Hello,
I am currently working with Origin 8.0951 (B951) on Windows XP, and trying to export some calculated datas from a worksheet to a database like SQL following the present example : http://www.originlab.com/www/helponline/Origin/en/programming/mergedProjects/OriginC/OCGuide/Exporting_into_a_Database.html.
#include <origin.h>
#define STR_DB_CONN "Driver={MySQL ODBC 3.51 Driver}; Server=Lintilla;Port=3306;Option=4;Database=Analysis;UID=test;PWD=test;"
#define STR_QUERY "Select * from FittingSummary"
bool write_wks_to_db()
{
Worksheet wks = Project.ActiveLayer();
if ( wks )
return false;
//connect to database "Analysis" on "Lintilla"
string strConn = STR_DB_CONN;
string strQuery = STR_QUERY;
Object oConn;
oConn = CreateObject("ADODB.Connection");
if ( !oConn )
return error_report("Fail to create ADODB.Connection object!");
oConn.Open(strConn);
Object oRecordset;
oRecordset = CreateObject("ADODB.Recordset");
if ( !oRecordset )
return error_report("Fail to create ADODB.Recordset object!");
//open recordset
oRecordset.CursorLocation = 3; //adUseClient, please refer to MSDN for details
oRecordset.Open(strQuery, oConn, 1, 3); //adOpenKeyset, adLockOptimistic
int iRowBegin = 0, nRows = 8; //8 rows
int iColBegin = 0, nCols = 9; //9 columns
//LAYWKSETRECORDSET_APPEND for appending new recordset;
//LAYWKSETRECORDSET_REPLACE for replacing existing recordsets.
int nOption = LAYWKSETRECORDSET_APPEND; //append.
int nRet = wks.WriteRecordset(oRecordset, nOption,
iRowBegin, nRows, iColBegin, nCols);
return (0 == nRet);
}
Some errors occured when compiling this piece of code.
It seems that WriteRecordset is not defined or does not have matching prototype, LAYWKSETRECORDSET_APPEND and LAYWKSETRECORDSET_REPLACE are not defined.
Is anybody think that this feature is not present within this version, do i have to do an upgrade or are there hints and tricks to accomplish such opperations ?
Could you help me please?
Thanks,
Best regards.

Hi,
Yes, you are right. The version you are using does not include LAYWKSETRECORDSET_APPEND yet. Please update to Origin 8 SR6 from this page and then try again.
