Answer 1

WM_CHAR中：
if((GetKeyState(VK_CONTROL) & 0x8000) || (GetKeyState(VK_SHIFT) & 0x8000))

Answer 2

//可以：
case WM_KEYDOWN:
switch(wParam)
{
case 'A':
if(GetKeyState(VK_CONTROL) & 0x8000)
{
OutputDebugString("CONTROL a \n");
}
if(GetKeyState(VK_SHIFT) & 0x8000)
{
OutputDebugString("SHIFT a \n");
}
break;

Answer 4

WM_KEYDOWN:
 if(GetKeyState(VK_CONTROL) < 0 && GetKeyState(VK_SHIFT) < 0 && GetKeyState(_T('A')) < 0 && GetKeyState(_T('B')) < 0)
 {
  ...
}
 break;
