• Can ASP.NET be configured to run as an administrator when UAC is enabled?

  - by Steve Eisner

  I can't seem to find any information that indicates whether ASP.NET can be configured (through web.config or maybe machine.config) to run as a real administrator on a machine with UAC enabled. By this I mean, even if you set it to impersonate an Administrator account, UAC will disable that account's ability to act as an Administrator by returning a token set that hides the administrator role. For any checks such as IsInRole, the running account is effectively not an administrator at all. So ... Let's say I want to ignore all good advice and just go ahead and run a web app on Vista with administrator permissions. Is it even possible? Alternatives welcome. (Core reason for needing administrator privileges: to stop or start services that are running on that machine.)

• How to find kth minimal element in the union of two sorted arrays?

  - by Michael

  This is a homework question. They say it takes O(logN + logM) where N and M are the arrays lengths. Let's name the arrays a and b. Obviously we can ignore all a[i] and b[i] where i k. First let's compare a[k/2] and b[k/2]. Let b[k/2] a[k/2]. Therefore we can discard also all b[i], where i k/2. Now we have all a[i], where i < k and all b[i], where i < k/2 to find the answer. What is the next step?

• Local variable not being passed to partial template by render?

  - by brad

  I don't seem to be able to pass a variable to my partial template in rails (2.3.5). My code is as follows; In the main view .html.erb file: <% f.fields_for :payments do |payment_form| %> <%= render 'payment', {:f => payment_form, :t => "test" } %> <% end %> and in the _payment.html.erb file: <%= t %> produces a wrong number of arguments (0 for 1) error. The payment_form object is being passed to the partial as f without any problems. I've tried a number of variations on the above syntax (e.g. :locals => {:f => payment_form, :t => "test" } without success. I presume I'm doing something pretty basic wrong but just can't see it.

• different behavior when using re.finditer and re.match.

  - by Shahzad

  Hi, I'm working on a regex to to collect some values from a page through some script. I'm using re.match in condition but it returns false but if i use finditer it returns true and body of condition is executed. i tested that regex in my own built tester and it's working there but not in script. here is sample script. result = [] RE_Add0 = re.compile("\d{5}(?:(?:-| |)\d{4})?", re.IGNORECASE) each = ''Expiration Date:\n05/31/1996\nBusiness Address: 23901 CALABASAS ROAD #2000 CALABASAS, CA 91302\n' if RE_Add0.match(each): result0 = RE_Add0.match(each).group(0) print result0 if len(result0) < 100: result.append(result0) else: print 'Address ignore' else: None

• How to inherit from the main class in java

  - by user225269

  I have two java classes. One is NewFrame.java where the forms(buttons, textfields) are located. And the other one is Main.java where I have put the connection string for mysql: Main.java looks like this: public class Main { /** * @param args the command line arguments */ public static void main(String[] args) throws Exception { // TODO code application logic here Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/employee_record", "root", "password"); PreparedStatement statement = con.prepareStatement("select * from employee"); ResultSet result = statement.executeQuery(); } } How do I inherit from the main.java so that the declarations in it would be universally accessible to the forms in NewFrame.java? Please help. Thanks

• How to get rid of bogus changes in git?

  - by zaza

  I'm a happy user of PortableGit 1.7.0.2. Today I wanted to pull a project changes from GitHub.com repository, so I did git pull. It failed with the following message: error: Your local changes to 'main.rb' would be overwritten by merge. Aborting.. I didn't care about the local changes so I typed git reset --hard HEAD (git clean from here didn't help neither), but it didn't work. When asked for git status I was still able to see the file as modified. git diff showed me that each line of the file has been modified, while git diff -b showed no differences at all, so I guess this is a line ending issue. Which is strange because the code is only pushed from Windows machines. Anyway, the question is: how can I ignore the local, bogus changes and merge with the latest changes from the remote repository?

• Images with unknown content: Dangerous for a browser?

  - by chris_l

  Let's say I allow users to link to any images they like. The link would be checked for syntactical correctness, escaping etc., and then inserted in an <img src="..."/> tag. Are there any known security vulnerabilities, e.g. by someone linking to "evil.example.com/evil.jpg", and evil.jpg contains some code that will be executed due to a browser bug or something like that? (Let's ignore CSRF attacks - it must suffice that I will only allow URLs with typical image file suffixes.)

• Nested for_each with lambda not possible?

  - by Ela782

  The following code does not compile in VS2012, it gives error C2064: term does not evaluate to a function taking 1 arguments on the line of the second for_each (line 4 below). vector<string> v1; for_each(begin(v1), end(v1), [](string s1) { vector<string> v2; for_each(begin(v2), end(v2), [](string s2) { cout << "..."; }); }); I found some related stuff like http://connect.microsoft.com/VisualStudio/feedback/details/560907/capturing-variables-in-nested-lambdas which shows a bug (they are doing something different) but on the other hand that shows that what I print above should be possible. What's wrong with the above code?

• IDisposable, does it really matter

  - by adrianm

  Coming from C/C++ a long time ago I still have a habit of ensuring that all resources are cleaned up correctly. I always ensure Dispose is called on IDisposable classes and implement Dispose patterns in my classes containing disposable objects. However, in my environment I'm more or less the only one doing this. Others just don't understand what I'm doing and think my code is more difficult to understand. They just create database connections, open streams etc without calling Close or Dispose. Sometimes they set a local or member variable to "Nothing" at the end of a method (guess their background). My problem is that their code works just as well as mine. Code that over time creates thousands of database connection objects just works. So, ignoring any arguments about code correctness, following guidelines etc, does IDiposable really matter? Has anyone actually ran out of resources from not Disposing objects?

• % confuses python raw sql query

  Following this SO question, I'm trying to "truncate" all tables related to a certain django application using the following raw sql commands in python: cursor.execute("set foreign_key_checks = 0") cursor.execute("select concat('truncate table ',table_schema,'.',table_name,';') as sql_stmt from information_schema.tables where table_schema = 'my_db' and table_type = 'base table' AND table_name LIKE 'some_prefix%'") for sql in [sql[0] for sql in cursor.fetchall()]: cursor.execute(sql) cursor.execute("set foreign_key_checks = 1") Alas I receive the following error: C:\dev\my_project>my_script.py Traceback (most recent call last): File "C:\dev\my_project\my_script.py", line 295, in <module> cursor.execute(r"select concat('truncate table ',table_schema,'.',table_name,';') as sql_stmt from information_schema.tables where table_schema = 'my_db' and table_type = 'base table' AND table_name LIKE 'some_prefix%'") File "C:\Python26\lib\site-packages\django\db\backends\util.py", line 18, in execute sql = self.db.ops.last_executed_query(self.cursor, sql, params) File "C:\Python26\lib\site-packages\django\db\backends\__init__.py", line 216, in last_executed_query return smart_unicode(sql) % u_params TypeError: not enough arguments for format string Is the % in the LIKE making trouble?

• Static initialization of a struct with class members

  - by JS Bangs

  I have a struct that's defined with a large number of vanilla char* pointers, but also an object member. When I try to statically initialize such a struct, I get a compiler error. typedef struct { const char* pszA; // ... snip ... const char* pszZ; SomeObject obj; } example_struct; // I only want to assign the first few members, the rest should be default example_struct ex = { "a", "b" }; SomeObject has a public default constructor with no arguments, so I didn't think this would be a problem. But when I try to compile this (using VS), I get the following error: error C2248: 'SomeObject::SomeObject' : cannot access private member declared in class 'SomeObject' Any idea why?

• Why doesn't functools.partial return a real function (and how to create one that does)?

  - by epsilon

  So I was playing around with currying functions in Python and one of the things that I noticed was that functools.partial returns a partial object rather than an actual function. One of the things that annoyed me about this was that if I did something along the lines of: five = partial(len, 'hello') five('something') then we get TypeError: len() takes exactly 1 argument (2 given) but what I want to happen is TypeError: five() takes no arguments (1 given) Is there a clean way to make it work like this? I wrote a workaround, but it's too hacky for my taste (doesn't work yet for functions with varargs): def mypartial(f, *args): argcount = f.func_code.co_argcount - len(args) params = ''.join('a' + str(i) + ',' for i in xrange(argcount)) code = ''' def func(f, args): def %s(%s): return f(*(args+(%s))) return %s ''' % (f.func_name, params, params, f.func_name) exec code in locals() return func(f, args)

• Regex to match a Java method signature

  - by nitesh

  I am having this particular requirement where a method has to be identified by different regular expressions for different components. For example, there need to be a regex for return parameter, one for method name, one for argument type and one for argument name. I was able to come up with an expression till this step as follows - ([^,]+) ([^,]+)\((([^,]+) ([^,]+))\) It works well for a method signature like - ReturnType foo(Arg parameter) The regular expression identifies ReturnType, foo, Arg and parameter separately. Now the problem is that a method can have no/one/multiple arguments separated by commas. I am not able to get a repeating expression for this. Help will be appreciated.

• Django Forms save_m2m

  - by John

  Hi I have a model which has 2 many to many fields in it. one is a standard m2m field which does not use any through tables whereas the other is a bit more complecated and has a through table. I am using the Django forms.modelform to display and save the forms. The code I have to save the form is if form.is_valid(): f = form.save(commit=False) f.modified_by = request.user f.save() form.save_m2m() When i try to save the form I get the following error: Cannot set values on a ManyToManyField which specifies an intermediary model. I know this is happening when I do the form.save_m2m() because of the through table. What I'd liek to do is tell Django to ignore the m2m field with the through table but still save the m2m field without the through table. I can then go on to manually save the data for the through table field. Thanks

• silently execute a MSI package from C#

  - by Keenan Molver

  Newbie question, let me try and make this as clear as possible. I have a program that needs to silently execute a msi package (well multiple but that's not the problem) The MSI packages are contained in a folder located in the same directory as my program. I've given it a simple name of "InstallFiles" for the time being. I'm not keen on using the full path name eg. C:\my program\another directory\another directory etc because it'll be put on multiple PC's, old and new, in which case the drive letter can change. So far I have: install.StartInfo.FileName = "msiexec"; install.StartInfo.Arguments = "/i F:\\InstallFiles\\JRE.msi"; install.Start(); install.WaitForExit(); However, when its launched it only gives me the Windows Installer switch information and then terminates, how do I get it to run and how would I go about changing the file path?

• [C#] Creating standalone, console (shell) for domain-specific operations

  - by mr.b

  Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

• What non-standard behaviour features does Gmail exhibit, when it is programmatically used as a POP3 server?

  - by Mike Green

  I am trying to prepare a complete list of behaviour that Gmail POP3 exhibits, that you wouldn’t expect to generally find in a POP3 server. For example, Gmail appears to ignore the DELE (delete) command from a POP3 client. Instead, it implements its own delete and archive strategy. The purpose of preparing a list is to avoid developers testing a POP3 client against the Gmail POP3 server and then assuming that all POP3 servers behave in the same way. Can anyone provide a more complete list of non-standard behaviour?

• Drupal: what's the easiest way to let my customer to upload video thumbnails and associate them to v

  - by Patrick

  hi, my customer wants a gallery of videos and images (small thumbnails) and if you click on one of them you can see the picture / video in the overlaying lightbox). Now, I cannot install auto-generating video thumbnails because I don't have access to ffmpeg module on the server. I can only allow my customer to upload these thumbnails by himself. I'm using image and video CCK fields for each node to allow my customer images and videos. However I dunno how should I let him upload thumbnails for his videos. Should I create an additional Image CCK field for this ? Consequently, I should somehow associate the videos with the images in the design and my customer should pay attention to place them in the same order.. this is not very nice solution, but it is the only one that came to my mind so far. Furthermore, I'm using the lightbox I should somehow ignore the video thumbnails and display the videos instead... some tips ? Thanks

• How should flushing be handled in a doctrine EntityManager instance shared across different services in symfony2?

  - by Jbm

  I have defined several services in symfony 2 which persist changes to the database. These services have the doctrine instance as one of their dependencies: a.given.service: class: Acme\TestBundle\Service\AGivenService arguments: [@doctrine] If I have two different services and both of them persist objects through the EntityManager, which is obtained like this from the doctrine instance: $em = $doctrine->getEntityManager(); Would all services always share the same EntityManager? If so, how should I handle flushing if I wanted to handle all the changes in a single transaction? I have checked this: http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/transactions-and-concurrency.html and it explains how to handle different transactions in a request, but I want to achieve the opposite, which is having different changes in different services handled as a single transaction. Is there a better approach to handle multiple changes in different services? For now my best bet is having a front-end service in charge of calling the other services and doing the flushing afterwards. Backend services would persist objects but would not do any flushing.

• What can cause the language bar to disappear in a win32 application?

  - by user4484

  When I run my Win32 application the Windows language bar (which is visible in all other applications) disappears after about 5 seconds. It reappears if I quit my application or alt-tab to a different application. If I alt-tab back into my application, it disappears again after five seconds. The switch key doesn't work either. It seems as if the system somehow has concluded that my application doesn't "support" the language bar. Is there something I need to do to for the language bar to be enabled? Or something I shouldn't be doing that can cause it to disappear? The application has a single custom window (where I draw DirectX graphics). I've looked through the arguments to CreateWindow and RegisterClass as well as the window messages that I handle (instead of passing to DefWindowProc) but nothing seems to be directly related to the language bar. I've only tested this on Windows 7.

• Cannot send e-mail with rails 2.3.4(I could with 2.3.2)
