I want to program using VC6.0,And when I use its OCX to open a specfic mappoint,by the way ,it is based on dialogue,it can pen the map,but it will report a error .and the code is
BOOL CRouteDirectionDlg::OnInitDialog()
{
CDialog::OnInitDialog();
..........
this->m_ctlMappoint.OpenMap("C:\\lazone.ptm");
...
}

try

m_ctlMappoint.OpenMap("C:\lazone.ptm");

instead, and make sure the map actually exists. Whats the error?

No, the double backslash looks right for C. The backslash is used as an escape character for producing special characters, eg. the newline is "\n"
To produce a conventional backslash you just repeat it.

I have an article pending (Eric said it should be published next week) about using MapPoint from VC++ without MFC.
My code has tested great with the Microsoft and Intel compilers, and I've had someone test against C++ Builder (that required a few changes to get it to work).

I haven't tried to programmatically open a pre-existing map, but if you have a wider problem with the COM interface, it might help identify it?

// Bidouille pour eviter l'erreur sur l'assert
SetCapture();
// Fin bidouille

// Ouverture de la carte mappoint
_variant_t tVar;
short Var = 2;
tVar = Var;
_cMap = m_mapPointCtrl.NewMap(tVar);

// Bidouille necessaire pour eviter un plantage (probleme d'activation du controle)
m_pCtrlCont->OnUIDeactivate(m_mapPointCtrl.GetCtrlSite());
m_pCtrlCont->OnUIActivate(NULL);
SetFocus();
ReleaseCapture();
// Fin bidouille
