We updated to aspose.cells 3.7.0.0 and ran into a problem. When we save aspose generated excel, then re-open it. it will display"data lost" message box and image will be lost. I've attached our template.
I opened and saved this file with Aspose.Cells and don’t find any problem. Could you please give me more detail information about this problem? Could you post your generate file here?
save the template file to your C: as report.xls, then run the following
Dim excelapp As Aspose.Cells.Excel = New Aspose.Cells.Excel
excelapp.Open("c:\report.xls")
excelapp.Save("c:\hhhh.xls")
System.Diagnostics.Process.Start("c:\hhhh.xls")
After you see the file open on your screen, click save as... say save as c:\h1.xls. Close the file, click open from Excel, pick c:\h1.xls you just saved. you will see the message box "File error: Data may have been lost", and image is gone.
