I am working on a tracking system and mappoint is my mapping software. I am using VB for my programming. At the moment i am doing geofencing and what i want to do is be able to get the lats and longs of a location where i click on the map...is this possible? thanks

Yes, here is alink to the article that will help you.

You know, I don't think that's the answer he's looking for, though I could be wrong. If I'm not, I'm looking for the same answer.

The article points to a routine that is well known around here for extracting the lat/long from a pushpin. But what if you are just trying to react to a users click of a spot on the map, similar to what the location tool does.....as you move about on the map it reports the lat/long.

The closest thing I can get to that involves the user having to place a pushpin at the desired location, then push a VB button.....which then executes the above.......as long as the user doesn't change the name of the pushpin.

Look at the MouseDown or MouseUp event

X ByVal Long. The X coordinate of the mouse pointer relative to the map window, in pixels.
Y ByVal Long. The Y coordinate of the mouse pointer relative to the map window, in pixels

In that event you will get the x/y of the mouse.

Now take a look at the XYToLocation method. Use it to take the x/y of the mouse and get a location object. At this point you should have the required stuff to use the calcpos function to return the lat/lon.

Also, there is another article that uses the same concept in .net to demonstrate the location sensor (uses the mousemove event)

Where have you been all my life?

yeah this is what i have come to but i dont know how yo use the function calcpos. could you give an exapmle of how to use it? I keep getting an error, object variable or with block variable not set.

Regards,

Ok, Let me know if this works for you.

Visual Basic 6
Assumes you have the CalcPos Sub and the Function Arccos by Author Gilles Kohl in you project. http://www.mp2kmag.com/articles.asp?ArticleID=13

MapPointControl.ocx is on Form1
One Command Button (Command1)

Code:

Public ilat As Double
Public ilon As Double

Private Sub Form_Load()
Dim objmap As MapPointctl.Map
Set objmap = MappointControl1.NewMap(geoMapNorthAmerica)
End Sub


Private Sub Command1_Click()
Dim objmap As MapPointctl.Map
Set objmap = MappointControl1.ActiveMap
Dim objLoc As MapPointctl.Location
Dim objPushpin As MapPointctl.Pushpin
Set objLoc = objmap.FindResults("Seattle, WA")(1)
Set objPushpin = objmap.AddPushpin(objLoc, "My Test Pushpin")
CalcPos objmap, objPushpin.Location, ilat, ilon
MsgBox ilat & ", " & ilon
End Sub

excellent!! the only problem is, is sometimes i'm getting "The parameter is incorrect" Does this work all over the world?
