' dynform.bas -- Dynamic Form Demo
'
' Demonstrates building a complete form entirely in code
' with no .frm file needed:
'   CreateForm      - create a form programmatically
'   CreateControl   - add controls with optional parent
'   SetEvent        - bind events to arbitrary handlers
'   RemoveControl   - remove a control at runtime
'   Optional params - language extension for optional arguments
'
' Add commdlg.bas to your project, then click Run.
