  • Devision in c# not going the way i expect

    - by Younes
    Im trying to write something to get my images to show correctly. I have 2 numbers "breedtePlaatje" and "hoogtePlaatje". When i load those 2 vars with the values i get back "800" and "500" i expect "verH" to be (500 / 800) = 0,625. Tho the value of verH = 0.. This is the code: int breedtePlaatje = Convert.ToInt32(imagefield.Width); int hoogtePlaatje = Convert.ToInt32(imagefield.Height); //Uitgaan van breedte plaatje if (breedtePlaatje > hoogtePlaatje) { double verH = (hoogtePlaatje/breedtePlaatje); int vHeight = Convert.ToInt32(verH * 239); mOptsMedium.Height = vHeight; mOptsMedium.Width = 239; //Hij wordt te klein en je krijgt randen te zien, dus plaatje zelf instellen if (hoogtePlaatje < 179) { mOptsMedium.Height = 179; mOptsMedium.Width = 239; } } Any tips regarding my approach would be lovely aswell.

  • content show problem

    - by nonab
    I still fight with some jquery scripts:) With my first problem Jens Fahnenbruck helped me here: http://stackoverflow.com/questions/3021476/problem-with-hide-show-in-jquery thanks:) Now i added another fancy thing - jquery tabs Made a few modifications and it works like this: When you click on tab and it loads different main image for every tab. The problem is that i used $(document).ready(function() to handle those image changes. When i click any of 2x2 box images (on any tab) it will permanently change the image on the right and when i click on tabs it won't work like it did at the beginning. online example: http://rarelips.ayz.pl/testy/2/ code: <style type="text/css"> body { font: Arial, Helvetica, sans-serif normal 10px; margin: 0; padding: 0; } * {margin: 0; padding: 0;} img {border: none;} .container { height: 500px; width: 1000px; margin: -180px 0 0 -450px; top: 50%; left: 50%; position: absolute; } ul.thumb { float: left;

  • Java BufferedWriter close()

    - by rakeshr
    Hi, assume that I have the following code fragment operation1(); bw.close(); operation2(); When I call BufferedReader.close() from my code, I am assuming my JVM makes a system call that ensures that the buffer has been flushed and written to disk. I want to know if close() waits for the system call to complete its operation or does it proceed to operation2() without waiting for close() to finish. To rephrase my question, when I do operation2(), can I assume that bw.close() has completed successfully?

  • Java Convert ColorSpace of BufferedImage to CS_GRAY without using ConvertColorOp

    - by gmatt
    I know its possible to convert an image to CS_GRAY using public static BufferedImage getGrayBufferedImage(BufferedImage image) { BufferedImageOp op = new ColorConvertOp(ColorSpace .getInstance(ColorSpace.CS_GRAY), null); BufferedImage sourceImgGray = op.filter(image, null); return sourceImgGray; } however, this is a chokepoint of my entire program. I need to do this often, on 800x600 pixel images and takes about 200-300ms for this operation to complete, on average. I know I can do this alot faster by using one for loop to loop through the image data and set it right away. The code above on the other hand constructs a brand new 800x600 BufferedImage that is gray scale. I would rather just transform the image I pass in. Does any one know how to do this with a for loop and given that the image is RGB color space?

  • Checking whether an object exists in StructureMap container

    - by Kevin Pang
    I'm using StructureMap to handle the creation of NHibernate's ISessionFactory and ISession. I've scoped ISessionFactory as a singleton so that it's only created once for my web app and I've scoped ISession as a hybrid so that it will only be opened once per web request. I want to make sure that at the end of each web request, I properly dispose of ISession if it was created for that web request. I figured I could put some code in my Application_EndRequest routine to first check if an ISession was created, and if so, call ISession.Dispose. My current workaround is to just open up an ISession on Application_BeginRequest then dispose of it on Application_EndRequest, but that seems somewhat wasteful in that static file requests for images and css files and whatnot will create an ISession without ever using it. I know that the overall performance hit is negligable since ISessions are very lightweight, but it's getting annoying seeing all those ISessions being created inside NHProf.

  • PDF text search and split library

    - by Horace Ho
    I am look for a server side PDF library (or command line tool) which can: split a multi-page PDF file into individual PDF files, based on a search result of the PDF file content Examples: Search "Page ???" pattern in text and split the big PDF into 001.pdf, 002,pdf, ... ???.pdf A server program will scan the PDF, look for the search pattern, save the page(s) which match the patten, and save the file in the disk. It will be nice with integration with PHP / Ruby. Command line tool is also acceptable. It will be a server side (linux or win32) batch processing tool. GUI/login is not supported. i18n support will be nice but no required. Thanks~

  • SDL_BlitSurface() not displaying image?

    - by Christian Gonzalez
    So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed.

  • Optimize loading an XAP file with an asp.net website

    - by theoneawaited
    I've been developing a game using Silverlight 4 and silversprite (http://silversprite.codeplex.com/) This game is HEAVILY content dependent, using a lot of audio and images. My content folder is around 90 mbs worth of stuff. And because of that, my XAP file is around 60 MB, and takes 5 minutes to download from the website before any user can start playing. I am using Visual Web Developer 2010 to create my site and load the XAP. Is there a way where I can take content out of my XAP and put it in my ASP.net site project? Or perhaps upload my content files to the site's storage? This would make my XAP file much quicker to download. Anyone have suggestions? Thanks!

  • Regex: absolute url to relative url (C#)

    - by splatto
    I need a regex to run against strings like the one below that will convert absolute paths to relative paths under certain conditions. <p>This website is <strong>really great</strong> and people love it <img alt="" src="http://localhost:1379/Content/js/fckeditor/editor/images/smiley/msn/teeth_smile.gif" /></p> Rules: - If the url contains "/Content/" I would like to get the relative path - If the url does not contain "/Content/", it is an external file, and the absolute path should remain Regex unfortunatley is not my forte, and this is too advanced for me at this point. If anyone can offer some tips I'd appreciate it. Thanks in advance.

  • Can a 32-bit RHEL4 userland work with a 64-bit kernel?

    - by James
    Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

  • How do I execute a cmd in C#, then in the same window execute another command that follows?

    - by Ashh
    Hey Guys, Right what im trying to accomplish is a program that basically sets the active partition in 1 click, saving the effort time and skill of using cmd prompt etc. I have looked into the System.Management name space but couldn't work out how to use it :( So i have resorted to using CMD, i have got a module application written in C# and basically i want to run "DISKPART" which then starts the diskpart in the cmd window, then i want to ask it to "Select disk 0" followed by "select partition 1" finally followed by "active". Doing this in CMD yourself works fine but with an application its proved to be awkward :( What ive managed to get it to do is run DiskPart fine in one window with Process.Start, then get it to open a new window and run the next piece of code but because the new window hasnt ran the diskpart cmd it doesnt work :( Any suggestions? Thanks! Ash

I have tried rendering to both xlib and png surfaces, neither seems to work, that is nothing is drawn. Also, I have written the input surfaces to png files, and they appear to be working. Thanks.

The problem was with the printShardingStatus as it returned "too many chunks to print, use verbose if you want to print" mongos> db.printShardingStatus() --- Sharding Status --- sharding version: { "_id" : 1, "version" : 3 } shards: { "_id" : "shard0000", "host" : "localhost:10001" } { "_id" : "shard0001", "host" : "localhost:10002" } databases: { "_id" : "admin", "partitioned" : false, "primary" : "config" } { "_id" : "dbTest", "partitioned" : true, "primary" : "shard0000" } dbTest.things chunks: shard0001 12 shard0000 19 too many chunks to print, use verbose if you want to for ce print I found that for that particular command I can specify boolean parameter db.printShardingStatus(true) which wasn't shown using db.help().

  • starting subactivity for the second time causes java.lang.OutOfMemoryError

    - by Zacherl
    Hi there, I am developing a simple app which does a little bit of image-processing. It's divided in two activities; the main one with some display elements and the second one which is used to capture images off the phone's camera. To discribe my problem: I start the app, capture an image (by starting a new Intent with the subactivity) and all data is displayed correctly. If I capture another image after this, I run in an java.lang.OutOfMemoryError - bitmap size exceeds VM budget I dont store the captured bitmap, in the second activity I just extract some data from it and pass it to the main-activity; finishing (finish()) the sub-activity afterwards. I really dont know what I can do about it. Thanks in advance! greetings, Zacherl PS: It is my first approach to android, so I apologize for any stupid beginner error I did; if someone needs any further information, I would be happy to provide it.

  • What tool/framework to use for technical documentation?

    - by Pangea
    We develop products and frameworks to be used with in our organization. I am looking for programmer friendly documentation tools. I have researched on few options sometime back but couldn't decide which one to use. I am looking for suggestions from the people who already used these tools. docbook: springframework and hibernate use this format and this looks good. but I believe they have customized the default xslt/stylesheet. Can I copy and use their xslt and css (ofcourse with colors and images changed). Can I integrate the doc generation using maven? wiki: this is not friendly to the technical document writers and the documentation doesn't look professional. versioning is also not possible I believe word docs: this is what we use currently but it is hard to link and reuse common documents. DITA?

  • Test if element already has jQuery datepicker

    - by macca1
    I have a form with many input elements. Some are date fields with a jQuery UI datepicker alraedy attached: $("#someElement").mask("9?9/99/9999").datepicker({showOn: 'button', buttonText:'Click here to show calendar', duration: 'fast', buttonImageOnly: true, buttonImage: /images/calicon.gif' }); Then I have a key command bound to this function: function openCalendar() { var selection = document.activeElement; // { Need to test here if datepicker has already been initialized $(selection).datepicker("show"); // } } This works great for elements which already have the datepicker on them. However any other fields will throw a javascript error. I'm wondering the best way to test to see if datepicker has already been initialized on that field.

  • Are there Python ORMs out there that support multiple independent databases concurrently in use?

    - by sdt
    I'm writing an application in Python where I wish to use sqlite as the backing store for documents edited by the app, with documents generally living in memory, but being saved to disk-based databases when the application saves. Ideally I'd like to use something like an ORM to make access to the data from my Python application code simple. Unfortunately it seems like the majority of Python ORMs, including SQLAlchemy, SQLObject, Django, and Storm, associate the database connection (or engine or whatever) with the classes representing table data, rather than instances of those classes. This restricts these ORMs to working with a single database connection across all instances. Since I'd like to support having multiple documents open simultaneously, this isn't going to work for me. Are there any ORMs out there that support this usage model in Python? Bazaar seems to support this, but it's quite out of date, and at first glance appears to have some other shortcomings. Thanks for any suggestions!

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • alt-tab sort of web design

    - by sureshgl
    I am thinking of designing a web site having multiple related services. For every action of the user in a service there will be some computation going on in each of the other services. I want to display the service in action (chosen by the user) in the middle of the page in enlarged mode and rest of the services as small sized (shrunk) versions around the enlarged mode. The services which are shown in the shrunk version, should actually show what is happening in that service, at run time as if that was the chosen service. A close match to this sort of behavior I know is in Reliance BigTV, where all the small images of all the channels will be going on, and we can choose the one that we want to watch. After choosing that one image will become big and occupy the screen. Please, let me know if I can do some thing like this using css, html, ajax & php.

  • Help porting a bit of Prototype JavaScript to jQuery

    - by ewall
    I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!

  • Data truncation when retrieving data from MySQL database with prepared statements

    - by KSiimson
    I have a script that retrieves multiple products using prepared statements. Like putting loops into loops, I have prepared statements in prepared statements - so there is a prepared statement for retrieving all products, a prepared statement to retrieve all images for that product, a prepared statement to get all attributes for that products, and so on. This does not work with one MySQLi instance, so I use multiple MySQLi objects that are opened and closed when needed. It usually works fine, but sometimes, especially when displaying multiple products, some data is truncated. For example - MicoLoans becomes MicoLoa. There was an actual spelling mistake here - now when I changed MicoLoans to MicroLoans, the same page displayed MicroLoa... So the same number of characters was truncated from the end. It is sort of consistent where it appears - for example there can be descriptions for 8 products, and description of 1 product is heavily truncated. When I add 9th product, the short description is still truncated for that same product as before. Any ideas?

  • Storing uploaded content on a website

    - by Matt
    For the past 5 years, my typical solution for storing uploaded files (images, videos, documents, etc) was to throw everything into an "upload" folder and give it a unique name. I'm looking to refine my methods for storing uploaded content and I'm just wondering what other methods are used / preferred. I've considered storing each item in their own folder (folder name is the Id in the db) so I can preserve the uploaded file name. I've also considered uploading all media to a locked folder, then using a file handler, which you pass the Id of the file you want to download in the querystring, it would then read the file and send the bytes to the user. This is handy for checking access, and restricting bandwidth for users.

  • Sending BLOBs in a JSON service,... how?

    - by Marten Sytema
    Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

  • jQuery photo carousel (that looks like a real carousel)?

    - by kastru
    I am on the lookout for a jQuery photo carousel that can display 3 images at a time, and circle through x amount of photos (and when reaching the last, starting with the first photo again). I made a quick mock-up of what i am looking fore - see it here. So there is 3 photos vissible, the middle one beeing the 'main' one and a bit bigger than the previous and next (left and right). Upon clicking the next/previous arrows the next or previous photo slides into the middle and thereby becomes the main photo. Any ideas to where i can find such a jQuery plugin/script?
