[RESOLVED] Delete file in subfolder

Hello all,

I have a problem and can't figure it out anymore.
Bin looking at this prob for like a day now.

I hope any of you can and want to help me.

I have below code and i want to change it so that it will delete the file "test.test" in a sub directory.
I don't know the name of the sub directory so it has to go true the sub directories and when it finds the "test.test" file
it needs to delete it.

The folder only has 2 sub directories. That is the only thing i know.

Code:

---

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

            Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) & "\test\"
           
            If System.IO.Directory.Exists(path) = True Then
                System.IO.Directory.Delete(path, True)
            Else
                msgbox("file isn't there")
            End If

    End Sub

---

This code will work for you

Ok i found this code at the link you gave me.

This function is pretty new for me.

Do i put this in a class?

Can you explain/help me how to use this ?

Code:

---

Imports System
Imports System.IO

Public Class MainClass

  Shared Sub Main()

    Dim nameOfDirectory As String = "C:\"
    Dim myDirectory As DirectoryInfo
    myDirectory = New DirectoryInfo(nameOfDirectory)
    WorkWithDirectory(myDirectory)

  End Sub

  Shared Public Sub WorkWithDirectory(ByVal aDir As DirectoryInfo)
    Dim nextDir As DirectoryInfo
    WorkWithFilesInDir(aDir)
    For Each nextDir In aDir.GetDirectories
      WorkWithDirectory(nextDir)
    Next
  End Sub

  Shared Public Sub WorkWithFilesInDir(ByVal aDir As DirectoryInfo)
    Dim aFile As FileInfo
    For Each aFile In aDir.GetFiles()
      Console.WriteLine(aFile.FullName)
    Next
  End Sub

 
End Class

---

Form with a single button

Code:

---

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        RemoveFile("D:\Data", "test.test")
    End Sub
End Class

---

Code Module, replace the console write with your delete method

Code:

---

Imports System.IO
Module FileCode
    Private FileToRemove As String = ""
    Public Sub RemoveFile(ByVal FolderName As String, ByVal FileName As String)
        FileToRemove = FileName
        RecurseDirectory(New DirectoryInfo(FolderName))
    End Sub
    Public Sub RecurseDirectory(ByVal FolderInfo As DirectoryInfo)
        Dim nextDir As DirectoryInfo
        WorkFiles(FolderInfo)
        For Each nextDir In FolderInfo.GetDirectories
            RecurseDirectory(nextDir)
        Next
    End Sub
    Public Sub WorkFiles(ByVal FolderInfo As DirectoryInfo)
        Dim FI As FileInfo
        For Each FI In FolderInfo.GetFiles()

            If IO.Path.GetFileName(FI.FullName.ToLower) = FileToRemove.ToLower Then
                Console.WriteLine(FI.FullName)
            End If
        Next
    End Sub
End Module

Alright thanks men.

Works like a charm.

I changed console.writeline with:

Code:

---

File.Delete(FI.FullName)

---

It's a normal file and can be deleted at any time.

And changed the single button click to:

Code:

---

Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
        RemoveFile(path & "\test\test\", "test.test")

---

Thanks allot for the fast reply and the fast help.

You rock

Good to hear this works for you.

For the path you can also use Io.Path.Combine

Code:

---

Dim path As String = IO.Path.Combine( _
    Environment.GetFolderPath( _
        Environment.SpecialFolder.ApplicationData), "test\test\")

---

That's an even better option.
I can use that in the rest of my code.

Thanks again Keven.
