  • How do I protect my website from javascript injection attacks when using rich text editors?

    - by VJ
    Hi all I am using the markitup editor to get the value for one of my fields and storing it a sql server 2008 db. Now I guess the problem is people having script tags and javascript in the editor and injecting malicious scripts and I have my validate input turned false. So can anyone suggest me a way to write a custom validation method that maybe checks for script tags and removes them...or just guide me through the steps i need to do ?...also are there other things also that I should be worried about..?

  • Looping through all attributes of a XML element in XSLT

    - by TheGNUGuy
    Hey everyone, I am trying to use <xsl:for-each select="@*"> to grab all the attributes of a given element but when i do that my <xsl:choose> statement doesn't execute. Here is the element that I'm working with: <textBox id="Airfare" value="" label="text 1"/> Here is the XSLT template I'm using: <xsl:template match="textBox"> <div> <xsl:choose> <xsl:when test="@label"> <xsl:value-of select="@label"/> </xsl:when> <xsl:otherwise> <xsl:text>No Label Defined</xsl:text> </xsl:otherwise> </xsl:choose> <xsl:element name="input"> <xsl:attribute name="type">text</xsl:attribute> <xsl:for-each select="@*"> <xsl:choose> <xsl:when test="@id"> <xsl:attribute name="name">form_<xsl:value-of select="@id"/></xsl:attribute> <xsl:attribute name="id">form_<xsl:value-of select="@id"/></xsl:attribute> </xsl:when> <xsl:when test="@label"> </xsl:when> <xsl:otherwise> <xsl:copy-of select="current()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each> </xsl:element> </div> And when I generate the HTML using PHP I get this: <div>text 1<input type="text" id="Airfare" value="" label="text 1"></div> As you can see it didn't add form_ to the id attribute it didn't generate a name attribute and it didn't skip over the label attribute. Thanks for your help!

  • How to disable html button using JavaScript?

    - by Jack Roscoe
    Hi, I've read that you can disable (make physically unclickable) a html button simply but appending 'disable' to its tag, but not as an attribute, as follows: <input type="button" name=myButton value="disable" disabled> Since this setting is not an attribute, how can I add this in dynamically via JavaScript to disable a button that was previously enabled?

  • Delphi exe, will it run with just BDE configuration?

    - by Roddy
    Hi, I've taken over a legacy application and I have the exe created. If I can configure the BDE then in theory it should be possible to run this. Someone indicated that Delphi needs to be installed in order for the app to run. I'm unsure of that - it doesn't quite make sense to me as there is an exe file. Any input from Delphi experts would be appreciated. Roddy

  • How to select all parent objects into DataContext using single LINQ query ?

    - by too
    I am looking for an answer to a specific problem of fetching whole LINQ object hierarchy using single SELECT. At first I was trying to fill as much LINQ objects as possible using LoadOptions, but AFAIK this method allows only single table to be linked in one query using LoadWith. So I have invented a solution to forcibly set all parent objects of entity which of list is to be fetched, although there is a problem of multiple SELECTS going to database - a single query results in two SELECTS with the same parameters in the same LINQ context. For this question I have simplified this query to popular invoice example: public static class Extensions { public static IEnumerable<T> ForEach<T>(this IEnumerable<T> collection, Action<T> func) { foreach(var c in collection) { func(c); } return collection; } } public IEnumerable<Entry> GetResults(AppDataContext context, int CustomerId) { return ( from entry in context.Entries join invoice in context.Invoices on entry.EntryInvoiceId equals invoice.InvoiceId join period in context.Periods on invoice.InvoicePeriodId equals period.PeriodId // LEFT OUTER JOIN, store is not mandatory join store in context.Stores on entry.EntryStoreId equals store.StoreId into condStore from store in condStore.DefaultIfEmpty() where (invoice.InvoiceCustomerId = CustomerId) orderby entry.EntryPrice descending select new { Entry = entry, Invoice = invoice, Period = period, Store = store } ).ForEach(x => { x.Entry.Invoice = Invoice; x.Invoice.Period = Period; x.Entry.Store = Store; } ).Select(x => x.Entry); } When calling this function and traversing through result set, for example: var entries = GetResults(this.Context); int withoutStore = 0; foreach(var k in entries) { if(k.EntryStoreId == null) withoutStore++; } the resulting query to database looks like (single result is fetched): SELECT [t0].[EntryId], [t0].[EntryInvoiceId], [t0].[EntryStoreId], [t0].[EntryProductId], [t0].[EntryQuantity], [t0].[EntryPrice], [t1].[InvoiceId], [t1].[InvoiceCustomerId], [t1].[InvoiceDate], [t1].[InvoicePeriodId], [t2].[PeriodId], [t2].[PeriodName], [t2].[PeriodDateFrom], [t4].[StoreId], [t4].[StoreName] FROM [Entry] AS [t0] INNER JOIN [Invoice] AS [t1] ON [t0].[EntryInvoiceId] = [t1].[InvoiceId] INNER JOIN [Period] AS [t2] ON [t2].[PeriodId] = [t1].[InvoicePeriodId] LEFT OUTER JOIN ( SELECT 1 AS [test], [t3].[StoreId], [t3].[StoreName] FROM [Store] AS [t3] ) AS [t4] ON [t4].[StoreId] = ([t0].[EntryStoreId]) WHERE (([t1].[InvoiceCustomerId]) = @p0) ORDER BY [t0].[InvoicePrice] DESC -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [186] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1 SELECT [t0].[EntryId], [t0].[EntryInvoiceId], [t0].[EntryStoreId], [t0].[EntryProductId], [t0].[EntryQuantity], [t0].[EntryPrice], [t1].[InvoiceId], [t1].[InvoiceCustomerId], [t1].[InvoiceDate], [t1].[InvoicePeriodId], [t2].[PeriodId], [t2].[PeriodName], [t2].[PeriodDateFrom], [t4].[StoreId], [t4].[StoreName] FROM [Entry] AS [t0] INNER JOIN [Invoice] AS [t1] ON [t0].[EntryInvoiceId] = [t1].[InvoiceId] INNER JOIN [Period] AS [t2] ON [t2].[PeriodId] = [t1].[InvoicePeriodId] LEFT OUTER JOIN ( SELECT 1 AS [test], [t3].[StoreId], [t3].[StoreName] FROM [Store] AS [t3] ) AS [t4] ON [t4].[StoreId] = ([t0].[EntryStoreId]) WHERE (([t1].[InvoiceCustomerId]) = @p0) ORDER BY [t0].[InvoicePrice] DESC -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [186] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1 The question is why there are two queries and how can I fetch LINQ objects without such hacks?

  • Efective way to avoid integer overflow when multiplying?

    - by Jonathan
    Hi, I'm working on a hash function which gets a string as input. Right now I'm doing a loop and inside the hash (an int variable) is being multiplied by a value and then the ASCII code for the current character is added to the mix. hash = hash * seed + string[i] But sometimes, if the string is big enough there is an integer overflow there, what can I do to avoid it while maintaining the same hash structure? Maybe a bit operation included inside the loop?

  • Linq Aggregate function

    - by Nyla Pareska
    I have a List like "test", "bla", "something", "else" But when I use the Aggrate on it and in the mean time call a function it seems to me that after 2 'iterations' the result of the first gets passed in? I am using it like : myList.Aggregate((current, next) => someMethod(current) + ", "+ someMethod(next)); and while I put a breakpoint in the someMethod function where some transformation on the information in the myList occurs, I notice that after the 3rd call I get a result from a former transformation as input paramter.

  • Dynamic Multiple Choice (Like a Wizard) - How would you design it? (e.g. Schema, AI model, etc.)

    - by henry74
    This question can probably be broken up into multiple questions, but here goes... In essence, I'd like to allow users to type in what they would like to do and provide a wizard-like interface to ask for information which is missing to complete a requested query. For example, let's say a user types: "What is the weather like in Springfield?" We recognize the user is interested in weather, but it could be Springfield, Il or Springfield in another state. A follow-up question would be: What Springfield did you want weather for? 1 - Springfield, Il 2 - Springfield, Wi You can probably think of a million examples where a request is missing key data or its ambiguous. Make the assumption the gist of what the user wants can be understood, but there are missing pieces of data required to complete the request. Perhaps you can take it as far back as asking what the user wants to do and "leading" them to a query. This is not AI in the sense of taking any input and truly understanding it. I'm not referring to having some way to hold a conversation with a user. It's about inferring what a user wants, checking to see if there is an applicable service to be provided, identifying the inputs needed and overlaying that on top of what's missing from the request, then asking the user for the remaining information. That's it! :-) How would you want to store the information about services? How would you go about determining what was missing from the input data? My thoughts: Use regex expressions to identify clear pieces of information. These will be matched to the parameters of a service. Figure out which parameters do not have matching data and look up the associated question for those parameters. Ask those questions and capture answers. Re-run the service passing in the newly captured data. These would be more free-form questions. For multiple choice, identify the ambiguity and search for potential matches ranked in order of likelihood (add in user history/preferences to help decide). Provide the top 3 as choices. Thoughts appreciated. Cheers, Henry

  • Web application starter kit

    - by Steve Robillard
    I am looking for a site that allows you to input a project name, choose a doctype, a js library etc. and then generates the directory structure and files to start a web project. I know about project deploy, but it is no longer maintained. There was a new one that was created within the last 2 or 3 months, but for the life of me I can't find it either through Google nor my delicious bookmarks. Any help would be greatly appreciated. Thanks, Steve

  • Focus on textbox based on URL.

    - by Cameron
    I have two forms on one page and want to have the input boxes focused based on the URL. So for example: domain.com/Default.aspx#login and domain.com/Default.aspx#register and the javascript I have this: window.document.getElementById('<%=txtUserName.ClientID %>').focus(); window.document.getElementById('<%=txtEmail.ClientID %>').focus(); it might be better if the urls are Default.aspx?action=login actually (not sure if this effects the way in which it would work)

  • Error handling in the RequestHandler without embedding in URI

    - by hyn
    When a user sends a filled form, I want to print an error message in case there is an input error. One of the GAE sample codes does this by embedding the error message in the URI. Inside the form handler (get): self.redirect('/compose?error_message=%s' % message) and in the handler (get) of redirected URI, gets the message from request: values = { 'error_message': self.request.get('error_message'), ... Is there a way to accomplish the same without embedding the message in the URI?
