  • Entity Framework without Transaction?

    - by Sue
    Is there a way to use EF without transaction? I have very simple single insert and don't want to roll-back when something goes wrong as there may be a trigger logging then raising error from the DB side which I have no control over. I just want to insert then catch any exceptions but don't want to roll-back.

  • How does Blippy get its data

    - by Ali
    I was wondering how Blippy is able to get my data? It requires me to put in my bank name, bank card number and password, so is it doing a simple website scrape by logging in? My bank, however also requires a seperate passphrase as well. How does it get around that? Can urllib and such libraries be used in Python to replicate Blippy functionality? site:blippy.com

  • Parallel.For System.OutOfMemoryException

    - by Martin Neal
    We have a fairly simple program that's used for creating backups. I'm attempting to parallelize it but am getting an OutofMemoryException within an AggregateExcption. Some of the source folders are quite large, and the program doesn't crash for about 40 minutes after it starts. I don't know where to start looking so the below code is a near exact dump of all code the code sans directory structure and Exception logging code. Any advise as to where to start looking? using System; using System.Diagnostics; using System.IO; using System.Threading.Tasks; namespace SelfBackup { class Program { static readonly string[] saSrc = { "\\src\\dir1\\", //... "\\src\\dirN\\", //this folder is over 6 GB }; static readonly string[] saDest = { "\\dest\\dir1\\", //... "\\dest\\dirN\\", }; static void Main(string[] args) { Parallel.For(0, saDest.Length, i => { try { if (Directory.Exists(sDest)) { //Delete directory first so old stuff gets cleaned up Directory.Delete(sDest, true); } //recursive function clsCopyDirectory.copyDirectory(saSrc[i], sDest); } catch (Exception e) { //standard error logging CL.EmailError(); } }); } } /////////////////////////////////////// using System.IO; using System.Threading.Tasks; namespace SelfBackup { static class clsCopyDirectory { static public void copyDirectory(string Src, string Dst) { Directory.CreateDirectory(Dst); /* Copy all the files in the folder If and when .NET 4.0 is installed, change Directory.GetFiles to Directory.Enumerate files for slightly better performance.*/ Parallel.ForEach<string>(Directory.GetFiles(Src), file => { /* An exception thrown here may be arbitrarily deep into this recursive function there's also a good chance that if one copy fails here, so too will other files in the same directory, so we don't want to spam out hundreds of error e-mails but we don't want to abort all together. Instead, the best solution is probably to throw back up to the original caller of copy directory an move on to the next Src/Dst pair by not catching any possible exception here.*/ File.Copy(file, //src Path.Combine(Dst, Path.GetFileName(file)), //dest true);//bool overwrite }); //Call this function again for every directory in the folder. Parallel.ForEach(Directory.GetDirectories(Src), dir => { copyDirectory(dir, Path.Combine(Dst, Path.GetFileName(dir))); }); } }

  • log4net with .NET 4.0

    - by Jonathan
    I've thrown together some code to tinker with the new .Net 4.0/VS 2010 pieces, but I can't seem to find a build of my logging framework of choice (log4net) for 4.0, and I'm getting reference errors with the 2.0 version. Is there a 4.0 version available somewhere? I'm not asking for new features, just a version that's already been rebuilt against the new assemblies. Anyone know where I can find a build of 1.2.10 built for the 4.0 framework?

  • Sending error logs through C# desktop application

    - by Mustafa A. Jabbar
    Dear All, lately our customers are experiencing unexpected crashes. We are already logging the errors on their local machines. Is there a mechanism to enable them to "send error log" somehow when the application crashes or when unexpected behavior takes place? In other word how do I know that the application freezed or hung or crashed so I can send something, and override the normal "not responding" windows message? Regards,

  • PHP session not working with JQuery Ajax?

    - by Bolt_Head
    Update, Solved: After all this I found out that I was calling an old version of my code in the update ajax. 'boardControl.php' instead of 'boardUpdate.php' These are the kinds of mistakes that make programing fun. I'm writing a browser gomoku game. I have the ajax statement that allows the player to play a piece. $(document).ready(function() { $("td").live('click',function(){ var value = $(this).attr('id'); $.get('includes/boardControl.php',{play: value, bid: bid}); }); }); value = board square location bid = board ID Before creating a user login for player identification, the server side php had a temporary solution. It would rotate the piece state for the squares when clicked instead of knowing what player to create them for. After creating login stuff I set a session variable for the player's ID. I was hoping to read the session ID from the php during the ajax request and figure out what player they are from there. session_start(); ... $playerId = $_SESSION['char']; $Query=("SELECT p1, p2 FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $p1 = mysql_result($Result,0,"p1"); $p2 = mysql_result($Result,0,"p2"); $newPiece = 0; //*default no player if($playerId == $p1) $newPiece = 1; if($playerId == $p2) $newPiece = 2; For some reason when I run the full web app, the pieces still cycle though, even after I deleted the code to make them cycle. Furthermore, after logging in If i manually load the php page in the browser, it modifies the database correctly (where it only plays pieces belonging to that player) and outputs the correct results. It seems to me that the session is not being carried over when used with Ajax. Yet Google searches tell me that, sessions do work with Ajax. Update: I'm trying to provide more information. Logging in works correctly. My ID is recognized and I printed it out next to the board to ensure that I was retrieving it correctly. The ajax request does update the board. The values passed are correct and confirmed with firebug's console. However instead of placing pieces only for the player they belong to it cycles though the piece states (0,1,2). When manually browsing to boardUpdate.php and putting in the same values sent from the Ajax the results seen in the echo'ed response indicates that the corresponding piece is played each time as intended. Same results on my laptop after fresh load of firefox. Manually browsing to boardUpdate.php without logging in before hand leave the board unchanged (as intended when no user is found in the session). I've double checked the that session_start() is on the php files and double checked the session ID variables. Hope this extra information helps, i'm running out of ideas what to tell you. Should I load up the full code? Update 2: After checking the Ajax responce in fire-bug I realized that the 'play' request does not get a result, and the board is not updated till the next 'update'. I'm still looking into this but I'll post it here for you guys too. boardUpdate.php Notable places are: Refresh Board(line6) Place Piece(line20) function boardUpdate($turnCount) (line63) <?php session_start(); require '../../omok/dbConnect.php'; //*** Refresh Board *** if(isset($_GET['update'])) { $bid = $_GET['bid']; $Query=("SELECT turn FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $turnCount=mysql_result($Result,0,"turn"); if($_GET['turnCount'] < $turnCount) //** Turn increased { boardUpdate($turnCount); } } //*** Place Piece *** if(isset($_GET['play'])) // turn order? player detect? { $squareID = $_GET['play']; $bid = $_GET['bid']; $Query=("SELECT turn, boardstate FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $turnCount=mysql_result($Result,0,"turn"); $boardState=mysql_result($Result,0,"boardstate"); $turnCount++; $playerId = $_SESSION['char']; $Query=("SELECT p1, p2 FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $p1 = mysql_result($Result,0,"p1"); $p2 = mysql_result($Result,0,"p2"); $newPiece = 0; //*default no player if($playerId == $p1) $newPiece = 1; if($playerId == $p2) $newPiece = 2; // if($newPiece != 0) // { $oldPiece = getBoardSpot($squareID, $bid); $oldLetter = $boardState{floor($squareID/3)}; $slot = $squareID%3; //***function updateCode($old, $new, $current, $slot)*** $newLetter = updateCode($oldPiece, $newPiece, $oldLetter, $slot); $newLetter = value2Letter($newLetter); $newBoard = substr_replace($boardState, $newLetter, floor($squareID/3), 1); //** Update Query for boardstate & turn $Query=("UPDATE board SET boardState = '$newBoard', turn = '$turnCount' WHERE bid = '$bid'"); mysql_query($Query); // } boardUpdate($turnCount); } function boardUpdate($turnCount) { $json = '{"turnCount":"'.$turnCount.'",'; //** turnCount ** $bid = $_GET['bid']; $Query=("SELECT boardstate FROM board WHERE bid='$bid'"); $Result=mysql_query($Query); $Board=mysql_result($Result,0,"boardstate"); $json.= '"boardState":"'.$Board.'"'; //** boardState ** $json.= '}'; echo $json; } function letter2Value($input) { if(ord($input) >= 48 && ord($input) <= 57) return ord($input) - 48; else return ord($input) - 87; } function value2Letter($input) { if($input >= 10) return chr($input += 87); else return chr($input += 48); } //*** UPDATE CODE *** updates an letter with a new peice change and returns result letter. //***** $old : peice value before update //***** $new : peice value after update //***** $current : letterValue of code before update. //***** $slot : which of the 3 sqaures the change needs to take place in. function updateCode($old, $new, $current, $slot) { if($slot == 0) {// echo $current,"+((",$new,"-",$old,")*9)"; return letter2Value($current)+(($new-$old)*9); } else if($slot == 1) {// echo $current,"+((",$new,"-",$old,")*3)"; return letter2Value($current)+(($new-$old)*3); } else //slot == 2 {// echo $current,"+((",$new,"-",$old,")"; return letter2Value($current)+($new-$old); } }//updateCode() //**** GETBOARDSPOT *** Returns the peice value at defined location on the board. //****** 0 is first sqaure increment +1 in reading order (0-254). function getBoardSpot($squareID, $bid) { $Query=("SELECT boardstate FROM board WHERE bid='$bid'"); $Result=mysql_query($Query); $Board=mysql_result($Result,0,"boardstate"); if($squareID %3 == 2) //**3rd spot** { if( letter2Value($Board{floor($squareID/3)} ) % 3 == 0) return 0; else if( letter2Value($Board{floor($squareID/3)} ) % 3 == 1) return 1; else return 2; } else if($squareID %3 == 0) //**1st spot** { if(letter2Value($Board{floor($squareID/3)} ) <= 8) return 0; else if(letter2Value($Board{floor($squareID/3)} ) >= 18) return 2; else return 1; } else //**2nd spot** { return floor(letter2Value($Board{floor($squareID/3)}))/3%3; } }//end getBoardSpot() ?> Please help, I'd be glad to provide more information if needed.

  • FastMM log to file without FullDebugMode

    - by dmauric.mp
    I'd like to get FastMM memory leak report that shows up on app shutdown, but in a file instead of the dialog box. The idea is to use it in a release build as I have trouble reproducing the leaks. I would however prefer to not use the FullDebugMode which seems to be required for logging to a file. Am I missing anything or is this not supported ?

  • Using OpenID as the only authentication method

    - by iconiK
    I have read the other questions and they mostly talk about the security of doing so. That's not entirely my concern, mostly because the website is question is a browser-based game. However, the larger issue is the user - not every user is literate enough to understand OpenID. Sure RPX makes this pretty easy, which is what I'll use, but what if the user does not have an account at Google or Facebook or whatever, or does not trust the system to log in with an existing account? They'd have to get an account at another provide - I'm sure most will know how to do it, let alone be bothered to do it. There is also the problem of how to manage it in the application. A user might want to use multiple identities with a single account, so it's not as simple as username + password to deal with. How do I store the OpenID identities of a user in the database? Using OpenID gives me a benefit too: RPX can provide extensive profile information, so I can just prefill the profile form and ask the user to edit as required. I currently have this: UserID Email ------ --------------- 86000 [email protected] 86001 [email protected] UserOpenID OpenID ---------- ------ 86000 16733 86001 16839 86002 19361 OpenID Provider Identifier ------ -------- ---------------- 16733 Yahoo https:\\me.yahoo.com\bob#d36bd 16839 Yahoo https:\\me.yahoo.com\bigbobby#x75af 19361 Yahoo https:\\me.yahoo.com\alice#c19fd Is that the right way to store OpenID identifiers in the database? How would I match the identifier RPX gave me with one in the database to log in the user (if the identifier is known). So here are concrete questions: How would I make it accessible to users not having an OpenID or not wanting to use one? (security concerns over say, logging in with their Google account for example) How do I store the identifier in the database? (I'm not sure if the tables above are right) What measures do I need to take in order to prevent someone from logging in as another user and happily doing anything with their account? (as I understand RPX sends the identifier via HTTP, so what anyone would have to do is to just somehow grab it then enter it in the "OpenID" field) What else do I need to be aware of when using OpenID?

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system?

  • How To Create Per-Request Singleton in Pylons?

    In our Pylons based web-app, we're creating a class that essentially provides some logging functionality. We need a new instance of this class for each http request that comes in, but only one per request. What is the proper way to go about this? Should we just create the object in middleware and store in in request.environ? Is there a more appropriate way to go about this?
