Check if a directory exist and create a directory (1 Viewer)

[raindrop3]

Hello,

How can I check if a directory exist? I.e: I have a directory c:\database\photos\0. I want to check if this directory exist and then create a directory, called c:\database\photos\1.

Can VBA create a directory?

Thanks in advantage for helping me. It's becoming a serious problem for me.

To find out if a directory exists:

If Dir(strDirectoryPath)<>"" Then
True
Else: False
End if

To create a directory:

MkDir strDirectoryPath

Therefore this should do what you want:

Public Sub CheckDir(strDirectoryPath As String)

If Dir(strDirectoryPath)<>"" Then
MkDir strDirectoryPath
End if

End Sub

Damn, not quite right. I'll try again:

Public Sub CheckDir(strDirectoryPath As String)

If Dir(strDirectoryPath)="" Then
MkDir strDirectoryPath
End if

End Sub

Thanks, ed. You pointed me on the right direction. I hope i can figure it out myself now!

Thanks again.

 

[hutmannetje]

are you sure about that to use this, why don't you use c++??
see you later.

 

[raindrop3]

I can't use c because the application i'am workin at, is completely access-based...

And seems as this is an Access/VBA forum I thought the answer would answer itself really!

FYI

If Dir(strDirectoryPath)="" then MkDir strDirectoryPath
Did not work properly for me in Access 2007, even if the directory existed, it still returned ""

However,
If Dir(strDirectoryPath,vbDirectory)="" then MkDir strDirectoryPath
worked properly.

If you had searched the forum then you would have a found a few threads like http://www.access-programmers.co.uk/forums/showthread.php?t=27578&highlight=MkDir with the anwer.

This does not work for me!!!!
I'm using access 2003 (That is office computer no control on it)
I added this simple piece of code:

If dir("C:\Text Files", vbDirectory) <> "" Then
  MsgBox "dir worked"
End If

No matter this path exist or not this code results in an error and says "Compile Error: Expected Function or variable"

what is wrong?

 

[mane_uk]

you can try something like:

intPath = Len(Dir(strDirectoryPath,vbDirectory))
If intPath = 0 Then
   MkDir strDirectoryPath
End if

Cheers

This is compiler error, not run-time, it does not makes any difference where you put it?

 

[JANR]

It depends on where and how the whole code looks like

This in a Standard Module:

Function foo()
If Dir("d:\temp", vbDirectory) <> "" Then
    MsgBox "dir worked"
End If
End Function

Works.

It seems that it is not recognising your DIR function... 2 things come up to mind:
* Missing reference; or
* SandBox mode

Have a look to this link http://beckelman.net/post/2008/01/06/MS-Access-Undefined-function-Dir-in-query-expression.aspx)

Hope it helps

It works fine, but you can just add one level with this command.
So if you want to add two level (sub directorie) then you have to execute mkdir two times.

Success

This function works for me :-

Public Function CheckDir(strDirectoryPath As String) As Boolean
Dim IsDir As Boolean
If Len(Dir(strDirectoryPath, vbDirectory)) = 0 Then
IsDir = False
Else
IsDir = True
End If
CheckDir = IsDir
End Function
