  • a:hover background-postition problem

    - by Ryan
    For some reason, I am not entirely sure why, but the following is not working. The background position simply stays the same on hover. I cannot figure out why. I could do it another way, but I would like to try and get to the bottom of why it does not work. #nav a:link, #nav a:visited { background:url(../img/nav-sprite.png) no-repeat; display:block; float:left; height:200px; padding:10px; text-indent:-9999px; border:solid 1px red; } #nav a#home { background-position:-10px 0px; width:30px; } #nav a#about-us { background-position:-85px 0px; width:45px; } #nav a:hover { background-position:1px -15px; } Does anybody know what could be causing this? Thanks in advance! Ryan

  • How to draw some lines in a view element defined in the xml layout

    - by Nils
    Hello, I have problems drawing some simple lines in a view object (Android programming). First I created the layout with the view element(kind of painting area) in it (XML file). [...] < View android:id="@+id/viewmap" android:layout_width="572px" android:layout_height="359px" android:layout_x="26px" android:layout_y="27px" [...] ... and tried then to access it to draw some lines. Unfortunately the program is running and other UI elements like buttons are displayed, but I can't see the drawings. What's wrong ? [...] viewmap = (View) findViewById(R.id.viewmap); Canvas canvas = new Canvas(); viewmap.draw(canvas); Paint p = new Paint(); p.setColor(Color.BLUE); p.setStyle(Paint.Style.STROKE); canvas.drawColor(Color.WHITE); p.setColor(Color.BLUE); canvas.drawLine(4, 4, 29, 5, p); p.setColor(Color.RED); viewmap.draw(canvas); [...] Thanks for help :) !

  • How can a ListBoxItem property be set in Silverlight at runtime?

    - by sympatric greg
    Given this XAML, I need to resize the userControl in response to user input. How can I set a new width for ListBoxItem (or perhaps the StackPanel)? <ScrollViewer x:Name="ScrollViewer" Margin="0" BorderBrush="Transparent" Width="165" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Hidden"> <ListBox x:Name="AttributeListBox" ItemsSource="{Binding Attributes}" BorderBrush="Red" Width="160" Foreground="AntiqueWhite" Background="Transparent" IsEnabled="False" HorizontalAlignment="Stretch"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalAlignment" Value="Stretch"/> <Setter Property="Width" Value="150"/> <Setter Property="Margin" Value="0,-2,0,0"/> <Setter Property="HorizontalContentAlignment" Value="Left" /> <Setter Property="Template" Value="{StaticResource ListBoxItemSansFocus}" /> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <StackPanel x:Name="ListBoxItemStackPanel" HorizontalAlignment="Stretch" Orientation="Vertical" > <TextBlock FontSize="10" Text="{Binding Key}" Foreground="White" FontWeight="Bold" HorizontalAlignment="Stretch" Margin="2,0,0,0" TextWrapping="Wrap"/> <TextBlock FontSize="10" Text="{Binding Value}" Foreground="White" Margin="6,-2,0,0" TextWrapping="Wrap"/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </ScrollViewer>

  • SWT - Table Row - Changing font color

    - by jkteater
    Is it possible to change the font color for a row based on a value in one of the columns? My table has a column that displays a status. The value of the column is going to either be Failed or Success. If it is Success I would like for that rows font be green. If the status equals Failed, I want that rows font be red. Is this possible, if so where would I put the logic. EDIT Here is my Table Viewer code, I am not going to show all the columns, just a couple private void createColumns() { String[] titles = { "ItemId", "RevId", "PRL", "Dataset Name", "Printer/Profile" , "Success/Fail" }; int[] bounds = { 100, 75, 75, 150, 200, 100 }; TableViewerColumn col = createTableViewerColumn(titles[0], bounds[0], 0); col.setLabelProvider(new ColumnLabelProvider() { public String getText(Object element) { if(element instanceof AplotResultsDataModel.ResultsData) { return ((AplotResultsDataModel.ResultsData)element).getItemId(); } return super.getText(element); } }); col = createTableViewerColumn(titles[1], bounds[1], 1); col.setLabelProvider(new ColumnLabelProvider() { public String getText(Object element) { if(element instanceof AplotResultsDataModel.ResultsData) { return ((AplotResultsDataModel.ResultsData)element).getRevId(); } return super.getText(element); } }); --ETC

  • Internet Explorer table 1 pixel spacing problem

    - by Dennis G.
    I've found a strange problem with Internet Explorer related to table spacing and cannot find a way to work around it. An empty table results in a single pixel white space with Internet Explorer (6 and 7, 8 not yet tested), while all other browsers ignore the empty table. Here's a picture of the problem: And here is the minimum HTML code to reproduce the issue (please note that there are more margin/padding css attributes and table attributes specified than really needed, I just tested if this fixes IE's behavior): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <body> <div style="width: 200px; border: 1px black solid"> <table border="0" cellspacing="0" cellpadding="0" style="margin: 0pt; padding: 0pt; border-collapse: collapse;"> <tr> <td style="padding: 0; margin: 0"> </td> </tr> </table> <div style="background: red"> Test </div> </div> </body> </html> I'm not using an empty table as specified in the example above, but this was the minimum code that displays this behavior. Any ideas on how to fix this and remove the white space with IE?

  • Over ride default look and feel Java

    - by Aizaz
    I want to over ride java look and feel. I just want to show the buttons differently. I want all the features of Windows Look and Feel but only buttons differently. I hope you get my point.

  • How do I get the element after my horizontal css navigation bar to appear below it?

    - by Curyous
    I'm using a css unordered list to make a site navigation bar, using display: inline, display: block, and float: left. The next element that I put after the navigation bar is placed to the right of it. How can I align the next element so that it is displayed below? The html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> <html> <head> <link type="text/css" rel="stylesheet" href="/stylesheets/test.css" /> </head> <body> <div> <ul class="nav"> <li class="nav"><a class="nav" href="#">One1</a></li> <li class="nav"><a class="nav" href="#">Two</a></li> <li class="nav"><a class="nav" href="#">Three</a></li> <li class="nav"><a class="nav" href="#">Four</a></li> </ul> </div> <div><h2>Heading</h2></div> </body> </html> The css: ul.nav, ul li.nav { display: inline; margin: 0px; padding: 0px; } ul.nav { list-style-type: none; } li.nav { display: block; float: left; background-color: red; } a.nav { background-color: green; padding: 10px; margin: 0px; } a:hover.nav { background-color: gray; }

  • How to format the Facebook news feed description of grouped app posts?

    - by JcFx
    I have an app which posts a message like this to a user's Facebook timeline: This is working fine, but if I post a few times, my posts get grouped on my news feed, and I get this: What settings should I use to control the way this news report appears? Instead of 'All about periods' and the page link in the box at the top, I'd like 'Body iQ Quiz' and the app description. Where would I set these values? And is it possible to make the grouped report say 'Jay cee Effex shared a link via Body iQ Quiz', the way the original post does? I'm posting from the Facebook AS3 API, and my post code looks like this: var auth:FacebookAuthResponse = Facebook.getAuthResponse(); var token:String = auth.accessToken; var user:String = auth.uid; var values:Object = { access_token: token, name: "Body iQ Quiz", picture: "http://a7.sphotos.ak.fbcdn.net/hphotos-ak-snc6/282950_427728213914009_630526316_n.jpg", link:"http://www.lil-lets.co.uk/en-GB/Wellbeing", description: "Women, how well do we know our bodies? Click here to find out what your Body iQ is.", message: result.FacebookBody + " " + result.FacebookTitle }; Facebook.api("/" + user + "/feed", handleSubmitFeed, values, URLRequestMethod.POST); ... but I'm not sure if this is something I can fix in code, or if the app configuration needs tweaking? NOTE: Some users report getting the latter format in their news feed even with a single post (I can't reproduce this), so perhaps grouping is a red herring, and the real question is how to format the news feed report of a timeline post?

  • emacs: Inferior-mode python-shell appears "lagged"

    - by Begbie00
    Hi all - I'm a Python(3.1.2)/emacs(23.2) newbie teaching myself tkinter using the pythonware tutorial found here. Relevant code is pasted below the question. Question: when I click the Hello button (which should call the say_hi function) why does the inferior python shell (i.e. the one I kicked off with C-c C-c) wait to execute the say_hi print function until I either a) click the Quit button or b) close the root widget down? When I try the same in IDLE, each click of the Hello button produces an immediate print in the IDLE python shell, even before I click Quit or close the root widget. Is there some quirk in the way emacs runs the Python shell (vs. IDLE) that causes this "lagged" behavior? I've noticed similar emacs lags vs. IDLE as I've worked through Project Euler problems, but this is the clearest example I've seen yet. FYI: I use python.el and have a relatively clean init.el... (setq python-python-command "d:/bin/python31/python") is the only line in my init.el. Thanks, Mike === Begin Code=== from tkinter import * class App: def __init__(self,master): frame = Frame(master) frame.pack() self.button = Button(frame, text="QUIT", fg="red", command=frame.quit) self.button.pack(side=LEFT) self.hi_there = Button(frame, text="Hello", command=self.say_hi) self.hi_there.pack(side=LEFT) def say_hi(self): print("hi there, everyone!") root = Tk() app = App(root) root.mainloop()

  • Dependency Property ListBox

    - by developer
    Hi All, I want to use a dependency property, so that my label displays values selected in the listbox. This is just to more clearly understand the working of a dependency property. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WPFToolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" xmlns:local="clr-namespace:WpfApplication1" x:Name="MyWindow" Height="200" Width="300" > <StackPanel> <ListBox x:Name="lbColor" Width="248" Height="56" ItemsSource="{Binding TestColor}"/> <StackPanel> <Label Content="{Binding Path=Test, ElementName=lbColor}" /> </StackPanel> </StackPanel> </Window> Code Behind, namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public ObservableCollection<string> TestColor { get; set; } public String Test { get { return (String)GetValue(TestProperty); } set { SetValue(TestProperty, value); } } // Using a DependencyProperty as the backing store for Title.

Somehow I am very confused with the Dependency Property concept, and I just wanted to see a working example for that.

  • Google Script / Spreadsheet -- Shared permissions with Installed Trigger onEdit

    - by user1761852
    Using an installed trigger inside spreadsheet to call onUpdateBilling(). Purpose of this script is on edit, based on content of column "billed" (i.e. "d") will highlight the entire column the predetermined color. Page running script is shared with collaborators and they have been given edit access. My expectation at this point is the script should be run with owner permissions. My shared users are unable to run the script with the given error "You don't have permission for this action." Reached my limited knowledge and googlefu for this workaround. Any help to allow operation to my collaborators is appreciated. Script: function onUpdateBilling(e) { var statusCol = 16; // replace with the column index of Status column A=1,B=2,etc var sheetName = "Temple Log"; // replace with actual name of sheet containing Status var cell = SpreadsheetApp.getActiveSheet().getActiveCell(); var sheet = cell.getSheet(); if(cell.getColumnIndex() != statusCol || sheet.getName() != sheetName) return; var row = cell.getRowIndex(); var status = cell.getValue(); // change colors to meet your needs var color; if (status == "D" || status == "d") { color = "red";} else if (status >= 1) { color = "yellow";} else if (status == "X" || status == "x") { color = "black";} else if (status == "") { color = "white";} else { color = "white"; } sheet.getRange(row + ":" + row ).setBackgroundColor(color); }

  • Passing a var as an argument

    - by Lienau
    On a site I'm making I need to have a progress bar, I found one that suited my needs. By default it will incrementally change the color when a certain percentage is reached (0-30 red, 30-70 orange, etc). My only problem is changing them, I can set them easily with a static number such as 50, but when I try to do it dynamically (ie: 2000*.3 = 600) it fails. I don't know much js/jquery so this is especially difficult for me, if you could help that would be great. I'm pretty sure it's something really simple I'm missing. The code that Fails: var barmax = 2000; var orangeBound = Math.round(barmax * .3); var greenBound = Math.round(barmax * .7); //alert(orangeBound+":"+greenBound); $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', orangeBound: 'images/progressbg_orange.gif', greenBound: 'images/progressbg_green.gif'} }); The code that works but I can't use because it has to be dynamic: $("#pb1").progressBar({ max: barmax, textFormat: 'fraction', barImage: { 0: 'images/progressbg_red.gif', 600: 'images/progressbg_orange.gif', 1400: 'images/progressbg_green.gif'} }); If you need to see the source, here. Thanks again!

  • How should backbone.js handle a GET request that returns no results?

    - by Nyxynyx
    I have a number of text input elements that when its values are changed, will trigger a fetch on listingListView's collection listingCollection, which then updates listingListView with the new data via the function listingListView.refreshList as shown below. I am using PHP/Codeigniter to expose a RESTful API. Problem: Everything works fine if there are results retrieved from the fetch(). However, when the filters results in no result being returned, how should the server side and the client side handle it? Currently Chrome's javascript console displays a 404 error and in the Network tab, the XHR request is highlighted in red. All I want to do in the event of zero results returned, is to blank the listingListView and show a message like (No results returned) and not throw any errors in the javascript console. Thanks! PHP Code function listings_get() { // Get filters $price_min = $this->get('price_min'); $this->load->model('app_model'); $results = $this->app_model->get_listings($price_min); if($results) $this->response($results); else $this->response(NULL); } JS Code window.ListingListView = Backbone.View.extend({ tagName: 'table', initialize: function() { this.model.bind('reset', this.refreshList, this); this.model.bind('add', function(listing) { $(this.el).append(new ListingListItemView({ model: listing }).render().el); }, this); }, render: function() { _.each(this.model.models, function(listing) { $(this.el).append(new ListingListItemView({ model: listing }).render().el); }, this); return this; }, close: function() { $(this.el).unbind(); $(this.el).empty(); }, refreshList: function() { $(this.el).empty(); this.render(); } });

  • SVN supports historical merges so how is Mercurial better?

    - by radman
    Hi, I'm a long time SVN user and have been hearing a lot of brou ha ha with regard to mercurial and decentralised version control systems in general. The main touted feature that I am aware of is that merging in Mercurial is much easier because it records information for each merge so each successive merge is aware of the previous ones. Now as stated in the red book, in the section to do with merging, SVN already supports this with mergeinfo. Now I have not actually used this feature (although I wanted to, our repo version wasn't recent enough) but is this SVN feature particularly different to what Mercurial offers? For anyone who is not aware the suggested work flow for historical merging in svn is this: branch from the development trunk to do your own thing. Regularly merge changes from trunk into your branch to stay up to date. Merge back when your done with the mergeinfo to smooth the process. Without historical data merging this is a nightmare because the comparison is strictly on the differences in the files and does not take into account the steps taken on the way. So each change in the development trunk puts you further into possible conflict when you merge back. Now what I would like to know is: Does merging using Mercurial provide a significant advantage when compared with mergeinfo in SVN or is this just a lot of hot air about nothing? Has anyone used the mergeinfo feature in SVN and how good is it actually in practice?

  • Why is the label not changing color using RegisterClientScriptBlock?

    - by Xaisoft
    I have an aspx page defined as follows: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript" language='javascript'> function changecolor() { var lbl = document.getElementById('lblDisplayDate'); lbl.style.color = 'red'; }; </script> </head> <body> <form id="form1" runat="server"> <div> <asp:Label ID="lblDisplayDate" runat="server" Text="Label"></asp:Label><br /> <asp:Button ID="btnPostBack2" runat="server" Text="Register Client Block Script" onclick="btnPostBack2_Click" /> </div> </form> Here is the btnPostBack2 Click event: protected void btnPostBack2_Click(object sender, EventArgs e) { if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock")) { ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", "changecolor();", true); } } Even though, I put the script in a function to change the color, it is still not doing it and why do I need to add the script tags to true if the function is already enclosed in script tags? lblDisplayDate is in the Page Load where it is set to the current time on every page reload.

  • How does asp.net MVC remember my incorrect values on postback?

    - by Michel
    This is working, but how??? I have a controller action for a post: [AcceptVerbs(HttpVerbs.Post )] public ActionResult Edit(Person person) { bool isvalid = ModelState.IsValid; etc. The Person object has a property BirthDate, type DateTime. When i enter some invalid data in the form, say 'blabla' which is obvious not a valid Datetime, it fills all the (other) Person properties with the correct data and the BirthDate property with a new blank DateTime. The bool isvalid has the value 'false'. So far so good. Then i do this: return View(p); and in the view i have this: <%= Html.TextBox("BirthDate", String.Format("{0:g}", Model.BirthDate)) %> <%= Html.ValidationMessage("BirthDate", "*") %> Ant there it comes: i EXPECTED the model to contain the new, blank DateTime because i didn't put any new data in. Second, when the View displays something, it must be a DateTime, because Model.BirthDate can't hold anything but a DateTime. But to my surprise, it shows a textbox with the 'blabla' value! (and the red * behind it) Which ofcourse is nice because the user can seee what he typed wrong, but how can that (blabla)string be transferred to the View in a DateTime field?

  • (Not So) Silly Objective-C inheritance problem when using property - GCC Bug?

    - by Ben Packard
    Update 2 - Many people are insisting I need to declare an iVar for the property. Some are saying not so, as I am using Modern Runtime (64 bit). I can confirm that I have been successfully using @property without iVars for months now. Therefore, I think the 'correct' answer is an explanation as to why on 64bit I suddenly have to explicitly declare the iVar when (and only when) i'm going to access it from a child class. The only one I've seen so far is a possible GCC bug (thanks Yuji). Not so simple after all... Update - I messed up one line of the original copy and paste - corrected. The @property call was missing (nonatomic, retain) but is a red herring - STILL NEED AN ANSWER! Thanks. I've been scratching my head with this for a couple of hours - I haven't used inheritance much. Here I have set up a simple Test B class that inherits from Test A, where an ivar is declared. But I get the compilation error that the variable is undeclared. This only happens when I add the property and synthesize declarations - works fine without them. TestA Header: #import <Cocoa/Cocoa.h> @interface TestA : NSObject { NSString *testString; } @end TestA Implementation is empty: #import "TestA.h" @implementation TestA @end TestB Header: #import <Cocoa/Cocoa.h> #import "TestA.h" @interface TestB : TestA { } @property (nonatomic, retain) NSString *testProp; @end TestB Implementation (Error - 'testString' is undeclared) #import "TestB.h" @implementation TestB @synthesize testProp; - (void)testing{ NSLog(@"test ivar is %@", testString); } @end

  • CSS ] how to automatically resize the wrapper div.

    - by Phrixus
    Hi, I've been struggling with this problem.. There is a wrapper div and it contains 3 vertical column divs with full of texts, and this wrapper div has red background color so that it can be a background of the entire texts. <div id="content_wrapper"> <div id="cside_a"> // massive texts goes here </div> ... // two more columns go here. </div> And here is the CSS code for them. #content_wrapper { background-color:#DB0A00; background-repeat:no-repeat; min-height:400px; } #cside_a, #cside_b, #cside_c { float: left; width: 33%; } And this code gives me a background that covers only 400px height box.. My expectation was the wrapper div automatically resizes depending on the size of the divs in it. Somehow putting "overflow:hidden" with wrapper CSS code makes everything work fine. I have no idea why "overflow:hidden" works.. shouldn't this hide all the overflowed texts..? Could anyone explain me why? Is is the correct way to do it anyway?

  • Strategy for animating a lot of "LED's" - thread?, UIView animations? NSOperation? (iPhone)

    - by RickiG
    Hi I have to do some different views containing 72 LED lights. I built an LED Class so I can loop through the LED's and set them to different colors (Green, Red, Orange, Blue None etc.). The LED then loads the appropriate .png. This works fine, I loop over the LED's and set them. Now I know that at some time they will need to not just turn on/off change color, but will have to turn on with a small delay. Like an equalizer. I have a 5-10 views containing the 72 LED's and I would like to achieve the above with the minimum amount of memory/CPU strain. for(LED *l in self.ledArray) { [l display:Green]; } I simply loop as shown above and inside the LED is a switch case that does the correct logic. If this were actual LED's and a microController I would use sleep(100) or similar in the loop, but I would really like to avoid stuff like that for obvious reasons. I was thinking that doing a performOnThread withDelay would really be consuming, so would UIView animation changing the alpha and NSOperation would also be a lot of lifting for a small feature. Is there a both efficient and clever way to go around this? Thanks for any inspiration given:)

  • lost session after redirect_to

    - by PeterWong
    I encountered a strange performance in my current project, which is about session. The strange part is it was normal in Safari but failed in other browsers (includes chrome, firefox and opera). There is a registration form for input of part of the key information (email, password, etc) and is submitted to an action called "create" This is the basic code of create action: @account = Account.new(params[:account]) if @account.save ApplicationController.current_account = @account session[:current_account] = ApplicationController.current_account session[:account] = ApplicationController.current_account.id email = @account.email Mailer.deliver_account_confirmation(email) flash[:type] = "success" flash[:notice] = "Successfully Created Account" redirect_to :controller => "accounts", :action => "create_step_2" else flash[:type] = "error" flash[:title] = "Oops, something wasn't right." flash[:notice] = "Mistakes are marked below in red. Please fix them and resubmit the form. Thanks." render :action => "new" end Also I created a before_filter in the application controller, which has the following code: ApplicationController.current_account = Account.find_by_id(session[:current_account].id) unless session[:current_account].blank? For Safari, there is no any problem. But for the other browsers, the session[:current_account] does not exist and so produced the following error message: RuntimeError in AccountsController#create_step_2 Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id Please could anyone help me?

  • Images in Applet not showing in web page

    - by Leanne C
    I am trying to display a JPEG image and a moving dot on a Java applet which I am using on a web based application. However, when I run the applet it works fine, but when I display the applet from the JSP page, I get the moving dot but not the JPEG image. Is there a specific folder where the JPEG needs to be? These are the 2 methods i use for drawing the picture and the moving dot on the screen. public class mapplet extends Applet implements Runnable { int x_pos = 10; int y_pos = 100; int radius = 20; Image img, img2; Graphics gr; URL base; MediaTracker m; @Override public void init() { mt = new MediaTracker(this); try { //getDocumentbase gets the applet path. base = getCodeBase(); img = getImage(base, "picture.jpg"); m.addImage(img, 1); m.waitForAll(); } catch (InterruptedException ex) { Logger.getLogger(movement.class.getName()).log(Level.SEVERE, null, ex); } public void paint (Graphics g) { g.drawImage(img, 0, 0, this); // set color g.setColor (Color.red); // paint a filled colored circle g.fillOval (x_pos - radius, y_pos - radius, 2 * radius, 2 * radius); } The code one below is the call from the jsp page <applet archive="mapplet.jar" code="myapplets/mapplet.class" width=350 height=200> </applet> The jar file and the picture are in the same folder as the jsp page, and there is also a folder containing the contents of the class and image of the applet in the web section of the application. The applet loads fine however the picture doesn't display. I think it's not the code but the location of the picture that is causing a problem. Thanks

    Putting a set of code which is pushing image to database and fetching back from database: <!-- <?php error_reporting(0); // Connect to database $errmsg = ""; if (! @mysql_connect("localhost","root","")) { $errmsg = "Cannot connect to database"; } @mysql_select_db("test"); $q = <<<CREATE create table image ( pid int primary key not null auto_increment, title text, imgdata longblob, friend text) CREATE; @mysql_query($q); // Insert any new image into database if (isset($_POST['submit'])) { move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img"); $instr = fopen("latest.img","rb"); $image = addslashes(fread($instr,filesize("latest.img"))); if (strlen($instr) < 149000) { $image_query="insert into image (title, imgdata,friend) values (\"". $_REQUEST['title']. "\", \"". $image. "\",'".$_REQUEST['friend']."')"; mysql_query ($image_query) or die("query error"); } else { $errmsg = "Too large!"; } $resultbytes=''; // Find out about latest image $query = "select * from image where pid=1"; $result = @mysql_query("$query"); $resultrow = @mysql_fetch_assoc($result); $gotten = @mysql_query("select * from image order by pid desc limit 1"); if ($row = @mysql_fetch_assoc($gotten)) { $title = htmlspecialchars($row[title]); $bytes = $row[imgdata]; $resultbytes = $row[imgdata]; $friend=$row[friend]; } else { $errmsg = "There is no image in the database yet"; $title = "no database image available"; // Put up a picture of our training centre $instr = fopen("../wellimg/ctco.jpg","rb"); $bytes = fread($instr,filesize("../wellimg/ctco.jpg")); } if ($resultbytes!='') { echo $resultbytes; } } ?> <html> <head> <title>Upload an image to a database</title> </head> <body bgcolor="#FFFF66"> <form enctype="multipart/form-data" name="file_upload" method="post"> <center> <div id="image" align="center"> <h2>Heres the latest picture</h2> <font color=red><?php echo $errmsg; ?></font> <b><?php echo $title ?></center> </div> <hr> <h2>Please upload a new picture and title</h2> <table align="center"> <tr> <td>Select image to upload: </td> <td><input type="file" name="imagefile"></td> </tr> <tr> <td>Enter the title for picture: </td> <td><input type="text" name="title"></td> </tr> <tr> <td>Enter your friend's name:</td> <td><input type="text" name="friend"></td> </tr> <tr> <td><input type="submit" name="submit" value="submit"></td> <td></td> </tr> </table> </form> </body> </html> --> Above set of code has one problem. The problem is whenever i pressing the "submit" button. It is just displaying the image on a page. But it is leaving all the html codes. even any new line message after the // Printing image on browser echo $resultbytes; //************************// So, for this i put this set of code in html tag: This is other sample code: <!-- <?php error_reporting(0); // Connect to database $errmsg = ""; if (! @mysql_connect("localhost","root","")) { $errmsg = "Cannot connect to database"; } @mysql_select_db("test"); $q = <<<CREATE create table image ( pid int primary key not null auto_increment, title text, imgdata longblob, friend text) CREATE; @mysql_query($q); // Insert any new image into database if (isset($_POST['submit'])) { move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img"); $instr = fopen("latest.img","rb"); $image = addslashes(fread($instr,filesize("latest.img"))); if (strlen($instr) < 149000) { $image_query="insert into image (title, imgdata,friend) values (\"". $_REQUEST['title']. "\", \"". $image. "\",'".$_REQUEST['friend']."')"; mysql_query ($image_query) or die("query error"); } else { $errmsg = "Too large!"; } $resultbytes=''; // Find out about latest image $query = "select * from image where pid=1"; $result = @mysql_query("$query"); $resultrow = @mysql_fetch_assoc($result); $gotten = @mysql_query("select * from image order by pid desc limit 1"); if ($row = @mysql_fetch_assoc($gotten)) { $title = htmlspecialchars($row[title]); $bytes = $row[imgdata]; $resultbytes = $row[imgdata]; $friend=$row[friend]; } else { $errmsg = "There is no image in the database yet"; $title = "no database image available"; // Put up a picture of our training centre $instr = fopen("../wellimg/ctco.jpg","rb"); $bytes = fread($instr,filesize("../wellimg/ctco.jpg")); } } ?> <html> <head> <title>Upload an image to a database</title> </head> <body bgcolor="#FFFF66"> <form enctype="multipart/form-data" name="file_upload" method="post"> <center> <div id="image" align="center"> <h2>Heres the latest picture</h2> <?php if ($resultbytes!='') { // Printing image on browser echo $resultbytes; } ?> <font color=red><?php echo $errmsg; ?></font> <b><?php echo $title ?></center> </div> <hr> <h2>Please upload a new picture and title</h2> <table align="center"> <tr> <td>Select image to upload: </td> <td><input type="file" name="imagefile"></td> </tr> <tr> <td>Enter the title for picture: </td> <td><input type="text" name="title"></td> </tr> <tr> <td>Enter your friend's name:</td> <td><input type="text" name="friend"></td> </tr> <tr> <td><input type="submit" name="submit" value="submit"></td> <td></td> </tr> </table> </form> </body> </html> --> ** But in this It is showing the image in format of special charaters and digits. 1) So, Please help me to print the image with some HTML code. So that i can print it in my form to display the image. 2) Is there any way to convert the database image into real image, so that i can store it into my hard-disk and call it from tag? Please help me.

  • Android - Temporal & Ancestral Navigation with ViewPager & Fragments

    - by rascuache
    I'm trying to work out the best way to implement the 'ancestral' and 'temporal' navigation (utilising the up button and back buttons), for a music player I'm working on. Currently, the user is presented with a viewpager, and can page between three main fragments (ArtistMain, AlbumMain and SongMain). Upon choosing an item inside that view, a fragment transaction occurs, and the viewpager goes out of view, replaced by a new fragment (AlbumSub, Songsub or player, depending on where the user came from). The user can then navigate deeper, until a song is chosen, and then they are taken to the 'player' screen. I guess the question is: How do I implement all of this conditional navigation? I'm fairly new to android and programming in general, and I just can't seem to come up with an efficient way to achieve this. At the moment, as each fragment is brought into view, the app is checking to see where the user just came from, and then determines where the user should be taken if back or home is called. This means I have a booleans like "fromArtistMain", "fromAlbumSub", and I'm checking for things like "fromSongSub && fromPlayer".. it's all turning into a bit of a mess. I've drawn a diagram (in paint, sorry!!), to depict the navigation I'm trying to achieve. The yellow represents the 'up' button press, the red is the 'back' button press, and blue is just normal navigation. The green arrows are meant to represent the view paging: Any advice is welcome. It might take something really simple that I've just overlooked. Thanks for your time.

  • UITouch Events and Table Views

    - by Andy
    I'm working on a navigation-based iPhone-only app that serves two main purposes: One, to present data in a hierarchical view, allowing users to drill down and eventually edit said data, and, two, to all users to perform a default action when the table view cell is tapped. I now need to offer a small set of options tied to the same data; however, both the didSelectRowAtIndexPath: and accessoryButtonTappedForRowAtIndexPath: methods are obviously taken. So, my options seem to be to implement a double-tap method, wherein the small list of additional options would be presented after (you guessed it) a double-tap on said table row; or, preferably, a tap-and-hold method. From what I can tell, tap-and-hold seems like the way to go in SDK 4.0 - which does me no good right this red-hot minute. I decided to go with the double-tap option, but I'm having a little trouble. First and foremost, the touchesBegan:withEvent: method does not seem to be getting called at all; a breakpoint placed within the method is never called while the application runs, and the table view responds exactly as it did before I inserted the method (which is to say, it performs the default action): - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *aTouch = [touches anyObject]; if (aTouch.tapCount == 2) { [NSObject cancelPreviousPerformRequestsWithTarget:self]; } } Second, I don't really need to handle a single-tap - the didSelectRowAtIndexPath: method can handle the single-tap just fine. The double-tap is the funky one I want to handle. I suspect the answer is going to contain the phrase, "You can't have the table view handle the single-tap and the touchesBegan: method handle the double-tap. The touch handling methods have to handle all of them." I would really appreciate some guidance from some of you who've dealt with this issue. Thanks in advance.

  • NullPointerException in NetBeans 6.5 IDE itself

    - by titaniumdecoy
    When I use NetBeans for almost any task (in particular, attempting to open a project), a red minus sign in the bottom right corner of the IDE starts blinking and I get the following NullPointerException error when I click it.
