• I'm trying to install psycopg2 onto Mac OS 10.6.3; it claims it can't find "stdarg.h" but I can see

  - by cojadate

  I'm desperately trying to successfully install psycopg2 but keep running into errors. The latest one seems to involve it not being to find "stdarg.h" (see code below). However I can see with my own eyes that a file called stdarg.h exists at /Developer/SDKs/MacOSX10.4u.sdk/usr/include/stdarg.h (where it claims it can't find anything) so I've no idea what to do about it. I'm running Mac OS 10.6.3 and within the last few days I've made sure I have all the latest OS developer tools. I have Python 2.6.2 and PostgreSQL 8.4 if that makes any difference. python setup.py install running install running build running build_py running build_ext building 'psycopg2._psycopg' extension creating build/temp.macosx-10.3-fat-2.6 creating build/temp.macosx-10.3-fat-2.6/psycopg gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -fno-strict-aliasing -fno-common -dynamic -DNDEBUG -g -O3 -DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.2.1 (dt dec ext pq3)" -DPG_VERSION_HEX=0x080404 -DPSYCOPG_EXTENSIONS=1 -DPSYCOPG_NEW_BOOLEAN=1 -DHAVE_PQFREEMEM=1 -DHAVE_PQPROTOCOL3=1 -I/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6 -I. -I/opt/local/include/postgresql84 -I/opt/local/include/postgresql84/server -c psycopg/psycopgmodule.c -o build/temp.macosx-10.3-fat-2.6/psycopg/psycopgmodule.o In file included from /Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/unicodeobject.h:4, from /Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/Python.h:85, from psycopg/psycopgmodule.c:27: /Developer/SDKs/MacOSX10.4u.sdk/usr/include/stdarg.h:4:25: error: stdarg.h: No such file or directory In file included from /Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/unicodeobject.h:4, from /Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/Python.h:85, from psycopg/psycopgmodule.c:27: /Developer/SDKs/MacOSX10.4u.sdk/usr/include/stdarg.h:4:25: error: stdarg.h: No such file or directory lipo: can't figure out the architecture type of: /var/folders/MQ/MQ-tWOWWG+izzuZCrAJpzk+++TI/-Tmp-//ccakFhRS.out error: command 'gcc' failed with exit status

• Hazelcast Distributed Executor Service KeyOwner

  - by János Veres

  I have problem understanding the concept of Hazelcast Distributed Execution. It is said to be able to perform the execution on the owner instance of a specific key. From Documentation: <T> Future<T> submitToKeyOwner(Callable<T> task, Object key) Submits task to owner of the specified key and returns a Future representing that task. Parameters: task - task key - key Returns: a Future representing pending completion of the task I believe that I'm not alone to have a cluster built with multiple maps which might actually use the same key for different purposes, holding different objects (e.g. something along the following setup): IMap<String, ObjectTypeA> firstMap = HazelcastInstance.getMap("firstMap"); IMap<String, ObjectTypeA_AppendixClass> secondMap = HazelcastInstance.getMap("secondMap"); To me it seems quite confusing what documentation says about the owner of a key. My real frustration is that I don't know WHICH - in which map - key does it refer to? The documentation also gives a "demo" of this approach: import com.hazelcast.core.Member; import com.hazelcast.core.Hazelcast; import com.hazelcast.core.IExecutorService; import java.util.concurrent.Callable; import java.util.concurrent.Future; import java.util.Set; import com.hazelcast.config.Config; public void echoOnTheMemberOwningTheKey(String input, Object key) throws Exception { Callable<String> task = new Echo(input); HazelcastInstance hz = Hazelcast.newHazelcastInstance(); IExecutorService executorService = hz.getExecutorService("default"); Future<String> future = executorService.submitToKeyOwner(task, key); String echoResult = future.get(); } Here's a link to the documentation site: Hazelcast MultiHTML Documentation 3.0 - Distributed Execution Did any of you guys figure out in the past what key does it want?

• How to test a struts 2.1.x developer?

  - by Jason Pyeron

  We employ test to filter out those who can't. The tests are designed to be very low effort for those who can and too much effort for those who can't. Here is an example for java web application developer on an Oracle project: We only work with contractors who can use the tools we use, to determine if you can use the tools we have devised some very simple tests. Instructions If you are prepared and knowledgeable this will take you about 2-5 minutes. Suggested knowledge and tools: * subversion 1.6 see http://subversion.tigris.org/ or http://cygwin.com/setup.exe * java 1.6 see http://java.sun.com/javase/downloads/index.jsp * oracle >=10g see http://www.oracle.com/technology/software/products/jdev/index.html * j2ee server see http://tomcat.apache.org/download-55.cgi or http://www.jboss.org/jbossas/downloads/ Steps 1. check out svn://statics32.pdinc.us/home/subversion/guest 2. deploy the war file found at trunk/test.war 3. browse to the web application you installed from the war file and answer the one SQL question: How many rows are in the table 'testdata' where column 'value' ends with either an 'A' or an 'a'? The login credentials are in trunk/doc/oracle.txt 4. make a RESULTS HASH by submitting your answer to the form. 5. create a file in tmp/YourUserName.txt and put the RESULTS HASH in it, not the answer. 6. check in your file (don't forget to add the file first). 7. message me with the revision number of your check in. As such I am looking for ideas on how to test for someone to be a struts 2.1 w/ annotations.

• How do display a UserControl with satisfying all imports

  - by Yost

  Dear SO, I'm having some issues with Silverlight 4/ MEF. I have a basic framework setup with a Silverlight Navigation app at the core. Image link to the diagram for clarification The main app (Desu) contains some pages and controls that export en import nicely. I dynamicly load controls from Desu.Controls(like an imageviewer which i identify with the IImageViewer interface) and some pages from Desu.Pages. The first problem I had was with dynamicly loading pages and being able to navigate to these pages (eg. use dummyhttp://blagh/desutestpage.aspx#/Activation when Desu.Pages was loaded from the xap). I solved this by using a custom MetaAttribute and a custom contentloader. Now for the question part: I want to load the ImageViewerControl from Desu.Controls in HomePage in Desu. I haven't loaded the Desu.Controls into the package though. When i try to load the control it gives me CompositionException because it can't satisfy the ImageViewControl import. I tried setting AllowRecomposition=true but that didn't help. So is it possible to load a control without satisfying all imports and, if yes, how does one do this?

• MVC2 Areas not Registering Correctly

  - by Geoffrey

  I believe I have my Areas setup correctly (they were working in MVC1 fine). I followed the guide here: http://odetocode.com/Blogs/scott/archive/2009/10/13/asp-net-mvc2-preview-2-areas-and-routes.aspx I've also used Haacked's Route Debugger. Which shows the correct Area/Controller registration when I run it. However when I try to go to my (AreaName)/(Controller) I get this error: "The resource cannot be found." I believe this indicates there's a problem with the routing, but I'm having trouble debugging this. Where should I set my breakpoints to catch routing errors in MVC2? I'm also using SparkViewEngine compiled against MVC2 references. Could this possibly be causing this error? I've set breakpoints on the controller in the area and it never fires off, I assumed the view engine doesn't kick in until after the controller has been initiated, but I could be wrong. The non-area landing page works fine, and I've stripped my project of all areas except one, to avoid any sort of naming conflicts. Any ideas where I can try to look next?

• Flipping View transition becomes clunky when using UIPickerViews with a large number of elements

  - by user302246

  I have a very simple app created with the Utility Application project template on XCode. My MainView has two UIPickerView components and two buttons. The FlipSideView has another UIPickerView. The pickers on the main view each have 4 segments and each segment has 8 rows. The picker on the flip side has just 1 segment with 8 rows. All rows on all pickers are just text. With just this setup, pressing the button to flip the view back and forth displays a noticeable delay before the animation actually starts, and then the animation actually seems to go faster than what it should, like it's trying to make up for the lost time. I removed the pickers in interface builder and loaded the app on the phone and the animation now seems natural. I also tried just one picker (the flipside one) and things still seem normal. So my current theory is that the number of objects involved in the main view is the cause. The thing is that I don't think it's that many (4 x 8 x 2 = 64), but I could be completely wrong. This is pretty much my first app so maybe I'm just doing something grossly wrong, or maybe the phone is has a lot more limited processing than I thought. I am thinking of creating the picker views with pickerView:viewForRow:forComponent:reusingView: to see if this hopefully performs better, but I'm not sure if this is just a waste of time. Any suggestions? Thanks Ruy P.S.: Testing on a 3G phone on 3.1.2

• Scope of This JavaScript Variable

  - by dkris

  I have a question and an issue wrt the code below: My question is what is the scope of the variable loaded here. The reason why i ask this is the onload="if(loaded==1)inittextarea() code is working fine on Firefox and not IE8. Why is this happening? Is there something specific i need to do here? Or is it not a valid practice? <html> <head> <title>Some Page</title> <link rel="stylesheet" href="../css/default.css" type="text/css"> <script type="text/javascript"> var loaded = 0; /*Point of interest*/ function jsLoaded() { loaded =1; } </script> <script type="text/javascript"> function inittextarea() { alert("test") tinyMCE.init({ elements : "content", theme : "advanced", readonly : true, mode : "exact", theme : "advanced", readonly : true, setup : function(ed) { ed.onInit.add(function() { tinyMCE.activeEditor.execCommand("mceToggleVisualAid"); }); } }); } </script> <script src="../js/tiny_mce/tiny_mce.js" onload="jsLoaded()" type="text/javascript"></script> </head> <body onload="if(loaded==1)inittextarea()"><!--Works on Firefox only--> *Usual stuff* </body></html> Any pointers please?

• DesignTime data not showing in Blend when bound against CollectionViewSource

  - by bitbonk

  I have datatemplate for a viewmodel where an itemscontrol is bound again a CollectionViewSource (to enable sorting in xaml). <DataTemplate x:Key="equipmentDataTemplate"> <Viewbox> <Viewbox.Resources> <CollectionViewSource x:Key="viewSource" Source="{Binding Modules}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="ID" Direction="Ascending"/> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Viewbox.Resources> <ItemsControl ItemsSource="{Binding Source={StaticResource viewSource}}" Height="{DynamicResource equipmentHeight}" ItemTemplate="{StaticResource moduleDataTemplate}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </Viewbox> </DataTemplate> I have also setup the UserControl where all of this is defined to provide designtime data d:DataContext="{x:Static vm:DesignTimeHelper.Equipment}"> This is basically a static property that gives me an EquipmentViewModel that has a list of ModuleViewModels (Equipment.Modules). Now as long as I bind to the CollectionViewSource the designtime data does not show up in blend 3. When I bind to the ViewModel collection directly <ItemsControl ItemsSource="{Binding Modules}" I can see the designtime data. Any idea what I could do?

• Weird .net 4.0 exception when running unit tests

  - by vdh_ant

  Hi guys I am receiving the following exception when trying to run my unit tests using .net 4.0 under VS2010 with moq 3.1. Attempt by security transparent method 'SPPD.Backend.DataAccess.Test.Specs_for_Core.When_using_base.Can_create_mapper()' to access security critical method 'Microsoft.VisualStudio.TestTools.UnitTesting.Assert.IsNotNull(System.Object)' failed. Assembly 'SPPD.Backend.DataAccess.Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception. The test I am running is really straight forward and looks something like the following: [TestMethod] public void Can_create_mapper() { this.SetupTest(); var mockMapper = new Moq.Mock<IMapper>().Object; this._Resolver.Setup(x => x.Resolve<IMapper>()).Returns(mockMapper).Verifiable(); var testBaseDa = new TestBaseDa(); var result = testBaseDa.TestCreateMapper<IMapper>(); Assert.IsNotNull(result); //<<< THROWS EXCEPTION HERE Assert.AreSame(mockMapper, result); this._Resolver.Verify(); } I have no idea what this means and I have been looking around and have found very little on the topic. The closest reference I have found is this http://dotnetzip.codeplex.com/Thread/View.aspx?ThreadId=80274 but its not very clear on what they did to fix it... Anyone got any ideas?

• delivery mechanism, Rational ClearCase

  - by kadaba

  Hi All, We came up with a stream structure for the Rational ClearCase UCM model. We recently migrated the code base into the new setup. We had three different code bases, i.e. three physical code bases. The way migration was done in this way. we moved the production code first, created a baseline. Then the uat code and created a baseline and then the development code and created a baseline. As of now the integration stream has the latest baseline that is the development baseline. Now we have other two streams for the prd and the uat from which the release will be done in the respective environments. I have my dev stream now. I create an activity and make some changes. now I need to promote these changes into the uat environment. If I deliver the changes to the integration stream, merge is done but on a development basline. I do not want to rebase it to uat as many development apps wil get rebased into the uat which is not desired. How do I achieve promoting changes to the uat environment(uat stream). kindly advice.

• WM_NCHITTEST and secondary monitor to left of primary monitor

  - by AlanKley

  The described setup with 2nd monitor to left of primary causes WM_NCHITTEST to send negative values which is apparently not supported according to this post. I have a custom control written in win32 that is like a Group control. It has a small clickable area. No MOUSE events are coming to my control when the window containing the custom control lies on a second monitor to the left of the primary monitor. SPY++ shows WM_NCHITTEST messages but no Mouse messages. When window is moved to primary monitor or secondary monitor is positioned to right of primary (all points are positive) then everything works fine. Below is how the WM_NCHITTEST is handled in my custom control. In general I need it to return HTTRANSPARENT so as not to obscure other controls placed inside of it. Anybody have any suggestions what funky coordinate translation I need to do and what to return in response to WM_NCHITTEST to get Mouse messages translated and sent to my control in the case where it is on a 2nd monitor placed to the left of the primary monitor? case WM_NCHITTEST: { POINT Pt = {LOWORD(lP), HIWORD(lP)}; int i; ScreenToClient (hWnd, &Pt); if (PtInRect (&rClickableArea, Pt)) { return(DefWindowProc( hWnd, Msg, wP, lP )); } } lReturn = HTTRANSPARENT; break;

• NHibernate Child items query using Parent Id

  - by thorkia

  So I have a set up similar to this questions: Parent Child Setup Everything works great when saving the parent and the children. However, I seem to have a problem when selecting the children. I can't seem to get all the children with a specific parent. This fails with: NHibernate.QueryException: could not resolve property: ParentEntity_id of: Test.Data.ChildEntity Here is my code: public IEnumerable<ChildEntity> GetByParent(ParentEntity parent) { using (ISession session = OrmHelper.OpenSession()) { return session.CreateCriteria<ChildEntity>().Add(Restrictions.Eq("ParentEntity_id ", parent.Id)).List<ChildEntity>(); } } Any help in building a proper function to get all the items would be appreciated. Oh, I am using Fluent NHibernate to construct the mappings - version 1 RTM and NHibernate 2.1.2 GA If you need more information, let me know. As per you request, my fluent mappings: public ParentEntityMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Code).UniqueKey("ukCode"); HasMany(x => x.ChildEntity).LazyLoad() .Inverse().Cascade.SaveUpdate(); } public ChildEntityMap() { Id(x => x.Id); Map(x => x.Amount); Map(x => x.LogTime); References(x => x.ParentEntity); } That maps to the following 2 tables: CREATE TABLE "ParentEntity" ( Id integer, Name TEXT, Code TEXT, primary key (Id), unique (Code) ) CREATE TABLE "ChildEntity" ( Id integer, Amount NUMERIC, LogTime DATETIME, ParentEntity_id INTEGER, primary key (Id) ) The data store in SQLite.

• How to restrain one's self from the overwhelming urge to rewrite everything?

  - by Scott Saad

  Setup Have you ever had the experience of going into a piece of code to make a seemingly simple change and then realizing that you've just stepped into a wasteland that deserves some serious attention? This usually gets followed up with an official FREAK OUT moment, where the overwhelming feeling of rewriting everything in sight starts to creep up. It's important to note that this bad code does not necessarily come from others as it may indeed be something we've written or contributed to in the past. Problem It's obvious that there is some serious code rot, horrible architecture, etc. that needs to be dealt with. The real problem, as it relates to this question, is that it's not the right time to rewrite the code. There could be many reasons for this: Currently in the middle of a release cycle, therefore any changes should be minimal. It's 2:00 AM in the morning, and the brain is starting to shut down. It could have seemingly adverse affects on the schedule. The rabbit hole could go much deeper than our eyes are able to see at this time. etc... Question So how should we balance the duty of continuously improving the code, while also being a responsible developer? How do we refrain from contributing to the broken window theory, while also being aware of actions and the potential recklessness they may cause? Update Great answers! For the most part, there seems to be two schools of thought: Don't resist the urge as it's a good one to have. Don't give in to the temptation as it will burn you to the ground. It would be interesting to know if more people feel any balance exists.

• is mysql index useful on column 'state' when only doing bit-operations on the column?

  - by Geert-Jan

  I have a lot of domain entities (stored in mysql) which undergo lots of different operations. Each operation is executed from a different program. I need to keep (flow)-state for these entities which I implemented in as a long field 'flowstate' used as a bitset. to query mysql for entities which have undergone a certain operation I do something like: select * from entities where state >> 7 & 1 = 1 Indicating bit 7 (cooresponding to operation 7) has run. (<-- simplified) Anyway, I really didn't pay attention to the performance implications of this setup in the beginning, and I think I'm in a bit of trouble since queries as the above run pretty slow. What I'd like to know: Does an mysql index on 'flowstate' help at all? After all it's not a single value Mysql can quickly find using a binary sort or whatever. If it doesn't, are there any other things I could do to speed things up? . Are there special 'mask-indices' for fields with use-cases as the above? TIA, Geert-jan

• Django: Overriding the save() method: how do I call the delete() method of a child class

  - by Patti

  The setup = I have this class, Transcript: class Transcript(models.Model): body = models.TextField('Body') doPagination = models.BooleanField('Paginate') numPages = models.PositiveIntegerField('Number of Pages') and this class, TranscriptPages(models.Model): class TranscriptPages(models.Model): transcript = models.ForeignKey(Transcript) order = models.PositiveIntegerField('Order') content = models.TextField('Page Content', null=True, blank=True) The Admin behavior I’m trying to create is to let a user populate Transcript.body with the entire contents of a long document and, if they set Transcript.doPagination = True and save the Transcript admin, I will automatically split the body into n Transcript pages. In the admin, TranscriptPages is a StackedInline of the Transcript Admin. To do this I’m overridding Transcript’s save method: def save(self): if self.doPagination: #do stuff super(Transcript, self).save() else: super(Transcript, self).save() The problem = When Transcript.doPagination is True, I want to manually delete all of the TranscriptPages that reference this Transcript so I can then create them again from scratch. So, I thought this would work: #do stuff TranscriptPages.objects.filter(transcript__id=self.id).delete() super(Transcript, self).save() but when I try I get this error: Exception Type: ValidationError Exception Value: [u'Select a valid choice. That choice is not one of the available choices.'] ... and this is the last thing in the stack trace before the exception is raised: .../django/forms/models.py in save_existing_objects pk_value = form.fields[pk_name].clean(raw_pk_value) Other attempts to fix: t = self.transcriptpages_set.all().delete() (where self = Transcript from the save() method) looping over t (above) and deleting each item individually making a post_save signal on TranscriptPages that calls the delete method Any ideas? How does the Admin do it? UPDATE: Every once in a while as I'm playing around with the code I can get a different error (below), but then it just goes away and I can't replicate it again... until the next random time. Exception Type: MultiValueDictKeyError Exception Value: "Key 'transcriptpages_set-0-id' not found in " Exception Location: .../django/utils/datastructures.py in getitem, line 203 and the last lines from the trace: .../django/forms/models.py in _construct_form form = super(BaseInlineFormSet, self)._construct_form(i, **kwargs) .../django/utils/datastructures.py in getitem pk = self.data[pk_key]

• How to organize live data integrity tests and code unit tests?

  - by karlthorwald

  I have several files with code testing code (which uses a "unittest" class). Later I found it would be nice to test database integrity also. I put this into a separate directory tree. (Things like the keys have correct format, parent and child nodes are pointing correctly and such.) I use the same unittest class for the integrity tests. Now I wonder if it makes really sense to keep this separate. To test the integrity of data I often duplicate parts of code that I use to test the code that handles the data. But it is not the same. The code tests use test databases (that get deleted after each test) and the integrity tests connect to the live data and analyze it. The integrity tests I want to call from cron and send an alarm if something happens in the live database. How would you handle that? Are there standards for such a setup? What is your experience? My tendency is to put everything in the same file, which would result in the code tests also being executed by the cron on the production environment.

• Getting size of a specific byte array from an array of pointers to bytes

  - by Pat James

  In the following example c code, used in an Arduino project, I am looking for the ability to get the size of a specific byte array within an array of pointers to bytes, for example void setup() { Serial.begin(9600); // for debugging byte zero[] = {8, 169, 8, 128, 2,171,145,155,141,177,187,187,2,152,2,8,134,199}; byte one[] = {8, 179, 138, 138, 177 ,2,146, 8, 134, 8, 194,2,1,14,199,7, 145, 8,131, 8,158,8,187,187,191}; byte two[] = {29,7,1,8, 169, 8, 128, 2,171,145,155,141,177,187,187,2,152,2,8,134,199, 2, 2, 8, 179, 138, 138, 177 ,2,146, 8, 134, 8, 194,2,1,14,199,7, 145, 8,131, 8,158,8,187,187,191}; byte* numbers[3] = {zero, one, two }; function(numbers[1], sizeof(numbers[1])/sizeof(byte)); //doesn't work as desired, always passes 2 as the length function(numbers[1], 25); //this works } void loop() { } void function( byte arr[], int len ) { Serial.print("length: "); Serial.println(len); for (int i=0; i<len; i++){ Serial.print("array element "); Serial.print(i); Serial.print(" has value "); Serial.println((int)arr[i]); } } In this code, I understand that sizeof(numbers1)/sizeof(byte)) doesn't work because numbers1 is a pointer and not the byte array value. Is there a way in this example that I can, at runtime, get at the length of a specific (runtime-determined) byte array within an array of pointers to bytes? Understand that I am limited to developing in c (or assembly) for an Arduino environment. Also open to other suggestions rather than the array of pointers to bytes. The overall objective is to organize lists of bytes which can be retrieved, with length, at runtime.

  My dev environment is Win XP SP2 / Apache 2.something PHP 5.something_or_other My prod env is Linux Ubuntu / Apache 2.something_else PHP 5.something_or_other_else The code is all Zend Framework Version: 1.11.1 I can telnet to: smtp.gmail.com 465 from the PC. I have Mercury configured on my PC to use gmail as it's smtp host and it works just fine. (MercuryC SMTP Client). Mercury is set to use port 465 and SSL on smtp.gmail.com -- No problem. Zend mail works just fine on my production environment using the production mail server to send out mail. It's the same basic application.ini but with different values in the mail variables. On my local PC dev setup, my application.ini contains: (same values as I use in Mercury) mail.templatePath = APPLICATION_PATH "/emails" mail.sender.name = "myAccount" mail.sender.email = "[email protected]" mail.host = smtp.gmail.com mail.smtp.auth = "login" mail.smtp.username = "[email protected]" mail.smtp.password = "myPassWord" mail.smtp.ssl = "ssl" mail.smtp.port = 465 I have been doing trial and error for hours trying to get a single email out with no success. In every case, regardless of server or port settings it throws an error and reports: Could not open socket. Both Apache and Mercury Core are exceptions in my Windows Firewall config. Mercury seems to be having no problem. I have searched stackoverflow before posting this and have been googling for hours -- with no success. I am slowly losing my mind I would be very much obliged for any tip as to what might be wrong. Thanks for reading. =================== BTW When I use the SAME application.ini values on my local PC as on the production host, I get the same "Could not open socket" error. Those values are: mail.templatePath = APPLICATION_PATH "/emails" mail.sender.name = "otherUser" mail.sender.email = "[email protected]" mail.host = smtp.otherServer.com mail.smtp.auth = "login" mail.smtp.username = "[email protected]" mail.smtp.password = "otherPAssWord" mail.smtp.ssl = "ssl" mail.smtp.port = 465 I know these work in the production (Ubuntu) environment. I'm utterly baffled.

• Why won't my styles show in a Dynamics CRM 4 IFRAME?

  - by Dan Crowther

  I have created a web page (ASP.NET) that includes a stylesheet to mimic Dynamics CRM styles. This is to be used in a CRM IFRAME (within a form). The stylesheet is referenced as follows: <head id="Head1" runat="server"> <link href="Styles.css" rel="stylesheet" type="text/css" /> </head> When I load the page in Visual Studio, all is well. When I load it in CRM, none of the styles are shown and no images are displayed. If I browse directly to the image, I get a 404 error. However, the pages function correctly. I have set read permissions for "Everyone" on the server to see if that was causing a problem but it didn't help. I also tried putting a plain HTML page in the folder and that won't load either - again a 404. The page is installed in the ISV folder ..../isv/MyProject. Can anyone help? EDIT This is on a multi-tenancy system. On my test company (testcompany) if I browse to http://crm/testcompany/isv/MyProject/MyPage.aspx, the page is loaded (without styles and images). If I browse to http://crm/testcompany/isv/MyProject/TestImage.gif, the image is not shown. If I browse to http://crm/isv/MyProject/TestImage.gif, the image is shown. Does this suggest a problem with the server setup and the way CRM messes around with virtual directories?

• A way to specify a different host in an SSH tunnel from the host in use

  - by Tom

  I am trying to setup an SSH tunnel to access Beanstalk (to bypass an annoying proxy server). I can get this to work, but with one caveat: I have to map my Beanstalk host URL (username.svn.beanstalkapp.com) in my hosts file to 127.0.0.1 (and use the ip in place of the domain when setting up the tunnel). The reason (I think) is that I am creating the tunnel using the local SSH instance (on Snow Leopard) and if I use localhost or 127.0.0.1 when talking to Beanstalk, it rejects the authorisation credentials. I believe this is because Beanstalk use the hostname specified in a request to determine which account the username / password combination should be checked against. If localhost is used, I think this information is missing (in some manner which Beanstalk requires) from the requests. At the moment I dig the IP for username.svn.beanstalkapp.com, map username.svn.beanstalkapp.com to 127.0.0.1 in my hosts file, then for the tunnel I use the command: ssh -L 8080:ip:443 -p 22 -l tom -N 127.0.0.1 I can tell Subversion that the repo. is located at: https://username.svn.beanstalkapp.com:8080/repo-name This uses my tunnel and the username and password are accepted. So, my question is if there is an option when setting up the SSH tunnel which would mean I wouldn't have to use my hosts file workaround?

• Code Access Security and Sharepoint WebParts

  - by Gordon Carpenter-Thompson

  I've got a vague handle on how Code Access Security works in Sharepoint. I have developed a custom webpart and setup a CAS policy in my Manifest <CodeAccessSecurity> <PolicyItem> <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for Okana"> <IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" version="1" ObjectModel="True" Impersonate="True" /> <IPermission class="SecurityPermission" version="1" Flags="Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration" /> <IPermission class="AspNetHostingPermission" version="1" Level="Medium" /> <IPermission class="DnsPermission" version="1" Unrestricted="true" /> <IPermission class="EventLogPermission" version="1" Unrestricted="true"> <Machine name="localhost" access="Administer" /> </IPermission> <IPermission class="EnvironmentPermission" version="1" Unrestricted="true" /> <IPermission class="System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" version="1" Unrestricted="true"/> <IPermission class="System.Net.WebPermission, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Unrestricted="true" /> <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" PathDiscovery="*AllFiles*" /> <IPermission class="IsolatedStorageFilePermission" version="1" Allowed="AssemblyIsolationByUser" UserQuota="9223372036854775807" /> <IPermission class="PrintingPermission" version="1" Level="DefaultPrinting" /> <IPermission class="PerformanceCounterPermission" version="1"> <Machine name="localhost"> <Category name="Enterprise Library Caching Counters" access="Write"/> <Category name="Enterprise Library Cryptography Counters" access="Write"/> <Category name="Enterprise Library Data Counters" access="Write"/> <Category name="Enterprise Library Exception Handling Counters" access="Write"/> <Category name="Enterprise Library Logging Counters" access="Write"/> <Category name="Enterprise Library Security Counters" access="Write"/> </Machine> </IPermission> <IPermission class="ReflectionPermission" version="1" Unrestricted="true"/> <IPermission class="SecurityPermission" version="1" Flags="SerializationFormatter, UnmanagedCode, Infrastructure, Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration, ControlAppDomain,ControlDomainPolicy" /> <IPermission class="SharePointPermission" version="1" ObjectModel="True" /> <IPermission class="SmtpPermission" version="1" Access="Connect" /> <IPermission class="SqlClientPermission" version="1" Unrestricted="true"/> <IPermission class="WebPartPermission" version="1" Connections="True" /> <IPermission class="WebPermission" version="1"> <ConnectAccess> <URI uri="$OriginHost$"/> </ConnectAccess> </IPermission> </PermissionSet> <Assemblies> .... </Assemblies> This is correctly converted into a wss_custom_wss_minimaltrust.config when it is deployed onto the Sharepoint server and mostly works. To get the WebPart working fully, however I find that I need to modify the wss_custom_wss_minimaltrust.config by hand after deployment and set Unrestricted="true" on the permissions set <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1"> to <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1" Unrestricted="true"> It's all because I'm loading a User Control from the webpart. I don't believe there is a way to enable that using CAS but am willing to be proven wrong. Is there a way to set something in the manifest so I don't need to make this fix by hand? Thanks

• Django apache-wsgi configuration problem

  - by omat

  Hi, I am trying to get my Django project running on the production server. I setup the environment using pip, so it is identical to the development environment where everything is running fine. The only difference is that I don't use virtualenv on production, because this project is the only one that is going to run on production. Also on production, there is an Nginx reverse proxy to serve static content, and passes dynamic requests to Apache2. The Apache wsgi file is as follows: import sys, os sys.path.append('/home/project/src') os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() When I access the server, I get an import error: ImproperlyConfigured: Error importing middleware middleware: "cannot import name UserProfile" Which refers to the middleware.py under src/ folder which is referred by the settings. But I can import both the middleware and the UserProfile class from within ./manage.py shell prompt. It seems like a problem with paths in wsgi file but I cannot see what. The directory structure is: /home/project /home/project/src (which contains the settings.py, middleware.py and app folders) /home/apache/apache.wsgi Any help is greatly appreciated. Thanks, oMat

• How do ASP.NET MVC Routes work?

  - by Pure.Krome

  Hi folks, imagine i have the following route setup... public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); // Added custom route here! routes.MapRoute( "CatchAll", "{*catchall}," new { controller = "Error", action = "NotFound" } ); } nothing new - that's the default ASP.NET MVC1 RegisterRoutes method, with one custom route added. Now, if I goto the following url, i get a 404... http://whatever/Home/MissingActionMethod So there's no ActionMethod called MissingActionMethod in the HomeController. So, does this mean, if i goto the 1st route defined, above .. and fail to find an action .. do I then come back and try the second route? rinse-repeat? Or once i match a route, i then try and execute that route .. and if i fail (ie, find the action is missing) .. then .. bad luck? boomski? cheers!
