  • Read a text file

    - by Cyprus106
    I have looked everywhere and surprisingly can't find a good solution to this! I've got the following code that is supposed to read a text file and display it's contents. But it's not reading, for some reason. Am I doing something wrong? FTR, I can't use PHP for this. It's gotta be Javascript. var txtFile = new XMLHttpRequest(); txtFile.open("GET", "http://www.mysite.com/todaysTrivia.txt", true); txtFile.send(null); txtFile.onreadystatechange = function() { if (txtFile.readyState == 4) { // Makes sure the document is ready to parse. alert(txtFile.responseText+" - "+txtFile.status); //if (txtFile.status === 200) { // Makes sure it's found the file. var doc = document.getElementById("Trivia-Widget"); if (doc) { doc.innerHTML = txtFile.responseText ; } //} } txtFile.send(null); } Any good ideas what I'm doing wrong? It just keeps givimg me a zero status. EDIT: I guess it would be a good idea to explain why I need this code. It's basically a widget that other folks can put on their own websites that grabs a line of text from my website and displays it on theirs. The problem is that it really can't be server-side since I've got zero control over everyone else's sites that use this.

  • Continuous build infrastructure recommendations for primarily C++; GreenHills Integrity

    - by andersoj
    I need your recommendations for continuous build products for a large (1-2MLOC) software development project. Characteristics: ClearCase revision control Approx 80% C++; 15% Java; 5% script or low-level Compiles for Green Hills Integrity OS, but also some windows and JVM chunks Mostly an embedded system; also includes some UI pieces and some development support (simulation tools, config tools, etc...) Each notional "version" of the deliverable includes deployment images for a number of boards, UI machines, etc... (~10 separate images; 5 distinct operating systems) Need to maintain/track many simultaneous versions which, notably, are built for a variety of different board support packages Build cycle time is a major issue on the project, need support for whatever features help address this (mostly need to manage a large farm of build machines, I guess..) Operates in a secure environment (this is a gov't program) (Edited to add: This is a classified program; outsourcing the build infrastructure is a non-starter.) Interested in any best practices or peripheral guidance you might offer. The build automation issues is one of several overlapping best practices that appear to be missing on the program, but try to keep your answers focused on build infrastructure piece and observations directly related. Cost is not an object. Scalability and ease of retrofitting onto an existing infrastructure are key. JA

  • download file, without saving in server

    - by lolalola
    Hi, Or possible for users to download the file without saving it on the server? I am getting data from the database, and I want to save them .doc (MS Word) file. if(isset($_POST['save'])) { $file = "new_file2.doc"; $stringData = "Text text text text...."; //This data put in new Word file $fh = fopen($file, 'w'); fwrite($fh, $stringData); fclose($fh); header('Content-Description: File Transfer'); header('Content-type: application/msword'); header('Content-Disposition: attachment; filename="'.$file.'"'); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); unlink($file); exit; } How should the code look like without this: " $fh = fopen($file, 'w'); fwrite($fh, $stringData); fclose($fh);" and this "unlink($file);" I hope to understand what I need enter code here

  • Google Chrome is doing things wrong again

    - by Stefan Liebenberg
    Chrome is wrongly reporting width and height values for images during, or just after, load time. Jquery is used in this code example: <img id='image01' alt='picture that is 145x134' src='/images/picture.jpg' /> <script> var img = $( 'img#image01' ) img.width() // would return 145 in Firefox and 0 in Chrome. img.height() // would return 134 in Firefox and 0 in Chrome. </script> If you put the script in a onload function, the result is the same. but if you run the code a few seconds after the page has loaded, chrome returns the correct result. <script> function example () { var img = $( 'img#image01' ); img.width() // returns 145 in both Firefox and Chrome. img.height() // returns 134 in both Firefox and Chrome. } window.setTimeout( example, 1000 ) </script> Also if you specify the width and height values in the img tag, the script seems to work as expected in both Firefox and Chrome. <img id='image01' src='/images/picture.jpg' width=145 height=134 /> But as you cannot always control the html input, this is not an ideal workaround. Can jQuery be patched with a better workaround for this problem? or will I need to specify the width and height for every image in my code?

  • Custom ASP.net UserControl List<T> Property, having trouble setting declaratively

    - by Chris McCall
    I'm developing a custom UserControl to inject JQuery hotkeys into a page declaratively on the server side. Here's the control (the important parts anyway): [AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal), AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal), DefaultProperty("HotKeys"), ParseChildren(true, "HotKeys"), ToolboxData("<{0}:HotKeysControl runat=\"server\"> </{0}:HotKeysControl>")] public partial class HotKeysControl : System.Web.UI.WebControls.WebControl { private string crlf = Environment.NewLine; public List<HotKey> _HotKeys; public HotKeysControl() { if (_HotKeys == null) { _HotKeys = new List<HotKey>(); } // if I uncomment this line, script is injected into the page // _HotKeys.Add(new HotKey("ctrl+r","thisControl")); } [ Category("Behavior"), Description("The hotkeys collection"), DesignerSerializationVisibility( DesignerSerializationVisibility.Content), Editor(typeof(HotKeyCollectionEditor), typeof(UITypeEditor)), PersistenceMode(PersistenceMode.InnerDefaultProperty) ] public List<HotKey> HotKeys { set { _HotKeys = value; } get { return _HotKeys; } } Here's the .aspx code: <%@ Register Assembly="MyCompany.ProductName.WebControls" Namespace="MyCompany.ProductName.WebControls" TagPrefix="uc" %> ... <uc:HotKeysControl ID="theHotkeys" runat="server" Visible="false"> <uc:HotKey ControlName="firstControl" KeyCode="ctrl+1" /> <uc:HotKey ControlName="thirdControl" KeyCode="ctrl+2" /> </uc:HotKeysControl> Nothing happens, as if no HotKeys objects are being added to the property collection. What Am I doing wrong? If I uncomment out the line above and "manually" add items, it works. It's something about how I'm declaratively adding hotkeys to the page. Any ideas?

  • Can Haskell's monads be thought of as using and returning a hidden state parameter?

    - by AJM
    I don't understand the exact algebra and theory behind Haskell's monads. However, when I think about functional programming in general I get the impression that state would be modelled by taking an initial state and generating a copy of it to represent the next state. This is like when one list is appended to another; neither list gets modified, but a third list is created and returned. Is it therefore valid to think of monadic operations as implicitly taking an initial state object as a parameter and implicitly returning a final state object? These state objects would be hidden so that the programmer doesn't have to worry about them and to control how they gets accessed. So, the programmer would not try to copy the object representing the IO stream as it was ten minutes ago. In other words, if we have this code: main = do putStrLn "Enter your name:" name <- getLine putStrLn ( "Hello " ++ name ) ...is it OK to think of the IO monad and the "do" syntax as representing this style of code? putStrLn :: IOState -> String -> IOState getLine :: IOState -> (IOState, String) main :: IOState -> IOState -- main returns an IOState we can call "state3" main state0 = putStrLn state2 ("Hello " ++ name) where (state2, name) = getLine state1 state1 = putStrLn state0 "Enter your name:"

  • Same Origin issue with web service call

    - by Wjdavis5
    My web server runs at http://mypc.com:80 ` Given the following snip: $(window).load(function () { var myURL = "http://mypc.com:8000/PSOCharts/service/HighChart_ColumnChart/i"; $.getJSON(myURL) .done(function(data) {alert(data);}); }); I am running to this error: XMLHttpRequest cannot load http://mypc.com:8000/PSOCharts/service/HighChart_ColumnChart/i. Origin http://mypc.com is not allowed by Access-Control-Allow-Origin. I understand why (I think) b/c my webservice runs at port 8000 which is different from what IIS is running on (port 80). I thought I could get around by using jsonp (according to the jQuery documentation here So I copied the example of making a call to the flickr api, but it isnt working. Any thoughts/sugggestions? UPDATE Ok so my request is being made now: var myURL = "http://192.168.1.104:8000/PSOCharts/service/HighChart_ColumnChart/i?jsoncallback=?"; $.ajax({ url :myURL, dataType: "jsonp", success: function(data) {a(data)} , error: function(){alert("err");}, }); But I am continually hitting the error function, here is what's being returned: [1.4,54.43,49.39,93.23] Now I'm assuming this is b/c the response text doesnt contain any type of callback here is the part of the interface I'm calling: [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "HighChart_ColumnChart/{id}?callback={cb}")] List<double> HighChart_ColumnChart(string id,string cb); Here is the actual function being called: public List<double> HighChart_ColumnChart(string id,string cb) { var z = new List<double>(); z.Add(1.4); z.Add(54.43); z.Add(49.39); z.Add(93.23); return z; } when I debug, the CB param is something like : "jQuery19108121746340766549_1372630643878". How do I modify the code to wrap it correctly? Thanks for the help thus far!

  • How to understand existing projects

    - by John
    Hi. I am a trainee developer and have been writing .NET applications for about a year now. Most of the work I have done has involved building new applications (mainly web apps) from scratch and I have been given more or less full control over the software design. This has been a great experience however, as a trainee developer my confidence about whether the approaches I have taken are the best is minimal. Ideally I would love to collaborate with more experienced developers (I find this the best was I learn) however in the company I work for developers tend to work in isolation (a great shame for me). Recently I decided that a good way to learn more about how experienced developers approach their design might be to explore some open source projects. I found myself a little overwhelmed by the projects I looked at. With my level of experience it was hard to understand the body of code I faced. My question is slight fuzzy one. How do developers approach the task of understanding a new medium to large scale project. I found myself pouring over lots of code and struggling to see the wood for the trees. At any one time I felt that I could understand a small portion of the system but not see how its all fits together. Do others get this same feeling? If so what approaches do you take to understanding the project? Do you have any other advice about how to learn design best practices? Any advice will be very much appreciated. Thank you.

  • Periodic GPU performance problem

    - by Peter Lillevold
    Hi folks! I have a WinForms application that uses XNA to animate 3D models in a control. The app have been doing just fine for months but recently I've started to experience periodic pauses in the animation. Setting out to investigate what is going on I have established these facts: It (currently) happens on my machine only Removing everything from my render loop does not improve the problem In 2. I didn't actually remove everything, I limited my loop to set the viewport on my GraphicsDevice and then do a GraphicsDevice.Present. Trying to dig further I fired up PIX to capture some statistics. Screenshots of two PIX runs can be viewed here (Run6) and here (Run14). Run6 is using my original render loop and Run14 is using the bare-bones Present loop. PIX tells me that the GPU is periodically doing something, and I assume this is causing the pauses. What could be the cause of this? Or how do I go about finding out what the GPU is actually doing? Note: I'm using XNA 3.1 on a Windows 7 x64 dual-core machine with 8GB RAM. Note2: also posted this question on the XNA Creators forums here.

  • How to Prevent PostBack Event Handler from Firing

    - by user331744
    I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

  • Advanced All In One .NET Framework (should i go for a software factory ?)

    - by alfredo dobrekk
    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration logging screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... At this point i have 3 options : Build from scratch on top of clr :( Find functionnalities among several open source framework and use them as a stack for infrastucture Find a "software factory" I know its lot but i really would like to use existing code to build upon so i can focus on business rules. What open source tools would u use to achieve these ?

  • A scripting engine for Ruby?

    - by Earlz
    Hello, I am creating a Ruby On Rails website, and for one part it needs to be dynamic so that (sorta) trusted users can make parts of the website work differently. For this, I need a scripting language. In a sort of similar project in ASP.Net, I wrote my own scripting language/DSL. I can not use that source code(written at work) though, and I don't want to make another scripting language if I don't have to. So, what choices do I have? The scripting must be locked down and not be able to crash my server or anything. I'd really like if I could use Ruby as the scripting language, but it's not strictly necessary. Also, this scripting part will be called on almost every request for the website, sometimes more than once. So, speed is a factor. I looked at the RubyLuaBridge but it is Alpha status and seems dead. What choices for a scripting language do I have in a Ruby project? Also, I will have full control over where this project is deployed(root access), so there are no real limits..

  • PHP IIS problems downloading file says it is corrupt

    - by Matt
    Hi, I am running PHP on IIS 6 with mssql. I have uploaded a file to my webserver through a php script. Upon checking the file on the server the file is ok and not corrupt. However, when i then have a link on my website to try and download the file, it says the file is corrupt. I know the file isnt corrupt as i can view it perfectly if i look at the file on the server. Is seems like this is a common problem as a similar problem was posted here: http://www.bigresource.com/Tracker/Track-php-1pAakBhT/ Any help would be much appreciated. Thanks, M My download code is as follows: $filesize = $rows->filesize; $filepath = $rows->filepath; header("Content-Disposition: attachment; filename=$filename"); header("Content-length: $filesize"); header("Content-type: application/pdf"); header("Cache-control: must-revalidate"); header("Content-Description: PHP Generated Data"); readfile($filepath);

  • Which cms or script for social network wiki?

    - by Jason
    Hi, I am building a social network. I need a cms that will allow users to contribute content. Each content item will need to have a google map, list of features, ratings, comments, etc. And the content must be editable by other users with revision control. Also, each user should have a profile with their bookmarked content items, contributed items, comments, etc. It's very important that I can create a template for the wiki/content entries so that each item looks uniform. (and as a kick in the teeth, I would like to be able to search for wiki items using a radial search or map) Joomla was my first choice, as I've used it for many projects, but the wiki functionality is not there. I was also setting up a grou.ps site, but the wiki is so-so - not feature rich and it really doesn't have the option I need. Additionally, I know someone out there will mention Drupal. I may consider it if I can see it put to use without and overabundance of custom programming (I don't mind initial coding, but drupal requires constant coding & recoding - with this site, I dont' have that time commitment) I thought about using mediawiki with buddypress, but i'm not sure if that's the way to go. Thoughts?

  • What causes markup-controls to be null?

    - by Earlz
    Ok, I have a very strange problem. I have a regular UserControl with some controls in the markup. At Page_Load these controls are still null. And I have tried EnsureChildControls It is laid out like this: Masterpage - Page - mycontrol1 - mycontrol2 - problemcontrol ProblemControl is where the controls are null. MyControl1 contains MyControl2. MyControl2 is another UserControl which contains ProblemControl in it's markup. Masterpage is nothing special and Page contains MyControl1 in it's markup. The only oddity is that ProblemControl is created dynamically at Page_Init. Everything works fine until I get to ProblemControl where none of the controls are being created. ProblemControl has the proper things all set such as the Page and Parent property. I do not see any problems. The source code for all of these(except ProblemControl) is pretty extensive, so I'm hoping someone can just give me some troubleshooting tips for this problem and if anyone has encountered it before. Also, I can place ProblemControl on another Page control and it will work fine, it's something about mycontrol1 and/or mycontrol2. But we've never had any problems with mycontrol1 and mycontrol2 doesn't have anything I can see wrong with it. (which I've been tediously analyzing for the past few hours). Has anyone else had this same problem? Are there any common things to check for?

  • Resources for setting up a Visual Studio/C++ development environment

    - by Tom H.
    I haven't done much "front-end" development in about 15 years since moving to database development. I'm planning to start work on a personal project using C++ and since I already have MSDN I'll probably end up doing it in Visual Studio 2010. I'm thinking about using Subversion as a version control system eventually. Of course, I'd like to get up and running as quickly as I can, but I'd also like to avoid any pitfalls from a poorly organized project environment. So, my question is, are there any good resources with common best practices for setting up a development environment? I'm thinking along the lines of where to break down a solution into multiple projects if necessary, how to set up a unit testing process, organizing resources, directories, etc. Are there any great add-ons that I should make sure I have set up from the start? Most tutorials just have one simple project, type in your code and click on build to see that your new application says, "Hello World!". This will be a Windows application with several DLLs as well (no web development), so there doesn't need to be a deploy to a web server kind of process. Mostly I just want to make sure that I don't miss anything big and then have to extensively refactor because of it. Thanks!

  • Bind to a markup externsion property

    - by user314580
    Hi, I have written a markup extension which stores amongst others a help text. This help text is shown on the right side of the main window. This works fine. Now, I want to add a tooltip for every control. The content of the tooltip should be same as for the helptext extension. The XAML code: <ListView ctrl:ListViewLayoutManager.Enabled="true" x:Name="ListViewSources" ItemsSource="{Binding SourceItems}" ItemContainerStyle="{DynamicResource ListViewItemStyleAlternate}" Height="150" MinWidth="350" Helper:HelpExtension.IsControl="true" Helper:HelpExtension.HelpText="{x:Static strings:GUIResource.HelpProfilesSourcesDescriptionText}" > <ListView.ToolTip> <ToolTip Style="{DynamicResource Own_TooltipStyle}"></ToolTip> </ListView.ToolTip> And now the code of the style: If I run the program I get the binding error: System.Windows.Data Error: 39 : BindingExpression path error: 'Helper:HelpExtension' property not found on 'object' ''ListView' (Name='ListViewSources')'. BindingExpression:Path=Helper:HelpExtension.HelpText; DataItem='ListView' (Name='ListViewSources'); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String') Does anybody know how I can bind the TextBlock to the content of Helper:HelpExternsion.HelpText?

  • On checkbox checked show radio button

    - by aDameToKillFor
    Hello, I would like to ask for a little help here, since I haven't got any big knowledge in Javascript, nor in jQuery. I need to show 5 radio buttons when a checkbox is checked, the checkboxes represent languages that the user speaks, so for each of the selected, there should appear 5 separate radio buttons for how good they speak it(1 to 5). I tried to do it with jQuery, but I did not manage to get very far away... This is where my checkboxes are created(dynamically): <% for(int i = 0; i < Model.Languages.Count; i++) { %> <input id="applang" name="applang" type="checkbox" value="<%: Model.Languages[i].languageID%>" /> <%: Model.Languages[i].name.ToString() %><br /> <%} %> So, I tried to add this script, but it's not working: <script type="text/javascript"> $("input[@name='applang']").click(function () { $("input[type='radio']").show(); }); I also tried this way - to use this javascript: <script type="text/javascript"> function toggle_visibility(id) { var e = document.getElementById(id); if (e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; } And it works, but it works on already present controls, and I guess I need to create mine dynamically, or maybe not? And I tried to hide a present control with CSS, but then when the script shows it, it is there, only invisible :) Also, I would want to get the name and value of the radio buttons from my database, i.e. Model(this is ASP.NET MVC).. Can someone help me a little bit, please?

  • Re-authentication required for registered-path links (to ASP.NET site) coming to IE from PowerPoint

    - by Daniel Halsey
    We're using URL routing based on Phil Haack's example, with config modifications based on MSDN Library article #CC668202, to provide "shareable" links for a ASP.NET forms site, and have run into a strange issue: For users attempting to open links from PowerPoint presentations, and who have IE set as their default browser, using one of these links forces (forms-based) re-authentication, even in the same browser instance with a live session. Info: We know the session is still alive. (Page returns information for the currently logged-in user; confirmed via debug watches) This doesn't happen with other browsers (FF, Chrome) or with other programs (Notepad++) as the URL source. We do not have a default path set, as this caused issues with root path handling at initial login. This primarily happens with PowerPoint, but will also happen in Word and OCS. On some machines, even after changing the default browser, Office apps will continue to use IE for these links, forcing this error. (A potential registry fix for this failed, but even if it had worked, we can't control default browser choice for our users.) We can't figure out if this is an Office oddity or is being caused by our decision to use app-level URL routing (rather than IIS rewriting). Has anyone else encountered this and found a solution?

  • How to make a controls compliant for winform and webform?

    - by Martijn
    In my application I have methods which returns a control (checkbox, radiobutton, textbox) but I want to use the same class for my webform and winform. How can I achieve this? I was thinking about an interface, but I don't know how to implement this. In my code I have the following methods: public TextBox GenerateTextfield(AnswerPossibility answerPossibility) { TextBox textBox = new TextBox(); textBox.Tag = answerPossibility.Tag; return textBox; } public Collection<ButtonBase> GenerateMultipleChoice(Collection<AnswerPossibility> answers) { Collection<ButtonBase> checks = new Collection<ButtonBase>(); foreach (AnswerPossibility a in answers) { CheckBox chk = new CheckBox(); chk.Text = a.Text; chk.Name = "chk" + a.Id.ToString(); chk.Tag = a.Tag; checks.Add(chk); } return checks; } How can I make this so, that I can use this methods in a win form as well in a web form?

  • Thumbnail image saved with worse quality on Windows Server 2003

    - by Angelo
    Hello, In asp.net 2.0 application I am trying to create thumbnails from uploaded images. However when I test the application on my PC under Windows7 it works fine, but on the real Windows 2003 Server the resized image has worse quality. Where this difference could come from? Different JPEG codec or what, if Yes how it can be updated on Win 2003 Server? Thanks! Here is the code: Resize of the Image: Bitmap newBmp = new Bitmap(imgWidth, imgHeight, PixelFormat.Format24bppRgb); newBmp.SetResolution(inputBmp.HorizontalResolution, inputBmp.VerticalResolution); //Create a graphics object attached to the new bitmap Graphics newBmpGraphics = Graphics.FromImage(newBmp); newBmpGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic; newBmpGraphics.SmoothingMode = SmoothingMode.HighQuality; newBmpGraphics.PixelOffsetMode = PixelOffsetMode.HighQuality; newBmpGraphics.DrawImage(inputBmp, new Rectangle(0, 0, imgWidth, imgHeight), new Rectangle(0, 0, inputBmp.Width, inputBmp.Height), GraphicsUnit.Pixel); Save of the Image: System.IO.Stream imgStream = new System.IO.MemoryStream(); //Get the ImageCodecInfo for the desired target format ImageCodecInfo destCodec = FindCodecForType(ImageMimeTypes.JPEG); if (destCodec == null) { //No codec available for that format throw new ArgumentException("The requested format image/jpeg does not have an available codec installed", "destFormat"); } //Create an EncoderParameters collection to contain the //parameters that control the dest format's encoder EncoderParameters destEncParams = new EncoderParameters(1); EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality,(long)quality); destEncParams.Param[0] = qualityParam; //Save w/ the selected codec and encoder parameters inputBmp.Save(imgStream, destCodec, destEncParams); Bitmap destBitmap = new Bitmap(imgStream);

  • Mono Text Based Web Browser

    - by powerbox
    Hi guys, is there any public text based web browser implementation for C# or on mono base api that I can use to fill up web forms automatically? I'll be using it to automate some web task that does not require any image authentication. I'm currently using a web browser control available on .Net Framework and waits for the event WebBrowserDocumentCompletedEventHandler to fire after a page is successfully loaded and invoke some actions like Submit or simulating a mouse click on some links. It actually does the job but I can't process bulk transactions since I needed to wait for the whole page to be loaded together with the images and other stuff. It is easy to use HttpWebRequest to fill up some forms , provide some data and then submit. But on some occasions I only need to simulate a mouse click to a certain link which I don't know how to do with HttpWebRequest. By the way using HttpWebRequest will still download all the images of a web page that I see pointless since I only need to provide correct data back to the server. I hope someone can pinpoint me the correct way of doing this kind of automation and thanks in advance!

  • PC boot: dl register and drive number

    - by kikou
    I read somewhere in the internet that, before jumping to 0x7c00, the BIOS loads into %dl the "drive number" of the booted device. But what is this "drive number"? Each device attached to the computer is assigned a number by the BIOS? If so, how can I know which number is a given device assigned to? Reading GRUB's source code I found when %dl has bits 0x80 and 0x70 set, it overwrites the whole register with 0x80. Why is that? Here is the code: jmp 3f /* grub-setup may overwrite this jump */ testb $0x80, %dl jz 2f 3: /* Ignore %dl different from 0-0x0f and 0x80-0x8f. */ testb $0x70, %dl jz 1f 2: movb $0x80, %dl 1: By the way. Is there any detailed resource on the boot process of PC's in the web? Specially about what the BIOS does before giving the control to the bootloader and also the standard codes used to communicate with it (like that "drive numer"). I was hoping to write my own bootloader and everything I found is a bit too vague, not technical enough to the point of informing of the exact state of the computer when my bootloader starts to run.

  • Can I write a .NETCF Partial Class to extend System.Windows.Forms.UserControl?

    - by eidylon
    Okay... I'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea. There are certain methods and properties these controls all need to work within the app. Right now I am doing this as an Interface, but this is aggravating as all get up, because some of the methods are optional, and yet I MUST implement them by the nature of interfaces. I would prefer to use inheritance, so that I can have certain code be inherited with overridability, but if I write a class which inherits System.Windows.Forms.UserControl and then inherit my control from that, it squiggles, and tells me that UserControls MUST inherit directly from System.Windows.Forms.UserControl. (Talk about a design flaw!) So next I thought, well, let me use a partial class to extend System.Windows.Forms.UserControl, but when I do that, even though it all seems to compile fine, none of my new properties/methods show up on my controls. Is there any way I can use partial classes to 'extend' System.Windows.Forms.UserControl? For example, can anyone give me a code sample of a partial class which simply adds a MyCount As Integer readonly property to the System.Windows.Forms.UserControl class? If I can just see how to get this going, I can take it from there and add the rest of my functionality. Thanks in advance! I've been searching google, but can't find anything that seems to work for UserControl extension on .NET CF. And the Interface method is driving me crazy as even a small change means updating ALL the controls whether they need to 'override' the method or not.

  • ctrl+click or shift+click not always firing the onclick event

    - by Erik
    Hi, I recently discovered that different browsers handle the onclick event differently when the control of shift key is pressed. Same thing for following links with the middle mouse button. <a href="http://www.example.com/" onclick="alert('onclick');">go to example.com</a> Onclick browser support table Mouse Keyboard Chrome Firefox Safari Opera IE5.5 IE6 IE7 IE8 IE9 Left None yes yes yes yes yes yes yes yes yes Left Ctrl yes yes yes yes ? yes no no ? Left Shift yes yes yes yes ? yes yes yes ? Middle None yes no yes no ? N/A no no ? Can someone please fill in the question marks for me? Also; I'm wondering if the behaviour differs for each version of Chrome, Firefox, Safari and Opera. Finding a logical pattern in this behaviour would be even nicer, but I don't think there is :). Thanks a lot.
