Should be simple, but I am drawing a blank. I would like to build a winform context menu off of traget folder from my system. So say I have folder [C:\something\] and within it there is the following:
C:\something\subfolder\
C:\something\subfolder\something1.txt
C:\something\subfolder\something3.txt
C:\something\subfolder\subfolder2\xxx.txt
C:\something\123.txt

I like to build the context menu to mimic the above showing just the file names or folder names. whenever it hits a sub folder i need a new node on the menu with more sub items.

Any ideas?

VB 2K5 or C# - either would be fine.

thanks in advance.

Here is a simple example...
Public Class Form1
 
    Private WithEvents cms As New ContextMenuStrip
    Private MyDocumentsSubFolder As String = "ContextMenuTest"
    Private SourceFolder As String = System.IO.Path.Combine(My.Computer.FileSystem.SpecialDirectories.MyDocuments, MyDocumentsSubFolder)
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.ContextMenuStrip = cms
    End Sub
 
    Private Sub cms_Opening(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles cms.Opening
        cms.Items.Clear()
        BuildMenu(New System.IO.DirectoryInfo(SourceFolder))
        e.Cancel = False ' <-- YES...this was necessary!  Without it, the menu would not appear on the FIRST Right Click.
    End Sub
 
    Private Sub BuildMenu(ByVal di As System.IO.DirectoryInfo, Optional ByVal tsmi As ToolStripMenuItem = Nothing)
        Try
            For Each fi As System.IO.FileInfo In di.GetFiles
                Dim mi As New ToolStripMenuItem(fi.Name)
                mi.Tag = fi.FullName
                AddHandler mi.Click, AddressOf tsmi_Click
                If IsNothing(tsmi) Then
                    cms.Items.Add(mi)
                Else
                    tsmi.DropDownItems.Add(mi)
                End If
                Application.DoEvents()
            Next
        Catch ex As Exception
        End Try
 
        Try
            For Each subDi As System.IO.DirectoryInfo In di.GetDirectories
                Dim mi As New ToolStripMenuItem(subDi.Name)
                If IsNothing(tsmi) Then
                    cms.Items.Add(mi)
                Else
                    tsmi.DropDownItems.Add(mi)
                End If
                BuildMenu(subDi, mi)
                Application.DoEvents()
            Next
        Catch ex As Exception
        End Try
    End Sub
 
    Private Sub tsmi_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim tsmi As ToolStripMenuItem = DirectCast(sender, ToolStripMenuItem)
        If Not IsNothing(tsmi.Tag) AndAlso TypeOf tsmi.Tag Is String Then
            Process.Start(tsmi.Tag)
        End If
    End Sub
 
End Class
