  • Permission error while trying to access Sql from a web method

    - by Pavan Reddy
    I created a web service which has a few web methods which inturn performs inserts/updates/select from a Sql Server and return non-primitive types. To test the web methods I tried using the Open source tool .net web service studio When I test for the web methods, I get the following error - Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I searched for solutions and I tried a lot of approaches like setting up the permission levels, the trust level in config file etc. But the error still persists. Can anyone tell me what could be the reason for this error? I have tried toggling the permissions at all levels - Sql Server, web service etc. How can I fix this error?

    - by mattgcon
    I have a few webcombo boxes that are hierachial: Continent Country When the form loads everything works fine, when I change the continent the first time, the country repopulates correctly. However if I change the continent a second time I receive an error: Specified argument was out of the range of valid values.Parameter name: The DataValueField of ValueField was not found in the Columns collection. Can anyone tell me why? P.S. This is all I have in the Page_Load event if (!IsPostBack) { this.Load_AreaList(); this.Load_AreasOfInterest(); this.Load_Degrees(); this.Load_GenderList(); this.Load_ParticipationDateModifiers(); this.Load_ProgramCategories(nEventID); this.Load_YesNoList(); this.Load_ParticipantInformation(nParticipantID); }

  • While using ConcurrentQueue, trying to dequeue while looping through in parallel

    - by James Black
    I am using the parallel data structures in my .NET 4 application and I have a ConcurrentQueue that gets added to while I am processing through it. I want to do something like: personqueue.AsParallel().WithDegreeOfParallelism(20).ForAll(i => ... ); as I make database calls to save the data, so I am limiting the number of concurrent threads. But, I expect that the ForAll isn't going to dequeue, and I am concerned about just doing ForAll(i => { personqueue.personqueue.TryDequeue(...); ... }); as there is no guarantee that I am popping off the correct one. So, how can I iterate through the collection and dequeue, in a parallel fashion. Or, would it be better to use PLINQ to do this processing, in parallel?

  • How to handle management trying to interfere with the project (including architecture decision)

    - by Zwei Steinen
    I feel this is not a very good question to post on SO, but I need some advice from experienced developers... (I'm a second year developer) I guess this is a problem to many, many projects, but in our case, it is getting intense. There were so much interference from people that don't know a bit about software development, that our development came to an almost complete stop. We had to literary escape to another location to get any useful job done. Now we were happily producing results, but then I get a request for a "meeting" and it's them again. I have a friendly relationship with them, but I feel very daunted at the thought of talking about non-sense all over again. Should I be firm and tell them to shut up and wait for our results? Or should I be diplomatic and create an illusion they are making a positive contribution or something?? My current urge is to be unfriendly and murmur some stuff so they will give up or something. What would you do if you were in this situation?

  • Encountering NullPointerException when trying to add polynoms

    - by Ayler Cruz
    I need to add two polynomials, which is composed of two ints. For example, the coefficient and the exponent 3x^2 would be constructed using 3 and 2 as parameters. I am getting a NullPointerException but I can't figure out why. Any help would be appreciated! public class Polynomial { private Node poly; public Polynomial() { } private Polynomial(Node p) { poly = p; } private class Term { int coefficient; int exponent; private Term(int coefficient, int exponent) { this.coefficient = coefficient; this.exponent = exponent; } } private class Node { private Term data; private Node next; private Node(Term data, Node next) { this.data = data; this.next = next; } } public void addTerm(int coeff, int exp) { Node pointer = poly; if (pointer.next == null) { poly.next = new Node(new Term(coeff, exp), null); } else { while (pointer.next != null) { if (pointer.next.data.exponent < exp) { Node temp = new Node(new Term(coeff, exp), pointer.next.next); pointer.next = temp; return; } pointer = pointer.next; } pointer.next = new Node(new Term(coeff, exp), null); } } public Polynomial polyAdd(Polynomial p) { return new Polynomial(polyAdd(this.poly, p.poly)); } private Node polyAdd(Node p1, Node p2) { if (p1 == p2) { Term adding = new Term(p1.data.coefficient + p2.data.coefficient, p1.data.exponent); p1 = p1.next; p2 = p2.next; return new Node(adding, null); } if (p1.data.exponent > p2.data.exponent) { p2 = p2.next; } if (p1.data.exponent < p2.data.exponent) { p1 = p1.next; } if (p1.next != null && p2.next != null) { return polyAdd(p1, p2); } return new Node(null, null); } }

    New to PHP, and wondering what is wrong with this code because its definitely not switching the header img. This is what is used to be: <a href="http://www.finegra.in"><img id="logo" alt="fine grain Logo" src="http://www.finegra.in/wp-content/uploads/2012/04/fineGRAINlogoGOOD-WEB.png"> This is what I changed it to: <?php if (is_home()) { ?> <a href="http://www.finegra.in"><img id="logo" alt="fine grain Logo" src="http://www.finegra.in/wp-content/uploads/2012/09/finegrain-logo-sept.png"> </a> <?php } else { ?> <a href="http://www.finegra.in"><img id="logo" alt="fine grain Logo" src="http://www.finegra.in/wp-content/uploads/2012/04/fineGRAINlogoGOOD-WEB.png"> </a> <?php } ?>

  • Trying to use jquery ui in google chrome extension in the content level

    - by user135697
    The problem is that the scope of the content script is on the web page that your plugin is suppose to be used at. So the css background:url(images/ui-bg_inset-hard_100_fcfdfd_1x100.png) becomes url('http://webpageforplugin/images/ui-bg_inset-hard_100_fcfdfd_1x100.png') in order for this to work as far as i understood i need to have it to point to: url('chrome-extension://extensionId/images/ui-bg_inset-hard_100_fcfdfd_1x100.png') So i tried to haxorz the document.styleSheets var ss = document.styleSheets; for (var i=0; i<ss.length; i++) { var found=-1, x,i; var rules = ss[i].cssRules || ss[i].rules; for (var j=0; j<rules.length; j++) { if ('.ui-helper-hidden'==rules[j].selectorText){ found=i; break; } } if (found>-1){ for (var j=0; j<rules.length; j++) { if (x=rules[j].style.background){ if ((i=x.indexOf('url'))!=-1) rules[j].style.background = x.replace('http://page/images/','chrome-extension://extensionId/images/'); } } break; } }; I feel that i'm missing the obvious. That there must be an easier way. Even if i manage to change this how will i get the extension id to build the string. Btw this doesn't work, the icons are not properly fetched. (I hardcoded the extension id) Any ideas?

  • Trying to make a plugin system in C++/Qt

    - by Pirate for Profit
    I'm making a task-based program that needs to have plugins. Tasks need to have properties which can be easily edited, I think this can be done with Qt's Meta-Object Compiler reflection capabilities (I could be wrong, but I should be able to stick this in a QtPropertyBrowser?) So here's the base: class Task : public QObject { Q_OBJECT public: explicit Task(QObject *parent = 0) : QObject(parent){} virtual void run() = 0; signals: void taskFinished(bool success = true); } Then a plugin might have this task: class PrinterTask : public Task { Q_OBJECT public: explicit PrinterTask(QObject *parent = 0) : Task(parent) {} void run() { Printer::getInstance()->Print(this->getData()); // fictional emit taskFinished(true); } inline const QString &getData() const; inline void setData(QString data); Q_PROPERTY(QString data READ getData WRITE setData) // for reflection } In a nutshell, here's what I want to do: // load plugin // find all the Tasks interface implementations in it // have user able to choose a Task and edit its specific Q_PROPERTY's // run the TASK It's important that one .dll has multiple tasks, because I want them to be associated by their module. For instance, "FileTasks.dll" could have tasks for deleting files, making files, etc. The only problem with Qt's plugin setup is I want to store X amount of Tasks in one .dll module. As far as I can tell, you can only load one interface per plugin (I could be wrong?). If so, the only possible way to do accomplish what I want is to create a FactoryInterface with string based keys which return the objects (as in Qt's Plug-And-Paint example), which is a terrible boilerplate that I would like to avoid. Anyone know a cleaner C++ plugin architecture than Qt's to do what I want? Also, am I safely assuming Qt's reflection capabilities will do what I want (i.e. able to edit an unknown dynamically loaded tasks' properties with the QtPropertyBrowser before dispatching)?

  • Jquery .Ajax error when trying to POST data in ASP.NET MVC

    I am unable to access an action in my controller using .ajax. The code works on my development machine but as soon as I place it on the server it gives the error 401 Unauthorized. Here is a snippet of the code in the .aspx file... var encoded = $.toJSON(courseItem); $.ajax({ url: '<%= Url.Action("ViewCourseByID", "Home") %>/', type: "POST", dataType: 'json', data: encoded, //contentType: "application/json; charset=utf-8", success: function(result) { Update: The only time this doesn't work is when I pass json data to the Ajax call, it works fine with HTML data.

  • .NET TreeView causes application to crash when trying to check Parent node

    - by alexD
    I have a TreeView with check boxes, and when a user checks a child node, I want to go up the tree and check each parent. However, for some reason my application blows up whenever I touch the parent node. For the nodes in my tree, I've extended TreeNode to create my own objects with some data that I need to store in them, but I still reference them as TreeNodes when checking/unchecking. My code looks like this: //checkBox checked event handler if (node.Parent != null) { checkAllParents(node.Parent); } // private void checkAllParents(TreeNode node) { node.Checked = true; if (node.Parent != null) { checkAllParents(node.Parent); } }

  • Trying to verify understanding of Foreign Keys MSSQL

    - by msarchet
    So I'm working on just a learning project to expose myself to doing some things I do not get to do at work. I'm just making a simple bug and case tracking app (I know there are a million this is just to work with some tools I don't get to). So I was designing my database and realized I've never actually used Foreign Keys before in any of my projects, I've used them before but never actually setting up a column as a FK. So I've designed my database as follows, which I think is close to correct (at least for the initial layout). However When I try to add the FK's to the linking Tables I get an error saying, "The tables present in the relationship must have the same number of columns". I'm doing this by in SQLSMS by going to the Keys 'folder' and adding a FK. Is there something that I am doing wrong here, I don't understand why the tables would have to have the same number of columns for me to add a FK relationship between the tables?

  • Trying to sentinel loop this program. [java]

    - by roger34
    Okay, I spent all this time making this for class but I have one thing that I can't quite get: I need this to sentinel loop continuously (exiting upon entering x) so that the System.out.println("What type of Employee? Enter 'o' for Office " + "Clerical, 'f' for Factory, or 's' for Saleperson. Enter 'x' to exit." ); line comes back up after they enter the first round of information. Also, I can't leave this up long on the (very) off chance a classmate might see this and steal the code. Full code following: import java.util.Scanner; public class Project1 { public static void main (String args[]){ Scanner inp = new Scanner( System.in ); double totalPay; System.out.println("What type of Employee? Enter 'o' for Office " + "Clerical, 'f' for Factory, or 's' for Saleperson. Enter 'x' to exit." ); String response= inp.nextLine(); while (!response.toLowerCase().equals("o")&&!response.toLowerCase().equals("f") &&!response.toLowerCase().equals("s")&&!response.toLowerCase().equals("x")){ System.out.print("\nInvalid selection,please enter your choice again:\n"); response=inp.nextLine(); } char choice = response.toLowerCase().charAt( 0 ); switch (choice){ case 'o': System.out.println("Enter your hourly rate:"); double officeRate=inp.nextDouble(); System.out.println("Enter the number of hours worked:"); double officeHours=inp.nextDouble(); totalPay = officeCalc(officeRate,officeHours); taxCalc(totalPay); break; case 'f': System.out.println("How many Widgets did you produce during the week?"); double widgets=inp.nextDouble(); totalPay=factoryCalc(widgets); taxCalc(totalPay); break; case 's': System.out.println("What were your total sales for the week?"); double totalSales=inp.nextDouble(); totalPay=salesCalc(totalSales); taxCalc(totalPay); break; } } public static double taxCalc(double totalPay){ double federal=totalPay*.22; double state =totalPay*.055; double netPay = totalPay - federal - state; federal =federal*Math.pow(10,2); federal =Math.round(federal); federal= federal/Math.pow(10,2); state =state*Math.pow(10,2); state =Math.round(state); state= state/Math.pow(10,2); totalPay =totalPay*Math.pow(10,2); totalPay =Math.round(totalPay); totalPay= totalPay/Math.pow(10,2); netPay =netPay*Math.pow(10,2); netPay =Math.round(netPay); netPay= netPay/Math.pow(10,2); System.out.printf("\nTotal Pay \t: %1$.2f.\n", totalPay); System.out.printf("State W/H \t: %1$.2f.\n", state); System.out.printf("Federal W/H : %1$.2f.\n", federal); System.out.printf("Net Pay \t: %1$.2f.\n", netPay); return totalPay; } public static double officeCalc(double officeRate,double officeHours){ double overtime=0; if (officeHours>=40) overtime = officeHours-40; else overtime = 0; if (officeHours >= 40) officeHours = 40; double otRate = officeRate * 1.5; double totalPay= (officeRate * officeHours) + (otRate*overtime); return totalPay; } public static double factoryCalc(double widgets){ double totalPay=widgets*.35 +300; return totalPay; } public static double salesCalc(double totalSales){ double totalPay = totalSales * .05 + 500; return totalPay; } }
