  • Are multiline queries sql-injection safe?

    - by acmatos
    This might be a stupid question. Or maybe my hacking skills are limited (I don't practice them at all). I have a query that looks like this: <?php $query =<<<eot SELECT table_x.field1, table_x.field2, table_y.*, table_z.field4 FROM ( SELECT ... ) as table_y LEFT JOIN table_x ON table_x.field1 = table_y.field_x LEFT JOIN table_z ON table_z.field1 = table_y.field_z WHERE table_x.field3 = '$something' AND table_z.field4 = '1' AND table_z.field5 = '2' eot; ?> I have a lot of other tests on $something before it gets used, like $something = explode(' ',$something); (which later result in a string) none of them intend to prevent injection but they make it hard for the given injection to get as is to the actual query. However, there are ways. We all know how easy it is to replace a space for something else which is still valid.. So, it's not really a problem to make a potentially harmful piece of SQL reach that $something... But is there any way to comment the rest of the original query string if it is multi-line? I can comment AND table_z.field4 = '1' using ;-- but can't comment the following AND table_z.field5 = '2' Is it possible to open a multi-line comment /* without closing it or something looked like and therefore allow the injection to ignore the multi-line query?

  • So, I guess I can't use "&&" in the Python if conditional. What should I use in this case? Any help?

    - by Sergio Tapia
    Here's my code: # F. front_back # Consider dividing a string into two halves. # If the length is even, the front and back halves are the same length. # If the length is odd, we'll say that the extra char goes in the front half. # e.g. 'abcde', the front half is 'abc', the back half 'de'. # Given 2 strings, a and b, return a string of the form # a-front + b-front + a-back + b-back def front_back(a, b): # +++your code here+++ if len(a) % 2 == 0 && len(b) % 2 == 0: return a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):] else: #todo! Not yet done. :P return I'm getting an error in the IF conditional. What am I doing wrong? Edit: I meant no arrogance here. Someone edited my question title to make it sound douchy. I was genuinely confused about what to use, didn't think 'and' would be a keyword. Please don't downvote as other newbies might be confused about it as well.

  • Flash Builder 4 "includeIn" property causing design view error

    - by Chris
    I am creating a custom TextInput component that will define an "error" state. I have extended the TextInput class to change the state to "error" if the errorString property's length is greater than 0. In the skin class, I have defined an "error" state, and added some logic to detect the size and position of the error icon. However, if I have this code at the same time I use the "includeIn" property in the bitmap image tag, I get a design view error. If I either A) Only include that code with no "includeIn" property set, it works or B) dont include the code to set the icon size and position and only use the "includeIn" property, it works. Any ideas what could be causing the design view problem when I use both the "includeIn" property and the icon size/position code at the same time? TextInput Class: package classes { import spark.components.TextInput; public class TextInput extends spark.components.TextInput { [SkinState("error")]; public function TextInput() { super(); } override public function set errorString( value:String ):void { super.errorString = value; invalidateSkinState(); } override protected function getCurrentSkinState():String { if (errorString.length>0) { return "error"; } return super.getCurrentSkinState(); } } } TextInput Skin File: override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { //THIS IS THE CODE THAT SEEMS TO BE CAUSING THE PROBLEM if(getStyle("iconSize") == "large") { errorIcon.right = -12; errorIcon.source = new errorIconLg(); } else { errorIcon.right = -5; errorIcon.source = new errorIconSm(); } super.updateDisplayList(unscaledWidth, unscaledHeight); } </fx:Script> <s:states> <s:State name="normal"/> <s:State name="disabled"/> <s:State name="error"/> </s:states> //If I remove the problem code above or if I take out the includeIn //property here, it works <s:BitmapImage id="errorIcon" verticalCenter="0" includeIn="error" /> </s:SparkSkin>

  • my div tag is not aligning properly after jquery.html replacement

    - by Adam
    <div class="container"><span class="field_label">Job</span><input class="fields2" type="text" maxlength="200" name="first_name" /></div> <div class="container"><span class="field_label">Date</span><input class="fields2" type="text" maxlength="200" name="the_date" id="the_date" /></div> <div class="container" id="sched_text">sdfdsfdsf</div> <!-- schedule text--> <div class="container"><span class="field_label">Time</span> .container{ position:relative; display:block; float:right; border: 1px solid; padding-bottom: 10px; } my html/css here has my containers aligning right below each other. However, when I use .html in jquery to change or add text to sched_text it throws the css off and places the div tag not as a block anymore but placed somewhere to the side. Does something change when you use .html text? what would the proper way of doing it? Thanks Ok the issue is that my .html or .text is not a string. I just did .text(the_Week[i][1]); which results in a number. How do I present it as a string?

  • Which approach is better in term of saving the data? How to handle this?

    - by dewacorp.alliances
    Hi there I have Telerik grid within a Telerik grid. Due to I have a different view between insert and edit mode, so as per suggested I have to use UserControl instead. Inside this control, it could have another Telerik grid plus bunch of ASP.NET textboxes. This thing works well. My dilemma is this: Scenario 1: Handling the save in the user control - OnClick event I have a button to save this. I need to get the value of the "selected grid" so I am using this snippet below and again works well. foreach (GridDataItem dataItem in radgrdTariffNetworkDistributorRateItems.SelectedItems) { string ID = dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex]["SupplierRateItemID"].ToString(); } But then how do I get the id of the parent grid where this control sit? I use the following this event to save: protected void bttnNetworkTariffReviewItemInsert_Click(object sender, EventArgs e) the e of course not the right one though?!?!? GridDataItem parentItem = (GridDataItem)e.Item.OwnerTableView.ParentItem; string reviewID = parentItem.OwnerTableView.DataKeyValues[parentItem.ItemIndex]["ID"].ToString(); Scenario 2: Handling the save in the page instead (OnInsertCommand on the master grid) With this approach works well to get id of the grid etc BUT I am having a problem to get selected grid in the UserControl and plus couple controls value. How do I make this feasible? Logically, I should handle this at the user control level to save but again because the user control relying on the child grid I am having trouble to get this value. I am appreciated your suggestion.

  • Is there any good reason for private methods existence in C# (and OOP in general)?

    - by Piotr Lopusiewicz
    I don't mean to troll but I really don't get it. Why would language designers allow private methods instead of some naming convention (see __ in Python) ? I searched for the answer and usual arguments are: a) To make the implementation cleaner/avoid long vertical list of methods in IDE autocompletion b) To announce to the world which methods are public interface and which may change and are just for implementation purpose c) Readability Ok so now, all of those could be achieved by naming all private methods with __ prefix or by "private" keyword which doesn't have any implications other than be information for IDE (don't put those in autocompletion) and other programers (don't use it unless you really must). Hell, one could even require unsafe-like keyword to access private methods to really discourage this. I am asking this because I work with some c# code and I keep changing private methods to public for test purposes as many in-between private methods (like string generators for xml serialization) are very useful for debugging purposes (like writing some part of string to log file etc.). So my question is: Is there anything which is achieved by access restriction but couldn't be achieved by naming conventions without restricting the access ?

  • Silverlight Export Datagrid to Excel (without roundtrip)

    - by kirkktx
    I've got a silverlight 2 app with a Datagrid and a button for exporting it to Excel by making a trip back to the server. I can create an HTML string representing the datagrid. I'd like to attach this string to an html element, setting MIME type=application/vnd.ms-excel and have a prompt show up asking if I'd like to open or save the xls file. After all if ASP can do this ... <% The main feature of this technique is that %> <% you have to change Content type to ms-excel.%> Response.ContentType = "application/vnd.ms-excel" <TABLE> <TR><TD>2</TD></TR> <TR><TD>3</TD></TR> <TR><TD>=SUM(A1:A2)</TD></TR> </TABLE> ... it seems like I should be able to do something similar from within Silverlight, pushing it onto the HTML DOM. Any suggestions greatly appreciated!

  • Extending abstract classes in c#

    - by ng
    I am a Java developer and I have noticed some differences in extending abstract classes in c# as opposed to Java. I was wondering how a c# developer would achived the following. 1) Covarience public abstract class A { public abstract List<B> List(); } public class BList : List<T> where T : B { } public abstract class C : A { public abstract BList List(); } So in the above hierarchy, there is covarience in C where it returns a type compatible with what A returns. However this gives me an error in Visual Studio. Is there a way to specify a covarient return type in c#? 2) Adding a setter to a property public abstract class A { public abstract String Name { get; } } public abstract class B : A { public abstract String Name { get; set } } Here the compiler complains of hiding. Any suggestions? Please do not suggest using interfaces unless that is the ONLY way to do this.

  • Credit card validation with regexp using test()

    - by Matt
    I'm trying to complete some homework and it appears the book might have gotten it wrong. I have a simple html page that allows user to pick a credit card in our case american express. The user then enters a number and evalutes that number based on a regular expression. My question ends up being when test() evaluates the number it returns a boolean or a string? I should then compare that string or boolean? True == true should fire off the code in a nested if statement. Heres what the book gives me as valid code: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE if(cardProtocol.test(document.forms[0].cardNumber.value)) document.forms[0].ccResult.value = "Valid credit card number"; } The above code doesn't work in firefox. I've tried modifying it with 2 alerts to make sure the number is good and the boolean is good...and still no luck: if(document.forms[0].cardName.value == "American Express") { var cardProtocol = new RegExp("^3[47][0-9]{13}$"); //REGEX ENTRY HERE <------ alert(document.forms[0].cardNumber.value) alert(cardProtocol.test(document.forms[0].cardNumber.value)) if((cardProtocol.test(document.forms[0].cardNumber.value)) == true ) // <--Problem { document.forms[0].ccResult.value = "Valid credit card number"; } else { document.forms[0].ccResult.value = "Invalid credit card number"; } } Any ideas? the if loop is the culprit but I'm not figuring out why it is not working. Please throw up the code for the if loop! Thanks for the help!

  • Is there such a thing as a MemberExpression that handles a many-to-many relationship?

    - by Jaxidian
    We're trying to make it easy to write strongly-typed code in all areas of our system, so rather than setting var sortColumn = "FirstName" we'd like to say sortOption = (p => p.FirstName). This works great if the sortOption is of type Expression<Func<Person, object>> (we actually use generics in our code but that doesn't matter). However, we run into problems for many-to-many relationships because this notation breaks down. Consider this simple code: internal class Business { public IQueryable<Address> Addresses { get; set; } public string Name { get; set; } } internal class Address { public State MyState { get; set; } } internal class State { public string Abbreviation { get; set; } public int StateID { get; set; } } Is it possible to have this sort of MemberExpression to identify the StateID column off of a business? Again, the purpose of using this is not to return a StateID object, it's to just identify that property off of that entity (for sorting, filtering, and other purposes). It SEEMS to me that there should be some way to do this, even if it's not quite as pretty as foo = business.Addresses.SomeExtension(a => a.State.StateID);. Is this really possible? If more background is needed, take a look at this old question of mine. We've since updated the code significantly, but this should give you the general detailed idea of the context behind this question.

  • Changing commas within quotes

    - by user1822739
    I am trying to read the data in a text file which is separated by commas. My problem, is that one of my data pieces has a comma within it. An example of what the text file looks like is: a, b, "c, d", e, f. I want to be able to take the comma between c and d and change it to a semicolon so that I can still use the string.Split() method. using (StreamReader reader = new StreamReader("file.txt")) { string line; while ((line = reader.ReadLine ()) != null) { bool firstQuote = false; for (int i = 0; i < line.Length; i++) { if (line [i] == '"' ) { firstQuote = true; } else if (firstQuote == true) { if (line [i] == '"') { break; } if ((line [i] == ',')) { line = line.Substring (0, i) + ";" + line.Substring (i + 1, (line.Length - 1) - i); } } } Console.WriteLine (line); } } I am having a problem. Instead of producing a, b, "c; d", e, f, it is producing a, b, "c; d"; e; f. It is replacing all of the following commas with semicolons instead of just the comma in the quotes. Can anybody help me fix my existing code?

  • Using overloaded operator== in a generic function

    - by Dimitri C.
    Consider the following code: class CustomClass { public CustomClass(string value) { m_value = value; } public static bool operator==(CustomClass a, CustomClass b) { return a.m_value == b.m_value; } public static bool operator!=(CustomClass a, CustomClass b) { return a.m_value != b.m_value; } public override bool Equals(object o) { return m_value == (o as CustomClass).m_value; } public override int GetHashCode() { return 0; /* not needed */ } string m_value; } class G { public static bool enericFunction1<T>(T a1, T a2) where T : class { return a1.Equals(a2); } public static bool enericFunction2<T>(T a1, T a2) where T : class { return a1==a2; } } Now when I call both generic functions, one succeeds and one fails: var a = new CustomClass("same value"); var b = new CustomClass("same value"); Debug.Assert(G.enericFunction1(a, b)); // Succeeds Debug.Assert(G.enericFunction2(a, b)); // Fails Apparently, G.enericFunction2 executes the default operator== implementation instead of my override. Can anybody explain why this happens?

  • Calling child constructor by casting (ChildClass)parentObject; to track revisions

    - by FreshCode
    To track revisions of a Page class, I have a PageRevision class which inherits from Page and adds a revision ID (Guid RevisionID;). If possible, how should I cast an existing Page object to a PageRevision and ensure that the PageRevision constructor is called to create a new revision ID? I could could have a PageRevision(Page page) constructor which generates the Guid and copies all the Page attributes, but I want to automate it, especially if a Page class has many attributes (and I later add one, and forget to modify the copy constructor). Desired use Page page = new Page(123, "Page Title", "Page Body"); // where 123 is page ID PageRevision revision = (PageRevision)page; // now revision.RevisionID should be a new Guid. Page, PageRevision classes: public class Page { public int ID { get; set; } public string Title { get; set; } public string Body { get; set; } } public class PageRevision : Page { public Guid RevisionID { get; set; } public PageRevision() { this.RevisionID = Guid.NewGuid(); } }

  • NSPredicate (Core Data fetch) to filter on an attribute value being present in a supplied set (list)

    - by starbaseweb
    I'm trying to create a fetch predicate that is the analog to the SQL "IN" statement, and the syntax to do so with NSPredicate escapes me. Here's what I have so far (the relevant excerpt from my fetching routine): NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *entity = [NSEntityDescription entityForName: @"BodyPartCategory" inManagedObjectContext:_context]; [request setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(name IN %@)", [RPBodyPartCategory defaultBodyPartCategoryNames]]; [request setPredicate:predicate]; The entity "BodyPartCategory" has a string attribute "name". I have a list of names (just NSString objects) in an NSArray as returned by: [RPBodyPartCategory defaultBodyPartCategoryNames] So let's say that array has string such as {@"Liver", @"Kidney", @"Thyroid"} ... etc. I want to fetch all 'BodyPartCategory' instances whose name attribute matches one of the strings in the set provided (technically NSArray but I can make it an NSSet). In SQL, this would be something like: SELECT * FROM BodyPartCategories WHERE name IN ('Liver', 'Kidney', 'Thyroid') I've gone through various portions of the Predicate Programming Guide, but I don't see this simple use case covered. Pointers/help much appreciated!

  • Cannot understand the behaviour of C# compiler while instantiating a class thru interface

    - by Newbie
    I have a class that implements an interface. The interface is public interface IRiskFactory { void StartService(); void StopService(); } The class that implements the interface is public class RiskFactoryService : IRiskFactory { } Now I have a console application and one window service. From the console application if I write the following code static void Main(string[] args) { IRiskFactory objIRiskFactory = new RiskFactoryService(); objIRiskFactory.StartService(); Console.ReadLine(); objIRiskFactory.StopService(); } It is working fine. However, when I mwrite the same piece of code in Window service public partial class RiskFactoryService : ServiceBase { IRiskFactory objIRiskFactory = null; public RiskFactoryService() { InitializeComponent(); objIRiskFactory = new RiskFactoryService(); <- ERROR } /// <summary> /// Starts the service /// </summary> /// <param name="args"></param> protected override void OnStart(string[] args) { objIRiskFactory.StartService(); } /// <summary> /// Stops the service /// </summary> protected override void OnStop() { objIRiskFactory.StopService(); } } It throws error: Cannot implicitly convert type 'RiskFactoryService' to 'IRiskFactory'. An explicit conversion exists (are you missing a cast?) When I type cast to the interface type, it started working objIRiskFactory = (IRiskFactory)new RiskFactoryService(); My question is why so?

  • C# Possible to have a generic return type?

    - by JL
    Here is a typical function that returns either true/false; private static bool hasValue() { return true; } Now on an error, I would like to return my own custom error object with definition: public class Failure { public string failureDateTime { get; set; } public string failureReason { get; set; } } I would have expected to be able to throw this custom object for example... private static bool hasValue() { throw new Failure(); } This is not possible, and I don't want to derive Failure from System.IO.Exception because of the inability to serialize an exception in C#. What is the best practice / or ideal solution to this problem. Should I just work with private static object? Or is there a cleaner way to return a custom object or bypass the typical return type on an error (not using System.IO.Exception)? Not entirely wild about object either, because then I need to cast the result and validate it by more boolean logic.

  • Trying to overload + operator

    - by FrostyStraw
    I cannot for the life of me understand why this is not working. I am so confused. I have a class Person which has a data member age, and I just want to add two people so that it adds the ages. I don't know why this is so hard, but I'm looking for examples and I feel like everyone does something different, and for some reason NONE of them work. Sometimes the examples I see have two parameters, sometimes they only have one, sometimes the parameters are references to the object, sometimes they're not, sometimes they return an int, sometimes they return a Person object. Like..what is the most normal way to do it? class Person { public: int age; //std::string haircolor = "brown"; //std::string ID = "23432598"; Person(): age(19) {} Person operator+(Person&) { } }; Person operator+(Person &obj1, Person &obj2){ Person sum = obj1; sum += obj2; return sum; } I really feel like overloading a + operator should seriously be the easiest thing in the world except I DON'T KNOW WHAT I AM DOING. I don't know if I'm supposed to create the overload function inside the class, outside, if it makes a difference, why if I do it inside it only allows one parameter, I just honestly don't get it.

    I have an Activity with a WeView that load an url, and I want to display a little waiting dialog during the load of the site, so I have tried this: private ProgressDialog dialog = new ProgressDialog(MyNameActivity.this); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() .permitAll().build(); StrictMode.setThreadPolicy(policy); setContentView(R.layout.web_view_activity); WebView wv; wv = (WebView) findViewById(R.id.areaWebSolver); wv.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } @Override public void onPageFinished(WebView view, String url) { if (dialog.isShowing()) { dialog.dismiss(); } } }); dialog.setMessage("Loading..Please wait."); dialog.setCanceledOnTouchOutside(false); dialog.show(); wv.loadUrl(url); WebSettings webSettings = wv.getSettings(); webSettings.setJavaScriptEnabled(true); } Unfortunately doesn't works and the app crashes with a source not found... If I try to remove the Progress dialog code the activity works. What's wrong? How could I fix this?

  • C# how to get trailing spaces from the end of a varchar(513) field while exporting SQL table to a fl

    - by svon
    How do I get empty spaces from the end of a varchar(513) field while exporting data from SQL table to a flat file. I have a console application. Here is what I am using to export a SQL table having only one column of varchar(513) to a flat file. But I need to get all the 513 characters including spaces at the end. How do I change this code to incorporate that. Thanks { var destination = args[0]; var command = string.Format("Select * from {0}", Validator.Check(args[1])); var connectionstring = string.Format("Data Source={0}; Initial Catalog=dbname;Integrated Security=SSPI;", args[2]); var helper = new SqlHelper(command, CommandType.Text, connectionstring); using (StreamWriter writer = new StreamWriter(destination)) using (IDataReader reader = helper.ExecuteReader()) { while (reader.Read()) { Object[] values = new Object[reader.FieldCount]; int fieldCount = reader.GetValues(values); for (int i = 0; i < fieldCount; i++) writer.Write(values[i]); writer.WriteLine(); } writer.Close(); }
