HOWTO: Use the MapPoint 2002 Control and Automation with Visual Basic to Save a Map as HTML

SUMMARY

MapPoint 2002 includes an ActiveX control, Microsoft MapPoint Control 9.0, that provides a convenient way to use MapPoint 2002 functionality on a Visual Basic form. A map that you create by using this control may be saved as a MapPoint file (.ptm), but not as an HTML file. To create an HTML file from a map, you can automate MapPoint 2002 to copy a .ptm file-format map to an HTML file that can be accessed by using a Web browser.

This article provides sample code that shows you how to create a map by using the MapPoint 2002 control on a Visual Basic form and how to automate MapPoint 2002 to export the map file to HTML.

MORE INFORMATION

In Visual Basic 6.0, create a Standard EXE project.

Form1 is created by default.
Size Form1 so that it fills the maximum available space both vertically and horizontally.
On the Project menu, click References. Select the Microsoft MapPoint 9.0 Object Library (North America) and then click OK.
Add a MapPoint control and three CommandButton controls to Form1.
Size the MapPoint control so that it fills as much of Form1 as possible. Leave room for the CommandButton controls.
Set the Caption property for Command1 to Make Route Map, the Caption property for Command2 to Export Map as HTML, and the Caption property for Command3 to Close the Project.

Add the following code to the code module of the form:

    Public oApp As mappointctl.Application
    Public oMap As mappointctl.Map
    Public oRoute As mappointctl.Route
    Public oWaypoints As mappointctl.Waypoints
    Public oResults As mappointctl.FindResults
    Public StartPoint As mappointctl.Waypoint
    Public MidPoint1 As mappointctl.Waypoint
    Public MidPoint2 As mappointctl.Waypoint
    Public EndPoint As mappointctl.Waypoint
    Public oRootApp As MapPoint.Application

Private Sub Command1_Click()
        Set oMap = MappointControl1.ActiveMap
        Set oRoute = oMap.ActiveRoute
        Set oWaypoints = oRoute.Waypoints
        
        Set oResults = oMap.FindAddressResults("16011 N.E. 36th Way", "Redmond", "", "WA", "98052", 244)
        If oResults.Count >= 1 Then
            Set StartPoint = oWaypoints.Add(oResults.Item(1), "Loc1")
        End If

        Set oResults = oMap.FindAddressResults("11235 SE 6th Street", "Bellevue", "", "WA", "98004", 244)
        If oResults.Count >= 1 Then
            Set MidPoint1 = oWaypoints.Add(oResults.Item(1), "Loc2")
        End If
        
        oRoute.Calculate ' This is leg 1
        
        Dim dLeg1 As Double
        dLeg1 = oRoute.DrivingTime
        
        ' End Leg 1.
        
        Set oResults = oMap.FindAddressResults("22011 SE 51st Street", "Issaquah", "", "WA", "98027", 244)
        If oResults.Count >= 1 Then
            Set MidPoint2 = oWaypoints.Add(oResults.Item(1), "Loc3")
        End If
        
        oRoute.Calculate
        
        Dim dElapsedTime1 As Double
        dElapsedTime1 = oRoute.DrivingTime
        Dim dLeg2 As Double
        dLeg2 = dElapsedTime1 - dLeg1
        
        ' End trip time to this waypoint, and Leg 2 drive time.

         Set oResults = oMap.FindAddressResults("16011 N.E. 36th Way", "Redmond", "", "WA", "98052", 244)
        If oResults.Count >= 1 Then
            Set EndPoint = oWaypoints.Add(oResults.Item(1), "Loc1")
        End If
        
        oRoute.Calculate
        
        Dim dElapsedTime As Double
        Dim dLeg3 As Double
        dElapsedTime = oRoute.DrivingTime
        dLeg3 = dElapsedTime - dElapsedTime1
        
        ' End trip to third waypoint and Leg 3.
        
        Dim StartDate As Double 'DateTime
        Dim Mid1Date As Double  'DateTime
        Dim Mid2Date As Double  'DateTime
        Dim EndDate As Double   'DateTime
        
        Dim StopTime As Double
        StopTime = 0.3 * geoOneHour
        
        StartDate = TimeValue("8:00:00 AM")
        
        StartPoint.PreferredDeparture = StartDate
        Mid1Date = StartDate + dLeg1 + StopTime
        MidPoint1.PreferredDeparture = Mid1Date
        Mid2Date = Mid1Date + dLeg2 + StopTime
        MidPoint2.PreferredDeparture = Mid2Date
        
        MappointControl1.SaveMapAs FileName:="C:\Atestmap.ptm"
        MappointControl1.ActiveMap.Saved = True
End Sub

Private Sub Command2_Click()
    Set oRootApp = CreateObject("Mappoint.application")
    oRootApp.OpenMap "C:\Atestmap.ptm"
    oRootApp.ActiveMap.SaveAs "C:\Atestmap.htm", geoFormatHTMLMapAndDirections
End Sub

Private Sub Command3_Click()
    If Not (oRootApp Is Nothing) Then
        oRootApp.ActiveMap.Saved = True
        oRootApp.Quit
        Set oRootApp = Nothing
    End If

    If Not (oMap Is Nothing) Then
        oMap.Saved = True
        MappointControl1.Visible = False
        Set oApp = Nothing
        Set oMap = Nothing
        Set oRoute = Nothing
        Set oWaypoints = Nothing
        Set oResults = Nothing
        Set StartPoint = Nothing
        Set MidPoint1 = Nothing
        Set MidPoint2 = Nothing
        Set EndPoint = Nothing
    End If
    Unload Me
End Sub

Private Sub Form_Load()
    MappointControl1.NewMap (geoMapNorthAmerica)
End Sub

To test the program, follow these steps:
1. Press F5 to run the program.
2. Click Make Route Map.
3. After the map displays the route, click Export Map as HTML and then click Close the Project.
4. Start your Web browser and open C:\Atestmap.htm.
