move this line just below your class declaration:

PMAutomation powerMILL = new PMAutomation(Delcam.ProductInterface.InstanceReuse.UseExistingInstance);

and add another definition of the active session at the beginning of the button2_click event:

PMProject pSession = powerMILL.ActiveProject;
                Delcam.FileSystem.File importFile = new Delcam.FileSystem.File(@"C:\Users\*****\Desktop\HOLES.dgk");
                PMModel myModel = pSession.Models.CreateModel(importFile);

your problem is that the code inside of button2_click doesn't know what "pSession" is because it is being defined only in the other button's method.

This should work:

public partial class Form1 : Form
        {
            PMAutomation powerMILL = new PMAutomation(Delcam.ProductInterface.InstanceReuse.UseExistingInstance);

            public Form1()
            {
                InitializeComponent();
            }

            private void Form1_Load(object sender, EventArgs e)
            {

            }

            private void button1_Click(object sender, EventArgs e)
            {
                PMProject pSession = powerMILL.ActiveProject;
            }

            private void button2_Click(object sender, EventArgs e)
            {
                PMProject pSession = powerMILL.ActiveProject;
                Delcam.FileSystem.File importFile = new Delcam.FileSystem.File(@"C:\Users\*****\Desktop\HOLES.dgk");
                PMModel myModel = pSession.Models.CreateModel(importFile);
            }
        }

Hello.

First at all many thanks for your answer and help me nbaranowski.

Your solution is not correct at all.

Now when execute the code start automatically the Powermiil and not when press the button for start it.

But the second button works nice and import the file correctly.

Many thanks again.

Kindly regards.

You have the object set to "UseExistingInstance" so i assumed your session was already open.

You can just move another copy of the PMAutomation object into the button2_click to get what you want.

This is tested and works:

    public partial class Form1 : Form
    {
        

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {

            PMAutomation powerMILL = new PMAutomation(Delcam.ProductInterface.InstanceReuse.CreateNewInstance);

        }

        private void button2_Click(object sender, EventArgs e)
        {
            PMAutomation powerMILL = new PMAutomation(Delcam.ProductInterface.InstanceReuse.UseExistingInstance);
            PMProject pSession = powerMILL.ActiveProject;
            Delcam.FileSystem.File importFile = new Delcam.FileSystem.File(@"C:\Users\*******\Desktop\HOLES.dgk");
            PMModel myModel = pSession.Models.CreateModel(importFile);

        }
    }
}

Hi, what version of PowerMill are you running? Can you open task manager and see if pmill.exe is running when you get this error?

Hi, does it give a stack trace in the error report? That would help me work out which line it is failing on.

One thing to check, is it PowerMill you are running or PowerMill Viewer?
