• Send mail to multiple recipient

  - by Ahmad Maslan

  Hi, i have already research on using the mail() to send to multiple recipient's but i just cant get it to work. What im trying to do is, for every order that i have, order 1,2,3, each having their own email addresses, when i change their order status from pending to confirm, the mail() will use that id to refer to the db table and send the email of those 3 orders. But for my case, it mailed just the latest order which is order 3. This is the form that i use to change the order status. <form action="results-action" method="post" enctype="multipart/form-data"> <fieldset> <table id ="table_id" class="display"> <thead> <tr><td><h2>Pending Order</h2></td></tr> <tr> <th scope="col">Order ID</th> <th scope="col"> </th> <th scope="col">Name</th> <th scope="col">Address</th> <th scope="col">Product Name</th> <th scope="col">Produt Quantity</th> <th scope="col">Price</th> <th scope="col">Order status</th> </tr> </thead> <tbody> <?php while ($row = mysqli_fetch_array($result)) { ?> <tr> <td><input type="text" value='<?=$row['virtuemart_order_id']?>' name="orderid" id="virtuemart_order_id"></td> <td><input type="hidden" value='<?=$row['virtuemart_product_id']?>' name="productid" id="virtuemart_product_id"></td> <td><?=$row['first_name']?></td> <td><?=$row['address_1']?></td> <td><?=$row['order_item_name']?></td> <td><?=$row['product_quantity']?></td> <td><?=$row['product_final_price'] ?></td> <td><select name='change[<?=$row['virtuemart_order_id']?>]'> <option value='C'> Confirmed</option> <option value='X'> Cancelled</option></select></td> </tr> <?php } ?> </tbody> </table> </fieldset> <fieldset> <table> <tr> <td><input type="submit" value="Update status" name="update status"> </td> </tr> </table> </fieldset> </form> This is the php, using the order id from the form to select the email addresses. <?php $orderid = $_POST['orderid']; // build SQL statement to select email addresses $query3 = "SELECT email from ruj3d_virtuemart_order_userinfos where virtuemart_order_id = '$orderid'"; // execute SQL statement $result3 = mysqli_query($link, $query3) or die(mysqli_error($link)); $subject = "Order confirmed by Home and decor"; $message = "Hello! This is a message to inform that your order has been confirmed"; $from = "[email protected]"; $headers = "From: $from"; while($row3 = mysqli_fetch_array($result3)){ $addresses[] = $row3['email']; } $to = implode(",", $addresses); mail($to, $subject, $message, $headers); ?>

• Error "Input length must be multiple of 8 when decrypting with padded cipher"

• Issue with Multiple ModalPopups, ValidationSummary and UpdatePanels

  - by Aaron Hoffman

  I am having an issue when a page contains multiple ModalPopups each containing a ValidationSummary Control. Here is the functionality I need: A user clicks a button and a Modal Popup appears with dynamic content based on the button that was clicked. (This functionality is working. Buttons are wrapped in UpdatePanels and the partial page postback calls .Show() on the ModalPopup) "Save" button in ModalPopup causes client side validation, then causes a full page postback so the entire ModalPopup disappears. (ModalPopup could disappear another way - the ModalPopup just needs to disappear after a successful save operation) If errors occur in the codebehind during Save operation, messages are added to the ValidationSummary (contained within the ModalPopup) and the ModalPopup is displayed again. When the ValidationSummary's are added to the PopupPanel's, the ModalPopups no longer display correctly after a full page postback caused by the "Save" button within the second PopupPanel. (the first panel continues to function correctly) Both PopupPanels are displayed, and neither is "Popped-Up", they are displayed in-line. Any ideas on how to solve this?

• Questions related to writing your own file downloader using multiple threads java

  - by Shekhar

  Hello In my current company, i am doing a PoC on how we can write a file downloader utility. We have to use socket programming(TCP/IP) for downloading the files. One of the requirements of the client is that a file(which will be large in size) should be transfered in chunks for example if we have a file of 5Mb size then we can have 5 threads which transfer 1 Mb each. I have written a small application which downloads a file. You can download the eclipe project from http://www.fileflyer.com/view/QM1JSC0 A brief explanation of my classes FileSender.java This class provides the bytes of file. It has a method called sendBytesOfFile(long start,long end, long sequenceNo) which gives the number of bytes. import java.io.File; import java.io.IOException; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileSender { private static final String FILE_NAME = "C:\\shared\\test.pdf"; public ByteArrayWrapper sendBytesOfFile(long start,long end, long sequenceNo){ try { File file = new File(FILE_NAME); byte[] fileBytes = FileUtils.readFileToByteArray(file); System.out.println("Size of file is " +fileBytes.length); System.out.println(); System.out.println("Start "+start +" end "+end); byte[] bytes = getByteArray(fileBytes, start, end); ByteArrayWrapper wrapper = new ByteArrayWrapper(bytes, sequenceNo); return wrapper; } catch (IOException e) { throw new RuntimeException(e); } } private byte[] getByteArray(byte[] bytes, long start, long end){ long arrayLength = end-start; System.out.println("Start : "+start +" end : "+end + " Arraylength : "+arrayLength +" length of source array : "+bytes.length); byte[] arr = new byte[(int)arrayLength]; for(int i = (int)start, j =0; i < end;i++,j++){ arr[j] = bytes[i]; } return arr; } public static long fileSize(){ File file = new File(FILE_NAME); return file.length(); } } Second Class is FileReceiver.java - This class receives the file. Small Explanation what this file does This class finds the size of the file to be fetched from Sender Depending upon the size of the file it finds the start and end position till the bytes needs to be read. It starts n number of threads giving each thread start,end, sequence number and a list which all the threads share. Each thread reads the number of bytes and creates a ByteArrayWrapper. ByteArrayWrapper objects are added to the list Then i have while loop which basically make sure that all threads have done their work finally it sorts the list based on the sequence number. then the bytes are joined, and a complete byte array is formed which is converted to a file. Code of File Receiver package com.filedownloader; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileReceiver { public static void main(String[] args) { FileReceiver receiver = new FileReceiver(); receiver.receiveFile(); } public void receiveFile(){ long startTime = System.currentTimeMillis(); long numberOfThreads = 10; long filesize = FileSender.fileSize(); System.out.println("File size received "+filesize); long start = filesize/numberOfThreads; List<ByteArrayWrapper> list = new ArrayList<ByteArrayWrapper>(); for(long threadCount =0; threadCount<numberOfThreads ;threadCount++){ FileDownloaderTask task = new FileDownloaderTask(threadCount*start,(threadCount+1)*start,threadCount,list); new Thread(task).start(); } while(list.size() != numberOfThreads){ // this is done so that all the threads should complete their work before processing further. //System.out.println("Waiting for threads to complete. List size "+list.size()); } if(list.size() == numberOfThreads){ System.out.println("All bytes received "+list); Collections.sort(list, new Comparator<ByteArrayWrapper>() { @Override public int compare(ByteArrayWrapper o1, ByteArrayWrapper o2) { long sequence1 = o1.getSequence(); long sequence2 = o2.getSequence(); if(sequence1 < sequence2){ return -1; }else if(sequence1 > sequence2){ return 1; } else{ return 0; } } }); byte[] totalBytes = list.get(0).getBytes(); byte[] firstArr = null; byte[] secondArr = null; for(int i = 1;i<list.size();i++){ firstArr = totalBytes; secondArr = list.get(i).getBytes(); totalBytes = concat(firstArr, secondArr); } System.out.println(totalBytes.length); convertToFile(totalBytes,"c:\\tmp\\test.pdf"); long endTime = System.currentTimeMillis(); System.out.println("Total time taken with "+numberOfThreads +" threads is "+(endTime-startTime)+" ms" ); } } private byte[] concat(byte[] A, byte[] B) { byte[] C= new byte[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; } private void convertToFile(byte[] totalBytes,String name) { try { FileUtils.writeByteArrayToFile(new File(name), totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } Code of ByteArrayWrapper package com.filedownloader; import java.io.Serializable; public class ByteArrayWrapper implements Serializable{ private static final long serialVersionUID = 3499562855188457886L; private byte[] bytes; private long sequence; public ByteArrayWrapper(byte[] bytes, long sequenceNo) { this.bytes = bytes; this.sequence = sequenceNo; } public byte[] getBytes() { return bytes; } public long getSequence() { return sequence; } } Code of FileDownloaderTask import java.util.List; public class FileDownloaderTask implements Runnable { private List<ByteArrayWrapper> list; private long start; private long end; private long sequenceNo; public FileDownloaderTask(long start,long end,long sequenceNo,List<ByteArrayWrapper> list) { this.list = list; this.start = start; this.end = end; this.sequenceNo = sequenceNo; } @Override public void run() { ByteArrayWrapper wrapper = new FileSender().sendBytesOfFile(start, end, sequenceNo); list.add(wrapper); } } Questions related to this code 1) Does file downloading becomes fast when multiple threads is used? In this code i am not able to see the benefit. 2) How should i decide how many threads should i create ? 3) Are their any opensource libraries which does that 4) The file which file receiver receives is valid and not corrupted but checksum (i used FileUtils of common-io) does not match. Whats the problem? 5) This code gives out of memory when used with large file(above 100 Mb) i.e. because byte array which is created. How can i avoid? I know this is a very bad code but i have to write this in one day -:). Please suggest any other good way to do this? Thanks Shekhar

• Search multiple datepicker on same grid

  - by DHF

  I'm using multiple datepicker on same grid and I face the problem to get a proper result. I used 3 datepicker in 1 grid. Only the first datepicker (Order Date)is able to output proper result while the other 2 datepicker (Start Date & End Date) are not able to generate proper result.

• Do any CDN services offer multiple urls (or aliases) for your files?

  - by Jakobud

  Lets say a company has multiple commercial web properties that happen to use a lot of the same images on each site. For SEO reasons, the sites must not appear to be related to eachother in any way. This means that the sites can't all link to the same image, even though they all use the same one. Therefore, an image is uploaded to each site and served from each site separately. In order to improve maintainability and latency, lets say the company wanted to use a CDN service. What I'm wondering is, if you upload a file, like an image or something, to a CDN, is there basically one single URL that you access that image at? Or do some (or all) CDN services offer alias URLs so that you can access the same resource from multiple URLs? Example of undesirable situation: Both sites link to the same file URL Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Example of DESIRABLE situation: Both sites link to the same file via different URLs Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-alias-path/myimage.jpg"/> So in the end, there is only one single file, myimage.jpg on the CDN server, but it is accessible from multiple URLs. Is this possible with CDN services? I know this would make browsers cache the same image twice, but at least it would be better for maintainability. Only one file would ever have to be uploaded.

• Linq to Datarow, Select multiple columns as distinct?

  - by Beta033

  basically i'm trying to reproduce the following mssql query as LINQ SELECT DISTINCT [TABLENAME], [COLUMNNAME] FROM [DATATABLE] the closest i've got is Dim query = (From row As DataRow In ds.Tables("DATATABLE").Rows _ Select row("COLUMNNAME") ,row("TABLENAME").Distinct when i do the above i get the error Range variable name can be inferred only from a simple or qualified name with no arguments. i was sort of expecting it to return a collection that i could then iterate through and perform actions for each entry. maybe a datarow collection? As a complete LINQ newb, i'm not sure what i'm missing. i've tried variations on Select new with { row("COLUMNNAME") ,row("TABLENAME")} and get: Anonymous type member name can be inferred only from a simple or qualified name with no arguments. Also, does anyone know of any good books/resources to get fluent?

• Using JQuery to replace multiple instances of HTML on one page

  - by Kenneth B

  I've made a script which copies the alt attribute of an image and puts it into a <span>. It also formulates the information divided by a hyphen. It works like a charm, but only with one image. I would also like to wrap a <div> around the image to prevent unnecessary markup. Script snippets: HTML: <div id="hoejre"> <p> <span class="alignright"> <img src="tommy_stor.jpg" alt="Name - Title" width="162" height="219" /> <span></span> </span> </p> </div> jQuery: var alt = $("#hoejre p span img").attr("alt"); $('#hoejre p span span') .html("<strong>" + alt.replace("-", "</strong> <em>") + "</em>"); Output: <span class="alignright"> <img height="219" width="162" alt="Name - Title" src="tommy_stor.jpg"> <span> <strong>Name</strong><em>Title</em> </span> </span> How do you I repeat the effect on several images, with different information within?

• Find multiple regex in each line and skip result if one of the regex doesn't match

  - by williamx

  I have a list of variables: variables = ['VariableA', 'VariableB','VariableC'] which I'm going to search for, line by line ifile = open("temp.txt",'r') d = {} match = zeros(len(variables)) for line in ifile: emptyCells=0 for i in range(len(variables)): regex = r'('+variables[i]+r')[:|=|\(](-?\d+(?:\.\d+)?)(?:\))?' pattern_variable = re.compile(regex) match[i] = re.findall(pattern_variable, line) if match[j] == []: emptyCells = emptyCells+1 if emptyCells == 0: for k, v in match[j]: d.setdefault(k, []).append(v) The requirement is that I will only keep the lines where all the regex'es matches! I want to collect all results for each variable in a dictionary where the variable name is the key, and the value becomes a list of all matches. The code provided is only what I've found out so far, and is not working perfectly yet...

• Multiple Exception Handlers for one exception type

  - by danish

  I am using Enterprose Library 4.1. I have created a custom exception handler called CustomHandler. This is how the configuration section would look like: <exceptionHandling> <exceptionPolicies> <add name="Exception Policy"> <exceptionTypes> <add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" postHandlingAction="NotifyRethrow" name="Exception"> <exceptionHandlers> <add type="WindowsFormsApplication1.CustomHandler, WindowsFormsApplication1" name="Custom Handler" /> <add exceptionMessage="Some test mesage." exceptionMessageResourceName="" exceptionMessageResourceType="" replaceExceptionType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionHandlingException, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ReplaceHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling" name="Replace Handler" /> </exceptionHandlers> </add> </exceptionTypes> </add> </exceptionPolicies> </exceptionHandling> There are two handlers for same exception type. What I want is that based on a certain condition one of the handlers should handle the exception. Any ideas how that can be done? Is there a way to call the other handler from inside the HandleException method of the custom handler based on some condition?

• Delphi Exception handling problem with multiple Exception handling blocks

  - by Robert Oschler

  I'm using Delphi Pro 6 on Windows XP with FastMM 4.92 and the JEDI JVCL 3.0. Given the code below, I'm having the following problem: only the first exception handling block gets a valid instance of E. The other blocks match properly with the class of the Exception being raised, but E is unassigned (nil). For example, given the current order of the exception handling blocks when I raise an E1 the block for E1 matches and E is a valid object instance. However, if I try to raise an E2, that block does match, but E is unassigned (nil). If I move the E2 catching block to the top of the ordering and raise an E1, then when the E1 block matches E is is now unassigned. With this new ordering if I raise an E2, E is properly assigned when it wasn't when the E2 block was not the first block in the ordering. Note I tried this case with a bare-bones project consisting of just a single Delphi form. Am I doing something really silly here or is something really wrong? Thanks, Robert type E1 = class(EAbort) end; E2 = class(EAbort) end; procedure TForm1.Button1Click(Sender: TObject); begin try raise E1.Create('hello'); except On E: E1 do begin OutputDebugString('E1'); end; On E: E2 do begin OutputDebugString('E2'); end; On E: Exception do begin OutputDebugString('E(all)'); end; end; // try() end;

• Attempting to update multiple partial views from a single Ajax.ActionLink

  - by mwright

  I have a a partial view which contains other partial views. I am trying to the main partial view ( "MainPartialView" ) from an Ajax.ActionLink in a partial view contained by the main partial view ( "DetailsView" ). Everything appears to be called just fine and I can step through and it executes all of the code on the pages. However, after that is all done it throws this error in a popup box in visual studio: htmlfile: Unknown runtime error This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632.

• How do I delete multiple rows in Entity Framework (without foreach)

  - by Jon Galloway

  I'm deleting several items from a table using Entity Framework. There isn't a foreign key / parent object so I can't handle this with OnDeleteCascade. Right now I'm doing this: var widgets = context.Widgets .Where(w => w.WidgetId == widgetId); foreach (Widget widget in widgets) { context.Widgets.DeleteObject(widget); } context.SaveChanges(); It works but the foreach bugs me. I'm using EF4 but I don't want to execute SQL. I just want to make sure I'm not missing anything - this is as good as it gets, right? I can abstract it with an extension method or helper, but somewhere we're still going to be doing a foreach, right?

• How to use multiple DisplayName attribute using Entity Framework and ASP.Net Mvc 2

  - by Picflight

  Depending on where I use my Class, I want to be able to show a different DisplayName. I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

• jQuery validation per multiple fieldsets, how to use different event to trigger validation per secti

  - by Jesse

  Hi All! I have a really, really long form (about 300 fields) that I broke down into different sections using this slick jQuery plugin Form Wizard. If you group your form into different fieldsets, the FormWizard will automagically display one section at a time, with a Next hyperlink to take you to the next section: <a id="step0Next" class="next" href="#">Next ></a> My question is this: Using the jQuery Validation plugin, how can I validate each fieldset when a user clicks Next, and so forth, instead of using the Submit button. Put differently, how can I change the trigger event from Submit to six different hyperlinks for six separate sections? Thanks for helping this newb out.

• Linq where clause with multiple conditions and null check

  - by SocialAddict

  I'm trying to check if a date is not null in linq and if it isn't check its a past date. QuestionnaireRepo.FindAll(q => !q.ExpiredDate.HasValue || q.ExpiredDate >DateTime.Now).OrderByDescending(order => order.CreatedDate); I need the second check to only apply if the first is true. I am using a single repository pattern and FindAll accepted a where clause ANy ideas? There are lots of similar questions on here but not that give the answer, I'm very new to Linq as you may of guessed :) Edit: I get the results I require now but it will be checking the conditional on null values in some cases. Is this not a bad thing?

• Hierarchical templating multiple object types in silverlight

  - by Dan Wray

  Is it possible and if so what is the best way to implement the following hierarchical structure in a silverlight (4) TreeView control? (where Item and Group are classes which can exist in the tree). Group | |-Item | |-Group | | | |-Item | | | |-Item | |-Item The structure could of course be arbitrarily more complex than this, if needed. HierarchicalDataTemplates appear to be the way to approach this, but I'm specifically having trouble understanding how I might apply the template to interpret the different classes correctly. A similar question was asked for WPF, the answer for which made use of the TargetType property on the HierarchicalDataTemplate, but I am uncertain whether that property is available in the silverlight version since I don't appear to have access to it in my environment.

• Multiple ToggleButton image with different highlight image in WPF

  - by Ryan

  I am very new to WPF and needed some pointers as to why this is not working correctly. I am trying to make a maximize button that will change to a restore button when clicked. I thought a toggle button with 2 different styles that would be changed in the code behind could work. I am first trying to get the maximize button working and have ran into a problem. I get the error 'System.Windows.Controls.Image' is not a valid value for the 'System.Windows.Controls.Image.Source' property on a Setter. in my xaml. I seem to be not understanding something completely. Any help would be most helpful :) Ryan <Style x:Key="Maximize" TargetType="{x:Type ToggleButton}"> <Style.Resources> <Image x:Key="MaxButtonImg" Source="/Project;component/Images/maxbutton.png" /> <Image x:Key="MaxButtonHighlight" Source="/Project;component/Images/maxbutton-highlight.png" /> </Style.Resources> <Setter Property="ContentTemplate"> <Setter.Value> <Image> <Image.Style> <Style TargetType="{x:Type Image}"> <Setter Property="Source" Value="{DynamicResource MaxButtonImg}"/> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Source" Value="{DynamicResource MaxButtonHighlight}"/> </Trigger> </Style.Triggers> </Style> </Image.Style> </Image> </Setter.Value> </Setter> </Style> <ToggleButton Name="MaxButton" Width="31" Height="31" BorderThickness="0" Click="MaxButton_Click" Margin="0,0,10,0" Tag="Max" Style="{DynamicResource Maximize}" /> My code behind would do something simple like this: private void MaxButton_Click(object sender, RoutedEventArgs e) { ToggleButton tg = (ToggleButton)sender; if ( tg.IsChecked == true) { tg.Style = (Style)FindResource("Restore"); this.WindowState = WindowState.Maximized; } else { tg.Style = (Style)FindResource("Maximize"); this.WindowState = WindowState.Normal; } }
