  • Delegates in .NET: how are they constructed ?

    - by Saulius
    While inspecting delegates in C# and .NET in general, I noticed some interesting facts: Creating a delegate in C# creates a class derived from MulticastDelegate with a constructor: .method public hidebysig specialname rtspecialname instance void .ctor(object 'object', native int 'method') runtime managed { } Meaning that it expects the instance and a pointer to the method. Yet the syntax of constructing a delegate in C# suggests that it has a constructor new MyDelegate(int () target) where I can recognise int () as a function instance (int *target() would be a function pointer in C++). So obviously the C# compiler picks out the correct method from the method group defined by the function name and constructs the delegate. So the first question would be, where does the C# compiler (or Visual Studio, to be precise) pick this constructor signature from ? I did not notice any special attributes or something that would make a distinction. Is this some sort of compiler/visualstudio magic ? If not, is the T (args) target construction valid in C# ? I did not manage to get anything with it to compile, e.g.: int () target = MyMethod; is invalid, so is doing anything with MyMetod, e.g. calling .ToString() on it (well this does make some sense, since that is technically a method group, but I imagine it should be possible to explicitly pick out a method by casting, e.g. (int())MyFunction. So is all of this purely compiler magic ? Looking at the construction through reflector reveals yet another syntax: Func CS$1$0000 = new Func(null, (IntPtr) Foo); This is consistent with the disassembled constructor signature, yet this does not compile! One final interesting note is that the classes Delegate and MulticastDelegate have yet another sets of constructors: .method family hidebysig specialname rtspecialname instance void .ctor(class System.Type target, string 'method') cil managed Where does the transition from an instance and method pointer to a type and a string method name occur ? Can this be explained by the runtime managed keywords in the custom delegate constructor signature, i.e. does the runtime do it's job here ?

  • How to Convert using of SqlLit to Simple SQL command in C#

    - by Nasser Hajloo
    I want to get start with DayPilot control I do not use SQLLite and this control documented based on SQLLite. I want to use SQL instead of SQL Lite so if you can, please do this for me. main site with samples http://www.daypilot.org/calendar-tutorial.html The database contains a single table with the following structure CREATE TABLE event ( id VARCHAR(50), name VARCHAR(50), eventstart DATETIME, eventend DATETIME); Loading Events private DataTable dbGetEvents(DateTime start, int days) { SQLiteDataAdapter da = new SQLiteDataAdapter("SELECT [id], [name], [eventstart], [eventend] FROM [event] WHERE NOT (([eventend] <= @start) OR ([eventstart] >= @end))", ConfigurationManager.ConnectionStrings["db"].ConnectionString); da.SelectCommand.Parameters.AddWithValue("start", start); da.SelectCommand.Parameters.AddWithValue("end", start.AddDays(days)); DataTable dt = new DataTable(); da.Fill(dt); return dt; } Update private void dbUpdateEvent(string id, DateTime start, DateTime end) { using (SQLiteConnection con = new SQLiteConnection(ConfigurationManager.ConnectionStrings["db"].ConnectionString)) { con.Open(); SQLiteCommand cmd = new SQLiteCommand("UPDATE [event] SET [eventstart] = @start, [eventend] = @end WHERE [id] = @id", con); cmd.Parameters.AddWithValue("id", id); cmd.Parameters.AddWithValue("start", start); cmd.Parameters.AddWithValue("end", end); cmd.ExecuteNonQuery(); } }

  • Is there more to HTML forms than http://www.w3schools.com/html/html_forms.asp ?

    - by mawg
    I am creating a form designer. It will generate PHP code which will produce an HTML form. Users will fill in fields and the PHP will store user input in a MySql database (and, of course, they can use the designer to generate forms which query the database). I am using Borland C++ Builder (very similar to Delphi & and you can get the same idea from VB, MSVC, Qt ... any IDE with a RAD GUI designer). Looking at the W3C page http://www.w3schools.com/html/html_forms.asp it seems that the components I can use for my form and retrieve data from are - edit box / TEdit / <input type="text" - memo / TMemo / <input type="textarea" - check box / TCheckBox / <input type="CheckBox" - Combo box / TComboBox / <select ... <option... - Radio group / TRadioGroup / <input type="radio" - Group box / TGroupBox / <fieldset ... <legend ... - Panel / TPanel / <fieldset ... I am unsure whether to allow button / TButton/ input type="button" - other than a single submit button which my form designer program automatically adds to the end of the generated form. But my real question is - did I miss any? It might be nice to have masked edit which only accepts numbers, or maybe some form of "spin control" (TUpDown, or slider + linked read only TEdit), so that the user can click & hold to increment/decrement an integer value. And a calendar component would be nice. Very important: I want to implement it all server-side in PHP, so no client-side JS or Ajax or the likes. If there anything else that I can add to make my generated forms look more impressive in the browser?

  • Right-Align and Vertical Align label with checkbox/radio button CSS

    - by Jon
    Hi Everyone, I'm very close and have this working in Safari, Firefox and IE8, however IE7 the labels and radio buttons do not align vertically. My HTML is: <div id="master-container"> <fieldset id="test"> <legend>This is a test of my CSS</legend> <ul class="inputlist"> <li> <label for="test1">Test 1</label> <input name="test1" id="test1" type="checkbox" disabled="disabled"/> </li> <li> <label for="test2">Test 2</label> <input name="test2" id="test2" type="checkbox" disabled="disabled"/> </li> </ul> </fieldset> </div> My CSS Is: html{font-family:Arial,Helvetica,sans-serif;} #master-container{width:615px;font-size:12px;} ul.inputlist{list-style-type:none;} ul.inputlist li{width:100%;margin-bottom:5px;} ul.inputlist li label{width:30px; text-align:right; margin-right:7px;float:left;} Any suggestions? Thanks! EDIT: Based on the suggestion to check the rest of my html and css. I updated the code above and now it accurately demonstrates the problem. If I take font-size out of #master-container it lines up but then it is not the proper font-size. I tried to add a font-size to ul.inputlist li input but that didn't help. Any suggestions? Thanks for your help everyone!

  • Background-color puzzle on CSS for heading/title div.

    - by ProfK
    I have the following title div setup, but when only the leftmost div has content, the red background for the title is not applied.

  • Matlab crashes on library initialize when called from Java

    - by David Sauter
    Hello everyone. The setup I have is I'm using a Java application to call native C-code with JNI, which in turn starts up the MATLAB runtime and calls functions on it (I know there are other solutions to call MATLAB methods from Java). The problem is that the MATLAB engine crashes at some point during the initialization and I don't know what's causing it exactly. The crash causes my jvm to terminate, I assume it's some kind of memory corruption. The C++ code calling MATLAB functions that is actually crashing is JNIEXPORT void JNICALL some_jni_vodoo_initializeLibrary(JNIEnv* env, jclass thisClass) { try { if (!mclInitializeApplication(NULL, 0)) { THROW_EXCEPTION(env, "Could not initialize the application properly."); return; } if (!<library>Initialize()) { THROW_EXCEPTION(env, "Could not initialize the library."); return; } } ... The function <library>Initialize() crashes here, the Java error log reads Stack Trace: [0] jmi.dll:0x793f4175(0x7934cdca, 1, 0x7937e67c "à;.y`[email protected] in C:\BUILD_ARE..", 0x792d6a32) [1] jvm.dll:0x792df9a5(0xc0000005, 0x79356791, 0x4961b400 "Ð\8y", 0x6d8b29de) [2] jvm.dll:0x792e0431(0x8b515008, 0x70f0e8ce, 0x8b5ffffa, 0xc25d5ec6) ------------------------------------------------------------------------ Fatal Java Exception detected at Fri Apr 30 11:08:08 2010 ------------------------------------------------------------------------ Configuration: MATLAB Version: 7.8.0.347 (R2009a) MATLAB License: unknown Operating System: Microsoft Windows Vista Window System: Version 6.0 (Build 6002: Service Pack 2) Processor ID: x86 Family 6 Model 10 Stepping 5, GenuineIntel Virtual Machine: Java is not enabled Default Encoding: windows-1252 Java is not enabled I really have no idea what could be wrong. Is there not enough memory from the jvm? I guess the problem is somehow related to Java, since calling the JNI functions from a simple test C++ program works fine... Thanks

  • Date since 1600 to NSDate?

    - by Steven Fisher
    I have a date that's stored as a number of days since January 1, 1600 that I need to deal with. This is a legacy date format that I need to read many, many times in my application. Previously, I'd been creating a calendar, empty date components and root date like this: self.gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar ] autorelease]; id rootComponents = [[[NSDateComponents alloc] init] autorelease]; [rootComponents setYear: 1600]; [rootComponents setMonth: 1]; [rootComponents setDay: 1]; self.rootDate = [gregorian dateFromComponents: rootComponents]; self.offset = [[[NSDateComponents alloc] init] autorelease]; Then, to convert the integer later to a date, I use this: [offset setDay: theLegacyDate]; id eventDate = [gregorian dateByAddingComponents: offset toDate: rootDate options: 0]; (I never change any values in offset anywhere else.) The problem is I'm getting a different time for rootDate on iOS vs. Mac OS X. On Mac OS X, I'm getting midnight. On iOS, I'm getting 8:12:28. (So far, it seems to be consistent about this.) When I add my number of days later, the weird time stays. OS | legacyDate | rootDate | eventDate ======== | ========== | ==========================|========================== Mac OS X | 143671 | 1600-01-01 00:00:00 -0800 | 1993-05-11 00:00:00 -0700 iOS | 143671 | 1600-01-01 08:12:28 +0000 | 1993-05-11 07:12:28 +0000 In the previous release of my product, I didn't care about the time; now I do. Why the weird time on iOS, and what should I do about it? (I'm assuming the hour difference is DST.) I've tried setting the hour, minute and second of rootComponents to 0. This has no impact. If I set them to something other than 0, it adds them to 8:12:28. I've been wondering if this has something to do with leap seconds or other cumulative clock changes. Or is this entirely the wrong approach to use on iOS?

  • CSS selector involving pseudo class first-child and dropcap

    - by Grnbeagle
    Hi, I need to format HTML similar to below. Basically a quote is optional, and I need to dropcap the first letter of the body paragraph. <article> <p class="quote"> <!-- quote is optional --> Genius begins great works; labor alone finishes them.-- Joseph Joubert </p> <p> <!-- "L" is a dropcap --> Life is like a box of chocolates. </p> <p>...</p> <p>...</p> </article> My CSS looks like this: article > p:first-child:first-letter { float: left; font-family: Georgia, serif; font-size: 360%; line-height: 0.85em; margin-right: 0.05em; } p.quote { font-weight: bold; } It doesn't work currently when the quote is introduced. AFAIK I can't select the article's first child P which is not class "quote." I'll use jQuery if I can't figure this out, but for now I'm looking for a way to do it CSS only. Thanks in advance!

  • Exporting non-public type through public API

    - by feelgood
    What if I have few factory methods returning non-public type and pairing set of methods which gives variables of this non-public type? This results with titled warning message in NetBeans. In result public API will contain only two pairing sets of methods. The reason is to make my type hierarchy sealed (like seald classes in Scala) and allow users only instantiate these types through factory methods. So we get DSL in some sense. For example, Schedule class represented by calendar fields' contraints. There are some types of contraints - Range, Singleton, List, FullSet - with NumberSet interface as a root. We don't want to expose these types and how Schedule interact with them. We just want the specification from the user. So we make NumberSet package-private. In class Schedule we create few factory-methods for constraints: NumberSet singleton(int value); NumberSet range(int form, int to); NumberSet list(NumberSet ... components); and some methods for creating Schedule object: Schedule everyHour(NumberSet minutes); Schedule everyDay(NumberSet minutes, NumberSet hours); User can only use them in the manner: Schedule s = Schedule.everyDay( singleton(0), list(range(10-15), singleton(8)) ); Is it bad idea?

  • SQLite self-join performance

    - by Derk
    What I essentially want, is to retreive all features and values of products which have a particular feature and value. For example: I want to know all available hard drive sizes of products that have an Intel processor. I have three tables: product_to_value (product_id, feature_id, value_id) features (id, value) // for example Processor family, Storage size, etc. values (id, value) // for example Intel, 60GB, etc The simplified query I have now: SELECT features.name, featurevalues.name, featurevalues.value FROM products, products as prod2, features, features as feat2, values, values as val2 WHERE products.feature = features.id AND products.value = values.id AND products.product = prod2.product AND prod2.feature_id = feat2.id AND prod2.value_id = val2.id AND features.id = ? AND feat2.id = ? All columns have an index. I am using SQLite. The problem is that it's very slow (70ms per query, without the self-join it's <1ms). Is there a smarter way to fetch data like this? Or is this too much to ask from SQLite? I personally think I am simply overlooking something, as I am quite new to SQLite.

  • rails + sheevaplug = rails home development server and more

    - by microspino
    Hello I'd like to build a "Rails Brick" using a Sheevaplug from Marvell (O.S. is Ubuntu out of the box but You can install other distributions on It). It will be a home server and a silent, low cost (99$) low energy development machine. I'd like to add rails RVM, lot of gems, git-based heroku like deployment, passenger + nginx. This way I could have a portable server with a complete development environment and maybe I could find a hosting company where I can co-locate a grid of this devices or I can sell It as a simple little server for 10 or less users offices, with some centralized rails services (I think to a CMS, a BLOG, a WIKI, calendar or whatever this little jewel could afford). The usb port could make It a print server too or a UMTS link to the web via HUAWEI like usb UMTS keys. Can you give me some hint about: Is this project a crazy-close-to-failure idea? Why? which gem would You include? which rails open source app would you suggest? I have already an Excito Bubba Server at home, I saw the TonidoPlug so It came up in my mind to build something similiar but Rails based (Bubba is PHP based, TonidoPlug I don't know but It does not seems a Rails thing).

  • mtl, transformers, monads-fd, monadLib, and the paradox of choice

    - by yairchu
    Hackage has several packages for monad transformers: mtl: Monad transformer library transformers: Concrete functor and monad transformers monads-fd: Monad classes, using functional dependencies monads-tf: Monad classes, using type families monadLib: A collection of monad transformers. mtl-tf: Monad transformer library using type families mmtl: Modular Monad transformer library mtlx: Monad transformer library with type indexes, providing 'free' copies. compose-trans: Composable monad transformers (and maybe I missed some) Which one shall we use? mtl is the one in the Haskell Platform, but I keep hearing on reddit that it's uncool. But what's bad about choice anyway, isn't it just a good thing? Well, I saw how for example the authors of data-accessor had to make all these to cater to just the popular choices: data-accessor-monadLib library: Accessor functions for monadLib's monads data-accessor-monads-fd library: Use Accessor to access state in monads-fd State monad class data-accessor-monads-tf library: Use Accessor to access state in monads-tf State monad type family data-accessor-mtl library: Use Accessor to access state in mtl State monad class data-accessor-transformers library: Use Accessor to access state in transformers State monad I imagine that if this goes on and for example several competing Arrow packages evolve, we might see something like: spoonklink-arrows-transformers, spoonklink-arrows-monadLib, spoonklink-tfArrows-transformers, spoonklink-tfArrows-monadLib, ... And then I worry that if spoonklink gets forked, Hackage will run out of disk space. :) Questions: Why are there so many monad transformer packages? Why is mtl [considered] uncool? What are the key differences? Most of these seemingly competing packages were written by Andy Gill and are maintained by Ross Paterson. Does this mean that these packages are not competing but rather work together in some way? And do Andy and Ross consider any of their own packages as obsolete? Which one should me and you use?

  • Missing chars in JpGraph

    - by Álvaro G. Vicario
    I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?

  • trouble with font-face in meteor based on Discover Meteor microscope app

    - by charliemagee
    I've gone through the Discover Meteor book and successfully created Microscope. Now I'm trying to build my own app based on what I've learned. I want to use @font-face for fonts and icon fonts. I can't get them to show up. Here's my directory structure: client/stylesheets I've got my fonts in the stylesheets folder. I'm using scss, by the way, and that's working fine with the scss package. Here's how I'm calling the fonts in the stylesheet: @font-face { font-family: 'AmaranthItalic'; src: url('Amaranth-Italic-webfont.eot'); src: url('Amaranth-Italic-webfont.eot?#iefix') format('embedded-opentype'), url('Amaranth-Italic-webfont.woff') format('woff'), url('Amaranth-Italic-webfont.ttf') format('truetype'), url('Amaranth-Italic-webfont.svg#AmaranthItalic') format('svg'); font-weight: normal; font-style: normal; } I've tried '/stylesheets/Amaranth etc. and all other combinations that I can think of and nothing is working. I've tried putting them in public. Nothing. I know files like this are supposed to go in public folder but that seems to kill the stylesheets entirely. I'm not sure why the Microscope directory design would cause that to happen. These question/answers didn't help: using font-face in meteor? Icon font from fontello not working with Meteor js Thanks for any help.

  • Making Firefox render canvas text the same as CSS text

    - by Dan Forys
    I've been experimenting with the canvas tag and Javascript. I've made a page that takes Tweets from the Twitter public timeline and animates them into view. It works by using a canvas element in the background for the animation. When the animation is complete, it creates a div element with the same text over the top. I do this so that the tweet text is selectable and links are clickable. Now, in Safari, Chrome and even Opera, the canvas text and div text look almost exactly the same. Yet in Firefox, the size of the text is different enough to make it 'jump' at the point it changes into the div. Does anyone know how to make Firefox render the text the same on the canvas element and the div using CSS? Or is this a rendering inconsistency with the engine. I have put the page on my website if you want to see what I mean. Now for the code: The CSS I'm using for rendering the div contains: line-height: 21px; font-weight: 100; font-family: Georgia, "New Century Schoolbook", "Nimbus Roman No9 L", serif; font-size: 20px; For rendering on the canvas I'm using: this.context.font = this.scale + 'px Georgia'; this.context.fillStyle = "white"; this.context.strokeStyle = 'white'; this.context.fillText(this.text, 0, 0); this.context.strokeText(this.text, 0, 0); where this.scale is an animated scale factor that finishes at 20px exactly. So, to recap, I'm using the same font and ending up at the same px size, yet Firefox renders the text differently between Canvas and CSS. (edit) Here's a screenshot example: First line is the text animating in using canvas, second line is the resulting div.

  • IE6 background-position(?) issue

    - by turezky
    I apply to stackoverflow as my last resort. I got this ie6 bug while using the image at the background of the link. It seems that ie6 scrolls the background. How can I avoid it? At some width it shows like this: And at some other it shows like that: IE7 & FF show this just like I expect: The links are placed inside the div which is floating to the right. <a href="/tr" class="menuLink" style="background-image:url(/img/tr.png);">TR</a> <a href="/eng" class="menuLink" style="background-image:url(/img/eng.png); margin-right:30px;">ENG</a> <a href="/logout" class="menuLink" style="background-image:url(/img/logout.png);"><?=$ui["exit"];?></a> .menuLink { font-family:"Tahoma"; font-size:11px; color:#003300; text-decoration:underline; font-weight: bold; background-position:0% 50%; background-repeat:no-repeat; } .menuLink:hover { font-size:11px; color:#047307; text-decoration:underline; font-weight: bold; } Any hints how can I avoid this?

  • Writing to a new window with javascript... get access denied

    - by Søren
    Hello gurus :) I have been struggling with this for a while now, and decided it was time to ask for help. I am trying to create a print function on an aspx page, and I am using javascript to do this: function PrintContentCell() { var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,"; display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25"; var content_innerhtml = document.getElementById("testTable").innerHTML; var document_print = window.open("Loading.htm", "", display_setting); document_print.document.open(); document_print.document.write('<html><head><title>Print</title></head>'); document_print.document.write('<body style="font-family:verdana; font-size:12px;" onLoad="self.print();self.close();" >'); document_print.document.write(content_innerhtml); document_print.document.write('</body></html>'); document_print.print(); document_print.document.close(); return false; } I get "Access Denied" when the script tries to write to the new window. The Loading.htm file is just a very slim html document writing out the text "Loading...". I had hoped this would work after reading this thread: http://stackoverflow.com/questions/735136/ie-6-7-access-denied-trying-to-access-a-popup-window-document Anybody can help?

  • Beginner question about CSS and layout and height

    - by vtortola
    Hi, I'm trying to create a very simple page that contains a container, a header, a left column and a footer: [containter] [header /] [content /] [leftBar /] [footer /] [/containter] (Sorry, I cannot paste the code properly, only appears the tag "body" and the rest disapears :S ... ) As you can see, very simple stuff. I want to use the 100% of the height, as I can do with the width, but I simply don`t get it work :S At his moment I'm using min-height, but how could I use the height:100% ? What I like is that the footer is always visible, and you scroll the content. This is what I have till the moment: body { font-family: Verdana; font-size: 0.8em; background-color:#f1f1f1; } container { border:solid 2px Black; position:absolute; left:10%; width:80%; margin:auto; } header { height:20px; background: #DDDDDD; } leftBar { width: 20%; background: #669966; min-height:600px; postion:absolute; top:20px; bottom:20px; } content { float:right; background-color: #cdcde6; position:absolute; left:20%; right:0px; bottom:20px; top:20px; padding:5px; } footer { position:absolute; height:20px; } I'm reading a book about CSS, but I still don't get the part about the height :S Thanks in advance.

  • Parsing a blackberry .ipd file

    - by galaxywatcher
    I recently lost my Blackberry. When I discovered it was gone very shortly afterwards and called it, the sim card had already been removed. I ain't seeing that Blackberry again. Ok. I am out $300, but at least my data is backed up. I had an older working Blackberry fortunately and I got a new sim card and proceeded to restore my data using Blackberry Desktop Manager. 7000+ emails, hundreds of autotext entries, sms messages, calendar events, all backing up. Looking good. Lo and behold! My Address Book contacts refuse to back up? I try advanced, and it is greyed out as an option to restore. Far more frustrating than losing my bberry in the first place is wrangling with software that defies human logic. Ok, now I guess I will have to enter all 327 names by hand. That is, if I can read the .ipd file. I have tried the free version of ABC Amber Blackberry editor, but when I open the .ipd file, the contacts just do not show up. I am beginning to feel like the gods are conspiring against me. Then I found this: http://jabide.com/2009/03/parse-blackberry-ipd-files/ He posted a perl script that claims to extract the files. I copied and pasted the code and it did list all the different databases in my .ipd file, I was elated that a cool solution like this was published. I followed the instructions and garbled data with some discernible ascii was sent to standard output unlike a .csv file like he said it would. This is enough to make a grown man cry. Does anyone out there have a solution to extract my address book contacts from an .ipd file?
