I'm working on a script that does lengthy instructions on first run (sets up an encryption scheme and everything). Right now I'm trying to use a progress bar in Marquee mode to show the user the script is still working, but... starting the animation on the bar gets tricky.

Control:

code:

---

<Control xsi:type="ProgressControl" Id="ProgressBar">
    <Position Top="92" Width="280" Left="23" Height="15"/>
    <Marquee/>
</Control>

---

Code (After window creation):

code:

---

var WM_USER = 0x400;
var PBM_SETMARQUEE = WM_USER + 10;

var api_response = WizardWindow.SendControlMessage("ProgressBar", PBM_SETMARQUEE, 1, 250);

---

api_response always returns 1, indicating that the animation should be working,  but it doesn't. Any ideas?
