  • MYSQL: Limit Word Length for MySql Insert

    - by elmaso
    Hi, every search query is saved in my database, but I want to Limit the Chracterlength for one single word: odisafuoiwerjsdkle -- length too much -- dont write in the database my actually code is: $search = $_GET['q']; if (!($sql = mysql_query ('' . 'SELECT * FROM `history` WHERE `Query`=\'' . $search . '\''))) { exit ('<b>SQL ERROR:</b> 102, Cannot write history.'); ; } while ($row = mysql_fetch_array ($sql)) { $ID = '' . $row['ID']; } if ($ID == '') { mysql_query ('' . 'INSERT INTO history (Query) values (\'' . $search . '\')'); } if (!($sql = mysql_query ('SELECT * FROM `history` ORDER BY `ID` ASC LIMIT 1'))) { exit ('<b>SQL ERROR:</b> 102, Cannot write history.'); ; } while ($row = mysql_fetch_array ($sql)) { $first_id = '' . $row['ID']; } if (!($sql = mysql_query ('SELECT * FROM `history`'))) { exit ('<b>SQL ERROR:</b> 102, Cannot write history.'); ; }

  • Form validation

    - by kielie
    Hi guys, I need to create a form that has many of the same fields, that have to be inserted into a database, but the problem I have is that if a user only fills in one or two of the rows, the form will still submit the blank data of the empty fields along with the one or two fields the user has filled in. How can I check for the rows that have not been filled in and leave them out of the query? or check for those that have been filled in and add them to the query. . . The thank_you.php file will capture the $_POST variables and add them to the database. <form method="post" action="thank_you.php"> Name: <input type="text" size="28" name="name1" /> E-mail: <input type="text" size="28" name="email1" /> <br /> Name: <input type="text" size="28" name="name2" /> E-mail: <input type="text" size="28" name="email2" /> <br /> Name: <input type="text" size="28" name="name3" /> E-mail: <input type="text" size="28" name="email3" /> <br /> Name: <input type="text" size="28" name="name4" /> E-mail: <input type="text" size="28" name="email4" /> <input type="image" src="images/btn_s.jpg" /> </form> I am assuming that I could use javascript or jQuery to accomplish this, how would I go about doing this? Thanx in advance for the help.

  • SugarmCRM REST API always returns "null"

    - by TuomasR
    I'm trying to test out the SugarCRM REST API, running latest version of CE (6.0.1). It seems that whenever I do a query, the API returns "null", nothing else. If I omit the parameters, then the API returns the API description (which the documentation says it should). I'm trying to perform a login, passing as parameter the method (login), input_type and response_type (json) and rest_data (JSON encoded parameters). The following code does the query: $api_target = "http://example.com/sugarcrm/service/v2/rest.php"; $parameters = json_encode(array( "user_auth" => array( "user_name" => "admin", "password" => md5("adminpassword"), ), "application_name" => "Test", "name_value_list" => array(), )); $postData = http_build_query(array( "method" => "login", "input_type" => "json", "response_type" => "json", "rest_data" => $parameters )); echo $parameters . "\n"; echo $postData . "\n"; echo file_get_contents($api_target, false, stream_context_create(array( "http" => array( "method" => "POST", "header" => "Content-Type: application/x-www-form-urlencoded\r\n", "content" => $postData ) ))) . "\n"; I've tried different variations of parameters and using username instead of user_name, and all provide the same result, just a response "null" and that's it.

  • How to increase Remote Desktop resolution?

    - by BugAlert
    I'm using Windows 7 on a PC and connect to it via Remote Desktop Connection for Mac by MS, using a Mac. On the Mac, I have a 27" Display with 2560 x 1440 px resolution. The PC has a high performance graphics card (one of those that needs an additional power supply). Both machines are connected via network cable to a router. So network should be insanely fast. However, the max resolution I can get is 1400 x 1050. The PC just has a old and bad 21" monitor connected to it. How can I increase the resolution to 2560 x 1440 to work fullscreen with the Apple LED Cinema Display via Remote Desktop? Maybe I shouldn't even ask, because I already experience some lag at the low resolution of 1400 x 1050. But I guess this can be resolved as well?

  • Blackberry Access to Powered Down Exchange

    - by Sam Cogan
    I work with a company (it's more of a charity really) who have a single Exchange Server, with a few Blackberry users, who download emails via POP3 or IMAP. They are in a developing country and so every night they turn off the Exchange server to save power. However, they now want the Blackberry users to be able to get mail at night. They have a Linux server (a rented VPS), so they are considering having the mail delivered here and then pulling this mail via a POP connector into Exchange. Therefore at night, the BES users (who will now be pulling their POP email from the Linux server) can still get their mail. Can anyone think of a better solution to this problem that I may have missed? Unfortunately there is no convincing the company to leave the machine on overnight.

  • Fastest way to become a MySQL expert?

    - by Kerry
    I have been using MySQL for years, mainly on smaller projects until the last year or so. I'm not sure if it's the nature of the language or my lack of real tutorials that gives me the feeling of being unsure if what I'm writing is the proper way for optimization purposes and scaling purposes. While self-taught in PHP I'm very sure of myself and the code I write, easily can compare it to others and so on. With MySQL, I'm not sure whether (and in what cases) an INNER JOIN or LEFT JOIN should be used, nor am I aware of the large amount of functionality that it has. While I've written code for databases that handled tens of millions of records, I don't know if it's optimum. I often find that a small tweak will make a query take less than 1/10 of the original time... but how do I know that my current query isn't also slow? I would like to become completely confident in this field in the ability to optimize databases and be scalable. Use is not a problem -- I use it on a daily basis in a number of different ways. So, the question is, what's the path? Reading a book? Website/tutorials? Recommendations?

  • Auto-connect Bluetooth headphones in Windows 7 64bit

    - by CptSkippy
    I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

  • C# Dataset Dynamically Add DataColumn

    - by Wesley
    I am trying to add a extra column to a dataset after a query has completed. I have a database relationship of the following: Employees / \ Groups EmployeeGroups Empoyees holds all the data for that individual, I'll name the unique key the UserID. Groups holds all the groups that a employee can be a part of, i.e. Super User, Admin, User; etc. I will name the unique key GroupID EmployeeGroups holds all the associations of which groups each employee belongs too. (UserID | GroupID) What I am trying to accomplish is after querying for a all users I want to loop though each user and add what groups that user is a part of by adding a new column to the dataset named 'Groups' which is a string to insert the values of the next query to get all the groups that user is a part of. Then by user of databinding populate a listview with all employees and their group associations My code is as follows; Position 5 is the new column I am trying to add to the dataset. string theQuery = "select UserID, FirstName, LastName, EmployeeID, Active from Employees"; DataSet theEmployeeSet = itsDatabase.runQuery(theQuery); DataColumn theCol = new DataColumn("Groups", typeof(string)); theEmployeeSet.Tables[0].Columns.Add(theCol); foreach (DataRow theRow in theEmployeeSet.Tables[0].Rows) { theRow.ItemArray[5] = "1234"; } At the moment, the code will create the new column but when i assign the data to that column nothing will be assigned, what am I missing? If there is any further explination or information I can provide, please let me know. Thank you all

  • Ruby-on-Rails: Multiple has_many :through possible?

    - by williamjones
    Is it possible to have multiple has_many :through relationships that pass through each other in Rails? I received the suggestion to do so as a solution for another question I posted, but have been unable to get it to work. Friends are a cyclic association through a join table. The goal is to create a has_many :through for friends_comments, so I can take a User and do something like user.friends_comments to get all comments made by his friends in a single query. class User has_many :friendships has_many :friends, :through => :friendships, :conditions => "status = #{Friendship::FULL}" has_many :comments has_many :friends_comments, :through => :friends, :source => :comments end class Friendship < ActiveRecord::Base belongs_to :user belongs_to :friend, :class_name => "User", :foreign_key => "friend_id" end This looks great, and makes sense, but isn't working for me. This is the error I'm getting in relevant part when I try to access a user's friends_comments: ERROR: column users.user_id does not exist : SELECT "comments".* FROM "comments" INNER JOIN "users" ON "comments".user_id = "users".id WHERE (("users".user_id = 1) AND ((status = 2))) When I just enter user.friends, which works, this is the query it executes: : SELECT "users".* FROM "users" INNER JOIN "friendships" ON "users".id = "friendships".friend_id WHERE (("friendships".user_id = 1) AND ((status = 2))) So it seems like it's entirely forgetting about the original has_many through friendship relationship, and then is inappropriately trying to use the User class as a join table. Am I doing something wrong, or is this simply not possible?

  • Streaming audio to headless linux box

    - by Ralph
    I have a dual boot (Win 7 + Ubuntu) PC connected via wifi with my music collection on a local HDD. I usually use Rhythmbox on Ubuntu or Winamp on Windows to listen to my music but I'll change if I have to. I also have a Raspberry Pi (low power PC running Debian) in the living room that is usually headless and connected via ethernet. The Raspberry Pi is also connected to my living room speakers via an amp. I would like to be able to stream music from my PC over the network to the linux raspberry pi. What software can I use to do this? Some sort of audio client\server?

  • How can I disrupt my roommate's BitTorrent?

    - by bob
    We're on a 50 mb/s Comcast connection and our connection right now is coming in under 1.5 mb/s. Our roommate left for a week with BitTorrent running (Azureus client, we think). Our latency is approaching 300 ms. His door is locked up tight, and both his machine and the router for the house are located inside. I've even flipped the power breaker in the house and that barely works for 2 minutes. His laptop keeps on running, and once the cable modem and router come back up and the machine reconnects, the torrents resume in earnest. I've been running nmap and identified his IP on our LAN. Is there anything I can do over the LAN to make his torrents start to fail or slow down?

  • Getting a Specified Cast is not valid while importing data from Excel using Linq to SQL

    - by niceoneishere
    This is my second post. After learning from my first post how fantastic is to use Linq to SQL, I wanted to try to import data from a Excel sheet into my SQL database. First My Excel Sheet: it contains 4 columns namely ItemNo ItemSize ItemPrice UnitsSold I have a created a database table with the following fields table name ProductsSold Id int not null identity --with auto increment set to true ItemNo VarChar(10) not null ItemSize VarChar(4) not null ItemPrice Decimal(18,2) not null UnitsSold int not null Now I created a dal.dbml file based on my database and I am trying to import the data from excel sheet to db table using the code below. Everything is happening on click of a button. private const string forecast_query = "SELECT ItemNo, ItemSize, ItemPrice, UnitsSold FROM [Sheet1$]"; protected void btnUpload_Click(object sender, EventArgs e) { var importer = new LinqSqlModelImporter(); if (fileUpload.HasFile) { var uploadFile = new UploadFile(fileUpload.FileName); try { fileUpload.SaveAs(uploadFile.SavePath); if(File.Exists(uploadFile.SavePath)) { importer.SourceConnectionString = uploadFile.GetOleDbConnectionString(); importer.Import(forecast_query); gvDisplay.DataBind(); pnDisplay.Visible = true; } } catch (Exception ex) { Response.Write(ex.Source.ToString()); lblInfo.Text = ex.Message; } finally { uploadFile.DeleteFileNoException(); } } } // Now here is the code for LinqSqlModelImporter public class LinqSqlModelImporter : SqlImporter { public override void Import(string query) { // importing data using oledb command and inserting into db using LINQ to SQL using (var context = new WSDALDataContext()) { using (var myConnection = new OleDbConnection(base.SourceConnectionString)) using (var myCommand = new OleDbCommand(query, myConnection)) { myConnection.Open(); var myReader = myCommand.ExecuteReader(); while (myReader.Read()) { context.ProductsSolds.InsertOnSubmit(new ProductsSold() { ItemNo = myReader.GetString(0), ItemSize = myReader.GetString(1), ItemPrice = myReader.GetDecimal(2), UnitsSold = myReader.GetInt32(3) }); } } context.SubmitChanges(); } } } can someone please tell me where am I making the error or if I am missing something, but this is driving me nuts. When I debugged I am getting this error when casting from a number the value must be a number less than infinity I really appreciate it

  • Open source report framework

    - by Tiax
    I'm looking for a open source report framework for statistics. A more detailed explanation is: We have a number of tests running on different servers collecting data (for example, login time) every 5min. What we need is a framework that collects this data (or exposes web services for us to push the data into the framework) and presents it in form of graphs and so on. Does anyone know of a framework that's easy to use out of the box but has the power to grow? If you know what I mean. Thanks in advance!

  • Using VLC to Unicast High Definition Webcam over local gigabit LAN with low/zero delay

    - by Robin Day
    We're setting up a webcam "window" between two offices in the same buildilng. The two PC's are connected to the same gigabit switch. We're using VLC to stream the webcam over HTTP using the following commands. vlc dshow:// :dshow-caching="0" :dshow-size="640x480" :sout=#transcode{vcodec=h264,vb=0,scale=0}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep vlc http://192.168.0.1:8080 :http-caching="0" Even with the caching set to zero, the delay in the image is a good 2-3 seconds. The CPU usage of each pc is also maxed. I'm guessing it's the transcoding that's causing much of the delay. Can anyone give me some changes to these command lines that will reduce the transcoding power, or send the webcam over a different protocol, or anything that will reduce the delay of the cameras? Bandwidth is not an issue at all as the pc's can be connected to a dedicated switch/vlan if required.

  • Get the equivalent time between "dynamic" time zones

    - by doctore
    I have a table providers that has three columns (containing more columns but not important in this case): starttime, start time in which you can contact him. endtime, final hour in which you can contact him. region_id, region where the provider resides. In USA: California, Texas, etc. In UK: England, Scotland, etc starttime and endtime are time without timezone columns, but, "indirectly", their value has time zone of the region in which the provider resides. For example: starttime | endtime | region_id (time zone of region) | "real" st | "real" et ----------|----------|---------------------------------|-----------|----------- 03:00:00 | 17:00:00 | 1 (EGT => -1) | 02:00:00 | 16:00:00 Often I need to get the list of suppliers whose time range is within the current server time (taking into account the time zone conversion). The problem is that the time zones aren't "constant", ie, they may change during the summer time. However, this change is very specific to the region and not always carried out at the same time: EGT <= EGST, ART <= ARST, etc. The question is: 1. Is it necessary to use a webservice to update every so often the time zones in the regions? Does anyone know of a web service that can serve? 2. Is there a better approach to solve this problem? Thanks in advance. UPDATE I will give an example to clarify what I'm trying to get. In the table providers I found this records: idproviders | starttime | endtime | region_id ------------|-----------|----------|----------- 1 | 03:00:00 | 17:00:00 | 23 (Texas) 2 | 04:00:00 | 18:00:00 | 23 (Texas) If I execute the query in January, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +1 hour Server time = 02:00:00 I should get the following results: idproviders = 1 If I execute the query in June, with this information: Server time (UTC offset) = 0 hours Texas providers (UTC offset) = +2 hours (their local time has not changed, but their time zone has changed) Server time = 02:00:00 I should get the following results: idproviders = 1 and 2

  • One bigger Virtual Machine distributed across many Nodes [on hold]

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- (In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes) After some comments... Is it a language barrier, or? This is only my 'virtual environment'. If we imagine this virtual machines are a separate Nodes (e.g. every has 4 cores) the OpenStack is still the same, right? Can I run one Virtual Machine across many Nodes with OpenStack? Is it possible to aggregate the computation power of separate machines in one virtual distributed operating system?

  • sql server mdf file database attachment

    - by jnsohnumr
    hello all i'm having a bear of a time getting visual studio 2010 (ultimate i think) to properly attach to my database. it was moved from original spot to #MYAPP#/#MYAPP#.Web/App_Data/#MDF_FILE#.mdf. I have three instances of sql server running on this machine. i have tried to replace the old mdf file with my new one and cannot get the connectionstring right for it. what i'm really wanting to do is to just open some DB instance, run a DB create script. Then I can have a DB that was generated via my edmx (generate database from model) in silverlight business application (c#) right now, when i go to server explorer in VS, choose add new connection, choose MS SQL Server Database FIle (SqlClient), choose my file location (app_data directory), use windows authentication, and hit the Test Connection button I get the following error: Unable to open the physical file "". Operating system error 5: "5(Access Denied.)". An attempt to attach to an auto-named database for file"" failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. The mdf file was created on the same machine by connecting to (local) on the sql server management studio, getting a new query, pasting in the SQL from the generated ddl file, adding a CREATE DATABASE [NcrCarDatabase]; GO before the pasted SQL, and executing the query. I then disconnected from the DB in management studio, closed management studio, navigated to the DATA directory for that instance, and copying the mdf and ldf files to my application's app_data folder. I am then trying to connect to the same file inside visual studio. I hope that gives more clarity to my problems :). Connection string is: Data Source=.\SQLEXPRESS;AttachDbFilename=C:\SourceCode\NcrCarDatabase\NcrCarDatabase.Web\App_Data\NcrCarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True

  • Why the different coarse threaded screws?

    - by Luke
    I'm seeing more and more of these screws (pictured below), which are almost triangular. I find I can only put them into Power Supplies and PCI(e) cards in cases, but they will break/strip away if I put them into a hard drive or a standoff for a motherboard Notice the triangular shape on it? On the Root Access chat, I started asking, but no concrete answer yet. I don't assume it's a production flaw, as I've seen hundreds and replaced them with the "proper" round screws. It is coarse-threaded, not fine-threaded (i.e. for a DVD drive or floppy drive). What are they for, and why do we need them instead of the regular round ones?

  • What service can hold CPU at lowest frequency possible when on battery load under Ubuntu?

    - by vava
    When I'm running on battery even with "performance" frequency scaling governor, something regularly lowers CPU speed to it's lowest value. I don't really want that, my AC strip usually in another room so I don't really need to save power. How can I find what service doing that? laptop_mode is disabled so that's not it. Update: Looks like CPU being scaled down only if it is under load. If it is more or less idle, it could stay on any frequency pretty much forever, but once it gets loaded, it quickly jumps to it's lowest frequency. Another update: Something sets maximum frequency CPU can have. Ubuntu launchpad bug 242006

  • Black screen after scheduled resume from sleep

    - by macbirdie
    I have a problem with my two Windows 7 setups at home. Whenever a scheduled task wakes up the machines from sleep, a black screen with a mouse cursor appears. If I move the mouse or press any key, desktop appears. The biggest problem is that during that black screen phase the display, sometimes even the PC too, doesn't go to stand by after a set period of time in power settings. If I get the desktop to show up, standby functions work fine. Display goes blank after a few minutes and as soon as the task doesn't need the PC, it goes back to sleep. It's frustrating that this "feature" is wasting energy and keeps lighting up the pc in the middle of the night for me to find it that way after I wake up. I found a handful of threads on the intertubes about the issue, but there were no answers in any of them. It sometimes happens in my XP machine at work as well.

  • How to charge an iPhone on a Windows PC without Installing iTunes

    - by Martin Hollingsworth
    I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

  • Can one connection get details of another? Or, how can I get the most detailed pending transaction

    - by bob-the-destroyer
    Is there a Mysql statement which provides full details of any other open connection or user? For this particular case, on myisam tables specifically. Looking at Mysql's SHOW TABLE STATUS documentation, it's missing some very important information for my purpose. For example: remote odbc connection one is inserting several thousand records, which due to a slow connection speed can take up to an hour. Tcp connection two, using PHP on the server's localhost, is running select queries with aggregate functions on that data. Before allowing connection two to run those queries, I'd like connection two to first check to make sure there's no pending inserts on any other connection on those specific tables so it can instead wait until all data is available. If the table is currently being written to, I'd like to spit back to the user of connection two an approximation of how much longer to wait based on the number of pending inserts. Ideally by table, I'd like to get back using a query the timestamp when connection one began the write, total inserts left to be done, and total inserts already completed. Instead of insert counts, even knowing number of bytes written and left to write would work just fine here. Obviously since connection two is a tcp connection via a PHP script, all I can really use in that script is some sort of query. I suppose if I have to, since it is on localhost, I can exec() it if the only way is by a mysql command line option that outputs this info, but I'd rather not. I suppose I could simply update a custom-made transaction log before and after this massive insert task which the PHP script can check, but hopefully there's already a built-in Mysql feature I can take advantage of.

  • Samsung TV connected to PC for Powerpoint

    - by Skaughty
    I have a 42" Samsung LCD TV connected to a Dell computer with a PCI Radion 9000 via a 35' VGA cable. It's purpose is to run power point presentations over the TV for our retail store. I have tried every combination of button clicking on the video card options, and everything on the TV, and I still get black bars on the top and bottom of the image. It looks like I am watching a old wide screen movie on a full screen TV. The TV's suggested resolution is 1024x768, and that is what the output is set to. I have tried this with a nVida PCI card as well with the same results.
