Check files without certification information

[Jin]

if the file does not have Certification information, The returned aqFileCertificateInfo will be one with empty string value. Error will be occured when someone try to check property.

How can I know its a file without certification information before I try to do more checks?

I would check to see if the variable used for the cert info is not empty.  If that is true, then do the rest of the checks.

But how... As I said... There will be one aqFileCertificateInfo Object (empty value) returned back... If I want to check its properties.. broken with error

This uses the file in the example from here

Hi Marscha, 

Thanks for your feedback... however I know this Weblink and I have to highlighten one sentence in there 

.... If you try to call properties or methods on such a certificate from your tests, an error will occur.......

Means I got an "empty" CertInfo back in case of that the file does not have any digital signature. 

My question is how can I know its an "empty" CertInfo before I do any checks on its properties....

What happened when you tried my example?  Show the log please.

I did similar things but using script: 

My code like 

var certinf0 = aqFileSystem.GetFielInfo(file).CertificateInfo; 

then I try to do some comparison like 

aqObject.CompareProperty(certinfo.Subject, cmpContains, "some signature", true, 0);

Error occured:

It would be helpful if you try the exact example that I gave you.  It is from the documentation and if it does not work for you then it gives us a path to follow.
