MapForums

One more try, could somebody help:
I want to use MapPoint Control in my VC++ FormView based application. In the CFormView object there is the following code

void CMapPointTest1View::OnInitialUpdate()
{

..................

VARIANT var;
var.vt = VT_INT;
var.intVal = 1;
CMap1 map = m_MapPoint.NewMap(var);
}

m_MapPoint is the CMappointCtrl object to which I connected the MapPoint control element (CMappointCtrl object).
A map appears. But once I click in it, MapPoint collapses. There must be a solution.
Thanks! Jörg

do you try to interact with the map in your source code when you click in it ?

Not yet, what you see is the only code written. I click the map - and MapPoint collapses.

Hi,

I've found the following code in this forum:
I hope it gives some help

Yes, I've seen this already. But from where to hell does he/she get the
m_pCtrlCont pointer?

The following is the solution:

1. Add the follwing function into the CMappointCtrl object:

COleControlSite* CMappointCtrl::GetCtrlSite()
{
return m_pCtrlSite;
} which returns the control site.

2. Add #include "OccEx.h" into your FormView or Dialog object or where you want to display the map.

3. In the FormView or Dialog add the following to OnInitialUpdate():

void CMapPointTest1View::OnInitialUpdate()
{
............................

SetCapture();
// Open the MAP
VARIANT var;
var.vt = VT_INT;
var.intVal = 1; //geoMapUSA
CMap1 map = m_MapPointCtrl.NewMap(var);

// This fixes the problem
m_pCtrlCont->OnUIDeactivate(m_MapPointCtrl.GetCtrlSite());
m_pCtrlCont->OnUIActivate(NULL);
SetFocus();

ReleaseCapture();
}

m_pCtrlCont then returns the control container.
It is stable (as far as I see now).

Thanks to everyone

Hi guys,

I've used this style of importing Mappoint, but when I close my app I get this:
First-chance exception in MapPrac.exe (KERNEL32.DLL): 0x800706BE: (no name).

And I've just used this code:
Everything works fine and the app doesn't collapse, but it just doesn't exits mappoint the right way.
I hope somebody can explain this.

Does somebody has experience with another way of importing Mappoint in VC++? e.g. importing the mappoint library? How can I show the map? Normally I've done this by importing ActiveX and VC++ autamatically generates a MapControl I can drag 'n drop where I want on my GUI, to display the map. With importing library I don't know how to do that. I've read the articles how to do that, but not how to show the map.

Hi,

Is this the object model that you use or do you have put the activeX control on your form ?

Thank you for your reply Wilfried,

Well it's a bit fuzzy what ActiveX or COM is.
But what I know is that ActiveX IS COM, the only difference is that ActiveX has wrapped a COM object so that it can be easely used by VB or VC++, especially VB (ActiveX was developed for VB, I've read once), those guys are spoiled to much .

But I guess sometimes ActiveX works well for VB but not for VC++. I've imported Mappoint as an ActiveX, and it didn't work correctly, I had to add some code's I've copied from a post of someone here on this forum (I don't remember which one it is). That was a workaround, but I don't know if it was correct, I had no choice. Maybe that's why MS has no documents on how to use Mappoint with VC++.

Another way to import Mappoint, is to import it's library .tlb into VC++. I haven't tried this way yet, but maybe this way is a better way.

But does somebody imported Mappoint as an ActiveX without First Exception for terminating Mappoint?

Thank you.

Hi,

Ok, I think this article explain some use with the type library (what I meant with the object model), as whell the activex control:

Using the OCX from VC++
