• Safari/Chrome problem with ajaxsubmit?

  - by Jan

  Hi I'm currently having some weird issues with ajaxsubmit (http://jquery.malsup.com/form/#ajaxSubmit), which I'm currently using in a project. I have a flow where I need to open a form into a modal window. I'm using fancybox for that and it works like a charm. When the form has been forced to open in the fancybox window there can happen two things. 1) If the user who is about to submit the form is logged in she should see a confirmation in the modal box, that her input was succesfully submitted 2)If the user is not logged in there should be loaded a login form once she hits the submit button 2.1) When the user has logged in she should receive a confirmation in the modal box. This is also working like a charm in Firefox, IE8 and IE7 but not in Safari or Chrome. The weird part is that it seems like safari and chrome are completely ignoring my ajaxsubmit form. To force the first form to be opened I use the follwoing script - this part is working in both Safari and Chrome. $(".klikEnPrisForm").ajaxForm({ success: function(data){ $.fancybox({'content':data}); } }); My ajaxsubmit form scrip looks like this var options = { url: '/?altTemplate=XmlProxyKlikEnPris', dataType: 'xml', data: $(this).serializeArray(), success: function(data) { if ($(data).find('loggetind').text() == 'true') { $("#klikenpris").hide(); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/KlikEnPrisAccept?tilKvittering=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } else { $("#klikenpris").hide(); $("#fancybox-wrap").css({ 'width': '480px', 'height': '220px' }); $("#fancybox-inner").css({ 'width': '460px', 'height': '220px' }); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/login.aspx?loginklikpris=0&klikpris=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } } }; // bind to the form's submit event $('#klikenprisform').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); I have tried inserting an alert in the succes callback function but it's never being called it seems. It seems like the default action is not being overruled by the link written in the "url" in ajaxsubmit. I'm really puzzled about this, since it's working nicely in other browsers and I'm completely lost on how I should approach the debugging in safari/chrome. I hope all the above makes sense and I'm looking forward to hear any suggestions. Cheers!

• itertools.product eliminating repeated reversed tuples

  - by genclik27

  I asked a question yesterday and thanks to Tim Peters, it is solved. The question is here; itertools.product eliminating repeated elements The new question is further version of this. This time I will generate tuples inside of tuples. Here is an example; lis = [[(1,2), (3,4)], [(5,2), (1,2)], [(2,1), (1,2)]] When I use it in itertools.product function this is what I get, ((1, 2), (5, 2), (2, 1)) ((1, 2), (5, 2), (1, 2)) ((1, 2), (1, 2), (2, 1)) ((1, 2), (1, 2), (1, 2)) ((3, 4), (5, 2), (2, 1)) ((3, 4), (5, 2), (1, 2)) ((3, 4), (1, 2), (2, 1)) ((3, 4), (1, 2), (1, 2)) I want to change it in a way that if a sequence has (a,b) inside of it, then it can not have (b,a). In this example if you look at this sequence ((3, 4), (1, 2), (2, 1)) it has (1,2) and (2,1) inside of it. So, this sequence ((3, 4), (1, 2), (2, 1)) should not be considered in the results. As I said, I asked similar question before, in that case it was not considering duplicate elements. I try to adapt it to my problem. Here is modified code. Changed parts in old version are taken in comments. def reverse_seq(seq): s = [] for i in range(len(seq)): s.append(seq[-i-1]) return tuple(s) def uprod(*seqs): def inner(i): if i == n: yield tuple(result) return for elt in sets[i] - reverse: #seen.add(elt) rvrs = reverse_seq(elt) reverse.add(rvrs) result[i] = elt for t in inner(i+1): yield t #seen.remove(elt) reverse.remove(rvrs) sets = [set(seq) for seq in seqs] n = len(sets) #seen = set() reverse = set() result = [None] * n for t in inner(0): yield t In my opinion this code should work but I am getting error for the input lis = [[(1,2), (3,4)], [(5,2), (1,2)], [(2,1), (1,2)]]. I could not understand where I am wrong. for i in uprod(*lis): print i Output is, ((1, 2), (1, 2), (1, 2)) Traceback (most recent call last): File "D:\Users\SUUSER\workspace tree\sequence_covering _array\denemeler_buraya.py", line 39, in <module> for i in uprod(*lis): File "D:\Users\SUUSER\workspace tree\sequence_covering _array\denemeler_buraya.py", line 32, in uprod for t in inner(0): File "D:\Users\SUUSER\workspace tree\sequence_covering _array\denemeler_buraya.py", line 22, in inner for t in inner(i+1): File "D:\Users\SUUSER\workspace tree\sequence_covering _array\denemeler_buraya.py", line 25, in inner reverse.remove(rvrs) KeyError: (2, 1) Thanks,

• MySQL query, 2 similar servers, 2 minute difference in execution times

  - by mr12086

  I had a similar question on stack overflow, but it seems to be more server/mysql setup related than coding. The queries below all execute instantly on our development server where as they can take upto 2 minutes 20 seconds. The query execution time seems to be affected by home ambiguous the LIKE string's are. If they closely match a country that has few matches it will take less time, and if you use something like 'ge' for germany - it will take longer to execute. But this doesn't always work out like that, at times its quite erratic. Sending data appears to be the culprit but why and what does that mean. Also memory on production looks to be quite low (free memory)?

  Which registry keys need to be edited to change the default browser? I have found these keys so far and they seem to do what I want, but I am not sure if I have found all of them: Data in: HKEY_CURRENT_USER\Software\Classes\http\shell\open\command HKEY_CURRENT_USER\Software\Classes\https\shell\open\command HKEY_CURRENT_USER\Software\Classes\ftp\shell\open\command Value in: HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\MuiCache Are there any other keys which would need to be changed, so that it is done perfectly?

• Feedback on iterating over type-safe enums

  - by Sumant

  In response to the earlier SO question "Enumerate over an enum in C++", I came up with the following reusable solution that uses type-safe enum idiom. I'm just curious to see the community feedback on my solution. This solution makes use of a static array, which is populated using type-safe enum objects before first use. Iteration over enums is then simply reduced to iteration over the array. I'm aware of the fact that this solution won't work if the enumerators are not strictly increasing. template<typename def, typename inner = typename def::type> class safe_enum : public def { typedef typename def::type type; inner val; static safe_enum array[def::end - def::begin]; static bool init; static void initialize() { if(!init) // use double checked locking in case of multi-threading. { unsigned int size = def::end - def::begin; for(unsigned int i = 0, j = def::begin; i < size; ++i, ++j) array[i] = static_cast<typename def::type>(j); init = true; } } public: safe_enum(type v = def::begin) : val(v) {} inner underlying() const { return val; } static safe_enum * begin() { initialize(); return array; } static safe_enum * end() { initialize(); return array + (def::end - def::begin); } bool operator == (const safe_enum & s) const { return this->val == s.val; } bool operator != (const safe_enum & s) const { return this->val != s.val; } bool operator < (const safe_enum & s) const { return this->val < s.val; } bool operator <= (const safe_enum & s) const { return this->val <= s.val; } bool operator > (const safe_enum & s) const { return this->val > s.val; } bool operator >= (const safe_enum & s) const { return this->val >= s.val; } }; template <typename def, typename inner> safe_enum<def, inner> safe_enum<def, inner>::array[def::end - def::begin]; template <typename def, typename inner> bool safe_enum<def, inner>::init = false; struct color_def { enum type { begin, red = begin, green, blue, end }; }; typedef safe_enum<color_def> color; template <class Enum> void f(Enum e) { std::cout << static_cast<unsigned>(e.underlying()) << std::endl; } int main() { std::for_each(color::begin(), color::end(), &f<color>); color c = color::red; }

• Configuring Fed Authentication Methods in OIF / IdP

  - by Damien Carru

  In this article, I will provide examples on how to configure OIF/IdP to map OAM Authentication Schemes to Federation Authentication Methods, based on the concepts introduced in my previous entry. I will show examples for the three protocols supported by OIF: SAML 2.0 SSO SAML 1.1 SSO OpenID 2.0 Enjoy the reading! Configuration As I mentioned in my previous article, mapping Federation Authentication Methods to OAM Authentication Schemes is protocol dependent, since the methods are defined in the various protocols (SAML 2.0, SAML 1.1, OpenID 2.0). As such, the WLST commands to set those mappings will involve: Either the SP Partner Profile and affect all Partners referencing that profile, which do not override the Federation Authentication Method to OAM Authentication Scheme mappings Or the SP Partner entry, which will only affect the SP Partner It is important to note that if an SP Partner is configured to define one or more Federation Authentication Method to OAM Authentication Scheme mappings, then all the mappings defined in the SP Partner Profile will be ignored. WLST Commands The two OIF WLST commands that can be used to define mapping Federation Authentication Methods to OAM Authentication Schemes are: addSPPartnerProfileAuthnMethod() to define a mapping on an SP Partner Profile, taking as parameters: The name of the SP Partner Profile The Federation Authentication Method The OAM Authentication Scheme name addSPPartnerAuthnMethod() to define a mapping on an SP Partner , taking as parameters: The name of the SP Partner The Federation Authentication Method The OAM Authentication Scheme name Note: I will discuss in a subsequent article the other parameters of those commands. In the next sections, I will show examples on how to use those methods: For SAML 2.0, I will configure the SP Partner Profile, that will apply all the mappings to SP Partners referencing this profile, unless they override mapping definition For SAML 1.1, I will configure the SP Partner. For OpenID 2.0, I will configure the SP/RP Partner SAML 2.0 Test Setup In this setup, OIF is acting as an IdP and is integrated with a remote SAML 2.0 SP partner identified by AcmeSP. In this test, I will perform Federation SSO with OIF/IdP configured to: Use LDAPScheme as the Authentication Scheme Use BasicScheme as the Authentication Scheme Map BasicSessionScheme  to  the urn:oasis:names:tc:SAML:2.0:ac:classes:Password Federation Authentication Method Use OAMLDAPPluginAuthnScheme as the Authentication Scheme Map OAMLDAPPluginAuthnScheme to  the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport Federation Authentication Method LDAPScheme as Authentication Scheme Using the OOTB settings regarding user authentication in OAM, the user will be challenged via a FORM based login page based on the LDAPScheme. Also the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme. After authentication via FORM, OIF/IdP would issue an Assertion similar to: <samlp:Response ...>    <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>    <samlp:Status>        <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>    </samlp:Status>    <saml:Assertion ...>        <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>        <dsig:Signature>            ...        </dsig:Signature>        <saml:Subject>            <saml:NameID ...>[email protected]</saml:NameID>            <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">                <saml:SubjectConfirmationData .../>            </saml:SubjectConfirmation>        </saml:Subject>        <saml:Conditions ...>            <saml:AudienceRestriction>                <saml:Audience>https://acme.com/sp</saml:Audience>            </saml:AudienceRestriction>        </saml:Conditions>        <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z">            <saml:AuthnContext>                <saml:AuthnContextClassRef>                   urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport                </saml:AuthnContextClassRef>            </saml:AuthnContext>        </saml:AuthnStatement>    </saml:Assertion></samlp:Response> BasicScheme as Authentication Scheme For this test, I will switch the default Authentication Scheme for the SP Partner Profile to BasicScheme instead of LDAPScheme. I will use the OIF WLST setSPPartnerProfileDefaultScheme() command and specify which scheme to be used as the default for the SP Partner Profile referenced by AcmeSP (which is saml20-sp-partner-profile in this case: getFedPartnerProfile("AcmeSP", "sp") ): Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the setSPPartnerProfileDefaultScheme() command:setSPPartnerProfileDefaultScheme("saml20-sp-partner-profile", "BasicScheme") Exit the WLST environment:exit() The user will now be challenged via HTTP Basic Authentication defined in the BasicScheme for AcmeSP. Also, as noted earlier, the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme.

No Federation Authentication Method is defined OOTB for OpenID 2.0, so if the IdP/OP issue an SSO response with a PAPE Response element, it will specify the scheme name instead of Federation Authentication Methods After authentication via FORM, OIF/IdP would issue an SSO Response similar to: https://acme.com/openid?refid=id-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.mode=id_res&openid.op_endpoint=https%3A%2F%2Fidp.com%2Fopenid&openid.claimed_id=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.identity=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.return_to=https%3A%2F%2Facme.com%2Fopenid%3Frefid%3Did-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.response_nonce=2014-03-24T19%3A20%3A06Zid-YPa2kTNNFftZkgBb460jxJGblk2g--iNwPpDI7M1&openid.assoc_handle=id-6a5S6zhAKaRwQNUnjTKROREdAGSjWodG1el4xyz3&openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&openid.ax.mode=fetch_response&openid.ax.type.attr0=http%3A%2F%2Fsession%2Fcount&openid.ax.value.attr0=1&openid.ax.type.attr1=http%3A%2F%2Fopenid.net%2Fschema%2FnamePerson%2Ffriendly&openid.ax.value.attr1=My+name+is+Bobby+Smith&openid.ax.type.attr2=http%3A%2F%2Fschemas.openid.net%2Fax%2Fapi%2Fuser_id&openid.ax.value.attr2=bob&openid.ax.type.attr3=http%3A%2F%2Faxschema.org%2Fcontact%2Femail&openid.ax.value.attr3=bob%40oracle.com&openid.ax.type.attr4=http%3A%2F%2Fsession%2Fipaddress&openid.ax.value.attr4=10.145.120.253&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.auth_time=2014-03-24T19%3A20%3A05Z&openid.pape.auth_policies=LDAPScheme&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to%2Cresponse_nonce%2Cassoc_handle%2Cns.ax%2Cax.mode%2Cax.type.attr0%2Cax.value.attr0%2Cax.type.attr1%2Cax.value.attr1%2Cax.type.attr2%2Cax.value.attr2%2Cax.type.attr3%2Cax.value.attr3%2Cax.type.attr4%2Cax.value.attr4%2Cns.pape%2Cpape.auth_time%2Cpape.auth_policies&openid.sig=mYMgbGYSs22l8e%2FDom9NRPw15u8%3D Mapping LDAPScheme To map the LDAP Scheme to the http://schemas.openid.net/pape/policies/2007/06/phishing-resistant and http://openid-policies/password-protected policies Federation Authentication Methods, I will execute the addSPPartnerAuthnMethod() method (the policies will be comma separated): Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the addSPPartnerAuthnMethod() command:addSPPartnerAuthnMethod("AcmeRP", "http://schemas.openid.net/pape/policies/2007/06/phishing-resistant,http://openid-policies/password-protected", "LDAPScheme") Exit the WLST environment:exit() After authentication via FORM, OIF/IdP would now issue an Assertion similar to (see that the method was changed from LDAPScheme to the two policies): https://acme.com/openid?refid=id-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.mode=id_res&openid.op_endpoint=https%3A%2F%2Fidp.com%2Fopenid&openid.claimed_id=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.identity=https%3A%2F%2Fidp.com%2Fopenid%3Fid%3Did-38iCmmlAVEXPsFjnFVKArfn5RIiF75D5doorhEgqqPM%3D&openid.return_to=https%3A%2F%2Facme.com%2Fopenid%3Frefid%3Did-9PKVXZmRxAeDYcgLqPm36ClzOMA-&openid.response_nonce=2014-03-24T19%3A20%3A06Zid-YPa2kTNNFftZkgBb460jxJGblk2g--iNwPpDI7M1&openid.assoc_handle=id-6a5S6zhAKaRwQNUnjTKROREdAGSjWodG1el4xyz3&openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&openid.ax.mode=fetch_response&openid.ax.type.attr0=http%3A%2F%2Fsession%2Fcount&openid.ax.value.attr0=1&openid.ax.type.attr1=http%3A%2F%2Fopenid.net%2Fschema%2FnamePerson%2Ffriendly&openid.ax.value.attr1=My+name+is+Bobby+Smith&openid.ax.type.attr2=http%3A%2F%2Fschemas.openid.net%2Fax%2Fapi%2Fuser_id&openid.ax.value.attr2=bob&openid.ax.type.attr3=http%3A%2F%2Faxschema.org%2Fcontact%2Femail&openid.ax.value.attr3=bob%40oracle.com&openid.ax.type.attr4=http%3A%2F%2Fsession%2Fipaddress&openid.ax.value.attr4=10.145.120.253&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.auth_time=2014-03-24T19%3A20%3A05Z&openid.pape.auth_policies=http%3A%2F%2Fschemas.openid.net%2Fpape%2Fpolicies%2F2007%2F06%2Fphishing-resistant+http%3A%2F%2Fopenid-policies%2Fpassword-protected&openid.signed=op_endpoint%2Cclaimed_id%2Cidentity%2Creturn_to%2Cresponse_nonce%2Cassoc_handle%2Cns.ax%2Cax.mode%2Cax.type.attr0%2Cax.value.attr0%2Cax.type.attr1%2Cax.value.attr1%2Cax.type.attr2%2Cax.value.attr2%2Cax.type.attr3%2Cax.value.attr3%2Cax.type.attr4%2Cax.value.attr4%2Cns.pape%2Cpape.auth_time%2Cpape.auth_policies&openid.sig=mYMgbGYSs22l8e%2FDom9NRPw15u8%3D In the next article, I will cover how OIF/IdP can be configured so that an SP can request a specific Federation Authentication Method to challenge the user during Federation SSO.Cheers,Damien Carru

• SQL SERVER – 2008 – Unused Index Script – Download

  - by pinaldave

  Download Missing Index Script with Unused Index Script Performance Tuning is quite interesting and Index plays a vital role in it. A proper index can improve the performance and a bad index can hamper the performance. Here is the script from my script bank which I use to identify unused indexes on any database. Please note, if you should not drop all the unused indexes this script suggest. This is just for guidance. You should not create more than 5-10 indexes per table. Additionally, this script sometime does not give accurate information so use your common sense. Any way, the scripts is good starting point. You should pay attention to User Scan, User Lookup and User Update when you are going to drop index. The generic understanding is if this values are all high and User Seek is low, the index needs tuning. The index drop script is also provided in the last column.

• How to manage memory using classes in Objective-C?

  - by Flipper

  This is my first time creating an iPhone App and I am having difficulty with the memory management because I have never had to deal with it before. I have a UITableViewController and it all works fine until I try to scroll down in the simulator. It crashes saying that it cannot allocate that much memory. I have narrowed it down to where the crash is occurring: - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // Dequeue or create a cell UITableViewCellStyle style = UITableViewCellStyleDefault; UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:@"BaseCell"]; if (!cell) cell = [[[UITableViewCell alloc] initWithStyle:style reuseIdentifier:@"BaseCell"] autorelease]; NSString* crayon; // Retrieve the crayon and its color if (aTableView == self.tableView) { crayon = [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row] getName]; } else { crayon = [FILTEREDKEYS objectAtIndex:indexPath.row]; } cell.textLabel.text = crayon; if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor]; return cell; } Here is the getName method: - (NSString*)getName { return name; } name is defined as: @property (nonatomic, retain) NSString *name; Now sectionArray is an NSMutableArray with instances of a class that I created Term in it. Term has a method getName that returns a NSString*. The problem seems to be the part of where crayon is being set and getName is being called. I have tried adding autorelease, release, and other stuff like that but that just causes the entire app to crash before even launching. Also if I do: cell.textLabel.text = @"test"; //crayon; /*if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor];*/ Then I get no error whatsoever and it all scrolls just fine. Thanks in advance for the help! Edit: Here is the full Log of when I try to run the app and the error it gives when it crashes: [Session started at 2010-12-29 04:23:38 -0500.] [Session started at 2010-12-29 04:23:44 -0500.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

• Java. Outside classes accessing protected methods.

  - by Jake

  Suppose I have a class in my package org.jake and it has a method with default access (no modifier). Then the method is visible inside the package only. However, when someone receives the jar of my framework, what is to stop them from writing a new class, declaring its package as org.jake, and using my supposedly invisible method? In other words, is there anything I can do to prevent them from doing that?

• Can I have conditional construction of classes when using IoC.Resolve ?

  - by Corpsekicker

  I have a service class which has overloaded constructors. One constructor has 5 parameters and the other has 4. Before I call, var service = IoC.Resolve<IService>(); I want to do a test and based on the result of this test, resolve service using a specific constructor. In other words, bool testPassed = CheckCertainConditions(); if (testPassed) { //Resolve service using 5 paramater constructor } else { //Resolve service using 4 parameter constructor //If I use 5 parameter constructor under these conditions I will have epic fail. } Is there a way I can specify which one I want to use?

• jquery slide toggle divs without creating multiple classes, functions, etc... ui accordion

  - by SPE

  Greetings, based on the jquery ui accordion I'm using, I have added a slide toggle to my accordion list items. so what happens is I click on an li and a div slides down underneath to reveal more content. The issue I'm having is that I find myself having to create multiple id's to reference the slidetoggle. example of the div id css: #panel, #panel2, #panel3, #panel4, etc.... the Is there a way I can use the slide toggle without having to adding another number so it will slide? I have 50 list items I'm using: Here's a sample of the js (as you can see where I'm going with this): $(".btn-slide").click(function(){ $("#panel").slideToggle("slow"); $(this).toggleClass("active"); return false; }); $(".btn-slide2").click(function(){ $("#panel2").slideToggle("slow"); $(this).toggleClass("active"); return false; }); sample html: <li><div class="slide"><a href="#" class="btn-slide">One</a></div><div id="panel"></div></li> <li><div class="slide"><a href="#" class="btn-slide2">Two</a></div><div id="panel2"></div></li>

  If I have a List in a Grails domain class, is there a way to override the addX() and removeX() accessors to it? In the following example, I'd expect MyObject.addThing(String) to be called twice. In fact, the output is: Adding thing: thing 2 class MyObject { static hasMany = [things: String] List things = [] void addThing(String newThing) { println "Adding thing: ${newThing}" things << newThing } } class BootStrap { def init = { servletContext -> MyObject o = new MyObject().save() o.things << 'thing 1' o.addThing('thing 2') } def destroy = { } }

• JSF in jetty-equinox, Cannot find Bean classes in other bundles!

  - by Arnold

  Hi I have problems running JSF in an OSGi environment. I am using jetty web container and equinox to provide the OSGi functionality. The structure of my application is as follows: The first bundle has all the JSF libs, web.xml and a config.xml. It looks as the following: bundle1 ----src/main/java -------de/package ----------Activator.java ----------JSFResolver.java ----src/main/resource ------ WebContent ----------META-INF -------------face-config.xml --------------web.xhtml ----------start.xhtml -----------include.xhtml ----libs (containing all JSF required Jars) The structure of the second bundle is as follows: bundle2 ---src/main/java ------de/package ----------Bean.java ---src/main/resource ------META-INF ---------face-config.xml ------WebContent ---------index.xhtml When running the application of equinox, the bundle1 is the main bundle where all the browser requests are sent to. In the second bundle, the 'index.xhtml' file can be retrieved the by first bundle upon request. The 'index.xhtml' in bundle 2 gets its values and properties from the 'Bean.java' in bundle 2. The problem comes when i request the 'index.xhtml', the Bean.java class is not found. I think this is because the class loader of bundle1 cannot find it, it has no knowledge of it. So i would like to ask if anyone knows how to solve this problem. If so please do assist me, i have tried all the possibilities i had.. Is it infact possible to have JSF run on multiple bundles using the same FaceletsContex? Can i be able to have seperate faces-config.xml files in each bundle, which can all be connected other faces-config.xml in other bundles? Can anyone please provide me a solution. Sample code would help. thanks workspace_current.rar Arnold

• Why don't all System.Web.UI.WebControl classes with Text properties implement ITextControl?

  - by jrummell

  I'm curious why only some System.Web.UI.WebControl controls implement certain interfaces when they have the same properties of an interface. For instance, there are plenty of controls that have a Text property but only the following implement ITextControl: Label Literal DataBoundLiteral TextBox ListControl (TextBox and ListControl actually implement IEditableTextControl which implements ITextControl) TableCell, Button, HyperLink and others don't so I have to write code like this ITextControl textControl = control as ITextControl; TableCell tableCell = control as TableCell; if (textControl != null) { textControl.Text = value; } else if (tableCell != null) { tableCell.Text = value; } instead of this control.Text = value; Was this a design decision or an oversight?

• Why aren't APT generated classes being compiled by Eclipse?

  - by yamsha

  In my Eclipse project I'm using a third-party annotation processor, Hibernate Metamodel Generator to be exact. The annotation processor works as expected and generates files as specified by the spec. These files are generated inside the directory of the Eclipse project under a "gen" folder. In the project properties this is correctly reflected since two source folders exist - "src" and "gen." However, when the project is built for some reason all the [generated] sources under "gen" are not compiled (checking the "bin" directory I only see .class file from the "src" directory). Does anyone know why this is happening?

• What is the best way to attach static methods to classes rather than to instances of a class?

  If I have a method for calculating the greatest common divisor of two integers as: public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } What would be the best way to attach that to the System.Math class? Here are the three ways I have come up with: public static int GCD(this int a, int b) { return b == 0 ? a : b.GCD(a % b); } // Lame... var gcd = a.GCD(b); and: public static class RationalMath { public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } } // Lame... var gcd = RationalMath.GCD(a, b); and: public static int GCD(this Type math, int a, int b) { return b == 0 ? a : typeof(Math).GCD(b, a % b); } // Neat? var gcd = typeof(Math).GCD(a, b); The desired syntax is Math.GCD since that is the standard for all mathematical functions. Any suggestions? What should I do to get the desired syntax?

• include_once error : failed to open stream in Boonex Dolphin v7.0.9

  - by Guillaume Pierre

  first let me say I'm a beginner in PHP, specifically PHP Object-oriented programming. I'm working on a V7.0.9 dolphin version.http://www.boonex.com/dolphin While I'm trying to include a class.php from a 3rd-part developer I work with <?php include_once ('modules/developer/configure/classes/class.php'); I get this error : Warning: include_once(modules/developer/configure/classes/ClassExample.php): failed to open stream: No such file or directory in /var/www/vhosts/mysite.com/httpdocs/dolphin/inc/classes/BxDolPageView.php(612) : eval()'d code on line 2 Warning: include_once(): Failed opening 'modules/developer/configure/classes/ClassExample.php' for inclusion (include_path='.:') in /var/www/vhosts/mysite.com/httpdocs/dolphin/inc/classes/BxDolPageView.php(612) : eval()'d code on line 2 Fatal error: Class 'ClassExample' not found in /var/www/vhosts/mysite.com/httpdocs/dolphin/inc/classes/BxDolPageView.php(612) : eval()'d code on line 6 I'm trying to figure out where is the problem... does it comes from Boonex? or is it linked to my server configuration? I really don't know where to begin to resolve... Thx in advance for your kind help if you get knowledge on it

• Is it possible to create static classes in PHP (like in C#)?

  - by aleemb

  I want to create a static class in PHP and have it behave like it does in C#, so Constructor is automatically called on the first call to the class No instantiation required Something of this sort... static class Hello { private static $greeting = 'Hello'; private __construct() { $greeting .= ' There!'; } public static greet(){ echo $greeting; } } Hello::greet(); // Hello There!

• Why does this Grails/HQL query with a JOIN return Lists of pairs of domain classes?

  - by ?????

  I'm having trouble figuring out how to do a "join" in Groovy/Grails and the return values I get person = User.get(user.id) def latestPhotosForUser = PhotoOwner.findAll("FROM PhotoOwner AS a, PhotoStorage AS b WHERE (a.owner=:person AND a.photo = b)", [person:person], [max:3]) latestPhotosForUser isn't a list of PhotoOwners. It's a list of [PhotoOwner, PhotoStorage] pairs. Since I'm doing a PhotoOwner.findAll, I would have expected to see only PhotoOwners. Am I doing something wrong, or is this the proper behavior?

• Singleton class design in C#, are these two classes equivalent?

  - by Oskar

  I was reading up on singleton class design in C# on this great resource and decided to go with alternative 4: public sealed class Singleton1 { static readonly Singleton1 _instance = new Singleton1(); static Singleton1() { } Singleton1() { } public static Singleton1 Instance { get { return _instance; } } } Now I wonder if this can be rewritten using auto properties like this? public sealed class Singleton2 { static Singleton2() { Instance = new Singleton2(); } Singleton2() { } public static Singleton2 Instance { get; private set; } } If its only a matter of readability I definitely prefer the second version, but I want to get it right.

• Whats the scope of c code within objective-c classes?

  - by roja

  I was reading up about bypassing objective-c's messaging to gain performance (irrelevant to this specific question) when i found an interesting bit of code: #import <Cocoa/Cocoa.h> @interface Fib : NSObject { } - (long long) cFib: (NSUInteger) number; @end @implementation Fib // c implementation of fib long long cFibIMP(NSUInteger number) { return (number < 3) ? 1 : cFib(number - 1) + cFib(number - 2); } // method wrapper for c implementation of fib - (long long) cFib: (NSUInteger) number { return cFibIMP(number); } @end My question is; when using c function, within an objective-c object, what scope is the c function (cFibIMP in this particular case) placed in? Does the objective-c class encapsulate the c function removing change of name-clash or is the c function simply dumped into the global scope of the whole objective-c program?
