  • asp:repeater events - how to postback

    - by Kieran
    Hello I have an ASP:Repeater Which I would like to display a list of check boxes in. These check boxes are related to a list of user preferences and the users resulting answer. See Code Bellow. I would like to add do one of the following if possible Option 1: It would be great if I could use the Event in the Repeater:OnItemCommand(...) to fire if any of the items change. It would seem to me that this event will only fire if there is a Button | LinkButton | ImageButton item in the list. IE it will not fire if I put in a check box with AutopostBack="True" Option 2: Is there a way I could attach a method to an Event of CheckBox:CheckChanged I would need to pass this method a parameter saying which question/answer combo to change. Option 3: Its your answer if you know an easier way that would be awesome. The Code: <asp:Repeater ID="RPTprefs" runat="server" DataSourceID="getAnswers" OnItemCommand="RPTprefs_ItemCommand"> <ItemTemplate> <li><asp:CheckBox ID='questionID' runat="server" Checked='<%# Eval("pr.up_is_selected") %>' Text='<%# Eval("prp.prefs_question") %>' AutoPostBack="true" OnCheckedChanged="CheckChanged" /></li> </ItemTemplate> </asp:Repeater> Thanks in advance

  • Testing the context in asp.net mvc

    - by user252160
    I got pretty experienced with testing controllers, my question here is though, aren't we supposed to test the data context as well, and how ? I mean, there are a lot of relationships and constraints coming from the DB that simply testing controllers does not cover. On the other hand, testing against the DB is not considered a good practice - what then ? Simply testing without db.SubmitChanges() or what ?

  • WPF Spellcheck Engine takes up too much memory.

    - by Matt H.
    Each datatemplate in my WPF ItemsControl contains FIVE custom bindable richtextbox controls. It is a data-driven app that for authoring multiple-choice questions -- The question and four answer choices must all support: 1) Spell check 2) Rich formatting (otherwise I'd use regular textboxes) The spell check object in .NET 4 has a Friend constructor that takes a single argument of owner As TextBoxBase This means every richtextbox in the ItemsControl has 5 Spellcheck objects! This is the problem -- every spell check engine is consuming about 500k memory. So after you favor in the spellcheck, bindings, additional controls in the DataTemplate, etc.. a single multi choice question consumes more than 3MB memory. Users with 100--200 questions will quickly see the App raise it's memory consumption to 500+ MB. Management is definitely not OK with this. Is there a way to minimimze this problem? The best suggestion I've heard is to enable/disable spellcheck if the richtextbox is in the ItemsControl's scrollviewer: I haven't gotten an answer to how to go about it: (http://stackoverflow.com/questions/2869012/possible-to-implement-an-isviewportvisible-dependencyproperty-for-an-item-in-an-i) Any good ideas?

  • Checking if an array contains all elements of another array

    - by mozcelikors
    I'm designing an electrical engineering application. However, i'm stuck on this: I have the following array <?php // Static Array $GroupOfEight = array ( array(0,1,3,2,4,5,7,6), array(4,5,6,7,16,12,13,14), array(12,13,15,14,8,9,11,10), array(2,6,14,10,3,7,15,11), array(1,3,5,7,13,15,9,11), array(0,4,12,8,1,5,13,9), array(0,1,3,2,8,9,11,10) ); ?> And I have another array, but this one is one dimensional. <?php $myStack = array(0,1,3,2,4,5,7,6); //Dynamic, gets value by POST method. ?> What I want to do is to check if $myStack is equal to any sub array of $GroupOfEight array. ( Number ordering is not important. The script should just check if every elements contained. It's not important if their order is same or not. ) Here is what I've done to solve the issue so far: <?php //Check if stackArray contains 8group for($i=0; $i<count($GroupOfEight);$i++) for($j=0; $j<count($GroupOfEight[$i]); $j++){ //$containsSearch = count(array_intersect($search_this,$all)) == count($search_this); $containsSearch = count(array_intersect($stackArray,$GroupOfEight[$j])) == count($stackArray); echo $containsSearch; } ?> Please help me correct my code or introduce me the solution of this issue, Thanks.

  • Building a DLL via Maven with mojo-native

    - by graham.reeds
    I can build a simple dll consisting of a source file, a header file and a definition but now I am progressing beyond a simple toy dll and working towards something more real (ie: more complex). The DLL I am trying to compile has 2 source files, 2 headers and the dreaded stdafx pair. To compile normally you would use /Yc for the pch and /Yu to use it. How do you specify that with in the constraints of mojo-native's compiler options?

  • Django: Only one of two fields can be filled in

    - by Giovanni Di Milia
    I have this model: class Journals(models.Model): jid = models.AutoField(primary_key=True) code = models.CharField("Code", max_length=50) name = models.CharField("Name", max_length=2000) publisher = models.CharField("Publisher", max_length=2000) price_euro = models.CharField("Euro", max_length=2000) price_dollars = models.CharField("Dollars", max_length=2000) Is there a way to let people fill out either price_euro or price_dollars? I do know that the best way to solve the problem is to have only one field and another table that specify the currency, but I have constraints and I cannot modify the DB. Thanks!

  • Mock Object Data

    - by Nissan Fan
    I'd like to mock up object data, not the objects themselves. In other words, I would like to generate a collection of n objects and pass it into a function which generates random data strings and numbers. Is there anything to do this? Think of it as a Lorem Ipsum for object data. Constraints around numerical ranges etc. are not necessary, but would be a bonus.

  • ADO.NET zombie transaction bug? How to ensure that commands will not be executed on implicit transac

    - by TN
    e.g. When deadlock occurs, following SQL commands are successfully executed, even if they have assigned SQL transaction that is after rollback. It seems, it is caused by a new implicit transaction that is created on SQL Server. Someone could expect that ADO.NET would throw an exception that the commands are being executed on a zombie transaction. However, such exception is not thrown. (I think this is a bug in ASP.NET.) Moreover, because of zombie transaction the final Dispose() silently ignores the rollback. Any ideas, how can I ensure that nobody can execute commands on implicit transaction? Or, how to check that transaction is zombie? I found that Commit() and Rollback() check for zombie transaction, however I can call them for a test:) I also found that also reading IsolationLevel will do the check, but I am not sure whether simple calling transaction.IsolationLevel.ToString(); will not be removed by a future optimizer. Or do you know any other safe way invoke a getter (without using reflection or IL emitting)?

  • Faster integer division when denominator is known?

    - by aaa
    hi I am working on GPU device which has very high division integer latency, several hundred cycles. I am looking to optimize divisions. All divisions by denominator which is in a set { 1,3,6,10 }, however numerator is a runtime positive value, roughly 32000 or less. due to memory constraints, lookup table is not option. Can you think of alternatives? I have thought of computing float point inverses, and using those to multiply numerator. Thanks

  • Dependency Injection for objects that require parameters

    - by Andrew
    All of our reports are created from object graphs that are translated from our domain objects. To enable this, we have a Translator class for each report, and have been using Dependency Injection for passing in dependencies. This worked great, and would yield nice classes structured like this: public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc) { _empSvc = empSvc; _paySvc = paySvc; } public Check CreateCheck() { //do the translation... } } However, in some cases the mapping has many different grouping options. As a result, the c-tor would turn into a mix of class dependencies and parameters. public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc , bool doTranslateStubData , bool doAttachLogo) { _empSvc = empSvc; _paySvc = paySvc; _doTranslateStubData = doTranslateStubData; _doAttachLogo = doAttachLogo; } public Check CreateCheck() { //do the translation... } } Now, we can still test it, but it no longer really works with an IoC container, at least in a clean fashion. Plus, we can no longer call the CreateCheck twice if the settings are different for each check. While I recognize it's a problem, I don't necessarily see the right solution. It seems kind of strange to create a Factory for each class ... or is this the best way?

  • Entity Framework and stored procedure returning temp table Issues

    - by kaplooeymom
    (Disclaimer - I'm not the database designer. I'm just the poor developer what has to make this work.) There are 17 (at the moment) tables with identical structure - name, address, phone number. Given a phone number, I have to check to see if there's a matching entry in any of the tables, then return that address. So, I created a view to get the list of tables (there's a ref table that holds that info), then I created a stored procedure to create a temp table, using cursors, check each table in the view for the phone number, using sql concatenation. If a record is found, insert it into the temp table. return the rows from the temp table. This all works in straight T-SQL. Now, I'm trying to use Entity Framework 4+ to call the stored procedure. But the function import interface won't generate columns. It says return type = none, and the LINQ code expects an int and won't compile. Any ideas on how to make this work? I know I can move the check tables part to code, if I absolutely have to, but I'd rather have the above method work.

  • Errors In Programmatically Running ANT Build In Eclipse

    - by Sujay
    I am trying to run an ANT script through a small Java program and I keep on encountering the following error: build: Exception in thread "main" build.xml:7: Problem: failed to create task or type eclipse.refreshLocal Cause: The name is undefined. Action: Check the spelling. Action: Check that any custom tasks/types have been declared. Action: Check that any <presetdef>/<macrodef> declarations have taken place. at org.apache.tools.ant.UnknownElement.getNotFoundException(UnknownElement.java:487) at org.apache.tools.ant.UnknownElement.makeObject(UnknownElement.java:419) at org.apache.tools.ant.UnknownElement.maybeConfigure(UnknownElement.java:163) I used to get this problem when I used to execute the build file manually. All I had to do to make Eclipse run this build was to go to Run External Tools External Tools Configuration JRE and select "Run in the same JRE as the workspace" and then attempt to execute. But I have no idea how to achieve the same effect through my code. Any suggestion would really be appreciated. Note that this has reference to a previous question that I asked over here

  • How to test a struts 2.1.x developer?

    - by Jason Pyeron
    We employ test to filter out those who can't. The tests are designed to be very low effort for those who can and too much effort for those who can't. Here is an example for java web application developer on an Oracle project: We only work with contractors who can use the tools we use, to determine if you can use the tools we have devised some very simple tests. Instructions If you are prepared and knowledgeable this will take you about 2-5 minutes. Suggested knowledge and tools: * subversion 1.6 see http://subversion.tigris.org/ or http://cygwin.com/setup.exe * java 1.6 see http://java.sun.com/javase/downloads/index.jsp * oracle >=10g see http://www.oracle.com/technology/software/products/jdev/index.html * j2ee server see http://tomcat.apache.org/download-55.cgi or http://www.jboss.org/jbossas/downloads/ Steps 1. check out svn://statics32.pdinc.us/home/subversion/guest 2. deploy the war file found at trunk/test.war 3. browse to the web application you installed from the war file and answer the one SQL question: How many rows are in the table 'testdata' where column 'value' ends with either an 'A' or an 'a'? The login credentials are in trunk/doc/oracle.txt 4. make a RESULTS HASH by submitting your answer to the form. 5. create a file in tmp/YourUserName.txt and put the RESULTS HASH in it, not the answer. 6. check in your file (don't forget to add the file first). 7. message me with the revision number of your check in. As such I am looking for ideas on how to test for someone to be a struts 2.1 w/ annotations.

  • How to formulate a SQL Server indexed view that aggregates distinct values?

    - by Jeremy Lew
    I have a schema that includes tables like the following (pseudo schema): TABLE ItemCollection { ItemCollectionId ...etc... } TABLE Item { ItemId, ItemCollectionId, ContributorId } I need to aggregate the number of distinct contributors per ItemCollectionId. This is possible with a query like: SELECT ItemCollectionId, COUNT(DISTINCT ContributorId) FROM Item GROUP BY ItemCollectionId I further want to pre-calculate this aggregation using an indexed (materialized) view. The DISTINCT prevents an index being placed on this view. Is there any way to reformulate this which will not violate SQL Server's indexed view constraints?

  • How to implement "business rules" in Rails?

    - by Zabba
    What is the way to implement "business rules" in Rails? Let us say I have a car and want to sell it: car = Cars.find(24) car.sell car.sell method will check a few things: does current_user own the car? check: car.user_id == current_user.id is the car listed for sale in the sales catalog? check: car.catalogs.ids.include? car.id if all o.k. then car is marked as sold. I was thinking of creating a class called Rules: class Rules def initialize(user,car) @user = user @car = car end def can_sell_car? @car.user_id == @user.id && @car.catalogs.ids.include? @car.id end end And using it like this: def Car def sell if Rules.new(current_user,self).can_sell_car ..sell the car... else @error_message = "Cannot sell this car" nil end end end As for getting the current_user, I was thinking of storing it in a global variable? I think that whenever a controller action is called, it's always a "fresh" call right? If so then storing the current user as a global variable should not introduce any risks..(like some other user being able to access another user's details) Any insights are appreciated! UPDATE So, the global variable route is out! Thanks to PeterWong for pointing out that global variables persist! I've now thinking of using this way: class Rules def self.can_sell_car?(current_user, car) ......checks.... end end And then calling Rules.can_sell_car?(current_user,@car) from the controller action. Any thoughts on this new way?

  • JSF/ADF/PPR can't refresh the page as expected

    - by Nhut Le
    Hi, I am having issues with JSF/ADF/PPR on refreshing the page incorrectly. I have a selectManyCheckBox with 5 options in it, one of the option is 'All'. If users check that checkbox, I should check all the others. <h:panelGrid styleClass="myBox leftAligned" id="applyChangesBox"> <af:selectManyCheckbox id="changesCheckedBox" autoSubmit="true" label="Hello: " value="#{updateForm.applyChangesList}" valueChangeListener="#{updateForm.testValueChanged}"> <af:selectItem value="A" label="All Changes"/> <af:selectItem value="R" label="Residential Address"/> <af:selectItem value="M" label="Mailing Address"/> <af:selectItem value="P" label="Personal Phone/Fax Numbers"/> <af:selectItem value="E" label="Personal Email Addresses"/> </af:selectManyCheckbox> <af:outputText value="#{updateForm.testValue}" partialTriggers="changesCheckedBox"/> </h:panelGrid> I am using valueChangeListener so that I can see my bean updated and printed out correctly, but my page does not refresh and check all the other checkbox if I need to.

  • Can UML with OCL be used for formal specifications?

    - by Gabriel Šcerbák
    I am asking because UML is used for informal specifications and has some ambiguities in its semantics. However OCL can be used to specify pre/post conditions and invariants and other constraints quite efficiently I think. I encountered the Z notation and algebraic specifications recently. My question, is combination of UML and OCL sufficient for formal specifications?

  • Sparse quadratic program solver

    - by Jacob
    This great SO answer points to a good sparse solver, but I've got constraints on x (for Ax = b) such that each element in x is >=0 an <=N. The first thing which comes to mind is an QP solver for large sparse matrices. Also, A is huge (around 2e6x2e6) but very sparse with <=4 elements per row. Any ideas/recommendations?

Can anyone please let me know the workaround?
