assuming that the button's id is indeed IDC_BUTTON and that you have
m_button attached to IDC_BUTTON like this

void CMy_ApplicationDlg::DoDataExchage(...)
{
    ....
    DDX_Control(pDX, IDC_BUTTON, m_button);
}

then all you really need to do is
BOOL CMy_ApplicationDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    m_button.SetWindowText("My new Text");

    return FALSE;
}

If this is not working for you then there is something wrong with the
button. Maybe you have set a flag that by mistake (like bitmap or owner
draw).

You should not have to call UpdateData, or UpdateWindow, or Invalidate or
anything of that nature (the window isn't even visible yet).

Hi,

I have added a Button control from the toolbars and have set the
"caption" of it to nothing.
Now i want to display a text "HELLO-ME" on the Button control from my
application.

I have tried a lot of options, but it is not diplying the text at all.

What i have done is this,

BOOL CMy_ApplicationDlg::OnInitDialog()
{
CDialog::OnInitDialog();

       m_button.SetFocus();
int id = m_button.GetDlgCtrlID();
SetDlgItemTextW(id,L"It's-Me");

                   (OR)

m_button.SetWindowTextW(L"HELLO-ME");

                    (OR)

(GetDlgItem(IDC_BUTTON))->SetWindowTextW(L"Hello-Wake");

UpdateData(FALSE);
return TRUE;
}

m_button --> A member variable pointing to the button control

what should i do now. Is it that the button should be painted or
refreshed , so that it can display.
