Keboard Hook Dll problem urgent

I have done a keyboard hook and in my callback function i have to check for
each character

if (wParam >= VK_NUMPAD0 && wParam <= VK_NUMPAD9)
then it is checking correctly for numeric keypad nos

but if i want to check for

if (wParam ==VK_A)
then it is giving an error
undeclared indentifier vk_A
but i havent declared for vk_numpad0 but it is working
i appreciate somebody can write a funciton like

switch (wParam)
                              {
case VK_1:
      MessageBox(NULL, "VK_1", "testing", MB_OK ) ;
      break;
case VK_2:
      MessageBox(NULL, "VK_2", "testing", MB_OK ) ;
      break;
case VK_3:
      MessageBox(NULL, "VK_3", "testing", MB_OK ) ;
      break;

where i can pop up the message while testing the application.

Thanks in advance

From Winuser.h:

VK_0 - VK_9 are the same as ASCII '0' - '9' (0x30 - 0x39)
0x40 : unassigned
VK_A - VK_Z are the same as ASCII 'A' - 'Z' (0x41 - 0x5A)

So, instead of VK_1 use '1' etc.

It is like this

 If (Wparm= 'A')
{do some process}
else  if (Wparm= 'B')
{do some process}

It is not 100% correct to write "I found the same answer" 20 hours after getting the answer in EE. I have no objections but I hope this is not your usual way to ask questions.
