• Function allocation

  - by novice_coder

  Where are functions stored in a C++ program? For example int abc() { //where am I stored? } I know that we can take the address of a function, that means functions are stored somewhere in memory. But I have already read at many places that no memory allocation for functions takes place. I am confused. My question may seem vague to many of you but I can't help.

• Can I configure a resource path that contains java source files in eclipse?

  - by tangens

  Motivation In eclipse I'd like to configure a path as a resource path. This path contains some java files that I only want to handle as resources, i.e. I don't want eclipse to try to compile these files. I only want to read them as resources from within junit tests. Question Is there a way to configure eclipse so it won't try to compile the java files it found there?

• [Design Question] When to open a link on a new window?

  - by Ian

  Hi All, When designing a web application/web site, is there an accepted practice on when to open a link on a new window? Currently, if the site being linked to is outside the domain (say Google.com), I am always launching it on a new window. If the page being linked is within the same domain, I open it on the current active window. I've read somewhere the opening links on a new window explicitly is being frowned upon. Thanks!

• Google App Engine, Secure Data Connector (SCD), and supported protocols

  - by Pablo Alvim

  I've been investigating what I can do with Google's Secure Data Connector and App Engine. Is it possible, from an App Engine application, to grab resources inside my corporate intranet without using HTTP(S)? From what I read in the documentation, the only way to request resources through SDC is by using url_fetch, which is limited to HTTP, right?

• SubSonic 3 LeftOuterJoin

  - by michaelpearce

  I have read in this forum that left outer join syntax is not supported by subsonic in an answer to a question on the topic by "Apocatastasis". I have the same issue in that when I create a query using the .LeftOuterJoin the resulting sql has an inner join rather than a left outer join. Can someone please confirm that LeftOuterJoin is indeed not supported and, if that is the case, why is it included in the active record syntax? Thanks Michael

• What is the correct position of braces or does it not matter

  - by TheLearner

  I noticed in Objective C that xcode automatically uses a strange position of braces: if (statement) { } whereas I am used to using: if (statement) { } it just makes it easier to read. Is it a matter of preference or is a standard that should be followed when writing Objective C applications?

• Using a CSV/Text-File as a RecordSource for a Report

  - by Falcon

  I need an Access Report to use a CSV-File as a RecordSource. I have searched and tried many things, yet, I've found no way to achieve this. A temporary table in some other database is not an option. I've been trying to use a DAO RecordSet, but while I can read the RecordSet just fine I cannot set it as the report's RecordSet and I cannot use its Name as the RecordSource Property as both approaches lead to an error. Please help me find a way!
