Command Line Parameters
You will have noticed that so far your program does not open the file. Explorer passes the file path to your program when it starts, and you can access this through the Command$ function.
Private Sub Form_Load()
'// check command line argument:
If Command$ <> Empty Then
'// we have a file to open
OpenFile Command$ '// call your
openfile procedure
End If
End Sub

The code is working fine, except for the OpenFile bit.
The comment says to call your openfile procedure.
What is the OpenFile command?
In using implimens this process into an application, I noticed the following line:
ret = RegSetValue&(lphKey, "shellopencommand", REGSZ, sKeyValue, MAXPATH)
did not properly register the association. I am using Windows 98 and had to change the above line to:
ret = RegSetValue&(lphKey, "shell\open\command", REGSZ, sKeyValue, MAXPATH)
to get it to work properly.
