Just FYI, it might be more helpful if you would provide a project archive instead of expecting people to copy and paste.

Where is the documentation for libqrencode to be found?

Why is "As Integer" in "Private Extern QRcode_free(qrcode As Pointer) 'As Integer" commented out?

You create a new structure with "Dim stQr As New QRcode", then set it to Null, then assign the pointer returned from the Extern 
function to it. Why? If the QRcode_encodeString function returns a struct, then you should probably do:
Private Extern QRcode_encodeString(sText As String, iVersion As Integer, iLevel As Integer, iHint As Integer, iCasesensitive As 
Integer) As QRcode

It has been a while since I worked with an external library function that returns a pointer to a struct, so I welcome being 
corrected on that.
