How to check if an MS Word is closed in C#

Question

I am doing an application in C# which open exe files like notepad calculator. So my aim is when I open an exe file like Word a button is created automatically and then when I close the Word app the button will be removed. Each app will have its own button when it is launched. I tried to do it but I have some issues with the closing of the app. Here is what I did:   var applicationWord =  new  Microsoft.Office.Interop.Word.Application();                     applicationWord.Visible =  true ;                  applicationWord.DocumentBeforeClose += DocumentBeforeClose;                            if  (applicationWord.Visible ==  true )                  {                                button =  new  Button();                          button.Image = Properties.Resources.word_80;                          PIC_Barre.Controls.Add(button);                          button.AutoSize =  true ;                           //     button.Tag = proc.Id;                           PIC_Barre.Controls.Add(button);                             foreach  (Process proc  in  Process.GetProcessesByName( WINWORD ))                      {                           if  (proc.ProcessName.Contains( WINWORD ))                          {                              proc.WaitForInputIdle();                              {                                  Thread.Sleep(500);                                  SetWindowPos(proc.MainWindowHandle.ToInt32()                                      ( int )SetWinPos_ZOrderOpt.HWND_TOPMOST                                      0 0 0 0                                      ( int )(SetWinPosFlags.SWP_NOSIZE |                                            SetWinPosFlags.SWP_NOMOVE));                              }                              button.Click += (s e) => { ShowWindowAsync(proc.MainWindowHandle ( int )ShowWindowCommands.Normal); };                              proc.Exited += (s e) =>                              {                                  var method = (Action)(() => PIC_Barre.Controls.Remove(button));                                   // button.Visible = false;                                    if  (button.InvokeRequired)                                  {                                      button.Invoke(method);                                  }                                    };                             }                         }                  }

Hi Jim Is your problem solved? I have tested my code it's creating a button as well removed when I close the word doc.

It doesn't create two buttons with the MS Word did you try it ?

Hi Jim Try the below code private void button1_Click(object sender EventArgs e) { _process = new Process(); _process.StartInfo.FileName = @Winword.exe; _process.EnableRaisingEvents = true; _process.Exited += new EventHandler(_process_Exited); _process.Start(); _button = new Button(); _button.Text = Ok; _button.Location = new Point(150 150); this.Controls.Add(_button); } private void _process_Exited(object sender System.EventArgs e) { var method = (Action)(() => this.Controls.Remove(_button)); // button.Visible = false; if (_button.InvokeRequired) { _button.Invoke(method); } }

Hi Jim Try the following codeIt's working fine for me public partial class Form1 : Form { Process _process; Button _button; public Form1() { InitializeComponent(); } private void button1_Click(object sender EventArgs e) { _process = new Process(); _process.StartInfo.FileName = (notepad.exe); _process.EnableRaisingEvents = true; _process.Exited += new EventHandler(_process_Exited); _process.Start(); _button = new Button(); _button.Text = Ok; _button.Location = new Point(150 150); this.Controls.Add(_button); } private void _process_Exited(object sender System.EventArgs e) { var method = (Action)(() => this.Controls.Remove(_button)); // button.Visible = false; if (_button.InvokeRequired) { _button.Invoke(method); } } }
