QAxObject Importing Excel named ranges using MS Query

[simonb]

Hi all, I got xlsm file format and I defined a table with name range.
I can get the table name, but I didn't succeed to recive his ranges I tried this code



QAxObject* _excel = new QAxObject( "Excel.Application", 0 );
QAxObject* workbooks = _excel->querySubObject( "Workbooks" );
QAxObject* workbook = workbooks->querySubObject( "Open(const QString&)", fileName );
QAxObject* sheets = workbook->querySubObject( "Worksheets" );
//worksheets count
int count = sheets->dynamicCall("Count()").toInt();
count = sheets->property("Count").toInt();
for (int i=1; i <= count; i++) //cycle through sheets
{
//sheet pointer
QAxObject* sheet = sheets->querySubObject( "Item( int )", i );
QString s_name = sheet->dynamicCall("Name()").toString();
QAxObject* tables = sheet->querySubObject("Names");
int table_count = tables->dynamicCall("Count()").toInt();
table_count = tables->property("Count").toInt();
qDebug("sheet name :%s",s_name.toAscii().constData());
for (int j=1; j <= table_count; j++) //cycle through tables
{
QAxObject* table = tables->querySubObject( "Item( int )", j );
QString t_name = table->dynamicCall("Name()").toString();
qDebug("\ttable[%d]: %s",j,t_name.toAscii().constData());
QAxObject * usedrange = table->querySubObject("UsedRange");
QAxObject * rows = usedrange->querySubObject("Rows");
QAxObject * columns = usedrange->querySubObject("Columns");
int intRowStart = usedrange->property("Row").toInt();
int intColStart = usedrange->property("Column").toInt();
int intCols = columns->property("Count").toInt();
int intRows = rows->property("Count").toInt();
qDebug("\t\t[ Cells(C%d:C%d) , Rows(R%d:R%d) ]",
intColStart,intCols,intRowStart,intRows);
}
}
_excel->setProperty("DisplayAlerts", 0); //remove alert when close the file
workbook->dynamicCall("Close()");
_excel->dynamicCall("Quit()");



Got the error:
