The form class contained in D:\Chapter3\Hello1.frm is not supported in VBE. The file can't be loaded
Ahhh... you are trying to load a form. Forms are difficult to translate from VB to VBE; a form is the interface to your VB program, whilst in VBE the interface is the application (Excel, Word, etc).
What you need to do is copy the event procedures behind the controls on the form, create your own form in Excel with the same controls on it (same names too) and then paste the event procedures into your Excel form. Sounds complicated... it could be, and it may not completely work!
