How to change timeout for generic iviScope functions using SetAttribute?

[OnlyOne]

Hello,

i am using the generic functions of the iviScope.

Now i need to change the default timeout value.

For this i wanted to use the function IviScope_SetAttributeViInt32 with the Attribute VI_ATTR_TMO_VALUE.

But when executing the function returns "Attribute not recogniced".

So how can i change the timeout if not with this attribute?

I am using the "niScope" driver for the driver-session.

Thanks for help
