Hi,

I have the code below that takes lat/longs from a file and plots them on a Google Map. The code generates a html file which automatically fires up in the web browser.

I have a couple of issues with this where I need to make amendments to the vba code and the underlying html.

Firstly I need to add a permanent label marker on each pin to show the time stamp from column C. Then when I click on a pin I need to see data relating to that marker including the information shown in column D plus possibly additional columns of data as well, however the code below seems to suggest that I can only have a 3 columns of data for this to work?

For the label marker, this works as a hard coded solution but I need to incorporate this or something similar into my macro

var marker2= new google.maps.Marker(
{
position: new google.maps.LatLng(53.593349, -2.296605),

label: {
color: 'black',
fontWeight: 'bold',
text: '14:20',
},

Full Code:

VBA Code: 
Sub GenerateMap()

    Dim c As Range
    Dim FileName As String
    Dim Label As String
    Dim Latitude As String
    Dim Longitude As String
    Dim rng As Range
    Dim ws As Worksheet

    Set ws = ThisWorkbook.Sheets("Mapping Data")
    Set rng = ws.Range("A2:C" & ws.Cells(Rows.Count, "A").End(xlUp).Row)
    
    If rng.Columns.Count < 2 Then
        MsgBox "You need to have at least 2 columns;(1) the latitude and (2) the longitude.", vbCritical + vbOKOnly
        Exit Sub
    End If
   
    If rng.Columns.Count > 3 Then
        MsgBox "You can't highlight more than 3 columns; (1) the latitude, (2) the longitude, and (3) a label.", vbCritical + vbOKOnly
        Exit Sub
    End If
   
    FileName = Environ("Temp") & "\Google Maps.html"
    
    Latitude = Trim(rng.Cells(1, 1).Text)
    Longitude = Trim(rng.Cells(1, 2).Text)

That looks great thanks. Only problem is I know very little about html, but will have a look to see what I might be able to do with this.

Well the Google Maps API is interfaced with using javascript and displayed using a browser, html and javascript for dynamic changes/updates.

Hi, so I have got a bit further with this and now have more of a vba issue than anything to do with Google maps.

My code below takes the input from a html file and merges with the lat longs from my data sheet but when attempting to create a new html file I get a "Bad file mode" warning on the Write #1, allText

VBA Code: 
Global LatLongs As String

Sub ConstructLatLongList()

    Dim c As Range
    Dim wsht As Worksheet
    Dim lr As Long
    Dim Latitude, Longitude As String

    Set wsht = ThisWorkbook.Sheets("Mapping Data")

    lr = wsht.Cells(Rows.Count, "A").End(xlUp).Row
    LatLongs = "var locations = [" & vbNewLine

    For Each c In wsht.Range("A2:A" & lr)
        Latitude = Cells(c.Row, "A").Value
        Longitude = Cells(c.Row, "B").Value

        LatLongs = LatLongs & "      ['" & Format(Cells(c.Row, "C"), "hh:mm") & " - " & Cells(c.Row, "D") & "', " & _
                   Latitude & ", " & Longitude & "],"

        If c.Row <> lr Then
            LatLongs = LatLongs & vbNewLine
        End If
    Next c

    LatLongs = Left(LatLongs, Len(LatLongs) - 1)

    'Debug.Print LatLongs

End Sub

Sub CreateHtmlFile()

    Dim text As String, allText As String
    Dim lineNumber As Integer

    ' Open read handle.
    Open "C:\users\me\desktop\new 2.html" For Input As #1

    allText = ""
    lineNumber = 0

    Do Until EOF(1)
        lineNumber = lineNumber + 1
        Line Input #1, text
        allText = allText & vbCrLf & text
        'Debug.Print allText
    Loop
    
    Call ConstructLatLongList
    
    allText = Replace(allText, "var locations = [", LatLongs, 1, , vbTextCompare)

    ' Close read handle.
    Close #1

    ' Output the new text to a separate file.
    Open "C:\users\me\desktop\newmap.html" For Input As #1

    Write #1, allText
    Close #1

End Sub

My original html file looks like:

  <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.1.min.js"></script>
</head> 
<body>
  <h3>My First Map </h3>
  <body bgcolor="#9fb3f5">    
  <div id="map" style="width: 100%; height: 550px;"></div>

  <script type="text/javascript">

    //var image = 'http://maps.google.com/mapfiles/kml/pushpin/red-pushpin.png'

    var image = 'output-onlinepngtools.png'   

    var locations = [
    ];

    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 25,
      mapTypeId: google.maps.MapTypeId.ROADMAP  
    });

    var infowindow = new google.maps.InfoWindow();

    var marker, i;
    var markers = new Array();

    for (i = 0; i < locations.length; i++) {  
      marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[1], locations[2]),
        icon: image,
        map: map
      });

      markers.push(marker);

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
          infowindow.setContent(locations[0]);
          infowindow.open(map, marker);
        }
      })(marker, i));
    }

    function AutoCenter() {
      //  Create a new viewpoint bound
      var bounds = new google.maps.LatLngBounds();
      //  Go through each...
      $.each(markers, function (index, marker) {
      bounds.extend(marker.position);
      });
      //  Fit these bounds to the map
      map.fitBounds(bounds);
    }
    AutoCenter();

  </script> 
</body>
</html>


This should then output the following

Change:
VBA Code: 
Open "C:\users\me\desktop\newmap.html" For Input As #1 
Write #1, allText
To:
VBA Code: 
    Open "C:\users\me\desktop\newmap.html" For Output As #1
    Print #1, allText
(Write # puts quotes around string variables)
