News for GeneXus .NET Generator Users

GeneXus 9.0 Upgrade 1, to be released soon, includes the possibility of generating and reading Excel spreadsheets in Web without the need to install Office in the server.

This new way of generating and reading Excel spreadsheets allow using third party implementations to generate and read Excel spreadsheets in Web; that is to say Jakarta POI or ExcelLite, depending on each installation requirements.

The use of any of these new implementations for the generation and reading of Excel spreadsheets is performed in the same way as ExcelDocument data type, which allows using all the properties and methods of this data type. Once again, GeneXus developer achieves new features without the need to learn new concepts.

Besides, the decision of using Jakarta POI or ExcelLite is dynamically taken, through GxExcelI.dll.

The implementation with Jakarta POI has no cost, since the dlls can be download for free. Regarding ExcelLit, although it requires the use of a dll with a cost, there is the possibility of using the free version .

These new implementations can also be used in win environments. For web applications, the only thing to be taken into account is that the user executing the web objects must have writing rights in the directory selected to save the spreadsheet. Besides, once the spreadsheet is generated, there is the possibility of establishing a link to it so that the end user can open it or even save a copy in his local PC.

In the next issue of the GeneXus News, with GeneXus 9.0 Upgrade 1 already released, we will provide a general presentation of its new features, with detailed descriptions of some of the main ones.
