Conversion to Dalvik format failed error for Android Grid View

- by Bub

Hey Everyone, I'm on the android bandwagon and started going through google's "view" tutorials. Here is what I'm using: Eclipse Galileo Android SDK 2.1 Java SDK 6.Something I think. Everything was hunky-dory until I hit the grid view tutorial. I got errors all over the place when I started editing the "HelloGridview.java" File. I thought I'd fix it by following through with the next part of the tutorial, creating the ImageAdapter class, but it created more. I realized alot of my issues could be resolved by importing widgets which were not mentioned in the tutorial (i.e. android.widget.GridView, .ImageView, .BaseAdapter etc.) However, after all the reconciliation suggested by eclipse the files were finally showing no errors. I go to run it as an android app and bam, "Your project contains error(s)." window comes up. There are no errors showing on the files I've created. I cleared the error log and shut down eclipse and started again the error log now reads: Conversion to Dalvik format failed with error 1. I'm a little lost at this point. I think I've included the required information. If you need to know more let me know. Any help is appreciated.

Question about MySQLdb, OS X 10.5, and authentication

- by timpone

I'm a noob at Python and have been having problems with MySQLdb and OS X Leopard 10.5. I have a php app that is doing db access just fine with pdo but also want to access with Python. When I use the same credentials with MySQLdb as php, I get the following error: File "build/bdist.macosx-10.5-i386/egg/MySQLdb/connections.py", line 188, in __init__ _mysql_exceptions.OperationalError: (1045, "Access denied for user 'arc_db'@'localhost' (using password: YES)") The authentication piece works fine on my ubuntu server (installed via apt-get) implying that it is something specific to my OS X MySQLdb install. Looking at some postings, I thought it would be my local build of MySQLdb which seems to be problematic with OS X. But I am able to import fine: Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb >>> Also, wanting to create a positive, I am able to access and return results from a database tilted test_something (which presumably bypasses the MySQL's authtentication - not sure exactly how though). Trying to figure out a little more what is going on, I turn on logging for mysql and get the following (added my own comments): 100609 19:09:45 3 Connect Access denied for user 'arc_db'@'localhost' (using password: YES) //not worked 100609 19:10:02 4 Connect arc_db@localhost on arc_development //did work I'm not really sure what the 3 or 4 means but presumably a sucess or failue. So, I guess what would be the next step? Am I doing some obvious stupid python mistake (very likely)? Is there a better way for me to prove that this should / can be working? Is there any way to determine what MySQLdb is sending exactly in its authentication message to MySQL? thanks

Difficulty setting ArrayList to java.sql.Blob to save in DB using hibernate

- by me_here

I'm trying to save a java ArrayList in a database (H2) by setting it as a blob, for retrieval later. If this is a bad approach, please say - I haven't been able to find much information on this area. I have a column of type Blob in the database, and Hibernate maps to this with java.sql.Blob. The code I'm struggling with is: Drawings drawing = new Drawings(); try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = null; oos = new ObjectOutputStream(bos); oos.writeObject(plan.drawingPane21.pointList); byte[] buff = bos.toByteArray(); Blob drawingBlob = null; drawingBlob.setBytes(0, buff); drawing.setDrawingObject(drawingBlob); } catch (Exception e){ System.err.println(e); } The object I'm trying to save into a blob (plan.drawingPane21.pointList) is of type ArrayList<DrawingDot>, DrawingDot being a custom class implementing Serializable. My code is failing on the line drawingBlob.setBytes(0, buff); with a NullPointerException. Help appreciated.

Custom Database integration with MOSS 2007

- by Bob

Hopefully someone has been down this road before and can offer some sound advice as far as which direction I should take. I am currently involved in a project in which we will be utilizing a custom database to store data extracted from excel files based on pre-established templates (to maintain consistency). We currently have a process (written in C#.Net 2008) that can extract the necessary data from the spreadsheets and import it into our custom database. What I am primarily interested in is figuring out the best method for integrating that process with our portal. What I would like to do is let SharePoint keep track of the metadata about the spreadsheet itself and let the custom database keep track of the data contained within the spreadsheet. So, one thing I need is a way to link spreadsheets from SharePoint to the custom database and vice versa. As these spreadsheets will be updated periodically, I need tried and true way of ensuring that the data remains synchronized between SharePoint and the custom database. I am also interested in finding out how to use the data from the custom database to create reports within the SharePoint portal. Any and all information will be greatly appreciated.

Java List with Objects - find and replace (delete) entry if Object with certain attribute already ex

- by Sophomore

Hi there I've been working all day and I somehow can't get this probably easy task figured out - probably a lack of coffee... I have a synchronizedList where some Objects are being stored. Those objects have a field which is something like an ID. These objects carry information about a user and his current state (simplified). The point is, that I only want one object for each user. So when the state of this user changes, I'd like to remove the "old" entry and store a new one in the List. protected static class Objects{ ... long time; Object ID; ... } ... if (Objects.contains(ID)) { Objects.remove(ID); Objects.add(newObject); } else { Objects.add(newObject); } Obviously this is not the way to go but should illustrate what I'm looking for... Maybe the data structure is not the best for this purpose but any help is welcome!

Netbeans and EOF

- by sqlnoob

Hey there, Java, ANTLR and Netbeans newbie here. I have installed a jdk and netbeans. I started a new project on netbeans 6.8 and i have added the antlr-3.2.jar as a library. I also created a lexer and parser class using AntlrWorks. These classes are named ExprParser.java and ExprLexer.java. I copied them into a directory named path-to-netbeans-project/src/parsers. I have a main file: package javaapplication2; import org.antlr.runtime.*; import parsers.*; public class Main { public static void main(String[] args) throws Exception{ ANTLRInputStream input = new ANTLRInputStream(System.in); ExprLexer lexer = new ExprLexer(input); CommonTokenStream tokens = new CommonTokenStream(lexer); ExprParser parser = new ExprParser(tokens); parser.prog(); } } The application builds fine. The book I'm reading says I should run the program and type in some stuff and then press Ctrl+Z (I'm on windows) to send EOF to the console. Problem is that nothing happens when I press Ctrl+z in the netbeans console. When I run from the command line, ctrl+z works fine. This is probably WAY too much information, but I can't figure it out. Sorry. Probably not a good idea to learn 3 new technologies at once.

Entity Framework Multiple associations to a table causes error 3033

- by taylonr

I'm using EF 3.5 SP1. I have 3 tables: Pendants PendantAccessories PartsData Basically #1 and 2 are used for product selection, so #1 has a "Number of Buttons" property and other options. #2 has fields like "Cable Type" etc. The third table contains property information for all of our parts, such as what plant it's manufactured in, it's weight etc. What I'm trying to do is set up an association between #1 and #3 and also between #2 and #3. The PK in all 3 tables is the PartNumber. I set it up between #2 and 3 by going into Mapping Details and adding a Maps to PartsData and mapping the columns. Everything worked good. I then tried the same thing between #1 and 3. However, now when I compile I get "Error 3033: Problem in Mapping Fragment starting at line 713: EntitySets 'pendants' and 'pendantAccessories' are both mapped to the table 'PartsData'. Their Primary Keys may collide." Does anyone know what I'm doing wrong here?

Algorithm to match list of regular expressions

- by DSII

I have two algorithmic questions for a project I am working on. I have thought about these, and have some suspicions, but I would love to hear the community's input as well. Suppose I have a string, and a list of N regular expressions (actually they are wildcard patterns representing a subset of full regex functionality). I want to know whether the string matches at least one of the regular expressions in the list. Is there a data structure that can allow me to match the string against the list of regular expressions in sublinear (presumably logarithmic) time? This is an extension of the previous problem. Suppose I have the same situation: a string and a list of N regular expressions, only now each of the regular expressions is paired with an offset within the string at which the match must begin (or, if you prefer, each of the regular expressions must match a substring of the given string beginning at the given offset). To give an example, suppose I had the string: This is a test string and the regex patterns and offsets: (a) his.* at offset 0 (b) his.* at offset 1 The algorithm should return true. Although regex (a) does not match the string beginning at offset 0, regex (b) does match the substring beginning at offset 1 ("his is a test string"). Is there a data structure that can allow me to solve this problem in sublinear time? One possibly useful piece of information is that often, many of the offsets in the list of regular expressions are the same (i.e. often we are matching the substring at offset X many times). This may be useful to leverage the solution to problem #1 above. Thank you very much in advance for any suggestions you may have!

Ruby on Rails / Yellow Maps For Ruby Plugin woes...

- by Zach

Okay I've read through the plugin comments and the docs as well and I have yet to come up with an answer as to how to do this. Here's my problem I want to use the :info_window_tabs and the :icon option, but I don't know what format to pass my information in. According to the documentation the following code should be correct. Here's my code: @mapper.overlay_init(GMarker.new([map.lat, map.lng], :title => map.name, :info_window_tabs => [ {:tab => "HTML", :content => @marker_html}, {:tab => "Attachments", :content => "stuff"}], :icon => { :image => "../images/icon.png" })) The readme and documentation can be viewed here. And the relevant ruby file that I am trying to interact with, including the author's comments, can be viewed here. I have tried the #rubyonrails channel in IRC as well as emailing the author directly and reporting an issue at GitHub. It really is just a question of syntax. Thanks!

BackgroundWorker From ASP.Net Application

- by Kevin

We have an ASP.Net application that provides administrators to work with and perform operations on large sets of records. For example, we have a "Polish Data" task that an administrator can perform to clean up data for a record (e.g. reformat phone numbers, social security numbers, etc.) When performed on a small number of records, the task completes relatively quickly. However, when a user performs the task on a larger set of records, the task may take several minutes or longer to complete. So, we want to implement these kinds of tasks using some kind of asynchronous pattern. For example, we want to be able to launch the task, and then use AJAX polling to provide a progress bar and status information. I have been looking into using the BackgroundWorker class, but I have read some things online that make me pause. I would love to get some additional advice on this. For example, I understand that the BackgroundWorker will actually use the thread pool from the current application. In my case, the application is an ASP.Net web site. I have read that this can be a problem because when the application recycles, the background workers will be terminated. Some of the jobs I mentioned above may take 3 minutes, but others may take a few hours. Also, we may have several hundred administrators all performing similar operations during the day. Will the ASP.Net application thread pool be able to handle all of these background jobs efficiently while still performing it's normal request processing? So, I am trying to determine if using the BackgroundWorker class and approach is right for our needs. Should I be looking at an alternative approach? Thanks and sorry for such a long post! Kevin

Figuring out the performance limitation of an ADC on a PIC microcontroller

- by AKE

I'm spec-ing the suitability of a microcontroller like PIC for an analog-to-digital application. This would be preferable to using external A/D chips. To do that, I've had to run through some computations, pulling the relevant parameters from the datasheets. I'm not sure I've got it right -- would appreciate a check! Here's the simplest example: PIC10F220 is the simplest possible PIC with an ADC. Runs at clock speed of 8MHz. Has an instruction cycle of 0.5us (4 clock steps per instruction) So: Taking Tacq = 6.06 us (acquisition time for ADC, assume chip temp. = 50*C) [datasheet p34] Taking Fosc = 8MHz (? clock speed) Taking divisor = 4 (4 clock steps per CPU instruction) This gives TAD = 0.5us (TAD = 1/(Fosc/divisor) ) Conversion time is 13*TAD [datasheet p31] This gives conversion time 6.5us ADC duration is then 12.56 us [? Tacq + 13*TAD] Assuming at least 2 instructions for load/store: This is another 1 us [0.5 us per instruction] Which would give max sampling rate of 73.7 ksps (1/13.56) Supposing 8 more instructions for real-time processing: This is another 4 us Thus, total ADC/handling time = 17.56us (12.56us + 1us + 4us) So expected upper sampling rate is 56.9 ksps. Nyquist frequency for this sampling rate is therefore 28 kHz. If this is right, it suggests the (theoretical) performance suitability of this chip's A/D is for signals that are bandlimited to 28 kHz. Is this a correct interpretation of the information given in the data sheet? Any pointers would be much appreciated! AKE

Looking for a smarter way to convert a Python list to a GList?

- by Kingdom of Fish

I'm really new to C - Python interaction and am currently writing a small app in C which will read a file (using Python to parse it) and then using the parsed information to execute small Python snippets. At the moment I'm feeling very much like I'm reinventing wheels, for example this function: typedef gpointer (list_func)(PyObject *obj); GList *pylist_to_glist(list_func func, PyObject *pylist) { GList *result = NULL; if (func == NULL) { fprintf(stderr, "No function definied for coverting PyObject.\n"); } else if (PyList_Check(pylist)) { PyObject *pIter = PyObject_GetIter(pylist); PyObject *pItem; while ((pItem = PyIter_Next(pIter))) { gpointer obj = func(pItem); if (obj != NULL) result = g_list_append(result, obj); else fprintf(stderr, "Could not convert PyObject to C object.\n"); Py_DECREF(pItem); } Py_DECREF(pIter); } return result; } I would really like to do this in a easier/smarter way less prone to memory leaks and errors. All comments and suggestions are appreciated.

Catching MediaPlayer Exceptions from WPF MediaElement Control

- by ScottCate

I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

Entity Framework Update Error in ASP.NET Mvc with related entity

- by Barry

I have run into a problem which have searched and tried everything i can to find a solution but to no avail. I am using the same repository and context throughout the process I have a booking entity and a userExtension Entity Below is my image i then get my form collection back from my page and create a new booking public ActionResult Create(FormCollection collection) { Booking toBooking = new Booking(); i then do some validation and property assignment and find an associated BidInstance toBooking.BidInstance = bid; i have checked and the bid is not null. finally i get the user extension file from the Current IPRINCIPAL USER as below UserExtension loggedInUser = m_BookingRepository.GetBookingCurrentUser(User); toBooking.UserExtension = loggedInUser; The Code to do the getUserExtension is : public UserExtension GetBookingCurrentUser(IPrincipal currentUser) { var user = (from u in Context.aspnet_Users .Include("UserExtension") where u.UserName == currentUser.Identity.Name select u).FirstOrDefault(); if (user != null) { var userextension = (from u in Context.UserExtension.Include("aspnet_Users") where u.aspnet_Users.UserId == user.UserId select u).FirstOrDefault(); return userextension; } else{ return null; } } It returns the userextension fine and assigns it fine. i originally used the aspnet_users but encountered this problem so tried to change it to the extension entity. as soon as i call the : Context.AddToBooking(booking); Context.SaveChanges(); i get the following exception and im completely baffled by how to fix it Entities in 'FutureFlyersEntityModel.Booking' participate in the 'FK_Booking_UserExtension' relationship. 0 related 'UserExtension' were found. 1 'UserExtension' is expected. then the final error that comes to the front end is: Metadata information for the relationship 'FutureFlyersModel.FK_Booking_BidInstance' could not be retrieved. Make sure that the EdmRelationshipAttribute for the relationship has been defined in the assembly. Parameter name: relationshipName.. But both the related entities are set in the booking entity passed thruogh PLEASE HELP Im at wits end with this

Jquery getJSON() doesn't work when trying to get data from java server on localhost

- by bellesebastien

The whole day yesterday I've been trying to solve this but it's proven to be very challenging for me. I'm trying to use this JS to get information from a java application I wrote. $(document).ready(function() { $.getJSON('http://localhost/custest?callback=?', function(json) { alert('OK'); $('.result').html(json.description); }); }); The Java application uses httpServer and is very basic. When I access the page 'http://localhost/custest?callback=?' with Firefox, the browser shows me the server is sending me json data and asks with what to open it with, but when I try it from a webpage using the JS above it doesn't work. The getJSON call is not successful, the alert("ok") doesn't popup at all. If it replace "http://localhost/custest?callback=?" in the JS with "http://twitter.com/users/usejquery.json?callback=?" everything works fine. An interesting thing is that if I send malformed JSON from my java server Firebug gives an error and tells me what is missing from the JSON so that mean the browser is receiving the JSON data, but when I send it correct a JSON string nothing happens, no errors, not even the alert() opens. I'm adding the headers in case you think these could be relevant. http://localhost/custest?callback=jsonp1274691110349 GET /custest?callback=jsonp1274691110349 HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive HTTP/1.1 200 OK Transfer-Encoding: chunked Content-Type: application/json Thanks for your help

Can a single developer still make money with shareware?

- by Wouter van Nifterick

I'm wondering if the shareware concept is dead nowadays. Like most developers, I've built up quite a collection of self-made tools and code libraries that help me to be productive. Some examples to give you an idea of the type of thing I'm talking about: A self-learning program that renames and orders all my mp3 files and adds information to the id3 tags; A Delphi component that wraps the Google Maps API; A text-to-singing-voice converter for musical purposes; A program to control a music synthesizer; A Gps-log <- KML <- ESRI-shapefile converter; I've got one of these already freely downloadable on my website, and on average it gets downloaded about a 150 times per month. Let's say I'd start charging 15 euro's for it; would there actually be people who buy it? How many? What would it depend on? If I could get some money for some of these, I'd finish them up a bit and put them online, but without that, I probably won't bother. Maintaining a SourceForge project is not very rewarding by itself. Is there anyone who is making money with shareware? How much? Any tips?

Writing to a log4net FileAppender with multiple threads performance problems

- by Wayne

TickZoom is a very high performance app which uses it's own parallelization library and multiple O/S threads for smooth utilization of multi-core computers. The app hits a bottleneck where users need to write information to a LogAppender from separate O/S threads. The FileAppender uses the MinimalLock feature so that each thread can lock and write to the file and then release it for the next thread to write. If MinimalLock gets disabled, log4net reports errors about the file being already locked by another process (thread). A better way for log4net to do this would be to have a single thread that takes care of writing to the FileAppender and any other threads simply add their messages to a queue. In that way, MinimalLock could be disabled to greatly improve performance of logging. Additionally, the application does a lot of CPU intensive work so it will also improve performance to use a separate thread for writing to the file so the CPU never waits on the I/O to complete. So the question is, does log4net already offer this feature? If so, how do you do enable threaded writing to a file? Is there another, more advanced appender, perhaps? If not, then since log4net is already wrapped in the platform, that makes it possible to implement a separate thread and queue for this purpose in the TickZoom code. Sincerely, Wayne

How do I best display CheckBoxes in SQL Server Reporting Services?

- by Yadyn

One of the many quirks of Reporting Services we've run across is the complete and utter lack of a CheckBox control or even something remotely similar. We have a form that should appear automatically filled out based on information pulled from a database. We have several bit datatype fields. Printing out "True" or "False" just looks silly, as this is supposed to look like a form that has been auto-filled out, so we want to have a series of checkboxes and labels that are either checked or unchecked. We are running SSRS 2005 but I'm not aware of SSRS 2008 having added a CheckBox control. Even if it did, we'd need to have an alternative for the time being. The best we've found so far is: use Wingdings use images use text boxes with borders and print a blank/space or a capital X All three approaches require IIF expression shenanigans. The Wingdings approach seemed to work acceptably, and was the most aesthetically pleasing except that for whatever reason it didn't always print correctly. More importantly, PDF exports, also for whatever reason, converted all fonts (generally) to Arial and so we got funky letters instead of the Windings dingbats. Images, being a pixel-based raster, don't do so well when printed along side vector stuff like text. Unless handled carefully, they tend to stretch, pixelate, and do other unprofessional looking things. While these methods do work (some with limitations as mentioned above) none of them are particularly elegant. Are we missing something obvious? Not so obvious? Does someone at Microsoft have a good reason why such a control was not provided in SSRS 2000, let alone 2 versions and 8 years later? This can't be the first time this issue has come up...

Can't change pivot table's Access data source - bug in Excel 2000 SP3?

- by Ron West

I have a set of Excel 2000 SP3 worksheets that have Pivot Tables that get data from an Access 2000 SP3 database created by a contractor who left our company. Unfortunately, he did all his work on his private area on the company (Novell) network and now that he has left us, the drive spec has been deleted and is invalid. We were able to get the database files restored to our network area by our IT Service Desk people, but we now have to re-link everything to point to our group area instead of the now-nonexistent private area. If I follow the advice given elsewhere on this site (open wizard, click 'Back' to get to 'Step 2 of 3', click 'Get Data...' I get a message that the old filespec is an invalid path and I need to check that the path name is invalid and that I am connected to the server on which the file resides. I then click on OK and get a Login dialog with a 'Database...' button on the right. I click this and get a 'Select Database' dialog which allows me to choose the appropriate database in its correct new location. I then click OK, which takes me back to the 'Login' screen. I can confirm that it has accepted my new location by clicking on 'Database...' as before and the NEW location is still shown. So far so good - but if I then click on OK I get two unhelpful messages - first I get one saying that Excel 'Could not use '|'; file already in use.' - although no other files are in use. Clicking on OK takes me back to the 'Login' dialog. Clicking OK again gives me the same message as before telling me that the OLD filespec is invalid (as if I hadn't changed anything) - but clicking on the 'Database...' button shows that the correct (NEW) database location is still selected. Can anyone tell me a way of using VBA to change the link information without having to spend hours fighting the PivotTable Wizard - preferably similar to this way you update an Access Tabledef:- db.TableDefs(strLinkName).Connect = strNewLink db.TableDefs(strLinkName).RefreshLink Thanks!

C# - Alternative to System.Time.Timer, to call a function at a specific time.

- by Fábio Antunes

Hello everybody. I want to call a specific function on my C# application at a specific time. At first i thought about using a Timer (System.Time.Timer), but that soon became impossible to use. Why? Simple. The Timer Class requires a Interval in milliseconds, but considering that i might want the function to be executed, lets says in a week that would mean: 7 Days = 168 hours; 168 Hours = 10,080 minutes; 10,080 Minutes = 6,048,000 seconds; 6,048,000 Seconds = 6,048,000,000 milliseconds; So the Interval would be 6,048,000,000; Now lets remember that the Interval accepted data type is int, and as we know int range goes from -2,147,483,648 to 2,147,483,647. That makes Timer useless in this case once we cannot set a Interval bigger that 2,147,483,647 milliseconds. So i need a solution where i could specify when the function should be called. Something like this: solution.ExecuteAt = "30-04-2010 15:10:00"; solution.Function = "functionName"; solution.Start(); So when the System Time would reach "30-04-2010 15:10:00" the function would be executed in the application. How can this problem be solved? Thanks just by taking the time to read my question. But if you could provide me with some help i would be most grateful. Additional Info: What these functions will do? Getting climate information and based on that info: Starting / Shutting down other Applications (most of them Console Based); Sending custom Commands to those Console Applications; Power down, Rebooting, Sleep, Hibernate the computer; And if possible schedule the BIOS to Power Up the Computer;

Subselecting with MDX

- by Vince

Greetings stack overflow community. I've recently started building an OLAP cube in SSAS2008 and have gotten stuck. I would be grateful if someone could at least point me towards the right direction. Situation: Two fact tables, same cube. FactCalls holds information about calls made by subscribers, FactTopups holds topup data. Both tables have numerous common dimensions one of them being the Subscriber dimension. FactCalls FactTopups SubscriberKey SubscriberKey CallDuration DateKey CallCost Topup Value ... What I am trying to achieve is to be able to build FactCalls reports based on distinct subscribers that have topped up their accounts within the last 7 days. What I am basically looking for an MDX equivalent to SQL's: select * from FactCalls where SubscriberKey in ( select distinct SubscriberKey from FactTopups where ... ); I've tried creating a degenerate dimension for both tables containing SubscriberKey and doing: Exist( [Calls Degenerate].[Subscriber Key].Children, [Topups Degenerate].[Subscriber Key].Children ) Without success. Kind regards, Vince

Issue with IHttpHandler and relative URLs

- by vtortola

Hi, I've developed a IHttpHandler class and I've configured it as verb="*" path="*", so I'm handling all the request with it in an attempt of create my own REST implementation for a test web site that generates the html dynamically. So, when a request for a .css file arrives, I've to do something like context.Response.WriteFile(Server.MapPath(url)) ... same for pictures and so on, I have to response everything myself. My main issue, is when I put relative URLs in the anchors; for example, I have main page with a link like this <a href="page1">Go to Page 1</a> , and in Page 1 I have another link <a href="page2">Go to Page 2</a>. Page 1 and 2 are supposed to be at the same level (http://host/page1 and http://host/page2, but when I click in Go to Page 2, I got this url in the handler: ~/page1/~/page2 ... what is a pain, because I have to do an url = url.SubString(url.LastIndexOf('~')) for clean it, although I feel that there is nothing wrong and this behavior is totally normal. Right now, I can cope with it, but I think that in the future this is gonna bring me some headache. I've tried to set all the links with absolute URLs using the information of context.Request.Url, but it's also a pain :D, so I'd like to know if there is a nicer way to do these kind of things. Don't hesitate in giving me pretty obvious responses because I'm pretty new in web development and probably I'm skipping something basic about URLs, Http and so on. Thanks in advance and kind regards.
