• Validating XML tag by tag

  - by Greatful

  Hi All I'm having some issues validating some XML against a Schema, using .net and C#. I am using XmlReaderSettings with the ValidationEventHandler. However, this seems to stop catching errors after it has encountered the first error at a particular level within the XML file, instead of checking the next tag at the same level, so basically it does not check each and every tag within the XML file instead skipping a level when it has found an error. I was hoping to get some advice from somebody who has successfully accomplished this type of validation. Thanks very much

• Having to keep on restarting the Application Pool?

  - by smclintock

  One of our major websites (built on PHP, MSSQL, IIS7) has started to become unresponsive every few hours and I'm having to log on to the server and restart the application pool. The rest of the websites on the server are fine, so I figure it may be due to a code problem? Whilst I look over all the code, specifically the database connections, would anyone have any advice on how I could better track this down to what is actually causing it to become unresponsive? By "unresponsive" I mean when you enter the URL it doesn't resolve and times out. Thanks for any help, Steven.

• Seam/Hibernate and PostgreSQL -- Any issues?

  - by Shadowman

  I'm currently working on a project that makes use of Seam/Hibernate (JPA) on MySQL. I'm reconsidering moving towards PostgreSQL after investigating some of the features that it provides. My question is, is there anything I need to worry about with this configuration? Limitations? Gotchas? Things to watch out for? There will be some BLOBs stored in the database (images, X.509 certificates, etc.) Will that be a problem using PostgreSQL? Are there any particular configuration changes or tweaks that I should make in my Hibernate configuration? Thanks for any advice you can give!

• How to detect Out Of Memory condition?

  - by Jaromir Hamala

  I have an application running on Websphere Application Server 6.0 and it crashes nearly every day because of Out-Of-Memory. From verbose GC is certain there are the memory leaks(many of them) Unfortunately the application is provided by external vendor and getting things fixed is slow & painful process. As part of the process I need to gather the logs and heapdumps each time the OOM occurs. Now I'm looking for some way how to automate it. Fundamental problem is how to detect OOM condition. One way would be to create shell script which will periodically search for new heapdumps. This approach seems me a kinda dirty. Another approach might be to leverage the JMX somehow. But I have little or no experience in this area and don't have much idea how to do it. Or is in WAS some kind of trigger/hooks for this? Thank you very much for every advice!

• Making a Mac double-clickable application in NetBeans

  - by skiaddict1

  I have recently moved to a MacBook Pro, which has meant leaving my beloved JBuilder 2005 behind. Since there is no such thing any more (AFAIK) as a free JBuilder, I'm having to choose a new IDE. I can't live with the code-formatting of Eclipse (yes, I know, it can be customised up the wazoo, but the fact that it will NOT respect my inserted returns means I can't live with it) so I'm seriously considering NetBeans. However, I can't find any way of getting it to build a double-clickable Mac application! (I used to use XCode for this step, but it seems that XCode no longer wants to know about Java...) I cannot be the first person who's wanted to do this...can anyone help me with advice as to how to go about it? Grateful thanks in advance

• Including the functionality of a tool within another program?

  - by darren

  Hi there I would like to write an application, for my own interest, that graphically visualizes some network concepts. Basically I would like to show the output from tools like ping, traceroute and nmap. The most obvious approach seems to be to use pipes to call out to these tools from my C program, and process the information they return. However, I would like to avoid this heavy-handed approach if possible. My question is, is it possible to somehow link against these tools, or are there APIs that can be used to gain programatic access instead? If so, is this behavior available on a tool-by-tool basis only? One reason for wanting to do this is to keep everything in a single process / address space and to avoid dependance on these external tools. For example, if I wrote an iphone application, I would not be able to spawn processes to call out to the external tools themselves. Thanks for any advice or suggestions.

• Ruby on Rails updating join table records

  - by Eef

  Hey, I have two models Users and Roles. I have setup a many to many relationship between the two models and I have a joint table called roles_users. I have a form on a page with a list of roles which the user checks a checkbox and it posts to the controller which then updates the roles_users table. At the moment in my update method I am doing this because I am not sure of a better way: role_ids = params[:role_ids] user.roles.clear role_ids.each do |role| user.roles << Role.find(role) end unless role_ids.nil? So I am clearing all the entries out then looping threw all the role ids sent from the form via post, I also noticed that if all the checkboxes are checked and the form posted it keeps adding duplicate records, could anyone give some advice on a more efficent way of doing this?

• How do I set up a test duplicate of a Django and Postgresql based web application?

  - by cojadate

  Not sure if this is an excessively broad and newbie-ish question for Stack Overflow but here goes: I paid someone else to build a web application for me and now I want to tweak certain aspects of it myself. I learn best by trial and error – changing stuff and seeing what happens. Obviously that's not a great way to treat a live site, so I need to duplicate the site on some kind of test server which I can play with without fear of the consequences. Unfortunately the closest I've come to programming has been creating ActionScript-based websites. I've never touched a database. So I really don't know where to start with setting up a test server. I would really appreciate any advice about where to start. I am completely ignorant and lost here. The web application is built in python/django using a Postgresql database. I use Mac OS X 10.6 if that makes any difference.

• Filter across 2 lists using LINQ

  - by Ajit Goel

  I have two lists: a. requestedAmenities b. units with amenities. I want to filter those units that have any one of the "requested amenities". I have tried to achieve the same result using foreach loops but I believe it should be much easier using LINQ. Can someone please help\advice? UnitAmenities unitSearchRequestAmenities = unitSearchRequest.Amenities; var exactMatchApartmentsFilteredByAmenities= new Units(); IEnumerable<string> requestAmenitiesIds = unitSearchRequestAmenities.Select(element => element.ID); foreach (var unitCounter in ExactMatchApartments) { IEnumerable<string> unitAmenities = unitCounter.Amenities.Select(element => element.ID); foreach (var requestAmenityId in requestAmenitiesIds) { foreach (var unitAmenity in unitAmenities) { if (requestAmenityId == unitAmenity) { exactMatchApartmentsFilteredByAmenities.Add(unitCounter); //break to the outmost foreach loop } } } }

• Can I send a ESC d command to a POS printer from perl?

  - by Bradleyb

  I have a Star TSP100 printer and I'm having few problems with it really. My problem is that I'm not as familiar with programming as I should be - but I'm learning! The programmers reference for the Star printer says that if I send a ESC d to the printer - that will activate the built-in cutter - which I would like to do very much. My problem is that I have no idea how to send an escape code like that from within PERL - if it's even possible. I really appreciate any advice on this one.

• Load external swf from a button in external swf and unload self?

  - by ChristinaR

  Hello, I am an uber n00b to flash AS3. And it is not my intention to sound like a complete moron, but honestly, I have had a hard enough time figuring out just how to load an external .swf into my main file! And now my friend is asking me if I could please add a button within the external .swf which will unload itself and load a new on in its place... I have looked around in the forums for an answer for a while now and I believe it is time for me to break down, admit defeat, and ask for help. Can someone please tell me it's not that difficult..? Surely it is possible... Thank you in advance for any advice at all! I am looking forward to the time when I can post a response here!

• Events in Classes (VB.NET)

  - by Otaku

  I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for. I could use some advice here. For example, in this one I always want to keep myColor up to date with any change whatsoever in any or all of the Red, Green or Blue properties. Class myColors Private Property Red As Byte Private Property Green As Byte Private Property Blue As Byte Private Property myColor As Color Sub New() myColor = Color.FromArgb(0, 0, 0) End Sub Sub ChangeRed(ByVal r As Byte) Red = r myColor = Color.FromArgb(Red, Green, Blue) End Sub Sub ChangeBlue(ByVal b As Byte) Blue = b myColor = Color.FromArgb(Red, Green, Blue) End Sub End Class If one or more of those changes, I want myColor to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue) in every sub routine?

• Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

  - by splicer

  I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

• Style Data in a gridview which dynamically generates the columns

  - by Coesy

  I have built a dynamic gridview using the following code grdVariants.Columns.Clear(); int i = 0; foreach (DataColumn column in options.Columns) { grdVariants.Columns.Add(new GridViewColumn { Header = column.ColumnName, DisplayMemberBinding = new Binding(string.Format("[{0}]", i++)) }); } This will dynamically generate my columns at runtime, I then bind the data using lstVariantsGrid.DataContext = options; lstVariantsGrid.Items.Refresh(); This all works great and shows the data in the correct columns etc, the only issue i have is that I can't style the rows like I would in xaml as it is all an unknown quantity until runtime. Can anyone offer some advice on how I might go about doing this? One of the biggest problems I have is that one of the columns needs to display the image rather than just the path which it currently shows, as well as fiddling with fonts and colors etc. Thanks for your time.

• Manually Adjusting UI for Rotation

  - by Driss Zouak

  In my view I have some number-pad type buttons that I want to manually adjust their X and Y when the view is rotated. I'm having trouble figuring out how to support this. I have added in my ViewDidLoad NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated ); And I defined my DeviceRotated but the breakpoint is never hit. I thought this might be because of the Autorotate, so I overrided the ShouldAutorotateToInterfaceOrientation and set that to false (true didn't work either). I figured there should be some WillRotate (but that's a void return type) or something that would allow me to indicate that I want the View to rotate, and whatever is set to auto adjust I'd like it to do that, but that I would like to be able to manually adjust any other items that I need. If I have to do everything myself, that's fine as well. Any advice would be appreciated, Driss.

• Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?

  - by Rahat

  Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

• Using a locale-dependent sorting function in Ruby/Rails

  - by knuton

  What is a good approach to sorting an array of strings in accordance with the current locale? For example the standard Array#sort puts "Ä" after "Z", which is not correct in German. I would have expected the gem I18n to offer a hook for defining my own sorting algorithms or providing collation strings or objects. In my imagination, passing this proc or string to the sort function, would make it behave as necessary. I know that this is possible in Python, for example. Google has not helped me this time. Can you? Any advice appreciated!

• How do I implement SAML 2.0 in a WCF Client?

  - by Tone

  I need to implement SAML 2.0 for a WCF client that is talking to a java web service (Glassfish). I know very little about SAML, and after a bit of searching here (and elsewhere) I do not find much about how to implement with WCF. Since WCF abstracts you away from the SOAP layer how can I add SAML assertions to the SOAP header? Will a 3rd party tool like ComponentSpace work best? Or should I roll my own? Other advice?

• Storing cvs data for further manipulation using Ruby

  - by ischnura

  I am dealing with a csv file that has some customer information (email, name, address, amount, [shopping_list: item 1, item 2]). I would like work with the data and produce some labels for printing... as well as to gather some extra information (total amounts, total items 1...) My main concern is to find the appropriate structure to store the data in ruby for future manipulation. For now I have thought about the following possibilities: multidimensional arrays: pretty simple to build, but pretty hard to access the data in a beautiful ruby way. hashes: having the email as key, and storing the information in different hashes (one hash for name, another hash for address, another hash for shopping list...) (getting the cvs data in to a Database and working with the data from ruby??) I would really appreciate your advice and guidance!!
