Search Application won't search?

My search application isn't working. When the "Search" window pops up, the label stays frozen on "C:\". The application isn't freezing, just the search. Why? I can still use the buttons on it, and everything else seems to work fine.

Please help!

Like many people, I am not a big fan of downloading entire projects unnecessarily. I'm fairly sure that you could just post the code for the method in question directly, at least as a first attempt.

Also, I'm not sure that you have but just make sure you haven't included any binary files in that attachment as it's against forum rules. Always delete the bin and obj folders before zipping projects.

Fine. By the way, I haven't included the CMessageBox class. It's just a messagebox with fancy graphics.

Form1 (main form):

vb.net Code:

Public Class Form1
 
    Private Sub txtSearch_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtSearch.GotFocus
        If Me.txtSearch.Text = "Type your search here" Then
            Me.txtSearch.ForeColor = Color.White
            Me.txtSearch.Text = ""
        End If
    End Sub
 
    Private Sub txtSearch_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtSearch.LostFocus
        If Me.txtSearch.Text = "" Then
            Me.txtSearch.ForeColor = Color.Gray
            Me.txtSearch.Text = "Type your search here"
        End If
    End Sub
 
    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.X And e.Alt Then Me.Close()
    End Sub
 
    Private Sub Form1_MouseLeave(ByVal sender As Object, ByVal e As EventArgs) Handles Me.MouseLeave
        Dim cpos As New Point(Me.Location.X + Windows.Forms.Cursor.Position.X, Me.Location.Y + Windows.Forms.Cursor.Position.Y)
        Dim rect As New Rectangle(Me.Location, Me.Size)
        If Not rect.Contains(cpos) Then Me.Opacity = 0.75
    End Sub
 
    Private Sub Any_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs)
        Me.Opacity = 1.0#
    End Sub
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As Integer = 0
        AddHandler Me.MouseHover, AddressOf Any_MouseHover
        While i < Me.Controls.Count
            AddHandler Me.Controls(i).MouseHover, AddressOf Any_MouseHover
            i += 1
        End While
    End Sub
 
    Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
        If Me.txtSearch.Text = "" Or Me.txtSearch.ForeColor = Color.Gray Then
            Dim f As New CMessageBox("You must enter search terms!", "Search", SystemIcons.Exclamation)
            f.ShowDialog()
        Else
            Dim f As New Searcher(Me.txtSearch.Text)
            Me.Hide()
            f.Owner = Me
            f.Show()
            f.Search()
            Me.Show()
            'AddHandler f.FormClosed, AddressOf ShowSelf
        End If
    End Sub
    Private Sub ShowSelf(ByVal sender As Object, ByVal e As FormClosedEventArgs)
        Me.Show()
    End Sub
End Class

and Searcher (the searching form):

vb.net Code:

Public Class Searcher
    Dim _searchdir As String = "C:\"
    Dim _searchterm As String = ""
    Structure ResultInfo
        Dim FileName As String
        Dim ParentDirectory As String
    End Structure
    Dim t As System.Threading.Thread
    Delegate Sub NoArgsD()
    Delegate Sub AddResultDef(ByVal arg As ResultInfo)
    Delegate Sub SetTextDef(ByVal text As String)
    Dim doaddresult As AddResultDef = New AddResultDef(AddressOf AddResult)
    Dim dosetsttext As SetTextDef = New SetTextDef(AddressOf SetStatusText)
    Dim dofinished As NoArgsD = New NoArgsD(AddressOf Finished)
    Public Sub New(ByVal searchdir As String)
 
        ' This call is required by the Windows Form Designer.
        InitializeComponent()
 
        ' Add any initialization after the InitializeComponent() call.
        _searchdir = searchdir
    End Sub
    Private Sub Finished()
        Me.lblCurrentSearch.Text = "Done."
        Me.btnStopSearch.Visible = False
        Dim f As New CMessageBox("Search complete.", "Search", SystemIcons.Information)
        t = Nothing
    End Sub
    Public Sub Search()
        t = New Threading.Thread(AddressOf InitSearch)
        t.Start()
    End Sub
    Private Sub InitSearch()
        On Error GoTo sub_exit
        DoSearch(_searchdir)
        Me.Invoke(dofinished)
sub_exit:
    End Sub
    Private Sub DoSearch(ByVal dir As String)
        Dim di, cdi As System.IO.DirectoryInfo
        Dim fi As System.IO.FileInfo
        cdi = New IO.DirectoryInfo(dir)
        If cdi.Name.Contains(_searchterm) Then
            Dim rs As ResultInfo
            rs.FileName = cdi.Name
            If Not cdi.Parent Is Nothing Then
                rs.ParentDirectory = cdi.Parent.FullName
            Else
                rs.ParentDirectory = "My Computer"
            End If
        End If
        For Each fi In cdi.GetFiles()
            If fi.Name.Contains(_searchterm) Then
                Dim ri As ResultInfo
                ri.FileName = fi.Name
                ri.ParentDirectory = cdi.FullName
                Me.Invoke(doaddresult, ri)
            End If
        Next
        For Each di In cdi.GetDirectories()
            Me.Invoke(dosetsttext, "Currently Searching " & di.FullName)
            DoSearch(di.FullName)
        Next
    End Sub
    Private Sub AddResult(ByVal result As ResultInfo)
        Dim lvi As New ListViewItem(New String() {result.FileName, result.ParentDirectory})
        Me.lstSearchResults.Items.Add(lvi)
        lvi = Nothing
    End Sub
    Private Sub SetStatusText(ByVal str As String)
        Me.lblCurrentSearch.Text = str
    End Sub
 
    Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
        If Not t Is Nothing Then
            t.Abort()
        End If
        Me.Close()
    End Sub
 
    Private Sub btnStopSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStopSearch.Click
        t.Abort()
        Me.btnStopSearch.Visible = False
        Me.lblCurrentSearch.Text = "Search stopped."
    End Sub
End Class

Or could it just be slow? Google Desktop is indexing my files right now...
Still, I waited a while for the "current directory" label to change, but nothing happened...

Ok, not google desktop. I turned it off and waited a really long time, the label doesn't even change...

What's going wrong? Also, the form behind it seems frozen. It won't hide. Also, if this is important, ShowInTaskbar is set to False on #1 and True on #2.

I have no idea what's happening! Please help!
