　　⑵vc.里MFC进度条如何使用

　　⑶演练CProgress.进度条的主要功能进度条控制（ProgressControl主要用来进行数据读写、文件拷贝和磁盘格式等操作时的工作进度提示情况，如安装程序等，伴随工作进度的进展，进度条的矩形区域从左到右利用当前活动窗口标题条的颜色来不断填充。进度条控制在MFC类库中的封装类为CProgressCtrl，通常仅作为输出类控制，所以其操作主要是设置进度条的范围和当前位置，并不断地更新当前位置。进度条的范围用来表示整个操作过程的时间长度，当前位置表示完成情况的当前时刻。SetRange()函数用来设置范围，初始范围为-，SetPos()函数用来设置当前位置，初始值为，SetStep()函数用来设置步长，初始步长为，StepIt()函数用来按照当前步长更新位置，OffsetPos()函数用来直接将当前位置移动一段距离。如果范围或位置发生变化，那么进度条将自动重绘进度区域来及时反映当前工作的进展情况。进度条的对象结构进度条控制的建立方法CProgressCtrl&ProgressCtrl建立进度条控制对象结构Create建立进度条控制对象并绑定对象进度条控制类CprogressCtrl::Create的调用格式如下：BOOLCreate(DWORDdwStyle,constRECT&rect,CWnd*pParentWnd,UINTnID);其中参数dwStyle用来确定进度条控制的控制风格；参数rect用来确定进度条控制的大小和位置；参数pParentWnd用来确定进度条父窗口指针；参数nID用来确定进度条控制的控制符ID值。.进度条控制的类属性进度条控制的类属性包括设置进度条最大最小控制范围SetRange、设置进度条当前位置SetPos、设置进度条当前位置偏移值OffsetPos和设置进度条控制增量值SetStep。.进度条控制的操作方法进度条控制的操作方法主要是使进度条控制并重绘进度条的StepIt函数。进度条控制的应用技巧示例、利用应用程序向导AppWizard生成基于对象框的应用程序CProgDlg；、在对话框中设置进度条和静态文本控制，其ID分别为IDC_PROG和IDCPERCENT；在对话框初始代码中增加控制的范围和位置：在ProgDlg.h中设置两个数据成员，用来表示进度条的最大值和步长：//ProgDlg.hclassCProgDlg:publidialog{．．．．．．//其它代码public:intm_nMax,m_nStep;．．．．．．//其它代码}()在ProgDlg.cpp中设置初始状态BOOLCProgDlg::OnInitDialog(){Cdialog::OnInitDialog();．．．．．．//其它代码//TODO:AddextrainitializationhereCProgressCtrl*pProgCtrl=(CProgressCtrl*)GetDlgItem(IDC_PROG);pProgCtrl-》SetRange(,);//设置进度条范围．．．．．．//其它代码m_nMax=;m_nStep=;SetTimer(,,NULL);//设置进度条更新时钟returnTRUE;}()完善WM_TIMER消息处理，使进度条按照当前步长进行更新，同时完成进度条的百分比显示：voidCProgDlg::OnTimer(UINTnIDEvent){//TODO:AddyourmessagehandlerCProgressCtrl*pProgCtrl=(CProgressCtrl*)GetDlgItem(IDC_PROG);intnPrePos=pProgCtrl-》StepIt();//取得更新前位置chartest;intnPercent=(int)(((nPrePos+m_nStep)/m_nMax*+.);wsprintf(test,%d%%,nPercent);GetDlgItem(IDC_PERCENT)-》SetWindowText(text);Cdialog::OnTimer(nIDEvent);}

　　⑷CProgressCtrl*?pProgressCtrl;//获取或创建一个进度条//先演示动态创建pProgressCtrl?=?new?CProgressCtrl;pProgressCtrl-》Create(WS_CHILD|WS_VISIBLE|PBS_SMOOTH,?CRect(,,,),?AfxGetMainWnd(),?);?//?ID?=?//再演示获取pProgressCtrl?=?(CProgressCtrl?*)GetDlgItem(/*填写控件ID*/);//设置位置pProgressCtrl-》SetPos(...);

　　⑸c语言设计的系统中怎么设计进度条或者像是进度条的也行代码怎么写

　　⒅c#如何根据文件数量控制进度条

　　⒆说实话，关于进度条的解决方案很多，我暂且假定你在做Winform程序开发。

　　⒇如果你使用的StatusBar中的进度条的话，你可以不考虑多线程更新UI的问题，因为它本身已经在内部实现了外部线程更新UI控件的逻辑。但是如果你使用普通的Progressbar控件，那你就得自己处理这部分逻辑，因为控件只能在其所在的UI中更新，如果你想在其它线程中更新那你得用控件上的BeginInvoke方法，当然还有其它的解决方案。

　　⒉方案：利用线程池(Task.StartNew())

　　⒊你只要把btnProcess_Click中的代码替换为下面的代码即可：

　　⒋void?btnProcess_Click(object?sender,?EventArgs?e){????if?(isProcessRunning)????{????????MessageBox.Show(“A?process?is?already?running.“);????????return;????}????Task《string》.Factory.StartNew(()?=》?{???????????isProcessRunning?=?true;???????????return?Directory.GetFiles(“C:“,?“*“);????????})????????.ContinueWith(files?=》?{????????????string?filesResult?=?files.Result;????????????progressBar.Maximum?=?filesResult.Length;????????????Console.WriteLine(“The?Maximum?of?Progress?Bar?“?+?progressBar.Maximum);????????????return?filesResult;????????})????????.ContinueWith(files?=》?{????????????string?filesResult?=?files.Result;????????????Console.WriteLine(“The?files?count?“?+?filesResult.Length);????????????for?(int?n?=?;?n?《?filesResult.Length;?n++?)????????????{????????????????//?模拟拷贝文件过程?????????????????Thread.Sleep();????????????????Console.WriteLine(filesResult[n]);????????????????progressBar.Value?=?n?+?;????????????}????????})????????.ContinueWith(files?=》?{????????????MessageBox.Show(“Thread?pleted!“);????????????progressBar.BeginInvoke(????????????????????new?Action(()?=》????????????????????{????????????????????????progressBar.Value?=?;????????????????????}????????????));????????????isProcessRunning?=?false;????????});}

　　⒌当然，你也可以通过BackgroundWorker来做，可能更简单一点儿，原理相同，你可以搜索一下相关方案。

　　⒍注意，我只是通过一个Thread.Sleep()来模拟你Copy文件的逻辑。

　　⒎使用C#显示进度条，涉及到多线程编程，我只探索了使用BackgroundWorker和Thread的方法，下面分别列出。第一种：使用BackgroundWorker进行进度条控制BackgroundWorker对象有三个主要的事件：DoWork-当BackgroundWorker对象的多线程操作被执行时触发。RunWokerpleted-当BackgroundWoker对象的多线程操作完成时触发。ProgressChanged-当BackgroundWorker对象的多线程操作状态改变时触发。WorkerReportsProgress-如果想让BackgroundWorker对象以异步的方式报告线程实时进度，必须将该属性的值设为true。BackgroundWorker对象的ReportProgress方法用于向主线程返回后台线程执行的实时进度。实例代码一，控制主窗体中的进度条显示[csharp]viewplaincopypublicpartialclassForm:Form{///《summary》///后台线程///《/summary》privateBackgroundWorkerbkWorker=newBackgroundWorker();///《summary》///步进值///《/summary》privateintpercentValue=;publicForm(){Initializeponent();bkWorker.WorkerReportsProgress=true;bkWorker.WorkerSupportsCancellation=true;bkWorker.DoWork+=newDoWorkEventHandler(DoWork);bkWorker.ProgressChanged+=newProgressChangedEventHandler(ProgessChanged);bkWorker.RunWorkerpleted+=newRunWorkerpletedEventHandler(pleteWork);}privatevoidbtnStart_Click(objectsender,EventArgse){percentValue=;this.progressBar.Maximum=;//执行后台操作bkWorker.RunWorkerAsync();}publicvoidDoWork(objectsender,DoWorkEventArgse){//事件处理，指定处理函数e.Result=ProcessProgress(bkWorker,e);}publicvoidProgessChanged(objectsender,ProgressChangedEventArgse){//bkWorker.ReportProgress会调用到这里，此处可以进行自定义报告方式this.progressBar.Value=e.ProgressPercentage;intpercent=(int)(e.ProgressPercentage/percentValue);this.label.Text=“处理进度:“+Convert.ToString(percent)+“%“;}publicvoidpleteWork(objectsender,RunWorkerpletedEventArgse){this.label.Text=“处理完毕!“;}privateintProcessProgress(objectsender,DoWorkEventArgse){for(inti=;i《=;i++){if(bkWorker.CancellationPending){e.Cancel=true;return-;}else{//状态报告bkWorker.ReportProgress(i);//等待，用于UI刷新界面，很重要System.Threading.Thread.Sleep();}}return-;}}

　　⒏这个实现的方法很多，可以用代理，BackgroundWorker，Task，Thread等等，但原理差不多，就是开一个新线程让其执行耗时操作，过程中异步更新UI界面。
