GeoCountry -> enum to CString conversion VC++ 7

Sample :

Code:

<..snip>

BSTR m_bstrRegion;
locHotSprings->StreetAddress->get_Region(&m_bstrRegion);
CString csRegion=Bstr2Cstr(m_bstrRegion);

BSTR m_bstrCountry;
//GeoCountry
MapPoint::GeoCountry MyGeoCountry;
CString csCountry;
locHotSprings->StreetAddress->get_Country(&MyGeoCountry );

str.Format(_T("%.3f km: %s, %s, %s %s %s %s"),adist, csStreet,csCity,csOtherCity,csRegion,csCountry,csPostal);
		
</snip>

Hi, could you help me on Howto convert the above MyGeoCountry
into String as Value or another way to get the actual
CountryCode by name out of the "simple" enum.. as CString.

(My first week in Visual C++ )

Thx in Advance

It doesn't look like MapPoint has a method to convert the enum into a string.

I would be tempted to create a lookup table and use that. The main problem with this is that there are some large gaps in the enum values.
So you could write a function/method that had lots of IFs (tedious).
Or, I'd create a lookup table using a map. MFC probably has an equivalent, but this could be a good time to learn about the STL (Standard Template Library). It handles a lot of the data structure things that MFC can do, but generally better/more flexible/faster.

You would need to manually create the map lookup table in an initialisation method. Then when you need the string, you would lookup the enum in the map, to get the string.

Something like this: (I haven't tested it: I prefer the STL string rather than the MFC CString, but I think they can be substituted in this case)

Code:

map< MapPoint::GeoCountry, CString >  Country_LUT;

Country_LUT[ 61 ] = CString("Denmark");
Country_LUT[109] = CString("Hungary");
// etc

// Use:

CString myCountryString = Country_LUT[ myCountryCode ];

That should get you on your way. I think the map<> can be replaced with an MFC collection, and I may have mis-translated my strings for CStrings.
If you're a beginner with C++, you might not immediately appreciate that STL is better - but it is worth learning in the long term.

Yes, but main Problem in your Solution is that i need to manually translate each Mappoint and we have already a German,Italian,English and more Versions.

i was pondering prior about the same :

char const fruitNames[] = { "State", "Orange", "Banana" }
std::string name = fruitNames[orange];

this would be a simple map, but i KNOW that it MUST be possible

Thx if someone could help me with a "real" inline solution.

Or maybe it is possible to get the name from the "Location and Scale" Toolbar or even if you try the save as function the predefined filename ends with the state..
so a map would be the worst solution in my mind..

Thx in advance
