  • What is the main purpose of WebExceptionStatus.Success?

    - by csharpenter
    I am a bit confused about the purpose of the enum value Success of the WebExceptionStatus enumeration. I did a search and did not find this enumeration being used outside the WebException class. This is very confusing to me. Why would an exception be used to indicate a successful action/state. Am I missing something, or did I not search thouroughly enough? Was it introduced for future functionality? Please if anyone does know its basic purpose I would be thankfull if s/he shares with us the explanation.

  • Getting information about where c++ exceptions are thrown inside of catch block?

    - by tfinniga
    I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.

  • Hoard allocator not "working"?

    - by Cowboy
    I'm trying to Hoard allocator to work, but it seems it doesn't. I have a benchmark application that does a lot of dynamic memory management. The execution time for Hoard and glibc memory manager is the same. It makes me wonder if I'm doing the right thing. What I do is... export LD_PRELOAD="/path/libhoard.so" g++ main.cpp -O3 -o bm -lpthread -lrt Shouldn't I have to link to Hoard allocator? Does it matter what path (in LD_PRELOAD) is, or can I have whatever path? I'm running Ubuntu 8.04, and g++ 4.2.4 Cheers

  • Pass C++ object to Lua function

    - by peterdemin
    Hello there. I have a C++ project, where 1 method of a 1 class changes very often. So I want to take that code from C++ to Lua. Note, I'm novice to Lua. The whole task: Bind some class methods to Lua state machine; Pass reference to class object to a function, written in Lua; Operate with passed C++ object in Lua function. I've found how to make first step with Lunar, and can't cope with second and third. I can't use SWIG and boost.

  • Find first cell in a row that contains a number?

    - by Dexter
    I'm working in Excel with an exported table such as this: |-------------------------------------------------------------------------------| | | A | B | C | D | E | F | G | H | I | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 1 | Domain | JAN | FEB | MAR | APR | MAY | Start | End | Change | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 2 | www.mydomain1.com | | 1 | 4 | 3 | 1 | 1 | 1 | 0 | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 3 | www.mydomain2.com | 2 | 4 | 12 | 18 | 23 | 2 | 23 | 21 | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 4 | www.mydomain3.com | | | 14 | 12 | | 14 | xxx | NOT FOUND | |-------------------------------------------------------------------------------| I'm trying to compare the current state (last cell) to the original cell (first cell with a value). In column I, I have the formula =IF(G2 = "xxx", "NOT FOUND", IF(H2 = "xxx", "NOT FOUND", H2 - G2)) In column H, I have the formula =IF(F2 = "", "xxx", F2) In column G, I need to find the first cell with a number. If there isn't one in that range, I need G to be "xxx". I suppose I only need to check for the first cell in the range (B2 to F2) that contains a value, not just a number. I tried using an Index and Match combo, but I couldn't quite understand it.

  • Question in Flex (parser)

    - by shkk
    Hello... I want to ask you a question about Flex, the program for parsing code. Supposing I have an instruction like this one, in the rules part: "=" BEGIN(attribution); <attribution>{var_name} { fprintf(yyout, "="); ECHO; } <attribution>";" BEGIN(INITIAL); {var_name} is a regular expression that matches a variable's name, and all I want to do is to copy at the output all the attribution instructions, such as a = 3; or b = a; My rule though cannot write with fprintf the left member of the attribution, but only = 3; or =a; One solution for that might be that, after I make the match "=" and I am in the attribution state, to go 2 positions back as to get the left operand as well. How can I do that in Flex?

  • Dump Hibernate activity to sql script file

    - by zeven
    Hi, I'm trying to log hibernate activity (only dml operations) to an sql script file. My goal is to have a way to reconstruct the database from a given starting point to the current state by executing the generated script. I can get the sql queries from log4j logs but they have more information than the raw sql queries and i would need to parse them and extract only the helpful statements. So i'm looking for a programatic way, maybe by listening the persist/merge/delete operations and accessing the hibernate-generated sql statements. I don't like to reinvent the wheel so, if anybody know a way for doing this i would appreciate it very much. Thanks in advance

  • Are all "GET" requests to JSF "Initial Request"s?

    - by Pradyumna
    Hi, In JSF 1.1, I am assuming that GET requests are treated as initial requests (resulting in the creation of a new view), and POST requests are treated as Postbacks (resulting in the restoration of the old view). However, my application is behaving differently - it restores the same old view even for GET requests. Why does this happen? Is there a way to force the creation of a new view for GET requests? (My state-saving method is 'server'. I'm using MyFaces with JSP, and I have a t:saveState on a managed bean in the view) Regards, Pradyumna

  • handle an arrray posted with $.ajax (jquery) to a webservice

    - by burktelefon
    I'm trying to post data to a webservice (asp.net 3.5), like below (two variants, one commented): var array = [3, 2, 5, 1, 7]; var jsonString = JSON.stringify(array); //var jsonString = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ] }' $.ajax({ type: "POST", url: "WebService2.asmx/AddRoute", data: jsonString, contentType: "application/json; charset=utf-8", dataType: "json", processData: "false", error: function(msg) { alert('error' + msg.toString); } }); So I need a matching webmethod to recieve it. Something like this: [WebMethod] public string AddRoute(/* xxx */) { //handle data } Could someone please elaborate on how I can fetch the data, where I've typed "xxx"? I would have thought "int[] array" would do the trick, but it's not working. Any help would be greatly appreciated :)

  • Can I modify an ASP.NET AJAX History Point?

    - by Nick
    I'm using ASP.NET 3.5 with AJAX and have enabled history on the Script Manager. I have 2 pages, Default.aspx and Default2.aspx. I'm using the AJAX History on the Default.aspx page and saving history points on the server-side. There are some dropdowns on Default.aspx that I don't want to save a history point for each change but would like to save the latest state so that when I click on a link on Default.aspx that navigates to Default2.aspx, when I click the back button on Default2.aspx to return I want the dropdowns to reflect what they were prior to clicking on the hyperlink. So what I'd like to do is modify the history point that I originally set on one of my ajax async postbacks on the client-side before the page navigates away to Default2.aspx. There is a location.hash javascript property that looks like it may do what I want but when I modify the value the Script Manager Navigate event is firing. Is there a way to prevent this event from firing? And would this then do the job?

  • Good ACL implementation in Java

    - by yonconf
    Hi All. I'm implementing a web based document management system and I'd like to implement ACLs in my system. My formal requirements are hierarchal permissions (documents inherit permissions from their folders) user groups (users can dynamically create groups and associate users with groups). Such groups can have permissions on objects in the system. My code will query permission on objects in two cases: 1. Manipulating a single document 2. Listing all documents where a manipulation is possible The latter requirement seems the achilles heel for Spring Security ACLs (their method seems likely to incur multiple DB hits for each document I manage) Anyone know of another ACL implementation? Thanks!

  • MS Access Crashed an now all Form objects and code modules are missing

    - by owlie
    I was adding a form to our Access 07 db. I copied an existing form to use as a template, renamed it, and saved it. I opened a different form to check something and Access crashed. When I reopened the database it says: "Access has detected that this database is in an inconsistent state, and will attempt to recover the database." etc. When it reopened - all forms and reports were missing. Saved queries remain. The error message states that object recovery failures will be noted in a Recovery Errors table - but this table wasn't created. The links to the be database remained intact. The database is split - I was experimenting with a form on a front-end copy which might have something to do with it. Any ideas what would cause this (I can see loosing recent work - but nixing all form objects?!) And is there any chance of recovery?

  • Waiting for ServerSocket accept() to put socket into "listen" mode

    - by inazaruk
    I need a simple client-server communication in order to implement unit-test. My steps: Create server thread Wait for server thread to put server socket into listen mode ( serverSocket.accept() ) Create client Make some request, verify responses Basically, I have a problem with step #2. I can't find a way to signal me when server socket is put to "listen" state. An asynchronous call to "accept" will do in this case, but java doesn't support this (it seems to support only asynchronous channels and those are incompatible with "accept()" method according to documentation). Of cause I can put a simple "sleep", but that is not really a solution for production code. So, to summarize, I need to detect when ServerSocket has been put into listen mode without using sleeps and/or polling.

  • Distributing cpu-bound compression jobs to multiple computers?

    - by barnaby
    The other day I needed to archive a lot of data on our network and I was frustrated I had no immediate way to harness the power of multiple machines to speed-up the process. I understand that creating a distributed job management system is a leap from a command-line archiving tool. I'm now wondering what the simplest solution to this type of distributed performance scenario could be. Would a custom tool always be a requirement or are there ways to use standard utilities and somehow distribute their load transparently at a higher level? Thanks for any suggestions.

  • How to manage memory for ios with large csv files?

    - by Pell000
    I'm new to ios development, and I'm running into issues relating to memory management and my approaches to dealing with large datasets. Right now, I am loading the csv files and storing the relevant data as objects in memory at app initialization. Some of the csv files are larger than 1MB, and in total, my app uses about 180MB of memory. This is obviously way too high of a number (unless the info I found is wrong and this is an acceptable number, then please let me know). I feel as though there is a fundamental flaw in my approach: is there a way I can avoid storing the csv files in the project itself? Or, is there a kind of "lazy" loading I can do so that I can simply look up info in the csv file, as opposed to loading all of the data from it at once? Any help would do. I think that I need a new perspective in how to manage this more efficiently.

  • Call other activities in an activity?

    - by Mohit Deshpande
    Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

  • [ADVICE] .NET Desktop Application - Client Server C#, SQL

    - by Rillanon
    Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian

  • "modal" in apple documentation

    - by Crystal
    Apple uses "modal" often in their documentation. Like dismissModalViewController in their titles of methods, or documentation like: "The UIViewController class provides the fundamental view-management model for iPhone applications. The basic view controller class supports the presentation of an associated view in addition to basic support for managing modal views and rotating views in response to device orientation changes. Subclasses such as UINavigationController and UITabBarController provide additional behavior for managing complex hierarchies of view controllers and views." I'm not sure as to what context I should think of when I see modal in the names and documentation. Any thoughts? Thanks.

  • [GWT] StackLayoutPanel and MVP

    - by Stine
    Hello! Think there might be something about this MVP approach I have completely misunderstood. Currently I am struggling to apply the MVP pattern to the part of my application consisting of a StackLayoutPanel (accordion). To me it seems natural to have a presenter and a view per stack... but how do I allow the different presenters to react when the user switch the state of the stack panel? If someone could sketch an application of the MVP pattern in the case of an accordion application I would be really, really grateful! This is really getting on my nerves! ;D Thanks a lot from Stine :)

  • MySQL table with similar column info - HELP!!!

    - by George Garman
    I have a DB with a table that is named "victim". The form that dumps the info into the table has room for two victims and therefore there is vic1_fname, vic1_lname, vic2_fname, vic2_lname, etc.. (business name, person first, person last, address, city, state, zip) a "1" and "2" of each. Now I want to search the DB and locate listed victims. This is what I have so far: $result = mysql_query( "SELECT victim.* FROM victim WHERE vic1_business_name OR vic2_business_name LIKE '%$search_vic_business_name%' AND vic1_fname OR vic2_fname LIKE '%$search_vic_fname%' AND vic1_lname OR vic2_lname LIKE '%$search_vic_lname%' AND vic1_address OR vic2_address LIKE '%$search_vic_address%' AND vic1_city OR vic2_city LIKE '%$search_vic_city%' AND vic1_state OR vic2_state LIKE '%$search_vic_state%' AND vic1_dob OR vic2_dob LIKE '%$search_vic_dob%' "); <table width="960" style="border: groove;" border=".5"> <tr><th colspan=10>You search results are listed below:</th></tr> <tr> <th>Case Number</th> <th>Business Name</th> <th>First Name</th> <th>Last Name</th> <th>DOB / Age</th> <th>Address</th> <th>City</th> <th>State</th> </tr> <?php while($row = mysql_fetch_array($result)) { ?> <tr> <td align="center"><?php print $row['vic_business_name']; ?></td> <td align="center"><?php print $row['vic_fname']; ?></td> <td align="center"><?php print $row['vic_lname']; ?></td> <td align="center"><?php print $row['vic_dob']; ?></td> <td align="center"><?php print $row['vic_adress']; ?></td> <td align="center"><?php print $row['vic_city']; ?></td> <td align="center"><?php print $row['vic_state']; ?></td> </tr> <?php } ?> </table> The info did not display in the table until I changed the table to this: <tr> <td align="center"><?php print $row['vic1_business_name']; ?></td> <td align="center"><?php print $row['vic1_fname']; ?></td> <td align="center"><?php print $row['vic1_lname']; ?></td> <td align="center"><?php print $row['vic1_dob']; ?></td> <td align="center"><?php print $row['vic1_adress']; ?></td> <td align="center"><?php print $row['vic1_city']; ?></td> <td align="center"><?php print $row['vic1_state']; ?></td> </tr> <tr> <td align="center"><?php print $row['vic2_business_name']; ?></td> <td align="center"><?php print $row['vic2_fname']; ?></td> <td align="center"><?php print $row['vic2_lname']; ?></td> <td align="center"><?php print $row['vic2_dob']; ?></td> <td align="center"><?php print $row['vic2_adress']; ?></td> <td align="center"><?php print $row['vic2_city']; ?></td> <td align="center"><?php print $row['vic2_state']; ?></td> </tr> Now it displays both rows, even if its empty. It doesn't matter if the victim was listed originally as vic1 or vic2, i just want to know if they are a victim. I hope this makes sense. I can't get it to display the way I want, line-by-line, irregardless of whether you are vic1 or vic2.

  • Is it acceptable to design my GLSurfaceView as a main control class?

    - by Omega
    I'm trying to structure a game I'm making in Android so that I have a sound, flexible design. Right now I'm looking at where I can tie my games rules engine and graphics engine together and what should be in between them. At a glance, I've been eying my implementation of GLSurfaceView, where various screen events are captured. My rationale would be to create an instance of my game engine and graphics engine here and receive events and state changes to trigger updates of either where applicable. Further to this, in the future, the GLSurfaceView implementation could also store stubs for players during a network game and implementations of computer opponents and dispatch them appropriately. Does this seem like a sensible design? Are there any kinds of improvements I can make? Thanks for any input!

  • Java FileDialog programmatically set size

    - by rwallace
    I want to display a Java FileDialog and sets its initial size to something reasonable (it doesn't show the maximize button, and a lot of users might not know you can use alt-space X instead). I tried setBounds but it didn't do anything, and I don't see a method for maximizing it; what am I missing? Update: on Windows at least, the system file dialog remembers size and maximize state even across program invocations, so the user can set it to the desired size just once and it will stay that way; that seems sufficient, so I will leave it at that.

  • PHP Put list from Powershell into Array

I believe its taking the Name column but one character at a time. $output[1] is 'N', $output[2] is 'a'. Is there any way I can get the mailbox list into array?

  • Difference between local and instance variables in ruby

    - by fflyer05
    I am working on a script that creates several fairly complex nested hash datastructures and then iterates through them conditionally creating database records. This is a standalone script using active record. After several minutes of running I noticed a significant lag in server responsiveness and discovered that the script, while being set to be nice +19, was enjoying a steady %85 - %90 total server memory. In this case I am using instance variables simply for readability. It helps knowing what is going to be re-used outside of the loop vs. what won't. Is there a reason to not use instance variables when they are not needed? Are there differences in memory allocation and management between local and instance variables? Would it help setting @variable = nil when its no longer needed?
