C++ Polymorphism

[RogerThat123]

What affects will polymorphism have on my application? Can i use it so my program CRC changes each time on runtime?

I think I remember reading somewhere a long time ago about it but I forget.

What are you talking about? Is this a guessing game?

No. Those 2 things are totally unrelated. Polymorphism is a coding technique and the CRC of your program is just a calculation.

Alright, well I thought I read that a long time ago.

Anyways, sorry for the dumb thread.

But I am curious how one may change the crc of their program so each time you launch its different.

I know the crc is based on the file, some sort of calculation of it, but without recompiling and adding code, how can I change the crc in the pgram at launch time?

What are you doing ? The crc of your program is totally not relevant for running it. Also, if the data doesn't change the crc check will also not change.

I need the crc to change on each launch, ive seen it done before. I know the data needs to change, but I cant figure how without just recompiling it with adding some code..

But i definitely know its possible..

I have this feeling that you are thinking about polymorphic code in the context of a polymorphic virus.

[RogerThat123]

what, lol.

Im not a very good programmer, and Im most definetly not making a virus.

I need the crc to change because for my program which I sell, each copy must be unique to each customer. So I distribute 1 copy, and when they launch it the crc is changed.

[Igor Vartanov]

Why don't you put your customer name into your program? That would definitely change the ultimate exe's CRC.

[RogerThat123]

I know, but I mean without recompiling. Like I send off 1 copy to ALL, and then everyone who runs it it changes the CRC when they either start it or exit.
