how to show char "\t" in eVC3

void CMyView::OnPaint()
{
CPaintDC dc(this);
HDC hdc;
TEXTMETRIC tm;
TCHAR szOut[256];
hdc = ::BeginPaint(m_hWnd, &ps);
GetTextMetrics (hdc, &tm);
int cxCurrent = tm.tmAveCharWidth;
int cyCurrent = tm.tmHeight + tm.tmExternalLeading;
>> lstrcpy(szOut, L"Test\tTestTest");
ExtTextOut(hdc, cxCurrent, cyCurrent, 0, NULL,
szOut, lstrlen (szOut), NULL);
>> lstrcpy(szOut, L"Test\t TestTest");
ExtTextOut(hdc, cxCurrent, cyCurrent*2, 0, NULL,
szOut, lstrlen (szOut), NULL);
::EndPaint(m_hWnd, &ps);
}

Result:
Test[a hollow pane]TestTest
Test[a hollow pane] TestTest

why the char "\t" cannot be shown in eVC SDI's doc view?
any tip or suggestion would of great help.

What do you expect to see? The \t is replaced with a number which is the
character number for a tab. You certainly will not see

Test\t TestTest

Oh, ignore that. I misread the question and not enough coffee yet.

I implement the function TabbedTextOut() under eVC++3.
But I don't think it is enough good.
Any suggestion or tip would of great help.
