vb如何获取任务管理器中应用程序列表

1. Visual Basic是一种由微软公司开发的包含协助开发环境的事件驱动编程语言。

2. 从任何标准来说，VB都是世界上使用人数最多的语言——不仅是盛赞VB的开发者还是抱怨VB的开发者的数量。

3. 源自于BASIC编程语言。VB拥有图形用户界面（GUI）和快速应用程序开发（RAD）系统，可以轻易的使用DAO、RDO、ADO连接数据库，或者轻松的创建ActiveX控件。程序员可以轻松的使用VB提供的组件快速建立一个应用程序。
   

4. 一个command 一个list。  list中第一个任务管理器，与最后一个Program Manager 过滤不掉 。

5. 如果想过滤的话 可以在窗体中添加一个判断，来移除。

6. 这是获取程序

    Process[] ps=Process.GetProcesses();  

   foreach (Process p in ps)  

   {

     if (p.MainWindowHandle != null)

   {  

   richTextBox1.Text += p.MainWindowTitle + "";

    }

    }
   

7.  #region 查找所有应用程序标题 private const int GW_HWNDFIRST = 0;

   private const int GW_HWNDNEXT = 2;        

   private const int GWL_STYLE = (-16);        

   private const int WS_VISIBLE = 268435456;

   {            

    List Apps = new List();            

   int hwCurr;              

   hwCurr = GetWindow(Handle, GW_HWNDFIRST);            

   while (hwCurr > 0)            

   {                  

   int IsTask = (WS_VISIBLE | WS_BORDER);                  

   int lngStyle = GetWindowLongA(hwCurr, GWL_STYLE);                

   bool TaskWindow = ((lngStyle & IsTask) == IsTask);                

   if (TaskWindow)

   int length = GetWindowTextLength(new IntPtr(hwCurr)); 

   StringBuilder sb = new StringBuilder(2 * length + 1);

   hwCurr = GetWindow(hwCurr, GW_HWNDNEXT);            

   } 

   return Apps;        

   }          

   #endregion

   调用  

   private void btReApp_Click(object sender, EventArgs e)        

   {              

   LvApp.Items.Clear();              

   List Apps = SystemInfo.FindAllApps((int)this.Handle);            

   foreach (string app in Apps)            

   {                  

   ListViewItem item = new ListViewItem(app);                

   LvApp.Items.Add(item);            

   }        

   }
