Thread: Return object with properties

Return object with properties Your last visit to this thread was on 1/1/1970 12:00:00 AM

I have a .Net Extension wrapper DLL that calls a native .Net DLL. What I would like to do is have the DLL return an object (or class) with multiple properties. When I return the object/class it returns empty but if I return a property it sends it back to the DLL without issue. Is there a way that I can return the object instead of returning each individual property?

This works:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.OleDb;
using System.Windows.Forms;
using Sage.SalesLogix.NetExtensions;
using TimeLinx;

namespace TimeLinxLAN
{
public class Class1 : Sage.SalesLogix.NetExtensions.BaseRunnable
{
public override object Run(object[] args)
{
OleDbConnection _conn = new OleDbConnection(SlxApplication.ConnectionString);
_conn.Open();
TimeLinx_Settings tlxSettings = TimeLinx_Settings.GetTimeLinx_Settings(_conn);

return tlxSettings.StartDay.ToString();

}
}
}

This returns an empty resultset

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.OleDb;
using System.Windows.Forms;
using Sage.SalesLogix.NetExtensions;
using TimeLinx;

namespace TimeLinxLAN
{
public class Class1 : Sage.SalesLogix.NetExtensions.BaseRunnable
{
public override object Run(object[] args)
{
OleDbConnection _conn = new OleDbConnection(SlxApplication.ConnectionString);
_conn.Open();
TimeLinx_Settings tlxSettings = TimeLinx_Settings.GetTimeLinx_Settings(_conn);

return tlxSettings;

}
}
}

Thanks in advance.....

Ok looks like I was finally able to get the system to do what I was looking for. Ended up being more coding than I was hoping for but this works. If anybody has a better way of doing it I would love the feedback as I have alot of work ahead of me implementing this in our product.

C# code that creates a wrapper around existing DLL:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.OleDb;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using Sage.SalesLogix.NetExtensions;
using TimeLinx;

namespace TimeLinxLAN
{

[ComVisible(true)]
[Guid("F97D36EF-D10A-48bf-A58C-690201D315D4")]
public class Class1 : Sage.SalesLogix.NetExtensions.BaseRunnable
{
public String ManagerApprovalChngAllowed;
public String ProjManagerApprovalChngAllowed;
public String FinManagerApprovalChgAllowed;
public String StartDay;
public Double DefaultIncrement;
public Double DefaultMinimum;
public String DefaultTravel;
public String UniqueServiceSummaryRecords;

public override object Run(object[] args)
{
OleDbConnection _conn = new OleDbConnection(SlxApplication.ConnectionString);
_conn.Open();

//Call Original DLL
TimeLinx_Settings tlxSettings = TimeLinx_Settings.GetTimeLinx_Settings(_conn);

//Populate new Class Properties
this.ManagerApprovalChngAllowed = tlxSettings.ManagerApprovalChngAllowed;
this.ProjManagerApprovalChngAllowed = tlxSettings.ProjManagerApprovalChngAllowed;
this.FinManagerApprovalChgAllowed = tlxSettings.FinManagerApprovalChgAllowed;
this.StartDay = tlxSettings.StartDay;
this.DefaultIncrement = tlxSettings.DefaultIncrement;
this.DefaultMinimum = tlxSettings.DefaultMinimum;
this.DefaultTravel = tlxSettings.DefautlTravel;
this.UniqueServiceSummaryRecords = tlxSettings.UniqueServiceSummaryRecords;
//Return to SLX
return this;

}
}
}

This is the SLX code

Sub Button1Click(Sender)
Dim ext, x, Setting
' application.Debug.Fail
ext = Application.Managed.Create("TimeLinxLAN", "TimeLinxLAN.Class1")
Set x = Application.Managed.Run(ext, empty)
Msgbox x.StartDay
MsbBox x.MinimumIncrement
End Sub

And everything works as it should. Next effort will be seeing if I can save the object as a GlobalInfo variable and reuse it in other parts of the application.
