• Flex 3 - Scroll bar issue

  - by Emma

  Im currently learning Flex, and Im having the hardest time getting scroll bars to work. In short Im pretty much just making a giant form for users to fill out, contained within a viewstack component, the user will type up information in one view, and it will be displayed in the other. But right now in the first canvas i have components that run of the screen and flex doesnt seem to automate a scroll bar, so i added in 'verticalScrollPolicy="on"' to my canvas, now while it gives me a scroll bar, it gives me an empty scroll bar, I still cannot move it up or down, meaning components are still trapped off the bottom of my screen. Im I missing something amazingly simple? Edit - Sorry, Im using Adobe Flex Builder 3, and the components it lets you drag in. http://img12.imageshack.us/img12/218/problem1f.jpg This is a picture of the problem, and i guess relavent code would be. <mx:Application xmlns:mx="adobe.com/2006/mxml"; layout="absolute" width="830" height="835"> <mx:ViewStack x="10" y="72" id="viewstack1" width="790" height="751" > <mx:Canvas label="Design Mode" width="100%" height="100%" verticalScrollPolicy="on" horizontalScrollPolicy="on" > (Components inside) </mx:Canvas> Sorry if Im using this site wrong, still very new

• Rendering PDFs from a database inside MVC views?

  - by Mohammad Sepahvand

  I was wondering if it's possible to do this without using 3rd party compnents in MVC 3. (I am open to free components though.) There are a couple of links out there but they seem to be mostly concerned with reporting and other code samples that do claim to do this sort of thing don't seem to compile. I'm not having any trouble saving and retrieving the PDFs to and from my database, but when I return the PDF as a File or a FileStreamResult the user is prompted with a download. A more desirable approach would be to actually render the PDFs inside the browser. I've had a look at iTextSHarp, it does the job to an extent, but it's not a complete solution. For example it will display the PDF inside the view if and only if the client has Adobe Reader installed, otherwise it prompts for a download. So technically, I'm mostly looking for a PDF viewer. Any ideas?

• using ontouch to zoom in

  - by user357032

  i have used some sample code and am trying to tweak it to let me allow the user to touch the screen and zoom in the code runs fine with no errors but when i touch the screen nothing happens package com.thomas.zoom; import android.content.Context; import android.graphics.Canvas; import android.graphics.drawable.Drawable; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; public class Zoom extends View { private Drawable image; private int zoomControler=20; public Zoom(Context context) { super(context); image=context.getResources().getDrawable(R.drawable.icon); setFocusable(true); } @Override protected void onDraw(Canvas canvas) { // TODO Auto-generated method stub super.onDraw(canvas); //here u can control the width and height of the images........ this line is very important image.setBounds((getWidth()/2)-zoomControler, (getHeight()/2)-zoomControler, (getWidth()/2)+zoomControler, (getHeight()/2)+zoomControler); image.draw(canvas); } public boolean onTouch(int action, MotionEvent event) { action= event.getAction(); if(action == MotionEvent.ACTION_DOWN){ zoomControler+=10; } invalidate(); return true; } }

• VLC desktop streaming

  - by StackedCrooked

  Edit I stopped using VLC and switched to GMax FLV Encoder. It does a much better job IMO. Original post I am sending my desktop (screen) as an H264 video stream to another machine that saves it to a file using the follwoing command lines: Sender of the stream: vlc -I dummy --sout='#transcode{vcodec=h264,vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' Receiver of the stream: vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}' --ipv4 This works, but there are a few issues: The file is not playable with most players. VLC is able to playback the file but with some weirdness: = it takes about 10 seconds before the playback actually begins. = seeking doesn't work. Can someone point me in the right direction on how to fix these issues? EDIT: I made a little progress. The initial delay in playback is because the player is waiting for a keyframe. By forcing the sender of the stream to create a new key-frame every 4 seconds I could decrease the delay: :screen-fps=10 --sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' The seeking problem is not solved however, but I understand it a little better. The RTP stream is saved as a file in its original streaming format, which is normally not playable as a regular video file. VLC manages to play this file, but most other players don't. So I need to convert it to a regular video file. I am currently investigating whether I can do this with ffmpeg if I provide it with an SDP file for the recorded stream. All help is welcome!

• Redraw and flicker issues

  - by AngryHacker

  I have an Outlook style app. So basically I have a sidebar on the left and on the right I have a panel control (pnlMainBody) that hosts content. The content is typically a user control that I add to the panel when user clicks appropriate button in the side bar. The way I add the user control to the panel is as follows: // _pnlEmails is the User Control that I am adding to the panel _pnlEmails = new pnlEmails(); _pnlEmails.Dock = DockStyle.Fill; this.pnlMainBody.Controls.Add(_pnlEmails); Some of the user controls that I add to the main panel are quite complex UI-wise. So when this.pnlMainBody.Controls.Add(_pnlEmails); fires, I see the control appear on the screen, then it resizes itself to fill the body of the panel control. It's quite ugly actually, so I was wondering whether there is a way to not show the resizing until it's actually done resizing? I've tried setting the user control's .Visible to false. I've tried doing .SuspendLayout, all to no avail. Is there a way to do this so the screen transitions are smooth?

• How to detect if a page is an RSS or ATOM feed

  - by Pepper

  Hello, I'm currently building a new online Feed Reader in PHP. One of the features i'm working on is feed auto-discovery. If a user enters a website URL, the script will detect that its not a feed and look for the real feed URL by parsing the HTML for the proper tag. The problem is, the way im currently detecting if the URL is a feed or a website only works part of the time, and I know it can't be the best solution. Right now im taking the CURL response and running it through simplexml_load_string, if it can't parse it I treat it as a website. Here is the code. $xml = @simplexml_load_string( $site_found['content'] ); if( !$xml ) // this is a website, not a feed { // handle website } else { // parse feed } Obviously, this isn't ideal. Also, when it runs into an HTML website that it can parse, it thinks its a feed. Any suggestions on a good way of detecting the difference between a feed or non-feed in PHP? Thanks, Pepper http://feedingo.com

• Seperation of game- and rendering logic

  - by Qua

  What is the best way to seperate rendering code from the actually game engine/logic code? And is it even a good idea to seperate those? Let's assume we have a game object called Knight. The Knight has to be rendered on the screen for the user to see. We're now left with two choices. Either we give the Knight a Render/Draw method that we can call, or we create a renderer class that takes care of rendering all knights. In the scenario where the two is seperated the Knight should the knight still contain all the information needed to render him, or should this be seperated as well? In the last project we created we decided to let all the information required to render an object be stored inside the object itself, but we had a seperate component to actually read those informations and render the objects. The object would contain information such as size, rotation, scale, and which animation was currently playing and based on this the renderer object would compose the screen. Frameworks such as XNA seem to think joining the object and rendering is a good idea, but we're afraid to get tied up to a specific rendering framework, whereas building a seperate rendering component gives us more freedom to change framework at any given time.

• CQRS - The query side

  - by mattcodes

  A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

• how to insert multiple rows using cakephp

  - by Paul

  In the cakePHP project I'm building, I want to insert a defined number of identical records. These will serve as placeholders records that will have additional data added later. Each record will insert the IDs taken from two belongs_to relationships as well as two other string values. What I want to do is be able to enter a value for the number of records I want created, which would equate to how many times the data is looped during save. What I don't know is: 1) how to setup a loop to handle a set number of inserts 2) how to define a form field in cakePHP that only sets the number of records to create. What I've tried is the following: function massAdd() { $inserts_required = 1; while ($inserts_required <= 10) { $this->Match->create(); $this->Match->save($this->data); echo $inserts_required++; } $brackets = $this->Match->Bracket->find('list'); $this->set(compact('brackets')); } What happens is: 1) at the top of the screen, above the doc type, the string 12345678910 is displayed, this is displayed on screen 2) a total of 11 records are created, and only the last record has the values passed in the form. I don't know why 11 records as opposed to 10 are created, and why only the last records has the entered form data? As always, your help and direction is appreciated. -Paul

• How to stop NpgsqlDataReader from blocking?

  - by Swingline Rage

  Running the following code against a large PostgreSQL table, the NpgsqlDataReader object blocks until all data is fetched. NpgsqlCommand cmd = new NpgsqlCommand(strQuery, _conn); NpgsqlDataReader reader = cmd.ExecuteReader(); // <-- takes 30 seconds How can I get it to behave such that it doesn't prefetch all the data? I want to step through the resultset row by row without having it fetch all 15 GB into memory at once. I know there were issues with this sort of thing in Npgsql 1.x but I'm on 2.0. This is against a PostgreSQL 8.3 database on XP/Vista/7. I also don't have any funky "force Npgsql to prefetch" stuff in my connection string. I'm at a complete loss for why this is happening.

• Textured Primitives in XNA with a first person camera

  - by 131nary

  So I have a XNA application set up. The camera is in first person mode, and the user can move around using the keyboard and reposition the camera target with the mouse. I have been able to load 3D models fine, and they appear on screen no problem. Whenever I try to draw any primitive (textured or not), it does not show up anywhere on the screen, no matter how I position the camera. In Initialize(), I have: quad = new Quad(Vector3.Zero, Vector3.UnitZ, Vector3.Up, 2, 2); quadVertexDecl = new VertexDeclaration(this.GraphicsDevice, VertexPositionNormalTexture.VertexElements); In LoadContent(), I have: quadTexture = Content.Load<Texture2D>(@"Textures\brickWall"); quadEffect = new BasicEffect(this.GraphicsDevice, null); quadEffect.AmbientLightColor = new Vector3(0.8f, 0.8f, 0.8f); quadEffect.LightingEnabled = true; quadEffect.World = Matrix.Identity; quadEffect.View = Matrix.CreateLookAt(cameraPosition, cameraTarget, Vector3.Up); quadEffect.Projection = this.Projection; quadEffect.TextureEnabled = true; quadEffect.Texture = quadTexture; And in Draw() I have: this.GraphicsDevice.VertexDeclaration = quadVertexDecl; quadEffect.Begin(); foreach (EffectPass pass in quadEffect.CurrentTechnique.Passes) { pass.Begin(); GraphicsDevice.DrawUserIndexedPrimitives<VertexPositionNormalTexture>( PrimitiveType.TriangleList, quad.Vertices, 0, 4, quad.Indexes, 0, 2); pass.End(); } quadEffect.End(); I think I'm doing something wrong in the quadEffect properties, but I'm not quite sure what.

• How to encorporate encyption to FlexPaper

  - by Jonathan

  Is it possible to configure the FlexPaper reader to un-encrypt password-protected pdfs or swfs? Here is the use-case: User uploads a pdf My server would then convert the pdf to swf via pdf2swf Then somehow encrypt the swf with a password (not sure best way to do this) Then the FlexPaper would be able to un-encrypt the swf and display it What I am trying to avoid is the caching of readable swf in the browser's cache. Any ideas on the best way to achieve this? I know, even with this it will not be a fully secure solution, but certainly helps. Note: I am running this on Linux and OS X and using Rails. Thanks!

• Bare-metal virtualisation for the desktop

  - by Andrew Taylor

  Hi, Does anyone have any knowledge about bare-metal virtualisation products? I'm interested in building a new desktop machine for home, I've been looking at the Intel Quad Core processors and I'd like to put 8GB of RAM in there, but, it got me thinking about making the most out of the available resources. I thought if I could get a good 64bit machine, put some bare-metal virtualisation on, then have a primary system, I'd also be able to bring up some extra virtualised systems as and when I needed. I know most of the bare metal systems are designed for the server market, but, is there anything out there that works well for a desktop. What are the caveats? I presume I won't be able to make the most out of any video cards I could buy, what about just getting a decent screen resolution, will this be a problem? I run a single 24" screen. What about DVD/CD writing, is this possible? I'd like to re-rip my CD collection, I was hoping the quad 64Bit goodness would help me out with the encoding. I currently use a Mac and couldn't go back to windows so that leaves Linux, I was thinking a primary OS of ubuntu. Does this make a difference? Thanks Andrew

• Are these tables respect the 3NF Database Normalization?

  - by penas

  AUTHOR table Author_ID, PK First_Name Last_Name TITLES table TITLE_ID, PK NAME Author_ID, FK DOMAIN table DOMAIN_ID, PK NAME TITLE_ID, FK READERS table READER_ID, PK First_Name Last_Name ADDRESS CITY_ID, FK PHONE CITY table CITY_ID, PK NAME BORROWING table BORROWING_ID,pk READER_ID, fk TITLE_ID, fk DATE HISTORY table READER_ID TITLE_ID DATE_OF_BORROWING DATE_OF_RETURNING Are these tables respect the 3NF Database Normalization? What if 2 authors work together for the same title? The column Addresss should have it's own table? When a reader borrows a book, I make an entry in BORROWING table. After he returns the book, I delete that entry and I make another one entry in HISTORY table. Is this a good idea? Do I brake any rule? Should I have instead one single BORROWING table with a DATE_OF_RETURNING column?

• Circular Dependency Solution

  - by gfoley

  Our current project has ran into a circular dependency issue. Our business logic assembly is using classes and static methods from our SharedLibrary assembly. The SharedLibrary contains a whole bunch of helper functions, such as a SQL Reader class, Enumerators, Global Variables, Error Handling, Logging and Validation. The SharedLibrary needs access to the Business objects, but the Business objects need access to SharedLibrary. The old developers solved this obvious code smell by replicating the functionality of the business objects in the shared library (very anti-DRY). I've spent a day now trying to read about my options to solve this but i'm hitting a dead end. I'm open to the idea of architecture redesign, but only as a last resort. So how can i have a Shared Helper Library which can access the business objects, with the business objects still accessing the Shared Helper Library?

• TextRenderer.DrawText renders Arial differently on XP vs Vista

  - by Michael

  I have a c# application that does text rendering, something on par with a simple wysiwyg text editor. I'm using TextRenderer.DrawText to render the text to the screen and GetTextExtentPoint32 to measure text so I can position different font styles/sizes on the same line. In Vista this all works fine. In XP however, Arial renders differently, certain characters like 'o' and 'b' take up more width than in Vista. GetTextExtentPoint32 seems to be measuring the string as it would in Vista though, with the smaller widths. The end result is that every now and then a run of text will overlap the text preceding it because the preceding text gets measured as smaller than it actually is on the screen. Also, my text rendering code mimics ie's text rendering exactly (for simple formatting and english language only) and ie text rendering seems to be consistent between vista and xp - that's how I noticed the change in size of the different characters. Anyone have any ideas about what's going on? In short, TextRenderer.DrawText and GetTextExtentPoint32 don't match up in xp for Arial. DrawText seems to draw certain characters larger and/or smaller than it does in Vista but GetTextExtentPoint32 seems to be measuring the text as it would in Vista (which seems to match the text rendering in ie on both xp and vista). Hope that makes sense. Note: unfortunately TextRenderer.MeasureString isn't fast or accurate enough to meet my requirements. I tried using it and had to rip it out.

• Issue reading packets from a pcap file. dpkt module. What gives?

  I am running the following test script to try to read packets from a sample .pcap file I have downloaded. It won't seem to run.

• Embedded Vimeo Video Callbacks

  - by Andrew

  This post is kind of a follow up to a post I made earlier in regards to HTML5 video callbacks. In that thread, I was given a great piece of code that would allow for the browser to be informed of when the video stops playing and then fire off an action (with jQuery). This is the code I'm currently using: $('video.normal').bind('ended', function(){ $(this).fadeOut().queue(function(){ $(this).siblings('.post-video').fadeIn(); $(this).dequeue(); }); }); Which basically fades the video out when it's completed and brings a poster frame of the video (or similar image) back into view. Well, the scope of the project has changed and now the client is asking for true full screen video and different size videos to be delivered based on user connection speed, something that's a little over my head and a lot over budget. So I've been researching and a Vimeo Plus player seems like a great alternative for visitors using a desktop browser (HD embeds, true full screen, and more). Thing is, I need that above code to continue working in some capacity or another, so does the embedded Vimeo player offer a similar callback that I can utilize? Or am I SOL here? Thanks in advance!

• What's the best way to read/write array contents from/to binary files in C#?

  - by Eric

  I would like to read and write the contents of large ( 2GB), raw volume files (e.g. MRI scans). These files are just a sequence of e.g. 32 x 32 x 32 floats so they map well to 1D arrays. I would like to be able to read the contents of the binary volume files into 1D arrays of e.g. float or ushort (depending on the data type of the binary files) and similarly export the arrays back out to the raw volume files. What's the best way to do this with C#? Read/Write them 1 element at a time with BinaryReader/BinaryWriter? Read them piece-wise into byte arrays with FileStream.Read and then do a System.Buffer.BlockCopy between arrays (keeping in mind that I want 2GB arrays)? Write my own Reader/Writer?

• Resizing video best practices (frame size)

  - by undefined

  I have read the following which is from Best Practices for Encoding Video with the VP6 Codec on the Adobe website here - http://www.adobe.com/devnet/flash/articles/encoding_video_print.html. It is talking about common video ratios (320x240, 640x480) Although these ratios are standard, and should be used to avoid distorting the video, the size of the encoded video is not set in stone. The original web video sizes used heights and widths that were evenly divisible by 16. This was mandatory for many early codecs. Although this is not necessary for modern codecs, you should stick to even heights and widths. What do they mean by 'even heights and widths'. I am thinking about encoding my video at 400x300 to make it slightly bigger, this is still 4x3 format but should I just stick at 320x240 and resize it on the screen? Clearly there are benefits to this in terms of storage size and delivery costs. In some places on my site I want to show the video at 400x300 but in others I want it to play full screen so this is why I am wondering if a larger original size (400x300) will give better results when blown up. Any thoughts?

• pdf errors with php, apache2

  - by julio

  Hi-- I'm seeing some strange behavior from some dynamically generated PDFs using the TCPDF library in PHP. Standard lamp stack-- however, if you try to open the PDF from Windows with Acrobat Reader, it gives an error that the "file is damaged and could not be repaired". From Mac, Linux, etc. the file works fine, and opens fine. It also opens fine in Google Docs-- so clearly the PDF itself is ok. Is it possible that the mime type (application/pdf) is causing problems in Windows? Thanks

• How can I access the bookmarks toolbar using only shortcuts in Firefox 3

  I am not interested in accessing the bookmarks menu or sidebar. The specific goal that I'm trying to accomplish is to be able to easily navigate (using only the keyboard) through the live bookmarks loaded from stack overflow by means of a feed reader and located on my bookmarks toolbar. Notes: I have found an add-on that supposedly does exactly what I need: Bookmark Keys, but unfortunately it doesn't work in firefox 3), and is not being currently maintained. I'm using WinXP at work and Ubuntu 8.04 at home. Edit: changed bookmark keys "not compatible" with firefox 3 to "not working" in firefox 3
