Does IQ and any specific aptitude have a bearing on whether or not someone can become a good software developer? It seems to me that SE are mostly clever folks and love theoretical problems. Does it mean if you have a low IQ or are horrendous at logical puzzles that you would suck at Software development? In your experience. ...
Hello, I've read with interest the techniques available on the web to extract a unique list of items from a XML file containing duplicates using XSL. These range into 2 categories: 1) The Muenchian method (example: http://www.jenitennison.com/xslt/grouping/) 2) Or the previous-sibling look-up These both rely on an XPath expression to s...
Someone asked me this today after a failed file move, and I was not sure what to tell them. When you build a .NET deployment package you get the setup.exe and the .msi files. I know that the .msi file is needed... but for the setup.exe, is that unique? Meaning, can we just move the .msi file and be fine, or do we need to keep the two to...

Is it possible to set a unique constraint as a foreign key in another table? If yes, how would you go about declaring it? How would you go about assigning a candidate key? Is it possible? Sorry, I'm a real noob at oracle. Example: I have a product table that consists of: prod_id, prod_name, prod_price, QOH Where I want prod_name to ...
Say you have a bunch of Article objects, with a "title" property. Then there's an ARTICLE table with a TITLE column. The TITLE column has a unique constraint. The UI shows all the articles on one page, with a text field for editing the title. Imagine a situation where you have two articles X & Y, X having the title "1" and Y having the...
I 'RTFM' and did not find a way to retrieve the columns involved in a unique constraint for a given schema and table. Somewhere I read that there should be an implicitly created unique index, which backs the unique constraint. Its name is supposed to be equal to the name of the conglomerate that corresponds to the unique constraint. So...
Hello, The problem is the following, I have a table of friendships in my database, the friendship table has two foreign keys to the users table. I want to set a unique key on the two foreign keys so that I will have no duplicates, but I want more, I want that if user A added user B, then B won't be able to add A, and I want to have on...

Hi, I come from a C/C++ background and am having trouble doing some things in C#. My problem right now is that I need a static keyword that works like in C++. So that the property is global to all instances of the class, which is what C#'s does. But what I don't want is the persistence in C#(/ASP.NET). I want the static property global t...

Hi, I am creating huge amounts of dynamic controls, and for everything that must have an ID assigned, I assign it using a guaranteed unique variable(unless 64bits overflows from just controls). Now, I have a problem though. I have a duplicate control somewhere and I can not discover where it is added or anything because it doesn't happe...
Currently I have this query: SELECT column1,column2 FROM table column1 needs to be distinct, column2 does not. SELECT DISTINCT column1, NON-DISTINCT column2 FROM table Now I know that doesn't make sense but I need column1 to be distinct and column2 to be anything. How would I do that. ...
Although i have specified a unique key, it seems the following code will return one value for 5 requests, then another for the next couple, then revert back to the value saved in the original request and just continue until there are 10's of different objects all stored under the same key. It then seems almost random which of these value...
Can anyone point me as to why the unique element in my XSD is not forcing unique-ness? This should throw an error because the last ScreenResult element does not contain a unique value for the Type attribute. I should also note that I'm truly after forcing one of each Type within ScreenResults (ScreenResult is required to exist 3 times,...
I have a vector containing few non-adjacent duplicates. As a simple example, consider: 2 1 6 1 4 6 2 1 1 I am trying to make this vector unique by removing the non-adjacent duplicates and maintaining the order of elements. Result would be: 2 1 6 4 The solutions I tried are: Inserting into a std::set but the problem with this a...
Hi all. I have a database of articles, which are stored in categories. For my homepage, I want to grab an article from each category (I don't care which). However, some articles are crossposted to multiple categories, so they come up twice. I have a table called tblReview with the article fields (reviewID, headline, reviewText) and a ...

Hi there, I'm using the SimpleModal Basic Modal Dialog and am having trouble using it to open more than one unique window on a page (I don't need them to open at the same time or on top of one another). I tried adding another class and calling out that class in my js file, but I'm not getting it. Here is my example page, where I have t...
