MFC Dialog: How to add a minimize/maximize button into your dialog?

Q: How to add a minimize/maximize button into your dialog?

A:

• At design time: use the dialogs properties in the resource editor.
• At runtime: override the 'OnCreate()' function like this:

Code:

---

int CYourDialog::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  if(CDialog::OnCreate(lpCreateStruct) == -1)
    return -1;

  // TODO: Add your specialized creation code here
  SetWindowLong(this->m_hWnd,
                GWL_STYLE,
                GetWindowLong(this->m_hWnd, GWL_STYLE) | WS_MINIMIZEBOX | WS_MAXIMIZEBOX);

  return 0;
}
