I want to avoid this behavior.

• Parameterized include in Classic ASP with VBScript

  - by Thom Smith

  I want to write a function that will include an external file, much like Server.Execute, but will pass along parameters. I'm aware that Server.Execute will pass along query parameters, but I'd like to pass data more generally. For instance: ' main.asp MyInclude("external.inc", Array("mykey", "myval")) ' external.inc Response.Write mykey I doubt I can get quite that far without reading the external fine, twiddling it, and executing, but I'd like to get as close as reasonably possible. Also, if possible, I'd prefer avoiding using the query passing option for security reasons.

• Reading from an embedded resource stream

  I've been trying to access an image resource named "IndexPointer.jpg" in an embedded RESX file called "Images.resx". GetManifestResourceNames() returns a single value - SCtor.Images.resources". Assembly::GetExecutingAssembly()-GetManifestResourceStream("SCtor.Images.resources.IndexPointer.jpg") only returns a nullptr. Obviously, I've got the manifest name wrong. What would be the correct one ?

• Java Google App Engine Datastore: 'IN' operator available on JDO query filters, as with Python?

  - by Jim Blackler

  This page describes an 'IN' operator that can be used in GAE Datastore to compare a field against a list of possible matches, not just a single value: However this is for Python. In Java (App Engine 1.2.5), trying query.setFilter("someField IN param"); on my javax.jdo.query fires a JDOUserException 'Portion of expression could not be parsed: IN param'. Is there a way this can be done?

• What should be the ideal number of parallel java threads for copying a large set of files from a qua

  - by ukgenie

  What should be the ideal number of parallel java threads for copying a large set of files from a quad core linux box to an external shared folder? I can see that with a single thread it is taking a hell lot of time to move the files one by one. Multiple threads is improving the copy performance, but I don't know what should be the exact number of threads. I am using Java executor service to create the thread pool.

• Move jQuery data() when an element is destroyed and re-created

  - by Ed Woodcock

  Can anyone think of a (preferably quick) way to move the data() attached to a DOM element to a new instance of itself? The lightbox plugin I'm using deletes and re-appends and element to the page in order to display it in the lightbox (to aviod the multiple-ids issue that ASP.net has), and obviously the .data() that is attached to the element is lost when this happens.

• Naming convention when casually referring to methods in Java

  - by polygenelubricants

  Is there a Java convention to refer to methods, static and otherwise, any specific one or the whole overload, etc? e.g. String.valueOf - referring to all overloads of static valueOf String.valueOf(char) - specific overload, formal parameter name omittable? String.split - looks like a static method, but actually an instance method Maybe aString.split is the convention? String#split - I've seen this HTML anchor form too, which I guess is javadoc-influenced Is there an authoritative recommendation on how to clearly refer to these things?
