CODE


I have two dialog boxes in my application. Buttion click on first dilaog will display the second dialog box.

void CBranchRegionDBDlg::OnBnClickedOk()
{
    // TODO: Add your control notification handler code here
    CLBRegionDlg dlg;
    CDialog::ShowWindow(FALSE);
    dlg.DoModal();

}

in the dialog box, there is buttion lcik function, assinging a string value to the edit box member varibale of type CString,  after that I am calling UpdateData(false) to populate the data into the edit box.

void CLBRegionDlg::OnBnClickedOk()
{

  
    m_szStatus = "hello world";  
    UpdateData(FALSE);

}

but UpdateData(FALSE) throwing an error

[b]Debug Assertion failed![/b]

Pointing to the following line in wincore.cpp
        CHandleMap* pMap = afxMapHWND();
        ASSERT(pMap != NULL); // error points here.



I need help in this. I am using Visual Studio 2008

Basically its saying that the pointer handle is NULL, that's why it failed the assertion.
