<p>Windows Mobile pops up a "busy wheel" - a rotating colour disk - when things are happening .  I can't find in the documentation how this is done - can someone point me in the right direction?</p>

<p>We have a situation where we need to prompt the user to say we're doing stuff for a while, but we don't know how long it will take. So we can't do a progress bar, hence the proposal to use this busy wheel.</p>

I'm just guessing here, but I'd imagine it is
CWaitCursor
.  Basically, you just create one on the stack, it appears, and disapppears when it is destructed as it goes out of scope e.g.
```
```
void DoSomethingSlow()
{
  CWaitCursor cw;
.
.
.
.
}
```
```
