In LV7.1 how can I use a command from a .Net .DLL file that requires an input from .NET class TimeSpan?

[JasonHamilton]

I am currently using LabView 7.1 to control an instrument using a .NET 2.0 compatible API.  A dispense command requires that I set the dispense timeout.  The command is expecting a standard .Net class but when I create a constant I just get a dog eared piece of paper that says .NET.  I cannot see a way to set this value.  How can I send the proper value to this command?

Hello Jason

The timestan is inside the mscorlib.dll, in order to use it you have to create a contructor node and select the mscorlib as show in the image this will create the reference you need:

to locate the timestan  open +system and search for it, then you just have to create a .net property or invoke node to access the properties or the methods of the timestan object:

Thank you very much.  Once I finally found the correct version of the file everything seems to work great!
