  • Design question - loading info from DB

    - by eriks
    I need to build a class that will represent a row in some table in DB (lets say the table is 'Subscriber' and so is the class). I can have the class Subscriber which constructor receives the Objectkey of subscriber, retrieves info from DB and initializes its members. I add another class - SubscriberLoader which have a static method 'LoadSubscriber'. This method will receive the subscriber objectkey, retrieve info from DB, crate a Subscriber object and initialize its members. Subscriber constructor will be private and SubscirberLoader will be friend class of Subscriber - this way, client could build a Subscriber only using the loader. which of the two in better? any other suggestions?

  • Passing information between test methods in a junit testcase

    - by Jijoy
    Hi, Currently I am creating a TestCase for one work flow and a workflow have different steps. The results of one step is important since , second step needs to know value of step1's execution. class TestCaseWorkFlow1 extends TestCase { private static String resultOfStep1 = null; public void testStep1(){ if(failed){ resultOfStep1 = "failed"; } } public void testStep2(){ if(resultOfStep1 != null ) { //First test failed. }else { } } } Currently we are using static variable to pass information between testmethods . What is the best solution for this scenario ? Please help. Thanks J

  • Why this works (Templates, SFINAE). C++

    - by atch
    Hi guys, reffering to yesterday's post, this woke me up this morning. Why this actually works? As long as the fnc test is concerned this fnc has no body so how can perform anything? Why and how this works? I'm REALLY interested to see your answers. template<typename T> class IsClassT { private: typedef char One; typedef struct { char a[2]; } Two; template<typename C> static One test(int C::*); //NO BODY HERE template<typename C> static Two test(…); //NOR HERE public: enum { Yes = sizeof(IsClassT<T>::test<T>(0)) == 1 }; enum { No = !Yes }; }; Thanks in advance with help to understand this very interesting fenomena.

  • Two-key encryption/decryption?

    - by Matt
    I'm looking to store some fairly sensitive data using PHP and MySQL and will be using some form of reversible encryption to do so since I need to get the data back out in plain text for it to be of any use. I'll be deriving the encryption key from the users' username/password combination but I'm stumped for what to do in the (inevitable) event of a password being forgotten. I realise that the purpose of encryption is that it can only be undone using the correct key but this must have been addressed before.. I'm trying to get my head around whether or not public key cryptography would apply to the problem but all I can think of is that the private key will still need to be correct to decrypt the data.. Any ideas?

  • On Mac OS X, do you use the shipped python or your own?

    - by The MYYN
    On Tiger, I used a custom python installation to evaluate newer versions and I did not have any problems with that*. Now Snow Leopard is a little more up-to-date and by default ships with $ ls /System/Library/Frameworks/Python.framework/Versions/ 2.3 2.5 2.6 @Current What could be considered best practice? Using the python shipped with Mac OS X or a custom compiled version in, say $HOME. Are there any advantages/disadvantages using the one option over the other? My setup was fairly simple so far and looked like this: Custom compiled Python in $HOME and a $PATH that would look into $HOME/bin first, and subsequently would use my private Python version. Also $PYTHONPATH pointed to this local installation. This way, I did not need to sudo–install packages - virtualenv took care of the rest.

    - by Dmitry Makovetskiyd
    I get my page content with this function: private function fetch_url($url){ $ch=curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 320); $this->doc = curl_exec($ch); $this->status_code= curl_getinfo($ch, CURLINFO_HTTP_CODE); // echo $this->doc; curl_close($ch); } The problem is that with some urls dont exist on a webpage and there is a redirect to another page..

  • C# Serial Communications - Received Data Lost

    - by Jim Fell
    Hello. Received data in my C# application is getting lost due to the collector array being over-written, rather than appended. private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e) { try { pUartData_c = serialPort1.ReadExisting().ToCharArray(); bUartDataReady_c = true; } catch ( System.Exception ex ) { MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } } In this example pUartData_c is over-written every time new data is received. On some systems this is not a problem because the data comes in quickly enough. However, on other systems data in the receive buffer is not complete. How can I append received data to pUartData_c, rather than over-write it. I am using Microsoft Visual C# 2008 Express Edition. Thanks.

  • How to find the right object in a Rails controller based on two variables?

    - by sscirrus
    Hi everyone, I have a three-table system: Companies, Customers, and Matches. The matches include, for example, private notes that each party makes about the other and some options they can set regarding the other. I have two sets of views centered around Companies and Customers for each party to look at the other and modify their notes and settings. # Customers Controller def show @customer = Customer.find(params[:customer]) @matchings = @candidate.matchings.find... @company = Company.find(params[:company]) end Obviously the @matchings is incomplete. Given that @matchings has fields customer_id and company_id, how do I find the right matching record? Thank you!

    I have a collection of Contacts that inherits from CollectionBase: public class ContactCollection : CollectionBase{ //... } each contact in the collection has a unique ID: public class Contact{ public int ContactID{ get; private set; } //... } I think what I would like to do is something like the following: // get the contact by their unique [Contact]ID Contact myPerson = Contact.GetContactById(15); // get all contacts for the customer ContactCollection contacts = customer.GetContacts(); // replaces the contact in the collection with the // myPerson contact with the same ContactID. contacts.ReplaceAt(myPerson); // saves the changes to the contacts and the customer // customer.Save(); There is probably a better way...if so, please suggest it.

  • How to speed up dumping a DataTable into an Excel worksheet?

    - by AngryHacker
    I have the following routine that dumps a DataTable into an Excel worksheet. private void RenderDataTableOnXlSheet(DataTable dt, Excel.Worksheet xlWk, string [] columnNames, string [] fieldNames) { // render the column names (e.g. headers) for (int i = 0; i < columnNames.Length; i++) xlWk.Cells[1, i + 1] = columnNames[i]; // render the data for (int i = 0; i < fieldNames.Length; i++) { for (int j = 0; j < dt.Rows.Count; j++) { xlWk.Cells[j + 2, i + 1] = dt.Rows[j][fieldNames[i]].ToString(); } } } For whatever reason, dumping DataTable of 25 columns and 400 rows takes about 10-15 seconds on my relatively modern PC. Takes even longer testers' machines. Is there anything I can do to speed up this code? Or is interop just inherently slow?

  • Identifying the view selected in a ContextMenu (Android)

    - by Casebash
    In Android, onContextItemSelected has a single MenuItem argument and so it isn't clear how to identify the view selected. MenuItem.getMenuInfo provides access to Contextmenu.ContextMenuInfo, but while both known subclasses provide access to the target view, there does not appear to be an accessor on the interface. One alternative is to save the View provided in onCreateContextMenu in a private class variable which relies on onCreateContextMenu not being called again in the activity before onContextItemSelected. Another is to use the id of the View for the itemId argument of ContextMenu.add. If we do this, we would then need to identify the option selected from the context menu by using its (possibly internationalised) title. What is the best method for identifying the View selected in onContextSelected?

  • How to look up an NHibernate entity's table mapping from the type of the entity?

    - by snicker
    Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code? Example: The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere. How can I make the following test pass? private const string LegacyPonyTableName = "AAZF1203"; [Test] public void MakeSureThatThePonyEntityIsMappedToCorrectTable() { string ponyTable = GetNHibernateTableMappingFor(typeof(Pony)); Assert.AreEqual(LegacyPonyTableName, ponyTable); } In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

  • Would you make this method Static or not?

    - by Adam Drummond
    During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing. So I did quite a bit of research and obviously it's a specialized case but I would like to know what you would do in this situation and why? (Its basically a helper method I call from a few different methods, a very low traffic page. More for my knowledge and learning on Static.) private IEnumerable<Category> GetCategoryByID(int id, Context context) { var categoryQuery = from selectAllProc in context.SelectAll_sp() where selectAllProc.CategoryID == id select selectAllProc; return categoryQuery; }

  • Is It Safe to Cast Away volatile?

But, is it safe? // Error : delete j; } private: volatile int i; volatile int *j; }; int main() { a aa; } However, I saw an article here: https://www.securecoding.cert.org/confluence/display/seccode/EXP32-C.+Do+not+access+a+volatile+object+through+a+non-volatile+reference Casting away volatile allows access to an object through a non-volatile reference. This can result in undefined and perhaps unintended program behavior. So, what will be the workaround for my above code example?

  • Twisted Spread: How to authenticate each RPC with digital signature

    - by kronat
    I have remote objects which talk each others with RPCs, using Twisted Spread. I want that objects authenticate messages, before using them, with digital signatures, but I don't know where to start to implement this. In my head, the Root object must have a public/private key pair, and the Client too. When a message is sent, a digital signature of the hash is added, and when it is received, the signature is checked. Is the Protocol part where I need to add these adds and checks? Thank you
