But when i try to retireve the inserted values from BDB i am geting only the latest record for Value.
[code]//KEY
char key[512];
//VALUE
typedef struct
{
char *remValues[10];
}valuestr;
static valuestr vstr;
Dbc *dbcObj;
Dbt dbtKey,dbtValue;
// I am dynamically allocating memory for Value str using malloc example as below.
vstr.remValues[0] = (char *)malloc(50);
while(!feof(inFile))
{
//getting key from input file
strcpy(buf, <value1>); //value1 comes from input file
//getting Value from input file
memset(vstr.remValues[0],0,50);
sprintf(vstr.remValues[0],"%d",<value2>); //value2 comes from input file

That would be the case as you are always loading values into the very first element of the array remValues...instead of filling all 10 of them with values read from the input file...which I highlighted in the code above.
