Here is the correct code:
Private Declare Function mciSendString Lib "winmm.dll" Alias
"mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As
String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
'to close it:
retvalue = mcisendstring("set CDAudio door closed", returnstring, 127, 0)
'to open it:
retvalue = mcisendstring("set CDAudio door open", returnstring, 127, 0)
This works...

TO PUT API COMMANDS INTO VB YOU MUST*:
Click Project Menu, select Add Module
Select Module in window that pops up.
Paste the API code right into the Module.
*This is how you do it in VB5 Ent

This code seems to work:
close it:
retvalue = mcisendstring("set CDAudio door closed", returnstring, 127, 0)
'to open it:
retvalue = mcisendstring("set
CDAudio door open", returnstring, 127,
0)
