  • UINavigationController inside UINavigationController view issue

    - by HurkNburkS
    I have two navigationcontrollers a main one and a sub one. The sub one is displaying inside the main one, which I am also hiding its navigationbar. as a result I am having some weird issues (things inside the view are being pushed down exactly the height of the navigationbar i am hiding) with the stuff I am displaying on the inside of the sub navigationcontroller. it looks like this. The left view is what I am doing in interface builder and the resulting view in the simulator. any help would be greatly appreciated. UPDATE: Here is the view with the subnav bar turned on so you can see the structure of my view. and here is the same view with the subnav turned off... can you see how the A is still sitting lower than it should be.. wel I think its because of the main navbar now as the whole subnavbar sits inside this view.. Last update that shows whats missing from the view

  • Microsoft Sync Framework with Mutliple Client and Server Database

    - by David Osborn
    I'm working on changes to an application to have a local data store instead of connecting directly to the database server. The client app will then sync changes both ways between the server database and its local data store. I'm trying to implement the syncing solution using Microsoft Sync Framework. To be clear there is no server application, only the database server, but there are multiple clients. I have started implementing two classes that implement FullEnumerationSimpleSyncProvider, one called LocalSyncProvider and one called ServerSyncProvider. The LocalSyncProvider knows how to enumerate, insert, update, delete items from the local data store, and the ServerSyncProvider knows how to enumerate, insert, update, delete items from the database server. They each use the provided SqlMetadataStore and store the two metadata stores (one for the local and one for the server) on the local drive of the client. This means that each client will have its own metadata store for its local data store and its own metadata store for the server database. Is this actually going to work, does there need to exists only one server metadata store, or do I need to be using the Sync Framework differently?

  • jqgrid not updating data on reload

    - by meepmeep
    I have a jqgrid with data loading from an xml stream (handled by django 1.1.1): jQuery(document).ready(function(){ jQuery("#list").jqGrid({ url:'/downtime/list_xml/', datatype: 'xml', mtype: 'GET', postData:{site:1,date_start:document.getElementById('datepicker_start').value,date_end:document.getElementById('datepicker_end').value}, colNames:[...], colModel :[...], pager: '#pager', rowNum: 25, rowList:[10,25,50], viewrecords: true, height: 500, caption: 'Click on column headers to reorder' }); $("#grid_reload").click(function(){ $("#list").trigger("reloadGrid"); }); $("#tabs").tabs(); $("#datepicker_start").datepicker({dateFormat: 'yy-mm-dd'}); $("#datepicker_end").datepicker({dateFormat: 'yy-mm-dd'}); ... And the html elements: <th>Start Date:</th> <td><input id="datepicker_start" type="text" value="2009-12-01"></input></td> <th>End Date:</th> <td><input id="datepicker_end" type="text" value="2009-12-03"></input></td> <td><input id="grid_reload" type="submit" value="load" /></td> When I click the grid_reload button, the grid reloads, but when it has done so it shows exactly the same data as before, even though the xml is tested to return different data for different timestamps. I have checked using alert(document.getElementById('datepicker_start').value) that the values in the date inputs are passed correctly when the reload event is triggered. Any ideas why the data doesn't update? A caching or browser issue perhaps?

  • Django app that can provide user friendly, multiple / mass file upload functionality to other apps

    - by hopla
    Hi, I'm going to be honest: this is a question I asked on the Django-Users mailinglist last week. Since I didn't get any replies there yet, I'm reposting it on Stack Overflow in the hope that it gets more attention here. I want to create an app that makes it easy to do user friendly, multiple / mass file upload in your own apps. With user friendly I mean upload like Gmail, Flickr, ... where the user can select multiple files at once in the browse file dialog. The files are then uploaded sequentially or in parallel and a nice overview of the selected files is shown on the page with a progress bar next to them. A 'Cancel' upload button is also a possible option. All that niceness is usually solved by using a Flash object. Complete solutions are out there for the client side, like: SWFUpload http://swfupload.org/ , FancyUpload http://digitarald.de/project/fancyupload/ , YUI 2 Uploader http://developer.yahoo.com/yui/uploader/ and probably many more. Ofcourse the trick is getting those solutions integrated in your project. Especially in a framework like Django, double so if you want it to be reusable. So, I have a few ideas, but I'm neither an expert on Django nor on Flash based upload solutions. I'll share my ideas here in the hope of getting some feedback from more knowledgeable and experienced people. (Or even just some 'I want this too!' replies :) ) You will notice that I make a few assumptions: this is to keep the (initial) scope of the application under control. These assumptions are of course debatable: All right, my idea's so far: If you want to mass upload multiple files, you are going to have a model to contain each file in. I.e. the model will contain one FileField or one ImageField. Models with multiple (but ofcourse finite) amount of FileFields/ ImageFields are not in need of easy mass uploading imho: if you have a model with 100 FileFields you are doing something wrong :) Examples where you would want my envisioned kind of mass upload: An app that has just one model 'Brochure' with a file field, a title field (dynamically created from the filename) and a date_added field. A photo gallery app with models 'Gallery' and 'Photo'. You pick a Gallery to add pictures to, upload the pictures and new Photo objects are created and foreign keys set to the chosen Gallery. It would be nice to be able to configure or extend the app for your favorite Flash upload solution. We can pick one of the three above as a default, but implement the app so that people can easily add additional implementations (kinda like Django can use multiple databases). Let it be agnostic to any particular client side solution. If we need to pick one to start with, maybe pick the one with the smallest footprint? (smallest download of client side stuff) The Flash based solutions asynchronously (and either sequentially or in parallel) POST the files to a url. I suggest that url to be local to our generic app (so it's the same for every app where you use our app in). That url will go to a view provided by our generic app. The view will do the following: create a new model instance, add the file, OPTIONALLY DO EXTRA STUFF and save the instance. DO EXTRA STUFF is code that the app that uses our app wants to run. It doesn't have to provide any extra code, if the model has just a FileField/ImageField the standard view code will do the job. But most app will want to do extra stuff I think, like filling in the other fields: title, date_added, foreignkeys, manytomany, ... I have not yet thought about a mechanism for DO EXTRA STUFF. Just wrapping the generic app view came to mind, but that is not developer friendly, since you would have to write your own url pattern and your own view. Then you have to tell the Flash solutions to use a new url etc... I think something like signals could be used here? Forms/Admin: I'm still very sketchy on how all this could best be integrated in the Admin or generic Django forms/widgets/... (and this is were my lack of Django experience shows): In the case of the Gallery/Photo app: You could provide a mass Photo upload widget on the Gallery detail form. But what if the Gallery instance is not saved yet? The file upload view won't be able to set the foreignkeys on the Photo instances. I see that the auth app, when you create a user, first asks for username and password and only then provides you with a bigger form to fill in emailadres, pick roles etc. We could do something like that. In the case of an app with just one model: How do you provide a form in the Django admin to do your mass upload? You can't do it with the detail form of your model, that's just for one model instance. There's probably dozens more questions that need to be answered before I can even start on this app. So please tell me what you think! Give me input! What do you like? What not? What would you do different? Is this idea solid? Where is it not? Thank you!

  • C# sendkeys problem

    - by user203123
    THe code below I copied from MSDN with a bit of modification: [DllImport("user32.dll", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName,string lpWindowName); DllImport("User32")] public static extern bool SetForegroundWindow(IntPtr hWnd); int cnt = 0; private void button1_Click(object sender, EventArgs e) { IntPtr calculatorHandle = FindWindow("Notepad", "Untitled - Notepad"); if (calculatorHandle == IntPtr.Zero) { MessageBox.Show("Calculator is not running."); return; } SetForegroundWindow(calculatorHandle); SendKeys.SendWait(cnt.ToString()); SendKeys.SendWait("{ENTER}"); cnt++; SendKeys.Flush(); System.Threading.Thread.Sleep(1000); } The problem is the number sequence in Notepad is not continuously. The first click always results 0 (as expected). but from the second click, the result is unpredictable (but the sequence is still in order, e.g. 3, 4, 5, 10, 14, 15, ....) If I click the button fast enough, I was able to get the result in continuous order (0,1,2,3,4,....) but sometimes it produces more than 2 same numbers (e.g. 0,1,2,3,3,3,4,5,6,6,6,7,8,9,...) Couldn't understand. Plz enlighten me :) Thanks.

  • Iphone application crashes when poping to rootController of UITabBar tab

    - by sniurkst
    Hello, I'm having this bug I can't figure out and it is making my head hurt. So, basically, in my iphone application I have UITabBar with some tabs each having UINavigationControllers inside. Something like this: someViewController *someController = [[someViewController alloc] myInit]; UINavigationController *someNav = [[UINavigationController alloc] initWithRootViewController:someController]; tab = [[UITabBarController alloc] init]; tab.viewControllers = [NSArray arrayWithObjects:otherNav, otherNav, evilNav, nil]; [window addSubview:tab.view]; So to reproduce my "precious" bug I go like this: click evilNav tab -> push tableListView (category list) -> push otherTableListView (category items list) -> push someOtherView (single item) -> popToRoot || popToController withindex:0 || click on evilNav tab again || pop to otherTableListView -> pop to tableListView -> crash (with no notable error) So if I go so far to someOtherView I can't go back to first tableListView (rootViewController) without application crashing. Meanwhile I can go to other tabs and then even click evilNav (when it is in otherTableListView or someOtherView state) without crashing. What could be causing this problem? (If you need I will post more code)

  • Storing Objects in columns using Hibernate JPA

    - by user210791
    Is it possible to store something like the following using only one table? Right now, what hibernate will do is create two tables, one for Families and one for people. I would like for the familymembers object to be serialized into the column in the database. @Entity(name = "family") class Family{ private final List<Person> familyMembers; } class Person{ String firstName, lastName; int age; }

  • Core Data Model Design Question - Changing "Live" Objects also Changes Saved Objects

    - by mwt
    I'm working on my first Core Data project (on iPhone) and am really liking it. Core Data is cool stuff. I am, however, running into a design difficulty that I'm not sure how to solve, although I imagine it's a fairly common situation. It concerns the data model. For the sake of clarity, I'll use an imaginary football game app as an example to illustrate my question. Say that there are NSMO's called Downs and Plays. Plays function like templates to be used by Downs. The user creates Plays (for example, Bootleg, Button Hook, Slant Route, Sweep, etc.) and fills in the various properties. Plays have a to-many relationship with Downs. For each Down, the user decides which Play to use. When the Down is executed, it uses the Play as its template. After each down is run, it is stored in history. The program remembers all the Downs ever played. So far, so good. This is all working fine. The question I have concerns what happens when the user wants to change the details of a Play. Let's say it originally involved a pass to the left, but the user now wants it to be a pass to the right. Making that change, however, not only affects all the future executions of that Play, but also changes the details of the Plays stored in history. The record of Downs gets "polluted," in effect, because the Play template has been changed. I have been rolling around several possible fixes to this situation, but I imagine the geniuses of SO know much more about how to handle this than I do. Still, the potential fixes I've come up with are: 1) "Versioning" of Plays. Each change to a Play template actually creates a new, separate Play object with the same name (as far as the user can tell). Underneath the hood, however, it is actually a different Play. This would work, AFAICT, but seems like it could potentially lead to a wild proliferation of Play objects, esp. if the user keeps switching back and forth between several versions of the same Play (creating object after object each time the user switches). Yes, the app could check for pre-existing, identical Plays, but... it just seems like a mess. 2) Have Downs, upon saving, record the details of the Play they used, but not as a Play object. This just seems ridiculous, given that the Play object is there to hold those just those details. 3) Recognize that Play objects are actually fulfilling 2 functions: one to be a template for a Down, and the other to record what template was used. These 2 functions have a different relationship with a Down. The first (template) has a to-many relationship. But the second (record) has a one-to-one relationship. This would mean creating a second object, something like "Play-Template" which would retain the to-many relationship with Downs. Play objects would get reconfigured to have a one-to-one relationship with Downs. A Down would use a Play-Template object for execution, but use the new kind of Play object to store what template was used. It is this change from a to-many relationship to a one-to-one relationship that represents the crux of the problem. Even writing this question out has helped me get clearer. I think something like solution 3 is the answer. However if anyone has a better idea or even just a confirmation that I'm on the right track, that would be helpful. (Remember, I'm not really making a football game, it's just faster/easier to use a metaphor everyone understands.) Thanks.

  • TypeError: can't convert String into Integer

    - by demas
    I have code: class Scene def initialize(number) @number = number end attr_reader :number end scenes = [Scene.new("one"), Scene.new("one"), Scene.new("two"), Scene.new("one")] groups = scenes.inject({}) do |new_hash, scene| new_hash[scene.number] = [] if new_hash[scene.number].nil? new_hash[scene.number] << scene end When I'm lauching it I get error: freq.rb:11:in `[]': can't convert String into Integer (TypeError) from freq.rb:11:in `block in <main>' from freq.rb:10:in `each' from freq.rb:10:in `inject' from freq.rb:10:in `<main>' If I change scenes to: scenes = [Scene.new(1), Scene.new(1), Scene.new(2), Scene.new(1)] the problem dissapear. Why I get error message in the first case? Why Ruby decide to convert scene.number from String to Integer? And one additional question about the 'inject' method. When Ruby initialize the 'new_hash' variable and how can Ruby know the type of this variable?

  • Jquery animation callback issues

    - by ChrisOPeterson
    I'm trying to build a simple carousel animation with jQuery. There are 3 viewable images at any one time with buttons to click on each side to go forward or backwards. The center image is raised up by 30px to be given prominence. When one of the buttons is pushed the center image should drop down then all three images move together left or right. The initial up and down animation works but on a callback none of the other animations will work. If I hard code the direction into them only one of them works. Is there something wrong with my current code or approach? ctr_right.click(function() { carouselAnimate("right") }); ctr_left.click(function() { carouselAnimate("left") }); function carouselAnimate(direction) { var offset = img_width + img_offset; img_focus.animate({"top": "+="+focus_offset}, "slow", function() { img_left.animate({direction: "-="+offset}, "slow"); img_focus.animate({direction: "-="+offset}, "slow"); img_right.animate({direction: "-="+offset}, "slow"); }); };

  • jQuery not and classes

    - by Giles B
    Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles

  • Using SqlBulkCopy in a multithread scenario with ThreadPool issue

    - by Ruben F.
    Hi. I'm facing a dilemma (!). In a first scenario, i implemented a solution that replicates data from one data base to another using SQLBulkCopy synchronously and i had no problem at all. Now, using ThreadPool, i implemented the same in a assynchronously scenario, a thread per table, and all works fine, but past some time (usualy 1hour because the operations of copy takes about the same time), the operations sended to the ThreadPool stop being executed. There are one diferent SQLBulkCopy using one diferent SQLConnection per thread. I already see the number of free threads, and they are all free at the begining of the invocation...I have one AutoResetEvent to wait that the threads finish their job before launching again, and a Semaphore FIFO that hold the counter of active threads. There are some issue that I have forgotten or that I should avaliate when using SqlBulkCopy? I apreciate some help, because my ideas are over;) Thanks

  • SQL Max Group By Query Help

    - by Hcabnettek
    Hi All, I have a quick question. How do I select the two values I need in one query? Currently I'm doing this, which works fine, but it's obviously running two queries when one should do the trick. I tried MAX(columnA) and GROUP BY ColumnB, but that returns multiple row. I only want one row returned. DECLARE @biID bigint , @dtThreshold DateTime SELECT @biID = MAX(biID) FROM tbPricingCalculationCount WITH (NOLOCK) SELECT @dtThreshold = dtDateTime FROM tbPricingCalculationCount WITH (NOLOCK) WHERE biID = @biID I would like both those variables to be set correctly in one query. How can I do that? Thanks, ~ck

  • The relationship between OPC and DCOM

    - by typoknig
    Hi all, I am trying to grasp the link between OPC and DCOM. I have watched all four of the tutorials here and I think I have a good feeling for what OPC is, but in one of the tutorials (the third one 35 seconds in) the narrator states that OPC is based on DCOM, but I do not understand how the two are really linked. My confusion comes from a question my professor posed in which he asked "How and where would you deploy OPC instead of DCOM and vice-versa." His question makes it seem like the two are not as linked as my research suggests. I'm not looking for anyone to answer the question, I just want to know the relation between OPC and DCOM, then I can figure the rest out. Specifically I would like to know if: 1.) One is always based on the other 2.) One can always be deployed without the other.

My RootLayout have one container control so any of element are child of this.HERETOFORE i want create one string that contain all general properties(not all of them) and save to DB, and when i load this control, i create an element by the type that i saved and affect it by the properties that i saved; with something like EXEC command. is this possible ? have you new approach for this scenario(Guide me with example please).
