How to fix the errors

Question

Dear All,

Grateful if anybody tells me how to fix the errors in the attached figure.

TIA

Answer 1

Seems your project has issues overall that defy what a standard WinForm project should have.

The only thing I see different between my and your project is the .NET Framework version yet that should not make using static System.Configuration.ConfigurationManager; not to be found.

So I created a mirror image of the project found here that uses System.Configuration.ConfigurationManager version 5 rather than version 4. I'm going to guess even though this should work it will not as the first version should have worked so try if you want and let me know what happens.

Answer 2

Did you follow the instructions here?

http://objectlistview.sourceforge.net/cs/gettingStarted.html

"Download the ObjectListView project

Add the ObjectListView project to your project (right click
on your solution; choose “Add...”, “Existing Project”, then
choose the ObjectListView.csproj)

In your project, add a reference to the ObjectListView project
(right click on your project; choose “Add Reference...”, choose
“Projects” tab; then double click on the ObjectListView project)

Build your project"

Answer 3

Add at beginning :

using BrightIdeasSoftware;

Answer 4

As @WayneAKing mentioned and @Castorix31 you need the using statement as seen in this code sample in MainForm.cs, line 19. And note the project reference.

Answer 5

Try the following project

• Uses .NET Framework 4.8
• Nuget package
• Also added one instance of the component via the IDE toobox.

Form code

using System;
using System.Windows.Forms;
using `BrightIdeasSoftware;`

namespace ObjectListViewFramework
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            var objectListViewLocal = new ObjectListView();
        }
    }
}
