  • Magento Problem

    - by a1anm
    I am running a store on Magento. For some reason the "Recently Viewed", "Related Items" and "Featured Items" blocks have all disappeared from my site. They where definitely there yesterday so I'm not sure what's happened to them. Featured Products is an extension I use and show on the home page using: {{block type="featuredproducts/listing" template="inchoo/block_featured_products_main.phtml"}} Does anyone have any idea what the problem could be?

    - by Greg
    I'm trying to add a row to a table and have that row slide into view, however the slidedown function seems to be adding a display:block style to the table row which messes up the layout. Any ideas how to work around this? Here's the code: $.get('/some_url',{'val1':id}, function(data){ var row = $('#detailed_edit_row'); row.hide(); row.html(data); row.slideDown(1000); });

  • Make a final call to the Database when user leaves website (ASPX)?

    - by Jisaak
    I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?

  • How can I fix this touch event / draw loop "deadlock"?

    - by Josh
    Just want to start out by saying this seems like a great site, hope you guys can help! I'm trying to use the structure laid out in LunarLander to create a simple game in which the user can drag some bitmaps around on the screen (the actual game is more complex, but that's not important). I ripped out the irrelevant parts of LanderLander, and set up my own bitmap drawing, something like BoardThread (an inner class of BoardView): run() { while(mRun) { canvas = lockSurfaceHolder... syncronized(mSurfaceHolder) { /* drawStuff using member position fields in BoardView */ } unlockSurfaceHolder } } My drawStuff simply walks through some arrays and throws bitmaps onto the canvas. All that works fine. Then I wanted to start handling touch events so that when the user presses a bitmap, it is selected, when the user unpresses a bitmap, it is deselected, and if a bitmap is selected during a touch move event, the bitmap is dragged. I did this stuff by listening for touch events in the BoardView's parent, BoardActivity, and passing them down into the BoardView. Something like In BoardView handleTouchEvent(MotionEvent e) { synchronized(mSurfaceHolder) { /* Modify shared member fields in BoardView so BoardThread can render the bitmaps */ } } This ALSO works fine. I can drag my tiles around the screen no problem. However, every once in a while, when the app first starts up and I trigger my first touch event, the handleTouchEvent stops executing at the synchronized line (as viewed in DDMS). The drawing loop is active during this time (I can tell because a timer changes onscreen), and it usually takes several seconds or more before a bunch of touch events come through the pipeline and everything is fine again. This doesn't seem like deadlock to me, since the draw loop is constantly going in and out of its syncronized block. Shouldn't this allow the event handling thread to grab a lock on mSurfaceHolder? What's going on here? Anyone have suggestions for improving how I've structured this? Some other info. This "hang" only ever occurs on first touch event after activity start. This includes on orientation change after restoreState has been called. Also, I can remove EVERYTHING within the syncronized block in the event handler, and it will still get hung up at the syncronized call. Thanks!

  • Alter stored procedure if condition is met

    - by Matt
    I am looking to alter a stored procedure if a condition exists. I want to leave the stored procedure as is if the condition is not met, so drop/create is not really an option. Trying to put the contents of ALTER PROC inside an IF block is throwing up errors for me. Any thoughts?

  • try .. catch blocks - when to use

    - by Konrad
    I have always been of the belief that if a method can throw an exception then it is reckless not to protect this call with a meaningful try block. I just posted 'You should ALWAYS wrap calls that can throw in try, catch blocks.' to this question and was told that it was 'remarkably bad advice' - I'd like to understand why. Thanks!

  • Linking to a section of a site that is hidden by a hide/show JavaScript function

    - by hollyb
    I am using a bit of JavaScript to show/hide sections of a site when a tab is clicked. I'm trying to figure out if there is a way I can link back to the page and have a certain tab open based on that link. Here is the JS: var ids=new Array('section1','section2','section3','section4'); function switchid(id, el){ hideallids(); showdiv(id); var li = el.parentNode.parentNode.childNodes[0]; while (li) { if (!li.tagName || li.tagName.toLowerCase() != "li") li = li.nextSibling; // skip the text node if (li) { li.className = ""; li = li.nextSibling; } } el.parentNode.className = "active"; } function hideallids(){ //loop through the array and hide each element by id for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id document.getElementById(id).style.display = 'none'; } function showdiv(id) { //safe function to show an element with a specified id document.getElementById(id).style.display = 'block'; } And the HTML <ul> <li class="active"><a onclick="switchid('section1', this);return false;">One</a></li> <li><a onclick="switchid('section2', this);return false;">Two</a></li> <li><a onclick="switchid('section3', this);return false;">Three</a></li> <li><a onclick="switchid('section4', this);return false;">Four</a></li> </ul> <div id="section1" style="display:block;"> <div id="section2" style="display:none;"> <div id="section3" style="display:none;"> <div id="section4" style="display:none;"> I haven't been able to come up with a way to link back to a specific section. Is it even possible with this method? Thanks!

I have rerun compilemessages few times.
