While excel works 'by row' first top row from left to right and than that downwards row by row.Īs the results of some operations sometimes depend on the order of operands, differences show up. calculate sheets / ranges / operands in different orders: apply different rounding / 'snap-to-zero' to results, apply different rounding to input values, LibreOffice Calc and Microsoft Excel often compute slightly different results.Įxpect (often invisible) deviations between results from Calc and Excel as they: M圜onnection = New ("provider=.12.0 Data Source='" & OpenFileDialog.FileName & "' Extended Properties='Excel 12.LibreOffice Calc cannot properly work with Microsoft Excel's xlsm files. M圜onnection = New ("provider=.12.0 Data Source='" & OpenFileDialog.FileName & "' Extended Properties='Excel 12.0 Xml HDR=YES IMEX=1 '") (1000) 'Esperar a que termine la instancia Office (await libreOffice thread)ĭim M圜onnection As 'Preparar conexión para realizar consulta tipo sql (preparing connection)ĭim M圜ommand As InstOffice = objOffice.createInstance(".Desktop")ĭim myDoc = instOffice.loadComponentFromURL("file:///" & ("\", "/"), "_default", 0, obj)ĭim hojas = myDoc.getSheets().getElementNames() 'Obtener nombres de las hojas de calculo (get Spreadsheet names) ObjOffice = CreateObject("") 'preparar instancia libreOffice (prepare libreOffice instance) If (OpenFileDialog.ShowDialog() = .OK) Then OpenFileDialog.Filter = "Spreadsheets (*.xls*)|*.xls*" This is a part of VB Sample in which i got connection to oledb to create some queries. If you had installed LibreOffice look for cli_basetypes.dll, cli_cppuhelper.dll, cli_oootypes.dll, cli_uno.dll, cli_ure.dll, cli_uretypes.dll then add references to your project, it must work for you, i also installed "Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats" and "Microsoft Access Database Engine 2010 Redistributable" (to get ACE.OLEDB.12.O connection without complete Office installation).
