What is the reason for you to use scenario #2? What DLL are you calling?

 And how?

What are the exact input values in scenario #1?

for the scenario 2 ,i just try another method to have a solution with no error, i search in digital.ni.com 'how to copy a file" and i find this method.

for the scenario 1,i will send the code,but it will not run because it need to load another vi

Did you look at the Help for the Copy File function? It has an "overwrite" input.

Note: Your code uses the Current VI Path function. Be careful with this function. Why Does My Executable Not Work When Using the Current VI's Path Constant?

omg it's ok, a  true constant o the overwrite solve my problem

thanks to all
