Common Dialog...

[FrancisC]

I am trying to give the ability to the users to locate a directory to be used by my application.

Using the CommonDialog control, I seem to be forced to choose a file. What I need to do is specify a directory...

Anyone knows how to do this ?

Thanks !

This will allow the user to select a folder.

End Type

Public Function BrowseForFolder(hwndOwner As Long, sPrompt As String) As String
     
    'declare variables to be used
     Dim iNull As Integer

     Dim udtBI As BrowseInfo

    'initialise variables
     With udtBI
        .hwndOwner = hwndOwner
        .lpszTitle = lstrcat(sPrompt, "")
        .ulFlags = BIF_RETURNONLYFSDIRS
     End With

    'Call the browse for folder API
     lpIDList = SHBrowseForFolder(udtBI)
     
    'get the resulting string path
     If lpIDList Then
        sPath = String$(MAX_PATH, 0)
        lResult = SHGetPathFromIDList(lpIDList, sPath)
        Call CoTaskMemFree(lpIDList)
        iNull = InStr(sPath, vbNullChar)
        If iNull Then sPath = Left$(sPath, iNull - 1)
     End If

    'If cancel was pressed, sPath = ""
     BrowseForFolder = sPath

End Function

Private Sub Command1_Click() 
Dim strResFolder As String 
strResFolder = BrowseForFolder(hWnd, "Please select a folder.") 
If strResFolder = "" Then 
Call MsgBox("The Cancel button was pressed.", vbExclamation) 
Else 
Call MsgBox("The folder " & strResFolder & " was selected.", vbExclamation) 
End If 
End Sub

You can use a DirListBox instead.
