  • Asp.net error object not set to a reference

    - by Frank
    Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

  • Spring-webflow error popup tweak

    - by igorp1024
    There is a link in a spring-webflow2 based application which start different flows. Flows are shown in popup (popup=true). If the session is expired or server is unavailable, the spring-webflow shows small empty popup with "Ajax Request Error" tooltip shown on mouse over. Is it possible to tweak the popup in order to give the user an ability to either re-login or to just close the popup and retry the request? EDIT: Or maybe some ideas how to force Spring-Dojo to make a redirect to login page?

  • Error Instantiating an Inner Class in Parent's Constructor...

    - by stormin986
    In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables. Any idea what's up here??

  • How can I test Windows Error Reporting?

    - by Deneb Meketa
    My company participates in Windows Error Reporting via Winqual. We'd like to add some additional data to our crash reports, using WERRegisterMemoryBlock. Obviously we'd like to make sure this is working before we ship our next version. How can we test it? Is there a way to locally preview precisely what is going to be sent? Does this realistically reproduce what we are going to be able to retrieve from Winqual? Alternatively, can we generate a real report from a developer machine, then retrieve the report from Winqual? How would we distinguish this test case from the rest of our Winqual data?

  • Php getting too many connections error from MySQL

    - by uzioriluzan
    Hello everyone, I am using MySQL and PHP with 2 application servers and 1 database server. With the increase of the number of users (around 1000 by now), I'm getting the following error : SQLSTATE[08004] [1040] Too many connections The parameter "max_connections" is set to "1000" in my.cnf and "mysql.max_persistent" is set to -1 in php.ini. There are at most 1500 apache processes running at a time since the "MaxClients" apache parameter is equal to 750 and we have 2 application servers. Should I raise the "max_connections" to 1500 as indicated in here? Or should I set "mysql.max_persistent" to 750 (we use PDO with persistent connections for performance reasons since the database server is not the same as the application servers)? Or should I try something else? Thanks in advance!

  • Error safe/correcting resource identifier

    - by Martin
    The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?

  • Best practice for error handling in codeigniter / php apps

    - by Industrial
    Hi everyone, We're working with a new codeigniter based application that are cross referencing different PHP functions forwards and backwards from various libraries, models and such. We're running PHP5 on the server and we try to find a good way for managing errors and status reports that arises from the usage of our functions. While using return in functions, the execution is ended, so nothing more can be sent back. Right? What's the best practice to send a status information or error code upon ending execution of actual function? Should we look into using exceptions or any other approach? http://us.php.net/manual/en/language.exceptions.php

  • Delphi: Application error logging in the field

    - by mawg
    Using Delphi 7, I wonder if there is a free component which will collect diagnostic information as my application runs at a remote site and will help me to debug error reports. Maybe it records each menu item selected, control clicked, text input, etc? Maybe it just dumps the stack on a crash. Maybe it does something else ... I don't mind adding code (e.g at the start and end of each procedure), as that might generate more useful info than a fully automatic system. I am not sure if the solution ought to "phone home" or if it is enough to produce a text file which can be emailed to me. Any suggestions?

  • errorPage directive works, but error-page in web.xml doesn't?

    - by danb
    I get jsp exceptions causing a forward to my error page when I put this at the top of my JSPs... <%@ page errorPage="/error.page" %> but when I try to do it globally with web.xml like so: <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/error.page</location> </error-page> I just get a blank page... I've also tried putting /error.jsp in the location element.. but no love with that either.. I am triggering an exception with a jsp that just contains this: <%if(true)throw new RuntimeException("test exception");%> I do see the exception in the console from tomcat but I just can't get that error page to show without a directive on every jsp... am I missing something simple here?

  • Drupal Error After Logging In

    - by Kim
    Hello everyone. I'm kinda new to using drupal and i'm just wondering why I kind of get this error on my new site. See i have this website under WampServer running drupal6-16. Everytime I log in with my pre-created admin account 'admin01' pass: 'admin01' i get redirected to the WampServer localhost which appears to be unusual since the header does not have the WampServer logo. I already tried creating a new drupal website with the same database and the same thing happens. Also, I tried creating another website with a new database but I copied the other website's theme and other contents and the same thing happens. Help me please. I am losing my grip on this. :( Note: I have the same website running on one PC and i am just trying to run it on another PC by copying all its contents. The original copy is working perfectly but I can't seem to get the hook on my new copies to work on other PCs.

  • How to handle this "session failed to write file" error in PHP?

    - by alex
    I am using the Kohana 3 framework, and am using the native session driver. For some reason, occasionally the sessions fail to write to their file. Warning: session_start() [function.session-start]: open(/tmp/sess_*****, O_RDWR) failed: Permission denied (13) in /home/site/public_html/system/classes/kohana/session/native.php on line 27 I am pretty sure Kohana has its own in built error handler, but it is not triggered with this error (i.e. it shows up like a normal PHP error, not the Kohana error). Anyone that has ever used Kohana will notice this seems to have bypassed Kohana's error handling (perhaps set with set_error_handler()). Is there anyway to stop this error from appearing without switching from the native session (i.e. file based) driver? Should I just give good practice the boot and append an @ error suppressor to session_start() in the core code of Kohana? Should I relax the error_reporting()? Thanks

  • Rails view error "invalid byte sequence in US-ASCII" error after upgrading Ruby to 1.9.2

    - by Jon
    Running Rails 2.3.9 and just upgraded to Ruby 1.9.2p0. I have been putting: # encoding: utf-8 in a bunch of my .rb files where ever "£" character is used, and this seems to be working. But i just got my first view error: invalid byte sequence in US-ASCI for this line of code: <%= number_to_currency(product.price, :unit => "£", :precision => 0) %> I don't think its a coincidence that the "£" character is involved again. Any ideas on how to solve this please? Thanks

  • Args error in main method for client-server program

    - by socket
    Hi I have a client and server program, all the coding is done and compiles, the client has a GUI and the server is command line. The program uses sockets. But when I run the client to connect to the server it keeps coming with the error message: "Usage: TodoClient []", rather than connecting to the server and starting up. This is where the problem lies: public static void main(String[] args) { TodoClient client; if (args.length > 2 || args.length == 0) { System.err.println("Usage: TodoClient <host> [<port>]"); } else if (args.length == 1) { client = new TodoClient(args[0], DEFAULT_PORT); } else { client = new TodoClient(args[0], Integer.parseInt(args[1])); } } Thank You

  • Error Log states that I have MySQL connect error, yet script runs fine

    - by rob - not a robber
    Hello All, First, thanks for all the help I've received so far from StackOverflow. I've learned much. Once again, I'm posing a rudimentary question that I've searched on, but cannot find the exact answer to. Here or on PHP.net. It's sort of like what this guy asked, but not exactly: http://stackoverflow.com/questions/288603/mysql-throwing-query-error-yet-finishing-query-just-fine-why So, I saw my errorlog ballooning up when I checked my site directory and opened to notice that a bunch of errors have been recorded since I wrote this new Admin area. I know something is obviously awry with my scripting for the error to be thrown, but the weird thing is, the script actually runs through and pulls all the data I need without breaking. The log contains: PHP Warning: mysql_query() [function.mysql-query]: Access denied for user 'someuser'@'localhost' (using password: NO) in /home/mysite/adminconsole.php on line 15 I don't get that because that very line is where I setup my connection... the exact same way I do it everywhere else on the site with no problem. After that error, I have these thrown at the same time [09-Apr-2010 08:44:18] PHP Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/mysite/adminconsole.php on line 15 [09-Apr-2010 08:44:18] PHP Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/mysite/adminconsole.php on line 16 From what I read in the other guys thread, the problem is the contents of the query maybe? Maybe my query is malformed? Thanks so much for any guidance you can provide. -Rob

  • Application error: fault address 0x00012afb (Expert)

    - by Christian Almeida
    Hi, I need some "light" to get a solution. Probably there are tons of things that cause this problem, but maybe somebody could help me. Scenario: a Windows server running 24/7 a PostgreSQL database and others server applications (for processing tasks on database, etc...). There are differents servers scenarios (~30), with different hardware and windows versions (XP SP3/ WinServer, etc... all NT based). All aplications were written in Delphi7, and link to DLLs (in D7 also). After some days (sometimes a week, sometimes a couple of months), Windows begins to act strange, like not opening start menu, some buttons are missing in dialogs. And soon some applications do not open, raising a event on eventviewer: Faulting application x, version y, faulting module kernel32.dll, version 5.1.2600.5781, fault address 0x00012afb In mean while, others applications open fine, like notepad, iexplore, etc... but SOME of my applications don't, with only event log described above. But if we do not restart system, in a few days even cmd.exe stops open, (and all other applications) with same error on eventlog. I've tried to find 'what' can cause this, but with no sucess. So, and any advice will be welcome. Thanks in advance.

  • Error Handling in T-SQL Scalar Function

    - by hydroparadise
    Ok.. this question could easily take multiple paths, so I will hit the more specific path first. While working with SQL Server 2005, I'm trying to create a scalar funtion that acts as a 'TryCast' from varchar to int. Where I encounter a problem is when I add a TRY block in the function; CREATE FUNCTION u_TryCastInt ( @Value as VARCHAR(MAX) ) RETURNS Int AS BEGIN DECLARE @Output AS Int BEGIN TRY SET @Output = CONVERT(Int, @Value) END TRY BEGIN CATCH SET @Output = 0 END CATCH RETURN @Output END Turns out theres all sorts of things wrong with this statement including "Invalid use of side-effecting or time-dependent operator in 'BEGIN TRY' within a function" and "Invalid use of side-effecting or time-dependent operator in 'END TRY' within a function". I can't seem to find any examples of using try statements within a scalar function, which got me thinking, is error handling in a function is possible? The goal here is to make a robust version of the Convert or Cast functions to allow a SELECT statement carry through depsite conversion errors. For example, take the following; CREATE TABLE tblTest ( f1 VARCHAR(50) ) GO INSERT INTO tblTest(f1) VALUES('1') INSERT INTO tblTest(f1) VALUES('2') INSERT INTO tblTest(f1) VALUES('3') INSERT INTO tblTest(f1) VALUES('f') INSERT INTO tblTest(f1) VALUES('5') INSERT INTO tblTest(f1) VALUES('1.1') SELECT CONVERT(int,f1) AS f1_num FROM tblTest DROP TABLE tblTest It never reaches point of dropping the table because the execution gets hung on trying to convert 'f' to an integer. I want to be able to do something like this; SELECT u_TryCastInt(f1) AS f1_num FROM tblTest fi_num __________ 1 2 3 0 5 0 Any thoughts on this? Is there anything that exists that handles this? Also, I would like to try and expand the conversation to support SQL Server 2000 since Try blocks are not an option in that scenario. Thanks in advance.
