New Releases, Upgrades and Fixes

Where to find information about new Aspose.Cells releases?
Subscribe to the Aspose.Cells Blog to receive news about latest releases, hints and tips and other useful posts from the developers of Aspose.Cells.

Can I upgrade for free?
If you purchased a license for Aspose.Cells, it means you have a 1-year subscription for free upgrades to any new Aspose.Cells version that comes out. Any Aspose.Cells version released before the subscription expiry date - you can just download and use it.

If you want to check when your subscription expires, open the license file in Notepad (but take care not to modify and save the license file or it will no longer work) and see the SubscriptionExpiry field.


Technical Support

Is Aspose.Cells technical support free?
Yes, we provide unlimited free technical support for all users of our products including customers and evaluation.

The main avenue for technical support is the Support Forums. Post your questions and they will be answered quickly, but take time zones into consideration when expecting an answer.

I have a problem with Aspose.Cells for .NET or Aspose.Cells for Java, what should I do?
In order to help us solve your issues quicker, please follow these simple rules:

  1. Make sure you use the latest Aspose.Cells before reporting the issue, see Aspose.Cells Blog to find out about latest version.
  2. Browse through this FAQ, the Support Forum and the Aspose.Cells Documentation before reporting the issue. Maybe your question was already answered.
  3. If it still does not help, attach the original document (before processed by Aspose.Cells) and a fragment of your code that causes the problem. If you need to attach multiple files, zip them.
  4. Report one issue per thread. If you have another issue, report it in a separate thread.

Is it safe to attach my documents in the Support Forums?
Yes, it is safe. Your attachments can be downloaded only by you and Aspose staff.


Licensing

How to remove the evaluation watermark?
The evaluation watermark is inserted automatically when Aspose.Cells is used in evaluation mode (e.g. without a license). To remove the watermark, you need to buy a license and apply it programmatically before utilizing Aspose.Cells. You can also request a free 30-days temporary license to evaluate Aspose.Words without the message.

How to apply a license?
  1. Copy the license file into the folder that contains assemblies of your project or include the license file as an embedded resource into your project.
  2. Create an object of the Aspose.Cells.License class and call the SetLicense method passing only the file name of the license file without path:
[C#]

Aspose.Cells.License license = new Aspose.Cells.License();
license.SetLicense("Aspose.Cells.lic");

For more information about licensing see Aspose.Cells Documentation.

I applied a license like shown above, but the evaluation watermark is still there. What am i missing?

  • Make sure your call to SetLicense gets executed. Step through in the debugger.
  • Make sure your code does not catch and silence an exception thrown by Aspose.Cells licensing code. For example, Aspose.Cells will throw if it cannot find the license.
  • Make sure the input documents do not already have the evaluation watermark. Aspose.Cells does not delete existing evaluation watermarks.
  • Make sure SetLicense is executed before you instantiate any other Aspose.Cells object.

When I try to save an excel file with odd characters like é, è, â etc ... in the file name, it works if I save it directly on disk but if I use something like: excel.Save("André.xls", SaveType.OpenInExcel, FileFormatType.Default, Me.Response) It gives me the very odd filename André.xls ?
When you use OpenInExcel or OpenInBrowser option, the file name characters should be US-ASCII. It's not limited by Aspose.Cells, but HTTP protocols. You can refer to rfc2183.

I use the following code to set cell's style:

Excel excel1 = new Excel();
//Do something here
...
Excel excel2 = new Excel();
int styleIndex = excel2.Styles.Add();
Style styleHeading = excel2.Styles[styleIndex];
styleHeading.Name = "Heading";
styleHeading.Font.IsBold = true;
...
excel1.Worksheets[0].Cells["A1"].Style = excel2.Styles["Heading"];
excel1.Save("c:\\book1.xls", FileFormatType.Default);

But the formatting is lost in the created file.
The Style objects should be created in the same Excel object as Cell objects. So please change your code to:

int styleIndex = excel1.Styles.Add();
Style styleHeading = excel1.Styles[styleIndex];
styleHeading.Name = "Heading";
styleHeading.Font.IsBold = true;
...
excel1.Worksheets[0].Cells["A1"].Style = excel1.Styles["Heading"];
