  • I just deleted my backup file! How do I save it?

    - by Sammy
    I just accidentally deleted a backup file that I need to restore my system. It's an Acronis True Image TIB file. It was stored at H:\My backups and the name of the file was File_backup_2012-10-18.tib. I did a quick scan with Recuva 1.43.623 and it found the file using the recovery wizard, but it was unable to recover it. The "state" of the file is "unrecoverable". So the resulting file is 0 byte. I am trying to do a deep scan with Recuva right now but it takes a lot of time. If it should fail, what other recovery option do I have? Is there any other good file recovery software that's free to use for home users? I do have a second copy of the whole system partition, but I needed this file backup copy because it is more up to date. That's the file, right there! But why is Recuva unable to recover it?

  • Stand-alone app to enter records through forms?

    - by OverTheRainbow
    Hello I need to find a stand-alone (ie. no OpenOffice-based tools, for instance) Windows application that can present users with forms to enter records into an SQLite database. The goal is to migrate data from Excel sheets into a serverless, single-user database like SQLite. As a bonus, the application would also have a somewhat-protected admin section so that I can also use it to CRUD data with the same app, but it's not a requirement. There are a lot of applications listed on the official SQLite site: Can someone recommend one that is meant for end-users, either open- or closed-source? Thank you.

  • How to know if a MySQL UPDATE query fails because information being supplied matches data already in

    - by Mike
    I have a query where the user types a block of text in a textarea field. They are able to save this information in a database. The problem is that if they have not changed the information or if the information matches the data already in the database, I recieve a '0' for affected rows. Usually I display an error that says the query failed when there are no affected rows. How would I 'know' that the 0 affected rows is because the data already exists, so that I can display a more specific error?

  • Where I get wrong?

    - by Ole Jak
    I have PHP code like this require_once( "includes" . DIRECTORY_SEPARATOR . "constants.php"); $userID = validKey( $key ); $query = "select a.username, b.streamID from user a, streams b where a.id = b.userID;)"; $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) {die( "Database selection failed: " . mysql_error()); } $generated_table = mysql_fetch_array(mysql_query($query, $connection)); // line (*) print_r($generated_table); But PHP gives me error/worning and does not print anything out Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given on line (*) 1) Why It does not printed me anything out 2) Where am I wrong?

  • Asp.net static object behaviour

    - by Circadian
    I have the following class as part of an asp.net application. public sealed class SomeClass { private static string appId = Guid.NewGuid().ToString(); public static ReadSomethingFromDb(){} public static WriteSomethingToDb(){} } There are more than one application instances in the same application pool, and they all access the same database. I want the operations performed by the above class to be uniquely tied to the instance that performed it, hence the use of the appId. So adding a record to the database would for example contain a name, address and appId. This has been simplified for discussion purposes. Assuming that I have two instances running at mysite.a and mysite.b the above class would generate two different guids. My problem is that mysite.a sometimes produces more than one guid, which is unexpected. Thank you in advance

  • Writing different structs to a file in C++? [on hold]

    - by user58053
    I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

  • Anyone plotting SO via code_swarm?

    - by Tim Post
    Is anyone working on something to render individual questions, or SO as a whole with codeswarm? If so, can you post a link to your work that transforms SO questions into revisions that codeswarm can understand (i.e. svn?) It would be really, really cool to see SO played (as a whole) via codeswarm, so I hope to not only ask if anyone is working it, but see if anyone is interested in trying to accomplish it. Augmenting that, will database dumps be made available? EDIT: Database dumps have since been made available :) Enough with user voice, is anyone doing it? If so, what VCS did you mock?

  • What information about a user is available via PHP?

    - by Camran
    This is about a classifieds website, where anyone may post classifieds. I have a security database which I intend to fill with information about the user who posts the classifieds. I intend to record information such as IP, name, tel, email, classified_text, classified_title etc etc. The reason for all this is that sometimes people become victims of fraud (fake classifieds etc). So I wonder, what information is possible to get from the poster which may help in tracking him/her down? IP is a given, but what else could be useful? And I would much like examples of how it would be useful also, as well as the code for it please, like $_SERVER['REMOTE_ADDR']. And btw, I use PHP and have Sql as a database. Thanks

  • Trouble Starting MySL Community Server on Windows 7

    - by CodeAngel
    I have installed Netbeans 7 on my Windows 7. In addition, the MySQL Community Server 5.6.12 is installed with the MSI installer on thesame 7 PC. The MySQL server is integrated with the Netbeans IDE. However , it is not possible to start or stop the MySQL server from the command prompt or the Netbeans IDE. I am only able to start or stop the server from the Windows 7 services tool. Also , it is difficult running SQL queries from the Netbeans IDE even though it shows there is connection with the MySQL server. I have added the my.ini file to the installed directory of the MySQL server , that is : C:\Program Files\MySQL\MySQL Server 5.6 below is the my.ini file : # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE.

  • Entity Framework Security

    - by NYSystemsAnalyst
    In my organization, we are just beginning to use the Entity Framework for some applications. In the past, we have pushed developers to utilize stored procedures for all database access. In addition to helping with SQL injection, we tried to grant logins access to stored procedures only to keep security relatively tight. Although inserting, updating, and deleting are easily done through stored procedures in the EF, it appears to be difficult to use stored procedures to query data with EF. However, using LINQ or Entity SQL and allowing EF to create the queries means giving a user read access to the entire database. How have others handled this dilemma?

  • PHP Put list from Powershell into Array

    Code: $exchangesnapin = "Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010"; $output = shell_exec('powershell '.$exchangesnapin.';"get-mailboxdatabase" 2>&1'); echo( '<pre>' ); echo( $output ); echo( '</pre>' ); Result: Name Server Recovery ReplicationType ---- ------ -------- --------------- Mailbox Database 0651932265 EGCVMADTEST False None Mailbox Database 0651932266 EGCVMADTEST False None I tried with echo( $output[1] ); The result was only a letter 'N'. 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?

  • Making sure an 'int' is bound on sqlite

    - by iphone_developer
    I have a method called like this... -(void)dbUpdate:(int)forId { Which contains this sqlite to bind and update a database. sqlite3_bind_int(UPDATE_ACCOUNT, 3, forId); When I run the query, it doesn't give me an error, but it doesn't update the database either. If I change this line of code... sqlite3_bind_int(UPDATE_ACCOUNT, 3, forId); manually, to... sqlite3_bind_int(UPDATE_ACCOUNT, 3, 6); the query runs 100% fine, as expected. Changing the variable to an actual integer proves to me that the variable 'forId' isn't being passed or bound to the query properly. What am I doing wrong? How is the best way to pass an Integer (and make sure it is an Integer) into an sqlite bind? Cheers,

  • Criteria: search for two different entity classes...

    - by RoCMe
    Hi! I have a "super entity" SuperEntity and three entities ChildEntity1, ..., ChildEntity3 which extends the super class. It's easy to search for all entities in the database, i.e. we could use session.createCriteria(SuperEntity.class); It's no problem to search for one specific entity type, too, just replace the SuperEntity with any of the children to look for entities of that type. But I have a problem when allowing 'multiple choice' for the types. I.e., it could be neccessary to search all entities of type 1 and 2, but not of type 3. A first idea was to create two independent queries and join the results in a final list - but that would destroy the paging which uses offset and limit functionality of the database... Is there a possibility in Criteria to join two different queries in one single result list? Kind regards, RoCMe

  • How do I convert german dates to MySQL standard dates?

    - by Kebman
    I'm importing a CSV file with dotted german dates into a MySQL database. I want the dates in the CSV to automatically be formatted correctly to the correct data type fields used by MySQL. I'm using Sequel Pro for the import. I gather I'm supposed to use the STR_TO_DATE function, but I just can't wrap my head around how to use add value or expression. German date Here are the dates in the CSV file: DD.MM.YYYY e.g.: 28.01.1978 MySQL date Here is what I want to end up with in the database: YYYY-MM-DD e.g.: 1978-01-28 Any ideas?

  • mysql ORDER BY date_time field not sorting as expected

    - by undefined
    I have a field in my database that stores the datetime that an item was added to the database. If I want to sort the items in reverse chronological order I would expect that doing ORDER by date_added DESC would do the trick. But this seems not to work. I also tried ORDER by UNIX_TIMESTAMP(date_added) but this still did not sort the results as I would expect. I also have an auto-increment field that I can use to sort items so I will use this, but I am curious as to why ORDER by datetime was not behaving as expected. any ideas?

  • Changing populated DataTable column data types

    - by TonE
    Hi, I have a System.Data.DataTable which is populated by reading a CSV file which sets the datatype of each column to string. I want to append the contents of the DataTable to an existing database table - currently this is done using SqlBulkCopy with the DataTable as the source. However, the column data types of the DataTable need to be changed to match the schema of the target database table, handling null values. I am not very familiar with ADO.NET so have been search for a clean way of doing this? Thanks.
