I rarely every needs this type of stuff but its worth knowing how to both create and use animated cursors.

I'm wondering why do you preserve ebx in MsgLoop? :wink  Should be:

Code Select Expand


MsgLoop proc
    LOCAL msg:MSG
;    push ebx
    lea ebx, msg
;    jmp getmsg
msgloop:
    invoke TranslateMessage, ebx
    invoke DispatchMessage,  ebx
;getmsg:
    invoke GetMessage,ebx,0,0,0
    test eax, eax
    jnz msgloop
;    pop ebx
    ret

Lingo,

EBX is specified in the Intel ABI as needing to be preserved.

This would be the preferred code form if it in fact mattered. I have seen problems in the past with not calling GetMessage() before the other two calls so I ensure it runs first.

Code Select Expand


MsgLoop proc

    LOCAL msg:MSG

    push ebx
    lea ebx, msg
    invoke GetMessage,ebx,0,0,0

  msgloop:
    invoke TranslateMessage, ebx
    invoke DispatchMessage,  ebx
    invoke GetMessage,ebx,0,0,0
    test eax, eax
    jnz msgloop

    pop ebx
    ret

MsgLoop endp

Only CALLBACK procs, specified by the MSDN, need preserving the EBX,ESI,EDI registers if you will modify them...but MsgLoop and Main are not  CALLBACK procs! :wink

Thanks Hutch.

The demo also works on XP Home Edition Sp2.
