Mike,
Thanks for the reply and the idea on how to do it. I think
I am intimidated by not being familiar with Jscript. I will be doing some
study on Jscript in my spare time.
Ok, I tried your code and got a run time error , but modified it
to its simplest elements and have the simple version working. Thanks!
Here is what I had in exportimage1.js which I cut and pasted
from your post. This version gave me a run time error and complained
about filename.
AB = new ActiveXObject("Broker.Application");
Win = AB.ActiveWindow;
// e.g. Image_2008-8-6_14-22-33.png
rightNow = new Date();
fileName = "Image1_" + rightNow.getFullYear() +
"-" +
(rightNow.getMonth() + 1) + "-" + rightNow.getDate() +
"_" +
rightNow.getHours() + "-" + rightNow.getMinutes() +
rightNow.getSeconds() + ".png";
Win.ExportImage( filename, 1280, 960 );
Next I tried your alternative, which was exportimage3.js;
AB = new ActiveXObject("Broker.Application");
Win = AB.ActiveWindow;
// e.g. Image_2008-8-6_14-22-33.png
rightNow = new Date();
//fileName = "Image_" + rightNow.getFullYear() +
"-" +
//(rightNow.getMonth() + 1) + "-" + rightNow.getDate()
//+ //"_" +
//rightNow.getHours() + "-" + rightNow.getMinutes() +
//rightNow.getSeconds() + ".png";
filename = "Image3_" + rightNow.getTime +
".png";
Win.ExportImage( filename, 1280, 960 );
This version, curiously did not give a run time error, but didn’t
export the image either. Darn!
That is when I decided to simplify the problem to its barest
terms and use the following as export image2:
AB = new ActiveXObject("Broker.Application");
Win = AB.ActiveWindow;
num = 5;
filename = "Image2_" + num + ".png";
Win.ExportImage( filename, 1280, 960 );
This version worked. Success! I figured that if the simple
version worked, that it would be easy to index num or better to use some of
your code after we find the error.
Again, thanks for all your help.

You can just tack on the current date/time to
the file name. Try
something along these lines before exporting your image:
// e.g. Image_2008-8-6_14-22-33.png
rightNow = new Date();
fileName = "Image_" + rightNow.getFullYear() + "-" +
(rightNow.getMonth() + 1) + "-" + rightNow.getDate() + "_"
+
rightNow.getHours() + "-" + rightNow.getMinutes() +
rightNow.getSeconds() + ".png";
If you really want to get fancy, use "Buy_" or "Sell_"
instead
of "Image_" :)
Alternatively, you can just use seconds since the epoch:
// e.g. Image_438057023343... some crazy long number ...
rightNow = new Date();
fileName = "Image_" + rightNow.getTime(); + ".png";
