how to lock the keyboard

[senthilkbs]

ie. when my application is started, the keyboard must be locked, such that the user is allowed to use only the mouse, when my application is unloaded, the usual setting must be retained(ie. the keyboard must work),

how to proceed,

any suggestion, samples appreciated

thanx in advance

do you want the keyboard to work in other applications that are running in other programs when yours is running, or just block the keyboard completely.

I don't think there is an easy way of blocking the keyboard entirely across the system, you can block the mouse and keyboard together using the BlockInput API (NT/2000 upwards only).

For keyboard blocking on just your app you could ignore any keyboard input (set the forms keypreview to false and set the keys to 0 in the form_keypress event)

possibly for both use(ie, for my app. and whole keyboadr),

but still i will try ur suggestion.

ur link is not working, pls check ur link

\\%winbootdir%\system\rundll32.exe keyboard,disable


if the above is not an url link, i think it is the syntax to be used in the system, so the above syntax is for disabling the for enabling the keyboard, can i replace disable to enable

thanx
