thanks for reply,,,

 i have another problem,, if i call one vi and after running this vi, how to close called vi and come back to calling vi with refrence to the  called vi,,

thank you

In the VI properties of the second VI (ctrl-I), in the window appearance section, check the show front panel and close afterwards boxes.

In the application control palette, you can use the 'This VI' reference and wire it to an output from the VI to return it to the calling VI.
