  • nginx bad gateway 502 with mono fastcgi

    - by Bradley Lederholz Leatherwood
    Hello so I have been trying to get my website to run on mono (on ubuntu server) and I have followed these tutorials almost to the letter: However when my directory is not blank fastcgi logs reveal this: Notice Beginning to receive records on connection. Error Failed to process connection. Reason: Exception has been thrown by the target of an invocation. I am not really sure what this means, and depending on what I do I can get another error that tells me the resource cannot be found: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Edit: I am now getting a nginx gateway error. My nginx configuration file looks like this: server { listen 2194; server_name localhost; access_log $HOME/WWW/nginx.log; location / { root $HOME/WWW/dev/; index index.html index.html default.aspx Default.aspx Index.cshtml; fastcgi_index Views/Home/; fastcgi_pass 127.0.0.1:8000; include /etc/nginx/fastcgi_params; } } Running the entire thing with xsp4 I have discovered what the "Exception has been thrown by the target of an invocation."

  • MVC + Is validation attributes enough?

    - by ebb
    My ViewModel has validation attributes that ensure that it wont be empty etc. - Is that enough or should I let my the code contracts I have made be in the ActionResult too? Example: // CreateCaseViewModel.cs public class CreateCaseViewModel { [Required] public string Topic { get; set; } [Required] public string Message { get; set; } } // CaseController.cs [AuthWhere(AuthorizeRole.Developer)] [HttpPost] public ActionResult Create(CreateCaseViewModel model) { if(!ModelState.IsValid) { // TODO: some cool stuff? } if (string.IsNullOrWhiteSpace(model.Message)) { throw new ArgumentException("Message cannot be null or empty", model.Message); } if (string.IsNullOrWhiteSpace(model.Topic)) { throw new ArgumentException("Topic cannot be null or empty", model.Topic); } var success = false; string message; var userId = new Guid(_membershipService.GetUserByUserName(User.Identity.Name).ProviderUserKey.ToString()); if(userId == Guid.Empty) { throw new ArgumentException("UserId cannot be empty"); } Case createCase = _caseService.CreateCase(model.Topic, model.Message); if(createCase == null) { throw new ArgumentException("Case cannot be null"); } if(_caseService.AddCase(createCase, userId)) { message = ControllerResources.CaseCreateFail; } else { success = true; message = ControllerResources.CaseCreateSuccess; } return Json(new { Success = success, Message = message, Partial = RenderPartialViewToString(ListView, GetCases) }); }

  • How to handle server-client requests

    - by Layne
    Currently I'm working on a Server-Client system which will be the backbone of my application. I have to find the best way to send requests and handle them on the server-side. The server-side should be able to handle requests like this one: getPortfolio -i 2 -d all In an old project I decided to send such a request as string and the server application had to look up the first part of the string ("getPortfolio"). Afterwards the server application had to find the correct method in a map which linked the methods with the the first part of the string ("getPortfolio"). The second part ("-i 2 -d all") got passed as parameter and the method itself had to handle this string/parameter. I doubt that this is the best solution in order to handle many different requests.

  • ASP.NET MVC View Not posting back to Post method and expecting a parameterless Constructor?

I wrote an post method with no parameters and it does go into that method

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:

  • Streaming audio not working in Android

    - by user320293
    Hi, I'm sure that this question has been asked before but I've been unable to find a solid answer. I'm trying to load a streaming audio from a server. Its a audio/aac file http://3363.live.streamtheworld.com:80/CHUMFMAACCMP3 The code that I'm using is private void playAudio(String str) { try { final String path = str; if (path == null || path.length() == 0) { Toast.makeText(RadioPlayer.this, "File URL/path is empty", Toast.LENGTH_LONG).show(); } else { // If the path has not changed, just start the media player MediaPlayer mp = new MediaPlayer(); mp.setAudioStreamType(AudioManager.STREAM_MUSIC); try{ mp.setDataSource(getDataSource(path)); mp.prepareAsync(); mp.start(); }catch(IOException e){ Log.i("ONCREATE IOEXCEPTION", e.getMessage()); }catch(Exception e){ Log.i("ONCREATE EXCEPTION", e.getMessage()); } } } catch (Exception e) { Log.e("RPLAYER EXCEPTION", "error: " + e.getMessage(), e); } } private String getDataSource(String path) throws IOException { if (!URLUtil.isNetworkUrl(path)) { return path; } else { URL url = new URL(path); URLConnection cn = url.openConnection(); cn.connect(); InputStream stream = cn.getInputStream(); if (stream == null) throw new RuntimeException("stream is null"); File temp = File.createTempFile("mediaplayertmp", ".dat"); temp.deleteOnExit(); String tempPath = temp.getAbsolutePath(); FileOutputStream out = new FileOutputStream(temp); byte buf[] = new byte[128]; do { int numread = stream.read(buf); if (numread <= 0) break; out.write(buf, 0, numread); } while (true); try { stream.close(); } catch (IOException ex) { Log.e("RPLAYER IOEXCEPTION", "error: " + ex.getMessage(), ex); } return tempPath; } } Is this the correct implementation?

  • Strange behavior of std::cout &operator<<...

    - by themoondothshine
    Hey ppl, I came across something weird today, and I was wondering if any of you here could explain what's happening... Here's a sample: #include <iostream> #include <cassert> using namespace std; #define REQUIRE_STRING(s) assert(s != 0) #define REQUIRE_STRING_LEN(s, n) assert(s != 0 || n == 0) class String { public: String(const char *str, size_t len) : __data(__construct(str, len)), __len(len) {} ~String() { __destroy(__data); } const char *toString() const { return const_cast<const char *>(__data); } String &toUpper() { REQUIRE_STRING_LEN(__data, __len); char *it = __data; while(it < __data + __len) { if(*it >= 'a' && *it <= 'z') *it -= 32; ++it; } return *this; } String &toLower() { REQUIRE_STRING_LEN(__data, __len); char *it = __data; while(it < __data + __len) { if(*it >= 'A' && *it <= 'Z') *it += 32; ++it; } return *this; } private: char *__data; size_t __len; protected: static char *__construct(const char *str, size_t len) { REQUIRE_STRING_LEN(str, len); char *data = new char[len]; std::copy(str, str + len, data); return data; } static void __destroy(char *data) { REQUIRE_STRING(data); delete[] data; } }; int main() { String s("Hello world!", __builtin_strlen("Hello world!")); cout << s.toLower().toString() << endl; cout << s.toUpper().toString() << endl; cout << s.toLower().toString() << endl << s.toUpper().toString() << endl; return 0; } Now, I had expected the output to be: hello world! HELLO WORLD! hello world! HELLO WORLD! but instead I got this: hello world! HELLO WORLD! hello world! hello world! I can't really understand why the second toUpper didn't have any effect.

  • C# Combining lines

    - by Mike
    Hey everybody, this is what I have going on. I have two text files. Umm lets call one A.txt and B.txt. A.txt is a config file that contains a bunch of folder names, only 1 listing per folder. B.txt is a directory listing that contains folders names and sizes. But B contains a bunch of listing not just 1 entry. What I need is if B, contains A. Take all lines in B that contain A and write it out as A|B|B|B ect.... So example: A.txt: Apple Orange Pear XBSj HEROE B.txt: Apple|3123123 Apple|3434 Orange|99999999 Orange|1234544 Pear|11 Pear|12 XBSJ|43949 XBSJ|43933 Result.txt: Apple|3123123|3434 Orange|99999999|1234544 Pear|11|12 XBSJ|43949|43933 This is what I had but it's not really doing what I needed. string[] combineconfig = File.ReadAllLines(@"C:\a.txt"); foreach (string ccline in combineconfig) { string[] readlines = File.ReadAllLines(@"C:\b.txt"); if (readlines.Contains(ccline)) { foreach (string rdlines in readlines) { string[] pslines = rdlines.Split('|'); File.AppendAllText(@"C:\result.txt", ccline + '|' + pslines[0]); } } I know realize it's not going to find the first "if" because it reads the entire line and cant find it. But i still believe my output file will not contain what I need.

  • For-Each and Pointers in Java

    - by John
    Ok, so I'm tyring to iterate through an ArrayList and remove a specefic element. However, I am having some trouble using the For-Each like structure. When I run the following code: ArrayList<String> arr = new ArrayList<String>(); //... fill with some values (doesn't really matter) for(String t : arr) { t = " some other value "; //hoping this would change the actual array } for(String t : arr) { System.out.println(t); //however, I still get the same array here } My question in, how can I make 't' a pointer to 'arr' so that I am able to change the values in a for-each loop? I know I could loop through the ArrayList using a different structure, but this one looks so clean and readable, it would just be nice to be able to make 't' a pointer. All comments are appreciated! Even if you say I should just suck it up and use a different construct.

  • how to use a PHP Constant that gets pulled from a database

    - by Ronedog
    Can you read out the name of a PHP constant from a database and use it inside of a php variable, to display the value of the constant for use in a menu? For example here's what I'm trying to accomplish In SQL: select menu_name AS php_CONSTANT where menu_id=1 the value returned would be L_HOME which is the name of a CONSTANT in a php config page. The php config page looks like this define('L_HOME','Home'); and gets loaded before the database call. The php usage would be $db_returned_constant which has a value of L_HOME that came from the db call, then I would place this into a string such as $string = '<ul><li>' . $db_returned_constant . '</li></ul>' and thus return a string that looks like $string = '<ul><li><a href="#" onclick="path_from_db">Home</a></li></ul>'. To sum up what I'm trying to do Load a config file based on the language preference query the db to return the menu name, which is the name of a CONSTANT in the config file loaded in step one, and also retrieve the menu_link which is used in the "onclick" event. Use a php variable to hold the name of the CONSTANT Place the variable into a string that gets echo'd out to create the menu displaying the value of the CONSTANT. I hope this makes enough sense...is it even possible to use a constant like this? Thanks.

  • Benchmark of Java Try/Catch Block

    - by hectorg87
    I know that going into a catch block has some significance cost when executing a program, however, I was wondering if entering a try{} block also had any impact so I started looking for an answer in google with many opinions, but no benchmarking at all. Some answers I found were: Java try/catch performance, is it recommended to keep what is inside the try clause to a minimum? Try Catch Performance Java Java try catch blocks However they didn't answer my question with facts, so I decided to try it for myself. Here's what I did. I have a csv file with this format: host;ip;number;date;status;email;uid;name;lastname;promo_code; where everything after status is optional and will not even have the corresponding ; , so when parsing a validation has to be done to see if the value is there, here's where the try/catch issue came to my mind. The current code that in inherited in my company does this: StringTokenizer st=new StringTokenizer(line,";"); String host = st.nextToken(); String ip = st.nextToken(); String number = st.nextToken(); String date = st.nextToken(); String status = st.nextToken(); String email = ""; try{ email = st.nextToken(); }catch(NoSuchElementException e){ email = ""; } and it repeats what it's done for email with uid, name, lastname and promo_code. and I changed everything to: if(st.hasMoreTokens()){ email = st.nextToken(); } and in fact it performs faster. When parsing a file that doesn't have the optional columns. Here are the average times: --- Trying:122 milliseconds --- Checking:33 milliseconds however, here's what confused me and the reason I'm asking: When running the example with values for the optional columns in all 8000 lines of the CSV, the if() version still performs better than the try/catch version, so my question is Does really the try block does not have any performance impact on my code? The average times for this example are: --- Trying:105 milliseconds --- Checking:43 milliseconds Can somebody explain what's going on here? Thanks a lot

  • How to get Autocomplete functioanlity without a control

    - by rahulchandran
    IF you supply a list of strings to an edit control and set the autocomplete mode and source then you automatically get auto complete functionality. My question is can I get the same functioanlity in .NET somewhere without a control. In other words I want something like string[] ProgressivePartialMatch( string[] Strings, string MatchText ) and so I want the strings back that would have showed up in the auto complete so to speak

  • Why am I getting a ClassCastException here?

    - by Holly
    I'm creating an android application and i'm trying to use a PreferenceActivity. I'm getting the java.lang.ClassCastException: java.lang.String error when it gets to this line return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF); I thought it might be because I'm not converting it properly from it's string value in the EditText box to the int I need but I can't figure out how to fix this, or is that even the cause? I'm flummoxed. Here's my preference activity class: public class UserPrefs extends PreferenceActivity { //option names and default vals private static final String USER_TERM = "term_length"; private static final String USER_YEAR = "year_length"; private static final int USER_TERM_DEF = 12; private static final int USER_YEAR_DEF = 34; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } public static int getTermLength(Context context){ try{ return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF); }catch (ClassCastException e){Log.v("getTermLength", "error::: " + e); } //return 1;//temporary, needed to catch the error and couldn't without adding a return outside the block.// } public static int getYearLength(Context context){ return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_YEAR, USER_YEAR_DEF); } And here's the bit of code where I'm trying to use the the preferences inside another class: public float alterForFrequency(Context keypadContext, float enteredAmount, String spinnerPosition){ int termLength = UserPrefs.getTermLength(keypadContext); int yearLength = UserPrefs.getYearLength(keypadContext); } The complete android logcat, i've uploaded here: http://freetexthost.com/v3t4ta3wbi
