  - by phenevo

  Hi, I have program which writes to database which folders are full or empty.

• Can IDL create a contour plot colorbar like this?

  - by Carthage

  At the bottom of this image, you'll see a nice colorbar that matches the colors of the graph correctly: http://stribog.cc.umanitoba.ca/ceos/20100517_00z_prod/ I couldn't find anything that created a color bar with exactly the colors I wanted, it always seemed to involve a spectrum that included colors I didn't use. I have a vector of colors I use for my data. Is there I way I can use that vector to create a color bar with only those colors?

• How should I collect dependencies from Adobe Flex files?

  - by eswald

  I'm looking for a way to collect the dependencies from Flex ActionScript and MXML files. I was hoping that mxmlc could spit them out (like gcc's -M option), but its option list doesn't seem to have anything relevant. I could write a parser, but would prefer not to reinvent the wheel if it has already been done, particularly given the two very different languages involved. Is there a program available to do this for me?

• Event when the user changes font size in browser?

  - by Christian

  I need to get informed when the user changes the font size in it's browser. I need it to reposition some elements which have to be relative in one dimension to an anchor inside a text. So far i haven't found anything and i'm a bit worried that it's not possible. In this case it should be possible to emulate it with a hidden div and some text inside and a script polling for changes of it's width. But i hope someone has a more elegant solution.

• HTTP triggers for Postgres

  - by HeineyBehinds

  I'm trying to write a Postgres trigger such that when a configuration table is updated, a backend component is notified and can handle the change. I know that Oracle has the concept of a web/HTTP trigger, where you can execute an HTTP GET from the Oracle instance itself to a URL that can then handle the request at the application layer. I'm wondering if Postgres (v. 9.0.5) has the same feature, or comes with anything similar (and, subsequently, how to set it up/configure it)?

• Does F# have an equivalent to Haskell's take?

  - by McMuttons

  In Haskell, there is a function "take n list" which returns the first n elements from a list. For example "sum (take 3 xs)" sums up the first three elements in the list xs. Does F# have an equivalent? I expected it to be one of the List-functions, but I can't spot anything that seems to match.

• Android: how to obtain AssetManager without reference to Context?

  - by ab11

  I have a Class that needs to obtain a reference to it's application's AssetManager. This class does not extend any sort of android UI class, so it doesn't have a getContext() method, or anything similar. Is there some sort of static Context.getCurrentApplicationContext() type of method? To clarify: my class is intended to be used like a library, for other applications. It has no associated AndroidManifest.xml or control over the context which is calling it.

• C++ dictionary/map with added order

  - by Gopalakrishnan Subramani

  I want to have something similar to map but while iterating I want them to be in the same order as it is added. Example map.insert("one", 1); map.insert("two", 2); map.insert("three", 3); While iterating I want the items to be like "one", ""two", "three"..By default, map doesn't provide this added order. How to get the map elements the way I have added? Anything with STL is fine or other alternative suggestions also fine

• Using "null" in jQuery functions. Is this okay?

  - by Nick

  My database consists of some entries which are NULL (so they don't affect max, min, etc..). When I pull all of the data from the database, I need to repopulate form fields with the values. Using .val(value) where value = NULL seems to work without any problems, but I'm not sure if this is a valid way to go about this. It doesn't say anything in the jQuery documentation (that I can find) about using NULL as parameters to functions.

• Why can't I make my parameter like this?

  - by mystify

  - (void)setPropertyValue:(const *void)inValue forID:(UInt32)propertyID { } The compiler doesn't like the const *void, for some reason. When I have that, it says: error: expected ')' before 'void' When I make the parameter like (UInt32)foo there is no problem. Does const *void only work in functions? I need a parameter which can be a "pointer to anything" like UInt32, Float64, etc.
