• Design report of 4-D data set

  - by phq

  I'm writing a report generator that will present data each being generated from 4 parameters. Time interval Group Measurement value(one of several to choose from) Device All these are orthogonal giving me a 4-D dataset to present. There are some simplifications where one parameter is the same for all and other parameters are merged. Still it appears as there are situations where all values are wanted on the report. In short the report should both be simple to overview and contain details. There will also be an interface where the user setup the range and granularity for each parameter. The most naive solution would be to have a 2D table where each cell contain another table with values of the remaining two dimensions. This is technically feasible but I'm worried that it would become hard to overview. Another approach is to present first two dimensions in a 2D table and the remaining parameters in groups Are there any good method to address this kind of issue?

• Placing the where condition

  - by user182944

  I came up with the below query: SELECT ROOMNO,BUILDINGNO FROM MRM_ROOM_DETAILS WHERE ROOMID IN ( SELECT distinct roomid FROM MRM_BOOKING_DETAILS WHERE (CHECKIN NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00') AND (CHECKOUT NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00')) AND CAPACITY > 15 AND PROJECTIONSTATUS = 'NO'; I need to place this query in the method SQLiteDatabase.query() and fetch the rows accordingly. I am not able to understand how to place this big where condition (which contains a sub-query as well) in place of the "String selection" i.e. 3rd parameter of the method. Shall i simple write the entire where part(including the sub-query) as a string in the 3rd parameter or else there is some other better way for doing the same? Please suggest me the best way to do the same. Regards,

• WorkFlow and WCF dynamically launching WorkFlows

  - by Raj73

  I have a WF which will be hosted on WCF . The service Contract will contain a single operation containing two parameters. Parameter1 will be a string and will contain the name of the workflow to invoke and parameter two will contain the input for the invoked Work Flow. All operations will take the same parameter. All the operations will return the same return value. I have created the service implementation and I would like to depending on the value of parameter1 start executing the appropriate workflow and return the value (There can be number of workflow classes say Operation1, Operation2...which will be the passed in as the value in Parameter1). How can I instantiate different workflow classes and pass parameters and get the return values from them which I should then pass back to the calling Client. (Also Should I be using ReceiveActivities in all of my Launchable WorkFlow Classes ? ) Any code samples or pointers would help

• CodeIgniter: help with this query

  - by iamjonesy

  Hi, I have just started my first CI app. I have a view that displays some posts. Each post can have multiple comments and I want to display the total number of comments next to each post.

Any help with this most appreciated, Billy

• Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

  - by John Himmelman

  My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

• How to pass an object from a Frame to another Frame in a Windows 8 Style App

  - by Mythul

  I have problem that i just cant figure out right now. I am trying to develop a Windows-8 style app and im stuck implementing this functionality. I have a MainWindow which contains a ListBox and a Button (lets say addButton). When i click the button i navigate to a new page, lets say AddCustomerPage with this.Frame.Navigate(typeof (AddCustomerPage)); AddCustomerPage has 1 textBox and 1 button (lets say doneButton. When i click the button i want the string in the textBox to be added to the ListBox on the previous page. This is my current functionality: 1. MainWindow is created. Click addButton AddCustomer page is created. MainWindow is destroyed(problem). Click doneButton A MainWindow object is created with a ListBox with 1 item. Repeat the add process, i always get a MainWindow with a ListBox with 1 item. Thanks for the help. Here is the code: public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); this.brainPageController = new PageController(); // add items from the List<String> to the listBox listGoals.ItemsSource = brainPageController.GetListGoals(); } protected override void OnNavigatedTo(NavigationEventArgs e) { var parameter = e.Parameter as String; // a simple controller that adds a string to a List<string> brainPageController.AddGoal(parameter); } private void addButton_Click(object sender, RoutedEventArgs e) { this.Frame.Navigate(typeof (GoalsInfo)); } // VARIABLES DECLARATION private PageController brainPageController; } public sealed partial class GoalsInfo : WinGoalsWIP.Common.LayoutAwarePage { public GoalsInfo() { this.InitializeComponent(); this.brainPageController = new PageController(); } protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState) { } protected override void SaveState(Dictionary<String, Object> pageState) { } private void Button_Click_1(object sender, RoutedEventArgs e) { brainPageController.AddGoal(nameTextBox.Text); this.Frame.Navigate(typeof(MainPage), nameTextBox.Text); } // VARIABLES DECLARATION PageController brainPageController; }

• Dataset Binding stored procedures update/insert/delete

  - by Jin

  Hi all, I am currently having a problem since the DB has been changed. I am using Datasets for a c# application, and there is a user management system. For the security issues, our current DB design is like user log into app. DB returns a session ID On use of any other stored procedures, a session ID must be specified. BUT, the DB didn't request session ID before. since I am using the datasets, I used update/insert/delete stored procedures with "TableAdaptor Configuration Wizard". Bind Commands to Existing Stored Procedures (choose stored procedures to call and specify any reuiqred parameters) Now, it seems like I have to specify session ID for Insert/Update/Delete stored procedures. How do I specify session ID parameter here? It seems like I have to pick one return parameter variable from a select statement. Thanks,

• Error occurs while using SPADE method in R

  - by Yuwon Lee

  I'm currently mining sequence patterns using SPADE algorithm in R. SPADE is included in "arulesSequence" package of R. I'm running R on my CentOS 6.3 64bit. For an exercise, I've tried an example presented in http://en.wikibooks.org/wiki/Data_Mining_Algorithms_In_R/Sequence_Mining/SPADE When I tried to do "cspade(x, parameter = list(support = 0.4), control = list(verbose = TRUE))" R says: parameter specification: support : 0.4 maxsize : 10 maxlen : 10 algorithmic control: bfstype : FALSE verbose : TRUE summary : FALSE preprocessing ... 1 partition(s), 0 MB [0.096s] mining transactions ... 0 MB [0.066s] reading sequences ...Error in asMethod(object) : 's' is not an integer vector When I try to run SPADE on my Window 7 32bit, it runs well without any error. Does anybody know why such errors occur?

• Passing parameters among views in a navigation frame INSIDE a custom control

  - by NetWriter

  I created a silverlight 3 application with a navigation frame and 3 views: search, add and edit. I used the app file to pass parameters among the 3 pages, eg: ((App)Application.Current).SNIPSELECTED = currentSnip; Then in the receiving page: currentSnip = ((App)Application.Current).SNIPSELECTED; currentSnip is a SnipItem object: public class SnipItem { public string itemID {get;set;} public string category {get;set;} public string itemDescription {get;set;} public string codeSnip {get;set;} } This worked fine until I decided to make this entire application into a user control and put that inside a second silverlight application with its own navigation frame and app file. The app files are getting confused. The first app file with all my parameter passing is not being read. I know how to pass a simple parameter between views in the first application without the app file (in a query string), but how about these custom types like my currentSnip above?

• Template or function arguments as implementation details in doxygen?

  - by Vincent

  In doxygen is there any common way to specify that some C++ template parameters of function parameters are implementation details and should not be specified by the user ? For example, a template parameter used as recursion level counter in metaprogramming technique or a SFINAE parameter in a function ? For example : /// \brief Do something /// \tparam MyFlag A flag... /// \tparam Limit Recursion limit /// \tparam Current Recursion level counter. SHOULD NOT BE EXPLICITELY SPECIFIED !!! template<bool MyFlag, unsigned int Limit, unsigned int Current = 0> myFunction(); Is there any doxygen normalized option equivalent to "SHOULD NOT BE EXPLICITELY SPECIFIED !!!" ?

• Visual Basic Display Square

  - by user1724157

  Alright I'm currently lost on a particular assignment I have for a class. I've seen many examples of this app but none of them see to help my problem is as follows: Write a Sub procedure "DisplaySquare" to display the solid square. The size should be specified by the integer parameter "size". The character that fills the square should be specified by the string parameter "fillCharacter. Use a For...Next statement nested within another For...Next statement to create the square. The outer For...Next specifies what row is currently being displayed. The inner For...Next appends all the characters that form the row to a display string. So it should come out like as follows: if a user enters "8" and "#" ######## ######## ######## ######## ######## ######## ######## ######## Any help would be appreciated.

• Recursion: using values passed in parameters

  - by Tom Lilletveit

  I got this line of code that pops a int of the array saves it to int element then removes it from array. then in the return statement return CountCriticalVotes(rest, blockIndex + element); it ads it to the blockIndex variable and if it reaches 10 before the array is empty it returns 1. But my problem is this, I do not want it to add up all the values in the array in the parameter, but only add one then revert the parameter value back to it´s original state, then add a new, revert etc... How would i do this? int NumCriticalVotes :: CountCriticalVotes(Vector<int> & blocks, int blockIndex) { if (blockIndex >= 10) { return 1; } if (blocks.isEmpty()) { return 0; } else { int element = blocks.get(0); Vector<int> rest = blocks; rest.remove(0); return CountCriticalVotes(rest, blockIndex + element);

• Passing javascript to a function

  - by AJ

  Hello, Can I pass some Javascript to a function and then execute that Javascript from within the function, e.g. test("a = 1; b = 2; test2(a,b);"); function test(js) { // execute dynamically generated JS here. } Basically I have some code that is generated on the server and I want to pass that code to a JS function which when it has finished processing it executes the code passed as a parameter. This could also be useful for the parameter of setTimeout, then the code passed could be executed in the timeout event. Can this be done?

• Django store regular expression in DB which then gets evaluated on page

  - by John

  Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks

• How can I change this method to get rid of the warning without anything changing?

  - by user3591323

  So this question:Warning-used as the name of the previous parameter rather than as part of the selector answers part of my problem, but I really don't want anything to change inside this method and I'm a bit confused on how this works. Here's the whole method: -(void) SetRightWrong:(sqzWord *)word: (int) rightWrong { if (self.mastered==nil) { self.mastered = [[NSMutableArray alloc]initWithCapacity:10]; } //if right change number right if (rightWrong == 1) { word.numberCorrect++; //if 3 right move to masterd list [self.onDeck removeObject:word]; if(word.numberCorrect >= 3 ) { [self.mastered addObject:word]; } else { //if not 3 right move to end of ondeck [self.onDeck addObject:word]; } } else if(rightWrong == 0) { //if wrong remove one from number right unless 0 NSUInteger i; i=[self.onDeck indexOfObject:word]; word = [self.onDeck objectAtIndex:i]; if (word.numberCorrect >0) { word.numberCorrect--; } } } The warning I am getting is: 'word' used as the name of the previous parameter than as part of the selector.

• Interesting XSL Dilemma

  - by bobber205

  I've got this issue. A template called "checkbox" that's called from while inside a table HTML element and also outside of it. To solve an issue, I've added tags to "checkbox" input control. Here's what I'd like to do to but I'm not sure if it's possible or not. When I hit my "row" (part of the custom table markup) template, I would set some variable or pass some parameter, that for each template applied afterwards, would know it was in a "row" and do something special based on this information. I know I can't add parameters to apply-templates. I may be able to add a row "mode" but I can't make changes to each template and have one copy with the mod parameter and one without. Thanks for any suggestions. I know the ideal solution would to be to make changes to the XML but I'm not sure if I can do that as this point. That's a "content" issue. :P Thanks!

• XmlResolver Class' GetEntity function

  - by Pok

  I wrote a custom resolver class. It works OK for resolving SYSTEM DTDs, but not for resolving PUBLIC DTDs. When the class has to resolve PUBLIC DTDs instead of the URI of the resource, the function receives the public identifier through the absoluteUri parameter of the GetEntity function. Is there a solution to this. In examples: if I have a DTD declaration like <!DOCTYPE document SYSTEM "document.dtd"> then the custom resolver correctly receives the string "document.dtd" through the absoluteUri parameter of the GetEntity function. if I have a DTD declaration like <!DOCTYPE document PUBLIC "-//Organization//DTD Document 1.0//EN" "http://localhost/document.dtd"> then the custom resolver incorrectly receives the string "-//Organization//DTD Document 1.0//EN" instead of "scheme://host/document.dtd".

  i did this in msvc 2005. typedef void (*cleanup_t)(); void func(cleanup_t clean) { cleanup_t(); } Why does this compile? and not give me a warning? ok, it gave me a unreferenced formal parameter warning but originally i did this when clean was in a class no there was no unreferenced formal parameter when this code gave me problems. What is cleanup_t(); really doing and what is the point? now for laughs i tried int() and that worked also.

• How to assure applying order of function decorators in Python?

  - by Satoru.Logic

  Some decorators should only be used in the outermost layer. A decorator that augments the original function and add a configure parameter is one example. from functools import wraps def special_case(f): @wraps(f) def _(a, b, config_x=False): if config_x: print "Special case here" return return f(a, b) How can I avoid decorators like this getting decorated by another decorator? EDIT It is really disgusting to let everyone trying to apply a new decorator worry about the application order. So, is it possible to avoid this kind of situation? Is it possible to add a config option without introducing a new parameter?

• Why does FrameworkElement's FindResource() Method Accept an Object and not a String?

  - by ChrisNel52

  I understand that calling FindResource() on a FrameworkElement (e.g. a Window) can be used to find a resource in the FrameworkElement's ResourceDictionary. For example, I've used it many times to access a Style through code to add a new Setter to the Style dynamically. I always pass the x:Key value of the Style as a string into the FindResource() method. Like... Style style = w.FindResource("GridDescriptionColumn") as Style; My question is, I noticed that FindResource() accepts an argument of type object and not an argument of type string. I can't for the life of my think of a reason I would call FindResource() with an argument that is not a string. It makes me think that I may unaware of other ways to use FindResource(). Does anyone know why FindResource() accepts a parameter type of object and not string? If so, what would be an example of calling FindResource() with a parameter type other than a string? Thanks.

• Silverlight 4 Binding to ConverterParameter

  - by FrEEzE2046

  Hello everybody, I have a ValueConverter which needs to be called with a dynamic parameter, depending on a property. I can't see a way to do this ... Width="{Binding ActualWidthValue, Source={StaticResource VisibleSize}, Converter={StaticResource Fraction}}" The "Fraction" converter get's (or should get) a parameter of type System.Size, which contains a numerator and denumerator. This value (should) depend on a ItemCollection.Count. Resetting the ItemCollection should reinvoke the Converter with the new values. My first idea was to manually change the ConverterParameter in CodeBehind on the PropertyChanged event of my ItemCollection DependencyProperty. But, as I know now, Silverlight has no GetBinding() method. I heard about GetBindingExpression and tried to do. But MyGrid.GetBindingExpression(Grid.ActualHeightProperty) is always returning null, although the Binding is already established. So, what can I do to reach my target?
