Unload effect

Is there anyway to brake up my form into 8 pieces and each piece will fly into different direction

No.

Yes!

In theory you could do something like :

1. Have a single form, eg frmUnload
2. When you unload your main form -

- create 8 instances of frmUnload
- bitBlt the captured image of your main form and 'dissect' it into
8 sections
- bitBlt the sections into each frmUnload's HDC
- hide your main form
- move the frmUnload instances around how you like
- unload all of them

Here's example code for 4 pieces. Assumes main form is 'Form1', another form named 'f1'. f1 has no caption, no border, no control box, autoredraw=true. Put the following code into a module and call it.
