Topic: the quick way of checking is any AutoCAD launched

[Andrey Bushman]

This is the quick way of checking is any AutoCAD launched (acad.exe or accoreconsole.exe) or not. I've checked my code for the usual AutoCAD 2009-2016 x64. But I haven't their x86 versions, I haven't older AutoCAD versions, and I haven't their vertical products, therefore I can't check my code for these versions.

Here is similar theme but with C++ code.

Code - C#: [Select]

I just use System.Diagnostics.Process
 

Code - C#: [Select]

1. Process.GetProcessesByName("acad")

[Andrey Bushman]

I just use System.Diagnostics.Process

I know about this way and I used it in my some programs. But it is possible to rename any EXE file into acad.exe and this code can't define such substitution.

Of course, any code also can to create such named Mutex . So my variant also is not a silver bullet, but he can't be deceived by simple renaming of any EXE-file.

[Andrey Bushman]

Also, I expected the name of the process is dinamically calculated from its command line. At this case it would be not gotten if the command line is empty... For checking this I wrote such test:

Code - C#: [Select]

1. using System;
2. using System.Diagnostics;
3. using System.Runtime.InteropServices;
4.  
5. using cad = Autodesk.AutoCAD.ApplicationServices.Application;
6. using Autodesk.AutoCAD.ApplicationServices;
7. using Autodesk.AutoCAD.EditorInput;
8. using Autodesk.AutoCAD.Runtime;

15.     {
16.         [DllImport("Kernel32.dll", CallingConvention = CallingConvention.Cdecl,
17.             CharSet = CharSet.Unicode, EntryPoint = "GetCommandLine" )]
18.         static unsafe public extern char* GetCommandLine();
19.  
20.         [CommandMethod("cmd", CommandFlags.Modal)]
21.         static unsafe public void Cmd()
22.         {
23.             Document doc = cad.DocumentManager.MdiActiveDocument;
24.             Editor ed = doc.Editor;
25.  
26.             // I expected the name of the process is dinamically calculated from
27.             // its command line. At this case it would be not gotten if the
28.             // command line is empty.
29.  
30.             // I check my assumption...
31.  
32.             ed.WriteMessage("Before command line errasing...\n");
33.  
34.             Process proc = Process.GetCurrentProcess();
35.             ed.WriteMessage("Process name: {0}\n", proc.ProcessName);
36.  
37.             char* cmdLine = GetCommandLine();
38.             String str_cmdLine = Marshal.PtrToStringUni((IntPtr)cmdLine);
39.  
40.             ed.WriteMessage("GetCommandLine: {0}\n", str_cmdLine);
41.  
42.             ed.WriteMessage("Command line args:\n");
43.             foreach (String arg in Environment.GetCommandLineArgs())
44.             {
45.                 ed.WriteMessage("\t{0}\n", arg);
46.             }
47.             ed.WriteMessage("==============\n");
48.  
49.             ed.WriteMessage("After command line errasing...\n");
50.  
51.             *cmdLine = '\0'; // Now the command line is empty
52.            
53.             str_cmdLine = Marshal.PtrToStringUni((IntPtr)cmdLine);
54.  
55.             // command line is empty now
56.             ed.WriteMessage("GetCommandLine: {0}\n", str_cmdLine);
57.  
58.             ed.WriteMessage("Command line args:\n");
59.  
60.             // command line is empty now
61.             foreach (String arg in Environment.GetCommandLineArgs())
62.             {
63.                 ed.WriteMessage("\t{0}\n", arg);
64.             }
65.             ed.WriteMessage("==============\n");
66.  
67.             proc = Process.GetCurrentProcess();
68.  
69.             // I see the process name IS THE SAME...
70.             // So, I was mistaken.
71.             ed.WriteMessage("Process name: {0}\n", proc.ProcessName);
72.         }
73.     }
74. }

The output:

Command: cmd
Before command line errasing...
Process name: acad
GetCommandLine: "C:\Program Files\Autodesk\AutoCAD 2009\acad.exe"
Command line args:
 C:\Program Files\Autodesk\AutoCAD 2009\acad.exe
==============
After command line errasing...
Process name: acad
GetCommandLine:
Command line args:

==============

So, I see I was mistaken.
