  • StructureMap - Injecting a dependency into a base class?

    - by David
    In my domain I have a handful of "processor" classes which hold the bulk of the business logic. Using StructureMap with default conventions, I inject repositories into those classes for their various IO (databases, file system, etc.). For example: public interface IHelloWorldProcessor { string HelloWorld(); } public class HelloWorldProcessor : IHelloWorldProcessor { private IDBRepository _dbRepository; public HelloWorldProcessor(IDBRepository dbRepository) { _dbRepository = dbrepository; } public string HelloWorld(){ return _dbRepository.GetHelloWorld(); } } Now, there are some repositories that I'd like to be available to all processors, so I made a base class like this: public class BaseProcessor { protected ICommonRepository _commonRepository; public BaseProcessor(ICommonRepository commonRepository) { _commonRepository = commonRepository; } } But when my other processors inherit from it, I get a compiler error on each one saying that there's no constructor for BaseProcessor which takes zero arguments. Is there a way to do what I'm trying to do here? That is, to have common dependencies injected into a base class that my other classes can use without having to write the injections into each one?

  • Warning as Error - How to rid these

    - by coffeeaddict
    I cannot figure out how to get rid of errors that basically should not be halting my compile in VS 2010 and should not be show stoppers, or at least I will fix them later but I don't want the compile to just error and halt on these kinds of problems. For example I'm getting the following error: Error 1 Warning as Error: XML comment on 'ScrewTurn.Wiki.SearchEngine.Relevance.Finalize(float)' has a paramref tag for 'IsFinalized', but there is no parameter by that name C:\www\Wiki\Screwturn3_0_2_509\SearchEngine\Relevance.cs 60 70 SearchEngine for this code: /// /// Normalizes the relevance after finalization. /// /// The normalization factor. /// If is false ( was not called). public void NormalizeAfterFinalization(float factor) { if(factor < 0) throw new ArgumentOutOfRangeException("factor", "Factor must be greater than or equal to zero"); if(!isFinalized) throw new InvalidOperationException("Normalization can be performed only after finalization"); value = value * factor; } I looked in Tools | Options and I don't see where I can tweak the compiler and tell it not to worry about comment or XHTML based errors.

  • Why doesn't ConcurrentQueue<T>.Count return 0 when IsEmpty == true?

    - by DanTup - Danny Tuppeny
    I was reading about the new concurrent collection classes in .NET 4 on James Michael Hare's blog, and the page talking about ConcurrentQueue<T> says: It’s still recommended, however, that for empty checks you call IsEmpty instead of comparing Count to zero. I'm curious - if there is a reason to use IsEmpty instead of comparing Count to 0, why does the class not internally check IsEmpty and return 0 before doing any of the expensive work to count? E.g.: public int Count { get { // Check IsEmpty so we can bail out quicker if (this.IsEmpty) return 0; // Rest of "expensive" counting code } } It seems strange to suggest this if it could be "fixed" so easily with no side-effects?

  • How much space do NTFS hardlinks/symlinks occupy?

    - by Felix Dombek
    Well, I guess it must be something proportional to the original filename plus the new filename for symlinks, and only the new filename for hardlinks, but how does this affect the disk space exactly? I just made a folder with about a hundred thousand symbolic links in it, and the folder still reported 0 bytes usage. I may be mistaken, but I even think the free capacity of the drive remained the same. Then I permanently deleted the folder and the sizes still stayed the same. Could I fill up a hard disk just with symlinks? Or does NTFS have limitations in that no more than x symlinks are allowed on one drive/in one folder, so the capacity of the drive cannot be reached?

  • Problem with averaging corrupted images to eliminate the noise in MATLAB

    - by Mertie Pertie
    I want to average some .jpg images which are corrupted by zero-mean Gaussian additive noise. After searching around, I figured out to add the image matrices and divide the sum by the number of matrices. However, the resultant image is totally black. Normally when the number of image increases then the resultant image gets better. But when I use more images it gets darker. I am using 800x600 black and white .jpg images. Here is the script I used: image1 = imread ('PIC1.jpg'); image2 = imread ('PIC2.jpg'); image3 = imread ('PIC3.jpg'); image4 = imread ('PIC4.jpg'); sum = image1 + image2 + image3 + image4; av = sum / 4; imshow(av);

  • Range annotation between nothing and 100?

    - by aticatac
    Hi I have a [Range] annotation that looks like this: [Range(0, 100)] public int AvailabilityGoal { get; set; } It works as it should, I can only enter values between 0 and 100 but I also want the input box to be optional, the user shouldn't get an validation error if the input box is empty. If the user leaves it empty it should make AvailabilityGoal = 0 but I don't want to force the user to enter a zero. I tried this but it (obviously) didn't work: [Range(typeof(int?), null, "100")] Is it possible to solve this with Data Annotations or in some other way? Thanks in advance. Bobby

  • JS 2 minute countdown then execute a function?

    - by Cyprus106
    I'm not that great at Javascript, for the record! I DO know how to use ajax. I just need a bit of help. I'm having a hard time figuring out how to display a 5 minute countdown, and once the countdown hits zero, to run a function. I need to pass a variable to the function that needs to run. I tried SetInterval but this isn't exactly my strong suit. Does anyone have any suggestions? I can post the code I've got, but I would equate it to a gorilla fumbling in the dark at a typewriter!

  • Problem about socket communication

    - by Ahmet Altun
    I have two separate socket projects in VS.NET. One of them is sender, other one is receiver. After starting receiver, i send data from sender. Although send method returns 13 bytes as successfully transferred, the receiver receives 0 (zero). The receiver accepts sender socket and listens to it. But cannot receive data. Why? P.S. : If sender code is put in receiver project, receiver can get data, as well.

  • Tool to diagonalize large matrices

    - by Xodarap
    I want to compute a diffusion kernel, which involves taking exp(b*A) where A is a large matrix. In order to play with values of b, I'd like to diagonalize A (so that exp(A) runs quickly). My matrix is about 25k x 25k, but is very sparse - only about 60k values are non-zero. Matlab's "eigs" function runs of out memory, as does octave's "eig" and R's "eigen." Is there a tool to find the decomposition of large, sparse matrices? Dunno if this is relevant, but A is an adjacency matrix, so it's symmetric, and it is full rank.

  • fortran error I/O

    - by jpcgandre
    I get this error when compiling: forrtl: severe (256): unformatted I/O to unit open for formatted transfers, unit 27, file C:\Abaqus_JOBS\w.txt The error occurs in the beginning of the analysis. At the start, the file w.txt is created but is empty. The error may be related to the fact that I want to read from an empty file. My code is: OPEN(27, FILE = "C:/Abaqus_JOBS/w.txt", status = "UNKNOWN") READ(27, *, iostat=stat) w IF (stat .NE. 0) CALL del_file(27, stat) SUBROUTINE del_file(uFile, stat) IMPLICIT NONE INTEGER uFile, stat C If the unit is not open, stat will be non-zero CLOSE(unit=uFile, status='delete', iostat=stat) END SUBROUTINE Ref: Close multiple files If you agree with my opion about the cause of the error, is there a way to solve it? Thanks

  • Excel - add target line to stacked bar chart

    - by Chris W
    I've got a stacked bar chart. I'm displaying a set of floating bars to represent hi/low ranges for some metrics, by using a transparent fill on the bottom section of the bar I achieve the desired look. What I now need to do is add a horizontal line across the chart to indicate how a particular users score relates to all of these hi/low ranges therefore the placement of this line needs to be dynamic based on a value in a cell. Is there anyway to do this as I can't find an easy option. If this was a simple bar chart I could add the target scores as new series and use the line chart type but I don't seem able to overlay a second series on the stacked bar chart. I'm using 2003 at the moment but run this in 2007 if that helps.

  • Avoid cache overflow in Atempo LiveBackup

    - by Vebjorn Ljosa
    When attempting the initial backup of a new client, Atempo LiveBackup seems to require a very large cache. For instance, a 20 GB cache is not enough to back up a computer that has 100 GB of data. It appears that LiveBackup is adding new files to the cache at a faster rate than it can send them to the server. When the cache fills up, the backup fails. Aside from removing most data from the computer and then add them back gradually after the initial backup, is there a good workaround? Is it possible to make LiveBackup slow down its scan so as to not fill the cache? Or is it possible to place the cache on an external drive?

  • VB.NET For Each steps into loop body for an IEnumerable collection! How? Why?

    - by Paul Sasik
    This is weird. I have a class that inherits from IEnumrable whose Count property is reporting 0 (zero) elements but the For Each loop steps into the loop body and tries to use the variable where it should just be moving on. My code: On Error Resume Next Dim d As Foo For Each d In fooCollection ' use d and throws an exception Next d Weirder still, every time d is accessed i get an exception thrown in the output window: A first chance exception of type 'System.NullReferenceException' but i'm not stopping on the exception (not in a try/catch block). Is "On Error Resume Next" causing this weirdness? Weirdness found: Per Rowland's and JohnH's comments i checked the Foo class: The GetEnumerator method inside of Foo didn't actually return anything! It had an empty body. That coupled with the On Error Resume Next before the loop caused the havoc! Wow this was ugly. Thanks for the clues guys!

  • Why does a C# System.Decimal remember trailing zeros?

    - by Rob Davey
    Is there a reason that a C# System.Decimal remembers the number of trailing zeros it was entered with? See the following example: public void DoSomething() { decimal dec1 = 0.5M; decimal dec2 = 0.50M; Console.WriteLine(dec1); //Output: 0.5 Console.WriteLine(dec2); //Output: 0.50 Console.WriteLine(dec1 == dec2); //Output: True } The decimals are classed as equal, yet dec2 remembers that it was entered with an additional zero. What is the reason/purpose for this?

  • Eliminating cyclic flows from a graph

    - by Jon Harrop
    I have a directed graph with flow volumes along edges and I would like to simplify it by removing all cyclic flows. This can be done by finding the minimum of the flow volumes along each edge in any given cycle and reducing the flows of every edge in the cycle by that minimum volume, deleting edges with zero flow. When all cyclic flows have been removed the graph will be acyclic. For example, if I have a graph with vertices A, B and C with flows of 1 from A?B, 2 from B?C and 3 from C?A then I can rewrite this with no flow from A?B, 1 from B?C and 2 from C?A. The number of edges in the graph has reduced from 3 to 2 and the resulting graph is acyclic. Which algorithm(s), if any, solve this problem?

  • Can't boot after Deleted System Reserved Partition

    - by mauris
    I accidentally deleted the System Reserved Partition and now I can no longer boot into Windows 7. The installation of Windows and all my files still exists in the partition, but without the System Reserved Partition I can no longer boot. After I deleted the System Reserved Partition I moved left the primary partition to fill the space. Is there any way I can "reinstall" that System Reserved Partition and the boot files? PS: I only have Windows 7 installed. No dual-boot nothing.

  • Problem with Silverlight/wpf in scrolling html div.

    - by Mat
    Hi all, I have a Silverlight object sitting at the bottom of a scrollable div. This object is submitted to a wcf backend via a javascript button. The problem is, as the silverlight is at the bottom of the scrollable div it is not viewable until you have scrolled down. This is generating an error when the javascript button is clicked ( if i havent scrolled down ) awfully strange, or am i just an idiot :/ if i scroll down so the silverlight object, so it is in view it submits just fine. The error i got is an alert type error which says : The parameter value must be greater than zero. Parameter name: pixelWidth This seems to be returned from the wcf service. What could cause this? Can anyone help me rectify. Kind regards Mat.

  • Morfik - suitability for medium-scale web enterprise applications

    - by MaikB
    I'm investigating technologies with which to develop a medium-scale (up to 100 or 200 simultaneous users) database-driven web application, and someone suggested Morfik. However, outside of the Morfik company I can find practically zero community support - no active blogs, no tutorials, no videos, no books - and this is of some concern (especially when compared to C# / ASP.NET / nHibernate etc support). Deciding between Morfik (untried and not used widely AFAIK) and the other technologies I mentioned (tried, tested, used widely) is becoming a critical issue for my company. Has anyone had success using Morfik in these kind of circumstances? What kind of performance did you achieve?

  • Ambiguous Evaluation of Lambda Expression on Array

    - by Joe
    I would like to use a lambda that adds one to x if x is equal to zero. I have tried the following expressions: t = map(lambda x: x+1 if x==0 else x, numpy.array) t = map(lambda x: x==0 and x+1 or x, numpy.array) t = numpy.apply_along_axis(lambda x: x+1 if x==0 else x, 0, numpy.array) Each of these expressions returns the following error: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() My understanding of map() and numpy.apply_along_axis() was that it would take some function and apply it to each value of an array. From the error it seems that the the lambda is being evaluated as x=array, not some value in array. What am I doing wrong? I know that I could write a function to accomplish this but I want to become more familiar with the functional programming aspects of python.

  • How to identify RAID (5 or 6) controllers that allow dynamic resize of the array

    - by David Pfeffer
    I'm building a server with a RAID5 array, based on a hardware controller. I want to be able to later add additional disks and have the array rebalance across all of the disks, enlarging the usable size. I also want to be able to later upgrade to bigger disks (one at a time, of course) and then expand the array to fill the entire drive. These features are available in Linux software raid (md). I've also heard they're available in some hardware controllers. Currently, I own the Adaptec RAID 3805 card and the 3ware 9650se card. I'd prefer to use the Adaptec if possible, but I can't find if either of these cards offer this feature. If they don't, are there other affordable (read as: sub-$600) RAID cards available that can accomplish this?

  • Standard (cross-platform) way for bit manipulation

    - by Kiril Kirov
    As are are different binary representation of the numbers (for example, take big/little endian), is this cross-platform: some_unsigned_type variable = some_number; // set n-th bit, starting from 1, // right-to-left (least significant-to most significant) variable |= ( 1 << ( n - 1 ) ); // clear the same bit: variable &= ~( 1 << ( n - 1 ) ); In other words, does the compiler always take care of the different binary representation of the unsigned numbers, or it's platform-specific? And what if variable is signed integral type (for example, int) and its value is zero positive negative? What does the Standard say about this? P.S. And, yes, I'm interesting in both - C and C++, please don't tell me they are different languages, because I know this :) I can paste real example, if needed, but the post will become too long
