Find Your Dropbox Folder in VBA

Here’s a function to get the location of the Dropbox folder:

Public Function DropBox() As String

Dim DropboxHostFile As String
Dim DropboxHostFileNumber As Long
Dim Base64EncodedPath As String
Dim TempXMLDocument As MSXML2.DOMDocument60
Dim Base64XMLNode As MSXML2.IXMLDOMElement

DropboxHostFile = Environ("appdata") & "\Dropbox\host.db"
DropboxHostFileNumber = FreeFile

Open DropboxHostFile For Input As DropboxHostFileNumber
Base64EncodedPath = Input$(LOF(DropboxHostFileNumber), DropboxHostFileNumber)
Close DropboxHostFileNumber

Set TempXMLDocument = New MSXML2.DOMDocument60
Set Base64XMLNode = TempXMLDocument.createElement("b64")
Base64XMLNode.DataType = "bin.base64"
Base64XMLNode.Text = Split(Base64EncodedPath, vbLf)(1)

DropBox = StrConv(Base64XMLNode.nodeTypedValue, vbUnicode)

End Function

According to Reinaldo there is a host.db file in the Roaming directory that stores this information. The Environ("appdata") function returns the Roaming directory in Win7. I open host.db and read in the text. Then I create a new XML document, thanks to Tim Hastings, to write in the Base64 text and read out the byte data that is converted to Unicode. There’s two lines in my host.db file, so I split on vbLf and only use the second line.

Here’s what it would look like if I wrote this function and didn’t want to poke my eyes out afterward.

Public Function DropBox() As String

Dim sFile As String
Dim lFile As Long
Dim sPath As String
Dim xDoc As MSXML2.DOMDocument60
Dim xNode As MSXML2.IXMLDOMElement

sFile = Environ("appdata") & "\Dropbox\host.db"
lFile = FreeFile

Open sFile For Input As lFile
sPath = Input$(LOF(lFile), lFile)
Close lFile

Set xDoc = New MSXML2.DOMDocument60
Set xNode = xDoc.createElement("b64")
xNode.DataType = "bin.base64"
xNode.Text = Split(sPath, vbLf)(1)

DropBox = StrConv(xNode.nodeTypedValue, vbUnicode)

End Function

  1. another anti poking measure:

    Sub M_snb()
    With CreateObject("Msxml2.DOMDocument.6.0")
    With .createElement("b")
    .DataType = "bin.base64"
    .Text = Split(CreateObject("scripting.filesystemobject").opentextfile(Environ("appdata") & "\DropBox\host.db").readall, vbLf)(1)
    MsgBox StrConv(.nodeTypedValue, 64)
    End With
    End With
    End Sub

To create code blocks or other preformatted text, indent by four spaces:

    This will be displayed in a monospaced font. The first four 
    spaces will be stripped off, but all other whitespace

To create not a block, but an inline code span, use backticks:
