Enable the script, then go to the memory browser, in the top-half right-click and choose to go to an address, then type in "Instant" for the address and it should go to the code. Then disable the script.

You'll see what the original code there is.
Enable it to see what it changes to.

Which part of the instructions are you stuck on?

-OP-
If you're wondering how to use that code:
Open up the auto assembler (Ctrl + Alt + A or open Memory View, Tools -> Auto Assemble), and paste this inside it:

Well for basic stuff on AOBs and finding bytes and stuff...

But for flash stuff specifically I'm not sure what they do as I've never done it myself.

It looks like those entries are part of a table. The first part of the entry looks like an identifier string (maybe a title or something), the second part is the assembly that's run to activate the cheat, the third part is a description, the fourth is an activation message, and the fifth a confirmation button. Without the full script, it would be hard to figure out what exactly was being done with all of that information. I'd guess that it's a part of a trainer.

IMO it's easier to have a few scripts in the cheat table like the one I posted earlier. If you don't want the disable part, you can just have this:

is the first time I use it , I found the code in the swf file ... but the code in the cheat engine is different , why?

It's actually not different in those images, but it is different from the one you originally gave. The bytecode of that function is:
d0 30 5d ca 43 d0 66 ab 1e 46 ca 43 01 48
...and the bytecode you're searching for in the image is:
d0 30 5d ca 43 d0 66 ab 1e 46
The one you originally gave was:
d0 30 5d c1 43 d0 66 a6 1e 46

The number of bytes you're searching for doesn't actually matter at all, so long as it's unique. So, searching for that first AoB and searching for that second AoB is the same thing (so long as they're both unique and start in the same place).

If you're asking why the one you originally gave is different, the game probably had an update. To fix this, try searching for this AoB instead:
d0 30 5d ?? 43 d0 66 ?? 1e 46

The ?? are wildcards, meaning CE doesn't care what those bytes are. However, you'll have to make sure this AoB is unique. To do so:

Attach CE to whatever you're hacking
Set the "Writable" checkbox to grey (don't care if it's writable memory or not)
Set the "Value Type" to Array of byte
Search for d0 30 5d ?? 43 d0 66 ?? 1e 46
Make sure CE only finds 1 result

If CE finds more than 1 result, you can try adding more bytes to your search:
d0 30 5d ?? 43 d0 66 ?? 1e 46 ?? 43 01 48

If it still gives more than 1 result, you'll have to omit the wildcards and search for the bytes themselves.

db is a pseudo-instruction that directly writes bytes to memory.
When you execute that script in your image,
d0 30 5d ca 43 d0 66 ab 1e 46
...becomes:
d0 30 24 64 48 d0 66 ab 1e 46

As for the bytecode itself:
24 pushes the next byte onto the stack as a signed value.
64 is the value it's pushing (64 in hex = 100 in decimal).
48 returns the value on the stack and exits the current function.
