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.

do not cpy structure to string, use byte array instead. caz if some  string is member of structure, u will b in trouble.
