Lag when the system repaints the check boxes

[AlexZ]

Hi fellas.

I am using a dialog with check boxes that use a dll for some nice simulations. It works fine, but the system only repaints the check box once the dll is finished. So there is a little lag, since the user checks the box and the box is repainted by the system.

I have used WM_COMMAND and BN_CLICKED notification code, as usual.

I can fix that using:

if check box state changes -> global_variable=1

WM_TIMER
if global_variable
--- global_variable=0
--- use dll

I would like to use a more elegant method, so my question is:

Please, is there any kind of notification after the check box is repainted? How to use it? Any other ideas?

Thanks for any help. Regards.

Call the dll in another thread.
Then if want to wait, use opt waitmsg 1.

Function Dialog192

Code:

str dd=
;BEGIN DIALOG
;0 "" 0x90C80AC8 0x0 0 0 224 136 "Dialog"
;3 Button 0x54012003 0x0 8 8 48 10 "Check"

;2 Button 0x54030000 0x4 168 116 48 14 "Cancel"
;END DIALOG
;DIALOG EDITOR: "" 0x2040308 "*" "" "" ""

str controls = "3"
str c3Che
if(!ShowDialog(dd &sub.DlgProc &controls)) ret


#sub DlgProc

ret 1


#sub Thread
;call a dll function, for example
Sleep 3000
