  • Can't read from aspnet_client folder for crystal reports

    - by Hank Allen
    I created a little ASP .Net app to run Crystal Reports. It runs fine from VS 2008 but not when deployed to IIS on Windows 7. The toolbar images are not rendered. The problem seems to be I can't read from the aspnet_client folder even though I've made into a virtual directory. I can't even read images I put in there just to see if the folder can be read from an ASP page. I also made sure the IIS user can read from there. I'm stumped.

  • NSString copy not copying?

    - by Scotty Allen
    NSString *myString = @"sample string"; NSString *newString = [NSString stringWithString: myString]; If I set a breakpoint after these two lines, the pointer for myString is the same as the pointer for newString. WTF? Isn't NSString copy supposed to return a pointer to a new object? Or am I missing something fundamental about how copy is supposed to work?

  • Why am I losing sessions when running in StateServer mode?

    - by Nick Allen - Tungle139
    I have checked the servers (Win Server 2003) application event logs for the following problem http://support.microsoft.com/kb/308097 which doesn't show up. It just appears that sessions drop randomly for random users It's a single server setup, no web farms and no load balancing Even though the issue I point to above doesn't occur in the logs, is it worth increasing the stateNetworkTimeout attribute anyway? The configuration at the moment is simply <sessionState mode="StateServer" cookieless="false" stateConnectionString="tcpip=localhost:42424" timeout="60"/>

  • WPF 4.0 Font Rendering Issue

    - by Tom Allen
    I'm getting a weird rendering issue with WPF 4 applications in the way they render some of the text as it's stretching it and making it very narrow. .net 3.5: .net 4.0: At first I thought it could be a problem with the font, but I'm also seeing the same problem in the Blend 4 beta: I'm running XP SP3, Visual Studio 2010 Professional and everything's as up to date as it can be. I'm not noticing any such problems with Silverlight 4 apps I have built on the same machine... Anyone else seen this or know why it's happening?

  • SIMPLE PHP MVC Framework!

    - by Allen
    I need a simple and basic MVC example to get me started. I dont want to use any of the available packaged frameworks. I am in need of a simple example of a simple PHP MVC framework that would allow, at most, the basic creation of a simple multi-page site. I am asking for a simple example because I learn best from simple real world examples. Big popular frameworks (such as code ignighter) are to much for me to even try to understand and any other "simple" example I have found are not well explained or seem a little sketchy in general. I should add that most examples of simple MVC frameworks I see use mod_rewrite (for URL routing) or some other Apache-only method. I run PHP on IIS. I need to be able to understand a basic MVC framework, so that I could develop my own that would allow me to easily extend functionality with classes. I am at the point where I understand basic design patterns and MVC pretty well. I understand them in theory, but when it comes down to actually building a real world, simple, well designed MVC framework in PHP, i'm stuck. I would really appreciate some help! Edit: I just want to note that I am looking for a simple example that an experienced programmer could whip up in under an hour. I mean simple as in bare bones simple. I dont want to use any huge frameworks, I am trying to roll my own. I need a decent SIMPLE example to get me going.

  • Should we develop a custom membership provider in this case?

    - by Allen
    I'll be adding a bounty to this, probably 200, more if you guys think its appropriate. I wont accept an answer until I can add a bounty so feel free to go ahead and answer now Summary Long story short, we've been tasked with gutting the authentication and authorization parts of a fairly old and bloated asp.net application that previously had all of these components written from scratch. Since our application isn't a typical one, and none of us have experience in asp.net's built in membership provider stuff, we're not sure if we should roll our own authentication and authorization again or if we should try to work within the asp.net membership provider mindset and develop our own membership provider. Our Application We have a fairly old asp.net application that gets installed at customer locations to service clients on a LAN. Admins create users (users do not sign up) and depending on the install, we may have the software integrated with LDAP. Currently, the LDAP integration bulk-imports the users to our database and when they login, it authenticates against LDAP so we dont have to manage their passwords. Nothing amazing there. Admins can assign users to 1 group and they can change the authorization of that group to manage access to various parts of the software. Groups are maintained by Admins (web based UI) and as said earlier, granted / denied permissions to certain functionality within the application. All this was completely written from the ground up without using any of the built in .net authorization or authentication. We literally have IsLoggedIn() methods that check for login and redirect to our login page if they aren't. Our Rewrite We've been tasked to integrate more tightly with LDAP, they want us to tie groups in our application to groups (or whatever types of containers that LDAP uses) in LDAP so that when a customer opt's to use our LDAP integration, they dont have to manage their users in LDAP AND in our application. The new way, they will simply create users in LDAP, add them to Groups in LDAP and our application will see that they belong to the appropriate LDAP group and authenticate and authorize them. In addition, we've been granted the go ahead to completely rip out the User authentication and authorization code and completely re-do it. Our Problem The problem is that none of us have any experience with asp.net membership provider functionality. The little bit of exposure I have to it makes me worry that it was not intended to be used for an application such as ours. Though, developing our own ASP.NET Membership Provider and Role Manager sounds like it would be a great experience and most likely the appropriate thing to do. Basically, I'm looking for advice, should we be using the ASP.NET Membership provider & Role Management API or should we continue to roll our own? I know this decision will be influenced by our requirements so I'm going over them below Our Requirements Just a quick n dirty list Maintain the ability to have a db of users and authenticate them and give admins (only, not users) the ability to CRUD users Allow the site to integrate with LDAP, when this is chosen, they don't want any users stored in the DB, only the relationship between Groups as they exist in our app / db and the Groups/Containers as they exist in LDAP. .net 3.5 is being used (mix of asp.net webforms and asp.net mvc) Has to work in ASP.NET and ASP.NET MVC (shouldn't be a problem I'm guessing) This can't be user centric, administrators need to be the only ones that CRUD (or import via ldap) users and groups We have to be able to Auth via LDAP when its configured to do so I always try to monitor my questions closely so feel free to ask for more info. Also, as a general summary of what I'm looking for in an answer is just. "You should/shouldn't use xyz, here's why". Links regarding asp.net membership provider and role management stuff are very welcome, most of the stuff I'm finding is 5+ years old. Edit: Added some stuff to "Our Rewrite"

  • XmlDataProvider authentication Http issue

    - by Allen Ho
    Hi, I have an XMLDataProvider IsAsynchronous="True" x:Key="xmlData" Source="http://192.168.15.90/text.xml"/ The only problem is the Source requires authtication. I can get around this but using a HttpWebRequest in which I can pass in NetworkCredentials, but I was just wondering if there was a simpler way of passing in credentials to the XMLDataProvider

  • Silverlight: Set Items Widths in ItemsControl to Stretch

    - by Tom Allen
    I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl: I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits). I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked. Should be a straight forward one, but it's something I just can't quite figure out...

  • Missing taglibrary in Netbeans Hibernate tutorial xhtml file?

    - by Christopher W. Allen-Poole
    I just finished the Netbeans introduction to Hibernate tutorial ( http://netbeans.org/kb/docs/web/hibernate-webapp.html#01 ) and I am getting the following error: "This page calls for XML namespace declared with prefix br but no taglibrary exists" Now, I have seen a similar question somewhere else: http://forums.sun.com/thread.jspa?threadID=5430327 but the answer is not listed there. Or, if it is, then I am clearly missing it -- line one of my index.xhtml file reads "http://www.w3.org/1999/xhtml". It also does not explain why, when I reload localhost:8080, the message disappears.

  • Using string[] as a Dictionary key e.g. Dictionary<string[], StringBuilder>

    - by Nick Allen - Tungle139
    The structure I am trying to achieve is a composite Dictionary key which is item name and item displayname and the Dictionary value being the combination of n strings So I came up with var pages = new Dictionary<string[], StringBuilder>() { { new string[] { "food-and-drink", "Food & Drink" }, new StringBuilder() }, { new string[] { "activities-and-entertainment", "Activities & Entertainment" }, new StringBuilder() } }; foreach (var obj in my collection) { switch (obj.Page) { case "Food": case "Drink": pages["KEY"].Append("obj.PageValue"); break; ... } } The part I am having trouble with is accessing the Dictionary Key pages["KEY"] How do I target the Dictionary Key whose value at [0] == some value? Hope that makes sense

  • iPad UIColor Saturation Issues

    - by Carter Allen
    I am trying to draw a UIColor on the screen of a view-based app, and I am trying to do so using HSB. It is absolutely necessary for me to use HSB in this case. I can create a UIColor object with any S value from 0.0f to 0.75f, but past that the numerical changes have no effect on the actual saturation displayed. I need it to be 1.0f, but it is still using 0.75f. Any ideas on why it is doing that, and how I can make it work?

  • WPF Animation Duration

    - by Allen Ho
    I have a storyboard like the following Duration="0:0:1" Completed="DeviceExplorer_Completed" The animation for some reason does not appear to be working linearly. If I change the duration to something like Duration="0:0:0.8" and assign the stroyboard to a MouseEnter event of a button, the animation moves but does not complete for some reason, I move my mouse over the button a few times before it enetually completes... Any ideas why?

  • Object created in Interface Builder getting dealloc'ed too soon

    - by Collin Allen
    The Project I'm working on a relatively simple iPhone OS project that's navigation controller based, with a root table view and a detail table view. Tap an item in the main list to see its details in a pushed table view. The Setup I broke out the data source for both views into their own objects so as not to muddy the purpose of a view controller. Having done this, the table views no longer have data sources since those methods are now in separate files, so I created an instance of each data source class in the appropriate XIB files with the Object item (dragged it in, then set its class). Then, to actually connect the tableviews to their data sources, I set the dataSource outlet of each tableview to the yellow data source object in Interface Builder. The table view delegates are still set to their view controllers. The Problem The root table view works just fine, but when you tap a row to push to the detail view, the data source object gets instantiated as expected, then immediately dealloc'ed, causing a crash (numberOfSectionsInTableView: gets called on the freed object). I can't figure out why the data source is getting automatically dealloc-ed when I need it right then and there for the detail view, as indicated by my data source object creation and tableview connection in Interface Builder. What's more perplexing is that the very approach works fine for the root tableview! The Question Is there anything obvious I'm missing that would cause this to happen? Or, is this even the right way to instantiate a data source for a table view controller? It seems like poor object oriented programming to do it from within the view controller, which should only be concerned with the view. I could cram everything in two table view controller classes and it would probably work, but it would not be as modular as I'd like. Thanks!

  • Rewriting subdomain to subfolder with htaccess

    - by Owen Allen
    I'm attempting to use .htaccess in the root folder of an Ubuntu/Apache2 server in order to mask a subdomain to subfolder and I keep getting a 500 Internal Error. I know that I'm doing something stupidly wrong and it is some silly error causing the problem. I've checked all of the similar threads on SO and online and whenever I try their advice the 500 continues. Here's my code. RewriteEngine on RewriteCond %{HTTP_HOST} ^admin\.mydomain\.com.*$ RewriteRule (.*) intranet/$1 [L] What I want to occur is that if a user visits admin.mydomain.com they will get the contents of the folder admin.mydomain.com/intranet/ but their URL bar will still be admin.mydomain.com. Any idea what I'm doing wrong? In addition, some of the threads online talked about possible problems with this system. Is this the best way of doing this masking, should I be using a vhost setup?

  • iPhone tilt direction

    - by Tate Allen
    Hi all, I am making a simple, tilt controlled game using UIKit. So far, when I tilt the device the character moves in the appropriate direction. What I want him to do is to change the direction he is facing when I tilt the device. For example, when I tilt it left, I want the character to face left. Is there a way to detect whether the device was tilted left or right? If so, could you point me in the right direction please. Thanks, Tate

  • WPF Menu Items Styles

    - by Allen Ho
    Hi, I have an application resource of the following <Style TargetType="{x:Type TextBlock}"> <Setter Property="Background" Value="{DynamicResource windowTextBackColor}"/> <Setter Property="Foreground" Value="{DynamicResource windowsTextForeColor}"/> </Style> So all the text blocks in my application should assume those colours. However the Menu and its containing MenuItems on my Main Window does not take these colours? I have to do the XAML for it to assume those colours, Is there a reason why setting a style that targets Text blocks does not work? Thanks
