Hello,

code:
so when i click to take a snapshot ..
nothing happenes,no crahsed , and no lagging ( as some people experienced with 9.8.0 and other DLLs) . when i researched the subject , i found out that some people got the file to be generated without images ( in C++) and others had exceptions and crahses ( also in C++) but i have not found anyone who got this feature to work in C#. The function looks simple but doesnt work for me . Does it have to do with the arg string ? do i ned to enable the snapshot feature ?
my args are:
Thank you
