It seems like you have a couple different questions going on.

1.  You can go to VI properties and disable the scrollbars so that the user can shift the front panel around.

2.  I don't understand what you are saying by "my subVI should be accommodate with [sic] in the main VI window"

i have an main vi, its maximize with the size of monitor. when i call the sub vi it will open on the main vi.. and the subvi windows property sets as floating,

my question is,

                           lets consider the microsoft VC++ IDE there you can find there if you create a form, you cannot move out of the main window... like this i need, also i want to show the like property window and its also should not move.

You could simply use a subpanel. Examples ship with LabVIEW showing how subpanels work.
