  • django+uploadify - don't working

    - by Erico
    Hi, I'm trying to use an example posted on the "github" the link is http://github.com/tstone/django-uploadify. And I'm having trouble getting work. can you help me? I followed step by step, but does not work.

  • How to call RequiredFieldValidator on client before postback

    - by Si
    I've inherited some code which breaks a page up into tabs using divs. On the first page there are many required field and regex validators. The problem is a user can switch to another tab, trigger a postback and fail the validators on the first page, leaving things in a mess. What I want to be able to do is perform the validation on the first page as a user selects another tab, thus preventing them from moving to a new tab until the first page is valid. <ul> <li><a href="#tab1">Tab 1</a> </li> <li><a href="#tab2" onclick="return isValid();">Tab 2</a></li> <li><a href="#tab3" onclick="return isValid();">Tab 3</a></li> </ul> Where isValid needs to fire off the validators. Thanks!

  • ASP.Net Entity Framework, objectcontext error

    - by Chris Klepeis
    I'm building a 4 layered ASP.Net web application. The layers are: Data Layer Entity Layer Business Layer UI Layer The entity layer has my data model classes and is built from my entity data model (edmx file) in the datalayer using T4 templates (POCO). The entity layer is referenced in all other layers. My data layer has a class called SourceKeyRepository which has a function like so: public IEnumerable<SourceKey> Get(SourceKey sk) { using (dmc = new DataModelContainer()) { var query = from SourceKey in dmc.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query; } } Lazy loading is disabled since I do not want my queries to run in other layers of this application. I'm receiving the following error when attempting to access the information in the UI layer: The ObjectContext instance has been disposed and can no longer be used for operations that require a connection. I'm sure this is because my DataModelContainer "dmc" was disposed. How can I return this IEnumerable object from my data layer so that it does not rely on the ObjectContext, but solely on the DataModel? Is there a way to limit lazy loading to only occur in the data layer?

  • issues make a persistent object in Objective C

    - by oden
    Attempting to make a NSObject called 'Person' that will hold the login details for my application (nothing to fancy). The app is made of a navigation controller with multiple table views but I am having issues sharing the Person object around. Attempted to create a static object like this: + (Person *)sharedInstance { static Person *sharedInstance; @synchronized(self) { if(!sharedInstance) sharedInstance = [[Person alloc] init]; return sharedInstance; } return nil; } And here is the header // Person.h #import <Foundation/Foundation.h> @interface Person : NSObject { NSString *fullName; NSString *firstName; NSString *lastName; NSString *mobileNumber; NSString *userPassword; } @property(nonatomic, retain) NSString *fullName; @property(nonatomic, retain) NSString *firstName; @property(nonatomic, retain) NSString *lastName; @property(nonatomic, retain) NSString *mobileNumber; @property(nonatomic, retain) NSString *userPassword; + (Person *)sharedInstance; -(BOOL) setName:(NSString*) fname; -(BOOL) setMob:(NSString*) mnum; -(BOOL) setPass:(NSString*) pwd; @end This object setters and getters are needed in different parts of the application. I have been attempting to access them like this Person * ThePerson = [[Person alloc] init]; ThePerson = nil; NSString * PersonsName; PersonsName = [[Person sharedInstance] firstName]; Everything works well at the login screen but it dies at the next use. usually EXC_BAD_ACCESS (eek!). Clearly I am doing something very wrong here. Is there an easier way to share objects between different a number view controllers (both coded and xib)?

  • Pause code execution until UIAlertView button is pressed?

    - by JuBu1324
    One of my methods sends a message to an object (what do you know about that), and expects a BOOL for an answer. However, BOOL answer it is expecting is based on the answer to a UIAlertView created in the receiving object's method. However, the code doesn't pause while waiting for the user to answer the UIAlertView. My problem is: how do I use -alertView:clickedButtonAtIndex in the method's return value? Here's the code the message runs (in this construction, I was expecting navigateAwayFromTab to change based on the user input in the UIAlertView, but it never gets a chance): - (BOOL)readyToNavigateAwayFromTab { NSLog( @"message received by Medical View"); navigateAwayFromTab = NO; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Navigate Away From Tab?" message:@"Navigating away from this tab will save your work." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil ]; [alert show]; [alert release]; return navigateAwayFromTab; } #define CANCEL 0 #define OK 1 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if( buttonIndex == OK ) navigateAwayFromTab = YES; } I've been reading up on the modal UIAlertView debate, and I agree with apple's implementation - at lest as the rule. However, in this case I don't see any way of solving the problem by putting code in -alertView:clickedButtonAtIndex because I don't need to run code based on the UIAlertView, I just need to read the response. Any suggestions on how I can reach my gaol? I've tried a while loop after [alert show] already, but then the alert doesn't even show then, and for a number of reasons I can't use -viewWillDisapear.

  • calling CreateFile, specifying FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE.

    - by alexander-daniels
    Before I describe my problem, here is a description of the program I'm writting: This is a C++ application. The purpose of my program is to create file on RAM memory. I read that if specify FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE when creating file it will be loaded direct to the RAM memory. One of blogs that talk about is this one: http://blogs.msdn.com/larryosterman/archive/2004/04/19/116084.aspx I have built a mini-program, but it not achieves the goal. Instead, it creates a file on hard-drive on directory I specify. Here's my program: void main () { LPCWSTR str = L"c:\temp.txt"; HANDLE fh = CreateFile(str,GENERIC_WRITE,0,NULL,CREATE_ALWAYS, FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE,NULL); if (fh == INVALID_HANDLE_VALUE) { printf ("Could not open TWO.TXT"); return; } DWORD dwBytesWritten; for (long i=0; i<20000000; i++) { WriteFile(fh, "This is a test\r\n", 16, &dwBytesWritten, NULL); } return; } I think there problem in CreateFile function, but I can't fix it. Please help me.

  • Silverlight ComboBox Attached Behavior

    - by Mark Cooper
    I am trying to create an attached behavior that can be applied to a Silverlight ComboBox. My behavior is this: using System.Windows.Controls; using System.Windows; using System.Windows.Controls.Primitives; namespace AttachedBehaviours { public class ConfirmChangeBehaviour { public static bool GetConfirmChange(Selector cmb) { return (bool)cmb.GetValue(ConfirmChangeProperty); } public static void SetConfirmChange(Selector cmb, bool value) { cmb.SetValue(ConfirmChangeProperty, value); } public static readonly DependencyProperty ConfirmChangeProperty = DependencyProperty.RegisterAttached("ConfirmChange", typeof(bool), typeof(Selector), new PropertyMetadata(true, ConfirmChangeChanged)); public static void ConfirmChangeChanged(DependencyObject d, DependencyPropertyChangedEventArgs args) { Selector instance = d as Selector; if (args.NewValue is bool == false) return; if ((bool)args.NewValue) instance.SelectionChanged += OnSelectorSelectionChanged; else instance.SelectionChanged -= OnSelectorSelectionChanged; } static void OnSelectorSelectionChanged(object sender, RoutedEventArgs e) { Selector item = e.OriginalSource as Selector; MessageBox.Show("Unsaved changes.

  • Finding duplicate rows in SQL Server

    - by xtine
    I have a SQL Server database of organizations, and there are many duplicate rows. I want to run a select statement to grab all of these and the amount of dupes, but also return the ids that are associated with each organization. A statement like: SELECT orgName, COUNT(*) AS dupes FROM organizations GROUP BY orgName HAVING (COUNT(*) > 1) Will return something like orgName | dupes ABC Corp | 7 Foo Federation | 5 Widget Company | 2 But I'd also like to grab the IDs of them. Is there any way to do this? Maybe like a orgName | dupeCount | id ABC Corp | 1 | 34 ABC Corp | 2 | 5 ... Widget Company | 1 | 10 Widget Company | 2 | 2 The reason being that there is also a separate table of users that link to these organizations, and I would like to unify them (therefore remove dupes so the users link to the same organization instead of dupe orgs). But I would like part manually so I don't screw anything up, but I would still need a statement returning the IDs of all the dupe orgs so I can go through the list of users. Any help would be greatly appreciated. Thanks :)

  • iPhone: CoreGraphics and memory management

    - by carloe
    Can someone tell me what I am doing wrong here? I use this method to flip through pages in a PDF. But something in the code seems to not be released properly because every-time I pull a PDF page that contains an image my memory footprint increases. I am fairly new to CoreGraphics, and can't for the life of me figure out where this method would leak memory. -(UIImage *)pageAtIndex:(NSInteger)pageNumber withWidth:(CGFloat)width andHeight:(CGFloat)height { if((pageNumber>0) && (pageNumber<=pageCount)) { CGFloat scaleRatio; // multiplier by which the PDF Page will be scaled UIGraphicsBeginImageContext(CGSizeMake(width, height)); CGContextRef context = UIGraphicsGetCurrentContext(); CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber); CGRect pageRect = CGPDFPageGetBoxRect(page, kCGPDFBleedBox); //Figure out the orientation of the PDF page and set the scaleRatio accordingly if(pageRect.size.width/pageRect.size.height < 1.0) { scaleRatio = height/pageRect.size.height; } else { scaleRatio = width/pageRect.size.width; } //Calculate the offset to center the image CGFloat xOffset = 0.0; CGFloat yOffset = height; if(pageRect.size.width*scaleRatio<width) { xOffset = (width/2)-(pageRect.size.width*scaleRatio/2); } else { yOffset = height-((height/2)-(pageRect.size.height*scaleRatio/2)); } CGContextTranslateCTM(context, xOffset, yOffset); CGContextScaleCTM(context, 1.0, -1.0); CGContextSaveGState(context); CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFBleedBox, CGRectMake(0, 0, pageRect.size.width, pageRect.size.height), 0, true); pdfTransform = CGAffineTransformScale(pdfTransform, scaleRatio, scaleRatio); CGContextConcatCTM(context, pdfTransform); CGContextDrawPDFPage(context, page); UIImage *tempImage = [UIGraphicsGetImageFromCurrentImageContext() retain]; CGContextRestoreGState(context); UIGraphicsEndPDFContext(); UIGraphicsEndImageContext(); return tempImage; } return nil; }

  • Getting Oracle's MD5 to match PHP's MD5

    - by Zenshai
    Hi all, I'm trying to compare an MD5 checksum generated by PHP to one generated by Oracle 10g. However it seems I'm comparing apples to oranges. Here's what I did to test the comparison: //md5 tests //php md5 print md5('testingthemd5function'); print '<br/><br/>'; //oracle md5 $md5query = "select md5hash('testingthemd5function') from dual"; $stid = oci_parse($conn, $md5query); if (!$stid) { $e = oci_error($conn); print htmlentities($e['message']); exit; } $r = oci_execute($stid, OCI_DEFAULT); if (!$r) { $e = oci_error($stid); echo htmlentities($e['message']); exit; } $row = oci_fetch_row($stid); print $row[0]; The md5 function (seen in the query above) in Oracle uses the 'dbms_obfuscation_toolkit.md5' package(?) and is defined like this: CREATE OR REPLACE FUNCTION PORTAL.md5hash (v_input_string in varchar2) return varchar2 is v_checksum varchar2(20); begin v_checksum := dbms_obfuscation_toolkit.md5 (input_string => v_input_string); return v_checksum; end; What comes out on my PHP page is: 29dbb90ea99a397b946518c84f45e016 )Û¹©š9{”eÈOEà Can anyone help me in getting the two to match?

  • Swig typecast to derived class?

    - by Zack
    I notice that Swig provides a whole host of functions to allow for typecasting objects to their parent classes. However, in C++ one can produce a function like the following: A * getAnObject() { if(someBoolean) return (A *) new B; else return (A *) new C; } Where "A" is the parent of classes "B" and "C". One can then typecast the pointer returned into being a "B" type or "C" type at one's convenience like: B * some_var = (B *) getAnObject(); Is there some way I can typecast an object I've received from a generic-pointer-producing function at run-time in the scripting language using the wrappers? (In my case, Lua?) I have a function that could produce one of about a hundred possible classes, and I'd like to avoid writing an enormous switch structure that I'd have to maintain in C++. At the point where I receive the generic pointer, I also have a string representation of the data type I'd like to cast it to. Any thoughts? Thanks! -- EDIT -- I notice that SWIG offers to generate copy constructors for all of my classes. If I had it generate those, could I do something like the following?: var = myModule.getAnObject(); -- Function that returns an object type-cast down to a pointer of the parent class, as in the function getAnObject() above. var = myModule.ClassThatExtendsBaseClass(var); -- A copy constructor that SWIG theoretically creates for me and have var then be an instance of the inheriting class that knows it's an instance of the inheriting class?

  • How can I create a generaic ValidationAttribute in C#?

    I'm trying to create a UniqueAttribute using the System.ComponentModel.DataAnnotations.ValidationAttribute I want this to be generic as in I could pass the Linq DataContext, the table name, the field and validate if the incoming value is unique or not.

  • How do you handle 'SelectedItemChanged' events in a MVVM ViewModel?

    - by Travis
    I have some logic that depends upon two properties being set, as it executes when both properties have a value. For example: private void DoCalc() { if (string.IsNullOrEmpty(Property1) || string.IsNullOrEmpty(Property2)) return; Property3 = Property1 + " " + Property2; } That code would need to be executed every time Property1 or Property2 changed, but I'm having trouble figuring out how to do it in a stylistically acceptable manner. Here are the choices as I see them: 1) Call method from ViewModel I don't have a problem with this conceptually, as the logic is still in the ViewModel - I'm not a 'No code-behind' nazi. However, the 'trigger' logic (when either property changes) is still in the UI layer, which I don't love. The codebehind would look like this: void ComboBox_Property1_SelectedItemChanged(object sender, RoutedEventArgs e) { viewModel.DoCalc(); } 2) Call method from Property Setter This approach seems the most 'pure', but it also seems ugly, as if the logic is hidden. It would look like this: public string Property1 { get {return property1;} set { if (property1 != value) { property1 = value; NotifyPropertyChanged("Property1"); DoCalc(); } } } 3) Hook into the PropertyChanged event I'm now thinking this might be the right approach, but it feels weird to hook into the property changed event in the implementing viewmodel. It would look something like this: public ViewModel() { this.PropertyChanged += new PropertyChangedEventHandler(ViewModel_PropertyChanged); } void ViewModel_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "Property1" || e.PropertyName == "Property2") { DoCalc(); } } So, my question is, if you were browsing through some source code with that requirement, which approach would you prefer to see implemented (and why?). Thanks for any input.

  • How can I get PowerShell Added-Types to use Added Types

  • Fetch and bulk collect from a REF CURSOR returned by a procedure

    - by Rachcha
    I have a procedure that has a SYS_REFCURSOR as an OUT parameter. The signature is, for example, as follows: PROCEDURE myProc(p_someID IN INTEGER, p_cursor OUT SYS_REFCURSOR); I call this procedure from a function, where I have to copy a column named clientID from the p_cursor to a scalar nested table. I am doing as follows: CREATE OR REPLACE FUNCTION myFunction RETURN sys_refcursor IS someID INTEGER := 1234; myCursor SYS_REFCURSOR; TYPE t_clientID_nt IS TABLE OF NUMBER(16,0); clientID_nt t_clientID_nt; otherID SYS_REFCURSOR; BEGIN myProc (someID, myCursor); FOR i IN myCursor LOOP clientID_nt.EXTEND; clientID_nt (clientID_nt.COUNT) := i.clientID; END LOOP; -- Other code that opens the cursor otherID -- based on the IDs in clientID_nt ... ... RETURN otherID; END; / When I try to compile this function, the error I get is: PLS-00221: 'CLIENTID_NT' is not a procedure or is undefined and it is at line 11 of the code. Any help on how to fetch and bulk collect from such a cursor is greatly appreciated.

  • Generate BitmapSource from UIElement

    - by Joel
    I am attempting to generate a BitmapFrame that is based on a UIElement. Here is my function: private BitmapFrame RenderToBitmap2() { RenderTargetBitmap renderBitmap = new RenderTargetBitmap(200, 200, 96, 96, PixelFormats.Pbgra32); DrawingVisual drawingVisual = new DrawingVisual(); DrawingContext drawingContext = drawingVisual.RenderOpen(); VisualBrush aVisualBrush = new VisualBrush(GenerateTestStackPanel()); drawingContext.DrawRectangle(aVisualBrush, new Pen(Brushes.Green, 2), new Rect(new Size(150, 150))); drawingContext.Close(); renderBitmap.Render(drawingVisual); return BitmapFrame.Create(renderBitmap); } For testing and debugging purposes, I am using an additional function that creates a simple StackFrame that should create a valid visual element that can be represented: private StackPanel GenerateTestStackPanel() { // Create a red Ellipse. Ellipse myEllipse = new Ellipse(); myEllipse.Fill = Brushes.Green; myEllipse.StrokeThickness = 2; myEllipse.Stroke = Brushes.Black; // Set the width and height of the Ellipse. myEllipse.Width = 200; myEllipse.Height = 200; // Add the Ellipse to the StackPanel. StackPanel myStackPanel = new StackPanel(); myStackPanel.Children.Add(myEllipse); return myStackPanel; } For some reason, the VisualBrush is not being rendered in the DrawRetangle(...) function. I can see the green border but nothing else. In addition, if I swap out the VisualBrush with a standard brush, it works great: drawingContext.DrawRectangle(Brushes.Plum, new Pen(Brushes.Green, 2), new Rect(new Size(150, 150))); Thanks in advance! -Joel

  • How to get rank from full-text search query with Linq to SQL?

    - by Stephen Jennings
    I am using Linq to SQL to call a stored procedure which runs a full-text search and returns the rank plus a few specific columns from the table Article. The rank column is the rank returned from the SQL function FREETEXTTABLE(). I've added this sproc to the data model designer with return type Article. This is working to get the columns I need; however, it discards the ranking of each search result. I'd like to get this information so I can display it to the user. So far, I've tried creating a new class RankedArticle which inherits from Article and adds the column Rank, then changing the return type of my sproc mapping to RankedArticle. When I try this, an InvalidOperationException gets thrown: Data member 'Int32 ArticleID' of type 'Heap.Models.Article' is not part of the mapping for type 'RankedArticle'. Is the member above the root of an inheritance hierarchy? I can't seem to find any other questions or Google results from people trying to get the rank column, so I'm probably missing something obvious here.

  • long delay between serverside JSON and jqGrid loadComplete on asp.net mvc site

    - by ooo
    i have an asp.net mvc site where i load a jqgrid with json data public ActionResult GridData(GridData args) { IEnumerable<Application> applications = EntityModel.GetAll().ToList(); applications = FilterEntities(applications); if (args.sidx.IsNullOrEmpty() || args.sidx == "Id") { args.sidx = "Name"; args.sord = "asc"; } applications = applications.GridSort(args.sidx, args.sord); var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10, i => new { i.Id, Name = "<div class='showDescription' Id= '" + i.MyId + "'>" + i.Name + "</div>", MyId = string.Format("<a i.LastUpdated, i.LastUpdatedColumn }); return Json(paginatedData); } and here is my javascript code: function doInitCrudGrid(controller, names, model, editable, querystring) { jQuery("#grid").jqGrid({ mtype: 'POST', url: "/" + controller + "/GridData?" + querystring, datatype: "json", colNames: names, colModel: model, imgpath: "/Scripts/jqGrid/themes/steel/images", rowNum: 20, rowList: [10, 20, 50, 999], altRows: true, altclass: "altRow", jsonReader: { root: "Rows", page: "Page", total: "Total", records: "Records", repeatitems: false, id: "Id" }, pager: "#pager", height: "auto", sortname: "Id", viewrecords: true, sortorder: "desc", loadComplete: function() { alert("Load Complete"); }, ondblClickRow: function(rowid) { } }); i have a breakpoint on the return Json(paginatedData); line and that gets hit very quick but after that it takes about 10 seconds for the: alert("Load Complete"); and for the rendering to show up on the web page. Is there anyway to debug this or way to see why there would be this large delay between finishing the server side json and histting the loadcomplete on the javascript callback ?

  • Subsonic 3, MySql, won't update record.

    [WebMethod] public string GetAuthToken(string username, string password) { var db = new LogicDB(); //var results = from u in db.Users // where u.Username == username && u.Password == password // select u; User u = db.Select .From<User>() .Where(UsersTable.UsernameColumn).IsEqualTo(username) .And(UsersTable.PasswordColumn).IsEqualTo(password) .ExecuteSingle<User>(); if (u == null) { return "{'success': false, 'reason': 'Invalid username and/or password.'}"; } else { // really there should only be one match...

This is when u.Save(db.Provider); is uncommented. And happens even with just u.Save(); or using the linq query above results instead.

  • silverlight master-detail with two listboxes in pure xaml with ria services throwing exception

    - by Sam
    Hi, I was trying to achieve master-detail with 2 ListBox, 2 DomainDataSource and a IValueConverter, when entering the page it throws the random error it does when your xaml is invalid: "AG_E_PARSER_BAD_PROPERTY_VALUE [Line: 24 Position: 61]" Which is in fact the start position of where I am binding the listbox selected item with converter to the parameter's value of my DomainDataSource. I would love to achieve this by pure xaml, I did it by code behind and that works but I don't like it :p When the parameter is a hard-coded integer 1, it works, so I assume it's the value binding My code is below here, thanks in advance for at least looking :) (taken into accound all the xmlns's & usings are correct) Xaml: <Grid x:Name="LayoutRoot"> <Grid.Resources> <helpers:ListItemtoIdListValueConverter x:Key="mListConverter" /> </Grid.Resources> <riacontrols:DomainDataSource x:Name="GetLists" DomainContext="{StaticResource DbContext}" LoadSize="20" QueryName="GetLists" AutoLoad="True" /> <riacontrols:DomainDataSource x:Name="GetListItems" DomainContext="{StaticResource DbContext}" LoadSize="20" QueryName="GetListItemsById" AutoLoad="True"> <riacontrols:DomainDataSource.QueryParameters> <riadata:Parameter ParameterName="id" Value="{Binding ElementName=ListBoxLists, Path=SelectedItem, Converter={StaticResource mListConverter}}" /> </riacontrols:DomainDataSource.QueryParameters> </riacontrols:DomainDataSource> <activity:Activity IsActive="{Binding IsBusy, ElementName=ListBoxListItems}"> <StackPanel Orientation="Horizontal"> <ListBox x:Name="ListBoxLists" ItemsSource="{Binding Data, ElementName=GetLists, Mode=OneWay}" Width="150" Margin="0,0,10,10" /> <ListBox x:Name="ListBoxListItems" ItemsSource="{Binding Data, ElementName=GetListItems, Mode=OneWay}" Width="150" Margin="0,0,10,10" /> </StackPanel> </activity:Activity> </Grid> IValueConverter: public class ListItemtoIdListValueConverter: IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { list mList = (list)value; if (mList != null) return mList.id; else return null; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion }

  • InvalidOperationException (Lambda parameter not in scope) when trying to Compile a Lambda Expression

    - by Moshe Levi
    Hello, I'm writing an Expression Parser to make my API more refactor friendly and less error prone. basicaly, I want the user to write code like that: repository.Get(entity => entity.Id == 10); instead of: repository.Get<Entity>("Id", 10); Extracting the member name from the left side of the binary expression was straight forward. The problems began when I tried to extract the value from the right side of the expression. The above snippet demonstrates the simplest possible case which involves a constant value but it can be much more complex involving closures and what not. After playing with that for some time I gave up on trying to cover all the possible cases myself and decided to use the framework to do all the heavy lifting for me by compiling and executing the right side of the expression. the relevant part of the code looks like that: public static KeyValuePair<string, object> Parse<T>(Expression<Func<T, bool>> expression) { var binaryExpression = (BinaryExpression)expression.Body; string memberName = ParseMemberName(binaryExpression.Left); object value = ParseValue(binaryExpression.Right); return new KeyValuePair<string, object>(memberName, value); } private static object ParseValue(Expression expression) { Expression conversionExpression = Expression.Convert(expression, typeof(object)); var lambdaExpression = Expression.Lambda<Func<object>>(conversionExpression); Func<object> accessor = lambdaExpression.Compile(); return accessor(); } Now, I get an InvalidOperationException (Lambda parameter not in scope) in the Compile line. when I googled for the solution I came up with similar questions that involved building an expression by hand and not supplying all the pieces, or trying to rely on parameters having the same name and not the same reference. I don't think that this is the case here because I'm reusing the given expression. I would appreciate if someone will give me some pointers on this. Thank you.

  • SQL Injection Protection for dynamic queries

    - by jbugeja
    The typical controls against SQL injection flaws are to use bind variables (cfqueryparam tag), validation of string data and to turn to stored procedures for the actual SQL layer. This is all fine and I agree, however what if the site is a legacy one and it features a lot of dynamic queries. Then, rewriting all the queries is a herculean task and it requires an extensive period of regression and performance testing. I was thinking of using a dynamic SQL filter and calling it prior to calling cfquery for the actual execution. I found one filter in CFLib.org (http://www.cflib.org/udf/sqlSafe): <cfscript> /** * Cleans string of potential sql injection. * * @param string String to modify. (Required) * @return Returns a string. * @author Bryan Murphy ([email protected]) * @version 1, May 26, 2005 */ function metaguardSQLSafe(string) { var sqlList = "-- ,'"; var replacementList = "#chr(38)##chr(35)##chr(52)##chr(53)##chr(59)##chr(38)##chr(35)##chr(52)##chr(53)##chr(59)# , #chr(38)##chr(35)##chr(51)##chr(57)##chr(59)#"; return trim(replaceList( string , sqlList , replacementList )); } </cfscript> This seems to be quite a simple filter and I would like to know if there are ways to improve it or to come up with a better solution?

  • beginning oop php question: do constructors take the place of getter?

    - by Joel
    I'm working through this tutorial: http://www.killerphp.com/tutorials/object-oriented-php/php-objects-page-3.php At first he has you create a setter and getter method in the class: <?php class person{ var $name; function set_name($new_name){ $this->name=$new_name; } function get_name(){ return $this->name; } } php?> And then you create the object and echo the results: <?php $stefan = new person(); $jimmy = new person(); $stefan ->set_name("Stefan Mischook"); $jimmy ->set_name("Nick Waddles"); echo "The first Object name is: ".$stefan->get_name(); echo "The second Object name is: ".$jimmy->get_name(); ?> Works as expected, and I understand. Then he introduces constructors: class person{ var $name; function __construct($persons_name) { $this->name = $persons_name; } function set_name($new_name){ $this->name=$new_name; } function get_name(){ return $this->name; } } And returns like so: <?php $joel = new person("Joel"); echo "The third Object name is: ".$joel->get_name(); ?> This is all fine and makes sense. Then I tried to combine the two and got an error, so I'm curious-is a constructor always taking the place of a "get" function? If you have a constructor, do you always need to include an argument when creating an object? Gives errors: <?php $stefan = new person(); $jimmy = new person(); $joel = new person("Joel Laviolette"); $stefan ->set_name("Stefan Mischook"); $jimmy ->set_name("Nick Waddles"); echo "The first Object name is: ".$stefan->get_name(); echo "The second Object name is: ".$jimmy->get_name(); echo "The third Object name is: ".$joel->get_name(); ?>
