CFileDialog in Threads

I need to get handle of modal file dialog box. for that I am putting
CFileDialog in thread. I am creating 2 threads . In one thread i am
invoking CFileDialog and in another thread I am trying to get handle of
that dialog box using GetForegroundWindow().....but with code given
below I am not getting handle of file dialog box but getting my
CTestDlg dialog box handle.....


void CTestDlg::OnOK()
{
	// TODO: Add extra validation here
	CWinThread* pWThread1 = AfxBeginThread(Thread1, this);

	CWinThread* pWThread2 = AfxBeginThread(Thread2, this);
                .......
                .......
}

UINT Thread1(LPVOID pParam)
{
static char szFilter[] = "COFF files (*.txt)|*.out|All Files
(*.*)|*.*||";
CFileDialog fileDlg(TRUE, NULL, NULL, OFN_HIDEREADONLY |
OFN_OVERWRITEPROMPT, szFilter);
fileDlg.DoModal();
return 1;
}

UINT Thread2(LPVOID pParam)
{
	::SetWindowText(::GetForegroundWindow(),"Save Text File");
	 return 1;
}

**BUT... WHEN I CHANGE Thread2() FUNCTION LIKE BELOW I AM GETTING
HANDLE OF FILE DIALOG BOX AND ITS PROPERLY SETTING WINDOW TEXT...LIKE
THIS..

UINT Thread2(LPVOID pParam)
{
                 Sleep(100);
	::SetWindowText(::GetForegroundWindow(),"Save Text File");
	 return 1;
}

but I think using Sleep() is not perfect way for doing this...because
100 factor for Sleep function is not fixed for every time...I am new to
thread programming. .. so I want to know which is other way to getting
handle of file dialog box... how can i know that my modal file dialog
box is become foreground window.....

Thanx in Advance
