloseClipboard();}三、位图的操作位图的操作稍微复杂一点，下面那个例子呈现了怎能在剪贴板保存位图：if(OpenClipboard()){EmptyClipboard();CBitmap * junk = new CBitmap();CClientDC cdc(this);CDC dc;dc.CreateCompatibleDC( CRect client(0,0,200,200);junk->CreateCompatibleBitmap(&cdc,client.Width(),client.Height());dc.SelectObject(junk);DrawImage(&dc,CString("Bitmap"));//复制数据到剪贴板SetClipboardData(CF_BITMAP,junk->m_hObject);CloseClipboard();delete junk;}下面的代码呈现了怎能从剪贴板上获得位图数据：if(OpenClipboard()){//获得剪贴板数据HBITMAP handle = (HBITMAP)GetClipboardData(CF_BITMAP);CBitmap * bm = CBitmap::FromHandle(handle);CClientDC cdc(this);CDC dc;dc.CreateCompatibleDC( dc.SelectObject(bm);cdc.BitBlt(0,0,200,200,&dc,0,0,SRCCOPY);CloseClipboard();}四、设置并应用自定义各式应用RegisterClipboardFormat()参数，没出国疑问复制和粘贴任何你需求的数据TYPE。

比如咱们有以下唯一的数据TYPE：struct MyFormatDatalong val1;int val2;};咱们要把它复制到剪贴板，没出国疑问应用如下的代码：UINT format = RegisterClipBoardFormat("MY_CUSTOM_FORMAT");if(OpenClipboard()){MyFormatData data;data.val1 = 100;data.val2 = 200;HGLOBAL clipbuffer;EmptyClipboard();clipbuffer = GlobalAlloc(GMEM_DDESHARE, sizeof(MyFormatData));MyFormatData * buffer = (MyFormat数据*)GlobalLock(clipbuffer);//保存到内存*buffer = data;//保存到剪贴板GlobalUnlock(clipbuffer);SetClipboardData(format,clipbuffer);CloseClipboard();}读取数据应用以下代码：UINT format = RegisterClipboardFormat("MY_CUSTOM_FORMAT");MyFormatData data;if(Openclipboard()){HANDLE hData =GetClipboardData(format);MyFormatData * buffer = (MyFormatData*)GlobalLock(hData);data = *buffer;GlobalUnlock(hData);CloseClipboard();}五、感知剪贴板内容的改变经过win界面消息没出国疑问感知剪贴板内容也许除了改变，代码如下：//In your initialization code call:SetClipboardViewer(); //将咱们的程式添加到剪贴板观察链//In your message map add:ON_MESSAGE(WM_DRAWCLIPBOARD, OnClipChange) //添加Message handle//Which is declared as:afx_msg void OnClipChange();Finally implement:void CDetectClipboardChangeDlg::OnClipChange(){CTime time = CTime::GetCurrentTime();SetDlgItemText(IDC_CHANGED_DATE,time.Format("%a, %b %d, %Y -- %H:%M:%S"));DisplayClipboardText(); VC++,语言,实现,MFC,剪贴板,操作,实例,代码,

使用ILDASM.EXE工具！写了两个小程序进行测试，一个使用C#语言，另外一个使用VB.NET语言。
