I discover that when i recounting more then 200 QT on one sheet with this
simply code



Set qt_data = result_sheet.QueryTables.Add("ODBC;DSN=Excel Files;DBQ=" +
ActiveWorkbook.Name + ";DefaultDir=" + ActiveWorkbook.Path +
";DriverId=790;MaxBufferSize=2048;PageTimeout= 5;",
result_sheet.range("AA1"), sql_str)

With qt_data
.PreserveFormatting = True
.FieldNames = False
.BackgroundQuery = False
.AdjustColumnWidth = False
.RefreshStyle = xlOverwriteCells
.Refresh
End With
qt_data.Delete



my EXCEL.exe process (2003 ver.) becomes very slow, "hard" (~300-400 Mb) and
"unstoppable" (closing frames, but not unload process)

Can you give me any advice?
