• Usability - How to edit favorites?

  - by Florian

  Hi, I'd like to get some opinions about about usability in the following case: Target group people from 30-50, low to middle internet affinity. App: I have a website with login. Visitors can save interesseting pages in their fav-box for fast access. Here the actual question: How to edit this favorites? Is it better to give the visitors direct access to drag/dropn and delete their favs or is it better to have an edit button so they have to activate the edit mode before? The fav-link would look like this | link text to click | icon-drag | icon-delete | thx for input TC

• Suggestions for Troubleshooting WIndows 7 lockups

  - by Craig L

  I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

• lock file so that it cannot be deleted

  - by JoeCool

  I'm working with two independent c/c++ applications on Windows where one of them constantly updates an image on disk (from a webcam) and the other reads that image for processing. This works fine and dandy 99.99% of the time, but every once in a while the reader app is in the middle of reading the image when the writer deletes it to refresh it with a new one. The obvious solution to me seems to be to have the reader put some sort of a lock on the file so that the writer can see that it can't delete it and thus spin-lock on it until it can delete and update. Is there anyway to do this? Or is there another simple design pattern I can use to get the same sort of constant image refreshing between two programs? Thanks, -Robert

• Any way of working with Eclipse WTP that does not mean redeploying the _WHOLE_ application when a J

  - by Thorbjørn Ravn Andersen

  I have migrated a Web Application from MyEclipse to Eclipse WTP, and I am now in the middle of the first major upgrade to the code base and web pages after the migration, and it is frankly driving me mad that saving a JSP page causes a redeployment of the WHOLE application, as it takes time and that my backend connection does not survive the serialization-deserialization of the session object (which is non-trivial to fix). In addition to that the JSP-editor is insanely slow so I frequently have to pause to let the editor catch up to be certain where my edits go in a small JSP using JavaServer Faces. Disabling validation did not help. The Eclipse Dynamic Web Project depends on several library eclipse projects so I cannot just tell e.g. Jetty to use the WebRoot folder, as several dependencies are then missing from the classpath. The question is: Is there a way of working - ANY way of working - with the Eclipse WTP system that does NOT imply redeploying everything every time any file is saved? I can use Tomcat 5.5 or Jetty 6 as servers.

• Output to console while preserving user input in ruby

  - by CaptnCraig

  I have a ruby script that is simultaneously and asynchronously receiving and displaying messages from a server, and allowing user input on the console. When a message is received, it is currently being written in the middle of what the user is typing. The input itself isn't garbled, but it looks horrible. Ideally, it would save the users current input, output the message, and then restore the input on the next line. I've done this in c by intercepting every key stroke, but all I remember is that it was a major hassle. I'm fairly new to ruby, so I'm not sure if there is a good way to do this, or how to do it. Example: User is typing >abcde, and message hello comes in, and user types fgh after. The console would now show: >abcdehellofgh and user can continue typing at the end. I would like it to show: hello >abcdefgh

• How do I show TextView's in LinearLayout that layed on other Layout?

  - by gelassen

  Good day. I have three layouts: first is the root, second and third lie in first. I try add TextView object in third layout and objects had been added in third layout (I saw it in debage mode) but this objects didn't showed on screen. May be someone know where is the problem? <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <Button android:id="@+id/addJokeButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/app_name" /> <EditText android:id="@+id/newJokeEditText" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> </LinearLayout> </LinearLayout> protected void initLayout() { setContentView(R.layout.advanced); LinearLayout linearLayout = (LinearLayout) getLayoutInflater().inflate( R.layout.advanced, null); m_vwJokeEditText = (EditText) findViewById(R.id.newJokeEditText); m_vwJokeButton = (Button) findViewById(R.id.addJokeButton); m_vwJokeLayout = (LinearLayout) linearLayout.getChildAt(1); } protected void addJoke(Joke joke) { m_arrJokeList.add(joke); LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); TextView textView = new TextView(this); setColor(textView); textView.setLayoutParams(lparams); textView.setText(joke.getJoke()); m_vwJokeLayout.addView(textView); }

• Multiple Service Address Configs in WCF Silverlight App

  - by CraigS

  My team is building our first significant Silverlight application, using a 3 layered architecture and WCF. We have developed about 10 separate WCF services in the middle layer so far, and this number is only going to grow. Generally, the presentation layer (ie. the Silverlight app) is pointing to the services as hosted on our dev server. However, there are times when I want it to access the services from localhost - ie. the developers machine. Is there an easy way to change where the presentation layer is looking for the services? Is there some way of easily switching between options here?

• Overtime culture slowly creeping in - How do I handle this?

  - by bobsmith123

  Our company was one of the very few companies that did not enforce overtime. As such, all my team members promptly worked 40-48 hours a week and everything was good. We hired a few new developers and one of them has positioned himself to be a team lead. He has started working overtime, sending emails in the middle of the night which has come somewhat as a shock for the laid back team. Obviously, the higher ups seem to love him for being the "bad guy" enforcing overtime. Before this goes out of control, what steps do I take to stop this from continuing. I would rather not bring this up with the bosses for the fear of being seen as a whining team member. I am not sure if I should reply to his email outside work hours and encourage him to enforce this culture on our team. Thoughts?

• Dell 620 display is too bright to use

  - by keith

  I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

• what are the possibilities of displaying items in a listbox.

  - by Selase

  Ive been trying to figure out for a long time now how to create an interface that can allows users to input several rows of data and passed those entries into an sql server database all at one shot. i could not get any better ideas so i came up with this.(see picture below.) so what i envisioned is that the user enters values in the textboxes and hits "add to list" button. the values are then populated in the list box below with the heading "exhibits lists" and when add exhibit button is pressed, all values from the list box are passed into the database. Well am left wondering again if it would be possible to tie this values from the texboxes to the list box and if id be able to pass them into the database. if it were possible then id please love to know how to go about it otherwise id be glad if you can recommend a better way for me to handle the situation otherwise id have to resolve to data entry one at a time.:(... Counting on you sublime advise. thanks. I believe there is some useful information from this website that can help solve my problem but i just cant make head and tail out of the article...it seems like am almost there and it skids off...can everyone please read and help me adapt it to my situation..thanks..post below http://www.codeproject.com/KB/aspnet/ExtendedGridView.aspx

• Which containers / graphics components to use in a simple Java Swing game?

  - by rize

  I'm creating a simple labyrinth game with Java + Swing. The game draws a randomized labyrinth on the screen, places a figure in the middle, and the player is then supposed to find the way out by moving the figure with arrow-keys. As for now, I'm using a plain background and drawing the walls of the labyrinth with Graphics.drawLine(). I have a custom picture of the figure in a .gif file, which I load as a BufferedImage object. However, I want the player to see only part of the labyrinth at a time, and the screen should follow the figure in the game, as the player moves around. I'm planning to do this by creating an Image object of the whole labyrinth when it is created, and then "cutting" a square around the current position of the figure and displaying this with Graphics.drawImage(). I'm new with Swing though, and I can't figure out how to draw the figure at different positions "above" the labyrinth without redrawing the whole thing. Which container/component should I use for the labyrinth and then for the figure to achieve this?

• Is ASP.Net Server Control, Postback Architecture failed in current Web 2.0 World.

  - by Lalit

  What i am looking around me is the drastically change in ASP.Net Architecture. More and more company are following the approach of JSON based wcf service in middle tier. Plain HTML based UI tier with JQuery/Ajax. No Postback at all, This contradicts the Default behaviour of Asp.Net Server Control/Code Behind Event handler/Postback. I am a Asp.Net Web Developer for around 4 years, and concerned about the future of ASP.Net. Is the Default Architecture of ASP.Net is Outdated at all? Does MVC or ASP.Net 4.0 Tries to solve the Issue?

• How to read a technical book to remember most of it?

  - by LikeToCode

  There are many technical books that become thinker and thicker and the pressure from the technical society is more and more to read them and remember many concepts described in them. But it's so hard to do it. I have only a few hour a week to read them and when I reach the middle of the book I forgot most of what I've read at the beginning, because lots of time passed. If I go back, I'll just re-read the same stuff over and over, never going past 50% of the book. So, even after I finished reading a thick tech book I forgot most of it. How do you remember all that stuff? I had a talk in my University on how to do it. They advised to use some cards with basic info so that you can remember the details when you look at it. Do you use such cards or do you have other ideas how to do it?

• Compaq nc4200 screen cutting out and keyboard lagging after dropping - could I repair this?

  - by Holly Gray

  I have a HP Compaq nc4200 laptop. I got it from a family member who no longer needed it, who got it from a sale of old office equipment, so it's at the very least third-hand, and somewhat battered. Today, I dropped it. It seemed unharmed at first, but the screen cuts out every few minutes (sometimes seconds), then fades back. Keyboard input also occasionally starts lagging, as does the mouse. It might be a coincidence, but, oddly, it seems as if, when the screen cuts out, it comes back sooner if I use the trackpad. Is this something that I could fix? What might be causing it?

• how to intercept processing when Session.IsNewSession is true

  - by Cen

  I have a small 4-page application for my customers to work through. They fill out information. If they let it sit too long, and the Session timeout out, I want to pop up a javascript alert that their session has expired, and that they need to start over. At that point, then redirected to the beginning page of the application. I'm getting some strange behavior. I'm stepping through code, forcing my Sessioni.IsNewSession to be true. At this point, I write out a call to Javascript to a Literal Control placed at the bottom of the . The javascript is called, and the redirection occurs. However, what is happening is.. I am pressing a button which is more or less a "Next Page" button and triggering this code. The next page is being displayed, and then the Alert and redirection occurs. The result I was expecting was to stay on the same page I received the "Timeout", with the alert to pop-up over it, then redirection. I'm checking for Session.IsNewSession in a BaseClass for these pages, overriding the OnInit event. Any ideas why I am getting this behavior? Thanks!

• jQuery tooltip: Trouble with remove()

  - by Rosarch

  I'm using a jQuery tooltip plugin. I have HTML like this: <li class="term ui-droppable"> <strong>Fall 2011</strong> <li class="course ui-draggable">Biological Statistics I<a class="remove-course-button" href="">[X]</a></li> <div class="term-meta-data"> <p class="total-credits too-few-credits">Total credits: 3</p> <p class="median-GPA low-GPA">Median Historical GPA: 2.00</p> </div> </li> I want to remove the .course element. So, I attach a click handler to the <a>: function _addDeleteButton(course, term) { var delete_button = $('<a href="" class="remove-course-button" title="Remove this course">[X]</a>'); course.append(delete_button); $(delete_button).click(function() { course.remove(); return false; }).tooltip(); } This all works fine, in terms of attaching the click handler. However, when course.remove() is called, Firebug reports an error in tooltip.js: Line 282 tsettings is null if ((!IE || !$.fn.bgiframe) && tsettings.fade) { What am I doing wrong? If the link has a tooltip attached, do I need to remove it specially? UPDATE: Removing .tooltip() solve the problem. I'd like to keep it in, but that makes me suspect that my use of .tooltip() is incorrect here.

• ASP.Net ListBox selections not working in Panel?

  - by larryq

  Hi everyone, I'm having trouble processing a listbox after selecting some items from it. In my markup, the listbox is contained within an asp:panel and is populated during page load in the codebehind. That part works fine. It's when I select various items and submit that I have trouble. My handler loops through the listbox items but doesn't see any as being selected. I'm not sure why. Here's the markup: <asp:Panel ID="panEdit" runat="server" Height="180px" Width="400px" CssClass="ModalWindow"> <table width="100%"> <asp:label runat = "server">Choose your items</asp:label> <tr> <td> <asp:ListBox ID="lstFundList" runat="server" SelectionMode="Multiple" OnLoad="lstFundList_LoadData"> </asp:ListBox> </td> </tr> </table> <asp:Button ID="btnUpdate" runat="server" Text="Update" OnClick="btnUpdate_OnClick"/> <asp:Button ID="btnCancel" runat="server" Text="Cancel" OnClientClick="$find('ModalPopupExtender1').hide(); return false;" /> </asp:Panel> In my btnUpdate_OnClick handler I can't see any listbox items that are marked as selected. I assume something strange is going on with respect to postback and the panel?

• FLEX: customized tag Cloud, how to compute positioning and distances

  - by Patrick

  hi, I want to build a tag cloud like this one in my Flex application. See image: http://dl.dropbox.com/u/72686/tagCloud.png At the moment I have the tags (that are mx.controls.LinkButtons) added at the same position and having different sizes according to values (stored in an ArrayComponent). In my visualization, the orange tags are supposed to be listed vertically in the middle. The gray tags should be at different distances (according to stored numeric values). I want to avoid overlapping and cluttering. How do you suggest to compute x and y of the gray tags taking care about: the distances from orange tags avoid overlapping between them thanks

• 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.

• Hiding monitor from windows, working with it from my app only [closed]

  - by Mikhail

  I need to use a monitor as a "private" device for my special application, I want to use it as a flashlight of a sort and draw special patterns on it in full screen. I don't want this monitor to be recognized by OS (Windows 7) as a monitor. I.e. user should not be able to move mouse to that monitor, or change its resolution, or run screensaver on it or whatever. But I want to be able to interact with it from my application. Monitor is plugged using an HDMI cable to a video card (most probably nVidia). What is the simplest way to do this? All solutions are appreciated, including purchasing additional adapters or simple video cards, or any other special devices.

• Mouseover triggered on absolute positioned div

  - by Tauren

  Objective Have a small magnifying glass icon that appears in the top right corner of a table cell when the table cell is hovered over. Mousing over the magnifying glass icon and clicking it will open a dialog window to show detailed information about the item in that particular table cell. I want to reuse the same icon for hundreds of table cells without recreating it each time. Partial Solution Have a single <span> that is absolutely positioned and hidden. When a _previewable table cell is hovered, the <span> is moved to the correct location and shown. This <span> is also moved in the DOM to be a child of the _previewable table cell. This enables a click handler attached to the <span> to find the _previewable parent, and get information from it's jquery data() object that is used to populate the contents of the dialog. Here is a very simplified version of my HTML: <body> <span id="options"> <a class="ui-state-default ui-corner-all"> <span class="ui-icon ui-icon-search"></span> Preview </a> </span> <table> <tr> <td class="_previewable"> <img scr="user_1.png"/> <span>Bob Smith</span> </td> </tr> </table> </body> And this CSS: #options { position: absolute; display: none; } With this jQuery code: var $options = $('#options'); $options.click(function() { $item = $(this).parents("._previewable"); // Show popup based on data in $item.data("id"); Layout.renderPopup($item.data("id"),$item.data("popup")); }); $('._previewable').live('mouseover mouseout',function(event) { if (event.type == 'mouseover') { var $target = $(this); var $parent = $target.offsetParent()[0]; var left = $parent.scrollLeft + $target.position().left + $target.outerWidth() - $options.outerWidth() + 1; var top = $parent.scrollTop + $target.position().top + 2; $options.appendTo($target); $options.css({ "left": left + "px", "top": top + "px" }).show(); } else { // On mouseout, $options continues to be a child of $(this) $options.hide(); } }); Problem This solution works perfectly until the contents of my table are reloaded or changed via AJAX. Because the <span> was moved from the <body> to be a child of the cell, it gets thrown out and replaced during the AJAX call. So my first thought is to move the <span> back to the body on mouseout of the table cell, like this: else { // On mouseout, $options is moved back to be a child of body $options.appendTo("body"); $options.hide(); } However, with this, the <span> disappears as soon as it is mouseover. The mouseout event seems to be called on _previewable when the mouse moves into the <span>, even though the <span> is a child of _previewable and fully displayed within the boundaries of the _previewable table cell. At this point, I've only tested this in Chrome. Questions Why would mouseout be called on _previewable, when the mouse is still within the boundaries of _previewable? Is it because the <span> is absolutely positioned? How can I make this work, without recreating the <span> and it's click handler on each AJAX table referesh?

• PHP - HTML Purifier - hello w<o>rld/world tutorial striptags

  - by JW

  I am just looking into using HTML Purifier to ensure that a user-inputed string (that represents the name of a person) is sanitized. I do not want to allow any html tags, script, markup etc - I just want the alpha, numeric and normal punctuation characters. The sheer number of options available for HTML Purifier is daunting and, as far as i can see, the docs do not seem to have a beggining/middle or end see: http://htmlpurifier.org/docs Is there a simple hello world tutorial online that shows how to sanitize a string removing all the bad stuff out of it. I am also considering just using strip tags: http://php.net/manual/en/function.strip-tags.php or PHP's in built data sanitizing http://us.php.net/manual/en/book.filter.php
