Problems with license code

The issue we are having is that after creating the license object, we are unable to use the SetLicense method to actually register the license with the software. The error we recieve is that the variable name for the license object needs to be declared.

Please share your code that you are using the set the license file. I have already sent your license files to the developers so they can look over them. Here is how you are supposed to set it: The developer will help you shortly.

Dear glixa,

Thanks for considering Aspose.Slides for .NET.

I have checked your license file for Aspose.Slides and there is no problem with it. It seems there is some coding problem, probably you are not declaring license object.

Since, you have two license files for two products; so you need to set both of them separately. Every product has its own license class e.g




It means, for using license of various products, you will have to use complete name of License class to avoid ambiguous names in different namespaces. e.g

So the proper way of setting license would be like this in C#

Aspose.Slides.License slidesLic=new Aspose.Slides.License();


Aspose.PDF.Kit.License pdfkitLic=new Aspose.PDF.Kit.License();


so on ..

One more thing, you must set the license before using any other product API.

For general programming information, please see products WIKI, for example, the Aspose.Slides.Wiki can be found at this link.

Other WIKI(s) can be located from this link.

I hope, it is helpful.

I have the following 4 lines of code in my file before any of the product API’s are used.

Dim license As New Aspose.Pdf.Kit.License()

Dim lic2 As New Aspose.Slides.License()

I get a “Declaration expected” for the two lines that are actually using the SetLicense method.

Dim lic2 As Aspose.Slides.License = New Aspose.Slides.License()

and similar for Aspose.Pdf.

I originally had the code like that, however after participating in a live chat with ‘AdeelTaseer’ I changed it to the code I previously posted. I’ve changed the code back to match the example you’ve given and I still get the error.

Please post your code here in the forum.

This is all I am able to post due to the sensitive nature of the rest of the code.

'* licensing Instructions - from the .xml lic file

Dim license As Aspose.Pdf.Kit.License = New Aspose.Pdf.Kit.License()

Dim lic2 As Aspose.Slides.License = New Aspose.Slides.License()

Protected Overrides Sub OnStart(ByVal args() As String)

'See notes in method

End Sub

Why licensing code written in the class declaration???
Move it to the OnStart method before any other code.

Not sure why the code was put there, I didn’t write it I’ve just been tasked with maintaining it. Thanks, though, that fixed the issue.
