Assinging dynamically allocated CStrings 2 1

[reneb]

I don't know if you read my previous question because it strongly relates to this one. I have dynamically created a structure of type SiteStruecture using this time malloc instead of calloc.
struct SiteStructure
{
int numOfSect;
double easting;
double northing;
CString siteCodeStr;
CString prdPath[6];
CString prdNames[6];
double eIRP[6];
int angle[6];
SiteStructure * nextSite;
}

when I try to assign values to the siteCodeStr, which is a CString I get a memory access violation error, When I try to assing the doubles or ints, I have no problem. Does any one have a clue as to what is going on? Desparate, please help. Thanks in advance.

Dear reneb,

malloc, calloc and such do not 'construct' objects, they just allocate memory. Use the 'new' operator to construct your structure and the CString constructors will be called.

struct SiteStructure* pSStruct = new SiteStructure;
pSStruct->siteCodeStr = "hello CString";
cout << (LPCSTR)pSStruct->siteCodeStr << endl;

Hope this helps
