    - by giglegi
    After I have the initial ASP.NET MVC 2 website and the default Membership provider up, how do I start adding features specific to an user? Like, say, we want to let users choose their favorite products and we want to remember these choices somehow or add a favorite color property to an user? Where should these customizations go and how should they be associated with the out-of-the-box membership system?

  • Twitter Bootstrap Navbar blocking svg viewBox

    - by user1167650
    I have a navbar fixed to the bottom and I have page that has a title and a giant svg (created by d3.js). I would like the svg to take up the entire screen (whatever is left over), but it always seems to have some part appear behind the bottom nav bar. I've tried: 1) using viewBox to auto-resize, setting the parent div and the svg to be block elements 2) adding padding-bottom to the body element But the svg still appears behind the navbar on wide screen monitors.

    - by RussP
    Oh gosh here a lot today - oops Folks, best way to do this: $j('.done').append('Your services have been updated'); (that bits done) but then remove the append after say 5 seconds so that if a person resubmits a form(allowed) the append does not continue adding the text? i.e updated once "Your services have been updated", twice would read "Your services have been updated Your services have been updated" but I would only want Your services have been updated to show once

  • Kernel error causing cpu to go into shutdown state

    - by EpsilonVector
    What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?

  • php zencart mod - having problems with attributes array

    - by user80151
    I inherited a zencart mod and can't figure out what's wrong. The customer selects a product and an attribute (model#). This is then sent to another form that they complete. When they submit the form, the product and the attribute should be included in the email sent. At this time, only the product is coming through. The attribute just says "array." The interesting part is, when I delete the line that prints the attribute, the products_options_names will print out. So I know that both the product and the products_options_names are working. The attribute is the only thing that is not working right. Here's what I believe to be the significant code. This is the page that has the form, so the attribute should already be passed to the form. //Begin Adding of New features //$productsimage = $product['productsImage']; $productsname = $product['productsName']; $attributes = $product['attributes']; $products_options_name = $value['products_options_name']; $arr_product_list[] = "<strong>Product Name:</strong> $productsname <br />"; $arr_product_list[] .= "<strong>Attributes:</strong> $attributes <br />"; $arr_product_list[] .= "<strong>Products Options Name:</strong> $products_options_name <br />"; $arr_product_list[] .= "---------------------------------------------------------------"; //End Adding of New features } // end foreach ($productArray as $product) ?> Above this, there is another section that has attributes: <?php echo $product['attributeHiddenField']; if (isset($product['attributes']) && is_array($product['attributes'])) { echo '<div class="cartAttribsList">'; echo '<ul>'; reset($product['attributes']); foreach ($product['attributes'] as $option => $value) { ?> Can anyone help me figure out what is wrong? I'm not sure if the problem is on this page or if the attribute isn't being passed to this page. TIA

    I'm putting together a Solution Architecture document for an enhancement we're adding to our site and it occurs to me that I've never formally illustrated a web service call before. Is there a convention for how web service calls are illustrated on your garden-variety network diagram? Can anyone point me to examples or share something on Create.ly (or similar service)?

  • Store children in database preserving information about their order

    - by GUZ
    I am designing database tables for a master-detail scenario. The specific requirement is that it is necessary to store information about the order of children. I see some possible solutions (like adding a column representing a position in the sequence, or a column with foreign key to the previous child) but I would like to know the best practices how to solve such problems. Best regards Lukasz Glaz

  • Should I merge .pbxproj files with git using merge=union?

    - by Ortwin Gentz
    I'm wondering whether the merge=union option in .gitattributes makes sense for .pbxproj files. The manpage states for this option: Run 3-way file level merge for text files, but take lines from both versions, instead of leaving conflict markers. This tends to leave the added lines in the resulting file in random order and the user should verify the result. Normally, this should be fine for the 90% case of adding files to the project. Does anybody have experience with this?

  • How Can I Get a TextPointer from a mouse click in a FlowDocument

    - by Bear
    I would like to get the word that a user has clicked on in a FlowDocument. I am currently adding an event handler to every Run in the document and iterating through the TextPointers in the Run that was clicked, calling GetCharacterRect() on each one and checking if the rectangle contains the point. However, when the click occurs near the end of a long Run this takes 10 seconds. Is there any more efficient method?
