1. Windows Binding
When I try to bind a windows program, using bindw, I get an .exe file.
When I click on the .exe file from within windows, I get a DOS box pop
up with a messages about "please wait..." or something similar.
After a while, it adds "OK".
You press enter, the DOS box goes away, but the program doesn't run.
Obviously I'm doing something stupid, but I don't know what.
Anyone?
Thanks,
Irv

Heh heh, sounds like that built in security feature Rob told
us about not long ago. If the bind program and the "ex.exe"
file are from different releases it does this (I believe).
It's supposed to keep people from tampering with your bound
executables but I'm not sure how it works.

That's right.
The cryptic message and the delay are supposed to
confuse hackers who might be trying to tamper with
your .exe file. Unfortunately, registered users who
installed 2.1 alpha or beta prior to March 29 of this
year may also see this message if they still have
any old alpha/beta files lying around.
Irv: I'll send you the 2.1 Official Release instructions again,
in case you need them.

Just out of curiosity, how does that work? Like, if a person were to
change one byte in the person's file, would it get picked up on? How?
When the file is bound, is a value set in the .exe somewhere, of say,
the total sum of all the values of the bytes, or something?
Sorry about all the questions, but I was looking into writing a security
feature like that in C.
Thanks,
Greg Phillips

Something like that.
I can't be too specific without reducing security.
Anyway, this is really overkill since a shrouded and scrambled
file will already be extremely hard to tamper with.

Would it be possible to change the message that appears when a file has been
tampered with?
-Mark.

Hey, I just discovered an additional (intentional?) security feature the "One
moment please...".
I looked at 2.0's bound files, and it appears that the interpreter is included,
then the string 'BIND' is put at the end, followed by the code.
In version 2.1, if you can find the delimiter string (it's probably best I don't
say what it is), you see the shrouded and scrambled source. If you try to add
different code after the string, you end up with the 'One moment please',
whereas if you tried to do the same in 2.0, a proper .exe would be made.
