How do I create a folder in VB if it doesn't exist?

I wrote myself a little downloading application so that I could easily grab a set of files from my server and put them all onto a new pc with a clean install of Windows, without actually going on the net. Unfortunately I'm having problems creating the folder I want to put them in and am unsure how to go about it.

I want my program to download the apps to program files\any name here\

So basically I need a function that checks if a folder exists, and if it doesn't it creates it.

Solution 1:

If Not System.IO.Directory.Exists(YourPath) Then
    System.IO.Directory.CreateDirectory(YourPath)
End If

Solution 2:

Under System.IO, there is a class called Directory. Do the following:

If Not Directory.Exists(path) Then
    Directory.CreateDirectory(path)
End If

It will ensure that the directory is there.

Solution 3:

Try the System.IO.DirectoryInfo class.

The sample from MSDN:

Imports System
Imports System.IO

Public Class Test
    Public Shared Sub Main()
        ' Specify the directories you want to manipulate.
        Dim di As DirectoryInfo = New DirectoryInfo("c:\MyDir")
        Try
            ' Determine whether the directory exists.
            If di.Exists Then
                ' Indicate that it already exists.
                Console.WriteLine("That path exists already.")
                Return
            End If

            ' Try to create the directory.
            di.Create()
            Console.WriteLine("The directory was created successfully.")

            ' Delete the directory.
            di.Delete()
            Console.WriteLine("The directory was deleted successfully.")

        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())
        End Try
    End Sub
End Class

Solution 4:

Since the question didn't specify .NET, this should work in VBScript or VB6.

Dim objFSO, strFolder
strFolder = "C:\Temp"
Set objFSO = CreateObject("Scripting.FileSystemObject")
If Not objFSO.FolderExists(strFolder) Then
   objFSO.CreateFolder(strFolder)
End If

Solution 5:

Try this: Directory.Exists(TheFolderName) and Directory.CreateDirectory(TheFolderName)

(You may need: Imports System.IO)
