  • Should I use my models in a library?

    - by Piers
    I've got my auth library in codeigniter which accesses the database to check to see if the email/password combination is correct. If I'm sticking to the MVC practice, should I move the function that interacts with the database to my model, or is it best practice to leave it where it is so I can use it in the future? Doesn't make much difference to me, other than the fact I'd have to re-write the library and create the function in my model, but if that's the way it should be then so be it.

  • Python tkInter text entry validation

    - by meade
    I'm trying to validate the entry of text using Python/tkInter def validate_text(): return False text = Entry(textframe, validate="focusout", validatecommand=validate_text) where validate_text is the function - I've tried always returning False and always returning True and there's no difference in the outcome..? Is there a set of arguments in the function that I need to include? Edit - changed from NONE to focusout...still not working

  • Android which button index from array was pressed

    - by Tim Wayne
    How do I set up a OnClickListener to simply tell me which index button was pressed from an array of buttons. I can change text and color of these buttons using the array. I set them up like this. TButton[1] = (Button)findViewById(R.id.Button01); TButton[2] = (Button)findViewById(R.id.Button02); TButton[3] = (Button)findViewById(R.id.Button03); up to 36.

    The connection string in my app.config for my C# project looks like Data Source=.\SQLEXPRESS;AttachDbFilename='|DataDirectory|\EIC.mdf';Integrated Security=True;User Instance=True" I am writing unit tests for the project and have the set the test run configuration to copy the EIC.mdf, but I do am not able to reference the Deployed copy of EIC.mdf to be referenced by the app.config I created for the test project. If I set it to Data Source=.\SQLEXPRESS;AttachDbFilename='EIC.mdf';Integrated Security=True;User Instance=True" It still does not find the mdf file.

  • what is the point of return in ruby?

    - by Sam
    What is the difference between return and just putting a variable such as the following: return def write_code(number_of_errors) if number_of_errors > 1 mood = "WTF" else mood = "No Problem" end mood end no return def write_code(number_of_errors) if number_of_errors > 1 mood = "WTF" else mood = puts "No Problem" end return mood end

  • mysqli_stmt_bind_param SQL Injection

    - by profitphp
    Is there still an injection risk when using prepared statements and mysqli_stmt_bind_param? For example: $malicious_input = 'bob"; drop table users'; mysqli_stmt_bind_param($stmt, 's', $malicious_input); Behind the scenes does mysqli_stmt_bind_param pass this query string to mysql: SET @username = "bob"; drop table users"; Or does it perform the SET command through the API, or use some type of protection to keep this from happening?

  • Multiple Settings for One Monitor

    - by Lynda
    I have my monitor set to the way I like it, it shows colors accurately and not overly bright (white doesn't blind me). However I edit photos for the web and this is great for my screen but I have noticed when looking at other screens my photos will at times looked washed out and not a good presentation. If I manually change my monitor settings to be brighter (and a few other tweaks) I can replicate the look of other monitors close enough to help prevent washed out/blown out photos. Here is the issue, I need to be able to change settings between the two fairly easily. To manually set my monitor for one then back to the other can be time consuming and a pain to set right every time. I would like to be able to preset certain settings (in software) that I can quickly switch between by pressing hotkeys or clicking shortcut on my desktop. I have an AMD video card and have attempted to use the AMD VISION Engine Control Center to add presets then tweak the settings for each. However when I switch between the presets the settings are the same. How do I build presets using the VISION Engine Control Center that actually works (maybe I misunderstand what it is saving?) or is there a way to do this in Windows 7 or free software that actually works decently for this purpose?

  • How to make Android not to recycle my Bitmap until I don't need it?

    - by RankoR
    I'm getting drawing cache of the view, that is set as contentView to the Activity. Then I set new content view to the activity and pass that drawing cache to it. But Android recycles my bitmaps and I'm getting this exception: 06-13 01:58:04.132: E/AndroidRuntime(15106): java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@40e72dd8 Any way to fix it? I had an idea to extend Bitmap class, but it's final. Why GC is recycling it?

  • add more than 30 days with Calendar's add() method in Java

    - by Haes
    Hi, I'm not quite sure what field to use when adding more than 30 days to a Java Calendar object. Is there any difference in between Calendar.DAY_OF_MONTH and Calendar.DAY_OF_YEAR? Example: GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_YEAR, 90); vs GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_MONTH, 90); Thanks.

  • Django: FloatField or DecimalFied for Currency ?

    - by Hellnar
    I am curious which one would be better fitting as a currency field ? I will do simple operations such as taking difference, the percentage between old and new prices. I plan to keep two digits after the zero (ie 10.50) and majority of the time if these digits are zero, I will be hiding these numbers and display it as "10"

  • clocksource tsc unstable

    Ok, now I have real server fault ;) After some time from booting (about one minute) my server hangs. All I can do is hard reset.

  • Having two IP Routes/Gateways of last Resort on an HP Switch

    - by SteadH
    We have an HP Layer 3 Switch that is doing IP routing between vlans. The general set up is that the switch has an IP address on each VLAN and IP routing is enabled. On our servers VLAN, we have a firewall that has a connection to the outside world. To set a IP route on the HP router, we use IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.1 where 192.168.2.1 is the address of our firewall, and the zeros essentially mean to route all traffic that the switch doesn't know what to do with out the firewall as a gateway. We're in the middle of an ISP and firewall change. I set up the new firewall and ran the IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.254 (the address of the new firewall). Things started working nicely. When I reviewed the configuration of the switch though, I noticed that it did not replace the previous ip route command, but just added another route. Now, I know how to remove the old firewall route (no ip route 0.0.0.0 0.0.0.0 192.168.2.1), but what is the effect of having these two 0.0.0.0 routes? Is it switch implosion? Will a server just respond back over the route it receives the request from? I've read elsewhere that having two default gateways is an impossibility by definition, but I'm curious about this situation that our switch allowed. Thanks!

  • Error 424 from Twitter API

    - by Ted
    I'm experitmenting with the Twitter API (OAuth). I have a test bed that can tweet from my dev box, but fails in production. I get a status code of 424 returned when trying to tweet. I can't spot the difference between my live environment and my dev environment so really need to understand what a '424' is, but can find no documentation relating to it.

  • Why is my number being rounded incorrectly?

    - by izb
    This feels like the kind of code that only fails in-situ, but I will attempt to adapt it into a code snippet that represents what I'm seeing. float f = myFloat * myConstInt; /* Where myFloat==13.45, and myConstInt==20 */ int i = (int)f; int i2 = (int)(myFloat * myConstInt); After stepping through the code, i==269, and i2==268. What's going on here to account for the difference?

  • Creating a Jenkins build farm in a hands-off manner?

    - by user183394
    My colleague and I have set up and run Jenkins on a KVM guest running Ubuntu 12.04 with good results for a while now. We are thinking about deploying a cluster of Jenkins CI hosts in master/slave configuration, with the libvirt slave plugin to keep our hardware count low. Our environment is strictly Linux (CentOS, Scientific Linux, Fedora, and Ubuntu). Both of us are competent in setting up large clusters. We typically use tools like cobbler + a configuration management tool (Puppet, Chef, and alike) to set up a large number of machines (physical and/or virtual) hands off (hundreds of nodes in less than an hour typical). We would like to do the same for nodes running Jenkins. But the step by step guide doesn't give us any clues in this regard. I did see a Multi-slave config plugin. But, being used to dealing with hundreds or more machines completely hands-off, clicking the UI for many machines just doesn't feel right. Can someone point to us a reference that talks about how to set up large cluster of Jenkins CI hosts more in the hands-off way?

  • how to declare a public string with a textbox's text

    - by Ian Lundberg
    i am trying to do public string str = txtText.Text; but it wont let me use txtText.txt so how would I declare that so it can be used everywhere? I can't use it in the button1_click event because if I do it messes it up because I am having a string retrieve from the textbox and set to the textbox so it doesn't work right so I have to have it retrieve the textbox's text somewhere else then set to it.

  • [r] Converting unix seconds in milliseconds to POSIXct/POSIXlt

    - by signalseeker
    Why do I see a difference when I convert a unix timestamp to datetime object in R? > as.POSIXlt(1268736919, origin="1970-01-01", tz="America/New_York") [1] "2010-03-16 06:55:19 EDT" > as.POSIXct(1268736919, origin="1970-01-01", tz="America/New_York") [1] "2010-03-16 11:55:19 EDT" The result from POSIXlt is actually correct. Also, is there a way to do this conversion without specifying the origin? Thanks

  • Rails time zone selector: intelligently selecting a default

    - by Tim Sullivan
    When signing up for an account on one of my apps, we need to store the time zone is in. We're using the time zone selector, which is fine, but I'd like to set the default value to something that it likely the user's current time zone. Is there an easy way, either on the server or using JavaScript, to set the time zone selector to the time zone the user is currently in?

  • Serialize problem with cookie

    - by cagin
    Hi there, I want use cookie in my web project. I must serialize my classes. Although my code can seralize an int or string value, it cant seralize my classes. This is my seralize and cookie code : public static bool f_SetCookie(string _sCookieName, object _oCookieValue, DateTime _dtimeExpirationDate) { bool retval = true; try { if (HttpContext.Current.Request[_sCookieName] != null) { HttpContext.Current.Request.Cookies.Remove(_sCookieName); } BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, _oCookieValue); byte[] bArr = ms.ToArray(); MemoryStream objStream = new MemoryStream(); DeflateStream objZS = new DeflateStream(objStream, CompressionMode.Compress); objZS.Write(bArr, 0, bArr.Length); objZS.Flush(); objZS.Close(); byte[] bytes = objStream.ToArray(); string sCookieVal = Convert.ToBase64String(bytes); HttpCookie cook = new HttpCookie(_sCookieName); cook.Value = sCookieVal; cook.Expires = _dtimeExpirationDate; HttpContext.Current.Response.Cookies.Add(cook); } catch { retval = false; } return retval; } And here is one of my classes: [Serializable] public class Tahlil { #region Props & Fields public string M_KlinikKodu{ get; set; } public DateTime M_AlinmaTarihi { get; set; } private List<Test> m_Tesler; public List<Test> M_Tesler { get { return m_Tesler; } set { m_Tesler = value; } } #endregion public Tahlil() {} Tahlil(DataRow _rwTahlil){} } I m calling my Set Cookie method: Tahlil t = new Tahlil(); t.M_AlinmaTarihi = DateTime.Now; t.M_KlinikKodu = "2"; t.M_Tesler = new List<Test>(); f_SetCookie("Tahlil", t, DateTime.Now.AddDays(1)); I cant see cookie in Cookie folder and Temporary Internet Files but if i will call method like that: f_SetCookie("TRY", 5, DateTime.Now.AddDays(1)); I can see cookie. What is the problem? I dont understand. Thank you for your helps.

  • Multi-tier applications using L2S, WCF and Base Class

    - by Gena Verdel
    Hi all. One day I decided to build this nice multi-tier application using L2S and WCF. The simplified model is : DataBase-L2S-Wrapper(DTO)-Client Application. The communication between Client and Database is achieved by using Data Transfer Objects which contain entity objects as their properties. abstract public class BaseObject { public virtual IccSystem.iccObjectTypes ObjectICC_Type { get { return IccSystem.iccObjectTypes.unknownType; } } [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_ID", AutoSync = AutoSync.OnInsert, DbType = "BigInt NOT NULL IDENTITY", IsPrimaryKey = true, IsDbGenerated = true)] [global::System.Runtime.Serialization.DataMemberAttribute(Order = 1)] public virtual long ID { //get; //set; get { return _ID; } set { _ID = value; } } } [DataContract] public class BaseObjectWrapper<T> where T : BaseObject { #region Fields private T _DBObject; #endregion #region Properties [DataMember] public T Entity { get { return _DBObject; } set { _DBObject = value; } } #endregion } Pretty simple, isn't it?. Here's the catch. Each one of the mapped classes contains ID property itself so I decided to override it like this [global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.Divisions")] [global::System.Runtime.Serialization.DataContractAttribute()] public partial class Division : INotifyPropertyChanging, INotifyPropertyChanged { [global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_ID", AutoSync=AutoSync.OnInsert, DbType="BigInt NOT NULL IDENTITY", IsPrimaryKey=true, IsDbGenerated=true)] [global::System.Runtime.Serialization.DataMemberAttribute(Order=1)] public override long ID { get { return this._ID; } set { if ((this._ID != value)) { this.OnIDChanging(value); this.SendPropertyChanging(); this._ID = value; this.SendPropertyChanged("ID"); this.OnIDChanged(); } } } } Wrapper for division is pretty straightforward as well: public class DivisionWrapper : BaseObjectWrapper<Division> { } It worked pretty well as long as I kept ID values at mapped class and its BaseObject class the same(that's not very good approach, I know, but still) but then this happened: private CentralDC _dc; public bool UpdateDivision(ref DivisionWrapper division) { DivisionWrapper tempWrapper = division; if (division.Entity == null) { return false; } try { Table<Division> table = _dc.Divisions; var q = table.Where(o => o.ID == tempWrapper.Entity.ID); if (q.Count() == 0) { division.Entity._errorMessage = "Unable to locate entity with id " + division.Entity.ID.ToString(); return false; } var realEntity = q.First(); realEntity = division.Entity; _dc.SubmitChanges(); return true; } catch (Exception ex) { division.Entity._errorMessage = ex.Message; return false; } } When trying to enumerate over the in-memory query the following exception occurred: Class member BaseObject.ID is unmapped. Although I'm stating the type and overriding the ID property L2S fails to work. Any suggestions?
