Is there any way to emulate INKEY$ in Visual Basic? I'm pretty sure there is some API in Windows that will let me. I can't use the form keypress events, because I'm emulating the DOS console as well (with the console API).

Public Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState" (ByVal vKey As Long) As Integer

Yes... but doesn't that only react to a specific key?

Because what I'm looking for is a way to simulate a C-style getch() or getche().

oh... i thought you're looking to capture the key pressed. sorry!

with asynckeystate you can loop thru all the keys to see if any of those is pressed (that is what keyloggers do, and is pretty fast)

You could use the GetKeyboardState() API  http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/UserInput/KeyboardInput/KeyboardInputReference/KeyboardInputFunctions/GetKeyboardState.asp in combination with fozylet's
 GetAsyncKeyState() API to determine if a key has been pressed.  You would have to poll however.

Also, take a look at this article http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q177/9/92.asp&NoWebContent=1
as it may be of help to you as well.  But be sure to read those notes at the very bottom though.
