If all the windows are actually Delphi forms, the following code will do it :

For i := 0 to (Screen.FormCount - 1) do
  SendMessage(Screen.Forms[i].Handle, ......)

Note that you can use Screen.Forms[i].Perform(...) instead of SendMessage, this will be more efficient.

To send a message to the child windows of the forms as well, use
  Screen.Forms[i].Broadcast(...) instead.

To send a message to *all* windows of an application, including those not created as forms ar as controls in forms, you will need to use the API function EnumWindows.
