How do I create a folder in VB if it doesn't exist? - vb.net

Question

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.

Answer 1

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

Answer 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.

Answer 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

Answer 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

Answer 5

Try this: Directory.Exists(TheFolderName) and Directory.CreateDirectory(TheFolderName)
(You may need: Imports System.IO)

Answer 6

VB.NET? System.IO.Directory.Exists(string path)

Answer 7

Directory.CreateDirectory() should do it.
http://msdn.microsoft.com/en-us/library/system.io.directory.createdirectory(VS.71).aspx
Also, in Vista, you probably cannot write into C: directly unless you run it as an admin, so you might just want to bypass that and create the dir you want in a sub-dir of C: (which i'd say is a good practice to be followed anyways. -- its unbelievable how many people just dump crap onto C:
Hope that helps.

Answer 8

(imports System.IO)
if Not Directory.Exists(Path) then
Directory.CreateDirectory(Path)
end if

Answer 9

If Not Directory.Exists(somePath) then
Directory.CreateDirectory(somePath)
End If

Answer 10

You should try using the File System Object or FSO. There are many methods belonging to this object that check if folders exist as well as creating new folders.

Answer 11

I see how this would work, what would be the process to create a dialog box that allows the user name the folder and place it where you want to.
Cheers

Answer 12

Just do this:
Dim sPath As String = "Folder path here"
If (My.Computer.FileSystem.DirectoryExists(sPath) = False) Then
My.Computer.FileSystem.CreateDirectory(sPath + "/<Folder name>")
Else
'Something else happens, because the folder exists
End If
I declared the folder path as a String (sPath) so that way if you do use it multiple times it can be changed easily but also it can be changed through the program itself.
Hope it helps!
