View Full Version : GeoCoding in Word via UserForm

Hello All,

I have a UserForm that populates data and replaces all Bookmarks and References with what the user inputs. I would love to take the address from the input box and use it to find the Lat and Log coords and populate that in a bookmark made on the Word Document.

I have found someones GeoCoding code in Excel and it outputs to the cell to the right of where the address is entered.

How can I assign this value to a bookmark on my document?

Any help is much appreciated.

The code I found is as follows:





Option Explicit


Function GetCoordinates(Address As String) As String

'-----------------------------------------------------------------------------------------------------
'This function returns the latitude and longitude of a given address using the Google Geocoding API.
'The function uses the "simplest" form of Google Geocoding API (sending only the address parameter),
'so, optional parameters such as bounds, key, language, region and components are NOT used.
'In case of multiple results (for example two cities sharing the same name), the function
'returns the FIRST OCCURRENCE, so be careful in the input address (tip: use the city name and the
'postal code if they are available).

'NOTE: As Google points out, the use of the Google Geocoding API is subject to a limit of 2500
'requests per day, so be careful not to exceed this limit.

'In order to use this function you must enable the XML, v3.0 library from VBA editor:
'Go to Tools -> References -> check the Microsoft XML, v3.0.

Dim Request As New XMLHTTP30
Dim Results As New DOMDocument30
Dim StatusNode As IXMLDOMNode
Dim LatitudeNode As IXMLDOMNode
Dim LongitudeNode As IXMLDOMNode

'Get the status node value.

'Based on the status node result, proceed accordingly.
Select Case UCase(StatusNode.Text)

Case "OK" 'The API request was successful. At least one geocode was returned.

'Get the latitdue and longitude node values of the first geocode.
Set LatitudeNode = Results.SelectSingleNode("//result/geometry/location/lat")
Set LongitudeNode = Results.SelectSingleNode("//result/geometry/location/lng")

'Return the coordinates as string (latitude, longitude).
GetCoordinates = LatitudeNode.Text & ", " & LongitudeNode.Text

Case "ZERO_RESULTS" 'The geocode was successful but returned no results.
GetCoordinates = "The address probably not exists"

Case "OVER_QUERY_LIMIT" 'The requestor has exceeded the limit of 2500 request/day.

GetCoordinates = "Request was empty or malformed"

Case "UNKNOWN_ERROR" 'Indicates that the request could not be processed due to a server error.
GetCoordinates = "Unknown error"

Case Else 'Just in case...
GetCoordinates = "Error"

End Select

'In case of error, release the objects.
errorHandler:
Set StatusNode = Nothing
Set LatitudeNode = Nothing
Set LongitudeNode = Nothing
Set Results = Nothing
Set Request = Nothing

End Function


'--------------------------------------------------------------------------
'The next two functions using the GetCoordinates function in order to get
'the latitude and the longitude correspondingly of a given address.
'--------------------------------------------------------------------------


Function GetLatidue(Address As String) As Double


Dim Coordinates As String

'Get the coordinates for the given address.
Coordinates = GetCoordinates(Address)

'Return the latitude as number (double).
If Coordinates <> "" Then
GetLatidue = CDbl(Left(Coordinates, WorksheetFunction.Find(",", Coordinates) - 1))
End If


End Function


Function GetLongitude(Address As String) As Double


Dim Coordinates As String

'Get the coordinates for the given address.
Coordinates = GetCoordinates(Address)

'Return the longitude as number (double).

GetLongitude = CDbl(Right(Coordinates, Len(Coordinates) - WorksheetFunction.Find(",", Coordinates)))

My Userform code (as a snippit) is as follows:




'Location Address
Dim locationAddress As Range
Set locationAddress = ActiveDocument.Bookmarks("Address").Range
locationAddress.Text = Me.TextBox4.Value
ActiveDocument.Bookmarks.Add "Address", locationAddress

Document needs a bookmark named Lat and a bookmark names Long

Userform Code (form needs a textbox for entering address and a command button.


Option Explicit
Private Sub CommandButton1_Click()
Dim Data As GoogleMapCoordinates
Dim oRng As Word.Range
Data = fcnGoogleMapQuerry(TextBox1)
If Data.Valid Then
With ActiveDocument
Set oRng = .Bookmarks("Lat").Range
oRng.Text = Data.Lat
.Bookmarks.Add "Lat", oRng
Set oRng = .Bookmarks("Long").Range
oRng.Text = Data.Longitude
.Bookmarks.Add "Long", oRng
End With
End If
Hide
lbl_Exit:
Exit Sub
End Sub

Standard Module Code:


Option Explicit
Public Type GoogleMapCoordinates
Valid As Boolean
ErrorDesc As String

Longitude As String

Sub CallForm()
