Hello sir. I am a student of National University of Science and Technology 
undergraduate program. I am working on RECORDING THE ENERGY TRANSFERS IN A DROP 
HAMMER VIA VELOCITY SQUARE AND FORCE VELOCITY METHODS.  I am using NATIONAL 
INSTRUMENTS NI cDAQ 9172 as a data logger and using Visual Studio C sharp as an 
interface for recording data and measurement studio 2015 modules. sir i have 
attached 2 strain transducers and 2 piezoresistive acclerometers. i am getting 
the error when i try to execute my program. i am sending you the complete 
program. error is "Resource requested by this task has already been reserved by 
a different task."  sir please help me regarding this issue as i have very less 
time left for my final year project and already have spent good about 7 months 
working on the codings.  i shall be really obliged for your kind help as in my 
country there is no one qualified to handle measurement studio programming. 
Your company's equipment is used and only NIMAX is used by majority of the 
people or atmost LABVIEW modules provided by you. Please look into my matter 
with your kind keen interest.  Thanks Alot Sir.
