Hello,

We have an issue with DateTime :
We store a DateTime in a cell and set the format "m/d/yyyy".
Spire is in Invariant culture and Excel is in French culture.

When we open Excel workbook, the cell is in Personalize format.
We need the predifined format (in the date tab)

How to give that ?

Code: Select all
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

var workbook = new Workbook();
var worksheet = workbook.Worksheets.First();

worksheet.Range["B2"].Value2 = new DateTime(2017, 01, 30);
worksheet.Range["B2"].NumberFormat = "m/d/yyyy";

workbook.SaveToFile(Chemin + "Sample - Out.xlsx", ExcelVersion.Version2016);

Hello

We reproduce again this issue.

Maybe it's because our Excel is in french ?

Dear VincentB,

After further investigation, you are partly correct. The issue is caused by the culture setting, not just the French.
If you comment out the code below, the format would be correct.
Code: Select all
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

Anyway, I have posted the issue to our Dev team. once there is any progress, we will let you know.

Sincerely,
Betsy

Dear VincentB,

After further investigation, we found the solution. When setting the InvariantCulture, the date format should be equal to the format setting in control panel(please check on attachment). So please set the number format as below, which is date format in French.
Code: Select all
             worksheet.Range["B2"].NumberFormat = "dd/mm/yyyy";

If there is any question, please let us know.

Sincerely,
Betsy

Hello,

We need to define the format in an international style, because our application is used with Excel in English and French.
We also need the line below for other uses

Code: Select all
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;


Sincerely,

Vincent

Hi Vincent,

Thanks for waiting.
Now the issue has been fixed in Spire.XLS Pack(Hotfix) Version:7.12.109. And you could use the InvariantCulture and needn't to set the number format anymore. The result format will be date in any region.
Looking forward to your feedback.

Sincerely,
Betsy

Hello

We reproduce again with this code (All lines in this sample are required for us) :


Code: Select all
            Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

            var workbook = new Workbook();
            var worksheet = workbook.Worksheets.First();

            worksheet.Range["B2"].Value2 = new DateTime(2017, 01, 30);
            worksheet.Range["B2"].NumberFormat = "m/d/yyyy";

            workbook.SaveToFile(Chemin + "Sample - Out.xlsx", ExcelVersion.Version2016);


I attached our test result.
Value of B2 is correct (in formula editor : 30/01/2017)
NumBerFormat is set to Personalized "m/j/aaaa" (We need the NumberFormat "Date")

Do you need more informations ?

Best regards,

Vincent

Hi VincentB,

Thanks for your feedback.
In the hotfix, if you use InvariantCulture setting, please don't set the NumberFormat again, then the result format will be date in any region.
Code: Select all
            Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
            var workbook = new Workbook();
            var worksheet = workbook.Worksheets.First();
            worksheet.Range["B2"].Value2 = new DateTime(2017, 01, 30);
            //comment out this code.
            //worksheet.Range["B2"].NumberFormat = "m/d/yyyy";
            workbook.SaveToFile(Chemin + "Sample - Out.xlsx", ExcelVersion.Version2016);

And if you use both InvariantCulture and NumberFormat setting, the result format will depend on the format setting in control panel and I provided a screenshot before.

Sincerely,
Betsy

Hi,

Unfortunately, we need to set the NumberFormat : it's dynamically set in our app (Configured by User independently of the type of value)

After analysis, we can remove the line :
Code: Select all
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;



Regards,

Vincent
