how can I use getmessage to wait for a keypress
I don't know much about the return codes of getmessage and the like, how can I use it to wait for a key press?

Don't care if it ties up my app until i hit a key. Here's some code to play with..



  .while TRUE
 invoke GetMessage,addr msg,NULL,0,0
    .if ( eax )
      .if ( msg.message == WM_QUIT )
        mov bQuit, TRUE
      .else
        invoke TranslateMessage, addr msg
        invoke DispatchMessage, addr msg
      .endif
      .endif

Re: how can I use getmessage to wait for a keypress

WaitForKeyPress macro
@@:
	invoke GetMessage,addr msg,0,0,0
	cmp msg.message,WM_KEYDOWN
	je @F
	invoke TranslateMessage,addr msg
        invoke DispatchMessage, addr msg
	jmp @B
@@:
endm

Or if you want your @@ labels, use:


WaitForKeyPress macro
local again,done
  again:
	invoke GetMessage,addr msg,0,0,0
	cmp msg.message,WM_KEYDOWN
	je done
	invoke TranslateMessage,addr msg
        invoke DispatchMessage, addr msg
  jmp again
  done:
endm
