we are facing an error intermittently which mentions Aspose.cells in the stack trace of the error page (PFA).

can you please help us here.

will installing aspose on the server help?

please feel free to call me at 9740798064.

thanks in advance.

Hi,

Thanks for the screen shot.

Well, it is quite possible that the problem might be with your code. So we appreciate if you could create a simple project, zip and post it here to show the issue. We will check it soon.

Thank you.

hi,

thanks for the reply.

we have testing instance and live instance of the application at two diffrent servers with same configuration and installations.

we are facing this issue on Live instance but on testing instance we are not facing this issue.

As this issue is happening any time, it is difficult to simulate it or create a dummy project or even supply our code to you.

you can see the error message in screen shot attached and suggest what could have caused this error.

you can call me at 9740798064 or if you can provide your contact no. i can give you a call to discuss in details.

thanks.

Hi,

Well, since your testing instance is working fine, so please make sure and compare its configuration or other settings/rights with live instance. If testing instance is working fine then live instance should also work fine.

Well, there might be many scenarios regarding NullReferenceException, so I am afraid are not very sure checking the stack trace. Kindly create a sample test project to simulate the issue, we will figure it out then.

Thank you.

hi,

i am afraid i will not be able to simulate the issue, since i dont know why the error is occuring.

if i know the possible reason then i can think of possible remidy.

we are getting this error in the part where we use the export to excel functionality.

we click on the tab and this error is thrown.

to rectify this error we do the following steps:

1. delete all the temporary .NET files.

2. restart the IIS.

after these steps the application works fine. but we want a permenant fix to the problem since it is a live site.

please help. 

hi,

to give an insight to the error, if we see the stack trace we get an error at aspose.cells level and the application is not able to find the refrenced lisence object.

we have given the aspose lisence file as an embedded object while deploying the code.

please find below the way we have passed the lisence file in the code.

we deploy the dll of the EITBF project on the server. which has lisence file as an embedded object.

thanks.

Hi,

Please make sure that when you deploy the project, the .lic file should be there in the project folder or you may manually copy the license file there in the project on the server. Also, I think you may try to explicitly set the license file path in your code (instead of embedded object) if it works fine.

Thank you.
