Bcp_sendrow Causing Unhandled Exception (0xC0000005: Access Violation Reading Location 0x00000123)

Hi,

Background:

This could be a simple C++ issue as I am not that familiar with the language. I am trying to prototype a small program to test the performance of inserting data using the BCP interface. I want to BCP data that my program generates and passes via program variables.



I have narrowed the issue down to a sprintf call. Following are two variations of the code - one that works and one that does not. The error happens when I try to execute the bcp_sendrow() call.



What is the appropriate way to create / send string data to the BCP interface. Any good examples available? I have created the following from the BulkCopyFromVariables example on the Microsoft SQL Server downloads site.



Thanks in advance, Kerry

for(idx=1; idx<=5; idx++){
//sprintf(k1, "%d", idx); //does not work...
sprintf(k1, "oo"); //works....

if ( (SendRet = bcp_sendrow(hdbc1) ) != SUCCEED ) {
printf("bcp_sendrow(hdbc1) Failed

");
Cleanup();
return(9);
}
}
