Detect Autocad version - three questions

[alex_b]

Hi

The questions refer to an out-of-process program and a system with multiple Autocad versions installed.

Q1:  How do we detect the last run Autocad version?

       Somewhere between 2004 and 2008, the system registry doesn't point to the last run version any more, but points

       instead to AcLauncher.exe which, presumably' has the info.

       The question is: How to get the actual path to or the version of, the last-run Acad.exe?

Q2: How does one detect which Autocad version is currently running?

Q3: How does one detect the Autocad version of a .dwg file?

Quite a mouthfull, but with your help I hope to find the solutions.

Thanks

alex

Here is the answers to questions 2 and 3

    Public Sub getACAD()
        Dim ProcessList As System.Diagnostics.Process()
        Dim Proc As System.Diagnostics.Process

        ProcessList = System.Diagnostics.Process.GetProcesses()

        For Each Proc In ProcessList
            If UCase(CStr(Proc.ProcessName)) = UCase("acad") Then
                ' FOUND RUNNING COPY
            End If
        Next
    End Sub

Thank you Arcticad.

is2010() looks just what I need. I'll just translate it to C# and try it.

Re: your sub getAcad(): OK, we found a running acad, now how do we detect which version it is?

[Alexander.Rivilis]

Look at http://through-the-interface.typepad.com/through_the_interface/installation/ and check function GetAutoCADKey.

Also if you use function getACAD (by articad) you can get full path to acad.exe, i.e. Proc.MainModule.FileName

[alex_b]

arcticad, here is your function translated to C# and beefed-up a little:

public string[] getRunningAcadVersions()
		{
			List<string> result = new List<string>();
			Process[] processList = System.Diagnostics.Process.GetProcesses();
			foreach (Process proc in processList)
			{
				if (proc.ProcessName.ToString().ToUpper() == "ACAD")
				{
					FileVersionInfo versionInfo = proc.MainModule.FileVersionInfo;
					int versionMajor = versionInfo.FileMajorPart;
					int versionMinor = versionInfo.FileMinorPart;
					string version = versionMajor.ToString("X") + "." + versionMinor.ToString("X");
					result.Add(version);
				}
			}
			return result.ToArray();
		}

 May it help others.

Awesome.

I wasn't aware of the CurVer key.

I kept using Win32API.FindExecutable(".dwg") and it pointed to AcLauncher.exe.

Now it's OK

Thank you, Alexander, and Thank you, arcticad.

Alex! It is very old solution as far as I remember since AutoCAD R14.

Shame on me!
