PC-DMIS Application Events via C#

[CodeWarrior]

So through the process of improving my app for automating pc-dmis I have undertaken the task of converting parts of my app from vbscripts to all C# code. When "interacting" with pc-dmis in previous versions, I would call the vbscripts to automate pc-dmis and wait for the script to finish before doing anything else.

Through converting my code in vbscripts to c# I have come across the problem that I don't know how to handle application events in c#. I am having trouble matching the syntax differences between vbscripts and c#.

The application event in particular i'm looking to handle is the "IsMachineConnected" event during startup of pc-dmis.

So if anyone has an example or input they'd like to share, I would greatly appreciate it.

Here is my working code to launch pc-dmis:

Using PCDLRN;

public void pcdLaunch() 
{ 
Type PCDRLN_Application = null; 

object PCDObj = null; 

PCDLRN.Application PCDApp = null; 

try 
{ 
PCDRLN_Application = Type.GetTypeFromProgID("PCDLRN.Application"); 

PCDObj = Activator.CreateInstance(PCDRLN_Application); 
} 
catch (System.Exception em) 
{ 
MessageBox.Show(em.Message); 
} 

PCDApp = new PCDLRN.Application(); 

PCDApp.OperatorMode = true; 

PCDApp.Visible = false; 
} 

TIA

Reference the Interop.Pcdlrn library and type similar to the following... (minus the class stuff).

using PCDLRN;

namespace SmartPattern_PcdApp
{
	public partial class Form1 : Form
	{
		// Globals
		ArrayList CmdItems = new ArrayList();
		PcDmisCls oPcdApp = new PcDmisCls();

		public Form1()
		{
			InitializeComponent();
		}


		private void Form1_Load(object sender, EventArgs e)
		{			
			PartProgram part = oPcdApp.Part();
			EditWindow ew = oPcdApp.editWindow;			

			oPcdApp.application.ApplicationEvents.OnSavePartProgram += new IApplicationEvents_OnSavePartProgramEventHandler(onSavePart);
			part.OnAddObject += new IPartProgramEvents_OnAddObjectEventHandler(addedObject);			

			part = null;
			ew = null;			
		}

		// Triggers when part is saved...
		void onSavePart(PartProgram prg)
		{
			// what do I put here?
			MessageBox.Show("Part Saved!");
		}

		// Triggers when an object is added
		void addedObject(Command cmd)
		{
			MessageBox.Show("Item: " + cmd.ID + " was added!");

			// Create cmds in C
		}
		}

Good source for C#: https://www.pcdmisforum.com/forum/pc...p-2010-express

Had the please of speaking with that man.... he's a LEGEND!

I did not come across anything for IsMachineConnected, have you used that before?

[CodeWarrior]

Thank you I will look into this and report back. For the "IsMachineConnected" I meant "OnMachineConnected" sorry for the typo there

[CodeWarrior]

Kp61dude! I've gotten your part program save example to work perfectly, I just have to test the "OnMachineConnected" event when I have a few moments with the CMM. I'll update this when I have a complete solution.

That was a very interesting thread to read through, impressive work by him. Don't sell yourself short.. you're a legend in my book

Thanks CodeWarrior ! Glad to help. Keep at it with C# I feel that it is much easier to get stuff done than VB.NET (after the learning curve going from VB to C#).

Below is the working solution to detect when PC-DMIS detects being connected to the CMM during the startup process. Many thanks to Kp61dude!

private void PCDMIS_Startup(object sender, StartupEventArgs e)
{
LoadScreen loadScreen = new LoadScreen();
loadScreen.Show();
bool startCondition = true;

Process[] pcdStartupCheck = Process.GetProcessesByName("PCDLRN");
if (pcdStartupCheck.Length > 0)
{
startCondition = false;
}
else
{
Type PCDRLN_Application = null;
object PCDObj = null;
PCDLRN.Application PCDApp = null;

try
{
PCDRLN_Application = Type.GetTypeFromProgID("PCDLRN.Application");
PCDObj = Activator.CreateInstance(PCDRLN_Application);
}
catch (System.Exception em)
{
MessageBox.Show(em.Message);
}

PCDApp = new PCDLRN.Application();
PCDApp.OperatorMode = true;
PCDApp.Visible = false;

PCDApp.ApplicationEvents.OnMachineConnected += new IApplicationEvents_OnMachineConnectedEventHandler( onMachineConnect);

void onMachineConnect(Machine machine)
{
//MessageBox.Show("machine connected");
startCondition = false;
}

if(startCondition)
{
WindowSearcher homeWindowSearch = new WindowSearcher();
homeWindowSearch.BeginWindowLook_Home();
} 
}
new MainWindow().Show();
loadScreen.Close();
 }
