  • Recommended Tutorials for php mysql and graphs

    - by Vinit Joshi
    I need help to find a tutorial or anything to help me create a comparison chart. The user is able to search for device names. The information about the device names is in a drop down box dynamically added from the database. I want the user to be able to select two separate devices and view the devices information plotted onto a graph. I'll be grateful for keywords that I can search for or any tutorials that will help me to carry on with this task. Currently on my screen I can see the data that has been inserted into the database. This data is placed inside a table. I have so far used xhtml, php and mysql. I've tried to make the question as clear as possible so sorry if it does confuse anyone.

  • Is there any natural join replacement in SQL Server 2005?

    - by truthseeker
    Hi, I have two tables which I would like to join by ID field. I was trying to use for this "INNER JOIN". Everything would be good but there are two issues: As a result I receive twice column ID. I have to omit specifying columns which should be displayed under select statement. I would like to use there a *. I red that other sql-s have something like natural join and that is probably (or not?) an answer for my question. Unfortunately there is no join like that in SQL Server (2005). Do anybody knows any good replacement of it?

  • EF4 CTP5 Code First approach ignores Table attributes

    - by Justin
    I'm using EF4 CTP5 code first approach but am having trouble getting it to work. I have a class called "Company" and a database table called "CompanyTable". I want to map the Company class to the CompanyTable table, so have code like this: [Table(Name = "CompanyTable")] public class Company { [Key] [Column(Name = "CompanyIdNumber", DbType = "int")] public int CompanyNumber { get; set; } [Column(Name = "CompanyName", DbType = "varchar")] public string CompanyName { get; set; } } I then call it like so: var db = new Users(); var companies = (from c in db.Companies select c).ToList(); However it errors out: Invalid object name 'dbo.Companies'. It's obviously not respecting the Table attribute on the class, even though it says here that Table attribute is supported. Also it's pluralizing the name it's searching for (Companies instead of Company.) How do I map the class to the table name?

  • Weighted Average with LINQ

    - by jsmith
    My goal is to get a weighted average from one table, based on another tables primary key. Example Data: Table1 Key WEIGHTED_AVERAGE 0200 0 Table2 ForeignKey LENGTH PCR 0200 105 52 0200 105 60 0200 105 54 0200 105 -1 0200 47 55 I need to get a weighted average based on the length of a segment and I need to ignore values of -1. I know how to do this in SQL, but my goal is to do this in LINQ. It looks something like this in SQL: SELECT Sum(t2.PCR*t2.LENGTH)/Sum(t2.LENGTH) AS WEIGHTED_AVERAGE FROM Table1 t1, Table2 t2 WHERE t2.PCR <> -1 AND t2.ForeinKey = t1.Key; I am still pretty new to LINQ, and having a hard time figuring out how I would translate this. The result weighted average should come out to roughly 55.3. Thank you.

  • Group by/count in LINQ against SQL Compact 3.5 SP2

    - by bash74
    Hello, I am using LINQ-To-Entities in C# and run queries against a SQL Compact Server 3.5 SP2. What I try to achieve is a simple group by with an additional where clause which includes a Count(). var baseIdent="expression"; var found=from o in ObservedElements where o.ObservedRoots.BaseIdent==baseIdent group o by o.ID into grouped where grouped.Count()==1 select new {key=grouped.Key, val=grouped}; foreach(var res in found){ //do something here } This query throws the famous exception "A parameter is not allowed in this location. Ensure that the '@' sign and all other parameters are in a valid location in the SQL statement." When I either omit the where clause OR directly enter the expression "expression" in the query (where o.ObservedRoots.BaseIdent=="expression") everything just works fine. Does anybody know how to solve this? Workaround would also be fine? Thanks in advance, Sebastian

  • Exchange 2003 Public Folder Replica list

    - by Niall
    Hi, I am trying to update a replica list on a Exchange 2003 public folder. I am using the WMI namespace exchange_publicfolder to try and add an Exchange server (using the servers DN) to the AddReplica procedure. Every time I run this I get an invalid parameter as an exception. Below is the code that I am using to do this. WMI.Connect(Server, credentials) Using WMISearcher As New ManagementObjectSearcher(WMI.Scope, & _ New ObjectQuery(String.Format("SELECT * FROM Exchange_Publicfolder WHERE path='{0}'", Name))) Using PublicFolder As ManagementObjectCollection = WMISearcher.Get For Each Folder As ManagementObject In PublicFolder Dim BaseFolder As ManagementBaseObject = Folder.GetMethodParameters("AddReplica") BaseFolder("path") = ServerDN Folder.InvokeMethod("AddReplica", BaseFolder, Nothing) Next End Using End Using I have used WMI before and I can see that the call is connecting to the correct public folder because i can itterate through the properies once the query has executed. I am not sure what I am doing wrong here. If anyone has any ideas or comments the please let me know. Thanks Niall

  • MVC3 Razor DropDownListFor Enums

    - by jordan.baucke
    Trying to get my project updated to MVC3, something I just can't find: I have a simple datatype of ENUMS: public enum States() { AL,AK,AZ,...WY } Which I want to use as a DropDown/SelectList in my view of a model that contains this datatype: public class FormModel() { public States State {get; set;} } Pretty straight forward: when I go to use the auto-generate view for this partial class, it ignores this type. I need a simple select list that sets the value of the enum as the selected item when I hit submit and process via my AJAX - JSON POST Method. And than the view (???!): <div class="editor-field"> @Html.DropDownListFor(model => model.State, model => model.States) </div> thanks in advance for the advice!

  • Optimal preferences for prefix queries with Oracle catalog (CTXCAT) index

    - by nw
    The documentation for Oracle Text gives this example of a prefix/substring preference setting for context and catalog indexes: begin ctx_ddl.create_preference('mywordlist', 'BASIC_WORDLIST'); ctx_ddl.set_attribute('mywordlist','PREFIX_INDEX','TRUE'); ctx_ddl.set_attribute('mywordlist','PREFIX_MIN_LENGTH', '3'); ctx_ddl.set_attribute('mywordlist','PREFIX_MAX_LENGTH', '4'); ctx_ddl.set_attribute('mywordlist','SUBSTRING_INDEX', 'YES'); end; What I need to know is whether the substring_index attribute is necessary if I only ever issue prefix searches, such as: SELECT title FROM auction WHERE CATSEARCH(title, 'cam*', '') > 0; TITLE --------------- CANON CAMERA FUJI CAMERA NIKON CAMERA OLYMPUS CAMERA PENTAX CAMERA SONY CAMERA 6 rows selected

  • where do I submit the ipad apps?

    - by Mike
    I read Apple is allowing developers to submit iPad apps for the great opening of the ipad store, but I cannot find anything in my account that says that or allows sending the apps. Another thing is: in order for an app to be accepted you have to sign it with your own certificate but to do that you have to select the device on Xcode. As far as I know, Xcode do not signs with certificates applications that run on the simulator. Beyond that, any try to build a distribution package on Xcode shows messages like "you should disable armv6", and others. So, I ask. Is this news true? If yes, how to I manage to have the app ready for iPad and ready for submission? thanks.

  • jquery sortable problem with ie

    - by corroded
    i am using jquery to sort my lists and i have run into a dead end. First, I checked the jquery site if theirs work on ie7, thats great, it does. next, i checked mine without the styles(so there possibly wont be anything that's intercepting or affecting jquery stuff). but i still get this weird error in ie7 when you sort items in the inner list(i have nested lists) they overlap each other, destroying the layout. if you sort the contianer lists, they work fine! here's a jsfiddle of what i mean: http://jsfiddle.net/GDUpa/ note that if you drag demonstration one or two spots(in ie), it will overlap with the other links. BUT if you drag POC (it will select the whole thing including the links under it), it works fine! is something wrong with my markup?

  • How do I set up derby in eclipse on Ubuntu?

    - by Everett
    The question basically says it all. I'm trying setup up JavaDB on my virtualbox running Ubuntu 9.10. I have the package downloaded and installed through the package manager, which I believe is the right to go about it. I have also installed the Eclipse's Data Platform Tools. I've been following this tutorial here: http://www.vogella.de/articles/EclipseDataToolsPlatform/article.html. I'm stuck at the driver definition step. When I select the driver template from the Name/Type tab and the jar file in the Jar List tab, the OK button is never enabled. At the top of the New Driver Definition dialog it says 'Unable to locate Jar/zip in the file system as specified by the driver definition: derby.jar.' I assume this is the problem. Any help or links to a better tutorial would be much appreciated.

  • Best practices for querying an entire row in a database table? (MySQL / CodeIgniter)

    - by Walker
    Sorry for the novice question! I have a table called cities in which I have fields called id, name, xpos, ypos. I'm trying to use the data from each row to set a div's position and name. What I'm wondering is what's the best practice for dynamically querying an unknown amount of rows (I don't know how many cities there might be, I want to pull the information from all of them) and then passing the variables from the model into the view and then setting attributes with it? Right now I've 'hacked' a solution where I run a different function each time which pulls a value using a query ('SELECT id FROM cities;'), then I store that in a global array variable and pass it into view. I do this for each var so I have arrays called: city_idVar, city_nameVar, city_xposVar, city_yposVar then I know that the city_nameVar[0] matches up with city_xposVar[0] etc. Is there a better way?

  • Using DateDiff in Entity Framwork on a SQL CE database

    I have a method which should return a list of anonymous objects with a calculated column like this: var tomorrow = DateTime.Today.AddDays(1); return from t in this.Events where (t.StartTime >= DateTime.Today && t.StartTime < tomorrow && t.EndTime.HasValue) select new { Client = t.Activity.Project.Customer.Name, Project = t.Activity.Project.Name, Task = t.Activity.Task.Name, Rate = t.Activity.Rate.Name, StartTime = t.StartTime, EndTime = t.EndTime.Value, Hours = (System.Data.Objects.SqlClient.SqlFunctions.DateDiff("m", t.StartTime, t.EndTime.Value) / 60), Description = t.Activity.Description }; Unfortunately I get the following error from the DateDiff function: The specified method 'System.Nullable1[System.Int32] DateDiff(System.String, System.Nullable1[System.DateTime], System.Nullable`1[System.DateTime])' on the type 'System.Data.Objects.SqlClient.SqlFunctions' cannot be translated into a LINQ to Entities store expression. Any ideas what I could have done wrong here? EDIT: I also tried the EntityFunctions class mentioned here, but that did not work as well.

  • Procedure or function expects parameter which was not supplied

    - by eftpotrm
    Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.) C#: SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn); l_oCmd.Parameters.Add(new SqlParameter("@test", SqlDbType.NVarChar)); l_oCmd.Parameters[0].Value = "hello world"; SqlDataAdapter da = new SqlDataAdapter(l_oCmd); da.Fill(l_oPage); SQL: create procedure usp_test ( @test nvarchar(1000) ) as select @test What have I missed?

  • How can I determine if jquery tab is shown because of user click or from tab rotation

    - by Richard Edwards
    I've been using the jQuery UI tabs for a bit now and an interesting request has come up. The current tab setup is using the rotation feature. I need to find a way to determine if the tab is shown because of the result of the rotation itself, or because a user physically clicked the tab. I've wired up all of the standard events, show and select and they fire regardless of the source of the tab change. Does anyone have any ideas? Basically I'd like to do something additional if the user clicked the tab, but not if the tab changes by itself via the rotation. If I wire up the click even to the tabs themselves it doesn't seem to get fired at all, I'm assuming because the tabs widget is using that event itself.

  • Drupal 6: Taxonomy splot up in managed fields?

    - by Ardi Coetzee
    So you have two taxonomies, namely: "Business Type" and "Location" This is assigned to a node called BUSINESS. In effect, when the user creates a BUSINESS node, her has to choose for example, location "New York" and type "Information Services". My problem is when: a) Capturing the taxonomy, and b) Displaying the taxonomy I want the two terms to be separated from each other. I.e. I want to be able to move the two terms individual positions in the MANAGE FIELDS view, so that they can be grouped or placed seperately. Currently, Drupal only allows one entry, called "TAXONOMY" which is effectively the two terms next to each other. This is what I have: This is what I want: Bare in mind, I need to be able to use this with Hierarchical Select, which means Content Taxonomy is not an option.

    I don't have access to a multi-socketed computer, so I am unsure if the following will get the grand total of processors and logical processors. I assume ManagementObjectSearcher will return an instance for each socketed CPU and I just keep a running total? int totalCPUs = 0; int totalLogicalCPUs = 0; ManagementObjectSearcher mos = new ManagementObjectSearcher("Select * from Win32_ComputerSystem"); foreach (var mo in mos.Get()) { string num = mo.Properties["NumberOfProcessors"].Value.ToString(); totalCPUs += Convert.ToInt32(num); num = mo.Properties["NumberOfLogicalProcessors"].Value.ToString(); totalLogicalCPUs += Convert.ToInt32(num); }
