Feeze Posted March 10, 2018 Share Posted March 10, 2018 Hi, im new there and trying to learn how autoit works. I have files that contains some data (hex) i want to one-click replace , looks like: FF F0 0F FF F0 0F 06 00 06 00 AE 08 2A 1A 5A 2B FC 33 00 00 00 00 00 00 00 00 B8 4D 45 00 FF FF C8 00 00 FF 96 00 00 FF 96 00 00 FF 00 00 00 FF 00 00 00 FF FF FF FF FF 00 00 00 FF 00 00 00 00 EF E0 1F D8 D7 28 FF F0 0F FF F0 0F CC C3 3C 41 script must replace string from 0x24 till 0x2F ( 960000FF960000FF000000FF ) with FFF00FFFF00FFFF00FFFF00F. each file have different data, before and after mentioned adresses , there is no rows etc. so editing possible only by offset. Ive been trying to use FileOpen but it erases data before setted position or after $FO_APPEND (1) = Write mode (append to end of file) $FO_OVERWRITE (2) = Write mode (erase previous contents) help please Link to comment Share on other sites More sharing options...
BrewManNH Posted March 10, 2018 Share Posted March 10, 2018 Did you try the FileOpen with the Binary option? Quote $FO_BINARY (16) = Force binary mode (See Remarks). If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.
