Hello,
I know it may be silly to ask this
but I m stuck with this: so please help
I have two classes in the same namespace
Now, what I want to do is on Form_Load Event I want to call all the functions present in the Setting_Layer_Path class
One way of doing is by creating object of the Setting_Layer_Path Class and working with the functions within it
Can someone tell me, is there any other way of calling the functions directly without creating object
Attach is the codes
Setting_Layer_Path Class
Form frmDT_selection.cs
Any help would be deeply appreciated
Thanks in advance

1. Setting_Layers_Path class files
Which helps in establishing connection to the layers(GIS connections). It contains number of functions which return an object of specific datatype
2. Form Class
One way of doing is by creating object of the Setting_Layer_Path Class and working with the functions within it
Can someone tell me, is there any other way of calling the functions directly without creating object
Attach is the codes
Setting_Layer_Path Class
C# Syntax (Toggle Plain Text)
namespace RELGIS_DT_Load_Calculation { public sealed class Setting_Layers_Path { #region User Defined Variables IMxDocument pMxDoc; IMap pMap; #endregion public Setting_Layers_Path() { } private static IFeatureLayer get_DivsionFeatureLayer() { return null; } private static IFeatureLayer get_SubDivisionFeatureLayer() { } private static IFeatureLayer get_EHVStnFeatureLayer() { } private static IFeatureLayer get_SubStnFeatureLayer() { return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "AU_SUBSTATION"); } private static IFeatureLayer get_DistributedTransformerFeatureLayer() { return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "DISTRIBUTIONTRANSFORMER"); } } }
Form frmDT_selection.cs
namespace RELGIS_DT_Load_Calculation
{
public partial class frmDT_selection : Form
{
#region variable declaration
IMxDocument pMxDoc;
#endregion
public frmDT_selection(IApplication m_app)
{
InitializeComponent();
}
private void frmDT_selection_Load(object sender, EventArgs e)
{
//This is where i want to call the functions of the Setting_Layers_Path class without creating an object
}Any help would be deeply appreciated
Thanks in advance

this is claa example
[/code=c#]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace DaniWebtest3
{
class time
{
public static void GetIt()
{
MessageBox.Show(DateTime.Now.ToString());
}
}
}
[/code]
so u must declar ur methode public static this means that only the class will acceses this function and u will not create instance for ur class .
read this :

Make the methods as Public Static.Then you can call the methods using the classname itself without creating obect.
namespace RELGIS_DT_Load_Calculation
{
public sealed class Setting_Layers_Path
{
#region User Defined Variables
IMxDocument pMxDoc;
IMap pMap;
#endregion
public Setting_Layers_Path()
{
}
public static IFeatureLayer get_DivsionFeatureLayer()
{
return null;
}
public static IFeatureLayer get_SubDivisionFeatureLayer()
{
}
public static IFeatureLayer get_EHVStnFeatureLayer()
{
}
public static IFeatureLayer get_SubStnFeatureLayer()
{
return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "AU_SUBSTATION");
}
public static IFeatureLayer get_DistributedTransformerFeatureLayer()
{
return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "DISTRIBUTIONTRANSFORMER");
}
}
}
namespace RELGIS_DT_Load_Calculation
{
public sealed class Setting_Layers_Path
{
#region User Defined Variables
IMxDocument pMxDoc;
IMap pMap;
#endregion
public Setting_Layers_Path()
{
}
public static IFeatureLayer get_DivsionFeatureLayer()
{
return null;
}
public static IFeatureLayer get_SubDivisionFeatureLayer()
{
}
public static IFeatureLayer get_EHVStnFeatureLayer()
{
}
public static IFeatureLayer get_SubStnFeatureLayer()
{
return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "AU_SUBSTATION");
}
public static IFeatureLayer get_DistributedTransformerFeatureLayer()
{
return CommonGISFunc.FirstFeatureLayerWithMN(pMap, "DISTRIBUTIONTRANSFORMER");
}
}
}
