>I have an excluded FXP called from my EXE. VFP prompted dialog box to find 'myform.vcx' when my code try to CREATEOBJECT('myCusDataForm'). I have checked the loaded classlib using SET('CLASSLIB') and myform.vcx with alias myform has been loaded into memory.

An excluded component is external to EXE and cannot see Forms, Classes, Reports, e.t.c. in EXE. You may try to use NEWOBJECT() with 3rd parameter or SET CLASSLIB TO ClassLibraryName IN EXEFileName.
