Excel 2007 user warning when opening xls files
- by J Angwenyi
I am getting the following error warning when opening an xls file generated using 'CarlosAg.ExcelXmlWriter.dll' using Excel 2007
The file you are trying to open,'', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
Any idea how to resolve?
