  • MVP on Asp.Net WebForms

    - by Nicolas Irisarri
    I'm not clear about this.... When having a gridview on the View, is the controller who has to set up the Data source, columns, etc? or I just have to expose the DataBinding stuff, fire it from the controller and let the html/codebehind on the view handle all the rendering and wiring up? To be more precise: on the view should I have private GridView _gv public _IList<Poco> Source { get {_gv.DataSource;} set {_gv.DataSource = value; _gv.DataBind();} } Or should it be (from http://stackoverflow.com/questions/153222/mvp-pattern-passive-view-and-exposing-complex-types-through-iview-asp-net-web) private GridView _datasource; public DataSource { get { return _datasource; } set { _datasource = value; _datasource.DataBind(); } } Maybe I'm having it all wrong .... Where can I find an example that is not a "Hello world" example on MVP for ASP.Net???

  • Is recursion ever faster than looping?

    - by Carson Myers
    I know that recursion is sometimes a lot cleaner than looping, and I'm not asking anything about when I should use recursion over iteration, I know there are lots of questions about that already. What I'm asking is, is recursion ever faster than a loop? To me it seems like, you would always be able to refine a loop and get it to perform more quickly than a recursive function because the loop is absent constantly setting up new stack frames. I'm specifically looking for whether recursion is faster in applications where recursion is the right way to handle the data, such as in some sorting functions, in binary trees, etc.

  • IIS7 URL Rewrite with dynamic subdomains.

    - by arri.me
    My goal is to implement the following scheme using the subdomain and path as attributes: Use a wildcard DNS entry that routes any subdomain to the root site: Example: *.example.com ex: http://xyz.example.com to http://example.com Next I want to rewrite the requests to point to a specific page, passing both the subdomain and the request path as attributes. Example: http://xyz123.example.com/images/header.jpg to http://example.com/get.aspx?id=xyz123&path=/images/header.jpg I've seen several questions on here regarding similar goals, but not quite the same. I'm new to using rewrite rules, so any help is appreciated. I will update this as I make progress.

  • Tree View WIKI replacement solution for SharePoint like Confluence?

    - by Melih Öztürk
    Hi to all, I keep my Process Documents on SVN and I want to create a Wiki page includes the information about these files. We use SharePoint in the company for basic document sharing and team sites. As it is mentioned in http://stackoverflow.com/questions/256407/what-are-your-biggest-complaints-about-sharepoint SharePoint Wiki lacks of usability. I need an easy to use wiki tool which is capable of showing the content like WikiPedia contents and it would be great if I could have the SharePoint tree view and Active Directory authentication also. I googled it and found Atlassian's Confluence and it seems that this product is capable of the requirements. We use Jira for issue tracking, so we can use it's reporting in dashboards. I need and it has a Wiki part which displays wiki pages in tree view. It should be like Does anyone used Confluence or have an idea for other products which meets my requirements

  • REST api ambiguity and WADL

    - by JDonner
    I have a REST api that's ambiguous, something like (this isn't the specific problem, just gives an idea of the ambiguity): /toplevel/${customer_number}/some_command/more stuff /toplevel/${customer_number}/${some_product_name_anything_goes}/more stuff We've been getting away with it because our .htaccess file lists the more specific 'command' form before the general ${product_name} version, and the first match wins. Now though, we're writing a WADL, and, as you might expect, we're having trouble with our chosen tool consuming the WADL, because the API is ambiguous. My questions are: a) Does the WADL spec speak to whether they can validly represent ambiguous APIs? b) Tool support - in your experience, do tools choke on ambiguous WADLs? (if ambi. WADLs are allowed then those are weak tools but, you'd want to be on the safe side) c) Just any experience with ambiguous REST apis, most especially wrt WADLs, really. For the curious, here's the latest spec: As far as I can tell it doesn't specifically address this, I guess it really comes down to how tools handle it. Thanks.

  • python variable scope

    - by Oscar Reyes
    I'm teaching my self python and I was translating some sample class Student: def __init__( self, name, a,b,c ): self.name = name self.a = a self.b = b self.c = c def average(self): return ( a+b+c ) / 3.0 Which is pretty much my intended class definition Later in the main method I create an instance and call it a if __name__ == "__main__" : a = Student( "Oscar", 10, 10, 10 ) That's how I find out that the variable a declared in main is available to the method average and that to make that method work , I have to type self.a + self.b + self.c instead What's the rationale of this? I found related questions, but I don't really know if they are about the same

  • IE8 and P3P problems again,

    - by MSolution
    Have been browsing across the net, and seems everyone who got into this mess, really slogged to get out of it,... and now my turn! http://stackoverflow.com/questions/999534/ie-p3p-iframe-and-blocked-cookies-works-until-page-host-page-has-personal-info been reading alot, and i have a very simple p3p policy here: http: // bit.ly/cCyGi5 and corresponding P3P compact policy: P3P: CP="COM DEM INT NAV OTC PRE PUR STA NOI DSP COR ADMi DEVi OUR BUS" I have validated my P3P policy via the validator at w3c, I have tried "privacy bird" IE extension, and it says my P3P.xml matches with my privacy settings, and has no conflict, my compact policy matches with my P3P policy, coz some where i read IE7 matches the two!!! If i lower my privacy settings in IE, the cookies get restricted, and if i further lower it to allow all, it gets thru, so it is my P3P compact policy the coz, and needs fixing. If someone can guide me in the right direction, or if i can hire someone for an hour or two to look into it. M.

  • HTML5 web storage: can different websites overwrite each other’s data on a user’s computer?

    - by Deepak Mahalingam
    I have a few questions regarding the concept of HTML5 storage. I went through the w3c specification, books and tutorials on the same, but still I am a bit unclear about certain concepts: Assume that I access Website A. Some JavaScript runs in my browser that sets a key value pair, say ('username','deepak'). Then I access Website B which also adds a key,value pair in the localstorage as ('username','mahalingam'). How will they both be differentiated? Will Website B override the value set by website A in my localstorage? How can we ensure that a website would not erase all of my localstorage?

  • Are TClientDataSets part of your toolkit, or have they been replaced by something else?

    - by Tom1952
    I have 50 or 60 records of four or five fields. I need to load the records into RAM (From a CSV file), search on different fields, enumerate, etc. Not a lot of data, not a lot of functionality. I was all excited to use the new (to me in D2010) TDictionary or TList, but thought that a TClientDataset (which I've never used before) might be more appropriate. With a TClientDataSet, I can use .Locate on any field, enumerate with while NOT CDS.EOF, etc. And, what exactly is this MidasLib that I have to use with CDS? Can I reasonably expect it to be supported in the future? Is TClientDataSet still considered state-of-the-art, or is it showing its age and somewhat deprecated (literally and figuratively)? I've seen colleagues use DX's TdxMemData. Why use it (or any of the other handful of memory datasets I've seen while googling this issue) rather than a CDS? Related question: http://stackoverflow.com/questions/274958/delphi-using-tclientdataset-as-an-in-memory-dataset

  • ASP.NET MVC How to convert ModelState errors to json

    - by JK
    How do you get a list of all ModelState error messages? I found this code to get all the keys: ( http://stackoverflow.com/questions/888521/returning-a-list-of-keys-with-modelstate-errors) var errorKeys = (from item in ModelState where item.Value.Errors.Any() select item.Key).ToList(); But how would I get the error messages as a IList or IQueryable? I could go: foreach (var key in errorKeys) { string msg = ModelState[error].Errors[0].ErrorMessage; errorList.Add(msg); } But thats doing it manually - surely there is a way to do it using LINQ? The .ErrorMessage property is so far down the chain that I don't know how to write the LINQ...

  • Why isn't TextBox.Text in WPF animatable?

    - by cplotts
    Ok, I have just run into something that is really catching me off-guard. I was helping a fellow developer with a couple of unrelated questions and in his project he was animating text into some TextBlock(s). So, I went back to my desk and recreated the project (in order to answer his questions), but I accidentally used TextBox instead of TextBlock. My text wasn't animating at all! (A lot of help, I was!) Eventually, I figured out that his xaml was using TextBlock and mine was using TextBox. What is interesting, is that Blend wasn't creating key frames when I was using TextBox. So, I got it to work in Blend using TextBlock(s) and then modified the xaml by hand, converting the TextBlock(s) into TextBox(es). When I ran the project, I got the following error: InvalidOperationException: '(0)' Storyboard.TargetProperty path contains nonanimatable property 'Text'. Well, it seems as if Blend was smart enough to know that ... and not generate the key frames in the animation (it would just modify the value directly on the TextBox). +1 for Blend. So, the question became: why isn't TextBox.Text animatable? The usual answer is that the particular property you are animating isn't a DependencyProperty. But, this isn't the case, TextBox.Text is a DependencyProperty. So, now I am bewildered! Why can't you animate TextBox.Text? Let me include some xaml to illustrate the problem. The following xaml works ... but uses TextBlock(s). <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="TextBoxTextQuestion.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480" > <Window.Resources> <Storyboard x:Key="animateTextStoryboard"> <StringAnimationUsingKeyFrames Storyboard.TargetProperty="(TextBlock.Text)" Storyboard.TargetName="textControl"> <DiscreteStringKeyFrame KeyTime="0:0:1" Value="Goodbye"/> </StringAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Window.Triggers> <EventTrigger RoutedEvent="FrameworkElement.Loaded"> <BeginStoryboard Storyboard="{StaticResource animateTextStoryboard}"/> </EventTrigger> </Window.Triggers> <Grid x:Name="LayoutRoot"> <StackPanel Orientation="Vertical" HorizontalAlignment="Center" VerticalAlignment="Center"> <TextBlock x:Name="textControl" Text="Hello" FontFamily="Calibri" FontSize="32"/> <TextBlock Text="World!"

  • How do I use waf to build a shared library?

    - by James Morris
    I want to build a shared library using waf as it looks much easier and less cluttered than GNU autotools. I actually have several questions so far related to the wscript I've started to write: VERSION='0.0.1' APPNAME='libmylib' srcdir = '.' blddir = 'build' def set_options(opt): opt.tool_options('compiler_cc') pass def configure(conf): conf.check_tool('compiler_cc') conf.env.append_value('CCFLAGS', '-std=gnu99 -Wall -pedantic -ggdb') def build(bld): bld.new_task_gen( features = 'cc cshlib', source = '*.c', target='libmylib') The line containing source = '*.c' does not work. Must I specify each and every .c file instead of using a wildcard? How can I enable a debug build for example (currently the wscript is using the debug builds CFLAGS, but I want to make this optional for the end user). It is planned for the library sources to be within a sub directory, and programs that use the lib each in their own sub directories.

  • Am i passing values or adresses? [Java]

    - by Samuel
    Hello World, I am new to java and i was asking myself, if i have a class 'Example' and somewhere i make a: Example example1 = new Example(); and i add some stuff to it, lets say example1.setExampleBoolean(false); and now i make: Example example2 = example1; example2.setExampleBoolean(true); Did i say with Example example2 = example1 let example2 point to the same adress as example1? Because than i would have altered example1. In other words would, using something like: Boolean exampleBoolean = example1.getExampleBoolean(); exampleBoolean be true of false? Might be a stupid questions but for me it would change the way i'd handle problems in my programs :) Thanks in advance -Samuel

  • TTPhotoViewController: Images not loading until swipe

    - by Raj
    Hi, I am trying to implement TTPhotoViewController in a sample iPad application. I have implemented properly TTPhotoSource and TTPhoto protocols. The TTPhotoViewController does show image, but not until swiped. The right and left button in the tab bar below doesnt seem to work at all, they never change the image displayed. The UIActivityIndicatorView is never put up, nor the right and left buttons are validated when last or first images are reached. I am initializing the subclass of TTPhotoViewController as a rootViewController of a UINavigationController object which I am adding it onto a view. This rules out the possibility of the problem faced here: http://three20.stackexchange.com/questions/78/ttphotoviewcontroller-not-loading-images-immediately What else am I missing? Anybody faced similar problems and found a way around? Thanks, Raj

  • Find Window At Location Using Carbon And Carbon Problems In 64-Bit Applications

    - by JxXx
    As I said in some questions today I´m looking for the way to get window or windowPart references at a certain location. Although I know I could use Cocoa for this purpose (I don´t know how to do it yet) I prefer (and probably need) to do this using Carbon because the entire application that needs this functionality is written in C++ but I´ve found many problems trying it. Does anyone get a valid windowPtr or windowRef using one of the following functions? FindWindow, MacFindWindow, HIWindowFindAtLocation or FindWindowOfClass I always get 0 as the windowRef or windowPtr that I´m looking for. What I´m doing wrong? Any ideas? It´s true that now if you want to create a 64-bit application for Mac OS X, you need to use Cocoa to implement its user interface because some APIs commonly used by Carbon applications are not available in 64-bit applications? Thank you. JxXx

  • VS2010 add-in custom menu item in files of Solution Explorer

    - by NewProgrammer
    Hey guys, I need to create a custom menu item for Visual Studio 2010 Add-in in C#, but I have had no luck in coming with a solution anytime soon. I am aware that there was a similar post: http://stackoverflow.com/questions/2486818/visual-studio-add-in-adding-a-context-menu-item-to-solution-explorer But it did not help, as the blog follows the process through the integration package, and the video is done through VB. I had attempted to convert the VB syntax to the C# syntax, but about half way through the video, the Add-in methods has significantly changed from 2005 to 2010, as some of the methods have removed or changed. Is there any good tutorials on making a custom menu item on the Solution Explorer in the lastest Visual Studio in C#, and is there a good website that could be used as a reference for looking over the VS add-in API? I've used Microsoft's main website, however it is confusing and wordy, which is difficult to understand and find the methods, properties, or commands that I am looking for. Any help would be appreicated, Thanks in advance.

  • django __search - trying to do x+y__search

    - by ckohrman
    I'm trying to do something like this with django: Q(x+y__search = z) I'm using __search to boolean search for a list of words within two separate lists (requiredTags, preferredTags). Line 10 is the one I have questions about. I want to see if the list of words (requTags) is found among requiredTags or preferredTags. requTags="" prefeTags="" for i in reqTags: if(i!=""): requTags+="+"+i+" " for i in prefTags: if(i!=""): prefeTags+=i+" " if(requTags!=""): query=query &( Q(requiredTags__search + preferredTags__search = requTags)) if(prefeTags!=""): query=query &( Q(requiredTags__search = prefeTags) | Q(preferredTags__search = prefeTags)) For instance: requTags might be: +beans +rice +cheese. requiredTags might be: beans,rice,tortilla preferredTags might be: cheese I didn't see any way to combine requiredTags and preferredTags in the documentation. Any help would be appreciated as I'm a beginner...

  • What is JDBC's Connection.isClosed() good for, and why is Snaq DBPool misbehaving on close?

    - by Uri
    I have the following code in Java: if(!conn.isClosed()) { conn.close(); } Instead of working, I am awarded with: java.sql.SQLException: Connection already closed My connection object is a Snaq.db.CacheConnection I checked the JavaDocs for isClosed, and they state that: This method generally cannot be called to determine whether a connection to a database is valid or invalid. A typical client can determine that a connection is invalid by catching any exceptions that might be thrown when an operation is attempted. So my questions are: 1) What good is JDBC's isClosed() anyway? Since when do we use Exceptions in Java to check for validity? 2) What is the correct pattern to close a database? Should I just close and swallow exceptions? 3) Any idea why would SnaqDB be closing the connection? (My backend is a Postgres 8.3)

  • Trapping Error Status in MSBuild

    - by Ruben Bartelink
    As part of some build automation of running xUnit.net tests with MSBuild, I'm running into a case where I need to loop over a batch of items. Inside the loop, I need to detect whether an iteration failed, but I want to continue executing regardless. Then after the batched bit, I need to know whether one or more errors have occurred in order to report the outcome to TeamBuild. IOW, in pseudocode: Task Name=RunTests CreateItems ForEach item CallTarget Target=RunTest ContinueOnError=true CombineNUnitResults Report success/failure Task Name=RunTest XUnit item I'm hoping this can be achieved without a custom task (or hacking the xunit.net MSBuild task as Jonne did). (But willing to use MSBuild Community or Sdc tasks) And @BradWilson: I this is isnt possible to do cleanly, I'll be looking for Jonne's change a la the NUnit task to also make it into the xunit task See also: http://stackoverflow.com/questions/517560/how-do-i-get-team-build-to-show-test-results-and-coverage-for-xunit-net-test-suit

  • Do Precompiled headers help with rebuilds?

    - by brickner
    I read some of the questions about precompiled headers but couldn't find a direct answer to that. I usually rebuild my entire Visual Studio 2010 solution. One of the projects in my solution is a C++/CLI project. I thought that using precompiled headers in that project will increase the speed of the compilation. After some experiments, it seems that using precompiled headers only slows the rebuild process. Do precompiled headers only help with builds that didn't completely clean the old files?

  • Database design - alternatives for Entity Attribute Value (EAV)

    - by Bob
    Hi, see http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters for similar topic. My question: i want to design a database, that will be used for a production facility of different types of products where each product has its own (number of) parameters. because i want the serial numbers to be in one tabel for overview purposes i have a problem with these different paraeters . One solution could be EAV, but it has its downsides, certainly because we have +- 5 products with every product +- 20.000 serial numbers (records). it looks a bit overkill to me... I just don't know how one could design a database so that you have an attribute in a mastertable that says: 'hey, you could find details of this record in THAT detail-table". 'in a way that you qould easely query the results) currenty i am using Visual Basic & Acces 2007. but i'm going to Visual Basic & MySQL. thanks for your help. Bob

  • Does it make sense to use a NSFetchedResultsController without an UITableViewController? How are the

    - by dontWatchMyProfile
    I mean... could I also just create a plain old UIViewController and then set up a UITableView myself, plus an NSFetchedResultsController? How much do UITableViewController and NSFetchedResultsController interact with eachother? As far as I see it, UITableViewController is NOT by default already adopting the NSFetchedResultsControllerDelegate protocol. It almost looks like if UITableViewController has been developed without knowing about NSFetchedResultsController. Probably they even did that before developing FRC. Anyways, just a raw guess because the UITableViewController lacks of mentioning FRC at all. So the only thing I see in UITableViewController is that it is already the delegate for a UITableView by adopting the protocol, and it sets up the UITableView instance for me and assigns it internally to it's tableView property. Is that the whole magic of UITableViewController? (note: the nsfetchedresultscontrolle tag is not a typo. SO has a limit for the num of chars...too bad for that missing r, that's why I avoided this tag in my other buch of questions like the plague)

  • Create new UIImage by adding shadow to existing UIImage

    - by Tom Irving
    I've taken a look at this question: http://stackoverflow.com/questions/962827/uiimage-shadow But the accepted answer didn't work for me. What I'm trying to do is take a UIImage and add a shadow to it, then return a whole new UIImage, shadow and all. This is what I'm trying: - (UIImage*)imageWithShadow { CGColorSpaceRef colourSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef shadowContext = CGBitmapContextCreate(NULL, self.size.width, self.size.height + 1, CGImageGetBitsPerComponent(self.CGImage), 0, colourSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colourSpace); CGContextSetShadow(shadowContext, CGSizeMake(0, -1), 1); CGContextDrawImage(shadowContext, CGRectMake(0, 0, self.size.width, self.size.height), self.CGImage); CGImageRef shadowedCGImage = CGBitmapContextCreateImage(shadowContext); CGContextRelease(shadowContext); UIImage * shadowedImage = [UIImage imageWithCGImage:shadowedCGImage]; CGImageRelease(shadowedCGImage); return shadowedImage; } The result is that I get exactly the same image as before I put it through this method. I am doing this the correct way, or is there something obvious I'm missing?
