show a message box without waiting for any user-action

[Andreas Richter]

I want to display a message box during the program does a time-intensive action. If I use the MessageBox() - function or if i use a resource constructed box with the DModal() - function, the program stops and waits for a user action.


What kind of function can I use to get this:


{

program shows a message-box <-- ?????


program does some action, message-box is displayed


program clears message box <-- ?????

}
