hello,
            sorry i forget to add one vi....this
sub.vi set as a child window and main as a parent window using user32.dl
now try
this, just check.... 
1.
click on the child vi button
2.
sub.vi will open
3. just
click on the graph, now check when you do each click the sub.vi will move down
below.
open
the sub.vi, where you will find set parent and child.vi,  make disable that using disable structure
4. run
the main.vi
5.
click the child vi button
6.
subvi will open and click on the graph using mouse, when you do each click on
the graph the vi  will not move down below.
As per
my task, I want to keep my main.vi as a parent and all subvi’s as a child.( Not
as a subvi), also when I click on the graph the vi should not move down below.
On my
project I am  calling vi as dynamically
only….this is for example vi which I sent you.
Help me..!
