• Magento table rates custom options

  - by Usman Ahmad

  in Tablerate.php I want to change the calculation. So for some Products with custom options like width, height the shipping cost must change. I tried with this method to find out if one product in cart has width or height greater than 60cm (example). But currently I have no Idea how to get custom option values... this code working well. foreach ($request->getAllItems() as $item) { echo 'Name: '.$item->getName(). '<br/> SKU:'.$item->getSku(). '<br/> ProductID: '.$item->getProductId(). '<br/> Price: '.$item->getPrice().'<br/>'; } Thanks

• convert array of objects to concatenated string

  - by oo

  if i have: List<Car> where car is: public class Car { public int Year; public string Name; } and i want to take this array and create a concatenated string by "," so it would return: "Toyota", "Ford", "Chevy" i can do it manually like this: private static string CreateConcatenatedList(List<Car> parts_) { StringBuilder b = new StringBuilder(); foreach (Car bp in parts_) { b.Append(bp.Name + ", "); } b.Remove(b.Length - 2, 2); return b.ToString(); } but i thought there might be a more elegant way

• A 'do' statement at the end of my perl script never runs

  - by Jeremy Petzold

  In my main script, I am doing some archive manipulation. Once I have completed that, I want to run a separate script to upload my archives to and FTP server. Separately, these scripts work well. I want to add the FTP script to the end of my archive script so I only need to worry about scheduling one script to run and I want to guarantee that the first script completes it work before the FTP script is called. After looking at all the different methods to call my FTP script, I settled on 'do', however, when my do statement is at the end of the script, it never runs. When I place it in my main foreach loop, it runs fine, but it runs multiple times which I want to avoid since the FTP script can handle having multiple archives to upload. Is there something I am missing? Why does it not run? Thanks

• initializing properties with private sets in .Net

  - by Martin Neal

  public class Foo { public string Name { get; private set;} // <-- Because set is private, } void Main() { var bar = new Foo {Name = "baz"}; // <-- This doesn't compile /*The property or indexer 'UserQuery.Foo.Name' cannot be used in this context because the set accessor is inaccessible*/ using (DataContext dc = new DataContext(Connection)) { // yet the following line works. **How**? IEnumerable<Foo> qux = dc.ExecuteQuery<Foo>( "SELECT Name FROM Customer"); } foreach (q in qux) Console.WriteLine(q); } I have just been using the private modifier because it works and kept me from being stupid with my code, but now that I need to create a new Foo, I've just removed the private modifier from my property. I'm just really curious, why does the ExecuteQuery into an IEnumerable of Foo's work?

• using session library in CodeIgniter

  - by marcin_koss

  For some reason I'm heaving a tough time understanding how sessions in CI work. I would like to change the following part of the code to use CodeIgniter sessions rather than the way it's normally done in PHP. What would be the best way to do it? foreach($_POST['qty'] as $k = $v) { $id = (int)$k; $qty = (int)$v; $_SESSION['cart'][$id]['quantity'] = $qty; } Another question! While using CI session library, when a session has multidimensional structure, do I always have to drop session's content to an array first, before I can read the values I need?

• c#, can you think of anymore optimization in this code?

  - by Sha Le

  Hi All: Look at the following code: StringBuilder row = TemplateManager.GetRow("xyz"); // no control over this method StringBuilder rows = new StringBuilder(); foreach(Record r in records) { StringBuilder thisRow = new StringBuilder(row.ToString()); thisRow.Replace("%firstName%", r.FirstName) .Replace("%lastName%", r.LastName) // all other replacement goes here .Replace("%LastModifiedDate%", r.LastModifiedDate); //finally append row to rows rows.Append(thisRow); } Currently 3 StringBuilders and row.ToString() is inside a loop. Is there any room for further optimization here? Thanks a bunch. :-)

• How to save an image in it's original format?

  - by Patrick Klug

  I am trying to figure out how I can get the original format of an image so that I can store it with the same encoding. It seems that the only way to save an Image is by using a BitmapEncoder but I don't know how I can get the correct format from the image. Example: Clipboard.GetImage() returns a InteropBitmap which doesn't seem to contain any information about the original format. I also tried using an Extension method: public static void Save(this BitmapImage image, System.IO.Stream stream) { var decoder = BitmapDecoder.Create(image.StreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); var encoder = BitmapEncoder.Create(decoder.CodecInfo.ContainerFormat); foreach (var frame in decoder.Frames) { encoder.Frames.Add(BitmapFrame.Create(decoder.Frames[0])); } encoder.Save(stream); } but the problem is that a) the ImageSource is not always a BitmapImage (Clipboard.GetImage()) for example and b) the image.StreamSource can be null in some cases (seems to be when the image is loaded via a relative Uri)

• Calling this[int index] via reflection

  - by tkutter

  I try to implement a reflection-based late-bound library to Microsoft Office. The properties and methods of the Offce COM objects are called the following way: Type type = Type.GetTypeFromProgID("Word.Application"); object comObject = Activator.CreateInstance(type); type.InvokeMember(<METHOD NAME>, <BINDING FLAGS>, null, comObject, new object[] { <PARAMS>}); InvokeMember is the only possible way because Type.GetMethod / GetProperty works improperly with the COM objects. Methods and properties can be called using InvokeMember but now I have to solve the following problem: Method in the office-interop wrapper: Excel.Workbooks wb = excel.Workbooks; Excel.Workbook firstWb = wb[0]; respectively foreach(Excel.Workbook w in excel.Workbooks) // doSmth. How can I call the this[int index] operator of Excel.Workbooks via reflection?

• Modulus PHP Problem

  - by Eli

  I have a problem, I am trying to calculate what the lowest prime is of a number but I do not understand the result that PHP is giving me. If I have this number $number = 600851475143; Then I modulus it: $primes = array( 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97); foreach($primes as $key=>$value) { if($number % $value == 0 ) {echo $value; break; } } Why is it that $value = 3? If $value = 3, that means that 600851475143 / 3 should be an integer, but its not. So I do not understand why that if() evaluates to true?
