  • jQuery::Scrollable Div does not work

    I am trying to create a scrollable DIV using the following: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <title>Test</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <style type="text/css"> div.container { overflow:hidden; width:200px; height:200px; } div.content { position:relative; top:0; } </style> <script type="text/javascript"> $(function(){ $(".container a.up").bind("click", function(){ var topVal = $(this).parents(".container").find(".content").css("top"); $(this).parents(".container").find(".content").css("top", topVal-10); }); $(".container a.dn").bind("click", function(){ var topVal = $(this).parents(".container").find(".content").css("top"); $(this).parents(".container").find(".content").css("top", topVal+10); }); }); </script> </head> <body> <div class="container"> <p> <a href="#" class="up">Up</a> / <a href="#" class="dn">Down</a> </p> <div class="content"> <p>Hello World 1</p> <p>Hello World 2</p> <p>Hello World 3</p> <p>Hello World 4</p> <p>Hello World 5</p> <p>Hello World 6</p> <p>Hello World 7</p> <p>Hello World 8</p> <p>Hello World 9</p> <p>Hello World 10</p> <p>Hello World 10</p> <p>Hello World 11</p> <p>Hello World 12</p> <p>Hello World 13</p> <p>Hello World 14</p> <p>Hello World 15</p> <p>Hello World 16</p> <p>Hello World 17</p> <p>Hello World 18</p> <p>Hello World 19</p> <p>Hello World 20</p> <p>Hello World 21</p> <p>Hello World 22</p> <p>Hello World 23</p> <p>Hello World 24</p> <p>Hello World 25</p> <p>Hello World 26</p> <p>Hello World 27</p> </div> </div> </body> </html> I don't know where I am messing up, but it simply refuses to work.

  • Compiler issues on VC++ 2008 Express, Seemingly correct code throws errors.

    - by Anthony Clever
    Hi there, I've been trying to get back into coding for a while, so I figured I'd start with some simple SDL, now, without the file i/o, this compiles fine, but when I throw in the stdio code, it starts throwing errors. This I'm not sure about, I don't see any problem with the code itself, however, like I said, I might as well be a newbie, and figured I'd come here to get someone with a little more experience with this type of thing to look at it. I guess my question boils down to: "Why doesn't this compile under Microsoft's Visual C++ 2008 Express?" I've attached the error log at the bottom of the code snippet. Thanks in advance for any help. #include "SDL/SDL.h" #include "stdio.h" int main(int argc, char *argv[]) { FILE *stderr; FILE *stdout; stderr = fopen("stderr", "wb"); stdout = fopen("stdout", "wb"); SDL_Init(SDL_INIT_EVERYTHING); fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n"); SDL_Quit(); fprintf(stderr, "SDL QUIT.\n"); fclose(stderr); fclose(stdout); return 0; } /* 1>------ Build started: Project: opengl_crap, Configuration: Debug Win32 ------ 1>Compiling... 1>main.cpp 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2090: function returns array 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2528: '__iob_func' : pointer to reference is illegal 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2556: 'FILE ***__iob_func(void)' : overloaded function differs only by return type from 'FILE *__iob_func(void)' 1> c:\program files\microsoft visual studio 9.0\vc\include\stdio.h(132) : see declaration of '__iob_func' 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(7) : error C2090: function returns array 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(7) : error C2528: '__iob_func' : pointer to reference is illegal 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(9) : error C2440: '=' : cannot convert from 'FILE *' to 'FILE ***' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(10) : error C2440: '=' : cannot convert from 'FILE *' to 'FILE ***' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(13) : error C2664: 'fprintf' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(15) : error C2664: 'fprintf' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(17) : error C2664: 'fclose' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(18) : error C2664: 'fclose' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>Build log was saved at "file://c:\Documents and Settings\Owner\My Documents\Visual Studio 2008\Projects\opengl_crap\opengl_crap\Debug\BuildLog.htm" 1>opengl_crap - 11 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== */

    - by Shantanu Gupta
    I have a stored procedure that is performing some ddl dml operations. It retrieves a data after processing data from CTE and cross apply and other such complex things. Now this returns me a 4 tables which gets binded to various sources at frontend. Now I want to use one of the table to further processing so as to get more usefull information from it. eg. This table would be containing approx 2000 records at most of which i want to get records that belongs to lodging only.

  • iPhone: Repeating Rows in Each Section of Grouped UITableview

    - by Rank Beginner
    I'm trying to learn how to use the UITableView in conjunction with a SQLite back end. My issue is that I've gotten the table to populate with the records from the database, however I'm having a problem with the section titles. I am not able to figure out the proper set up for this, and I'm repeating all tasks under each section. The table looks like this. The groups field is where I'm trying to pull the section title from. TaskID groups TaskName sched lastCompleted nextCompleted success 1 Household laundry 3 03/19/2010 03/22/2010 y 1 Automotive Change oil 3 03/20/2010 03/23/2010 y In my viewDidLoad Method, I create an array from each column in the table like below. //Create and initialize arrays from table columns //______________________________________________________________________________________ ids =[[NSMutableArray alloc] init]; tasks =[[NSMutableArray alloc] init]; sched =[[NSMutableArray alloc] init]; lastComplete =[[NSMutableArray alloc] init]; nextComplete =[[NSMutableArray alloc] init]; weight =[[NSMutableArray alloc] init]; success =[[NSMutableArray alloc] init]; group =[[NSMutableArray alloc] init]; // Bind them to the data //______________________________________________________________________________________ NSString *query = [NSString stringWithFormat:@"SELECT * FROM Tasks ORDER BY nextComplete "]; sqlite3_stmt *statement; if (sqlite3_prepare_v2( database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { [ids addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 0)]]; [group addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 1)]]; [tasks addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 2)]]; [sched addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 3)]]; [lastComplete addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 4)]]; [nextComplete addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 5)]]; [success addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 6)]]; [weight addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 7)]]; } sqlite3_finalize(statement); } In the table method:cellForRowAtIndexPath, I create controls on the fly and set their text properties to objects in the array. Below is a sample, I can provide more but am already working on a book here... :) /create the task label NSString *tmpMessage; tmpMessage = [NSString stringWithFormat:@"%@ every %@ days, for %@ points",[tasks objectAtIndex:indexPath.row],[sched objectAtIndex:indexPath.row],[weight objectAtIndex:indexPath.row]]; CGRect schedLabelRect = CGRectMake(0, 0, 250, 15); UILabel *lblSched = [[UILabel alloc] initWithFrame:schedLabelRect]; lblSched.textAlignment = UITextAlignmentLeft; lblSched.text = tmpMessage; lblSched.font = [UIFont boldSystemFontOfSize:10]; [cell.contentView addSubview: lblSched]; [lblSched release]; My numberOfSectionsInTableView method looks like this // Figure out how many sections there are by a distinct count of the groups field // The groups are entered by user when creating tasks //______________________________________________________________________________________ NSString *groupquery = [NSString stringWithFormat:@"SELECT COUNT(DISTINCT groups) as Sum FROM Tasks"]; int sum; sqlite3_stmt *statement; if (sqlite3_prepare_v2( database, [groupquery UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { sum = sqlite3_column_int(statement, 0); } sqlite3_finalize(statement); } if (sum=0) { return 1; } return 2; } I know I'm going wrong here but this is all that's in my numberOfRowsInSection method return [ids count];

  • Trouble Percent-Encoding Spaces in Java

    - by behrk2
    Hi Everyone, I am using the URLUTF8Encoder.java class from W3C (www.w3.org/International/URLUTF8Encoder.java). Currently, it will encode any blank spaces ' ' into plus signs '+'. I am having difficulty modifying the code to percent-encode the blank space into '%20'. Unfortunately, I am not too familiar with hex. Can anyone help me out? I need to modify this snippet... else if (ch == ' ') { // space sbuf.append('+'); in the following code: final static String[] hex = { "%00", "%01", "%02", "%03", "%04", "%05", "%06", "%07", "%08", "%09", "%0A", "%0B", "%0C", "%0D", "%0E", "%0F", "%10", "%11", "%12", "%13", "%14", "%15", "%16", "%17", "%18", "%19", "%1A", "%1B", "%1C", "%1D", "%1E", "%1F", "%20", "%21", "%22", "%23", "%24", "%25", "%26", "%27", "%28", "%29", "%2A", "%2B", "%2C", "%2D", "%2E", "%2F", "%30", "%31", "%32", "%33", "%34", "%35", "%36", "%37", "%38", "%39", "%3A", "%3B", "%3C", "%3D", "%3E", "%3F", "%40", "%41", "%42", "%43", "%44", "%45", "%46", "%47", "%48", "%49", "%4A", "%4B", "%4C", "%4D", "%4E", "%4F", "%50", "%51", "%52", "%53", "%54", "%55", "%56", "%57", "%58", "%59", "%5A", "%5B", "%5C", "%5D", "%5E", "%5F", "%60", "%61", "%62", "%63", "%64", "%65", "%66", "%67", "%68", "%69", "%6A", "%6B", "%6C", "%6D", "%6E", "%6F", "%70", "%71", "%72", "%73", "%74", "%75", "%76", "%77", "%78", "%79", "%7A", "%7B", "%7C", "%7D", "%7E", "%7F", "%80", "%81", "%82", "%83", "%84", "%85", "%86", "%87", "%88", "%89", "%8A", "%8B", "%8C", "%8D", "%8E", "%8F", "%90", "%91", "%92", "%93", "%94", "%95", "%96", "%97", "%98", "%99", "%9A", "%9B", "%9C", "%9D", "%9E", "%9F", "%A0", "%A1", "%A2", "%A3", "%A4", "%A5", "%A6", "%A7", "%A8", "%A9", "%AA", "%AB", "%AC", "%AD", "%AE", "%AF", "%B0", "%B1", "%B2", "%B3", "%B4", "%B5", "%B6", "%B7", "%B8", "%B9", "%BA", "%BB", "%BC", "%BD", "%BE", "%BF", "%C0", "%C1", "%C2", "%C3", "%C4", "%C5", "%C6", "%C7", "%C8", "%C9", "%CA", "%CB", "%CC", "%CD", "%CE", "%CF", "%D0", "%D1", "%D2", "%D3", "%D4", "%D5", "%D6", "%D7", "%D8", "%D9", "%DA", "%DB", "%DC", "%DD", "%DE", "%DF", "%E0", "%E1", "%E2", "%E3", "%E4", "%E5", "%E6", "%E7", "%E8", "%E9", "%EA", "%EB", "%EC", "%ED", "%EE", "%EF", "%F0", "%F1", "%F2", "%F3", "%F4", "%F5", "%F6", "%F7", "%F8", "%F9", "%FA", "%FB", "%FC", "%FD", "%FE", "%FF" }; public static String encode(String s) { StringBuffer sbuf = new StringBuffer(); int len = s.length(); for (int i = 0; i < len; i++) { int ch = s.charAt(i); if ('A' <= ch && ch <= 'Z') { // 'A'..'Z' sbuf.append((char) ch); } else if ('a' <= ch && ch <= 'z') { // 'a'..'z' sbuf.append((char) ch); } else if ('0' <= ch && ch <= '9') { // '0'..'9' sbuf.append((char) ch); } else if (ch == ' ') { // space sbuf.append('+'); } else if (ch == '-' || ch == '_' // unreserved || ch == '.' || ch == '!' || ch == '~' || ch == '*' || ch == '\'' || ch == '(' || ch == ')') { sbuf.append((char) ch); } else if (ch <= 0x007f) { // other ASCII sbuf.append(hex[ch]); } else if (ch <= 0x07FF) { // non-ASCII <= 0x7FF sbuf.append(hex[0xc0 | (ch >> 6)]); sbuf.append(hex[0x80 | (ch & 0x3F)]); } else { // 0x7FF < ch <= 0xFFFF sbuf.append(hex[0xe0 | (ch >> 12)]); sbuf.append(hex[0x80 | ((ch >> 6) & 0x3F)]); sbuf.append(hex[0x80 | (ch & 0x3F)]); } } return sbuf.toString(); } Thanks!

  • Select number of rows for each group where two column values makes one group

    - by Fábio Antunes
    I have a two select statements joined by UNION ALL. In the first statement a where clause gathers only rows that have been shown previously to the user. The second statement gathers all rows that haven't been shown to the user, therefore I end up with the viewed results first and non-viewed results after. Of course this could simply be achieved with the same select statement using a simple ORDER BY, however the reason for two separate selects is simple after you realize what I hope to accomplish. Consider the following structure and data. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 1 | 1 | 10 | true | .... | | 2 | 10 | 1 | true | .... | | 3 | 1 | 10 | true | .... | | 4 | 6 | 8 | true | .... | | 5 | 1 | 10 | true | .... | | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | | 13 | 10 | 1 | false | .... | | 14 | 1 | 10 | false | .... | | 15 | 6 | 8 | false | .... | | 16 | 10 | 1 | false | .... | | 17 | 8 | 6 | false | .... | | 18 | 3 | 2 | false | .... | +----+------+-----+--------+------+ Basically I wish all non viewed rows to be selected by the statement, that is accomplished by checking weather the viewed column is true or false, pretty simple and straightforward, nothing to worry here. However when it comes to the rows already viewed, meaning the column viewed is TRUE, for those records I only want 3 rows to be returned for each group. The appropriate result in this instance should be the 3 most recent rows of each group. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | +----+------+-----+--------+------+ As you see from the ideal result set we have three groups. Therefore the desired query for the viewed results should show a maximum of 3 rows for each grouping it finds. In this case these groupings were 10 with 1 and 8 with 6, both which had three rows to be shown, while the other group 2 with 3 only had one row to be shown. Please note that where from = x and to = y, makes the same grouping as if it was from = y and to = x. Therefore considering the first grouping (10 with 1), from = 10 and to = 1 is the same group if it was from = 1 and to = 10. However there are plenty of groups in the whole table that I only wish the 3 most recent of each to be returned in the select statement, and thats my problem, I not sure how that can be accomplished in the most efficient way possible considering the table will have hundreds if not thousands of records at some point. Thanks for your help. Note: The columns id, from, to and viewed are indexed, that should help with performance. PS: I'm unsure on how to name this question exactly, if you have a better idea, be my guest and edit the title.

    Hello, I want to modify this code which works pretty good but (or I don't know because I'm new with php) I can't limit the number of li's displayed for the main elements in the menu. The actual code will echo all elements it finds, I want to limit the times <li><a href='{$sLink}' {$sOnclick} target='_parent'>{$sPictureRep}{$sText}</a> this line is echoed.. let's say to echo just the first 15 elements + a "MORE" button under which to display the rest of the elements as sub-menus.. (this is a 2 level horizontal menu). Can someone please help me? I really tried a lot but I'm not an expert in PHP.. Thanks! <?php require_once( '../../../inc/header.inc.php' ); require_once( DIRECTORY_PATH_INC . 'membership_levels.inc.php' ); require_once( DIRECTORY_PATH_ROOT . "templates/tmpl_{$tmpl}/scripts/TemplMenu.php" ); class SimpleMenu extends TemplMenu { function getCode() { $this->iElementsCntInLine = 100; $this->getMenuInfo(); $this->genTopItems(); return $this->sCode; } function genTopItem($sText, $sLink, $sTarget, $sOnclick, $bActive, $iItemID, $isBold = false, $sPicture = '') { $sActiveStyle = ($bActive) ? ' id="tm_active"' : ''; if (!$bActive) { $sAlt= $sOnclick ? ( ' alt="' . $sOnclick . '"' ) : ''; $sTarget = $sTarget ? ( ' target="_parent"' ) : ''; } $sLink = (strpos($sLink, 'http://') === false && !strlen($sOnclick)) ? $this->sSiteUrl . $sLink : $sLink; $sSubMenu = $this->getAllSubMenus($iItemID); $sImgTabStyle = $sPictureRep = ''; if ($isBold && $sPicture != '') { $sPicturePath = getTemplateIcon($sPicture); $sPictureRep = "<img src='{$sPicturePath}' style='vertical-align:middle;width:16px;height:16px;' />"; $sText = '&nbsp;'; $sImgTabStyle = 'style="width:38px;"'; } $sMainSubs = ($sSubMenu=='') ?

  • Why does File::Slurp return a scalar when it should return a list?

    - by BrianH
    I am new to the File::Slurp module, and on my first test with it, it was not giving the results I was expecting. It took me a while to figure it out, so now I am interested in why I was seeing this certain behavior. My call to File::Slurp looked like this: my @array = read_file( $file ) || die "Cannot read $file\n"; I included the "die" part because I am used to doing that when opening files. My @array would always end up with the entire contents of the file in the first element of the array. Finally I took out the "|| die" section, and it started working as I expected. Here is an example to illustrate: perl -de0 Loading DB routines from perl5db.pl version 1.22 Editor support available. Enter h or `h h' for help, or `man perldebug' for more help. main::(-e:1): 0 DB<1> use File::Slurp DB<2> $file = '/usr/java6_64/copyright' DB<3> x @array1 = read_file( $file ) 0 'Licensed material - Property of IBM.' 1 'IBM(R) SDK, Java(TM) Technology Edition, Version 6' 2 'IBM(R) Runtime Environment, Java(TM) Technology Edition, Version 6' 3 '' 4 'Copyright Sun Microsystems Inc, 1992, 2008.

DB<4> x @array2 = read_file( $file ) || die "Cannot read $file\n"; 0 'Licensed material - Property of IBM.

I have a feeling this might be more of a Perl precedence question instead of a File::Slurp question. I looked in the File::Slurp module and it looks like it is set to croak if there is a problem, so I guess the proper way to do it is to allow File::Slurp to croak for you. Now I'm just curious why I was seeing these differences.

  • Seemingly simple skinning problem in Flex4; style gives disco effect

    - by Cheradenine
    I'm doing something wrong, but I can't figure out what. Simple project in flex4, whereby I create a skinned combobox (fragments at end). If I turn on the 3 skin references (over-skin, up-skin, down-skin), the combobox appears to simply stop working. If I remove the up-skin, hovering over the combo produces a flickering effect, where it appears to apply the style, then remove it immediately. I get the same thing with a button instead of a combo. I'm sure it's something really simple, but it's evading me. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" xmlns:containers="flexlib.containers.*"> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> <fx:Style> @namespace s "library://ns.adobe.com/flex/spark"; @namespace mx "library://ns.adobe.com/flex/mx"; #myCombo { over-skin: ClassReference("nmx.MyComboSkin"); up-skin: ClassReference("nmx.MyComboSkin"); down-skin: ClassReference("nmx.MyComboSkin"); } </fx:Style> <fx:Script> <![CDATA[ [Bindable] public var items:Array = ["A","B","C"]; ]]> </fx:Script> <mx:Canvas backgroundColor="#ff0000" width="726" height="165" x="20" y="41"> <mx:ComboBox id="myCombo" x="10" y="10" prompt="Hospital" dataProvider="{items}"> </mx:ComboBox> </mx:Canvas> </s:Application> Skin Definition: package nmx { import flash.display.GradientType; import flash.display.Graphics; import mx.skins.Border; import mx.skins.ProgrammaticSkin; import mx.skins.halo.ComboBoxArrowSkin; import mx.skins.halo.HaloColors; import mx.utils.ColorUtil; public class MyComboSkin extends ProgrammaticSkin { public function MyComboSkin() { super(); } override protected function updateDisplayList(w:Number, h:Number):void { trace(name); super.updateDisplayList(w, h); var arrowColor:int = 0xffffff; var g:Graphics = graphics; g.clear(); // Draw the border and fill. switch (name) { case "upSkin": case "editableUpSkin": { g.moveTo(0,0); g.lineStyle(1,arrowColor); g.lineTo(w-1,0); g.lineTo(w-1,h-1); g.lineTo(0,h-1); g.lineTo(0,0); } break; case "overSkin": case "editableOverSkin": case "downSkin": case "editableDownSkin": { // border /*drawRoundRect( 0, 0, w, h, cr, [ themeColor, themeColor ], 1); */ g.moveTo(0,0); g.lineStyle(1,arrowColor); g.lineTo(w-1,0); g.lineTo(w-1,h-1); g.lineTo(0,h-1); g.lineTo(0,0); // Draw the triangle. g.beginFill(arrowColor); g.moveTo(w - 11.5, h / 2 + 3); g.lineTo(w - 15, h / 2 - 2); g.lineTo(w - 8, h / 2 - 2); g.lineTo(w - 11.5, h / 2 + 3); g.endFill(); } break; case "disabledSkin": case "editableDisabledSkin": { break; } } } } }

  • Android Augmented Reality

    - by Azooz Totti
    I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ?

  • I don't understand how work call_once

  • How color attributes work in VBO?

    - by Jayesh
    I am coding to OpenGL ES 2.0 (Webgl). I am using VBOs to draw primitives. I have vertex array, color array and array of indices. I have looked at sample codes, books and tutorial, but one thing I don't get - if color is defined per vertex how does it affect the polygonal surfaces adjacent to those vertices? (I am a newbie to OpenGL(ES)) I will explain with an example. I have a cube to draw. From what I read in OpenGLES book, the color is defined as an vertex attribute. In that case, if I want to draw 6 faces of the cube with 6 different colors how should I define the colors. The source of my confusion is: each vertex is common to 3 faces, then how will it help defining a color per vertex? (Or should the color be defined per index?). The fact that we need to subdivide these faces into triangles, makes it harder for me to understand how this relationship works. The same confusion goes for edges. Instead of drawing triangles, let's say I want to draw edges using LINES primitives. Each edge of different color. How am I supposed to define color attributes in that case? I have seen few working examples. Specifically this tutorial: http://learningwebgl.com/blog/?p=370 I see how color array is defined in the above example to draw a cube with 6 different colored faces, but I don't understand why is defined that way. (Why is each color copied 4 times into unpackedColors for instance?) Can someone explain how color attributes work in VBO? [The link above seems inaccessible, so I will post the relevant code here] cubeVertexPositionBuffer = gl.createBuffer(); gl.bindBuffer(gl.ARRAY_BUFFER, cubeVertexPositionBuffer); vertices = [ // Front face -1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0, -1.0, 1.0, 1.0, // Back face -1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0, 1.0, -1.0, -1.0, // Top face -1.0, 1.0, -1.0, -1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, -1.0, // Bottom face -1.0, -1.0, -1.0, 1.0, -1.0, -1.0, 1.0, -1.0, 1.0, -1.0, -1.0, 1.0, // Right face 1.0, -1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0, -1.0, 1.0, // Left face -1.0, -1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0, 1.0, -1.0, ]; gl.bufferData(gl.ARRAY_BUFFER, new WebGLFloatArray(vertices), gl.STATIC_DRAW); cubeVertexPositionBuffer.itemSize = 3; cubeVertexPositionBuffer.numItems = 24; cubeVertexColorBuffer = gl.createBuffer(); gl.bindBuffer(gl.ARRAY_BUFFER, cubeVertexColorBuffer); var colors = [ [1.0, 0.0, 0.0, 1.0], // Front face [1.0, 1.0, 0.0, 1.0], // Back face [0.0, 1.0, 0.0, 1.0], // Top face [1.0, 0.5, 0.5, 1.0], // Bottom face [1.0, 0.0, 1.0, 1.0], // Right face [0.0, 0.0, 1.0, 1.0], // Left face ]; var unpackedColors = [] for (var i in colors) { var color = colors[i]; for (var j=0; j < 4; j++) { unpackedColors = unpackedColors.concat(color); } } gl.bufferData(gl.ARRAY_BUFFER, new WebGLFloatArray(unpackedColors), gl.STATIC_DRAW); cubeVertexColorBuffer.itemSize = 4; cubeVertexColorBuffer.numItems = 24; cubeVertexIndexBuffer = gl.createBuffer(); gl.bindBuffer(gl.ELEMENT_ARRAY_BUFFER, cubeVertexIndexBuffer); var cubeVertexIndices = [ 0, 1, 2, 0, 2, 3, // Front face 4, 5, 6, 4, 6, 7, // Back face 8, 9, 10, 8, 10, 11, // Top face 12, 13, 14, 12, 14, 15, // Bottom face 16, 17, 18, 16, 18, 19, // Right face 20, 21, 22, 20, 22, 23 // Left face ] gl.bufferData(gl.ELEMENT_ARRAY_BUFFER, new WebGLUnsignedShortArray(cubeVertexIndices), gl.STATIC_DRAW); cubeVertexIndexBuffer.itemSize = 1; cubeVertexIndexBuffer.numItems = 36;

  • Plotting points so that they do not overlap if they have the same co-ordinates

    - by betamax
    Hi everyone, I have a function that takes longitude and latitude and converts it to x and y to be plotted. The conversion to X and Y is working fine and that is not what I have the problem with. I want to ensure that two points are not plotted in the same place. In one set of results there are about 30 on top of each other (because they have the same latitude and longitude), this number could be a lot larger. At the moment I am trying to achieve this by moving points to the left, right, top or bottom of the point to make a square. Once a square made up of points has been drawn, then moving to the next row on and drawing another square of points around the previous square. The code is Javascript but it is very generic so I guess it's slightly irrelevant. My code is as follows: var prevLong, prevLat, rand = 1, line = 1, spread = 8, i = 0; function plot_points(long, lat){ // CODE HERE TO CONVERT long and lat into x and y // System to not overlap the points if((prevLat == lat) && (prevLong == long)) { if(rand==1) { x += spread*line; } else if(rand==2) { x -= spread*line; } else if(rand==3) { y += spread*line; } else if(rand==4) { y -= spread*line; } else if(rand==5) { x += spread*line; y += spread*line; } else if(rand==6) { x -= spread*line; y -= spread*line; } else if(rand==7) { x += spread*line; y -= spread*line; } else if(rand==8) { x -= spread*line; y += spread*line; // x = double } else if(rand==9) { x += spread*line; y += spread; } else if(rand==10) { x += spread; y += spread*line; } else if(rand==11) { x -= spread*line; y -= spread; } else if(rand==12) { x -= spread; y -= spread*line; } else if(rand==13) { x += spread*line; y -= spread; } else if(rand==14) { x += spread; y -= spread*line; } else if(rand==15) { x += spread*line; y -= spread; } else if(rand==16) { x += spread; y -= spread*line; } else if(rand==17) { x -= spread*line; y += spread; } else if(rand==18) { x -= spread; y += spread*line; } else if(rand==19) { x -= spread*line; y += spread; } else if(rand==20) { x -= spread; y += spread*line; } if(rand == 20) {rand = 1; line++; } else { rand++; } i++ } else { line = 1; i = 0; } prevLat = latitude; prevLong = longitude; return [x,y]; } This is the output: It isn't working correctly and I don't even know if I am approaching the problem in a correct way at all. Has anyone had to do this before? What method would you suggest?

  • Database connection timeout

  • SQL Server 2005 Blocking Problem (ASYNC_NETWORK_IO)

    - by ivankolo
    I am responsible for a third-party application (no access to source) running on IIS and SQL Server 2005 (500 concurrent users, 1TB data, 8 IIS servers). We have recently started to see significant blocking on the database (after months of running this application in production with no problems). This occurs at random intervals during the day, approximately every 30 minutes, and affects between 20 and 100 sessions each time. All of the sessions eventually hit the application time out and the sessions abort. The problem disappears and then gradually re-emerges. The SPID responsible for the blocking always has the following features: WAIT TYPE = ASYNC_NETWORK_IO The SQL being run is “(@claimid varchar(15))SELECT claimid, enrollid, status, orgclaimid, resubclaimid, primaryclaimid FROM claim WHERE primaryclaimid = @claimid AND primaryclaimid < claimid)”. This is relatively innocuous SQL that should only return one or two records, not a large dataset. NO OTHER SQL statements have been implicated in the blocking, only this SQL statement. This is parameterized SQL for which an execution plan is cached in sys.dm_exec_cached_plans. This SPID has an object-level S lock on the claim table, so all UPDATEs/INSERTs to the claim table are also blocked. HOST ID varies. Different web servers are responsible for the blocking sessions. E.g., sometimes we trace back to web server 1, sometimes web server 2. When we trace back to the web server implicated in the blocking, we see the following: There is always some sort of application related error in the Event Log on the web server, linked to the Host ID and Host Process ID from the SQL Session. The error messages vary, usually some sort of SystemOutofMemory. (These error messages seem to be similar to error messages that we have seen in the past without such dramatic consequences. We think was happening before, but didn’t lead to blocking. Why now?) No known problems with the network adapters on either the web servers or the SQL server. (In any event the record set returned by the offending query would be small.) Things ruled out: Indexes are regularly defragmented. Statistics regularly updated. Increased sample size of statistics on claim.primaryclaimid. Forced recompilation of the cached execution plan. Created a compound index with primaryclaimid, claimid. No networking problems. No known issues on the web server. No changes to application software on web servers. We hypothesize that the chain of events goes something like this: Web server process submits SQL above. SQL server executes the SQL, during which it acquires a lock on the claim table. Web server process gets an error and dies. SQL server session is hung waiting for the web server process to read the data set. SQL Server sessions that need to get X locks on parts of the claim table (anyone processing claims) are blocked by the lock on the claim table and remain blocked until they all hit the application time out. Any suggestions for troubleshooting while waiting for the vendor's assistance would be most welcome. Is there a way to force SQL Server to lock at the row/page level for this particular SQL statement only? Is there a way to set a threshold on ASYNC_NETWORK_IO waits only?

  • Openfire and LDAP issues

    - by clsmith
    Thanks in advance for the help. Has anyone see this issue with openfire? Currently I use Openfire Fedora with Auth using windows 2003 and also use mysql for the database. When I bring up two clients and talk to each other the time is slow between messages. Sometimes it can take between 5-15 minutes for something sent to get to the person (this is with only two people on the openfire server). I ran a tcp dump using port 389 and see that the machine is running thousands of queries against ldap. When i plug it into wireshark I notice that it is transferring the entire contact list or checking on the status of the entire contact list ? When I run debug on openfire itself I am presented with only this small message in the log: 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Trying to find a groups's DN based on it's groupname. cn: Spark agents CLT, Base DN: OU="Hidden",DC="Hidden",DC="net"... 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished 2010.06.08 07:01:17 LdapManager: Trying to find a groups's DN based on it's groupname. cn: Spark agents CLT, Base DN: OU="Hidden",DC="Hidden",DC="net"... 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished I thought this was a configuration on my end and started to look into the cache settings on the openfire webpages. I tweaked the settings as recommend by the pages and still get the same issues. I doesnt seem to cache the contact list or this might be a feature never fixed or implemented. Has anyone gone through this before ? I have searched online and I see others have great experience with openfire with no issues like I have, or is it because noone checked the queries ? For the time being I created a new Domain Controller and moved openfire to that computer so it can run local queries. This seems to help reduce the speed alot, but when I run the server performance manager tool I see that with two people only using that openfire server I run 593.7 request per second. Thanks for your help, if I didnt provide enough data please let me know what you need and I can find it.

  • Java Refuses to Start - Could not reserve enough space for object heap

    - by Randyaa
    Background We have a pool of aproximately 20 linux blades. Some are running Suse, some are running Redhat. ALL share NAS space which contains the following 3 folders: /NAS/app/java - a symlink that points to an installation of a Java JDK. Currently version 1.5.0_10 /NAS/app/lib - a symlink that points to a version of our application. /NAS/data - directory where our output is written All our machines have 2 processors (hyperthreaded) with 4gb of physical memory and 4gb of swap space. We limit the number of 'jobs' each machine can process at a given time to 6 (this number likely needs to change, but that does not enter into the current problem so please ignore it for the time being). Some of our jobs set a Max Heap size of 512mb, some others reserve a Max Heap size of 2048mb. Again, we realize we could go over our available memory if 6 jobs started on the same machine with the heap size set to 2048, but to our knowledge this has not yet occurred. The Problem Once and a while a Job will fail immediately with the following message: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. We used to chalk this up to too many jobs running at the same time on the same machine. The problem happened infrequently enough (MAYBE once a month) that we'd just restart it and everything would be fine. The problem has recently gotten much worse. All of our jobs which request a max heap size of 2048m fail immediately almost every time and need to get restarted several times before completing. We've gone out to individual machines and tried executing them manually with the same result. Debugging It turns out that the problem only exists for our SuSE boxes. The reason it has been happening more frequently is becuase we've been adding more machines, and the new ones are SuSE. 'cat /proc/version' on the SuSE boxes give us: Linux version 2.6.5-7.244-bigsmp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005 'cat /proc/version' on the RedHat boxes give us: Linux version 2.4.21-32.0.1.ELsmp ([email protected]) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)) #1 SMP Tue May 17 17:52:23 EDT 2005 'uname -a' gives us the following on BOTH types of machines: UTC 2005 i686 i686 i386 GNU/Linux No jobs are running on the machine, and no other processes are utilizing much memory. All of the processes currently running might be using 100mb total. 'top' currently shows the following: Mem: 4146528k total, 3536360k used, 610168k free, 132136k buffers Swap: 4194288k total, 0k used, 4194288k free, 3283908k cached 'vmstat' currently shows the following: procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 610292 132136 3283908 0 0 0 2 26 15 0 0 100 0 If we kick off a job with the following command line (Max Heap of 1850mb) it starts fine: java/bin/java -Xmx1850M -cp helloworld.jar HelloWorld Hello World If we bump up the max heap size to 1875mb it fails: java/bin/java -Xmx1875M -cp helloworld.jar HelloWorld Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. It's quite clear that the memory currently being used is for Buffering/Caching and that's why so little is being displayed as 'free'. What isn't clear is why there is a magical 1850mb line where anything higher means Java can't start. Any explanations would be greatly appreciated.

  • Slide div inside another div effect

    - by mariki
    I am trying to create sliding images effect: Online demolink text. The problem is when you click rapidly and randomly on the buttons and not wait for animation to finish causing unpredicted results and even stopping the functionality to work. (and once it stopped in the middle of 2 images...) How Can I make it work without bugs? I know that there are some other tools for that sliding like jquery and other approaches like changing the position attribute and not the scrollLeft attribute. But I want to do it as it is, with scrollLeft, if it possible of course. The Code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Untitled Document</title> <style type="text/css"> body { padding:0px; margin:0px; } #imageContainer { width: 500px; position: relative; } #div { overflow: hidden; white-space: nowrap; } #div img { cursor: pointer; vertical-align: bottom; width: 500px; padding:0px; margin:0px; display:inline; } </style> <script type="text/javascript"> var scrollIntervalID; var currentIndex=0; function Scroll(ind){ var dir = ind ==currentIndex?0:ind<currentIndex?-1:1; var steps = Math.abs(ind-currentIndex); scrollIntervalID = setInterval(function(){ var i=(steps*10)-1; return function(){ if (i <= 0) clearInterval(scrollIntervalID); var elm = document.getElementById("div"); elm.scrollLeft +=dir * 50; i--; document.getElementById("span").innerHTML=elm.scrollLeft; } }(), 15); currentIndex=ind; } </script> </head> <body> <div id="imageContainer"> <div id="div"> <img id="image1" src="Images/pic1.jpg" width="500px"/><img id="image2" src="Images/pic2.jpg" width="500px"/><img id="image3" src="Images/pic3.jpg" width="500px"/><img id="image4" src="Images/pic4.jpg" width="500px"/> </div> </div> <div> <input type="button" value="1" onclick="Scroll(0);"/> <input type="button" value="2" onclick="Scroll(1);"/> <input type="button" value="3" onclick="Scroll(2);"/> <input type="button" value="4" onclick="Scroll(3);"/> </div> <span id="span"></span> </body> </html>

    i am using tcpdf to create pdf files with rows of table in the first page of pdf i display some info like : List of table .... and header of table after that i display the rows in table if there much rows it contiunes in the next page without the info [List of table... and header of table] i want to display the header of table only in the next pages here is my code $pdf->SetFont('aefurat', '', 15); $pdf->AddPage('P', 'A4'); $pdf->SetFontSize(17); $pdf->Cell(0, 13, 'List of the Byan Table,'C'); $pdf->SetFont('dejavusans', '', 14); $htmlpersian = 'In / Out List'; $pdf->WriteHTML($htmlpersian, true, 0, true, 0); $pdf->setRTL(false); $pdf->SetFontSize(11); $pdf->setRTL(true); Connect(); $resultsc = mysql_query("SELECT * FROM byan Order By Date "); while($r = mysql_fetch_array($resultsc)) { $printresult .= ' <tr> <td ><center>'.$r['Date'].'</center></td> <td ><center>'.$r['In'].'</center></td> <td ><center>'.$r['Out'].'</center></td> <td ><center>'.$r['Balance'].'</center></td> <td ><center>'.$r['Info'].'</center></td> <td ><center>'.$r['Number'].'</center></td> </tr>'; } $tbl = ' <table cellspacing="0" cellpadding="1" border="1" align="center"> <tr> <td style="width: 13%; background-color:black; color:white;"><center>Date</center></td> <td style="width: 11%; background-color:black; color:white;"><center>In</center></td> <td style="width: 11%; background-color:black; color:white;"><center>Out</center></td> <td style="width: 12%; background-color:black; color:white;"><center>Balance</center></td> <td style="width: 45%; background-color:black; color:white;"><center>Info</center></td> <td style="width: 11%; background-color:black; color:white;"><center>Number</center></td> </tr> '.$printresult.' </table> '; $pdf->writeHTML($tbl, true, false, true, false, ''); the output is First Page: List of the Byan Table In / Out List Table Header rows Second Page: Rows Third Page: Rows i want the output to be like that First Page: List of the Byan Table In / Out List Table Header Rows Second Page: Table Header Rows Third Page: Table Header Rows

  • Is Fast Enumeration messing with my text output?

    - by Dan Ray
    Here I am iterating through an array of NSDictionary objects (inside the parsed JSON response of the EXCELLENT MapQuest directions API). I want to build up an HTML string to put into a UIWebView. My code says: for (NSDictionary *leg in legs ) { NSString *thisLeg = [NSString stringWithFormat:@"<br>%@ - %@", [leg valueForKey:@"narrative"], [leg valueForKey:@"distance"]]; NSLog(@"This leg's string is %@", thisLeg); [directionsOutput appendString:thisLeg]; } The content of directionsOutput (which is an NSMutableString) contains ALL the values for [leg valueForKey:@"narrative"], wrapped up in parens, followed by a hyphen, followed by all the parenthesized values for [leg valueForKey:@"distance"]. So I put in that NSLog call... and I get the same thing there! It appears that the for() is somehow batching up our output values as we iterate, and putting out the output only once. How do I make it not do this but instead do what I actually want, which is an iterative output as I iterate? Here's what NSLog gets. Yes, I know I need to figure out NSNumberFormatter. ;-) This leg's string is ( "Start out going NORTH on INFINITE LOOP.", "Turn LEFT to stay on INFINITE LOOP.", "Turn RIGHT onto N DE ANZA BLVD.", "Merge onto I-280 S toward SAN JOSE.", "Merge onto CA-87 S via EXIT 3A.", "Take the exit on the LEFT.", "Merge onto CA-85 S via EXIT 1A on the LEFT toward GILROY.", "Merge onto US-101 S via EXIT 1A on the LEFT toward LOS ANGELES.", "Take the CA-152 E/10TH ST exit, EXIT 356.", "Turn LEFT onto CA-152/E 10TH ST/PACHECO PASS HWY.

  • Paging, sorting and filtering in a stored procedure (SQL Server)

    - by Fruitbat
    I was looking at different ways of writing a stored procedure to return a "page" of data. This was for use with the asp ObjectDataSource, but it could be considered a more general problem. The requirement is to return a subset of the data based on the usual paging paremeters, startPageIndex and maximumRows, but also a sortBy parameter to allow the data to be sorted. Also there are some parameters passed in to filter the data on various conditions. One common way to do this seems to be something like this: [Method 1] ;WITH stuff AS ( SELECT CASE WHEN @SortBy = 'Name' THEN ROW_NUMBER() OVER (ORDER BY Name) WHEN @SortBy = 'Name DESC' THEN ROW_NUMBER() OVER (ORDER BY Name DESC) WHEN @SortBy = ... ELSE ROW_NUMBER() OVER (ORDER BY whatever) END AS Row, ., ., ., FROM Table1 INNER JOIN Table2 ... LEFT JOIN Table3 ... WHERE ... (lots of things to check) ) SELECT * FROM stuff WHERE (Row > @startRowIndex) AND (Row <= @startRowIndex + @maximumRows OR @maximumRows <= 0) ORDER BY Row One problem with this is that it doesn't give the total count and generally we need another stored procedure for that. This second stored procedure has to replicate the parameter list and the complex WHERE clause. Not nice. One solution is to append an extra column to the final select list, (SELECT COUNT(*) FROM stuff) AS TotalRows. This gives us the total but repeats it for every row in the result set, which is not ideal. [Method 2] An interesting alternative is given here (http://www.4guysfromrolla.com/articles/032206-1.aspx) using dynamic SQL. He reckons that the performance is better because the CASE statement in the first solution drags things down. Fair enough, and this solution makes it easy to get the totalRows and slap it into an output parameter. But I hate coding dynamic SQL. All that 'bit of SQL ' + STR(@parm1) +' bit more SQL' gubbins. [Method 3] The only way I can find to get what I want, without repeating code which would have to be synchronised, and keeping things reasonably readable is to go back to the "old way" of using a table variable: DECLARE @stuff TABLE (Row INT, ...) INSERT INTO @stuff SELECT CASE WHEN @SortBy = 'Name' THEN ROW_NUMBER() OVER (ORDER BY Name) WHEN @SortBy = 'Name DESC' THEN ROW_NUMBER() OVER (ORDER BY Name DESC) WHEN @SortBy = ... ELSE ROW_NUMBER() OVER (ORDER BY whatever) END AS Row, ., ., ., FROM Table1 INNER JOIN Table2 ... LEFT JOIN Table3 ... WHERE ... (lots of things to check) SELECT * FROM stuff WHERE (Row > @startRowIndex) AND (Row <= @startRowIndex + @maximumRows OR @maximumRows <= 0) ORDER BY Row (Or a similar method using an IDENTITY column on the table variable). Here I can just add a SELECT COUNT on the table variable to get the totalRows and put it into an output parameter. I did some tests and with a fairly simple version of the query (no sortBy and no filter), method 1 seems to come up on top (almost twice as quick as the other 2). Then I decided to test probably I needed the complexity and I needed the SQL to be in stored procedures. With this I get method 1 taking nearly twice as long as the other 2 methods. Which seems strange. Is there any good reason why I shouldn't spurn CTEs and stick with method 3? UPDATE - 15 March 2012 I tried adapting Method 1 to dump the page from the CTE into a temporary table so that I could extract the TotalRows and then select just the relevant columns for the resultset. This seemed to add significantly to the time (more than I expected). I should add that I'm running this on a laptop with SQL Server Express 2008 (all that I have available) but still the comparison should be valid. I looked again at the dynamic SQL method. It turns out I wasn't really doing it properly (just concatenating strings together). I set it up as in the documentation for sp_executesql (with a parameter description string and parameter list) and it's much more readable. Also this method runs fastest in my environment. Why that should be still baffles me, but I guess the answer is hinted at in Hogan's comment.
