  • design time usercontrols - I can't see anything!

    - by taglius
    newbie question, please forgive... I'm developing a Wpf UserControl that will eventually be bound to a business object. The usercontrol is little more than a series of laid out TextBlocks, and perhaps (later) an image or two. As I'm laying out the usercontrol, I can put dummy text into all the TextBlocks so I can see what the usercontrol will look like, but as soon as I change the text property to contain the Binding information: <TextBlock Margin="0,12.8,42,0" Name="lblLastName" FontSize="8" Height="19" VerticalAlignment="Top" Text="{Binding Mode=OneWay, Path=LastName}"/> Then I can no longer see the textbox, or any "placeholder" text. This makes it very difficult to adjust the location and sizes of all the controls on the UserControl. In WinFormas programming, you could set binding information independently of the Text property, so you could at least see the Placeholder text during design time development. It's going to be pretty hard to visually arrange a bunch of invisible TextBlocks! What's the standard solution for this?

  • How to create a VS2010 extension that uses Language Services

    - by Hades32
    Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?

  • Creating a Rails query from a hash of user input

    - by Jamie
    I'm attempting to create a fairly complex search engine for a project using a variable number of search criteria. The user input is sorted into an array of hashes. The hashes contain the following information: { :column => "", :value => "", :operator => "", # Such as: =, !=, <, >, etc. :and_or => "", # Two possible values: "and" and "or" } How can I loop through this array and use the information in these hashes to make an ActiveRecord WHERE query?

  • ASP.NET 2.0 files work in one folder, but NOT in another

    - by Steve
    I am about to leap of a building. I have created an app for a client and all the files are in a folder on their D drive. Now it is time to go production, so I copied all my files and folders to their excisting classic asp folder on the same drive. BUT NOTHING WORKS. The only difference I can see is that DEV does not require HTTPS like the production site. I also made sure all the permissions are the same on both folder. I made sure that the GAC has read rights using the aspnet_regiis tool. I am at the end of my debug knowlegde, could someone please help me out. Here are the error messages I get from the application event log.

  • Create a Font using strings pulled from a string table.

    - by Matthew Smith
    I am writing a tool to create an otf or ttc with only characters defined in our localized string table, so we can cut down memory usage. I already have the information for the Japanese characters we are using but I am unable to find an example of creating a new font based around these characters. Does anyone know of a good example or even the interface I can access to do this? I am working in C# with .NET 3.5. I am looking into Volt and TTOasm from Microsoft, but I am not sure if they will do exactly what I need. Any information is appreciated. Thanks, Matt Smith

  • How do I get HTML Markup for createRange() in Firefox

    - by OneNerd
    I am currently using code similar to this: try { // IE ONLY var theElement = "myElementName"; window.frames[theElement].focus(); var selection = window.frames[theElement].document.selection.createRange(); alert ( selection.htmlText ); } catch(e) { var selection = window.frames[theElement].document.getSelection(); alert ( selection ); } As you can see, I am accessing a node from an iframe (no fun already). I am definitely in new territory here, so am sure there are more issues to arise, but right now, I am trying to get Firefox to give me the same result as IE. In IE, I can access the HTML code of the selection by using the (apparently IE-only) htmlText property of the object returned by createRange(). What I am looking for is the Firefox equivalent to that (or a function that I can use to give me the same result). Anyone know how to do this?

  • Custom drop down

    - by Rob
    I'm trying to create a custom drop down and using the code below it works pretty well - only one problem is if i have more than one drop down, all the links will only activate the first drop down. Any ideas on how I would fix that? (and yes I know about Suckerfish I just need to get this to work) function toggle() { var ele = document.getElementById("dropdown-items"); var text = document.getElementById("dropdown-menu"); if(ele.style.display == "block") { ele.style.display = "none"; } else { ele.style.display = "block"; } }

  • Best way to encrypt certain fiels in SQL Server 2008?

    - by Josh
    I'm writing a .net web app that will read and write information to a SQL 2008 backend database. Some of this information will be highly confidential in nature so I want to encrypt certain data elements. I dont want to use TDE or any full-database encryption for performance reasons. My main concern is protecting this sensitive data as a last resort against a SQL injection or even a database server compromise. My question is what is the best way to do this to preserve performance? Is it faster to use the SQL2008 encryption functions such as EncryptByKey, or would it be faster to encrypt and decrypt the data in the .NET web app itself using a symmetric key stored in the secure web.config and store the encrypted values in the DB?

  • How to fetch message body and attachments in XML format using php/linux from Lotus Domino server?

    - by too
    Has anybody some information about accessing Lotus Domino server to fetch entire mail contents by http(s) requests from php linux server? The article by Andrei Kouvchinnikov describes well how to fetch message list in notes mail folders; after obtaining session id during login one can for example select top 100 messages by calling: https://your.server.domain/mail_db/mailbox.nsf/($Inbox)?ReadViewEntries&Start=1&Count=100 And this works perfectly. The problem arises when I am trying to get message contents (0A1DA5EEB7B65277C12576F50055D811 is an example message unique Id): https://your.server.domain/mail_db/mailbox.nsf/($Inbox)/0A1DA5EEB7B65277C12576F50055D811/?OpenDocument Such request in IE shows frameset with data hard to parse, in less common browsers like Opera it informs about unsupported browser. Ideally if it is possible to fetch notes message contents and all attachments by requesting it in the url, has anybody some information what request would it be? Link to Lotus web calls reference would be even more beneficial.

  • Can I fill in an encypted PDF with iTextSharp?

    - by Cmpalmer
    I have a fillable, saveable PDF file that has an owner password (that I don't have access to). I can fill it out in Adobe reader, export the FDF file, modify the FDF file, and then import it. Then I tried to do it with iText(Sharp). I can't create a PdfStamper from my PdfReader because I didn't provide the owner password to the reader. Is there any way to do this programmatically or must I recreate the document? Even using FdfReader requires a PdfStamper. Am I missing anything? Anything legal that is - I'm pretty sure I could hack the document, but I can't. Ironically, recreating it would probably be ok.

  • How to stream XML data using XOM?

    - by Jonik
    Say I want to output a huge set of search results, as XML, into a PrintWriter or an OutputStream, using XOM. The resulting XML would look like this: <?xml version="1.0" encoding="UTF-8"?> <resultset> <result> [child elements and data] </result> ... ... [1000s of result elements more] </resultset> Because the resulting XML document could be big (tens or hundreds of megabytes, perhaps), I want to output it in a streaming fashion (instead of creating the whole Document in memory and then writing that). The granularity of outputting one <result> at a time is fine, so I want to generate one <result> after another, and write it into the stream. Assume there's already a method that helps with iterating the results and generating Element objects: public nu.xom.Element getNextResult(); So I'd simply like to do something like this pseudocode (automatic flushing enabled, so don't worry about that) : open stream/writer write declaration write start tag for <resultset> while more results: write next <result> element write end tag for <resultset> close stream/writer I've been looking at Serializer, but the necessary methods, writeStartTag(Element), writeEndTag(Element), write(DocType) are protected, not public! Is there no other way than to subclass Serializer to be able to use those methods, or to manually write the start and end tags directly into the stream as Strings, bypassing XOM altogether? (The latter wouldn't be too bad in this simple example, but in the general case it would get quite ugly.) Am I missing something or is XOM just not made for this? With dom4j I could do this easily using XMLWriter - it has constructors that take a Writer or OutputStream, and methods writeOpen(Element), writeClose(Element), writeDocType(DocumentType) etc. Compare to XOM's Serializer where the only public write method is the one that takes a whole Document. Please refrain from answering if you're not familiar with XOM! I specifically want to know if and how you can do this kind of streaming with that library. (This is related to my question about the best dom4j replacement where XOM is a strong contender.)

  • How could I get informations about the SIM card on Windows CE

    - by jeleb
    Hello, I am using a device running on WindowsCE 5.00. I cannot connect the GPRS, there is an error message telling that the port cannot be opened and may be in use by another application. I am not sure but I think the port it is talking about is a comp port to the SIM card that cannot be opened because the SIM doesn't work anymore. To tell the truth, it is likely that one of my coworker did lock the SIM and kept his mouth shut ... How could I get any information about the SIM on Windows CE ? I am new at this and Windows CE is not really user friendly ... I have been strongly searching this on internet but didn't find anything. Any kind of information will be welcomed. Thanks,

  • CodeIgniter based e-shop, shipping and gift address design problem

    - by alexander
    While building an ecommerce platform I have run into design problems. I'm working with the built-in CodeIgniter's cart class. It stores all the cart information in session. Let say that cart has already been filled with products and user clicks checkout. When should I store order in database? Just after that click or after several steps of gathering information and stoing it in session? How to deal with additional features like different shipping methods? Should I add it to the basket first and get additional (gift address) to session? I dont want to store it in database because of the relation between gift address and order is needed and since I dont know what's the ID of the order. I'm puzzled :) Additionally I think its crucial to keep cart aware of shipping methods and additional bought services (by selecting gift address there is an extra fee) because the cart content is just like an reciept? In brief, what is the best practice to process checkout?

  • Is it really wrong to version documents using CouchDB's default behaviour?

    - by Tomas Sedovic
    This is one of those "I know I shouldn't do this but it's oh so convenient." questions. Sorry about that. I plan to use CouchDB for storing a bunch of documents and keeping their entire revision history. CouchDB does the versioning automatically, but it is strongly discouraged for programmer's use: "You cannot rely on document revisions for any other purpose than concurrency control." From what I've found on the CouchDB wiki, the versions can get deleted either during compaction or during replication. As far as I can tell, Compaction must always be triggered manually and Replication occurs only when there's more than one database server. The question is: if I won't run compaction and will use only single database instance for my documents, can I just use CouchDB's document versioning and expect it to work? What other problems I might run into? E.g. does not running compaction hurt the performance or consume significantly more disk space (than if I did handle the versioning manually)?

  • reference symbols on the main timeline

    - by vasion
    this is one of those upsurdly basic questions for which google does not work. I have usually dispatched events from my classes and dealt with the user interface in the document class. But now i want to separate all the UI in a separate class, accessible by other classes. I have added it as a child to the main/document class, but how do i reference the main class without going through parent.parent shananigans? edit. one more thing i remembered. Some of my UI elements are not programatically added.

  • Multiple Cookie Generation Issue

    - by Shannon
    Hi all, jQuery newbie here. I need to be able to set multiple cookies within the code without have to change out this variable each and every time. Is there any way to make this code generate unique cookies for different pages? As it is now, I'm having to rename that variable for each page that the jQuery animations exist on. (sbbcookiename) Background on the issue: We are having issues with the sliders not autoplaying once one has already been triggered, due to it the cookie having been cached. Thanks for your help. (function(){ jQuery.noConflict(); var _TIMEOUT= 1000, initTimer= 0, sbLoaded= false, _re= null ; initTimer= setTimeout(initSlider, _TIMEOUT); jQuery(document).ready(initSlider); function initSlider(){ if(sbLoaded) return; if (jQuery('#campaign_name').length > 0) { var sbbcookiename = jQuery('#campaign_name').attr('class'); } else { var sbbcookiename = "slider728x90"; } var slideTimeout //timer ,sbTrigger = jQuery('#slidebartrigger') //convenience ,sbFirstSlide = (document.cookie.indexOf(sbbcookiename) == -1) //check cookie for 'already seen today' ; clearTimeout(initTimer); sbLoaded= true; function toggleSlideboxes(){ if(slideTimeout) clearTimeout(slideTimeout); var isDown = sbTrigger.is('.closeSlide'); jQuery('#slidebar')['slide' + (isDown ? 'Up' : 'Down')]((isDown ? 1000 : 1000), function(){ if(sbFirstSlide){ //if 'first time today' then clear for click-to-replay sbTrigger.removeClass('firstSlide'); sbFirstSlide = false; } sbTrigger[(isDown ? 'remove' : 'add') + 'Class']('closeSlide').one('click', toggleSlideboxes); if(!isDown) slideTimeout = setTimeout(toggleSlideboxes, 4000); }); } if(sbFirstSlide){ //not seen yet today so set a cookie for expire tomorrow, then toggle the slide boxes... var oneDay = new Date(); oneDay.setUTCDate(oneDay.getUTCDate()+1); oneDay.setUTCHours(0, 0, 0, 0); //set to literally day-by-day, rather than 24 hours document.cookie=sbbcookiename+"=true;path=/;expires="+oneDay.toUTCString(); toggleSlideboxes(); }else{ //already seen today so show the trigger and set a click event on it... sbTrigger.removeClass('firstSlide').one('click', toggleSlideboxes); } } })();

  • How to deal with presence or not of xml namespaces using xslt.

    - by Mycol
    I have some XML/TEI documents, and i'm writing an XSLT 2.0 to extract their content. Almost all TEI documents has no namespace, but one has the default namespace (xmlns="http://www.tei-c.org/ns/1.0"). So all documents has the same aspect, with unqulified tags like <TEI> or <teiHeader>, but if I try to extract the content, all works with "non-namespaced-documents", but nothing (of course) is extracted from the namespaced-document. So i used the attribute xpath-default-namespace="http://www.tei-c.org/ns/1.0" and now (of course) the only document working is the namespaced one. I can't edit documents at all, so what I'm asking is if there's a way to change dynamically the xpath-default-namespace in order to make work xpaths like //teiHeader both with namespaced and non-namespaced documents

  • C# Crypto API examples

    - by Gearoid Murphy
    Hello, I'm looking for examples + information on how to extract certificate information from the windows certificate store and perform operations like verifying signatures using the retrieved certificates. The API documentation for C# in this regard is quite poor, with many of the entries in msdn marked with "This language is not supported, or no code example is available.", I'm sorry I can't be more specific, I haven't done any programming using cryptographic api's. The particular certificate will be provided via a USB token. Any help or pointers would be much appreciated, thanks.

  • How can I temporarily redirect printf output to a c-string?

    - by Ben S
    I'm writing an assignment which involves adding some functionality to PostgreSQL on a Solaris box. As part of the assignment, we need to print some information on the client side (i.e.: using elog.) PostgreSQL already has lots of helper methods which print out the required information, however, the helper methods are packed with hundreds of printf calls, and the elog method only works with c-style strings. Is there I way that I could temporarily redirect printf calls to a buffer so I could easily send it over elog to the client? If that's not possible, what would be the simplest way to modify the helper methods to end up with a buffer as output?

  • How to read pixel values of a video?

    - by vikramtheone
    Hi Guys, I recently wrote C programs for image processing of BMP images, I had to read the pixel values and process them, it was very simple I followed the BMP header contents and I could get most of the information of the BMP image. Now the challenge is to process videos (Frame by Frame), how can I do it? How will I be able to read the headers of continuous streams of image frames in a video clip? Or else, is it like, for example, the mpeg format will also have universal header, upon reading which I can get the information about the entire video and after the header, all the data are only pixels. I hope I could convey. Has anyone got experience with processing videos? Any books or links to tutorials will be very helpful. Vikram

  • Is there an "extended" UIHint attribute to apply CSS styles for DisplayFor - EditorFor templates?

    - by AJ
    Intro: After reading Brad Wilson Metadata series and searching unsuccesfully on google, I was wondering: Question: Has any OS project / code been created that allows you to tag CSS styles in the Meta information, for example in my (buddy) Model, I want to be able to decorate a property with multiple CSS styles (a single style you can fake with UIHint, I want to set many possible styles - and be able to "cross-utilise") eg. public class MyModel { [DisplayCssHint("h5")] [DisplayCssHint("color:#777;")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Title{ get;set; } [DisplayCssHint(".normaltext")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Message {get;set;} } Thoughts: I know that this does not seem like a logical place to put styling information, however as it is metadata and is discriptive... besides it would be nice to do this while prototyping - (especially being able to apply class styles and extending it further - to generate .Less files would really be cool! more to the point I would hate to write it, if its already been done ;). Any links/pointers/idea's would be appreciated. Thanks,

  • selectors-api for data attributes

    - by MJ
    In HTML5, CSS selectors seem to operate well with data-* attributes. For example: <style> div[data-foo='bar'] { background:#eee; } </style> <div data-foo='bar'>colored</div> <div>not colored</div> will properly style the first . But, attempts to select such elements using the selectors-api fail. Examples: var foos = document.querySelectorAll("div[data-foo]='bar'"); or var foos = document.querySelectorAll("div data-foo='bar'"); in Chrome and Safari, this produces a cryptic error: SYNTAX_ERR: DOM Exception 12 Any thoughts on how to use the selectors-api to properly select elements on the basis of data-* attributes?
