EPLAN-API: Offline Applikation starten

Mit der Offline Applikation hat man man vielen Problemen zu kämpfen, angefangen beim Start…

Ich hab auf GitHub mal Methoden bereitgestellt um das zu vereinfach.

 

Verwendung WPF

var eplanOffline = new EplanOffline();
eplanOffline.StartWpf(this);
if (!eplanOffline.IsRunning)
{
	throw new NotImplementedException();
}
eplanOffline.Close();

Verwendung Windows Forms

var eplanOffline = new EplanOffline();
eplanOffline.StartWindowsForms(this);
if (!eplanOffline.IsRunning)
{
	throw new NotImplementedException();
}
eplanOffline.Close();

 

Ich habe bewusst darauf verzichtet dass alles im Konstruktor zu machen, da sonst WindowsForms in WPF und anders herum hinzugefügt werden muss.

Hier mal der Code dazu (Starter ist zum registrieren der Lizenz/DLLs):

using System.Collections.Generic;
using System.IO;
using System.Linq;
using Eplan.EplApi.Starter;

namespace Suplanus.Sepla.Application
{
    /// <summary>
    /// EPLAN Starter Helper: No other EPLAN-Namespaces are allowd
    /// </summary>
    public class Starter
    {
        public static string GetBinPathLastVersion()
        {
            List<EplanData> eplanVersions = new List<EplanData>();

            List<EplanData> eplanVersions32Bit = new List<EplanData>();
            new EplanFinder().GetInstalledEplanVersions(ref eplanVersions32Bit);
            eplanVersions.AddRange(eplanVersions32Bit);

            List<EplanData> eplanVersions64Bit = new List<EplanData>();
            new EplanFinder().GetInstalledEplanVersions(ref eplanVersions64Bit, true);
            eplanVersions.AddRange(eplanVersions64Bit);

            eplanVersions = new List<EplanData>(eplanVersions
                .Where(obj => obj.EplanVariant.Equals("Electric P8"))
                .OrderBy(obj => obj.EplanVersion));

            EplanData eplanData = eplanVersions.LastOrDefault();

            var binPath = Path.GetDirectoryName(eplanData.EplanPath);

            AssemblyResolver resolver = new AssemblyResolver();
            resolver.SetEplanBinPath(binPath);
            resolver.PinToEplan();

            return binPath;
        }
    }
}

 

using System;
using System.Windows;
using System.Windows.Forms;
using System.Windows.Interop;
using Eplan.EplApi.System;
using Suplanus.Sepla.Gui;

namespace Suplanus.Sepla.Application
{
    public class EplanOffline
    {
        public EplApplication Application;

	    public Preview Preview;

		/// <summary>
		/// Starts EPLAN with the last version of Electric P8 and attach to (WPF) window
		/// </summary>
		/// <param name="window"></param>
		public void StartWpf(Window window)
	    {
			IntPtr handle = new WindowInteropHelper(window).Handle;
			string binPath = Starter.GetBinPathLastVersion();
			Start(handle,binPath);
		}

		/// <summary>
		/// Starts EPLAN with the last version of Electric P8 and attach to (WF) form
		/// </summary>
		/// <param name="form"></param>
		public void StartWindowsForms(Form form)
		{
			IntPtr handle = form.Handle;
			string binPath = Starter.GetBinPathLastVersion();
			Start(handle, binPath);

		public bool IsRunning
        {
            get { return Application != null; }
        }

	    

	    /// <summary>
		/// Starts the application
		/// </summary>
		/// <param name="handle"></param>
		/// <param name="binPath"></param>
        private void Start(IntPtr handle, string binPath)
        {
            if (Application == null)
            {
                try
                {
                    EplApplication eplApplication = new EplApplication();
                    eplApplication.EplanBinFolder = binPath;
                    eplApplication.ResetQuietMode();
                    eplApplication.SetMainFrame(handle);
                    eplApplication.Init("", true, true);
                    Application = eplApplication;
                }
                catch
                {
                    Application = null;
                } 
            }
        }

		/// <summary>
		/// Release all objects
		/// </summary>
        public void Close()
        {
            if (Application != null)
            {
                Application.Exit();
                Application = null;
            }
        }
    }
}

In diesem Code wird immer die aktuellste Version von EPLAN Electric P8 verwendet. Ich bau irgendwann noch Methoden zur Auswahl von der Lizenz / Version.
