Need help on Docking Rollout

edit: reposted in correct reply thread

This works:

try 
(
    cui.UnRegisterDialogBar TestDialog
    destroyDialog TestDialog
) catch ()

rollout TestDialog "Title"
(
	local theDockState
    local DialogDock
    local scriptpath = @"D:\"
    local INIfile = scriptpath + "Settings.ini"
    button btn "Button"
    
    function dockstatus = 
	(
        DialogDock = getINISetting INIfile "Dialog" "Dock"
        TestDock = case DialogDock of 
		(
            ("cui_dock_left"): #cui_dock_left
            ("cui_dock_right"): #cui_dock_right
            ("cui_dock_bottom"): #cui_dock_bottom
            ("cui_dock_top"): #cui_dock_top
            ("cui_floatable"): #cui_floatable
        )
		format "TestDock: % \n" TestDock
        TestDock
    )
    
    on TestDialog open do 
	(
        format "Open %\n" (dockstatus())
        cui.RegisterDialogBar TestDialog  maxsize:[-1,-1] style:#(#cui_dock_all, #cui_floatable, #cui_handles  )
        cui.DockDialogBar TestDialog (dockstatus())
    )
    on btn pressed do		
	(
		theDockState = (cui.getDockState TestDialog)		
        cui.UnRegisterDialogBar TestDialog
        destroyDialog TestDialog
    )
    on TestDialog close do 
	(
		setINISetting INIfile "Dialog" "Dock" theDockState forceUTF16:false
    )
)
createdialog TestDialog width:275 height:74 style:#()

thanks for the response :)

so i try it and It is working perfectly, it seems the problem was on dialog moved?

but if i run the script again while the one before is not closed yet using the button.
it create some uncloseable rollout instead

if possible i will remove that button on the final version of my script and using the standard close button
but again if you press the red close button it says error

-- Error occurred in TestDialog.close(); filename: ; position: 1208; line: 46
--  Frame:
>> MAXScript Rollout Handler Exception:
-- Unable to convert: undefined to type: String <<

position: 1208; line: 46 is >> setINISetting INIfile "Dialog" "Dock" theDockState forceUTF16:false
it seems that theDockState become undefined.

is the error just on mine?
is it posible to create dialogbar without those titlebar and close button on float?

When I use the code bellow I have no error. Executing the code while the rollout is docked leads to creating the same rollout, docked at the same position.

try 
(
    cui.UnRegisterDialogBar TestDialog
    destroyDialog TestDialog
) catch ()
 
rollout TestDialog "Title"
(
	local theDockState
    local DialogDock
    local scriptpath = @"D:\"
    local INIfile = scriptpath + "Settings.ini"
    button btn "Button"
 
    function dockstatus = 
	(
        DialogDock = getINISetting INIfile "Dialog" "Dock"
        TestDock = case DialogDock of 
		(
            ("cui_dock_left"): #cui_dock_left
            ("cui_dock_right"): #cui_dock_right
            ("cui_dock_bottom"): #cui_dock_bottom
            ("cui_dock_top"): #cui_dock_top
            ("cui_floatable"): #cui_floatable
        )
		format "TestDock: % \n" TestDock
        TestDock
    )
 
    on TestDialog open do 
	(
        format "Open %\n" (dockstatus())
        cui.RegisterDialogBar TestDialog  maxsize:[-1,-1] style:#(#cui_dock_all, #cui_floatable, #cui_handles  )
        cui.DockDialogBar TestDialog (dockstatus())
    )
    on btn pressed do		
	(
		theDockState = (cui.getDockState TestDialog)		
        cui.UnRegisterDialogBar TestDialog
        destroyDialog TestDialog
    )
    on TestDialog close do 
	(
		try(setINISetting INIfile "Dialog" "Dock" theDockState forceUTF16:false)catch()
    )
)
createdialog TestDialog width:275 height:74 style:#()

On mine Executing the code while the rollout is docked leads to creating the same rollout docked at saved ini position.
Well at least it work Thank you very much :)
also it seems that max didn't really save the exact position of the dock, is there any work around for that?

IF you have several docked toolbars/rollouts 3dsMax do not saves their position. Wneh you undock one of those toolbars/rollouts and dock it again it will be docked to different position. I don't know a way to fix this using a script.

By the way you can add a RC Menu to allows the user to dock/undock the rollout. Please, watch this video:

that surely is an interesting suggestion, thank you :)

You can use something like this:

try(cui.UnRegisterDialogBar rol_dockTest)catch()
try(destroyDialog rol_dockTest)catch()
rollout rol_dockTest "SUN SYSTEM"
(
	button btn_dockLeft "Dock Left" pos:[0,4] width:60 height:20
	button btn_undock "Undock" pos:[60,4] width:60 height:20
	button btn_dockRught "Dock Right" pos:[120,4] width:60 height:20
	
	on btn_undock pressed do
	( 
		cui.FloatDialogBar rol_dockTest 
	)
	on btn_dockLeft pressed do
	(
		cui.DockDialogBar rol_dockTest #cui_dock_left
	)
	on btn_dockRught pressed do
	(
		cui.DockDialogBar rol_dockTest #cui_dock_right 
	)
)
createdialog rol_dockTest 180 100
cui.RegisterDialogBar rol_dockTest

i found similar problem in this closed thread:

it seems that there still isn't any solution for that
i think i might give up on docking rollout and let it be on float. 🙁
