Is there a way to attach an event to a foreign / separate window from an .NET process that when the foreign window is closed or is about to close my application can be notified?

Thanks to the tip from Simon\_Weaver, here is another way you could do it, using [`serializeArray`](http://api.jquery.com/serializeArray/):
```
var values = {};

How do I iterate over a range of numbers in Bash when the range is given by a variable?
I know I can do this (called "sequence expression" in the Bash [documentation](http://www.gnu.org/software/bash/manual/bashref.html#Brace-Expansion)):
```
for i in {1..5}; do echo $i; done

The only way to be sure is with reflection, but 90% of the time you can avoid the cost of that by using `array is T[]`. Most people are going to pass a properly typed array in, so that will do. But, you should always provide the code to do the reflection check as well, just in cas... | [

Does anyone know how to resize images proportionally using JavaScript?
I have tried to modify the DOM by adding attributes `height` and `width` on the fly, but seems did not work on IE6.
To modify an image proportionally, simply only alter one of the width/height css properties, leave the other set to auto.
