  • How can I get Dashcode to open JSP files?

    - by user332000
    A simple tools question but it's driving me nuts. I have some .jsp files on my computer that I associated with Dashcode, figuring it would be a suitable editor. But when I try to open the files, all I get is a dialog box that says, "Dashcode cannot open files of this type". I thought there'd be an easy way to fix this but I can't find it. Nowhere in Dashcode's preferences can I find any list of valid file extensions. I poked around its resources folder for a while and couldn't find it there either. The Dashcode menubar is visible when the error is up, so I'm guessing that this is Dashcode itself complaining that it cannot open this file rather than the OS preventing it from trying. How exactly does this work? Is Dashcode really just hard-coded to recognize only files of certain types by their file extension? Isn't there a way to change it? Thanks, Frank

  • How does the NSAutoreleasePool autorelease pool work?

    - by jsumners
    As I understand it, anything created with an alloc, new, or copy needs to be manually released. For example: int main(void) { NSString *string; string = [[NSString alloc] init]; /* use the string */ [string release]; } My question, though, is wouldn't this be just as valid?: int main(void) { NSAutoreleasePool *pool; pool = [[NSAutoreleasePool alloc] init]; NSString *string; string = [[[NSString alloc] init] autorelease]; /* use the string */ [pool drain]; }

  • .NET values lookup

    - by Maciej
    Hi, I have a feeling of missing something obvious. UDP receiver application. It holds a collection of valid UDP sender IPs - only guys with IP on that list will be considered. Since that list must be looked at on every packet and UDPs are so volatile, that operation must be maximum fast. Good choice is Dictionary but it is a key-value structure and what I actually need here is a dictionary-like (hash lookup) key only structure. Is there something like that? Small annoyance rather than a bug but still. I can still use Dictionary Thanks, M.

  • Trying to parse xml, but xmldocument.loadxml() is trying to download?

    - by maxp
    I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

  • Using svn with xampp for php projects

    - by idrish
    I have heard a lot about version control and would like to work on it. I read some tutorials about the same. However i am not quite sure how svn works with xampp. I have installed svn, Tortoise svn and made the necessary changes in xampp. For instance i copied the two required modules to c:/xampp/apache/modules and also made changes to the conf file in apache. Here are the changes made in c:/xampp/apache/conf/httpd.conf. # Configure Subversion repository <Location /svn> DAV svn SVNPath “C:\svn” AuthType Basic AuthName “Subversion repository” AuthUserFile “c:\svn_conf\passwd” Require valid-user </Location>t I created the repository at c:/svn and also created the password file. However when i visit http:/localhost/svn i get a 404 page not found error. Where am i going wrong. what am i missing.? Any pointers?? Thanks in advance.

  • Counting problem: possible sudoko tables?

    - by Sorush Rabiee
    Hi, I'm working on a sudoko solver. my method is using a game tree and explore possible permutations for each set of digits by DFS Algorithm. in order to analyzing problem, i want to know what is the count of possible valid and invalid sudoko tables? - a 9*9 table that have 9 one, 9 two, ... , 9 nine. (this isn't exact duplicate by this question) my solution is: 1- First select 9 cells for 1s: (*) 2- and like (1) for other digits (each time, 9 cells will be deleted from remaining available cells): C(81-9,9) , C(81-9*2,9) .... = 3- finally multiply the result by 9! (permutation of 123456789 in (*)) this is not equal to accepted answer of this question but problems are equivalent. what did i do wrong?

  • Ramifications of CheckForIllegalCrossThreadCalls=false

    - by Ron Skufca
    I recently updated an application from VS2003 to VS2008 and I knew I would be dealing with a host of "Cross-thread operation not valid: Control 'myControl' accessed from a thread other than the thread it was created on" I am handling this in what I beleive is the correct way (see code sample below). I am running into numerous controls that are going to need a similar fix. Not wanting to have similar code for every label, textbox etc.. that are being accessed by a non UI thread. What are the ramifications of just setting the CheckForIllegalCrossThreadCalls = false for the entire app? I found a CodeProject article with various workarounds and a warning at the bottom to NOT set the property. I am looking for other opinions/experiences on this issue. private void ShowStatus(string szStatus) { try { if (this.statusBar1.InvokeRequired) { BeginInvoke(new MethodInvoker(delegate() { ShowStatus(szStatus); })); } else { statusBar1.Panels[0].Text = szStatus; } } catch (Exception ex) { LogStatus.WriteErrorLog(ex, "Error", "frmMNI.ShowStatus()"); } }

  • Java multi Generic collection parameters complie error

    - by Geln Yang
    Hi, So strange!Please have a look the code first: public class A { } public class B extends A { } public class C extends A { } public class TestMain { public <T extends A> void test(T a, T b) { } public <T extends A> void test(List<T> a, List<T> b) { } public static void main(String[] args) { new TestMain().test(new B(), new C()); new TestMain().test(new ArrayList<B>(), new ArrayList<C>()); } } The statement "new TestMain().test(new ArrayList(), new ArrayList())" get a "Bound mismatch" compile error, while "new TestMain().test(new B(), new C())" is compiled ok. Bound mismatch: The generic method test(T, T) of type TestMain is not applicable for the arguments (ArrayList, ArrayList). The inferred type ArrayList is not a valid substitute for the bounded parameter It seems the type of the second generic List parameter is limited by the Type of the first.Is it a feature or a bug of the compile program? ps, jdk:1.6,IDE:Eclipse 3.5.1

  • .net c# text box date with mask - setup

    - by flavour404
    I have a c# .net project and want an input text box for a date value. I want it to display a default value of mm/dd/yyyy and then allow users to enter valid dates. I have tried using a masked text box but it doesn't like having the above format. If i try and use //__ looks naff and so does 00/00/0000 and of course if you put in '0' like 03/11/2009 you get 3/11/29 because the 0's are deleted as part of the mask - so what is the best way to set up an input box like this, effectively with a mask, only allowing numbers, and validation (though at this point I am not so worried about that). This seems so simple and isn't. Thanks, R.

  • Cannot call scalar-valued CLR UDF from select ... from table statement

    - by Henrik B
    I have created a scalar-valued CLR UDF (user defined function). It takes a timezone id and a datetime and returns the datetime converted to that timezone. I can call it from a simple select without problems: "select dbo.udfConvert('Romance Standard Time', @datetime)" (@datetime is of course a valid datetime variable) But if I call it passing in a datetime from a table it fails: "select dbo.udfConvert('Romance Standard Time', StartTime) from sometable" (column StartTime is of course a column of type datetime) The error message is: "Cannot find either column "dbo" or the user-defined function or aggregate "dbo.udfConvert", or the name is ambiguous." This message is really for beginners that has misspelled something, but as it works in one case and not in the other, I don't think I have done any misspellings. Any ideas?

  • How to replace 'dash' with 'underscore' in an IIRF rule?

    - by jessegavin
    I have a web app which serves images based on the subdomain. We wanted to provide our users with a url like this: http://{username}.domain.com/images/myimage.jpg Instead of what we used to have: http://www.reallylongdomainname.com/users/{username}/images/myimage.jpg This makes the url shorter and less 'snoopable'. So I set up an IIRF .ini file to do some url rewriting and it works great except for the fact that some of our users folders have an underscore. And from what I've read, underscore is not a valid character in a domain name (even though IIS supports it). I want to know how I could do a find and replace in the $1 back reference so that a url like this: http://some-user.domain.com/... Could be rewritten to this: /users/some_user/.. Here's my IIRF rule. RewriteCond %{HTTP_HOST} ^(?!www)([^\.]+)\.domain\.com RewriteRule ^/(.*)$ /users/*1/$1 [L,I] Thanks for any help.

  • SQL Server 2008 - cannot register default instance MSSQLSERVER

    - by Paul Moss
    Hello, I have installed SQL Server 2008 Developer on Windows 7 64 bit. In Management Studio I cannot register the default instance MSSQLSERVER, it cannot find it although the service is running. I get the message: Cannot connect to PHOENIX\MSSQLSERVER. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) (Microsoft SQL Server, Error: 87) However Management Studio does show the SQL Server 2005 Express instance (that was installed with VS 2008 Pro) which appeared as already registered. I an using Windows Authentication as I installed it in mixed mode. Any ideas would be appreciated, many thanks paul

  • Turn a collection of headings, paragraphs and lists into one hyperlink

    Is there a valid non js way to turn a collection of headings, paragraphs and lists into one url?

  • What is the ratio of Java programmers to C#.net programmers?

    - by Vaccano
    How many Java Programmers are there to every C# programmer? I have a coworker that says it was 3:1 (3 Java to 1 C#) but it is now more like 2:1 (2 java to 1 C#) Is this valid? Is there somewhere I could go for this info? Edit: This question needs to be a bit more limited in scope. I am referring to US programmers and those who would consider their career to be more focused in one side than the other. (If you are evenly balanced then you would cancel out.)

  • How to track history of db tables that include many-to-many mapping tables?

    - by chacmool
    I have seen several questions here on tracking db history, but can't seem to find one that matches our situation. We need to track the history of several tables, some of which are many-to-many linking tables. Eg say we have this schema: EntityA id name EntityB id name ABLink A_id B_id So, tracking changes to EntityA or EntityB seems pretty straightforward. We can keep a log table with the same columns plus a date stamp and user. But what about the links? How do we maintain the set of links that are valid for a given version of the data? We need to be able to recreate a history of the data showing changes in chronological order. So if a link added or deleted, we indicate that. Etc.

  • How to not check in Eclipse specific project files?

    - by futlib
    I don't want to force people into using a specific IDE for development, so our projects look basically like this: SomeProject src lib build.xml No IDE specific files whatsoever. However, many people prefer Eclipse and it is their valid complain that it is annoyingly difficult to set up an Eclipse project from an Ant build file if that project is checked into a VCS. That's a very old bug, so I don't really expect it to be fixed soon. I don't want all those weird Eclipse project files in the project root, but if it was the only way, I would accept having the eclipse project files in a subdirectory "eclipse". I thought Eclipse's linked resources were capable of just that, but I was wrong, it doesn't really work. How do you solve this problem? Are you checking in the .settings directory. etc. into your project's root?

  • php - feof error

    - by TwixxyKit
    The file that I'm trying to read is a pgp-encrypted file. This is part of the process to decrypt it and I'm actually attempting to read the contents into a string so that I can then decrypt it . I'm not sure if that's the core problem here or not, but I'm getting an error: Warning: feof(): supplied argument is not a valid stream resource Here's the file code: if($handle = opendir($dir)) { while( false !== ($file = readdir($handle))) { if($file != "." && $file != "..") { $fhandle = fopen($file, "r"); $encrypted = ''; $filename = explode('.',$file); while(!feof($fhandle)) { $encrypted .= fread($fhandle, filesize($file)); } fclose($fhandle); $decrypted = $filename[0].'.txt'; shell_exec("echo $passphrase | $gpg --passphrase-fd 0 -o $decrypted -d $encrypted"); } } }

  • AuthLogic perishable_token resets on every request

    - by go minimal
    In my User model I have: acts_as_authentic do |c| c.perishable_token_valid_for = 30.minutes end In my Application Controller I have the standard boilerplate code: def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end Now in my view I need to see if a user is logged in: <% if current_user %> Sign Out <% else %> Sign In <% end %> On every single request, current_user is being called, and that causes a SELECT call to be made to the database to find the user, then an UPDATE call that updates the last_request_at and perishable_token even though I set perishable_token_valid_for = 30.minutes. Does anyone have a better way to see if a user is logged in without causing a SELECT and UPDATE on every single page of my app. Does anyone know why the perishable token keeps updating even if I set it to be valid for 30 minutes???

  • try catch finally

    - by gligom
    Maby this is simple for you, but for me is not. I have this code: Private int InsertData() { int rezultat = 0; try { if (sqlconn.State != ConnectionState.Open) { sqlconn.Open(); } rezultat = (int)cmd.ExecuteScalar(); } catch (Exception ex) { lblMesaje.Text = "Eroare: " + ex.Message.ToString(); } finally { if (sqlconn.State != ConnectionState.Closed) { sqlconn.Close(); } } return rezultat; } Is just for inserting a new record in a table. Even if this throw an error "Specified cast is not valid." "rezultat=(int)cmd.ExecuteScalar();" - the code is executed and the row is inserted in the database, and the execution continues. Why it continues? Maby i don't understand the try catch finally yet Smile | :) Thank you!

  • C++/CLI com-Interop: Exposing a reference type property to VBA

    - by Adam
    After long hours of investigation on exposing C# property that accepts a reference type to VBA, I concluded that it was not possible. In brief, a C# property that is of type double[] or even an object cannot be consumed in VBA like this: ' Compile Error: Function or interface marked as restricted, ' or the function uses an Automation type not supported in Visual Basic oComExposedEarlyBinding.ObjectArray = VBArray ' Run-time error 424: Object required oComExposedEarlyBinding.PlainObject = VBArray Or for more details: C# property exposed to VBA (COM) : Run-time error '424': Object required I would like to know if C++/CLI would support such an option? i.e. Allowing a reference-type property to be exposed to VBA so that a syntax like the above is valid. N.B. You can achieve this by using late binding, but losing the intellisense is not an option.

  • Good input validation loop using cin - C++

    - by Alex
    Hi there, I'm in my second OOP class, and my first class was taught in C#, so I'm new to C++ and currently I am practicing input validation using cin. So here's my question: Is this loop I constructed a pretty good way of validating input? Or is there a more common/accepted way of doing it? Thanks! Code: int taxableIncome; int error; // input validation loop do { error = 0; cout << "Please enter in your taxable income: "; cin >> taxableIncome; if (cin.fail()) { cout << "Please enter a valid integer" << endl; error = 1; cin.clear(); cin.ignore(80, '\n'); } }while(error == 1);
