I am not sure if I understood you. Do you want to copy all the structure as a single string ? If so, you can use memcpy.

struct myStruct {
 ...
 ...
} sTmp;

char szString[sizeof(myStruct)+1]={0}; // You must add a zero to terminate the string
memcpy(szString,&sTmp,sizeof(myStruct));

If you want to insert it to access, you need to use DB functions. Check the ODBC documentation.
