The "normal" way to do it is this:
1.
Write your program, which includes your checksum algorithm.
2.
Put in a constant string of a known length. This string must have an unique identifier (which can later be found, browsing through the exe file).
I.e. "____xyz____zyx____AAAA".
(This string is 22 bytes long + the null, making it 23.)
The "AAAA"-part is later gonna be replaced with the real checksum code (assuming that the checksum will be 4 bytes long).

3.
Write the check code (still in your program), working like this:
Open the exe file, read through it and calculate the checksum, but DON'T count the constant string! Instead, when the string is found, read the "AAAA"-part and interpret it as an integer (likely an unsigned int, depending on the checksum algorithm). Close the exe-file.

4.
Compare the calculated checksum with the checksum from the "AAAA"-part. If a match, the it is OK.


5.
Write another program, a;) checksum generator (re-use the code in step 3), but this time, when the ID is found, save the file offset to the "AAAA"-part. (Remember, don't count the ID-string!)
When the checksum is calculated, seek to the saved offset to the "AAAA"-part, convert the checksum to a string, and write it to the exe-file.

Of course, you must recalculate the checksum every time you compile your program.

Good luck.
