  • Rails: saving a string on an object -- syntax problem?

    - by Veep
    Hey there, I am trying to write a simple function to clean a filename string and update the object. When I save a test string it works, but when I try to save the string variable I've created, nothing happens. But when I return the string, the output seems to be correct! What am I missing? def clean_filename clean_name = filename clean_name.gsub! /^.*(\\|\/)/, '' clean_name.gsub! /[^A-Za-z0-9\.\-]/, '_' clean_name.gsub!(/\_+/, ' ') #update_attribute(:filename, "test") #<-- correctly sets filename to test #update_attribute(:filename, clean_name) #<-- no effect????? WTF #return clean_name <-- seems to returns the correct string end Thank you very much.

  • XAML Binding to property

    - by imslavko
    I have check box in my XAML+C# Windows Store application. Also I have bool property: WindowsStoreTestApp.SessionData.RememberUser which is public and static. I want check box's property IsChecked to be consistent (or binded, or mapped) to this bool property. I tried this: XAML <CheckBox x:Name="chbRemember1" IsChecked="{Binding Mode=TwoWay}"/> C# chbRemember1.DataContext = SessionData.RememberUser; Code for property: namespace WindowsStoreTestApp { public class SessionData { public static bool RememberUser { get; set; } } } But it doesn't seem to work. Can you help me?

  • Need help with java map and javabean

    - by techoverflow
    Hi folks, I have a nested map: Map<Integer, Map<Integer, Double>> areaPrices = new HashMap<Integer, Map<Integer, Double>>(); and this map is populated using the code: while(oResult.next()) { Integer areaCode = new Integer(oResult.getString("AREA_CODE")); Map<Integer, Double> zonePrices = areaPrices.get(areaCode); if(zonePrices==null) { zonePrices = new HashMap<Integer, Double>(); areaPrices.put(areaCode, zonePrices); } Integer zoneCode = new Integer(oResult.getString("ZONE_CODE")); Double value = new Double(oResult.getString("ZONE_VALUE")); zonePrices.put(zoneCode, value); myBean.setZoneValues(areaPrices); } I want to use the value of this Map in another method of the same class. For that I have a bean. How do I populate it on the bean, so that I can get the ZONE_VALUE in this other method In my bean I added one new field as: private Map<Integer, Map<Integer, Double>> zoneValues; with getter and setter as: public Map<Integer, Map<Integer, Double>> getZoneValues() { return zoneValues; } public void setZoneValues(Map<Integer, Map<Integer, Double>> areaPrices) { this.zoneValues = areaPrices; } What I am looking for to do in the other method is something like this: Double value = myBean.get(areaCode).get(zoneCode); How do I make it happen :(

  • Nullable values in C++

    - by DanDan
    I'm creating a database access layer in native C++, and I'm looking at ways to support NULL values. Here is what I have so far: class CNullValue { public: static CNullValue Null() { static CNullValue nv; return nv; } }; template<class T> class CNullableT { public: CNullableT(CNullValue &v) : m_Value(T()), m_IsNull(true) { } CNullableT(T value) : m_Value(value), m_IsNull(false) { } bool IsNull() { return m_IsNull; } T GetValue() { return m_Value; } private: T m_Value; bool m_IsNull; }; This is how I'll have to define functions: void StoredProc(int i, CNullableT<int> j) { ...connect to database ...if j.IsNull pass null to database etc } And I call it like this: sp.StoredProc(1, 2); or sp.StoredProc(3, CNullValue::Null()); I was just wondering if there was a better way than this. In particular I don't like the singleton-like object of CNullValue with the statics. I'd prefer to just do sp.StoredProc(3, CNullValue); or something similar. How do others solve this problem?

Can it be done without joins? I'm working with DB2, but answers in all SQL types would be helpful.

  • dm_exec_query_stats returning stale data?

    - by VoiceOfUnreason
    I've been testing my app on a SQL Server 2005 database, and am trying to establish a preliminary picture of the query performance using sys.dm_exec_query_stats. Problem: there's a particular query that I'm interested in, because total_elapsed_time and last_elapsed_time are both large numbers. When I tickle my app to invoke that query (this runs successfully), then refresh my view of the stats, I find that 1) execution_count has incremented (expected) 2) last_execution_time has updated to now (expected) 3) last_elapsed_time is still a large value (not expected - I anticipated a new value) 4) total_elapsed_time is unchanged (contradiction?) If last_elapsed_time refers to the execution that happened @ last_execution_time, then the total_elapsed_time should have increased? This documentation: http://msdn.microsoft.com/en-us/library/ms189741(SQL.90).aspx tells me that last_execution_time is the last time the plan was executed, and last_elapsed_time comes from the "most recently executed plan", but doesn't tell me why those might be different. The query itself is uncomplicated (SELECT/WHERE/ORDER BY - parameters appearing in the where clause, but no clever operations), the table has maybe 25 rows in it right now. Questions: 1) What's the real relationship between execution_count, last_execution_time, and last_elapsed_time? 2) Where is the documentation of this relationship (manual, third party book, blog, bug ticket, stone tablets...) ?

  • Export SQL Binary/BLOB Data?

    - by davemackey
    Recently a software application we utilize upgraded from ASP to ASP.NET. In the process they abandoned the old web-based product and rewrote the entire UI, using new DB tables. The old DB tables still exist in the database and contain legacy files in binary or blob formats. I'm wondering if there is an easy way to export all these legacy files from the database to the filesystem (NTFS)? Then we could delete these old unused tables and save a few GB of space in the DB backups, etc.

  • Serializing data from a RSS feed in ASP.NET

    - by DotnetDude
    I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?

Here is an example of the typical information. I need to be able to know that work order 5678 does not have an "RW" Resource ID. WO Number - Resource ID 1234 - IN 1234 - WE 1234 - AS 1234 - RW 5678 - PR 5678 - WE 5678 - IN 5678 - AS

  • confusing java data structures

    - by London
    Maybe the title is not appropriate but I couldn't think of any other at this moment. My question is what is the difference between LinkedList and ArrayList or HashMap and THashMap . Is there a tree structure already for Java(ex:AVL,Black-white) or balanced or not balanced(linked list). If this kind of question is not appropriate for SO please let me know I will delete it. thank you

  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • highlighting data values in a sql result set

    - by potatoe
    I can think of a number of ways to do this in PHP or even JavaScript, but I'm wondering if there's a SQL-based technique I'm overlooking. I have a database table, let's say 20 fields X 10 rows. I want to display the entire table on an web page, so I'd do something like SELCT * FROM data_table;, and then format the result set using HTML table tags. However, I'd also like to highlight values in the table based on whether they are the maximum or minimum value in their column. For example, I'd add bold tags around the max in each column. A resulting table might look something like this, with bold tags shown: id | field1 | field2 | field3 | ... 0 | 5 | 2 | <b>7</b> | ... 1 | 3 | <b>8</b> | 6 | ... 2 | <b>9</b> | 5 | 1 | ... ... I could do a separate SELECT with an ORDER BY for each field and then interpret the results, but that seems like a lot of extra DB access. My alternative right now is to just fetch the whole table, and then sort/search for the highlight values using PHP. Is there a better way?

  • C# massive insertion into data structures

    - by Seabass
    In C#, you can do the following: List registers = new List { 1, 2, 3, 4 }; This will produce a list with 1, 2, 3, and 4 in the list. Suppose that I am given a list from some function and I want to insert a bunch of numbers like the following: List register = somewhere(); register.Add(1); register.Add(2); register.Add(3); register.Add(4); Is there a cleaner way of doing this like the snippet above?

  • WMF image data validation?

    - by deostroll
    There is an image capturing device which gives its output in wmf. This output is stored in the database directly. We have cases where at times some of these images do not appear on a web page in IE. But if we right click on the page we are able to save the image on to the hard disk; meaning the image does exist on the page, but does not appear visible. I think this is because of some file corruption issue, but I don't know how to resolve it. We are however able to view such files using MS Picture Viewer (desktop app). Is there anyway we can detect such problematic files?

  • AS3/AIR: Managing Run-Time Image Data

    - by grey
    I'm developing a game with AS3 and AIR. I will have a large-ish quantity of images that I need to load for display elements. It would be nice not to embed all of the images that the game needs, thereby avoiding having them all in memory at once. That's okay in smaller projects, but doesn't make sense here. I'm curious about strategies for loading images during run time. Since all of the files are quite small and local ( in my current project ) loading them on request might be the best solution, but I'd like to hear what ideas people have for managing this. For bonus points, I'm also curious about solutions for loading images on-demand server-side as well.
