Forums -> UltraMon™ SDK -> Image refresh garbled in IE on 5 monitors
Dave Ferguson   2003-10-02 03:48
I am launching 5 instance of Internet explorer with a web page for displaying a single image. Each IE instance is moved to a seperate montitor.

On a seperate control monitor I run a slide show which assigns new images to each of the monitors running
monitor1.IE.Document.getElementById("idata").src = imageArray[imageIdx].src;

If I immediately assign another image to another monitor then both images are garbled as the system IE instances attempt to draw them simultaneously.
monitor2.IE.Document.getElementById("idata").src = imageArray[imageIdx++].src;

The problem gets worse as I add more monitors.

The solution so far was to set a timer between assigning images so that the images load sequentially however, I would prefer that the all the images load at the same time.

Is this a OS, IE , Ultramon or video card problem? What's the fix?

Sounds like an IE or display driver problem.

Please test if you have the same problem when manually positioning the IE windows and then starting the slideshow.

Thank you for your quick reply.
You are correct it is an IE problem.
Running 5 apps at once is too much strain on available resources. Timers a kludgy. I'll look into using framesets.

The orginal reason for using seperate instances of IE is that I could get the HWnd via
m.IE = new ActiveXObject("InternetExplorer.Application");
and then use it to assign the window to a monitor.

I would really like to position each frame or window in an individual monitor. Can individual windows from withing an app even be moved to a separte monitor or is this just too bizarre?

If I use a frame based solution or call win= new Window("imagedisplay.htm") from a HTA window based how can I get the hwnd?

If you can give the new window a different caption, you could then assign it to an UltraMon window object using the Window::Find method.
