MapForums

Hello,

somebody used MapPoint with C++Builder 6?

I have not, but you might want to see the examples with Delphi and C++ on the site, search "site:mp2kmag.com Delphi" on Google.

If you figure out how to get MapPoint object library to work in C++ Builder, please let me know. I have gotten it to work using code similar to the Delphi code posted on this site, however, I have not been able to get all the functionality to work.

The MapPoint OCX will not work in Builder or Delphi, you have to use automaion using COM. Regrettably, I have had to use Visual Basic for now to make use of all the published MapPoint API.

I try to use Mappoint in my C++Builder-Application too.
Having read the Delphi-Example I have used an OleContainer.

In the Delphi-Tutorial the author uses this code to create
the OLE-Object.
I have translated it to C++ and the North-America-Map
appears in the Container.

The problem is, that i cannot get last line to work:
(Delphi in order to get control over the Map.

Can somebody help me?

I am only looking to put a pushpin on the map and change its position. I have created the Mappoint map in an OleContainer but can't find a way to get the control interface to do anything with the map. I am use the mouse on it, but that is all. I need to zoom and change the centre x & y position etc.

How do I get a pointer to the Map for use with the Map functions.

If I declare a Map object in C++ Builder such as this:

Map *pMap;

How do I actually use the OleContainer to point this pointer to a valid Mappoint map. I can see the functions, but the pointer is invalid when the programme runs. Hope this makes sense???

To use mappoint on your form in Cbuilder use the following (simple!) code. Remember to call 'ole->DestroyObject' before the form closes, otherwise an error comes up.

Don't forget to include
#pragma link "MapPoint_OCX"
in the top of the form, after #pragma package(smart_init)

succes, Jan Vieveen.


MapPtr map;
//---------------------------------------------------------------------------
void __fastcall TForm1::FormActivate(TObject *Sender)
{

ole->CreateObject("MapPoint.Map.EU.9", false);
ole->DoVerb(1);

map = ole->OleObjectInterface;
map->GoToLatLong(43, -3, 100);

}
