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:

C#

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);
                               }


                           };

                       }

                   }
               }

Solution 1

this will end any MS Word, maybe this is a start :

C#

using System.Diagnostics;

...

C#

Process[] word_apps= Process.GetProcessesByName("winword");
foreach(var word_app in word_apps){
 word_app.Kill();
}

No, It is not what I need. When the window of the MS Word is closed, the button must be removed.

use a timer
and see when word_apps count is zero to remove button

TatsuSheva 19-Sep-16 10:52am

for each app there is a button are you sure that it will work ?

VisualBasic knows GetObject[^] method, which returns COM object or nothing (null).

[EDIT]
~~There's no C# equivalent method, unless you add a reference to Microsoft.VisualBasic (not recommended).~~

There is a C# equivalent to GetObject - Marshal.GetActiveObject[^].

Thank you, Richard for that valuable comment.

[/EDIT]

Please, follow the instruction in below article to resolve your issue:
A C# alternative for the Visual Basic GetObject function[^]

Note: didn't tested by myself!

How could I associate the button and the object together so that when I close my app the button will be removed ?

Maciej Los 14-Sep-16 12:45pm

It depends on many factors. If you call an instance of MS Word application, you have full control over that application. If not, you have to check (in some period of time, probably by using BackgroundWorker) if instance of MS Word application is open and keep a button visible till the application is opened.

yes I call an instance of MS Word like what is done in the code above.So I use instance of MS Word how I can associate with the button ?

TatsuSheva 14-Sep-16 12:55pm

For app like notepad, calculator, I used processId in order to associate with the button. Like this: private static Button FindProcessButton(long id,FlowLayoutPanel f1)
{
return f1.Controls.OfType<Button>().FirstOrDefault(c => GetProcessId(c) == id);
}

private static long GetProcessId(Control control)
{
if (control.Tag is long)
return (long)control.Tag;

return 0;
}
in the class I call it like this: var button = FindProcessButton(proc.Id, f1);

I can't figure out a solution... Some help please
