  • Innodb setting in xampp doesn't seem locate my.cnf file....

    - by bala3569
    I created a new mysql database and i want to use foreign keys with it... I googled and found out this... InnoDB is one of MySQL storage engines, it supports transactions, row-level locking, and foreign-keys. However, by default, InnoDB is not enabled by XAMPP. To enable it, locate the my.cnf configuration file (normally in C:/xampp/mysql/bin directory) and search for the following lines: # Comment the following if you are using InnoDB tables But the path C:/xampp/mysql/bin directory in my system doesn't seem to have such a file... Look at this image http://img691.imageshack.us/img691/524/mysqln.jpg Where is my.cnf file? Any suggestion...

  • Python hashable dicts

    - by TokenMacGuy
    As an exercise, and mostly for my own amusement, I'm implementing a backtracking packrat parser. The inspiration for this is i'd like to have a better idea about how hygenic macros would work in an algol-like language (as apposed to the syntax free lisp dialects you normally find them in). Because of this, different passes through the input might see different grammars, so cached parse results are invalid, unless I also store the current version of the grammar along with the cached parse results. (EDIT: a consequence of this use of key-value collections is that they should be immutable, but I don't intend to expose the interface to allow them to be changed, so either mutable or immutable collections are fine) The problem is that python dicts cannot appear as keys to other dicts. Even using a tuple (as I'd be doing anyways) doesn't help. >>> cache = {} >>> rule = {"foo":"bar"} >>> cache[(rule, "baz")] = "quux" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unhashable type: 'dict' >>> I guess it has to be tuples all the way down. Now the python standard library provides approximately what i'd need, collections.namedtuple has a very different syntax, but can be used as a key. continuing from above session: >>> from collections import namedtuple >>> Rule = namedtuple("Rule",rule.keys()) >>> cache[(Rule(**rule), "baz")] = "quux" >>> cache {(Rule(foo='bar'), 'baz'): 'quux'} Ok. But I have to make a class for each possible combination of keys in the rule I would want to use, which isn't so bad, because each parse rule knows exactly what parameters it uses, so that class can be defined at the same time as the function that parses the rule. But combining the rules together is much more dynamic. In particular, I'd like a simple way to have rules override other rules, but collections.namedtuple has no analogue to dict.update(). Edit: An additional problem with namedtuples is that they are strictly positional. Two tuples that look like they should be different can in fact be the same: >>> you = namedtuple("foo",["bar","baz"]) >>> me = namedtuple("foo",["bar","quux"]) >>> you(bar=1,baz=2) == me(bar=1,quux=2) True >>> bob = namedtuple("foo",["baz","bar"]) >>> you(bar=1,baz=2) == bob(bar=1,baz=2) False tl'dr: How do I get dicts that can be used as keys to other dicts? Having hacked a bit on the answers, here's the more complete solution I'm using. Note that this does a bit extra work to make the resulting dicts vaguely immutable for practical purposes. Of course it's still quite easy to hack around it by calling dict.__setitem__(instance, key, value) but we're all adults here. class hashdict(dict): """ hashable dict implementation, suitable for use as a key into other dicts. >>> h1 = hashdict({"apples": 1, "bananas":2}) >>> h2 = hashdict({"bananas": 3, "mangoes": 5}) >>> h1+h2 hashdict(apples=1, bananas=3, mangoes=5) >>> d1 = {} >>> d1[h1] = "salad" >>> d1[h1] 'salad' >>> d1[h2] Traceback (most recent call last): ...

  • How is the iPhone SMS compose view implemented?

    - by erotsppa
    Regarding the SMS compose view as show in the picture below: I have two questions: 1) How is the text entry box implemented? There are no standard control from the API and the box is smart enough to resize when you press enter OR when the text is too long. Also the bar resizes with it. How is this done with the least coding? 2) How to code it such that when the keyboard shows up the whole view shifts up? Typically when the keyboard shows, it goes over your current view.

  • How to change which item is “outlined” in a ListBox without changing the selection?

    - by Timwi
    How do you change which item is “outlined” in a ListBox? See the following screenshot for clarification: Background: I want to have a standard multi-select listbox that works normally. Unfortunately, the Windows Forms ListBox (with SelectionMode.MultiExtended) is not fully functional. The missing functionality is that it doesn’t let you select a disjoint set of items by using Ctrl+Arrow keys and Ctrl+Space. (Try it in Windows Explorer to see how it’s supposed to work.) I am trying to subclass ListBox and add this missing functionality. To this end, I intend to respond to Ctrl+Arrow keys in the OnKeyDown protected method, but in order to do so, I need to be able to move the outline without changing the set of selected items. How do I do that?

  • Problem in populating a dictionary using Enumerable.Range()

    - by Newbie
    If I do for (int i = 0; i < appSettings.Count; i++) { string key = appSettings.Keys[i]; euFileDictionary.Add(key, appSettings[i]); } It is working fine. When I am trying the same thing using Enumerable.Range(0, appSettings.Count).Select(i => { string Key = appSettings.Keys[i]; string Value = appSettings[i]; euFileDictionary.Add(Key, Value); }).ToDictionary<string,string>(); I am getting a compile time error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Any idea? Using C#3.0 Thanks

  • Ruby on Rails Foreigner plugin not working for SQL Server

    - by Earlz
    Well, now that I've finally got my stupid ODBC stuff configured, I took a schema.rb file that I dumped from a Postgres database and did a db:schema:load on it in a Rails project configured for SQL Server. Well, it sets up all the schema in the SQL Server database except for a minor detail: No foreign keys are created. The rake command doesn't show any errors and does say it is adding foreign keys. But they don't actually get added. This is the last bit from the command: -- add_foreign_key("workhistoryform", "form", {:name=>"workhistoryform_form_rid_fkey", :column=>"form_rid", :primary_key=>"form_rid"}) -> 0.0002s -- initialize_schema_migrations_table() -> 0.0092s -- assume_migrated_upto_version(0) -> 0.0942s [earlz@earlzarch avp_msql_migrations]$ So what is the problem? Does the Foreigner plugin not work in SQL Server? If it didn't I'd expect to see an error or something...

  • Linq : problem with primary key

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • How to secure licensekey generation

    - by Jakob Gade
    Scenario, simplified for brevity: A developer creates an application for a customer. The customer sells this app to end-users. The app requires a license key to run, and this key is generated by the customer for each end-user with a simple tool created by the developer. The license key contains an expiry date for the license and is encrypted so the end-user can’t tamper with it. The problem here is that the developer (or anybody who has a copy of the license key generator) can easily create valid license keys. Should this generator fall into the wrong hands, it could spell disaster for the customers business. Ideally, the customer would have to use a password to create new license keys. And this password would be unknown to the developer, and somehow baked into the decryption algorithm in the application so it will fail if an attempt to use an unauthorized key is made. How would you implement a solution for this problem that is both transparent and secure?

  • integriting facebook login button with Facebooker (rails plugin)

    - by dexterdeng
    I was integriting login-button with Facebooker, as I wanted to use facepile and customise the facebook login button, so I have to use facebook js sdk. I used the facebooker to connect facebook. now I found a issue. window.fbAsyncInit = function() { FB.init({ appId: '<%=Facebooker.api_key%>', status: true, cookie: true, xfbml: true }); }; (function() { var e = document.createElement('script'); e.type = 'text/javascript'; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; e.async = true; document.getElementById('fb-root').appendChild(e); }()); function fblogin(){ var pearms = "email,user_birthday,friends_location,offline_access,publish_stream,read_friendlists,user_birthday,user_location"; FB.getLoginStatus(function(response) { if (response.session) { // logged in and connected user, someone you know window.location = "http://domain/account/link_user_accounts"; return true; } else { // no user session available, someone you dont know FB.login(function(response) { if (response.session) { if (response.perms) { // after logged in the facebook account. $.inspect(response.perms);//return all these perms I expected. it should be fine there. window.location = "http://domain/account/link_user_accounts"; } return true; } else { return false; } },"email,user_birthday,friends_location,offline_access,publish_stream,read_friendlists"); } }) }; Let's say if the api_key is "1111111111". take a look at this line: " ` if (response.session) { if (response.perms) { $.inspect(response.perms); " now I was trying to login , call fblogin() , I'm sure that the response.perms equal to the perms I expected. (btw, at that time, I have a facebook plugin named facepile works too, it showed my friends after I called fblogin() and connected to facebook by typing my email and password ). so now it should run window.location = "http://domain/account/link_user_accounts"; yes, this line run. but the facebook_session can't build successfully. after digging the facebooker's code, I found this from the rails plugin facebooker: def create_facebook_session secure_with_facebook_params! || secure_with_cookies! || secure_with_token! end mostly, it would run secure_with_cookies! , and if the cookies with keys as "fbs_#{Facebooker.api_key}","#{Facebooker.api_key}_ss", "#{Facebooker.api_key}_session_key",.. created, then the facebook_session can be created. but these cookies can't be created after I logged in facebook until I refresh the current page by hand . I noticed if I refresh the page, the cookies with these keys added to the browser. but why they can't be added after I logged in facebook at once? I need these keys to create facebook_session. did I forgot something excepted these code I pasted? anybody help? thank you very much!

  • Using boost unordered map

    - by Amrish
    Guys, I am using dynamic programming approach to solve a problem. Here is a brief overview of the approach Each value generated is identified using 25 unique keys. I use the boost::hash_combine to generate the seed for the hash table using these 25 keys. I store the values in a hash table declared as boost::unordered_map<Key_Object, Data_Object, HashFunction> hashState; I did a time profiling on my algorithm and found that nearly 95% of the run time is spent towards retrieving/inserting data into the hash table. These were the details of my hash table hashState.size() 1880 hashState.load_factor() 0.610588 hashState.bucket_count() 3079 hashState.max_size() 805306456 hashState.max_load_factor() 1 hashState.max_bucket_count() 805306457 I have the following two questions Is there anything which I can do to improve the performance of the Hash Table's insert/retrieve operations? C++ STL has hash_multimap which would also suit my requirement. How does boost libraries unordered_map compare with hash_multimap in terms of insert/retrieve performance.

  • Generate reasonable length license key with asymmetric encryption?

    - by starkos
    I've been looking at this all day. I probably should have walked away from it hours ago; I might be missing something obvious at this point. Short version: Is there a way to generate and boil down an asymmetrically encrypted hash to a reasonable number of unambiguous, human readable characters? Long version: I want to generate license keys for my software. I would like these keys to be of a reasonable length (25-36 characters) and easily read and entered by a human (so avoid ambiguous characters like the number 0 and the capital letter O). Finally--and this seems to be the kicker--I'd really like to use asymmetric encryption to make it more difficult to generate new keys. I've got the general approach: concatenate my information (user name, product version, a salt) into a string and generate a SHA1() hash from that, then encrypt the hash with my private key. On the client, build the SHA1() hash from the same information, then decrypt the license with the public key and see if I've got a match. Since this is a Mac app, I looked at AquaticPrime, but that generates a relatively large license file rather than a string. I can work with that if I must, but as a user I really like the convenience of a license key that I can read and print. I also looked at CocoaFob which does generate a key, but it is so long that I'd want to deliver it as a file anyway. I fooled around with OpenSSL for a while but couldn't come up with anything of a reasonable length. So...am I missing something obvious here? Is there a way to generate and boil down an asymmetrically encrypted hash to a reasonable number of unambiguous, human readable characters? I'm open to buying a solution. But I work on a number of different of platforms, so I'd want something portable. Everything I've looked at so far has been platform specific. Many, many thanks for a solution! PS - Yes, I know it will still be cracked. I'm trying to come up with something reasonable that, as a user, I would still find friendly.

  • Calling SetWindowsHookEx inside VS2008 debugger always returns NULL

    - by SoMoS
    we're working on a .Net application that does a low level keyboard hook. When we call the SetWindowsHookEx running inside the debugger the call always fail. When running from the compiled executable everything works fine. If we attach to the processs the the SetWindowsHookEx has been called everything works too. I've read somewhere (I can not remember) that VS already does a low level keyboard hook but this shouldn't be a problem as there is the CallNextHook function. Someone knows what's happening? EDIT: The code is pretty straigfoward, the exception is thrown inside debugger but not outside. Public Sub New() m_callback = New NativeMethods.KeyboardHookDelegate(AddressOf KeyboardCallback) End Sub Public Sub Start() m_handle = NativeMethods.SetWindowsHookEx(NativeMethods.HookType.WH_KEYBOARD_LL, m_callback, Marshal.GetHINSTANCE(Reflection.Assembly.GetExecutingAssembly().GetModules()(0)).ToInt32, 0) If m_handle = 0 Then Throw New Exception() End If End Sub

  • Confusion on using django socialauth

    - by Fedor
    http://github.com/uswaretech/Django-Socialauth/tree/master/socialauth/ I'm a bit confused on how I should use this. Of course, I read the notes at the bottom but I'm a Django novice so I'll need a little hand holding. The structure of this looks like a project structure since it contains a urls.py but I'm also aware that applications can also have that. It also has a manage.py which leads me to believe it's a project ( plus the subdirectories ). So should I just be integrating portions of this into my existing project? This isn't an application, right? The README also mentions grabbing API Keys. So if I want a standard interface where you click on a google/yahoo logo and it forwards itself via Javascript to the authentication page where you login if you already aren't logged in, kicks you back to your own page, would I need API keys? Any other special tips are appreciated.

  • Help with linq to sql compiled query

    - by stackoverflowuser
    Hi I am trying to use compiled query for one of my linq to sql queries. This query contains 5 to 6 joins. I was able to create the compiled query but the issue I am facing is my query needs to check if the key is within a collection of keys passed as input. But compiled queries do not allow passing of collection (since collection can have varying number of items hence not allowed). For instance input to the function is a collection of keys. Say: List<Guid> InputKeys List<SomeClass> output = null; var compiledQuery = CompiledQueries.Compile<DataContext, IQueryable<SomeClass>>( (context) => from a in context.GetTable<A>() where InputKeys.Contains(a.Key) select a); using(var dataContext = new DataContext()) { output = compiledQuery(dataContext).ToList(); } return output; Is there any work around or better way to do the above?

  • asp.net MVC - how to get complete local and global resources

    - by Buthrakaur
    I'm localizing application and need to provide JSON representation of local and global resources for JS part of application for all views. My current idea is I'd implement HtmlHelper extension methods like GetLocalResourcesJSON/GetGlobalResourcesJSON which should encode all resource keys+values and return them JSON encoded as string (I'd implement caching as well). At the moment I'm able to retrieve single specific key from global or local resource belonging to current view (using httpContext.GetGlobalResourceObject/GetLocalResourceObject), but I'm not able to find out how to retrieve whole resource object and iterate all its keys+values. Is there any method how to achieve this? it looks like ResourceProviderFactory could be the the key to this problem, but it's not accessible publicly anywhere. I could instantiate ResourceExpressionBuilder and use reflection to retrieve the provider using GetLocal/GlobalResourceProvider() methods, but I don't like using reflection here at all...

  • Reinstalling Applications after Win 7 installation [closed]

    - by Don Oxley
    I'm preparing to upgrade to Win 7 and am trying to ensure that I will be able to reinstall all the relevant applications. Since most applications require product keys, I'm curious if the installation process for Win 7 preserves those keys in any way (say for Office 2007,...) or do I have to locate and reenter every key? Second, for appications that require a key and then check with their home server (Norton Internet Security, for example). Even if I have the key, how do I convince the server that I'm not trying to reuse an application that has a single use license? Thanks, --Don

  • Is perl's each function worth using?

    - by eugene y
    From perldoc -f each we read: There is a single iterator for each hash, shared by all each, keys, and values function calls in the program; it can be reset by reading all the elements from the hash, or by evaluating keys HASH or values HASH. The iterator is not reset when you leave the scope containing the each(), and this can lead to bugs: my %h = map { $_, 1 } qw(1 2 3); while (my $k = each %h) { print "1: $k\n"; last } while (my $k = each %h) { print "2: $k\n" } Output: 1: 1 2: 3 2: 2 What are the common workarounds for this behavior?

  • IntelliSense has forgotten my code snippets!

    - by David
    Hi all I have a stack of code snippets imported into Visual Studio. Just recently, they have stopped displaying in Intellisense. If the keyboard shortcut doesn't bring up anything else on IntelliSense, then I can tab and the code snippet is inserted just fine. However, if the keyboard shortcut for the snippet happens to also bring up other items in IntelliSense, tabbing will select the first of those items, so I actually can't use the code snippet at all! Does anyone have any ideas why IntelliSense would be unable to list my code snippet shortcuts? I started using ReSharper recently, but that wouldn't be the problem surely?! Thanks for your help David

  • ASP.NET MVC 2 strange behavior

    - by Voice
    Hi Recently I installed VS 2010 Release (migrated from RC) and my MVC application is not working anymore. More concrete: I have a wizard with several steps for new customer account creation (Jquery form wizard, but it doesn't really matter). Each step contains a typed partial View for each part of account: Company, Customer, Licence, etc. When I submit the form I see really strange thing in ModelState. There are duplicate keys for Company: with "Company" prefix and without it. Something like this: [6] "Company.Phone" string [12] "Phone" string My model state for all these keys is not valid because Company is actually null and validation fails. When it was RC there were no such keys with "Company" prefix. So these keys in ModelState with prefix "Company" appeared after I installed VS Release. Here is my code: Main View <div id="registerSteps"> <div id="firstStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CustomerInfo) %></legend> <% Html.RenderPartial("CustomerInfo", ViewData["newCust"]); %> </fieldset> </div> <div id="secondStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CompanyInfo) %></legend> <% Html.RenderPartial("CompanyInfo", ViewData["newComp"]); %> </fieldset> </div> <div id="thirdStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.LicenceInfo) %></legend> <% Html.RenderPartial("LicenceInfo", ViewData["newLic"]); %> </fieldset> </div> <div id="lastStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.PrivacyStatement) %></legend> <% Html.RenderPartial("PrivacyStatementInfo"); %> </fieldset> </div> <div id="registerNavigation"> <input class="navigation_button" value="Back" type="reset"/> <input class="navigation_button" value="Next" type="submit"/> </div> </div> Two partial views (to show that they are actually identical): Company: <div id="dCompanyInfo"> <div> <div> <%=Html.LocalizableLabelFor(company => company.Name, Register.CompanyName) %> </div> <div> <%=Html.TextBoxFor(company => company.Name) %> <%=Html.ValidationMessageFor(company => company.Name) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Phone, Register.Phone) %> </div> <div> <%=Html.TextBoxFor(company => company.Phone) %> <%=Html.ValidationMessageFor(company => company.Phone) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Fax, Register.Fax) %> </div> <div> <%=Html.TextBoxFor(company => company.Fax) %> <%=Html.ValidationMessageFor(company => company.Fax) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Size_ID, Register.CompanySize) %> </div> <div> <%=Html.ValueListDropDown(company => company.Size_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["CompSize"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Size_ID) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Industry_ID, Register.Industry) %> </div> <div> <%=Html.ValueListDropDown(company => company.Industry_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["Industry"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Industry_ID) %> </div> </div> </div> And for Customer <div id="dCustomerInfo"> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Email, Register.Email) %> </div> <div> <%=Html.TextBoxFor(customer => customer.Email) %> <%=Html.ValidationMessageFor(customer => customer.Email) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Male, Register.Gender) %> </div> <div> <%=Html.ListBoolEditor(customer => customer.Male, Register.Male, Register.Female, Register.GenderOptionLabel) %> <%=Html.ValidationMessageFor(customer => customer.Male) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.FirstName, Register.FirstName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.FirstName) %> <%=Html.ValidationMessageFor(customer => customer.FirstName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.LastName, Register.LastName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.LastName) %> <%=Html.ValidationMessageFor(customer => customer.LastName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Role_ID, Register.Role) %> </div> <div> <%=Html.ValueListDropDown(customer => customer.Role_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["OrgRole"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(customer => customer.Role_ID) %> </div> </div> </div> There are some home made extension methods, but they worked pretty well in previous version (VS RC). Html which is generated is also ok, no "Company.Phone"-like stuff. So I wonder, where all these keys with "Company" came from and what can I do with that? I appreciate any solution.
