A small Tool to that to charge the Checksumme of Files.
The slot "checksum" becomes from the function "MapFileAndCheckSumA" accounts and "calculated" by the code, whom I written have which almost spot-on the same power How "MapFileAndCheckSumA".

Download

almost, because with manchen DLL, EXE files (i think it concerns generally Ausführbare) discern itself both Checksummen, i'm I do not sure, but I think, if in the Header the EXE The Checksumme stored is (ought to usually) then is the Checksumme the Codes short to the Compile! d.h. MapFileAndCheckSum reads this worth out, is there no worth in the Header, accounts these function The Checksumme...Difference, because my function always The Checksumme the whole File accounts

How I understood have, is the Result nothing other, as Filesize+remainder, zB with of/ one 6 byte large File the first Word (means 1. & 2. byte) with the 2. Word (means 3. & 4. byte) summiert, is the Result larger or same 65535, then becomes this worth (65535) from the Result abgezogen, the remainder becomes the 3. Word add etc. to that Schluss becomes the Restergebnis The Size the File in byte add, the Result is then The Checksumme, The zurückgeliefert becomes.

EDIT:
who yet whom Source + EXE v.1.10 & v.1.11 has becomes check, that The Variable ber# not Disposed becomes, Have I at Umschrieben forget
