Subtraction of DateTime in a Cell formula

Hello,


As an example I need to pass the following string to the formula accessor of the Aspose.Cells.Cell object:

"“12 January 2010 18:30:00” -"12 January 2010 18:15:00"“

When I try this the DoubleValue accessor of the Cell throws an exception. I’ve tested this string format in Microsoft Excel, which handles it fine. I’ve also tested the following:

”“12 January 2010” -"12 January 2010""

which works fine on the Cell object, however I need the time component factored in as well.

Can you please tell me the format of the string I need to pass?

Hello,


Thank you for the quick update. The fix you provided fixes the issue for a date with a time that includes seconds, like the following:

"“12 January 2010 18:30:05” -"12 January 2010 18:15:10"“

However, if there were no seconds then the string representation of the Date time will be as follows and the same exception is being thrown:

”“12 January 2010 18:30” -“12 January 2010 18:15"“

Furthermore, if the seconds or minutes are provided but are zero then the same exception is thrown:

”“12 January 2010 18:30:00” -“12 January 2010 18:15:00"”

”“12 January 2010 18:00” -"12 January 2010 18:05""

Finally, if the calculation has a valid hour, second and/or minute component then the DoubleValue returned for the cell appears to always be 8.0.

Hi David,

Well, I tested your scenario with v4.8.2.1 but could not find any issue. It works as MS Excel.

Here is my sample code:

Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];

Aspose.Cells.Cell cell1 = worksheet.Cells[“A2”];
cell1.Formula = "=“12 January 2010 18:30:00”-“12 January 2010 18:15:00"”;
Aspose.Cells.Cell cell2 = worksheet.Cells[“A3”];
cell2.Formula = "=“12 January 2010 18:30”-“12 January 2010 18:15"”;
Aspose.Cells.Cell cell3 = worksheet.Cells[“A4”];
cell3.Formula = "=“12 January 2010 18:00”-“12 January 2010 18:05"”;

workbook.CalculateFormula();

MessageBox.Show(cell1.DoubleValue.ToString());
MessageBox.Show(cell2.DoubleValue.ToString());
MessageBox.Show(cell3.DoubleValue.ToString());

workbook.Save(“e:\test\jj22sdfsdfd11out_hyperlink.xls”);


Could you create a sample code/application to post it here to show the issue, we will check it soon.

Thank you.

Disregard my last email, the fix works perfectly :slight_smile:


Thank you very much.
