  • Delphi: Application error logging in the field

    - by mawg
    Using Delphi 7, I wonder if there is a free component which will collect diagnostic information as my application runs at a remote site and will help me to debug error reports. Maybe it records each menu item selected, control clicked, text input, etc? Maybe it just dumps the stack on a crash. Maybe it does something else ... I don't mind adding code (e.g at the start and end of each procedure), as that might generate more useful info than a fully automatic system. I am not sure if the solution ought to "phone home" or if it is enough to produce a text file which can be emailed to me. Any suggestions?

  • Storing information for drop-down menus

    - by Mark
    Suppose you're building an HTML form and you want to have 2 or more drop-down menus, where after picking an option from the first, the 2nd menu is populated, and so forth. For example, choosing a country would bring up a list of provinces for that country, which would in turn list the cities. How would you store that sort of information in a database? Would you have a table Countries(id, name), Provinces(id, country_id, name), Cities(id, province_id, name) or would you have just one big denormalized table Entries(country, province, city)? (Why?)

  • How can I have multiple navigation paths with Django, like a simplifies wizard path and a full path?

    - by Zeta
    Lets say I have an application with a structure such as: System set date set name set something Other set death ray target calibrate and I want to have "back" and "next" buttons on a page. The catch is, if you're going in via the "wizard", I want the nav path to be something like "set name" - "set death ray target" - "set name". If you go via the Advanced options menu, I want to just iterate options... "set date" - "set name" - "set something" - "set death ray target" - calibrate. So far, I'm thinking I have to use different URIs, but that's that. Any ideia how this could be done? Thanks.

  • Touch Screen Product Catalog for Retail Store

    - by Patrick
    I am a UI/UX designer and I would like to create kiosk type of app that would be a product catalog (help/suggestor) for customers in a retail store using a touch screen monitor (and computer). Something as simple as this: http://www.youtube.com/watch?v=aoH0u6YTTK4 This is what I would like it to do: 1st Screen (Main Menu): Pick a type of category (For example: Dog, Cat, Small Animal) 2nd Screen pick a sub-category of a main category (For example: Puppy, Adult, Senior - DOG) 3rd Screen pick a sub-category of previous sub-category (For example: Food, Healthy, Toys) Then it will display a list of all products with a picture, small description, and price. Thats it. So the point of the kiosk is to help customers find certain products that match their pet criteria. (Dog Puppy Healthy Dog Food) I am wondering what is the best solution: RIA (Flex/Air or Silveright) or flash/action script. I am not sure what is the best technology to use for the following benefits: user-experience (smoothness of touch screen actions) and fast development.

  • Jquery Accordion and multiple slideshows

    - by Dipesh Parmar
    I've been using a lot of slideshows recently on my sites and one thing thats puzzled me is using more than one slideshow per page. I'm currently working on my own site, experimenting with Jquery Accordion. I've managed to adopt a very simple javascript slideshow, see below: http://dvpwebdesign.com/test/accordion/blank.html However i'm unable to either incorporate or use a different multiple slideshow plugin. I dont need slideshow navigation, so the The Cycle plugin works really well and i know you can use multiple slideshows. But if i either use Cycle alongside the current javascript slideshow, or only use the Cycle slideshow to avoid any possible conflict, the Accordion menu stops working. I just cant see what i am doing wrong, can anyone help?

  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • Strange margin-behaviour with Sifr spans in link (screens)

    - by knalstaaf
    I'm making a menu and it's supposed to look like picture nr 1 on this link. However, at this moment, it looks like picture nr 2. There's no logic in this behaviour, since all three elements have the same css-attributes. Moreover, let's change the word "Reiki" to "Psychotherapie" and see what happens... (picture nr 3) For some reason the word "Reiki" ignores certain attributes. This is not a problem when Sifr is turned off. I guess I'll need some extra CSS to solve this (messing with paddings, heights or margins on that specific element doesn't give any result. It just won't budge). Unless someone knows a more elegant solution?

  • I tried installing Ubuntu 10.04 and I got this message - any ideas on what to do?

    - by vette982
    No root file system defined. Please correct this from the partition menu. This message shows up when I first boot into Ubuntu after the installation. I installed it by mounting the ISO with Daemon Tools, and I just did the default Wubi installation. I keep reading everywhere that I need to choose my installation directory, but I don't get any option to do that. These are all the options I get for installation directory. I have a C and D partition on my drive, and I tried installing it on both and no luck either way. Any ideas?

  • Pull DIV from separate page and update DIV in current page

    - by brhea
    Hi everyone, I've got a simple one but haven't been able to find an example of a solution that fits exactly what I'm asking. Sorry in advance if this is a repeat. From my navigation menu, I want each link to reference a specific DIV in a separate page and then pull that DIV and replace the content in the current page. <ul> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> ..and so on </ul> Elsewhere in the page: <div id="displayContent">Content refreshes onClick. Previous content fades out, fresh content fades in.</div> Separate page (content.php): <div id="about">About content</div> <div id="contact">Contact content</div>

  • Proper programming procedure?

    - by Rob
    I am creating a scoring application which is dependent upon what a user selects at the beginning menu. Example: If a user clicks 18, I want it to base itself off 18 holes of golf. If a user clicks 9, I want it to base itself off 9 holes of golf. Is it better to create a separate class for the code for 9 holes, and then another for 18 holes and then launch whichever depending on what the user selects? Or should I keep everything in 1 file and use a global variable to define different parameters? Still very new to android programming (or programming in general) so not sure of the proper "etiquette" if you will... Also what would be the pro's and con's of doing it either way? (If any) Thanks in advance!

  • Reduce the file size of Excel

    - by Ram
    Hi, I'm working in an excel application and providing a menu to the user to add a new worksheet in that excel application (Excel Workbook). The worksheet will be added once the user clicks the "OK" button and I'm using a template to add this worksheet (The template has lot of formatting and formulas in it) Lets say the file size is 10 MB after adding a worksheet if the workbook is saved. Then I close the Excel application and reopen it and save the file then the file size is getting reduced to 8 MB. Can anybody let me know what could be the reason for the same? Thanks, Ram

  • What did they program this toy with?

    - by Trix
    A rather strange question: I'm often asking myself with what programming languages things were created. I recently found this toy mini computer I played with when I was 13 or so at home. (Note: It is not one of those toy "notebooks", it's really small and came as an extra with a magazine) "Features": Hadware: LCD with a small field of pixels where the games were going on, besides that some stats such as score, highscore etc. Sounds and horrible music when started A really small "keyboard" with a wire Software: At least 14 or so games, from Snake over Tetris and Breakdown to some abomination of a car racing game A calculator Game selecting menu An alarm clock Inside there is a really small circuit board, I don't want to open the thing up now, though. Can you imagine if the games and "Operating System" of this thing where actually programmed using a language? If yes, what language could it be? If not with a programming language, how else was it created?

  • Drupal, Views, Exposed filter: custom default selected tags

    - by Patrick
    hi I'm using Drupal, Views with a exposed filter (using taxonomy). My customer wants to set from back-end the default selected tags (in order to pre-filter the views content). In the exposed filter settings, there is functionality. However, it doesn't work properly: when I click on "Select None" link (I'm using better_exposed_filter module) I expect none of the tags are selected, instead, the default configuration (default selected tags) are selected, so actually it doesn't work anymore. I hope it is clear. So, I was wondering if I can prepare a custom menu in which my user can check/uncheck the default selected tags in the view. thanks

  • IE 8 Automatically Closing <header> tag

    - by djthoms
    Background I am currently working on the final QA of a responsive website and I'm having an issue with IE 8 and IE 7. My client deals with government contracting so their website needs to be compatible with IE 8 and IE 7. I am using Modernizr with html5shiv built in. I am loading Modernizr in the footer of a WordPress theme that was custom built for this project. I'm not missing a doctype or any other obvious code. I am using the following scripts, all of which are loaded in the footer of WordPress: jQuery 1.10.1 Modernizr 2.6.3 (click for config) respond.js 1.3.0 superfish jQuery Waypoints 2.0.3 jQuery Waypoints Sticky 2.0.3 The Situation I'm having an issue with IE 8 automatically closing a <header> tag.

  • How do I get the inner arrays length in a 2d array in C#?

    - by Phukab
    Lets say I create a jagged 2d array like so: public static char[,] phoneLetterMapping = { {'0'}, {'1'}, {'A', 'B', 'C'} }; Now, given the first index of the array, I would like to be able to get the length of the inner array. So, I would like to be able to do something like: phoneLetterMapping[2].length I can do that in Java. But the intellisense menu doesn't return the normal members of an array when I type in the first bracket of the [][] 2d array. So, how do I get the inner array lengths in my 2d array in C#?

    - by Digvijay Yadav

  • Is there a way to test my nonce validation fails when it should?

    - by MrsLannister
    I'm using nonce validation in a wordpress plugin. When I submit the form from the admin menu it processes correctly, so I believe the nonce validation is working. What I'm not sure is if the validation will fail when it is supposed to and I don't know what the best way to test this is. I tried putting the url for the php file in directly, but all it does it take me to a wordpress not found page. Is there some recommended way to test this? Here is my code. Again, the test passes when it is supposed to, I just don't know if it fails when it is supposed to. if ( !wp_verify_nonce( $ecbs_post_data['_wpnonce'], 'ecbs-edit-templates' ) ) { wp_die( __( 'You do not have permission to update this page.' ) ); }

  • Java Swing UI Changing Method

    - by vigilant
    I would like to use Swing to program a simple learning game. I am wondering what would be best way to switch between UI screens. For example, I would have a screen for the Main Menu, and then when the user presses a button on that screen, I would swap out the whole screen for a completely different one. Then, arbitrary screens can be swapped in at any moment, and all of their event handlers would be reactivated while the inactive screen's event handlers will be deactivated. What type of Swing component/control would I use for each of the 'screens'. Is this even doable?

  • Eclipse: The icons in "Display View" are all greyed out

    - by Mark Silberbauer
    The discussion here describes the "display view" in eclipse which allows one to to quickly evaluate java expressions. The thing is, when I open the display view the icons remain greyed out and I can't execute anything. The only icon that isn't is "clear console". The odd thing is, alot of the screenshots on the web show the same behaviour but the people posting about the feature don't mentioned it. There aren't any options in the context sensitive menu either. I'm trying it on a java project. I've tried it in the debug view and I get the same issue. I'll provide a screenshot once my hosting is sorted. I'm using eclipse 3.4.

But the select event is not firing at all. Neither is focus. What am I doing wrong?

In my computer, there is no aspnetdb.mdf under dir D:\Projects\MyTest\App_Data, and I have used aspnet_regsql to generate database successfully before I run the configuration tool. Why there is such error? How to fix it? thanks in advance, George

  • Easiest way to submit data via PHP?

    - by Abijah
    I'm new to PHP, and have spent 10 hours trying to figure this problem out. The goal is to take all data entered into this order form, and send it to my email via PHP. I have 2 questions: 1. I can get PHP to send data from a single menu item (example: Mexican Tortas), but how do I get PHP to send data from multiple items (example: Mexican Tortas, Fish Sandwich and Hamburger)? 2. How do I tell PHP to not send data from menu items that don't have the "How Many?" or "Customize It?" text fields filled out? If you could provide a super simple example (or a link to a learning resource) I would really appreciate it. Thank you, Abijah PHP <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "New Order"; $name_field = $_POST['name']; $phone_field = $_POST['phone']; $item = $_POST['item']; $quantity = $_POST['quantity']; $customize = $_POST['customize']; } $body = "Name: $name_field\nPhone: $phone_field\n\nItem: $item\nQuantity: $quantity\nCustomize: $customize"; echo "Data has been submitted to $to!"; mail($to, $subject, $body); ?> HTML <form action="neworder.php" method="POST"> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/mexicantortas.jpg"> <h1>Mexican Torta - $8.50</h1> <input name="item" type="hidden" value="Mexican Torta"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/fishsandwich.jpg"> <h1>Fish Sandwich - $8.50</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/hamburgers.jpg"> <h1>Hamburger w/ Fries - $7.00</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class="horizontal_form"> <div class="form"> <h2>Place Your Order Now: <font size="3"><font color="#037B41">Fill in the form below, and we'll call you when your food is ready to be picked up...</font></font></h2> <p class="name"> <input type="text" name="name" id="name" style="text-align:center;" onClick="this.value='';" value="Enter your name"/> </p> <p class="phone"> <input type="text" name="phone" id="phone" style="text-align:center;" onClick="this.value='';" value="Enter your phone #"/> </p> <p class="submit"> <input type="submit" value="Place Order" name="submit"/> </p> </div><!-- FORM --> </div><!-- HORIZONTAL_FORM --> </form>

  • Consuming a web service with the Netbeans Platform

    - by Dean
    I have an application that is written with the NetBeans Platform 5.5. I'm having trouble consuming a web service. If I create a Java SE application in NetBeans, I can add a web service reference without problem. Since my application is using the NetBeans Platform, many of the menu choices change. So, I cannot figure out how to add a reference to the web service. I've googled this topic a number of ways but haven't found any pages that deal with consuming a service through the platform. They all talk about consuming a service with a Java SE application. Changing the application from the Platform architecture is not an option.
