After importing FabTools you have the following errors :

1) Method FABREGISTRY:_GETKEYINFO
Line 22, missing '}' in object creator FABREGKEYINFO{}:51419

2)Method FABSTANDARDFILEDIALOG:FABDISPATCH
Line 12, negative value not allowed:51178
Line 28, negative value not allowed:51178

 

For the first question, as far as I remember, this is a typo that the 27b compiler doesn't accept: there is a ) instead of a }, just correct this

For the second one, you should have :

       IF ( NMHDR._code == CDN_INITDONE ) 

simply replace it with

       IF ( NMHDR._code == DWORD(_CAST,CDN_INITDONE) ) 

this should do the trick.
