How to unlock the resource if it is locked with error code BFFF000FF

[aiheong]

Hi,

I am using NI Visa library (NI Visa version4.6.2) for my applicaiton which written in C#.

Sometimes, the program might catch below error by using the exception handling function that halted my program. 

At this point, the VISA Sessions are still open and locked.

NationalInstruments.VisaNS.VisaException: Specified type of lock cannot be obtained, or specified operation cannot be performed, because the resource is locked. VISA error code -1073807345 (0xBFFF000F), ErrorResourceLocked

So, is there a way for me to programmatically unlock or close all VISA sessions on my machine, without knowing the handles

to the sessions in advance?

Thanks,
