[HELP] Searching Files

I try this:

Code:

Dim files As ReadOnlyCollection(Of String) files = My.Computer.FileSystem.FindInFiles("C:\", TextBox1.Text, False, FileIO.SearchOption.SearchAllSubDirectories, "*.txt") For Each FilexD As String In files ListBox1.Items.Add(FilexD) Next

But the problem is , In C:\ have some denied directories (Open as admin do not work), HOw can i make it ignore it, if is not allowed ? ( Or something)

Thanks.

On Error Resume Next?

Not that easy, If you suggest something, Test it first then show me how. Please.

Code:

Doesn't work I'm pretty sure, since your 'for' statement is the first thing to try and access the file.

Want proof? Try running just this statement.

[highlight=vb.net]
FileIO.FileSystem.GetFiles("C:\", FileIO.SearchOption.SearchAllSubDirectories)
[/highlight]

Why not list every file, then remove the ones not containing the string? Seems like an easy temporary workaround.

-.- , It dont even can add the denied directories, Thats my problem.
If possible i add them all, But i cant.

HERE, use this. Works for me.

Add this to a CLASS file

Code:

Option Strict On
Option Explicit On

Imports System.IO

Public Class FileSearch

    Private Const DefaultFileMask As String = "*.*"
    Private Const DefaultDirectoryMask As String = "*"

#Region " Member Variables "

    Private _InitialDirectory As DirectoryInfo
    Private _DirectoryMask As String
    Private _FileMask As String

    '
    Private _Directories As New ArrayList
    Private _Files As New ArrayList

#End Region

#Region " Properites "

    Public Property InitialDirectory() As DirectoryInfo
        Get
            Return _InitialDirectory
        End Get
        Set(ByVal Value As DirectoryInfo)
            _InitialDirectory = Value
        End Set
    End Property
    Public Property DirectoryMask() As String
        Get
            Return _DirectoryMask
        End Get
        Set(ByVal Value As String)
            _DirectoryMask = Value
        End Set
    End Property
    Public Property FileMask() As String
        Get
            Return _FileMask
        End Get
        Set(ByVal Value As String)
            _FileMask = Value
        End Set
    End Property

    Public ReadOnly Property Directories() As ArrayList
        Get
            Return _Directories
        End Get
    End Property
    Public ReadOnly Property Files() As ArrayList
        Get
            Return _Files
        End Get
    End Property



#End Region

#Region " Constructors "

    Public Sub New()

    End Sub

    Public Sub New( _
        ByVal BaseDirectory As String, _
        Optional ByVal FileMask As String = DefaultFileMask, _
        Optional ByVal DirectoryMask As String = DefaultDirectoryMask)

        Me.New(New IO.DirectoryInfo(BaseDirectory), FileMask, DirectoryMask)

    End Sub

    Public Sub New( _
        ByVal BaseDirectory As DirectoryInfo, _
        Optional ByVal FileMask As String = DefaultFileMask, _
        Optional ByVal DirectoryMask As String = DefaultDirectoryMask)

        _InitialDirectory = BaseDirectory
        _FileMask = FileMask
        _DirectoryMask = DirectoryMask

    End Sub

#End Region

    Protected Overrides Sub Finalize()
        _Files = Nothing
        _Directories = Nothing
        MyBase.Finalize()
    End Sub


    Public Sub Search( _
        Optional ByVal BaseDirectory As DirectoryInfo = Nothing, _
        Optional ByVal FileMask As String = Nothing, _
        Optional ByVal DirectoryMask As String = Nothing)

        If Not IsNothing(BaseDirectory) Then
            _InitialDirectory = BaseDirectory
        End If

        If IsNothing(_InitialDirectory) Then
            Throw New ArgumentException("A Directory Must be specified!", "Directory")
        End If

        If IsNothing(FileMask) Then
            _FileMask = DefaultFileMask
        Else
            _FileMask = FileMask
        End If


        If IsNothing(DirectoryMask) Then
            _DirectoryMask = DefaultDirectoryMask
        Else
            _DirectoryMask = DirectoryMask
        End If

        DoSearch(_InitialDirectory)
    End Sub

    Private Sub DoSearch(ByVal BaseDirectory As DirectoryInfo)

        Try
            _Files.AddRange(BaseDirectory.GetFiles(_FileMask))
        Catch u As UnauthorizedAccessException
            'Siliently Ignore this error, there isnt any simple
            'way to avoid this error.

        End Try

        Try
            Dim Directories() As DirectoryInfo = BaseDirectory.GetDirectories(_DirectoryMask)
            _Directories.AddRange(Directories)

            For Each di As DirectoryInfo In Directories
                DoSearch(di)
            Next

        Catch u As UnauthorizedAccessException
            'Siliently Ignore this error, there isnt any simple
            'way to avoid this error.

        End Try

    End Sub

End Class

To use it:

Code:

 Dim x As New FileSearch(New IO.DirectoryInfo("c:\Screenshots[imageUP]"), "*.png")

        *****arch()

        

        For Each imageFiles As FileInfo In x.Files

            Dim img = Image.FromFile(imageFiles.FullName)

            ListBox1.Items.Add(imageFiles.FullName)


            img = Nothing
        Next

Works for Subdirectories!

Multithreading is recommended in this case,

Can you say me what is the ParamArray ? @Blubb1337

EDIT: Not worked, "Access to the path 'C:\Documents and Settings\' is denied."

ParamArray means to allow a subrotine to take a variable no. of arguments.

You can just use "*.*" as last parameter.

Start the program as admin + try to change the exception type depending on the exception you get.

The error is not in Files.Add , Its before the Try thing ..

@³²³ Still giving me error.

Code:

Dim files As String()
        files = IO.Directory.GetFiles("C:\", "*.exe", IO.SearchOption.AllDirectories)
        For Each File As String In files
           Listbox1.Items.Add(File)
        Next

I just realized I have been using this code in my current project. -.-

Hmm, AllDirectories is glitchy (atleast searching for all .exe files in Windows folder). however Toplevelonly works instantly..

AllDirectories works with a limited no of files.

What error

Ah I see. Did you try the link in my earlier post?
