  • python: equivalent to Javascript "||" to override non-truthful value

    - by Jason S
    In Javascript I can do this: function A(x) { return x || 3; } This returns 3 if x is a "non-truthful" value like 0, null, false, and it returns x otherwise. This is useful for empty arguments, e.g. I can do A() and it will evaluate as 3. Does Python have an equivalent? I guess I could make one out of the ternary operator a if b else c but was wondering what people use for this.

  • C++ Template const char array to int

    - by Levi Schuck
    So, I'm wishing to be able to have a static const compile time struct that holds some value based on a string by using templates. I only desire up to four characters. I know that the type of 'abcd' is int, and so is 'ab','abc', and although 'a' is of type char, it works out for a template<int v> struct What I wish to do is take sizes of 2,3,4,5 of some const char, "abcd" and have the same functionality as if they used 'abcd'. Note that I do not mean 1,2,3, or 4 because I expect the null terminator. cout << typeid("abcd").name() << endl; tells me that the type for this hard coded string is char const [5], which includes the null terminator on the end. I understand that I will need to twiddle the values as characters, so they are represented as an integer. I cannot use constexpr since VS10 does not support it (VS11 doesn't either..) So, for example with somewhere this template defined, and later the last line template <int v> struct something { static const int value = v; }; //Eventually in some method cout << typeid(something<'abcd'>::value).name() << endl; works just fine. I've tried template<char v[5]> struct something2 { static const int value = v[0]; } template<char const v[5]> struct something2 { static const int value = v[0]; } template<const char v[5]> struct something2 { static const int value = v[0]; } All of them build individually, though when I throw in my test, cout << typeid(something2<"abcd">::value).name() << endl; I get 'something2' : invalid expression as a template argument for 'v' 'something2' : use of class template requires template argument list Is this not feasible or am I misunderstanding something?

  • ASP.NET MVC Inheriting from ProfileBase

    - by Glen
    I have 2 related issues. I inherited from ProfileBase and I have a couple of properites as such public SomeType PropertyName { get { return (SomeType)base["PropertyName"]; } set { base["PropertyName"] = value; Save(); } } I also have a User class (UserId, UserName, Profile, LastActivityDate) that has 2 additional properties out of the profile that I retrieve in my View to show a list of Users (i.e. @Model.Profile.PropertyName). However, everytime I access a property (from my View) it seems to update the LastActivityDate in the aspnet_Users table because when I show the LastActivityDate as well as the profile properties on my screen the LastActivtyDate is out of sync with the database. Also there is a LastActivityDate property available in my profile which unfortunately is not available and is in fact set to null and throws an exception when accessing it saying the property UserName is null. So the static Create method provided by ProfileBase seems to retrieve the correct profile properties but does not set the base's UserName property even though you pass in a UserName parameter to the Create method. Is this a internal bug? I was kind of hoping if by accessing the property because the LastActivityDate is updated then I could store that value to update my LastActivityDate in my User class before it is rendered to the page. The only way I can think of doing it is: public SomeType PropertyName { get { SomeType result = (SomeType)base["PropertyName"]; OnLastActivityDateChanged(); return result; } set { base["PropertyName"] = value; } } then in my User class: ... public MyProfile() { Profile.LastActivityDateChanged += Profile_LastActivityDateChanged(); } ~MyProfile() { Profile.LastActivityDateChanged -= Profile_LastActivityDateChanged(); } ... void Profile_LastActivityDateChanged(object sender, EventArgs e) { //Run a query to get the latest LastActivityDate this.LastActivityDate = ... } It seems I have to make 1 call to retrieve the full list to my aspnet_Users table then another call for each row just to get the latest activity date. ARGGGGHHH!!! Am I going about this the wrong way! I put an ajax refresh hyperlink next to each User row and when I click it, immediately after loading the page, the value changes. Therefore my suspision is valid that calling a property via the inherited profilebase class updates the value. Is there a workaround? It is a bit miss leading when my page says User Smith has no activity for 4 days then I click my ajax refresh link (or refresh the whole page for that matter) and now it says Smith was active but it was just me meally showing the page that indirectly caused an activity read event.

  • Delayed instantiation with c# using statment

    - by fearofawhackplanet
    Is there any way to write a using statement without instantiating the IDisposable immediately? For example, if I needed to do something like: using (MyThing thing) { if (_config == null) { thing = new MyThing(); } else { thing = new MyThing(_config); } // do some stuff } // end of 'using' Is there an accepted pattern for cases like this? Or am I back to handling the IDisposable explicitly again?

  • JDBC Code Change From SQL Server to Oracle

    - by BeginnerAmongBeginners
    In the JDBC code, I have the following that is working with SQL Server: CallableStatement stmt = connection.prepareCall("{ call getName() }"); ResultSet rs = stmt.executeQuery(); if(rs != null) { while(rs.next()) { //do something with rs.getString("name") } } Multiple rows are returned for the above situation. I understand that the use of a cursor is required to loop through the table in Oracle, but is there any way to keep the above code the same and accomplish the same thing? Thanks in advance.

  • How can I store large amount of data from a database to XML (speed problem, part three)?

    - by Andrija
    After getting some responses, the current situation is that I'm using this tip: http://www.ibm.com/developerworks/xml/library/x-tipbigdoc5.html (Listing 1. Turning ResultSets into XML), and XMLWriter for Java from http://www.megginson.com/downloads/ . Basically, it reads date from the database and writes them to a file as characters, using column names to create opening and closing tags. While doing so, I need to make two changes to the input stream, namely to the dates and numbers. // Iterate over the set while (rs.next()) { w.startElement("row"); for (int i = 0; i < count; i++) { Object ob = rs.getObject(i + 1); if (rs.wasNull()) { ob = null; } String colName = meta.getColumnLabel(i + 1); if (ob != null ) { if (ob instanceof Timestamp) { w.dataElement(colName, Util.formatDate((Timestamp)ob, dateFormat)); } else if (ob instanceof BigDecimal){ w.dataElement(colName, Util.transformToHTML(new Integer(((BigDecimal)ob).intValue()))); } else { w.dataElement(colName, ob.toString()); } } else { w.emptyElement(colName); } } w.endElement("row"); } The SQL that gets the results has the to_number command (e.g. to_number(sif.ID) ID ) and the to_date command (e.g. TO_DATE (sif.datum_do, 'DD.MM.RRRR') datum_do). The problems are that the returning date is a timestamp, meaning I don't get 14.02.2010 but rather 14.02.2010 00:00:000 so I have to format it to the dd.mm.yyyy format. The second problem are the numbers; for some reason, they are in database as varchar2 and can have leading zeroes that need to be stripped; I'm guessing I could do that in my SQL with the trim function so the Util.transformToHTML is unnecessary (for clarification, here's the method): public static String transformToHTML(Integer number) { String result = ""; try { result = number.toString(); } catch (Exception e) {} return result; } What I'd like to know is a) Can I get the date in the format I want and skip additional processing thus shortening the processing time? b) Is there a better way to do this? We're talking about XML files that are in the 50 MB - 250 MB filesize category.

  • synchronized in java - Proper use

    - by ZoharYosef
    I'm building a simple program to use in multi processes (Threads). My question is more to understand - when I have to use a reserved word synchronized? Do I need to use this word in any method that affects the bone variables? I know I can put it on any method that is not static, but I want to understand more. thank you! here is the code: public class Container { // *** data members *** public static final int INIT_SIZE=10; // the first (init) size of the set. public static final int RESCALE=10; // the re-scale factor of this set. private int _sp=0; public Object[] _data; /************ Constructors ************/ public Container(){ _sp=0; _data = new Object[INIT_SIZE]; } public Container(Container other) { // copy constructor this(); for(int i=0;i<other.size();i++) this.add(other.at(i)); } /** return true is this collection is empty, else return false. */ public synchronized boolean isEmpty() {return _sp==0;} /** add an Object to this set */ public synchronized void add (Object p){ if (_sp==_data.length) rescale(RESCALE); _data[_sp] = p; // shellow copy semantic. _sp++; } /** returns the actual amount of Objects contained in this collection */ public synchronized int size() {return _sp;} /** returns true if this container contains an element which is equals to ob */ public synchronized boolean isMember(Object ob) { return get(ob)!=-1; } /** return the index of the first object which equals ob, if none returns -1 */ public synchronized int get(Object ob) { int ans=-1; for(int i=0;i<size();i=i+1) if(at(i).equals(ob)) return i; return ans; } /** returns the element located at the ind place in this container (null if out of range) */ public synchronized Object at(int p){ if (p>=0 && p<size()) return _data[p]; else return null; }

  • Selenium navigation inside foreach loop

    - by smudgedlens
    I am having an issue with navigation. I get a list of rows from an html table. I iterate over the rows and scrape information from them. But there is also a link on the row that I click to go to more information related to the row to scrape. Then I navigate back to the page with the original table. This works for the first row, but for the subsequent rows, it throws an exception. I look at my row collection after the first time the link inside a row is clicked, and none of them have the correct values like they did before I clicked the link. I believe that there is something going on when I navigate to a different URL that I'm not getting. My code is below. How do I get this working so I can iterate over the parent table, click the links in each row, navigate to the child table, but still continue iterating over the rows in the parent table? private List<Document> getResults() { var documents = new List<Document>(); //Results IWebElement docsTable = this.webDriver.FindElements(By.TagName("table")) .Where(table => table.Text.Contains("Document List")) .FirstOrDefault(); var validDocRowRegex = new Regex(@"^(\d{3}\s+)"); var docRows = docsTable.FindElements(By.TagName("tr")) .Where(row => //It throws an exception with .FindElement() when there isn't one. row.FindElements(By.TagName("td")).FirstOrDefault() != null && //Yeah, I don't get this one either. I negate the match and so it works?? !validDocRowRegex.IsMatch( row.FindElement(By.TagName("td")).Text)) .ToList(); foreach (var docRow in docRows) { //Todo: find out why this is crashing on some documents. var cells = docRow.FindElements(By.TagName("td")); var document = new Document { DocID = Convert.ToInt32(cells.First().Text), PNum = Convert.ToInt32(cells[1].Text), AuthNum = Convert.ToInt32(cells[2].Text) }; //Go to history for the current document. cells.Where(cell => cell.FindElements(By.TagName("a")).FirstOrDefault() != null) .FirstOrDefault().Click(); //Todo: scrape child table. this.webDriver.Navigate().Back(); } return documents; }
