MapForums

Hi,

I just started to test mappoint 2004 in VB.NET and have no experience in vb.net.

I can put the mappointcontrol1 on the windows form , when I try to put code (in the form load event or button click event)

mappointcontrol1.newmap =>still ok

but when I add geoMapEurope this is not working anymore.

( Of course I installed mappoint 2004 europe)

vb.net put a line under geoMapEurope and gives a debug error after starting.
In vb6 it works perfect....
What can I do?

Thanks for help

Place a MapPoint control on the form, and then add the following code to the 'Form1_Load':
(In this example the control on the form is called 'MappointControl'.)

You may want to try adding this code to a button to move to a specified lat/lon...
(This uses three textboxes - txtLat,txtLon, and txtAlt for the lat,lon,and altitude for viewing the map.)

Hope this helps...

Hi Nick,

Thanks for your help, this way it (NewMap) works!!

I found out that Mappointcontrol.OpenMap("C:\test.ptm") works to if I save first a map.

In the object browser I found that the OpenMap method needs a string as an argument but the NewMap method needs an object.

I think this is the difference with vb6 no?

Best regards,

Wim

I've only started using MP2004 with VB.Net fairly recently, and looking round the web at sample code, it seems that there are quite a few 'subtle' changes in the syntax between MP2002 and 2004. Just to make it worse, most of the code 'in the wild' is for VB6, which doesn't really help very much!!

You've probably just found your first example!
