Hang when loading a document. *.xls. Conditional formatting

Hi,

I use Aspose.Cells by COM. When I try to load a document, my application hangs. I try to load this document directly by C#, but it’s all work properly.
The problem occured in version 7.0.3.4. I checked version 7.0.3.3 and it has no problem.

I created two simple documents:
1. Document in *.xlsx format with conditional formatting in first cell. This document loads properly;
2. Document in *.xls format. It created by conversion first document to *.xls format. This document hangs.

I also created two simple Delphi projects for reproduce this problem. Before start the application you must to register Aspose.Cells.dll in the same directory.

When I loaded this application with AQtime 6, I got next messages with exception:

Hi,

Hi Alex !

Please try our com demo project in attachment , we do not find issue with your template files

Hi Fisher Wang,

Thank you for demo project.

I found the problem. The Delphi and Visual Studio have different default settings. Delphi create exception (Delphi 2009 hangs), When the Float Overflow occurs.

I also found the fix for this problem (https://forums.embarcadero.com/thread.jspa?messageID=334125&tstart=0), but those exceptions may be a cause of incorrect values in components. It will be better, if you fix these exceptions.

Thank you,

Hi,

We will look into and fix the problems if any and update you asap.

Hi,

You may already found Set8087CW($133F) can solve your issue.

We do not catch any “Divided by zero exception” in our code.

So we think we can close this issue.

Hi,
Yes, as I written in previous post I found solution for this problem. I call this method before and after all the methods from Aspose.Cell.
Yes, you can close this ticket.

Thank you,
Alex Shloma

Hi,
