The no arguments passed into the Create() function of a modeless dialog box are two. The first one is an unsigned integer, representing the ID value of the dialog box. The second argument is a pointer to the parent window.
Here is an example which displays a modeless dialog box:

CMyDiaog *m_pdlg=new CMyDialog;
m_pdlg->Create(IDD_MYDIALOG,this);

When you are using the Create method, it is recommended to create it on the heap. However, using other methods, you can still create modeless dialog boxes without using a pointer.
Thanks

You must also override CDialog::PostNcDestroy()

void CMyDialog::PostNcDestroy()
{
  delete this;
}

so you dont need to explicitly delete m_pdlg
