Annoying beep when tab key pressed in basic windows app

Annoying beep when tab key pressed in basic windows app

I'm trying to get rid of the beep whenever I press the TAB key in the
windows app below ...
#include <windows.h>
//global vars ...

HWND hPanel;

HWND hRadio2;
HWND hRadio3;
const int panelWidth = 200;

lParam)
{
int clientheight;
switch (uMsg)
{
case WM_SIZE:
clientheight = HIWORD(lParam);
SetWindowPos(hPanel, NULL, 0,
0, panelWidth, clientheight, SWP_NOACTIVATE | SWP_NOZORDER);
return 0;
case WM_CLOSE:
DestroyWindow(hWnd);
return 0;
case WM_DESTROY:

return 0;

return DefWindowProc (hWnd, uMsg, wParam, lParam);
default: return DefWindowProc (hWnd, uMsg, wParam, lParam);
}
}

Any help greatly appreciated. (If I remove TranslateAccelerator() the
beeping disappears.)
