a[2] = "Line 2";
foreach (string c in a)

<p>I have a sparse array in Jscript, with non-null elements occuring at both negative and positive indices. When I try to use a for in loop, it doesn't traverse the array from the lowest (negative) index to the highest positive index. Instead it returns the array in the order that I added the elements. Enumeration does... | <p>Technically, "A" isn't in the Array at all since you can't have a negative index. It is just a member of the arrName object. If you check the arrName.length you will see that it is 21 (0,1,2,...,20) Why don't you use a plain object instead (as a hashtable). Something like this should work:</p>

Avoiding the cost of virtual function calls while retaining some of the hierarchical benefits is an enormous win for the subsystems where it can be done in the project I am currently working on. </p>
| <p>Generally it is used for polymorphic-like patterns where you do not need to be able to choose the derived class at runtime, only at compile time. This can save the overhead of the virtual function call at runtime.</p>

<p>I'm sure this one is easy but I've tried a ton of variations and still cant match what I need. The thing is being too greedy and I cant get it to stop being greedy.</p>

<p>Are Adobe's plugin architectures for Photoshop and Lightroom related in any way? If I have source code for a plugin, that works with PS 3.0-CS3 as well as PS Elements 6.0 can I use it with Lightroom directly? If not, what would I have to modify?</p>
| <p>No.. lightroom plugins are written in the scripting language lua, photoshop plugins are written in C++.</p>
| <p>As pointed out by Rob, the Lightroom SDK does not expose any interface that allows manipulations of the image files themselves. Partly this is because Lightroom is a non-destructive editor. None of the edits made in its Develop module are applied to the original image file; they are applied to the file generated whe... | 34,313 |
