Hm ,I saw this in the VB 6 Forum as well!

For which one do you want it ¿

Please don't post the same post in different forums.

i Just require the methodology so that i can handle it im my code,

It's set into registry key in HKEY_CURRENT_USER\Control Panel\Desktop in value named "UserPreferencesMask" , the detailed description is available here, see the Bit 5's description, it's for Keyboard cues.

Usually such settings are stored in registry, if you use regmon to watch registry changes done by rundll32.exe (this exe launches the disply properties) then you can easily find out which key,values are used.

Thanks Krishna,
I've tried this, but it requires a login again, only then its getting reflected. is there any other way to do that?Thanks in advance.
