  • Domino 9 / Dojo 1.8 - Date Time Picker without default value

    - by Julian Buss
    I want a Date Time Picker control WITHOUT a default value. Doesn't seem to be possible anymore :-( To reproduce, create a blank XPage and place a Date Time Picker control. Open the XPage in the browser and you will see that it defaults to today. I didn't found any way to set the default to an empty value. I tried setting all properties/data/default to 0, null, empty string and so on - no luck. I tried the data-dojo-probs attribute with value:'', this sets the default to 1970-1-1, but not to blank. Any ideas?

  • Virtual String Tree - Display subnode when parent node is hidden

    - by daemon_x
    Is there a way to show subnode if the parent node is hidden in the Virtual String Tree ? I have some tasks in the tree structure and I wish to display only tasks which belongs to the current user as the list, but from all levels. What I've done is the function to display a list, which hides tree buttons, tree lines, sets the fixed indent and enable toShowHiddenNodes option. Then in this function I iterate through the whole tree (all levels) and hide nodes which doesn't belong to the current user IsVisible[Node] := False and show those which belongs him IsVisible[Node] := True, but the subnodes which should be displayed are invisible when their parent is hidden. VT.TreeOptions.PaintOptions - toShowButtons - toShowTreeLines + toFixedIndent + toShowHiddenNodes

  • Passing GPS speed via the Eclipse Emulator Control

    - by Nick
    Hi, my app queries the GPS-speed using .getSpeed() on a LocationListener. Is there a way to set this speed using the Eclipse Emulator Control or the command line? I tried to feed multiple sets of coordinates to the emulator via the manual GPS-control, but it didn't pick up a speed from that. Also, using a pre-defined GPX-file and playing it doesn't work for me. I would like to test my app without having to take it on a test-drive in my car every time ;)! Thanks!

  • In XHR, is it possible to distinguish network errors from cross-origin errors?

    - by greim
    http://www.w3.org/TR/access-control/ Reading the CORS spec linked above, it seems to be the case that it's impossible to reliably distinguish between a generic "network error" and a cross-origin access denied error. From the spec: If there is a network error Apply the network error steps. Perform a resource sharing check. If it returns fail, apply the network error steps. http://www.w3.org/TR/access-control/#simple-cross-origin-request0 In my testing, I couldn't locate any features of Firefox's implementation that seem to indicate that the resource sharing check definitely failed. It just switches readyState to 4 and sets status to 0. Ultimately I'd like the ability to pass a success callback, a general fail callback, and an optional cross-origin fail callback, to my function. Thanks for any help or insight.

  • Are these REST HTTP response codes right, and what about the Content-Type?

    - by talentedmrjones
    I'm writing a controller helper that sets the proper response headers for my REST controller action. It's pasted below and should be simplified enough for those who aren't familiar with Zend Framework to understand what I'm doing. My question is: Are these codes correct for their respective responses, and in the case of "access denied" do I use a 401 or 403? Also, in case of responding with an error, I understand I should be placing a message in the response body, but should I set the "Content-Type" to "text/plain"? <?php class App_Controller_Helper_RestResponse extends Zend_Controller_Action_Helper_Abstract { public function denied() { // 403 or 401? } public function notFound() { // 404 } public function created() { // 201 } public function deleted() { // 204 } public function redirect() { // 301 // new url } public function malformed() { // 400 } public function gone() { // 410 } }

  • Caching result of SELECT statement for reuse in multiple queries

    - by Andrew
    I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.

  • enumerate all combinations in c++

    - by BCS
    My question is similar to this combinations question but in my case I have N (N 4) small sets (1-2 items per set for now might go to 3 maybe 4) and want to generate each combination of one item from each set. The current solution looks somethinging along the lines of this for(T:: iterator a = setA.begin(); a != setA.end(); ++a) for(T:: iterator b = setB.begin(); b != setB.end(); ++b) for(T:: iterator c = setC.begin(); c != setC.end(); ++c) for(T:: iterator d = setD.begin(); d != setD.end(); ++d) for(T:: iterator e = setE.begin(); e != setE.end(); ++e) something(*a,*b,*c,*d,*e); Simple, effective, probably reasonably efficient, but ugly and not very extensible. Does anyone know of a better/cleaner way to do this?

  • Check constraint on table lookup

    - by bzamfir
    Hi, I have a table, department , with several bit fields to indicate department types One is Warehouse (when true, indicate the department is warehouse) And I have another table, ManagersForWarehouses with following structure: ID autoinc WarehouseID int (foreign key reference DepartmentID from departments) ManagerID int (foreign key reference EmployeeID from employees) StartDate EndDate To set new manager for warehouse, I insert in this table with EndDate null, and I have a trigger that sets EndDate for previous record for that warehouse = StartDate for new manager, so a single manager appears for a warehouse at a certain time. I want to add two check constraints as follows, but not sure how to do this do not allow to insert into ManagersForWarehouses if WarehouseID is not marked as warehouse Do not allow to uncheck Warehouse if there are records in ManagersForWarehouses Thanks

  • What approach should be suitable for user authentification in simle client/server app

    - by TerryS
    My previous question was closed so I will be more specific. I need to create an application, desktop one written in C#, that will ask for user credentials and after verification opens the GUI allowing to work with DB (black box for users). It should be used from everywhere, not LAN or SQL domain. I assume I would need to do the following: Create a client and a server applications that will deal with authentification. That would mean a lot of socketing stuff.. Once the user is verified, the client queries would be sent to database (client-server-DB). The server would need to send the DB data sets back to the client. As you can see, this is just my guess but I have no idea whether its too complicated or completely wrong. The main thing is that it must be desktop app (not web based one) and accessible from everywhere. I am interested in main points how to design the system and will be extremely grateful for that.

  • For each level of factor aggregate values over all levels except the current one (in R)

    - by Andrey Chetverikov
    For each level of factor I need to extract values aggregated over all subsets of data.frame except the current one. For example, there is a several subjects doing a reaction time task during several days, and I need to compute mean reaction time for all subjects and all days, but not including the subject for whom the mean is computed. Currently, I do it like this: library(lme4) ddply(sleepstudy, .(Subject, Days), summarise , avg_rt=mean(sleepstudy[sleepstudy$Subject!=Subject&sleepstudy$Days==Days,"Reaction"]), .progress="text") It works fine for small data sets, but for large ones it can be very slow. Is there a way to do it faster?

  • vb express / visual studio - is it possible to run / debug one form only in a multi form application

    - by Luay
    hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

  • Writing string, numeric data to Excel via C# works, but Excel does not treat numeric data correctly

    - by Chapax
    Hi, I'm getting result sets from Sybase that I return to a C# client. I use the below function to write the result set data to Excel: ***private static void WriteData(Excel.Worksheet worksheet, string cellRef, ref string[,] data) { Excel.Range range = worksheet.get_Range(cellRef, Missing.Value); if (data.GetLength(0) != 0) { range = range.get_Resize(data.GetLength(0), data.GetLength(1)); range.set_Value(Missing.Value, data); } }* The data gets written correctly. The issue is that since I'm using string array to write data (which is a mixture of strings and floats), Excel highlights every cell that contains numeric data with the message "Number Stored as Text". How do I get rid of this issue? Many thanks, Chapax

  • what is the underlying data structure of a set c++?

    - by zebraman
    I would like to know how a set is implemented in C++. If I were to implement my own set container without using the STL provided container, what would be the best way to go about this task? I understand STL sets are based on the abstract data structure of a binary search tree. So what is the underlying data structure? An array? Also, how does insert() work for a set? How does the set check whether an element already exists in it? I read on wikipedia that another way to implement a set is with a hash table. How would this work?

  • Mock Objects properties not changing

    - by frictionlesspulley
    I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

  • UIActionsSheet text shadow problem

    - by AlexVogel
    I have a problem with the text shadow of the UIActionSheet buttons. At iOS 4.0.2 long string were truncated automatically. No at iOS 4.2 these texts are presented with a smaller font. But now the offset of the shadow is corrupted and to big. Is there a possibility to change/remove the text shadow of the UIActionSheet. EDIT: I'm building the UIActionSheet not with initWithTitle:, but with the normal init and sets all needed properties afterwards because the number of possible buttons is dynamic and the texts cannot be change. I've tested it with initWithTitle: and got the same results.

  • Best approach to synchronising properties across threads

    - by user290796
    Hi, I'm looking for some advice on the best approach to synchronising access to properties of an object in C++. The application has an internal cache of objects which have 10 properties. These objects are to be requested in sets which can then have their properties modified and be re-saved. They can be accessed by 2-4 threads at any given time but access is not intense so my options are: Lock the property accessors for each object using a critical section. This means lots of critical sections - one for each object. Return copies of the objects when requested and have an update function which locks a single critical section to update the object properties when appropriate. I think option 2 seems the most efficient but I just want to see if I'm missing a hidden 3rd option which would be more appropriate. Thanks, J

  • ASP.NET MVC Access model data in masterpage

    - by Paul
    I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

  • Best way to have unique key over 500M varchar(255) records in mysql/innodb?

    - by taw
    I have url column with unique key over it - but its performance on updates is absolutely atrocious. I suspect that's because the index doesn't all fit in memory. So I was thinking, how about adding a column of md5(url) with 16 bytes of binary data and unique-keying that instead. What would be the best datatype for that? I'd love to be able to just see 32-character hex hash, while mysql would convert it to/from 16 binary bytes and index that, as programs using the database might have some troubles with arbitrary binary data that I'd rather avoid if possible (also I'm a bit afraid that mysql might get some strange ideas about character sets and for example overalocating storage for that by 3:1 because it thinks it might need utf8, how do I avoid that for cure?).

  • Specifying routes by subdomain in Express using vhost middleware

    - by user730569
    I'm using the vhost express/connect middleware and I'm a bit confused as to how it should be used. I want to have one set of routes apply to hosts with subdomains, and another set to apply for hosts without subdomains. In my app.js file, I have var app = express.createServer(); app.use...(middlware)... app.use(express.vhost('*.host', require('./domain_routing')("yes")); app.use(express.vhost('host', require('./domain_routing')("no")); app.use...(middlware)... app.listen(8000); and then in domain_routing.js: module.exports = function(subdomain){ var app = express.createServer(); require('./routes')(app, subdomain); return app; } and then in routes.js I plan to run sets of routes, dependent on the subdomain variable passed in is "yes" or "no". Am I on the right track or is this not how you use this middleware?

  • New records added to DataGridView aren't displayed

    - by Ross
    I have a custom Order class, groups of which are stored in List<Order> and a DataGridView. I think the problem is in my implementation so here's how I'm using it: In the form enclosing DataGridView (as OrdersDataGrid): public partial class MainForm : Form { public static List<Order> Orders; public MainForm() { // code to populate Orders with values, otherwise sets Orders to new List<Order>(); OrdersDataGrid.DataSource = Orders; } Then in another form that adds an Order: // Save event public void Save(object sender, EventArgs e) { Order order = BuildOrder(); // method that constructs an order object from form data MainForm.Orders.Add(order); } From what I can tell from the console this is added successfully. I thought the DataGrid would be updated automatically after this since Orders has changed - is there something I'm missing? The DataGrid accepts the class since it generates columns from the members.

  • HABTM checking for match of latest 3

    - by user333614
    Here's an interesting one for you folks... I have a HABTM (has_and_belongs_to_many) relationship between "Dogs" and "Trips". My goal is to find two result sets: 1) Dogs that have been on at least 1 of the last 3 trips and call that @dogs_current 2) Dogs that have NOT been on any of the last 3 trips and call that @dogs_old I found that I can find what the last 3 trips are by doing this in the Trip model: named_scope :last3, :order => 'date DESC', :limit => 3 But not sure how to use that list get 1 and 2. This hack works, but it seems ugly. There must be a better way! :) @dogs_current = [] @dogs_old = [] @dogs.each do |dog| if (Trip.last3 - dog.trips).size < 3 then @dogs_current << dog else @dogs_old << dog end end Any ideas? Thanks! -Cam

  • How to represent a list of points in R

    - by Guido
    I am working with a large list of points (each point has three dimensions x,y,z). I am pretty new with R, so I would like to know what is the best way to represent that kind of information. As far as I know, an array allows me to represent any multidimensional data, so currently I am using: > points<-array( c(1,2,0,1,3,0,2,4,0,2,5,0,2,7,0,3,8,0), dim=c(3,6) ) > points [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1 1 2 2 2 3 -- x dim [2,] 2 3 4 5 7 8 -- y dim [3,] 0 0 0 0 0 0 -- z dim The aim is to perform some computations to calculate the euclidean distance between two sets of points (any hint in this sense would also be highly appreciated)

  • Is there a way to force CoreImage to use the GPU?

    - by NSSplendid
    We are having the following problem: a series of Core Image filters runs constantly in our program. When evaluating on my Macbook Pro, Core Image decides to schedule all graphics computation on the GPU, as expected. When using a MacPro, however, CI uses the CPUs! This is a problem, as we need them for other processing. [1] The question now is: Can one tell CI to run exclusively on the GPU? [1] Both hardware sets are of the newest kind. The MacPro has 8 Cores.
