It looks as if you are trying to lock the keyboard, you need to give a bit more information on what you are trying to do.
Have you written any code?

keybd_event Function

i am thankfull that somebody reply on my thread...

honesty... im still study right now asm... in online tutorials.. and still gathering information..

pertaining to my question... i tried "keybd_event Function" but still it doesnt work...

i am making a program from asm to send a key throu press button event... similiar to OSK.exe but i need to
customize it for may conformity...

thanks again...

You'll have to show us your code so we can help you with that - otherwise we don't know why it doesn't work :wink

thanks for the reply Tedd.

im still a beginner, actually i dont know how to make one except hello world.. im still study...

on other hand, is there away to make it readable asm files...?? because i only know VB programming...

Maybe it is a program like the On-screen keyboard in Win XP ?

When used along with a text editor, set the focus to the editor,
then clicking on the screen keys will send keys to the editor.

Prefered method is using an ACCELERATORS table

Further steps are needed

in the rc file

      // Accelerators table   54 et 55 are numbers of command
      // ctrl+space shift+insert
      SDIDEMO ACCELERATORS DISCARDABLE
      BEGIN
      VK_SPACE,54, VIRTKEY, CONTROL, NOINVERT
      VK_INSERT,55,VIRTKEY, SHIFT, NOINVERT
      END

at the beginning of the source code,you need to load this resource

      invoke LoadAccelerators,hInstance,SADR("SDIDEMO")
      mov Haccel,eax
              ;in the WM_COMMAND message
      .elseif eax == 54
      ;do something

Finally,you must insert a piece of code in the messages loop

      @@:
      INVOKE GetMessage, addr msg,0, 0, 0
      .if eax != 0 && eax != INVALID_HANDLE_VALUE ;WM_QUIT ou crash
      invoke TranslateAccelerator,hWnd,Haccel, ADDR msg;keyboard events en WM_COMMAND
      INVOKE TranslateMessage, addr msg ;get the message
      INVOKE DispatchMessageA , addr msg ;send les messages aux fenêtres
      jmp @B
      .endif

You must modify this pieces of code with your own name of variables ,see winhelp or better the SDK for this
