  • Trouble Percent-Encoding Spaces in Java

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

  • WinMo > ASMX WebException - how to get details?

    - by eidylon
    Okay, we've got an application which consists of a website hosting several ASMX webservices, and a handheld application running on WinMo 6.1 which calls the webservices. Been developing in the office, everything works perfect. Now we've gone to install it at the client's and we got all the servers set up and the handhelds installed. However the handhelds are now no longer able to connect to the webservice. I added in extra code in my error handler to specifically trap WebException exceptions and handle them differently in the logging to put out extra information (.Status and .Response). I am getting out the status, which is returning a [7], or ProtocolError. However when I try to read out the ResponseStream (using WebException.Response.GetResponseStream), it is returning a stream with CanRead set to False, and I thus am unable to get any further details of what is going wrong. So I guess there are two things I am asking for help with... a) Any help with trying to get more information out of the WebException? b) What could be causing a ProtocolError exception? Things get extra complicated by the fact that the client has a full-blown log-in-enabled proxy setup going on-site. This was stopping all access to the website initially, even from a browser. So we entered in the login details in the network connection for HTTP on the WinMo device. Now it can get to websites fine. In fact, I can even pull up the webservice fine and call the methods from the browser (PocketIE). So I know the device is able to see the webservices okay via HTTP. But when trying to call them from the .NET app, it throws ProtocolError [7]. Here is my code which is logging the exception and failing to read out the Response from the WebException. Public Sub LogEx(ByVal ex As Exception) Try Dim fn As String = Path.Combine(ini.CorePath, "error.log") Dim t = File.AppendText(fn) t.AutoFlush = True t.WriteLine(<s>===== <%= Format(GetDateTime(), "MM/dd/yyyy HH:mm:ss") %> =====<%= vbCrLf %><%= ex.Message %></s>.Value) t.WriteLine() t.WriteLine(ex.ToString) t.WriteLine() If TypeOf ex Is WebException Then With CType(ex, WebException) t.WriteLine("STATUS: " & .Status.ToString & " (" & Val(.Status) & ")") t.WriteLine("RESPONSE:" & vbCrLf & StreamToString(.Response.GetResponseStream())) End With End If t.WriteLine("=".Repeat(50)) t.WriteLine() t.Close() Catch ix As Exception : Alert(ix) : End Try End Sub Private Function StreamToString(ByVal s As IO.Stream) As String If s Is Nothing Then Return "No response found." // THIS IS THE CASE BEING EXECUTED If Not s.CanRead Then Return "Unreadable response found." Dim rv As String = String.Empty, bytes As Long, buffer(4096) As Byte Using mem As New MemoryStream() Do While True bytes = s.Read(buffer, 0, buffer.Length) mem.Write(buffer, 0, bytes) If bytes = 0 Then Exit Do Loop mem.Position = 0 ReDim buffer(mem.Length) mem.Read(buffer, 0, mem.Length) mem.Seek(0, SeekOrigin.Begin) rv = New StreamReader(mem).ReadToEnd() mem.Close() End Using Return rv.NullOf("Empty response found.") End Function Thanks in advance!

The error is below. "Invalid index 2 for this SqlParameterCollection with Count=2." But the error will not come if I comment State_id mapping field in the CityMapping file. I donot know what mistake is I did. If do not give the mapping Map(x = x.State_id); the value of this field is null, which is desired. Please help me how to solve this issue.

  • How can I make this Java code run faster?

    - by Martin Wiboe
    Hello all, I am trying to make a Java port of a simple feed-forward neural network. This obviously involves lots of numeric calculations, so I am trying to optimize my central loop as much as possible. The results should be correct within the limits of the float data type. My current code looks as follows (error handling & initialization removed): /** * Simple implementation of a feedforward neural network. The network supports * including a bias neuron with a constant output of 1.0 and weighted synapses * to hidden and output layers. * * @author Martin Wiboe */ public class FeedForwardNetwork { private final int outputNeurons; // No of neurons in output layer private final int inputNeurons; // No of neurons in input layer private int largestLayerNeurons; // No of neurons in largest layer private final int numberLayers; // No of layers private final int[] neuronCounts; // Neuron count in each layer, 0 is input // layer. private final float[][][] fWeights; // Weights between neurons. // fWeight[fromLayer][fromNeuron][toNeuron] // is the weight from fromNeuron in // fromLayer to toNeuron in layer // fromLayer+1. private float[][] neuronOutput; // Temporary storage of output from previous layer public float[] compute(float[] input) { // Copy input values to input layer output for (int i = 0; i < inputNeurons; i++) { neuronOutput[0][i] = input[i]; } // Loop through layers for (int layer = 1; layer < numberLayers; layer++) { // Loop over neurons in the layer and determine weighted input sum for (int neuron = 0; neuron < neuronCounts[layer]; neuron++) { // Bias neuron is the last neuron in the previous layer int biasNeuron = neuronCounts[layer - 1]; // Get weighted input from bias neuron - output is always 1.0 float activation = 1.0F * fWeights[layer - 1][biasNeuron][neuron]; // Get weighted inputs from rest of neurons in previous layer for (int inputNeuron = 0; inputNeuron < biasNeuron; inputNeuron++) { activation += neuronOutput[layer-1][inputNeuron] * fWeights[layer - 1][inputNeuron][neuron]; } // Store neuron output for next round of computation neuronOutput[layer][neuron] = sigmoid(activation); } } // Return output from network = output from last layer float[] result = new float[outputNeurons]; for (int i = 0; i < outputNeurons; i++) result[i] = neuronOutput[numberLayers - 1][i]; return result; } private final static float sigmoid(final float input) { return (float) (1.0F / (1.0F + Math.exp(-1.0F * input))); } } I am running the JVM with the -server option, and as of now my code is between 25% and 50% slower than similar C code. What can I do to improve this situation? Thank you, Martin Wiboe

  • drupal_get_form is not passing along node array

    - by ElectronicBlacksmith
    I have not been able to get drupal_get_form to pass on the node data. Code snippets are below. The drupal_get_form documentation (api.drupal.org) states that it will pass on the extra parameters. I am basing the node data not being passed because (apparently) $node['language'] is not defined in hook_form which causes $form['qqq'] not to be created and thus the preview button shows up. My goal here is that the preview button show up using path "node/add/author" but doesn't show up for "milan/author/add". Any alternative methods for achieving this goal would be helpful but the question I want answered is in the preceding paragraph. Everything I've read indicates that it should work. This menu item $items['milan/author/add'] = array( 'title' = 'Add Author', 'page callback' = 'get_author_form', 'access arguments' = array('access content'), 'file' = 'author.pages.inc', ); calls this code function get_author_form() { //return node_form(NULL,NULL); //return drupal_get_form('author_form'); return author_ajax_form('author'); } function author_ajax_form($type) { global $user; module_load_include('inc', 'node', 'node.pages'); $types = node_get_types(); $type = isset($type) ? str_replace('-', '_', $type) : NULL; // If a node type has been specified, validate its existence. if (isset($types[$type]) && node_access('create', $type)) { // Initialize settings: $node = array('uid' = $user-uid, 'name' = (isset($user-name) ? $user-name : ''), 'type' = $type, 'language' = 'bbb','bbb' = 'TRUE'); $output = drupal_get_form($type .'_node_form', $node); } return $output; } And here is the hook_form and hook_form_alter code function author_form_author_node_form_alter(&$form, &$form_state) { $form['author']=NULL; $form['taxonomy']=NULL; $form['options']=NULL; $form['menu']=NULL; $form['comment_settings']=NULL; $form['files']=NULL; $form['revision_information']=NULL; $form['attachments']=NULL; if($form["qqq"]) { $form['buttons']['preview']=NULL; } } function author_form(&$node) { return make_author_form(&$node); } function make_author_form(&$node) { global $user; $type = node_get_types('type', $node); $node = author_make_title($node); drupal_set_breadcrumb(array(l(t('Home'), NULL), l(t($node-title), 'node/' . $node-nid))); $form['authorset'] = array( '#type' = 'fieldset', '#title' = t('Author'), '#weight' = -50, '#collapsible' = FALSE, '#collapsed' = FALSE, ); $form['author_id'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'hidden', '#default_value' = $node-author_id, '#weight' = -20 ); $form['authorset']['last_name'] = array( '#type' = 'textfield', '#title' = t('Last Name'), '#maxlength' = 60, '#default_value' = $node-last_name ); $form['authorset']['first_name'] = array( '#type' = 'textfield', '#title' = t('First Name'), '#maxlength' = 60, '#default_value' = $node-first_name ); $form['authorset']['middle_name'] = array( '#type' = 'textfield', '#title' = t('Middle Name'), '#maxlength' = 60, '#default_value' = $node-middle_name ); $form['authorset']['suffix_name'] = array( '#type' = 'textfield', '#title' = t('Suffix Name'), '#maxlength' = 14, '#default_value' = $node-suffix_name ); $form['authorset']['body_filter']['body'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'textarea', '#title' = 'Describe Author', '#default_value' = $node-body, '#required' = FALSE, '#weight' = -19 ); $form['status'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['promote'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['name'] = array( '#type' = 'hidden', '#default_value' = $user-name ); $form['format'] = array( '#type' = 'hidden', '#default_value' = '1' ); // NOTE in node_example there is some addition code here not needed for this simple node-type $thepath='milan/author'; if($_REQUEST["theletter"]) { $thepath .= "/" . $_REQUEST["theletter"]; } if($node['language']) { $thepath='milan/authorajaxclose'; $form['qqq'] = array( '#type' = 'hidden', '#default_value' = '1' ); } $form['#redirect'] = $thepath; return $form; } That menu path coincides with this theme (PHPTemplate)

  • Round-twice error in .NET's Double.ToString method

    - by Jeppe Stig Nielsen
    Mathematically, consider for this question the rational number 8725724278030350 / 2**48 where ** in the denominator denotes exponentiation, i.e. the denominator is 2 to the 48th power. (The fraction is not in lowest terms, reducible by 2.) This number is exactly representable as a System.Double. Its decimal expansion is 31.0000000000000'49'73799150320701301097869873046875 (exact) where the apostrophes do not represent missing digits but merely mark the boudaries where rounding to 15 resp. 17 digits is to be performed. Note the following: If this number is rounded to 15 digits, the result will be 31 (followed by thirteen 0s) because the next digits (49...) begin with a 4 (meaning round down). But if the number is first rounded to 17 digits and then rounded to 15 digits, the result could be 31.0000000000001. This is because the first rounding rounds up by increasing the 49... digits to 50 (terminates) (next digits were 73...), and the second rounding might then round up again (when the midpoint-rounding rule says "round away from zero"). (There are many more numbers with the above characteristics, of course.) Now, it turns out that .NET's standard string representation of this number is "31.0000000000001". The question: Isn't this a bug? By standard string representation we mean the String produced by the parameterles Double.ToString() instance method which is of course identical to what is produced by ToString("G"). An interesting thing to note is that if you cast the above number to System.Decimal then you get a decimal that is 31 exactly! See this Stack Overflow question for a discussion of the surprising fact that casting a Double to Decimal involves first rounding to 15 digits. This means that casting to Decimal makes a correct round to 15 digits, whereas calling ToSting() makes an incorrect one. To sum up, we have a floating-point number that, when output to the user, is 31.0000000000001, but when converted to Decimal (where 29 digits are available), becomes 31 exactly. This is unfortunate. Here's some C# code for you to verify the problem: static void Main() { const double evil = 31.0000000000000497; string exactString = DoubleConverter.ToExactString(evil); // Jon Skeet, http://csharpindepth.com/Articles/General/FloatingPoint.aspx Console.WriteLine("Exact value (Jon Skeet): {0}", exactString); // writes 31.00000000000004973799150320701301097869873046875 Console.WriteLine("General format (G): {0}", evil); // writes 31.0000000000001 Console.WriteLine("Round-trip format (R): {0:R}", evil); // writes 31.00000000000005 Console.WriteLine(); Console.WriteLine("Binary repr.: {0}", String.Join(", ", BitConverter.GetBytes(evil).Select(b => "0x" + b.ToString("X2")))); Console.WriteLine(); decimal converted = (decimal)evil; Console.WriteLine("Decimal version: {0}", converted); // writes 31 decimal preciseDecimal = decimal.Parse(exactString, CultureInfo.InvariantCulture); Console.WriteLine("Better decimal: {0}", preciseDecimal); // writes 31.000000000000049737991503207 } The above code uses Skeet's ToExactString method. If you don't want to use his stuff (can be found through the URL), just delete the code lines above dependent on exactString. You can still see how the Double in question (evil) is rounded and cast.

  • Slide div inside another div effect

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

  • Templates and inheritance

    - by mariusz
    Hello, I have a big problem. I use additional controls for Wpf. One of them is Telerik RadWindow This control is already templated. Now I want to create custom Window with will inherit from RadWindow, and make custom template, eg. One base window will contains grid and two buttons, second base window will contain two grids (master - detail). The problem is that templates do not support inheritance. Perhaps is another way to template only the content of Winodow? My code, that doesn't work (empty window appears, so template doesn't apply) <Style TargetType="{x:Type local:TBaseRjWindow}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:TBaseRjContent}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <Grid Name="mGrid"> <Grid.ColumnDefinitions> <ColumnDefinition /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition MaxHeight="40" MinHeight="30" /> <RowDefinition MaxHeight="40" MinHeight="30" /> <RowDefinition Height="Auto" /> <RowDefinition MaxHeight="40" MinHeight="30" /> </Grid.RowDefinitions> <telerik:RadGridView Margin="10,10,10,10" Name="grid" Grid.Row="0" Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ScrollMode="Deferred" AutoGenerateColumns="False" Width="Auto" > </telerik:RadGridView> <telerik:RadDataPager Grid.Row="1" Grid.Column="0" x:Name="radDataPager" PageSize="50" AutoEllipsisMode="None" DisplayMode="First, Previous, Next, Text" Margin="10,0,10,0"/> <StackPanel Grid.Row="1" Grid.Column="0" Margin="5 5 5 5" HorizontalAlignment="Left" Orientation="Horizontal" Height="20" Width="Auto" VerticalAlignment="Center" > <telerik:RadButton x:Name="btAdd" Margin="5 0 5 0" Content="Dodaj" /> <telerik:RadButton x:Name="btEdit" Margin="5 0 5 0" Content="Edytuj" /> <telerik:RadButton x:Name="btDelete" Margin="5 0 5 0" Content="Usun" /> </StackPanel> <StackPanel Name="addFields" Background="LightGray" Visibility="Collapsed" VerticalAlignment="Top" Grid.Row="2" Grid.Column="0" Width="Auto" Height="Auto" Orientation="Horizontal"> <GroupBox Header="Szczegoly" Margin="2 2 2 2" > <Grid VerticalAlignment="Top" DataContext="{Binding SelectedItem, ElementName=grid}" Name="_gAddFields" Margin="0 0 0 0" Width="Auto" Height="Auto" > </Grid> </GroupBox> </StackPanel> <StackPanel Grid.Row="3" Grid.Column="0" Margin="5 5 5 5" HorizontalAlignment="Right" Orientation="Horizontal" Height="25" Width="Auto" VerticalAlignment="Center" > <telerik:RadButton x:Name="btSave" IsDefault="True" Width="60" Margin="5 0 5 0" Content="Zapisz" /> <telerik:RadButton x:Name="btOK" IsDefault="True" Width="60" Margin="5 0 5 0" Content="Akceptuj" /> <telerik:RadButton x:Name="btCancel" IsCancel="True" Width="60" Margin="5 0 5 0" Content="Anuluj" /> </StackPanel> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> Please help

  • Actionscript 3: Monitoring the activity level for multiple Microphones doesn't seem to work.

    - by Dave
    For a project I want to show all available webcams and microphones, so that the user can easily select whichever webcam/microphone combination they prefer. I run into an issue with the microphones listing though. Each microphone is listed with an activity animation and it's name. I am able to list all Microphones just fine (using the Microphone.names Array), but it seems like I can only get the activity viewer to work for one microphone. The other microphones show up with '-1' activity, which (as far as I know) is Flex for 'present, but not in use'. When unplugging the microphone that does show activity, the next one (in my case, the mic-in line on my motherboard) shows up with '0' activity (it's not connected, so that makes sense). During my testing I have a total of 3 microphones available, the not-connected onboard mic-in port, and two connected microphones. For testing purposes I use a timer that traces the current microphone activity each 100ms and the graph is also shown. It does not seem to matter what default microphone I set via flash' settings panel. The code I've only attached the revelant code snippets below to make it easier for you to read through them. Please let me know if you prefer the entire code. Main application.mxml Note: cont is a VBox. i is defined before this code snippet. var mics:Array = Microphone.names; for(i=0; i < mics.length; i++){ var mic:settingsMicEntry = new assets.settingsMicEntry; mic.d = {name: mics[i], index: i}; cont.addChild(mic); } assets/settingsMicEntry.mxml timer is defined before this code snippet. the SoundTransform is added to silence local microphone playback. Excluding this code does not solve the problem, sadly (I've tried). display is an MXML Canvas object. mic = Microphone.getMicrophone(d.index); if(mic){ // Temporary: The Microphones' visualizer var bar:Box = new Box(); bar.y = 50; bar.height = 0; bar.width = 66; bar.setStyle("backgroundColor", 0x003300); display.addChild(bar); var tf:SoundTransform = new SoundTransform(0); mic.setLoopBack(true); mic.soundTransform = tf; timer = new Timer(100); timer.addEventListener(TimerEvent.TIMER, function(e:TimerEvent):void{ var h:int = Math.floor((display.height/100)*mic.activityLevel); bar.height = (h>-1) ? h : 0; bar.y = (h>-1) ? display.height-h : display.height; trace('TIMER: '+h+' from '+d.name); }); timer.start(); } I'm pulling my hear out here, so any help is much appreciated! Thanks, -Dave Ps.: Pardon the messiness of the code!

  • Longitudinal Redundancy Check fails

    - by PaulH
    I have an application that decodes data from a magnetic stripe reader. But, I'm having difficulty getting my calculated LRC check byte to match the one on the cards. If I were to grab 3 cards each with 3 tracks, I would guess the algorithm below would work on 4 of the 9 tracks in those cards. The algorithm I'm using looks like this (C#): private static char GetLRC(string s, int start, int end) { int result = 0; for (int i = start; i <= end; i++) { result ^= Convert.ToByte(s[i]); } return Convert.ToChar(result); } This is an example of track 3 data that fails the check. On this card, track 2 matched, but track 1 also failed. 0 1 2 3 4 5 6 7 8 9 A B C D E F 00 3 4 4 4 4 4 4 4 4 4 4 5 5 5 5 5 10 5 5 5 5 5 6 6 6 6 6 6 6 6 6 6 7 20 7 7 7 7 7 7 7 7 7 8 8 8 8 8 8 8 30 8 8 8 9 9 9 9 9 9 9 9 9 9 0 0 0 40 0 0 0 0 0 0 0 1 2 3 4 1 1 1 1 1 50 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 60 3 3 3 3 3 3 3 3 The sector delimiter is ';' and it ends with a '?'. The LRC byte from this track is 0x30. Unfortunately, the algorithm above computes an LRC of 0x00 per the following calculation (apologies for its length. I want to be thorough): 00 ^ 3b = 3b ';' 3b ^ 33 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 31 = 39 39 ^ 32 = 0b 0b ^ 33 = 38 38 ^ 34 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 3f = 00 '?'

  • Setting value for autocomplete search field linked to Google Places API

    - by user1653350
    I have a web page where people will be able to enter multiple destinations. When they state they want to enter a new destination, the current field values are stored in arrays. If they choose to go back to a previous destination, the relevant values are reinserted into the form fields. I am using the search field linked to autocomplete as the visible display of the destination. When I attempt to put a value into the linked search field, the value is presented as if it is a placeholder instead of a value. Enter the field and the value is removed by the onFocus() event of the Google Places autocomplete add-in. How can I reinsert the value and have it recognised as a value instead of placeholder. field definition in the form <label for="GoogleDestSrch" class="inputText">Destination: <span id="DestinationDisplay2">1</span> <span class="required"><font size="5"> * </font></span></label> <input id="GoogleDestSrch" type="text" size="50" placeholder="Please enter your destination" /> initialise code for Google Places API listener var input = document.getElementById('GoogleDestSrch'); var autocomplete = new google.maps.places.Autocomplete(input); google.maps.event.addListener(autocomplete, 'place_changed', function() { fillInAddress(); }); attempting to reinsert value into search field when prior destination reloaded form.GoogleDestSrch.value = GoogleDestSrch[index]; Issue With Google Places <script language="JavaScript" type="text/javascript"> function GotoDestination(index) { var domove = true; if (index == 0) { index = lastIndex + 1; } else { if (index == -1) { index = lastIndex - 1; if (index == 0) { index = 1; domove = false; } } } if (domove) { if (index != lastIndex) { var doc = window.document; var pdbutton = doc.getElementById("pdbutton"); var pdbutton1 = doc.getElementById("pdbutton1"); if ((index > lastIndex)) { // move to next destination saveDataF(lastIndex); loadDataF(index); lastIndex = index; } else if (index <= lastIndex) { // move to previous destination saveDataF(lastIndex); loadDataF(index); lastIndex = index; } } } } var input; var autocomplete; // fill in the Google metadata when a destination is selected function fillInAddress() { var strFullValue = ''; var strFullGeoValue = ''; var place = autocomplete.getPlace(); document.getElementById("GoogleType").value = place.types[0]; } function saveDataF(index) { var fieldValue; var blankSearch = "Please enter"; // placeholder text for Google Places fieldValue = document.getElementById("GoogleDestSrch").value; if (fieldValue.indexOf(blankSearch) > -1) { fieldValue = ""; } GoogleDestSrch[index] = fieldValue; } function loadDataF(index) { if ((GoogleDestSrch[index] + "") == "undefined") { document.getElementById("GoogleDestSrch").value = ""; } else { document.getElementById("GoogleDestSrch").value = GoogleDestSrch[index]; } } // -- Destination: 1 * Type of place // input = document.getElementById('GoogleDestSrch'); autocomplete = new google.maps.places.Autocomplete(input); google.maps.event.addListener(autocomplete, 'place_changed', function () { fillInAddress(); }); //]]

  • .NET Programmatically invoke screenclick doesn't work?

    - by ropstah
    I'm trying to programmatically invoke an onclick event however the click is not received/handled. Am I missing something, or is security preventing the click to be executed?

  • How to group and sum values in XSLT

    - by johkar
    For each "agency" node I need to find the "stmt" elements that have the same key1, key2, key3 values and output just one "stmt" node with the "comm" and "prem" values summed together. For any "stmt" elements within that "agency" that don't match any other "stmt" elements based on key1, key2 and key3 I need to output them as is. So after transformation the first "agency" node would only have two "stmt" nodes (one summed) and the second "agency" node would be passed as is because the keys don't match. XSLT 1.0 or 2.0 solutions are ok...though my stylesheet is currently 1.0. Note that the agency nodes could have any number of "stmt" elements that have matching keys which need to be grouped and summed and any number that don't. <statement> <agency> <stmt> <key1>1234</key1> <key2>ABC</key2> <key3>15.000</key3> <comm>75.00</comm> <prem>100.00</prem> </stmt> <stmt> <key1>1234</key1> <key2>ABC</key2> <key3>15.000</key3> <comm>25.00</comm> <prem>200.00</prem> </stmt> <stmt> <key1>1234</key1> <key2>ABC</key2> <key3>17.50</key3> <comm>25.00</comm> <prem>100.00</prem> </stmt> </agency> <agency> <stmt> <key1>5678</key1> <key2>DEF</key2> <key3>15.000</key3> <comm>10.00</comm> <prem>20.00</prem> </stmt> <stmt> <key1>5678</key1> <key2>DEF</key2> <key3>17.000</key3> <comm>15.00</comm> <prem>12.00</prem> </stmt> </agency>

  • seg fault caused by malloc and sscanf in a function

    - by Framester
    Hi, I want to open a text file (see below), read the first int in every line and store it in an array, but I get an segmentation fault. I got rid of all gcc warnings, I read through several tutorials I found on the net and searched stackoverflow for solutions, but I could't make out, what I am doing wrong. It works when I have everything in the main function (see example 1), but not when I transfer it to second function (see example 2 further down). In example 2 I get, when I interpret gdb correctly a seg fault at sscanf (line,"%i",classes[i]);. I'm afraid, it could be something trivial, but I already wasted one day on it. Thanks in advance. [Example 1] Even though that works with everything in main: #include<stdio.h> #include<stdlib.h> #include<string.h> const int LENGTH = 1024; int main() { char *filename="somedatafile.txt"; int *classes; int lines; FILE *pfile = NULL; char line[LENGTH]; pfile=fopen(filename,"r"); int numlines=0; char *p; while(fgets(line,LENGTH,pfile)){ numlines++; } rewind(pfile); classes=(int *)malloc(numlines*sizeof(int)); if(classes == NULL){ printf("\nMemory error."); exit(1); } int i=0; while(fgets(line,LENGTH,pfile)){ printf("\n"); p = strtok (line," "); p = strtok (NULL, ", "); sscanf (line,"%i",&classes[i]); i++; } fclose(pfile); return 1; } [Example 2] This does not with the functionality transfered to a function: #include<stdio.h> #include<stdlib.h> #include<string.h> const int LENGTH = 1024; void read_data(int **classes,int *lines, char *filename){ FILE *pfile = NULL; char line[LENGTH]; pfile=fopen(filename,"r"); int numlines=0; char *p; while(fgets(line,LENGTH,pfile)){ numlines++; } rewind(pfile); * classes=(int *)malloc(numlines*sizeof(int)); if(*classes == NULL){ printf("\nMemory error."); exit(1); } int i=0; while(fgets(line,LENGTH,pfile)){ printf("\n"); p = strtok (line," "); p = strtok (NULL, ", "); sscanf (line,"%i",classes[i]); i++; } fclose(pfile); *lines=numlines; } int main() { char *filename="somedatafile.txt"; int *classes; int lines; read_data(&classes, &lines,filename) ; for(int i=0;i<lines;i++){ printf("\nclasses[i]=%i",classes[i]); } return 1; } [Content of somedatafile.txt] 50 21 77 0 28 0 27 48 22 2 55 0 92 0 0 26 36 92 56 4 53 0 82 0 52 -5 29 30 2 1 37 0 76 0 28 18 40 48 8 1 37 0 79 0 34 -26 43 46 2 1 85 0 88 -4 6 1 3 83 80 5 56 0 81 0 -4 11 25 86 62 4 55 -1 95 -3 54 -4 40 41 2 1 53 8 77 0 28 0 23 48 24 4 37 0 101 -7 28 0 64 73 8 1 ...

  • Play Video File in Asp. Net 3.5 in IIS

    I have developed an application to upload a video on the server and then play it. It runs well when i execute it in Visual Studio 2008 in-built web server.. But when I configure it on IIS, the video does not play... Is there any settings needed in IIS to play video ?? The code of Button Click event - **protected void btnPlayVideo_Click(object sender, EventArgs e) { try { string himaSagarURL = this.lnkbtnVideo.Text; bool isFullSize = false; this.Literal1.Text = this.Play_Video(himaSagarURL, isFullSize); } catch (Exception ex) { this.Response.Write(ex.ToString()); } } This button click event calls the Play_Video method which is given below.. The code I used for embedding - private string Play_Video(string sagarURL, bool isFullSize) { string himaSagarObject = ""; sagarURL = sagarURL + ""; sagarURL = sagarURL.Trim(); if (sagarURL.Length > 0) { //Continue. } else { throw new System.ArgumentNullException("sagarURL"); } string himaSagarWidthAndHeight = ""; if (isFullSize) { himaSagarWidthAndHeight = ""; } else { himaSagarWidthAndHeight = "width='640' height='480'"; } himaSagarObject = himaSagarObject + "<object classid='CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95' id='player' " + himaSagarWidthAndHeight + " standby='Please wait while the object is loaded...'>"; himaSagarObject = himaSagarObject + "<param name='url' value='" + sagarURL + "' />"; himaSagarObject = himaSagarObject + "<param name='src' value='" + sagarURL + "' />"; himaSagarObject = himaSagarObject + "<param name='AutoStart' value='true' />"; himaSagarObject = himaSagarObject + "<param name='Balance' value='0' />"; //-100 is fully left, 100 is fully right. himaSagarObject = himaSagarObject + "<param name='CurrentPosition' value='0' />"; //Position in seconds when starting. himaSagarObject = himaSagarObject + "<param name='showcontrols' value='true' />"; //Show play/stop/pause controls. himaSagarObject = himaSagarObject + "<param name='enablecontextmenu' value='true' />"; //Allow right-click. himaSagarObject = himaSagarObject + "<param name='fullscreen' value='" + isFullSize.ToString() + "' />"; //Start in full screen or not. himaSagarObject = himaSagarObject + "<param name='mute' value='false' />"; himaSagarObject = himaSagarObject + "<param name='PlayCount' value='1' />"; //Number of times the content will play. himaSagarObject = himaSagarObject + "<param name='rate' value='1.0' />"; //0.5=Slow, 1.0=Normal, 2.0=Fast himaSagarObject = himaSagarObject + "<param name='uimode' value='full' />"; // full, mini, custom, none, invisible himaSagarObject = himaSagarObject + "<param name='showdisplay' value='true' />"; //Show or hide the name of the file. himaSagarObject = himaSagarObject + "<param name='volume' value='50' />"; // 0=lowest, 100=highest himaSagarObject = himaSagarObject + "</object>"; return himaSagarObject; }**

  • [Flex 4 and .Net] Retrieving tables from SQL database

    Hi everyone, As the title says, I want to retrieve tables of data from a SQL database, using Flex 4 and .Net WebService. I'm new to both Flex and DotNet. Please tell me a proper way to do it.

  • php, mySQL & AJAX: Unable to use sessions across the scripts in the same domain

    - by Devner
    Hi all, I have the following pages: page1.php, page2.php and page3.php. Code in each of them is as below CODE: page1.php <script type="text/javascript"> $(function(){ $('#imgID').upload({ submit_to_url: "page2.php", file_name: 'myfile1', description : "Image", limit : 1, file_types : "*.jpg", }) }); </script> <body> <form action="page3.php" method="post" enctype="multipart/form-data" name="frm1" id="frm1"> //Some other text fields <input type="submit" name="submit" id="submit" value="Submit" /> </form> </body> page2.php <?php session_start(); $a = $_SESSION['a']; $b = $_SESSION['b']; $c = $_SESSION['c']; $res = mysql_query("SELECT col FROM table WHERE col1 = $a AND col2 = $b AND col3 = $c LIMIT 1"); $num_rows = mysql_num_rows($res); echo $num_rows; //echos 0 when in fact it should have been 1 because the data in the Session exists. //Ok let's proceed further //... Do some stuff... //Store some more values and create new session variables (and assume that page1.php is going to be able to use it) $_SESSION['d'] = 'd'; $_SESSION['e'] = 'e'; $_SESSION['f'] = 'f'; if (move_uploaded_file($_FILES['file']['tmp_name'], $file)) { echo "success"; } else { echo "error ".$_FILES['file']['error']; } ?> page3.php <?php session_start(); if( isset($_POST['submit']) ) { //These sessions are non-existent although the AJAX request //to page2.php may have created them when called via AJAX from within page1.php echo $_SESSION['d'].$_SESSION['e'].$_SESSION['f']; ?> } ?> As the code says it I am posting some info via AJAX call from page1.php to page2.php. page2.php is supposed to be able to use the session values from page1.php i.e. $_SESSION['a'], $_SESSION['b'] and $_SESSION['c'] but it does not. Why? How can I fix this? page2.php is creating some more sessions after some processing is done and a response is sent back to page1.php. The submit button of the form on page1.php is hit and the page gets POST'ed to page3.php. But when the SESSION info that gets created in page2.php is echoed, it's blank signifying that SESSIONS from page2.php are not used. How can I fix this? I looked over a lot of information and have spent about 50 hours trying to do different things with my scripts before arriving at the above conclusions. My app. is custom made using function (not OOPS) and does not use any PHP frameworks & I am not even about to use any as my knowledge of OOP concepts is limited any many frameworks are object oriented. I came across race conditions, but the solutions provided don't help too much. One more solution of using DB to hold sessions and seek and retrieve from DB is the last thing on my mind and I really want to avoid creating table, coding and maintaining code for a task as simple as just keeping sessions across pages in the same domain. So my request is: Is there a way that I can solve the above problem(s) via simple coding in present conditions? Any help is appreciated. Thank you.

  • pass data from popup to parent

    - by user522962
    I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that? Here's my parent: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" backgroundColor="green" width="50%" height="100%" xmlns:local="*" > <fx:Script> <![CDATA[ import pup; import mx.managers.PopUpManager; public function showPup(evt:MouseEvent):void { var ttlWndw:pup = PopUpManager.createPopUp(this, pup, true) as pup; PopUpManager.centerPopUp(ttlWndw); } ]]> </fx:Script> <mx:VBox> <local:pup id="pupLove" visible="false" includeInLayout="false" /> <s:Button click="showPup(event);" label="launch Pup" /> <mx:Text id="Ptest" color="black" text="from Parent:{pupLove.dg.length}" /> </mx:VBox> </s:Application> And a popup child called 'pup.mxml': <?xml version="1.0" encoding="utf-8"?> <s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"> <fx:Script> <![CDATA[ public function init():void{ // send php call } import mx.events.CloseEvent; import mx.managers.PopUpManager; private function removePup(evt:Event):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <s:ArrayCollection id="dg"> </s:ArrayCollection> </fx:Declarations> <s:TitleWindow width="100%" height="100%" close="removePup(event)"> <mx:VBox> <mx:Text id="test" color="red" text="from Child:{dg.length}" /> <s:Button label="add Items" click="dg.addItem({id:'cat'})" /> </mx:VBox> </s:TitleWindow> </s:Group> UPDATE: I guess my question can be more easily stated as: "is there a way to call a child's function from the parent without actually loading the child?"

Here is my current code, but I feel I've done it wrong. import java.awt.BasicStroke; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.LinearGradientPaint; import java.awt.Polygon; import java.awt.Stroke; import java.awt.geom.Point2D; import java.awt.geom.Rectangle2D; import javax.swing.JFrame; import javax.swing.JPanel; public class meter extends JFrame { Stroke drawingStroke = new BasicStroke(2); Rectangle2D rect = new Rectangle2D.Double(105, 50, 40, 200); Double meterPercent = new Double(0.57); public meter() { setTitle("Meter"); setLayout(null); setSize(300, 300); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); } public void paint(Graphics g) { // Paint Meter Graphics2D g1 = (Graphics2D) g; g1.setStroke(drawingStroke); g1.draw(rect); // Set Meter Colors Point2D start = new Point2D.Float(0, 0); Point2D end = new Point2D.Float(0, this.getHeight()); float[] dist = { 0.1f, 0.5f, 0.9f }; Color[] colors = { Color.green, Color.yellow, Color.red }; LinearGradientPaint p = new LinearGradientPaint(start, end, dist, colors); g1.setPaint(p); g1.fill(rect); // Make a triangle - Arrow on Meter int[] x = new int[3]; int[] y = new int[3]; int n; // count of points // Set Points for Arrow Integer meterArrowHypotenuse = (int) rect.getX(); Integer meterArrowTip = (int) rect.getY() + (int) (rect.getHeight() * (1 - meterPercent)); x[0] = meterArrowHypotenuse - 25; x[1] = meterArrowHypotenuse - 25; x[2] = meterArrowHypotenuse - 5; y[0] = meterArrowTip - 20; // Top Left y[1] = meterArrowTip + 20; // Bottom Left y[2] = meterArrowTip; // Tip of Arrow n = 3; // Number of points, 3 because its a triangle // Draw Arrow Border Polygon myTriShadow = new Polygon(x, y, n); // a triangle g1.setPaint(Color.black); g1.fill(myTriShadow); // Set Points for Arrow Board x[0] = x[0] + 1; x[1] = x[1] + 1; x[2] = x[2] - 2; y[0] = y[0] + 3; y[1] = y[1] - 3; y[2] = y[2]; Robot robot = new Robot(); Color colorMeter = robot.getPixelColor(x[2]+10, y[2]); // Draw Arrow Polygon myTri = new Polygon(x, y, n); // a triangle Color colr = new Color(colorMeter.getRed(), colorMeter.getGreen(), colorMeter.getBlue()); g1.setPaint(colr); g1.fill(myTri); } public static void main(String[] args) { new meter(); } } Thanks for looking.
