• UITableViewCells of different heights place their accessoryViews at different X positions

  - by Jasarien

  Hey Guys, My app has some table cells that vary in height. The cells can also have a UIButton set to be a detail disclosure button (round, blue with arrow) as their accessory view. Depending on the height of the cell, the accessory view is positioned differently. At first I thought it was my layout code for my cell that was causing the problem, so I set up a quick independent test that uses vanilla UITableCells to remove the possibility that it could be my fault. I set up a view in interface builder, and just added a view table cells to the view, set their heights to different values and then added a detail disclosure button to each. Nothing more, nothing less. This is what I see: I added the size guides (thanks to Xscope) so you can see the difference in the accessory view x positions. The heights are: top 37px mid 68px bottom 44px (default, untouched height) If I increase the height any heigher than 68px the accessory view doesn't move any further to the left. Is this a bug? Is there any way I can prevent this from happening?

• Buttons OnClick Event not firing when it causes a textboxes onChange event to fire first

  - by user48408

  I have a few textboxes and button to save their values on a webpage. The onchange event of the textboxes fires some js which adds the changed text to a js array. The ok button when clicked flushes this to the database via a webservice. This works fine except when the onchange event is caused by clicking the ok button. In this scenario the onchange of the textboxes still fires but the onClick event of the button does not. Any ideas? textboxes look something like <input name="ctrlJPView$tbcTabContainer$Details$JP_Details_Address2Text" type="text" value="test" id="ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text" onchange="addSaveDetails('Jobs###' + document.getElementById('ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text').value + ');" style="font-size:8pt;Left:110px;Top:29px;Width:420px;Height:13px;Position:absolute;" /> My save button <input type="button" name="ctrlJPView$btnOk" value="OK" onclick="saveAmendments();refreshJobGrids();return false;__doPostBack('ctrlJPView$btnOk','')" id="ctrlJPView_btnOk" class="ControlText" style="width:60px;" /> UPDATE: I guess this comes down to one of two things. 1) Something is happening before the onClick of the button gets called to surpress that call such as an inadvertent return false; or 2) the onClick event isn't firing at all. Now I've rem'd out everything actually inside the functions that are being called beforehand but the problem persists. But if i remove the call altogether it works (???)

• Google map API v3 event click raise when clickingMarkerClusterer?

  - by lucian.jp

  I have a Google Map API v3 map object on a page that uses MarkerClusterer. I have a function that need to run when we click on the map to it is registered as: google.maps.event.addListener(map, 'click', function (event) { CallMe(event.latLng); }); So my problem is as follows: When I click on a cluster of MarkerClusterer instead of behaving like a marker and not raise the click event on the map but only the one from the marker it calls the click from the map. To test this I have generated an alert from the markerclusterer click: google.maps.event.addListener(markerClusterer, "clusterclick", function (cluster) { alert('MarkerClusterer click event'); }); So the clusterclick rises after the click event of map object. I then can't remove the listener of map object as a solution. Is there any way to test if there was a clusterer click in the click event of the map? Or a way to replicate the marker behaviour and do not raise the click event of map when clustererclick is called? Google and documentation didn’t help me. Thx

• WMI Query Script as a Job

  - by Kenneth

  I have two scripts. One calls the other with a list of servers as parameters. The second query is designed to execute a WMI query. When I run it manually, it does this perfectly. When I try to run it as a job it hangs forever and I have to remove it. For the sake of space here is the relevant part of the calling script: ProcessServers.ps1 Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList $sqlsrv,$destdb,$server,$instance GetServerDetailsLight.ps1 param($sqlsrv,$destdb,$server,$instance) $password = get-content C:\SQLPS\auth.txt | convertto-securestring $credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "DOMAIN\MYUSER",$password [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') $box_id = 0; if ($sqlsrv.length -eq 0) { write-output "No data passed" break } function getinfo { param( [string]$svr, [string]$inst ) "Entered GetInfo with: $svr,$inst" $cs = get-wmiobject win32_operatingsystem -computername $svr -credential $credentials -authentication 6 -Verbose -Debug | select Name, Model, Manufacturer, Description, DNSHostName, Domain, DomainRole, PartOfDomain, NumberOfProcessors, SystemType, TotalPhysicalMemory, UserName, Workgroup write-output "WMI Results: $cs" } getinfo $server $instance write-output "Complete" Executed as a job it will show as 'running' forever: PS C:\sqlps> Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList DBSERVER,LOGDB,SERVER01,SERVER01 Id Name State HasMoreData Location Command -- ---- ----- ----------- -------- ------- 21 Job21 Running True localhost param($sqlsrv,$destdb,...

If I run it manually like so: PS C:\sqlps> .\GetServerDetailsLight.ps1 DBSERVER LOGDB SERVER01 SERVER01 The WMI query executes just as expected. I am trying to determine why this is, or at least a useful way to trap errors from within jobs. Thanks!

• MVVM Light - master / child views and dependency properties

  - by Carl Dickinson

  I'm getting an odd problem when implementing a master / child view and custom dependency properties. Within my master view I'm binding the view model declaratively in the XAML as follows: DataContext="{Binding MainViewModelProperty, Source={StaticResource Locator}}" and my MainViewModel is exposing an observable collection which I'm binding to an ItemsControl as follows: <ItemsControl ItemsSource="{Binding Lists}" Height="490" Canvas.Top="10" Width="70"> <ItemsControl.ItemTemplate> <DataTemplate> <Canvas> <local:TaskListControl Canvas.Left="{Binding ListLeft}" Canvas.Top="{Binding ListTop}" Width="{Binding ListWidth}" Height="{Binding ListHeight}" ListDetails="{Binding}"/> </Canvas> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> TaskListControl in turn declares and bind to it's ViewModel and I've also defined a dependency property for the ListDetails property. The ListDetails property is not being set and if I remove the declarative reference to it's viewmodel the dependency property's callback does get fired. Is there a conflict with declaratively binding to viewmodels and definig dependency properties? I really like MVVM Light's blendability and want to perserve with this problem so any help would be apprectiated. If you'd like to receive the source for my project then please ask

• Makefile trickery using VPATH and include.

  - by roe

  Hi, I'm playing around with make files and the VPATH variable. Basically, I'm grabbing source files from a few different places (specified by the VPATH), and compile them into the current directory using simply a list of .o-files that I want. So far so good, now I'm generating dependency information into a file called '.depend' and including that. Gnumake will attempt to use the rules defined so far to create the included file if it doesn't exist, so that's ok. Basically, my makefile looks like this. VPATH=A/source:B/source:C/source objects=first.o second.o third.o executable: $(objects) .depend: $(objects:.o=.c) $(CC) -MM $^ > $@ include .depend Now for the real question, can I suppress the generation of the .depend file in any way? I'm currently working in a clearcase environment - sloooow, so I'd prefer to have it a bit more under control when to update the dependency information. It's more or less an academic exercise as I could just wrap the thing in a script which is touching the .depend file before executing make (thus making it more recent than any source file), but it'd interesting to know if I can somehow suppress it using 'pure' make. I cannot remove the dependency to the source files (i.e. using simply .depend:), as I'm depending on the $^ variable to do the VPATH resolution for me. If there'd be any way to only update dependencies as a result of updated #include directives, that'd be even better of course.. But I'm not holding my breath for that one.. :)

• How to implement IEquatable<T> when mutable fields are part of the equality - Problem with GetHashCo

  - by Shimmy

  Hello! I am using Entity Framework in my application. I implemented with the partial class of an entity the IEquatable<T> interface: Partial Class Address : Implements IEquatable(Of Address) 'Other part generated Public Overloads Function Equals(ByVal other As Address) As Boolean _ Implements System.IEquatable(Of Address).Equals If ReferenceEquals(Me, other) Then Return True Return AddressId = other.AddressId End Function Public Overrides Function Equals(ByVal obj As Object) As Boolean If obj Is Nothing Then Return MyBase.Equals(obj) If TypeOf obj Is Address Then Return Equals(DirectCast(obj, Address)) Else Return False End Function Public Overrides Function GetHashCode() As Integer Return AddressId.GetHashCode End Function End Class Now in my code I use it this way: Sub Main() Using e As New CompleteKitchenEntities Dim job = e.Job.FirstOrDefault Dim address As New Address() job.Addresses.Add(address) Dim contains1 = job.Addresses.Contains(address) 'True e.SaveChanges() Dim contains2 = job.Addresses.Contains(address) 'False 'The problem is that I can't remove it: Dim removed = job.Addresses.Remoeve(address) 'False End Using End Sub Note (I checked in the debugger visualizer) that the EntityCollection class stores its entities in HashSet so it has to do with the GetHashCode function, I want it to depend on the ID so entities are compared by their IDs. The problem is that when I hit save, the ID changes from 0 to its db value. So the question is how can I have an equatable object, being properly hashed. Please help me find what's wrong in the GetHashCode function (by ID) and what can I change to make it work. Thanks a lot.

• How to determine the data type of a CvMat

  - by Chris

  When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

• git clone fails with "index-pack" failed?

  - by gct

  So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

• How to compile ocaml to native code

  - by Indra Ginanjar

  i'm really interested learning ocaml, it fast (they said it could be compiled to native code) and it's functional. So i tried to code something easy like enabling mysql event scheduler. #load "unix.cma";; #directory "+mysql";; #load "mysql.cma";; let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; It work fine on ocaml interpreter, but when i was trying to compile it to native (i'm using ubuntu karmic), neither of these command worked ocamlopt -o mysqleventon mysqleventon.ml unix.cmxa mysql.cmxa ocamlopt -o mysqleventon mysqleventon.ml unix.cma mysql.cma i also tried ocamlc -c mysqleventon.ml unix.cma mysql.cma all of them resulting same message File "mysqleventon.ml", line 1, characters 0-1: Error: Syntax error Then i tried to remove the "# load", so the code goes like this let db = Mysql.quick_connect ~user:"username" ~password:"userpassword" ~database:"databasename"();; let sql = Printf.sprintf "SET GLOBAL EVENT_SCHEDULER=1;" in (Mysql.exec db sql);; The ocamlopt resulting message File "mysqleventon.ml", line 1, characters 9-28: Error: Unbound value Mysql.quick_connect I hope someone could tell me, where did i'm doing wrong.

• Issues with securing ELMAH file

  I am trying to allow the access to the elmah.axd file for only a perticular login and all others should be denied. I have followed Phil Haack's tutorial for securing the file. <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/> <add verb="POST,GET,HEAD" path="admin/elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> </httpHandlers> <location path="admin"> <system.web> <authorization> <allow users="[email protected]"/> <deny users="*"/> </authorization> </system.web> </location> First I logged in as [email protected] and tried to access the http://localhost:58961/admin/elmah.axd file and I am rightly being redirected to the Login.aspx page.

• stdexcept On Android

  - by David R.

  I'm trying to compile SoundTouch on Android. I started with this configure line: ./configure CPPFLAGS="-I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/" LDFLAGS="-Wl,-rpath-link=/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -L/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -nostdlib -lc" --host=arm-eabi --enable-shared=yes CFLAGS="-nostdlib -O3 -mandroid" host_alias=arm-eabi --no-create --no-recursion Because the Android NDK targets ARM, I also had to change the Makefile to remove the -msse2 flags to progress. When I run 'make', I get: /bin/sh ../../libtool --tag=CXX --mode=compile arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c -o FIRFilter.lo FIRFilter.cpp libtool: compile: arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c FIRFilter.cpp -o FIRFilter.o FIRFilter.cpp:46:21: error: stdexcept: No such file or directory FIRFilter.cpp: In member function 'virtual void soundtouch::FIRFilter::setCoefficients(const soundtouch::SAMPLETYPE*, uint, uint)': FIRFilter.cpp:177: error: 'runtime_error' is not a member of 'std' FIRFilter.cpp: In static member function 'static void* soundtouch::FIRFilter::operator new(size_t)': FIRFilter.cpp:225: error: 'runtime_error' is not a member of 'std' make[2]: *** [FIRFilter.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 This isn't very surprising, since the -nostdlib flag was required. Android seems to have neither stdexcept nor stdlib. How can I get past this block of compiling SoundTouch? At a guess, there may be some flag I don't know about that I should use. I could refactor the code not to use stdexcept. There may be a way to pull in the original stdexcept source and reference that. I might be able to link to a precompiled stdexcept library.

• IPhone SDK removal of NSLog causes NSArray to be undeclared !

  - by Maxwell Segal

  I have a working application I'm about to distribute and am tidying up NSLog statements in it. When I remove NSLog from from a "case" statement, the NSArray declared within the "case" statement errors as Expected expression before AND undeclared. Anybody any idea why this may be? This is happening on all case statements in my app where I'm now removing NSLog. An example code sections appears below: switch (chosenScene) { case 0: //NSLog(@"group1"); // the following NSArray errors with "expected expression.." AND "..group1Secondsarray undeclared" NSArray *group1SecondsArray = [NSArray arrayWithObjects: @"Dummy",@"1/15",@"1/30",@"1/30",@"1/60",@"1/125",@"1/250",nil]; NSArray *group1FStopArray = [NSArray arrayWithObjects: @"Dummy",@"2.8",@"2.8",@"4",@"5.6",@"5.6",@"5.6",nil]; NSString *group1SecondsText = [group1SecondsArray objectAtIndex:slider.value]; calculatedSeconds.text = group1SecondsText; NSString *group1FStopText = [group1FStopArray objectAtIndex:slider.value]; calculatedFStop.text = group1FStopText; [group1SecondsText release]; [group1FStopText release]; break;

• Updating extra attributes in a has_many, :through relationship using Rails

  - by Robbie

  I've managed to set up a many-to-many relationship between the following models Characters Skills PlayerSkills PlayerSkills, right now, has an attribute that Skills don't normally have: a level. The models look something like this (edited for conciseness): class PlayerSkill < ActiveRecord::Base belongs_to :character belongs_to :skill end class Skill < ActiveRecord::Base has_many :player_skills has_many :characters, :through => :player_skills attr_accessible :name, :description end class Character < ActiveRecord::Base belongs_to :user has_many :player_skills has_many :skills, :through => :player_skills end So nothing too fancy in the models... The controller is also very basic at this point... it's pretty much a stock update action. The form I'm looking to modify is characters#edit. Right now it renders a series of checkboxes which add/remove skills from the characters. This is great, but the whole point of using has_many :through was to track a "level" as well. Here is what I have so far: - form_for @character do |f| = f.error_messages %p = f.label :name %br = f.text_field :name %p = f.label :race %br = f.text_field :race %p = f.label :char_class %br = f.text_field :char_class %p - @skills.each do |skill| = check_box_tag "character[skill_ids][]", skill.id, @character.skills.include?(skill) =h skill.name %br %p = f.submit After it renders "skill.name", I need it to print a text_field that updates player_skill. The problem, of course, is that player_skill may or may not exist! (Depending on if the box was already ticked when you loaded the form!) From everything I've read, has_many :through is great because it allows you to treat the relationship itself as an entity... but I'm completely at a loss as to how to handle the entity in this form. As always, thanks in advance for any and all help you can give me!

• Forwarding first responder to UIScrollView unsuccessful

  - by Winston

  Hello, I am trying to create an image cropping bpx whereby the underlying image can be zoomed an scrolled while the cropping "maskview" layer stays the same and the corners can be dragged in any direction. To achieve this, the ImageView is added to a UIScrollView, and this is added to the SelectionViewController.view . I then add the cropping "maskview" layer to the SelectionViewController.view. I did this instead of adding to the scrollview so that the cropping maskview won't be expanded when the underlying image expands. @interface SelectionViewController : UIViewController <UIScrollViewDelegate> { UIImageView *photoview; // Added to self.scrollview MaskedView *maskedview; // Added to self.view UIScrollView *scrollview; // Added to self.view } The maskview has first responder status and responds accordingly. However, the only event I am interested in the maskview is if any of the corners are dragged (this works fine). The problem I want to try to solve is two-fold: If it is a pinch or zoom gesture, I am trying to forward the responder to the UIScrollview using: [self.nextResponder touchesMoved:touches withEvent:event]; The scrollview does not seem to respond. I have confirmed that the self.nextResponder after the maskedview is the SelectionViewController's view itself. From there, it doesn't seem like the UIScrollview responds. It does respond fine if I remove the cropping maskedview. If I zoom in on the underlying image and the cropping maskview rectangle is still the same, I want to now crop the actual zoomed image. Let's say for the upper left hand corner of the crop box, how can I find what the coordinates translates to in the underlying UIImageView now that the image has been zoomed? Any insight into either of these questions would be appreciated. Thank you, Winston

• CakePHP form $options['options']

  - by James

  Hey! Total CakePHP noob here. This is sort of a two fold question. In a view that is used for adding user objects I would like to use a drop down (selection) field in the form. Each user belongs to a group so when I add a user I want a drop down that contains all of the groups that the user could possibly join. Currently the group_id field is a textfield. I know how to force it to be a selection field, but I don't know how to populate the selection with the names of the groups programmatically. The Current method: echo $form->input('group_id', array( '1' => 'NameOfGroup1', '2' => 'NameOfGroup2', '3' => 'NameOfGroup3') ); I want to generate the options array programmatically though. echo $form->input('group_id', $this->Group->find('list')); This doesn't work though. I get an error: Undefined property: View::$Group [APP/views/users/add.ctp, line 8] To me this means that I don't have access to the Group object from inside my user view. How can I accomplish this? Again, I want to do it programmatically so that it updates as I add groups or remove them.

• jquery .submit live click runs more than once

  I use the following code to run my form ajax requests but when i use the live selector on a button i can see the ajax response fire 1 time, then if i re-try it 2 times, 3 times, 4 times and so on... I use .live because i also have a feature to add a post and that appears instantly so the user can remove it without refreshing the page... Then this leads to the above problem... using .click could solve this but it's not the ideal solution i'm looking for... jQuery.fn.postAjax = function(success_callback, show_confirm) { this.submit(function(e) { e.preventDefault(); if (show_confirm == true) { if (confirm('Are you sure you want to delete this item? You can\'t undo this.')) { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } } else { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } return false; }) return this; }; $(document).ready(function() { $(".delete_button").live('click', function() { $(this).parent().postAjax(function(data) { if (data.error == true) { } else { } }, true); }); });? EDIT: temporary solution is to change this.submit(function(e) { to this.unbind('submit').bind('submit',function(e) { the problem is how can i protect it for real because people who know how to use Firebug or the same tool on other browsers can easily alter my Javascript code and re-create the problem

• How to make Resig's micro-templates XHTML compliant?

  - by mshelv

  Hello, I have been experimenting with John Resig's micro-template, which works great. However, the mark-up will not pass the XHTML 1.0 Transitional validation test. (Among other things, id attributes yield errors.) Replacing tags identifiers <, with [[,]], passes validation. Thus, I created a js script which at load time (jQuery document ready) converts the square brackets back to regular markers. This works fine in FF, but not in IE, Chrome, etc. Scripts embedded within CDATA tags validate as well. Question: Is there a way to insert micro-template in a script and still pass XHTML validation? My idea was to remove the CDATA tags once the page has been loaded. But there are probably smarter ways. (Note: I'd prefer not to inject HTML via js since the mark-up will be difficult to maintain.) PS: I looked at other js templates, but they are either not XHTML compliant or too bulky. TIA for any hints.

• Problem with cruise control and visual svn

  - by Andrew

  Hi Wonder if anyone can help, I am experiencing a strange issue with my configuration of cruisecontrol.net and visual svn. I am setting the current ccnet.config <sourcecontrol type="svn"> <trunkUrl>https://bladerunner.azullo.local:8443/svn/application/trunk</trunkUrl> <executable>C:\Program Files (x86)\VisualSVN Server\bin\svn.exe</executable> <username>test</username> <password>test</password> <workingDirectory>D:\Development\Build\application\</workingDirectory> </sourcecontrol> <publishers> <xmllogger/> </publishers> <modificationDelaySeconds>10</modificationDelaySeconds> </project> When I run this I expect it to go to https://bladerunner.azullo.local:8443/svn/application/trunk, however i get the following ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'http://bladerunner.azullo.local:8080/svn/application/trunk': could not connect to server (http://bladerunner.azullo.local:8080) . Process command: C:\Program Files (x86)\VisualSVN Server\bin\svn.exe update D:\Development\build\application\ --username test --password ** --no-auth-cache --non-interactive at ThoughtWorks.CruiseControl.Core.Sourcecontrol.ProcessSourceControl.Execute(ProcessInfo processInfo) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Svn.UpdateSource(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) So for some reason it goes to 'http://bladerunner.azullo.local:8080/svn/application/trunk' If I remove the username and password elements in the ccnet.config. It goes to the correct url. I dont understand this behaviour. I have configured visual svn with a certificate using Active directory Certificate Services, if this was the problem I would expect it to show an error regarding the certificate instead of changing the url. I have cleared our state etc Any Ideas

• How to count term frequency for set of documents?

  - by ManBugra

  i have a Lucene-Index with following documents: doc1 := { caldari, jita, shield, planet } doc2 := { gallente, dodixie, armor, planet } doc3 := { amarr, laser, armor, planet } doc4 := { minmatar, rens, space } doc5 := { jove, space, secret, planet } so these 5 documents use 14 different terms: [ caldari, jita, shield, planet, gallente, dodixie, armor, amarr, laser, minmatar, rens, jove, space, secret ] the frequency of each term: [ 1, 1, 1, 4, 1, 1, 2, 1, 1, 1, 1, 1, 2, 1 ] for easy reading: [ caldari:1, jita:1, shield:1, planet:4, gallente:1, dodixie:1, armor:2, amarr:1, laser:1, minmatar:1, rens:1, jove:1, space:2, secret:1 ] What i do want to know now is, how to obtain the term frequency vector for a set of documents? for example: Set<Documents> docs := [ doc2, doc3 ] termFrequencies = magicFunction(docs); System.out.pring( termFrequencies ); would result in the ouput: [ caldari:0, jita:0, shield:0, planet:2, gallente:1, dodixie:1, armor:2, amarr:1, laser:1, minmatar:0, rens:0, jove:0, space:0, secret:0 ] remove all zeros: [ planet:2, gallente:1, dodixie:1, armor:2, amarr:1, laser:1 ] Notice, that the result vetor contains only the term frequencies of the set of documents. NOT the overall frequencies of the whole index! The term 'planet' is present 4 times in the whole index but the source set of documents only contains it 2 times. A naive implementation would be to just iterate over all documents in the docs set, create a map and count each term. But i need a solution that would also work with a document set size of 100.000 or 500.000. Is there a feature in Lucene i can use to obtain this term vector? If there is no such feature, how would a data structure look like someone can create at index time to obtain such a term vector easily and fast? I'm not that Lucene expert so i'am sorry if the solution is obvious or trivial.

• csc.exe not found error

  - by pokrate

  I have installed a fresh copy of windows xp 2002 with SP2, and then VS.net 2008 enterprise edition. I am trying to build a simplest possible web application, and its not compiling giving error csc.exe not found. I googled a lot, and spot the problem in the following section in web.config : <system.codedom> <compilers> <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="WarnAsError" value="false"/> </compiler> <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="OptionInfer" value="true"/> <providerOption name="WarnAsError" value="false"/> </compiler> </compilers> </system.codedom> But if i remove the csharp compiler section , and then compile, it compiles fine with vb compiler section. And if I change the value from v3.5 to v2.0 in the of csharp section, then also it compiles fine. But then all my Linq Queries are not recognized by the compiler. But System.Linq and all classes present in it are accessible in the code. Please help in this weird behavior.
