Assembly reference

Posted: Jun 25, 2003 3:38 PM

Hi,

I am just picking up C# and I need a control that allows a
user to select a specific directory (not a file, just the
directory). I can't seem to find such a control already
in place.

Now, I did find a DriveListBox and a DirListBox control They're not really what I want, but i was making do with them when I noticed that they are defined in the code as:

private Microsoft.VisualBasic.Compatibility.VB6.DirListBox
dirListBox1;
private
Microso ft.VisualBasic.Compatibility.VB6.DriveListBox
driveListBox1;

When i run the below code, the error I am getting is
"The type or namespace name 'Compatability' does not exist in the class or namespace 'Microsoft.VisualBasic'(are you missing an assembly reference?)"

How do i add assembly reference? Can anyone assist me?

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace DirectoryPickerDialog1
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.OpenFileDialog openFileDialog1;
private System.Windows.Forms.Button button1;
private Microsoft.VisualBasic.Compatibility.VB6.DirListBox dirListBox1;
private Microsoft.VisualBasic.Compatibility.VB6.DriveListBox driveListBox1;
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.Label label1;
/// <summary>

}

Try the following code and then include the necessary bits in your code.

<code>
using System;
using System.Windows.Forms.Design;

public class MainClass
{
public static void Main(string [] arg)
{
FolderNameEditor ed = new FolderNameEditor();
string name = "";
string folderName = (string)ed.EditValue(null, name);

Console.WriteLine(folderName);
}

}
</code>

/thanks,
Nauman Leghari
