• SQL Server 2005: When clicking "Add" database I keep getting 'verify that the path or file exists'

  - by Code Sherpa

  When I right click on "databases" in Sql Server 2005 Management Studio and then Attach... Add I get the following error: C:\Documents and Settings\Administrator\My Documents\SQL Server Management Studio\ Projects\Path\To\MDF\And\LDF\Files\ cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. The answer is easy - the MDF and LDF files where removed when Nant (by way of my dev machine) issued a drop command. But, after replacing the MDF and LDF files, I want to reattach the database but the above error keeps coming up when I select "Add". Also, I have already "unattached" the database in question and it no longer appears on the left under "databases". I have tried to replace a copy of the MDF and LDF files in the folder being referenced and that didn't work. Any ideas as to how to gracefully get rid of this error?

• Getting a query to index seek (rather than scan)

  - by PaulB

  Running the following query (SQL Server 2000) the execution plan shows that it used an index seek and Profiler shows it's doing 71 reads with a duration of 0. select top 1 id from table where name = '0010000546163' order by id desc Contrast that with the following with uses an index scan with 8500 reads and a duration of about a second. declare @p varchar(20) select @p = '0010000546163' select top 1 id from table where name = @p order by id desc Why is the execution plan different? Is there a way to change the second method to seek? thanks EDIT Table looks like CREATE TABLE [table] ( [Id] [int] IDENTITY (1, 1) NOT NULL , [Name] [varchar] (13) COLLATE Latin1_General_CI_AS NOT NULL) Id is primary clustered key There is a non-unique index on Name and a unique composite index on id/name There are other columns - left them out for brevity

• movedown method not saving new position - cakephp tree

  - by Ryan

  Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

• Expand <div> tag to bottom of page with CSS

  - by typoknig

  Hi all, I know this question gets asked a lot because I have looked at many "solutions" trying to get this to work for me. I can get it to work if I hack up the html but I want to use all CSS. All I want is a header with two columns below it, and I want these three items to fill the entire page/screen, and I want to do it with CSS and without frames or tables. The XAMPP user interface looks exactly how I want my page to look, but again, I do not want to use frames. I cannot get the two orangeish colored columns to extend to the bottom of the screen. I do have it so it looks like the right column extends to the bottom of the screen just by changing the body background color to the same color as the background color of the right column, but I would like both columns to extend to the bottom so I didn't have to do that. Here is what I have so far: HTML <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html dir="ltr" xmlns="http://www.w3.org/1999/xhtml"> <head> <title>MY SITE</title> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <link href="stylesheet.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="container"> <div id="masthead"> MY SITE</div> <div id="left_col"> Employee Management<br /> <a href="Employee%20Management.php">Add New Employee</a><br /> <a href="Employee%20Management.php">Edit Existing Employee</a><br /> <br/> Load Management<br /> <a href="Load%20Management.php">Log New Load</a><br /> <a href="Load%20Management.php">Edit Existing Load</a><br /> <br/> Report Management<br /> <a href="Report%20Management.php">Employee Report</a><br /> <a href="Report%20Management.php">Load Report</a></div> <div id="page_content"> <div id="page_content_heading">Welcome!</div> Lots of words</div> </div> </body> </html> CSS #masthead { background-color:#FFFFFF; font-family:Arial,Helvetica,sans-serif; font-size:xx-large; font-weight:bold; padding:30px; text-align:center; } #container { min-width: 600px; min-height: 100%; } #left_col { padding: 10px; background-color: #339933; float: left; font-family: Arial,Helvetica,sans-serif; font-size: large; font-weight: bold; width: 210px; } #page_content { background-color: #CCCCCC; margin-left: 230px; padding: 20px; } #page_content_heading { font-family:Arial,Helvetica,sans-serif; font-size:large; font-weight:bold; padding-bottom:10px; padding-top:10px; } a { color:#0000FF; font-family:Arial,Helvetica,sans-serif; font-size:medium; font-weight:normal; } a:hover { color:#FF0000; } html, body { height: 100%; padding: 0; margin: 0; background-color: #CCCCCC; }

• jQuery resize event for div children

  - by Frank Michael Kraft

  $("div.content-left > *, div.content-main > *" ).live('resize',function(){alert("Size changed")}); does not work, because the resize event only applies to window resizes. But in my case the divs change size late, because the content is loaded late by an ajax request - or by clicking a panel menu. I definatley need to avoid to register on all individual events of the children (ajax, click), because that can be very many different events and then it is not maintainable.

• How do I swap triangle icons when doing expanding/collapsing divs with Javascript/CSS

  - by SL

  I have a div that I want to toggle between displaying or not when a user clicks on a piece of text. I have a javascript function that toggles a div on or off. That works fine. What I don't know how to do is to have a triangle that points to the right or down depending on whether the div is open. My HTML looks like this: <a onclick="toggleDiv('myDiv');">Click here to expand or close div</a> <div id="myDiv" style="display:none"> ... </div> How do I add one of those triangles and have it point the right way, ideally with just HTML, Javascript, and CSS? The triangle would appear to the left of the "Click here..." string. Thanks.

• Delete files in C# that windows does not want me to delete?

  - by user315881

  At my company, we are writing a script to take care of simple tasks that we usually would do by hand. I am using c# to delete profiles in c:\documents and settings\, except a few. These will simply be left alone. The problem is that even with code that sets the files to normal and marks the admin user as an owner, they won't delete. They say that the quick launch folder has access denied. I am using a recursive permissions change method and I know that it works. Same thing with file attributes. Why won't it work? How do I fix this?

• How to achieve jQuery scrolling/overlay effect (video in description)

  - by waffl

  I have two columns. The left column contains text of dynamic lengths. The right column is of fixed height and will contain a set of images selected at random per page load. I am trying to create an effect where while the user scrolls, the Image 2 scrolls above Image 1. When it reaches the top, the Image 1 begins to scroll up until it disappears, then Image 3 comes in and repeats the process. As this is rather confusing, I made a short video describing the desired effect. Video - MP4 I have begun trying to get it working in this jsbin but am at a loss for when the user scrolls back down and also when more images are required. I am thinking my current path is not the right direction. I'm thinking that employing something like jQuery waypoints is more the direction I should be pursuing?

• Jquery - how to create a sophisticated sidebar that smoothly scrolls down with you

  - by Gal

  I probably couldn't depict it better in the title (and if it has a term let me know), but just to quell the obscurity, I was referring to something like this. After you wait for the page to load, see how when you scroll down, the social media left bar stays fixed, but then when you scroll just enough that it meets your upper side, it sticks to it as you scroll further. I wanted to implement something corny and pretentious like that, so does anybody know a tutorial or a method to get that done in jquery? (I can probably do it myself, if I'm not mistaken, just need some sense of direction from savvy jqueryists). Is there a way to know when and how much a user scrolls? Can it be done with id's like the # url appendix to jump to a specific element? Just some ideas...

• How to arrange labels in a flowlayout manner?

  - by Tim Büthe

  How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

• Apache mod_rewrite help with Wordpress

  - by protohominid

  I administer my wife's site, namelymarly.com. Up until last week, the root page of the blog was namelymarly.com/blog/. Last week I changed it in the WP settings to be namelymarly.com. WP created the new htaccess file, and I moved the index.php to the root directory (but left the WP folder where it was in the /blog/ directory), as instructed. Everything is working great except for one very important thing: When you type 'namelymarly.com/blog/' into a browser now, you get a 404 error. All other URLs, when they include the '/blog/somethinghere', will redirect properly to '/somethinghere.' It's only when there's nothing after '/blog/' that there's a problem. I tried adding this rule but it breaks the site: RewriteRule ^/blog(/|)$ / Any suggestions/help?

• Android Timer update UI between multiple tasks

  - by Rilcon42

  I have tried multiple ways to have a single persistent timer update the ui in multiple activities, and nothing seems to work. I have tried an AsyncTask, a Handler, and a CountDownTimer. The code below does not execute the first Log.i statement.... Is there a better way to start the timer (which must be called from another class) in Main (which is the only persistent class)? public static void MainLawTimer() { MainActivity.lawTimer = new CountDownTimer(MainActivity.timeLeft, 1000) { public void onTick(long millisUntilFinished) { Log.i("aaa","Timer running. Time left: "+MainActivity.timeLeft); MainActivity.timeLeft--; if(MainActivity.timeLeft<=0) { //do stuff } else { //call method in another class } }

• Mysql SELECT with an OR across 2 columns

  - by Haroldo

  I'm creating a 'similar items' link table. i have a 2 column table. both columns contains product ids. The table is showing that these items are similar. However ids in the left column are more valuable. Say i want to select similar items to product '125b'. i only want 3 similar items to 125b. If there are any instances of 125b in col1 I would prefer these to finding 125b in col2. so i need a select statement along the lines of SELECT * FROM similar_items WHERE col_1={$id} OR col_2={$id} ORDER BY column(?) LIMIT 3 i do not want to do 2 separate queries ( ie query 2 if count(query1) <3 )

• How do you combine a Move and Rotate effect in Flex 3?

  - by Impirator

  I realize you can make one of each effect, set the same target, and hit .play();, but this produces weird results (acknowledged by Adobe, fixed in Flex 4). I'm trying to have an object move from the top of the screen to the bottom while it rotates around it's own center. When called independently, both of these effects work perfectly. When called together, the object always rotates around the top left corner. I even tried putting them both inside a <Parallel> tag with no success. Has anyone come up with a workaround?

• Positioning child panels using FlowLayout

  - by extro

  I have two panels: main_panel child_panel The main_panel layout is set using: main_panel.setLayout(flowlayout) I then added child_panel to main_panel: main_panel.add(child_panel) The child_panel gets added to main_panel but its position is at the cross-section of horizontal midpoint and top vertical section of screen. I want child_panel to be at the top left corner, something I could have done by using child_panel.setlocation(a,b) method, if I have set the layout of main_panel as null. I have used FlowLayout here because I want components in the JPanel to keep adjusting with the size of JFrame. So can I add child_panel to main_panel at the exact location I want, even if I set the Layout of main_panel as not null?

• How to change the font size in table cells according to cells content ?

  - by misha-moroshko

  I have an HTML table which has incrementing numbers starting from 0 in its cells (left to right, up to bottom). I fixed in CSS the width and the height of the cells (40px width, 25px height, in my case). When the table becomes larger, the numbers inside it becomes large also (for example, the last number is 1266356). This causes the cells to be wider than I defined in the CSS, which expands the whole table accordingly. Instead, I would like the font of the numbers to be smaller to keep the width of the cell 40px. How can I accomplish this using CSS / Javascript / jQuery ?

• Algorithm for finding all paths in a NxN grid

  - by Periastron

  Imagine a robot sitting on the upper left hand corner of an NxN grid. The robot can only move in two directions: right and down. How many possible paths are there for the robot? I could find solution to this problem on Google, but I am not very clear with the explanations. I am trying to clearly understand the logic on how to solve this and implement in Java. Any help is appreciated. Update: This is an interview question. For now, I am trying to reach the bottom-right end and print the possible paths.

• Artificial Intelligence - What to put in, or leave out, and what can be inferred?

  - by D Scott

  I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.

• Setting an attribute in Jquery not working

  - by Probocop

  Hi, I have the following function which limits the amount of characters you can enter into a text area. What's meant to happen is, if the text length is higher than the text limit, set an attribute of disabled="disabled" on the submit button, but it isn't getting set, my function code is as follows: function limitChars(textid, limit, infodiv) { var text = $('#'+textid).val(); var textlength = text.length; if(textlength > limit) { $('#' + infodiv).html('You cannot write more then '+limit+' characters!'); $('input#submit').attr('disabled', 'disabled'); } else { $('#' + infodiv).html('You have '+ (limit - textlength) +' characters left.'); } } Any ideas?

• Shortest distance between points on a toroidally wrapped (x- and y- wrapping) map?

  - by mstksg

  I have a toroidal-ish Euclidean-ish map. That is the surface is a flat, Euclidean rectangle, but when a point moves to the right boundary, it will appear at the left boundary (at the same y value), given by x_new = x_old % width Basically, points are plotted based on: (x_new, y_new) = ( x_old % width, y_old % height) Think Pac Man -- walking off one edge of the screen will make you appear on the opposite edge. What's the best way to calculate the shortest distance between two points? The typical implementation suggests a large distance for points on opposite corners of the map, when in reality, the real wrapped distance is very close. The best way I can think of is calculating Classical Delta X and Wrapped Delta X, and Classical Delta Y and Wrapped Delta Y, and using the lower of each pair in the Sqrt(x^2+y^2) distance formula. But that would involve many checks, calculations, operations -- some that I feel might be unnecessary. Is there a better way?
