Changing odbc timeout - c++

Question

I am trying to run following stored procedure using ODBC:
CREATE PROCEDURE [dbo].[Add]
--WITH ENCRYPTION
AS
DECLARE #LoopVar BIGINT = 0
, #MaxVar BIGINT = 0
, #rows BIGINT = 0
SET #LoopVar = 1
set #rows = 125000
insert into debug values(987654321)
insert into debug values(#LoopVar)
insert into debug values(#rows)
WHILE(#LoopVar <= #rows)
BEGIN
SET #LoopVar = #LoopVar + 1
WAITFOR DELAY '00:00:01'
insert into debug values(#LoopVar)
END
insert into debug values(123456789)
GO
The C++ code for running the stored procedure is:
RETCODE rc = SQL_SUCCESS;
HENV henv = SQL_NULL_HENV;
HDBC hdbc = SQL_NULL_HDBC;
SQLHSTMT hstmt = SQL_NULL_HSTMT;
SQLTCHAR * pszConnection = _T("DRIVER={SQL Server Native Client 10.0};Server=myserver;Trusted_Connection=Yes;Initial Catalog=testdb;");
SQLTCHAR * pszInsertStmt = _T("{call [testdb].[dbo].Add}");
SQLLEN cbParamLength;
SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HENV, &henv);
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (SQLPOINTER)SQL_OV_ODBC3, 0);
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
SQLSetConnectAttr( hdbc, SQL_ATTR_LOGIN_TIMEOUT, reinterpret_cast<SQLPOINTER>(600), SQL_IS_UINTEGER);
SQLDriverConnect( hdbc, NULL, pszConnection, SQL_NTS, NULL, 0, NULL, SQL_DRIVER_NOPROMPT);
SQLAllocHandle(SQL_HANDLE_STMT, hdbc, &hstmt);
SQLSetStmtAttr(hstmt, SQL_QUERY_TIMEOUT, (SQLPOINTER)12000, SQL_IS_UINTEGER);
SQLSetStmtAttr(hstmt, SQL_ATTR_QUERY_TIMEOUT, (SQLPOINTER)12000, SQL_IS_UINTEGER);
SQLINTEGER attr;
rc = SQLGetStmtAttr( hstmt, SQL_ATTR_QUERY_TIMEOUT, &attr, 0, NULL ) ;
rc = SQLGetStmtAttr( hstmt, SQL_QUERY_TIMEOUT, &attr, 0, NULL ) ;
rc = SQLGetConnectAttr(hdbc, SQL_ATTR_CONNECTION_TIMEOUT, &attr, 0, NULL);
rc = SQLExecDirect(hstmt, pszInsertStmt, SQL_NTS);
if (!SUCCESS(rc)) {
if (hstmt)
PrintError(SQL_HANDLE_STMT, hstmt);
if (hdbc)
PrintError(SQL_HANDLE_DBC, hdbc);
if(henv)
PrintError(SQL_HANDLE_ENV, henv);
}
if (hstmt)
SQLFreeHandle(SQL_HANDLE_STMT, hstmt);
if (hdbc) {
SQLDisconnect(hdbc);
SQLFreeHandle(SQL_HANDLE_DBC, hdbc);
}
if (henv)
SQLFreeHandle(SQL_HANDLE_ENV, henv);
I have set query time in the code above. The connection time out is 0 (which I believe means no timeout). But no matter what I do, the stored procedure times out in 78 seconds. Does any one have any idea as to what I should do so that stored procedure can run indefinitely?
Please note if I run the stored procedure from SQL Server Management Studio directly, it works just fine..
Thanks in advance,

If anyone interested, the solution was to put "SET NOCOUNT ON" as the first line in stored procedure.
