  • Having issue Deserializing array from an XML string

    - by LeeHull
    I'm having issues trying to deserializing my xml string that was from a dataset.. Here is the XML layout.. <DataSet> <User> <UserName>Test</UserName> <Email>[email protected]</Email> <Details> <ID>1</ID> <Name>TestDetails</Name> <Value>1</Value> </Details <Details> <ID>2</ID> <Name>Testing</Name> <Value>3</Value> </Details </User> </DataSet> Now I am able to deserialize the "UserName" and "Email" when doing public class User { public string UserName {get;set;} public string Email {get;set;} public Details[] Details {get;set;} } public class Details { public int ID {get;set;} public string Name {get;set;} public string Value {get;set;} } This deserializes fine when I just get the user node, the Details isnt null but has no items in it.. i know I am suppose to have between all the details but I rather not modify the XML, anyways to get this to deserialize properly without recreating the XML after I get it?

  • Jquery UI Dialog - when opened IE7 Browser moves instantly to the bottom of the page

    - by Truegilly
    Hello, i have been working on a new .net MVC site and have integrated some of the awesome jquery UI components. ive been testing it in IE8, FF, opera and Chrome and all looks well. Once I test in IE7, surprisingly its the dialogs that are causing a problem. basically what’s happening is that one you user clicks to open a dialog the page will scroll immediately to the bottom of the page. This is especially bad if the page is quite long. this only happens in IE7 (and probably 6 but im not even going there!). I have spend a few hours reading forums and it seems im not the only one. I have created a dirty hack which im not keen on but it does work. onclick="SignIn(); <% if(ModelHelperClass.CheckForOldIEVersion() == true) Response.Write("window.scrollTo(0, 0);"); %> return false;"> has anyone else had this issue and resolved it without resorting to dirty hacks ? im using jquery-ui-1.8.custom.min.js and jquery-1.4.2.min.js any help is most appreciated Truegilly

  • Access violations in strange places when using Windows file dialogs

    - by Robert Oschler
    A long time ago I found out that I was getting access violations in my code due to the use of the Delphi Open File and/or Save File dialogs, which encapsulate the Windows dialogs. I asked some questions on a few forums and I was told that it may have been due to the way some programs add hooks to the shell system that result in DLLs getting injected in every process, some of which can cause havoc with a program. For the record, the programming environment I use is Delphi 6 Professional running on Windows XP 32-bit. At the time I got around it by not using Delphi's Dialog components and instead calling straight into comdlg32.dll. This solved the problem wonderfully. Today I was working with memory mapped files for the first time and sure enough, access violations started cropping up in weird parts of the code. I tried my comdlg32.dll direct calls and this time it didn't help. To isolate the problem as a test I created a list box with the exact same files I was using during testing. These are the exact same test files I was selecting from an Open File dialog and then launching my memory mapped file with. I set things up so that by clicking on a file in the list box, I would use that file in my memory mapped file test instead of calling into a comdlg32.dll dialog function to select a test file. Again, the access violatons vanished. To show you how dramatic a fix it was I went from experiencing an access violation within 1 to 3 trials to none at all. Unfortunately, it's going to bite me later on of course when I do need to use file dialogs. Has anyone else dealt with this issue too and found the real culprit? Did any of you find a solution I could use to fix this problem instead of dancing around it like I am now? Thanks in advance.

  • PayPal IPN "FAIL"

    - by Rob
    Hey all... I'm trying to figure out how to use PayPal's IPN and I've run into a wall. I want a buyer to be forwarded to a success page after making a purchase, and I want that page to show the details of their transaction. I choose IPN instead of the PDT because I also want to do some other behind the scenes stuff with their data. Anyway, here's the code I'm using -- I'm testing in sandbox mode -- but it returns "FAIL" every time. $req = 'cmd=_notify-validate'; foreach ($_POST as $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } // post back to PayPal system to validate $header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) . "\r\n\r\n"; $fp = fsockopen ('www.sandbox.paypal.com', 80, $errno, $errstr, 30); if (!$fp) { // HTTP ERROR } else { fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); if (strcmp ($res, "VERIFIED") == 0) { // PAYMENT VALIDATED & VERIFIED! echo "Validated!"; } else if (strcmp ($res, "INVALID") == 0) { // PAYMENT INVALID & INVESTIGATE MANUALY! echo "Invalid!"; } } fclose ($fp); }

  • Get instance of type inheriting from base class, implementing interface, using StructureMap

    - by Ben
    Continuing on my quest for a good plugin implementation I have been testing the StructureMap assembly scanning features. All plugins will inherit from abstract class PluginBase. This will provide access to common application services such as logging. Depending on it's function, each plugin may then implement additional interfaces, for example, IStartUpTask. I am initializing my plugins like so: Scan(x => { x.AssembliesFromPath(HttpContext.Current.Server.MapPath("~/Plugins"), assembly => assembly.GetName().Name.Contains("Extension")); x.AddAllTypesOf<PluginBase>(); }); The difficulty I am then having is how to work against the interface (not the PluginBase) in code. It's easy enough to work with PluginBase: var plugins = ObjectFactory.GetAllInstances<PluginBase>(); foreach (var plugin in plugins) { } But specific functionality (e.g. IStartUpTask.RunTask) is tied to the interface, not the base class. I appreciate this may not be specific to structuremap (perhaps more a question of reflection). Thanks, Ben

  • Dumping an ADODB recordset to XML, then back to a recordset, then saving to the db

    - by Mark Biek
    I've created an XML file using the .Save() method of an ADODB recordset in the following manner. dim res dim objXML: Set objXML = Server.CreateObject("MSXML2.DOMDocument") 'This returns an ADODB recordset set res = ExecuteReader("SELECT * from some_table) With res Call .Save(objXML, 1) Call .Close() End With Set res = nothing Let's assume that the XML generated above then gets saved to a file. I'm able to read the XML back into a recordset like this: dim res : set res = Server.CreateObject("ADODB.recordset") res.open server.mappath("/admin/tbl_some_table.xml") And I can loop over the records without any problem. However what I really want to do is save all of the data in res to a table in a completely different database. We can assume that some_table already exists in this other database and has the exact same structure as the table I originally queried to make the XML. I started by creating a new recordset and using AddNew to add all of the rows from res to the new recordset dim outRes : set outRes = Server.CreateObject("ADODB.recordset") dim outConn : set outConn = Server.CreateObject("ADODB.Connection") dim testConnStr : testConnStr = "DRIVER={SQL Server};SERVER=dev-windows\sql2000;UID=myuser;PWD=mypass;DATABASE=Testing" outConn.open testConnStr outRes.activeconnection = outConn outRes.cursortype = adOpenDynamic outRes.locktype = adLockOptimistic outRes.source = "product_accessories" outRes.open while not res.eof outRes.addnew for i=0 to res.fields.count-1 outRes(res.fields(i).name) = res(res.fields(i).name) next outRes.movefirst res.movenext wend outRes.updatebatch But this bombs the first time I try to assign the value from res to outRes. Microsoft OLE DB Provider for ODBC Drivers error '80040e21' Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. Can someone tell me what I'm doing wrong or suggest a better way for me to copy the data loaded from XML to a different database?

  • Yet another "What is this code doing"-type of Perl code

    - by Mike
    I have inherited some code from a guy whose favorite past time was to shorten every line to its absolute minimum (and sometimes only to make it look cool). His code is hard to understand but I managed to understand (and rewrite) most of it. Now I have stumbled on a piece of code which, no matter how hard I try, I cannot understand. my @heads = grep {s/\.txt$//} OSA::Fast::IO::Ls->ls($SysKey,'fo','osr/tiparlo',qr{^\d+\.txt$}) || (); my @selected_heads = (); for my $i (0..1) { $selected_heads[$i] = int rand scalar @heads; for my $j (0..@heads-1) { last if (!grep $j eq $_, @selected_heads[0..$i-1]); $selected_heads[$i] = ($selected_heads[$i] + 1) % @heads; #WTF? } my $head_nr = sprintf "%04d", $i; OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].txt","$recdir/heads/$head_nr.txt"); OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].cache","$recdir/heads/$head_nr.cache"); } From what I can understand, this is supposed to be some kind of randomizer, but I never saw a more complex way to achieve randomness. Or are my assumptions wrong? At least, that's what this code is supposed to do. Select 2 random files and copy them. === NOTES === The OSA Framework is a Framework of our own. They are named after their UNIX counterparts and do some basic testing so that the application does not need to bother with that.

  • What MS technology to use for HTTP service returning XML?

    - by Borek
    I need to create a service that: accepts HTTP requests (with query string or HTTP POST parameters) does some processing on the requests (checking if the request is valid, authentication etc.) reads data from a custom store (another HTTP call in our case) returns the result as custom XML (defined with XSD) I'm trying to think of various MS technologies that could help me and how good they would be for this scenario (pretty standard one I guess). The tasks above are relatively separate, this is what comes to mind: HTTP front-end: ASP.NET Web Forms ASP.NET MVC (seems more appropriate here as I won't need server controls, view state etc.) WCF? Don't know much about it or how well it would suit my task. Custom logic on the server: this will probably be a generic C# code in all cases (sometimes "plugged into" or called from MVC controllers or some equivalent place in other technologies) Reading data from internal data stores: As said, this is another HTTP server in our case. Options that come to mind: Just read the data using something like WebClient (Just theoretically) implement a LINQ provider (Just even more theoretically) implement an EF provider Output the data as custom XML: Linq2XML Serialization? Is it flexible enough? Does WCF provide some tools for this? Some "OXM" - Object/XML mapper if there is something like that for .NET I may be wrong in many of my assumptions, this is just a quick list that comes to mind after a quick research. Some general notes / questions: Testing is important Solution with a clear domain model would be much preferred over the one without Can Entity Framework actually help somewhere in my scenario? If so, where and how? Would WCF be an appropriate technology for this? I don't know much about it.

  • Blackberry application works in simulator but not device

    - by Kai
    I read some of the similar posts on this site that deal with what seems to be the same issue and the responses didn't really seem to clarify things for me. My application works fine in the simulator. I believe I'm on Bold 9000 with OS 4.6. The app is signed. My app makes an HTTP call via 3G to fetch an XML result. type is application/xhtml+xml. In the device, it gives no error. it makes no visual sign of error. I tell the try catch to print the results to the screen and I get nothing. HttpConnection was taken right out of the demos and works fine in sim. Since it gives no error, I begin to reflect back on things I recall reading back when the project began. deviceside=true? Something like that? My request is simply HttpConnection connection = (HttpConnection)Connector.open(url); where url is just a standard url, no get vars. Based on the amount of time I see the connection arrows in the corner of the screen, I assume the app is launching the initial communication to my server, then either getting a bad result, or it gets results and the persistent store is not functioning as expected. I have no idea where to begin with this. Posting code would be ridiculous since it would be basically my whole app. I guess my question is if anyone knows of any major differences with device versus simulator that could cause something like http connection or persistent store to fail? A build setting? An OS restriction? Any standard procedure I may have just not known about that everyone should do before beginning device testing? Thanks

  • undefined returned for currentView object in Backbone.Marionette

    - by ontk
    I am testing how a layout can listen to its subviews's custom events. I created a jsFiddle here where I have a layout, 2 regions and I instantiated 2 ItemViews and showed them in the layout's regions. The fiddle is in CoffeeScript. <div id="region"></div> <script id="layout-tmpl" type="text/_"> <h3>Heading</h3> <div id="content"></div> <div id="content2"></div> </script> <script id="item-tmpl" type="text/_"> <form> <label>Firstname:</lable> <input type="text" name="firstname" value="<%= firstname %>" /> <input type="button" value="Save" id="save" /> </form> </script> And the CoffeeScript is: SimpleLayout = Backbone.Marionette.Layout.extend template: '#layout-tmpl' regions: main: '#content' other: '#content2' initialize: () -> console.log @ onShow: () -> _.each @.regionManagers, (region, name, something) => console.log region.currentView # @.bindTo region.currentView, "custom:event", @callback callback: () -> alert "HELL YEAH" SimpleItemView = Backbone.Marionette.ItemView.extend template: "#item-tmpl" events: 'click #save': 'save' save: (evt) -> evt.preventDefault() @.trigger "custom:event" region = new Backbone.Marionette.Region el: "#region" layout = new SimpleLayout() region.show layout layout.main.show new SimpleItemView model: (new Backbone.Model firstname: "Olivier") layout.other.show new SimpleItemView model: (new Backbone.Model firstname: "Travis") I want the layout to listen to the ItemViews's custom events. In the onShow, I am looping through the region managers and trying to access the currentView object but it returns undefined. If I attach the same event handlers outside of the SimpleLayout class and after I show the itemviews, then the layout handlers the custom events properly. Thanks for your help.

  • How can I create a properly sizing QWebView?

    - by chacham15
    I want to make a QWebView appear expanding to the width and height so that ideally it will have no scroll bars. Some websites may have fixed widths that wont allow this, but I am not concerned with those. In any case, I cannot do as I wish because QWebView implements sizeHint as follows: QSize QWebView::sizeHint() const { return QSize(800, 600); // ####... } This is incorrect on a number of levels. 1. It doesnt at all take into account the size of the actual web page. 2. It doesnt take into account that the height and width are related to each other. (To prove #2 think about text in web pages that wraps to the next line.) As a simple fix I tried to do (where QResizingWebView extends QWebView): QSize QResizingWebView::sizeHint() const{ return this-page()-mainFrame()-contentsSize(); } While this is closer to the result, it also has 2 flaws. 1. It doesnt take into account the relation between the displayed width/height. 2. this->page()->mainFrame()->contentsSize() is inaccurate from what I can tell from my preliminary testing (it has returned heights larger than it should under many cases, although this may be related to #1). Does anyone have any tips to fix this?

  • document.write Not working when loading external Javascript source

    - by jadent
    I'm trying to load an external JavaScript file dynamically into an HTML element to preview an ad tag. The script loads and executes but the script contains "document.write" which has an issue executing properly but there are no errors. <html> <head> <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> <script type="text/javascript"> $(function() { source = 'http://ib.adnxs.com/ttj?id=555281'; // DOM Insert Approach // ----------------------------------- var script = document.createElement('script'); script.setAttribute('type', 'text/javascript'); script.setAttribute('src', source); document.body.appendChild(script); }); </script> </head> <body> </body> </html> I can get it to work if If i move the the source to the same domain for testing If the script was modified to use document.createElement and appendChild instead of document.write like the code above. I don't have the ability to modify the script since it being generated and hosted by a 3rd party. Does anyone know why the document.write will not work correctly? And is there a way to get around this? Thanks for the help!

  • Working with Decimal fields in SSIS

    - by CoffeeAddict
    I'm using SQL Server 2008 w/SP2. I've got an incoming decimal(9,2) field incoming through my OLE DB transformation to my recordset destination transformation. It's like it's reading it as something other than a decimal? I don't know..I'm not an SSIS guru. So continuing on...the problem I have starts here with me trying to stuff the value into a variable for this decimal field. In a foreach loop, I have a variable to represent this decimal field so I can work with it. The first problem that I believe is pretty well known is SSIS variables do not have a decimal type. And from my own testing and what I've read out there, people are using type object for the variable to make SSIS "happy" with decimal values? It makes mine happy. But, then in my foreach loop, I have a for loop. And inside that I'm using an E*xecute SQL Task transformation*. In it, I need to create a parameter mapping to my variable so I can work with that decimal field in my T-SQL call in here. So now I see a type decimal for the parameter and use it and set that to point to my variable. When I run SSIS and it hits my SQL call, I get this in my output window.: The type is not supported.DBTYPE_DECIMAL So I am hitting a wall here. All I wanna do is work with a decimal!!!

  • How do I launch background jobs w/ paramiko?

    - by sophacles
    Here is my scenario: I am trying to automate some tasks using Paramiko. The tasks need to be started in this order (using the notation (host, task)): (A, 1), (B, 2), (C, 2), (A,3), (B,3) -- essentially starting servers and clients for some testing in the correct order. Further, because in the tests networking may get mucked up, and because I need some of the output from the tests, I would like to just redirect output to a file. In similar scenarios the common response is to use 'screen -m -d' or to use 'nohup'. However with paramiko's exec_cmd, nohup doesn't actually exit. Using: bash -c -l nohup test_cmd & doesnt work either, exec_cmd still blocks to process end. In the screen case, output redirection doesn't work very well, (actually, doesnt work at all the best I can figure out). So, after all that explanation, my question is: is there an easy elegant way to detach processes and capture output in such a way as to end paramiko's exec_cmd blocking? Update The dtach command works nicely for this!

  • Hibernate: deletes not cascading for self-referencing entities

    - by jwaddell
    I have the following (simplified) Hibernate entities: @Entity @Table(name = "package") public abstract class Package { protected Content content; @ManyToOne(cascade = {javax.persistence.CascadeType.ALL}) @JoinColumn(name = "content_id") @Fetch(value = FetchMode.JOIN) public Content getContent() { return content; } public void setContent(Content content) { this.content = content; } } @Entity @Table(name = "content") public class Content { private Set<Content> subContents = new HashSet<Content>(); @ManyToMany(fetch = FetchType.EAGER) @JoinTable(name = "subcontents", joinColumns = {@JoinColumn(name = "content_id")}, inverseJoinColumns = {@JoinColumn(name = "elt")}) @Cascade(value = {org.hibernate.annotations.CascadeType.DELETE, org.hibernate.annotations.CascadeType.REPLICATE}) @Fetch(value = FetchMode.SUBSELECT) public Set<Content> getSubContents() { return subContents; } public void setSubContents(Set<Content> subContents) { this.subContents = subContents; } } So a Package has a Content, and a Content is self-referencing in that it has many sub-Contents (which may contain sub-Contents of their own etc). The relationships are required to be ManyToOne (Package to Content) and ManyToMany (Content to sub-Contents) but for the case I am currently testing each sub-Content only relates to one Package or Content. The problem is that when I delete a Package and flush the session, I get a Hibernate error stating that I'm violating a foreign key constraint on table subcontents, with a particular content_id still referenced from table subcontents. I've tried specifically (recursively) deleting the Contents before deleting the Package but I get the same error. Is there a reason why this entity tree is not being deleted properly?

  • Perl program for extracting the functions alone in a Ruby file

    - by thillaiselvan
    Hai all, I am having the following Ruby program. puts "hai" def mult(a,b) a * b end puts "hello" def getCostAndMpg cost = 30000 # some fancy db calls go here mpg = 30 return cost,mpg end AltimaCost, AltimaMpg = getCostAndMpg puts "AltimaCost = #{AltimaCost}, AltimaMpg = {AltimaMpg}" I have written a perl script which will extract the functions alone in a Ruby file as follows while (<DATA>){ print if ( /def/ .. /end/ ); } Here the <DATA> is reading from the ruby file. So perl prograam produces the following output. def mult(a,b) a * b end def getCostAndMpg cost = 30000 # some fancy db calls go here mpg = 30 return cost,mpg end But, if the function is having block of statements, say for example it is having an if condition testing block means then it is not working. It is taking only up to the "end" of "if" block. And it is not taking up to the "end" of the function. So kindly provide solutions for me. Example: def function if x > 2 puts "x is greater than 2" elsif x <= 2 and x!=0 puts "x is 1" else puts "I can't guess the number" end #----- My code parsing only up to this end Thanks in Advance!

  • Aspect-Oriented Programming in OOP world - breaking rules ?

    - by Maksim Kondratyuk
    Hi 2 all! When I worked on asp.net mvc web site project, I investigated different approaches for validation. Some of them were DataAnotation validation and Validation Block. They use attributes for setting up rules for validation. Like this: [Required] public string Name {get;set;} I was confused how this approach combines with SRP (single responsibilty principle) from OOP world. Also I don't like any business logic in business objects, I prefer "poor business objects" model, but when I decorate my business objects with validation attributes for real requirements, they become ugly (Has a lot of attributes / with localization logic and so on). Idea with attributes realy simple, but in my opinion the validation decoration should be separated from object. I'm not sure is the approach to separate validation rules to xml files or to another objects, maybe it is a solution. Another bad side of AOP - problems with unit testin such code. When I decorated some controller actions with custom attributes for example to import/export TempData between actions or initialize some required services I can't to write proper unit test for testing this actions. Do you think that attributes don't break srp or you just disregard this and think that it's simplest , is not worst way ? P.S. I read some likes articles and discussions and I just want to put things in proper order. P.P.S. sorry for my "fluent" english :=)

  • Jquery problem - cant expand the row above in a table

    - by apg1985
    Hi People, What I cant figure out is how I would toggle a row in a table using the one below it. So say I have a table with 2 rows the first contains content and the one below contains a button, when the page loads the content row is hidden and when you click the button it toggles the content row on and off. In the example the first table works but the second does not, I need the second one to work. <!DOCTYPE HTML> <html> <head> <title>Testing Horizontal Accordion</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $(".sectionhead").toggle( function() { $(this).next("tr").hide(); }, function() { $(this).next("tr").show(); } ) }); </script> </head> <body> <table> <tr class="sectionhead"><td></td></tr> <tr class="child"><td>child</td></tr> </table> <br> <table> <tr class="child"><td>child</td></tr> <tr class="sectionhead"><td></td></tr> </table> </body> </html>

  • does sfWidgetFormSelect provide a string or an int of the selected item?

    - by han
    Hey guys, I'm having an annoying problem. I'm trying to find out what fields of a form were changed, and then insert that into a table. I managed to var_dump in doUpdateObjectas shown in the following public function doUpdateObject($values) { parent::doUpdateObject($values); var_dump($this->getObject()->getModified(false)); var_dump($this->getObject()->getModified(true)); } And it seems like $this-getObject()-getModified seems to work in giving me both before and after values by setting it to either true or false. The problem that I'm facing right now is that, some how, sfWidgetFormSelect seems to be saving one of my fields as a string. before saving, that exact same field was an int. (I got this idea by var_dump both before and after). Here is what the results on both var dumps showed: array(1) {["annoying_field"]=> int(3)} array(1) {["annoying_field"]=>string(1)"3"} This seems to cause doctrine to think that this is a modification and thus gives a false positive. In my base form, I have under $this->getWidgets() 'annoying_field' => new sfWidgetFormInputText(), under $this->setValidators 'annoying_field' => new sfValidatorInteger(array('required' => false)), and lastly in my configured Form.class.php I have reconfigured the file as such: $this->widgetSchema['annoying_field'] = new sfWidgetFormSelect(array('choices' => $statuses)); statuses is an array containing values like {""a", "b", "c", "d"} and I just want the index of the status to be stored in the database. And also how can I insert the changes into another database table? let's say my Log table? Any ideas and advice as to why this is happen is appreciated, I've been trying to figure it out and browsing google for various keywords with no avail. Thanks! Edit: ok so I created another field, integer in my schema just for testing. I created an entry, saved it, and edited it. this time the same thing happened!

  • What are the worst examples of moral failure in the history of software engineering?

    Many computer science curricula include a class or at least a lecture on disasters caused by software bugs, such as the Therac-25 incidents or Ariane 5 Flight 501. Indeed, Wikipedia has a list of software bugs with serious consequences, and a question on StackOverflow addresses some of them too. We study the failures of the past so that we don't repeat them, and I believe that rather than ignoring them or excusing them, it's important to look at these failures squarely and remind ourselves exactly how the mistakes made by people in our profession cost real money and real lives. By studying failures caused by uncaught bugs and bad process, we learn certain lessons about rigorous testing and accountability, and we make sure that our innocent mistakes are caught before they cause major problems. There are kinds of less innocent failure in software engineering, however, and I think it's just as important to study the serious consequences caused by programmers motivated by malice, greed, or just plain amorality. Thus we can learn about the ethical questions that arise in our profession, and how to respond when we are faced with them ourselves. Unfortunately, it's much harder to find lists of these failures--the only one I can come up with is that apocryphal "DOS ain't done 'til Lotus won't run" story. What are the worst examples of moral failure in the history of software engineering?

  • GL_COLOR_MATERIAL with lighting on Android

    - by kostmo
    It appears that glColorMaterial() is absent from OpenGL ES. According to this post (for iPhone), you may still enable GL_COLOR_MATERIAL in OpenGL ES 1.x, but you're stuck with the default settings of GL_FRONT_AND_BACK and GL_AMBIENT_AND_DIFFUSE that you would otherwise set with glColorMaterial(). I would be OK with this, but the diffuse lighting is not working correctly. I set up my scene and tested it with one light, setting glMaterialfv() for GL_AMBIENT and GL_DIFFUSE once in the initialization. The normals have been set correctly, and lighting works the way it's supposed to. I see the Gourad shading. With GL_LIGHTING disabled, the flat colors I have set with glColor4f() appear on the various objects in the scene. This also functions as expected. However, when glEnable(GL_COLOR_MATERIAL) is called, the flat colors remain. I would expect to see the lighting effects. What might be missing? glColorMaterial() is also mentioned on anddev.org, but I'm not sure if the information there is accurate. I'm testing this on an Android 2.1 handset (Motorola Droid). Edit: It works properly on my 1.6 handset (ADP1).

  • Have to login twice. PHP sessions and login troubles with Chrome and Opera.

    - by Robert
    The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10). Here is the stripped down code that I am testing on: Login Page: session_start(); $_SESSION['user_id'] = 8; $_SESSION['user_name'] = 'Jim'; session_write_close(); header('Location: http://www.my-domain-name.com/'); exit(); Home Page: session_start(); if ( isset($_SESSION['user_id']) ) { echo "You are logged in!"; } else { echo "You are NOT logged in!"; } Logout Page: session_start(); session_unset(); session_destroy(); header('Location: http://www.my-domain-name.com/'); exit(); Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas? Thanks for your help.

  • super light software development process

    - by Walty
    hi, For the development process I have involved so far, most have teams of SINGLE member, or occasionally two. We used python + django for the major development, the development process is actually very fast, and we do have code reviews, design pattern discussions, and constant refactoring. Though team size is small, I do think there are some development processes / best practices that could be enforced. For example, using svn would be definitely better than regular copy backup. I did read some articles & books about Agile, XP & continuous integration, I think they are nice, but still too heavy for this case (team of 1 or 2, and fast coding). For example, IMHO, with nice design pattern, and iterative development + refactoring, the TDD MIGHT be an overkill, or at least the overhead does not out-weight the advantages. And so is the pair programming. The automated testing is a nice idea, but it seems not technically feasible for every project. our current practices are: svn + milestone + code review I wonder if there are development processes / best practices specifically targeted on such super light teams? thanks.

  • Why doesn't my test run tearDownAfterTestClass when it fails

    - by Memor-X
    in a test i am writing the setUpBeforeTests creates a new customer in the database who is then used to perform the tests with so naturally when i finish the test i should get rid of this test customer in tearDownAfterTestClass so that i can create then anew when i rerun the test and not get any false positives how when the tests all run fine i have no problem but if a test fails and i go to rerun it my setUpBeforeTests fails because i check for mysql errors in it like this try { if(!mysqli_query($connection,$query)) { $this->assertTrue(false); } } catch (Exception $exc) { $msg = '[tearDownAfterTestClass] Exception Error' . PHP_EOL . PHP_EOL; $msg .= 'Could not run query - '.mysqli_error($connection). PHP_EOL;; $this->fail($msg); } the error i get is that there is a primary key violation which is expected cause i'm trying to create a new customer using the same data (primary key is on email which is also used to log in) however that means when the test failed it didn't run tearDownAfterTestClass now i could just move everything in tearDownAfterTestClass to the start of setUpBeforeTests however to me that seems like bad programming since it defeates the purpose of even have tearDownAfterTestClass so i am wondering, why isn't my tearDownAfterTestClass running when a test fails NOTE: the database is a fundamental part of the system i'm testing and the database and system are on a separate development environment not the live one, the backup files for the database are almost 2 GBs and takes almost 1/2 an hour to restore, the purpose of the tear down is to remove any data we have added because of the test so that we don't have to restore the database every time we run the tests
