  • Bind a users role to dropdown?

    - by Dynde
    Hi... I'm trying to bind a selected user's role to a dropdown-list. The purpose of this is to be able to change said user's role. I'm attempting this inside a formview hooked up to a linqdatasource which contains a row from the aspnet_User table. The dropdown list is hooked up to a linqdatasource of all the roles in the aspnet_Roles table (with DataValueField="RoleID", DataTextField="RoleName"). I figured it would be possible with something like: SelectedValue='<%# Bind("aspnet_UsersInRole[0].aspnet_Role.RoleID") %>' But this throws a parser exception, about the bind call not being correctly formatted. The roles are there, they show up when I remove the "SelectedValue" Can anyone point me in the right direction?

  • DataGrid giving error and getting invisible whenever some elements visibility is changed

    - by Tarun
    I have a datagrid in which i have textblocks as one column.Then in the next column i have progress bar over which there is a textblock.On loading row of datagrid,i add these three into lists of textblock and progressbar.I start the first progress bar and after 15-20 minutes next progress bar is started.The next progress bar is getting started fine and after 20 minutes it is getting invisible.The problem is that if i try to make textblock invisible,then the whole Datagrid gets invisible and stops working.After all the tasks in the Datagrid are complete i need to make DataGrid invisible and also when i try to do so,the grid becomes invisible and no other event gets fired.... e.g List txtlist=new List(); i=1; txtlist[i].Visibility=Visibility.Collapsed;

  • How to prevent GetOleDbSchemaTable from returning duplicate sheet names from Excel workbook

    - by Richard Bysouth
    Hi I have a function to return a DataView containing info on sheets in an Excel Workbook, as follows: Public Function GetSchemaInfo() As DataView Using connection As New OleDbConnection(GetConnectionString()) connection.Open() Dim schemaTable As DataTable = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, Nothing) connection.Close() Return New DataView(schemaTable) End Using End Function This works fine except that if the workbook has linked data (i.e. pulls its data from another workbook), duplicate sheet names are returned. For example, Workbook1 has a single worksheet, Sheet1. I get 2 rows in the DataView, with the TABLE_NAME field being "Sheet1$" and "Sheet1$_". OK, I could use a RowFilter, but wondered whether there was a better way or why this extra row is returned? thanks Richard

  • ASP.NET GridView and UpdatePanel

    - by Echilon
    I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.

  • Log to rolling CSV file with Enterprise Library

    - by Tinminator
    Need logging to: Rolling file, to avoid 1 big log file. CSV format for easier look up. I can see EntLib (5.0) have Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener to log to rolling log file. To make the log entries look like a CSV row, I can change the Logging.Formatters.TextFormatter.Template to put double quote around the values. Also change the Listener's Footer and Header to nothing, so they won't be output. Under normal circumstance, this would give me a well formed CSV file. However if a token value in the Template contain double quote, this would not be escaped, hence the log file become an invalid CSV file. Is there any way to resolve this? Is there any alternative solutions to this problem?

  • Changing SQL Server Database sorting

    - by plaisthos
    I have a request to change the collation of a SQL Server Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig.

Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

  • Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

    - by user1656286
    I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.

  • help, php calendar links

    - by Ray
    Below is a partial table row that will create a line row of 3 columns. Two columns in each side is links, left is previous year and right is next year links. Center is links for january thru december. When you click a month links, the calendar will show that month you've clicked in the current year the calendar is on. For example, the calendar will open current month and year by default...March 2010. If you clicked previous year (2009), it will display current month (March) of last year (2009)...and then if you click Jun, the calendar will display June of whatever the year the calendar is currently on, which is June of 2009. my question is, what can i do to following code to do such thing. $Calendar.= "</tr><tr><td>"."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=" . $LastYear["year"] ."\"> $LastY </a></td>\n"; $Calendar.= "<td colspan=\"5\">"."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[0] ."\">Jan.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[1] ."\">Feb.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[2] ."\">Mar.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[3] ."\">Apr.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[4] ."\">May</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[5] ."\">Jun.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[6] ."\">Jul.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[7] ."\">Aug.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[8] ."\">Sep.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[9] ."\">Oct.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[10] ."\">Nov.</a> | "."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=".$ThisYear["year"]."&month=" . $MonthArray[11] ."\">Dec.</a> </td>"; $Calendar.= "<td>"."<a "."href=\"".$_SERVER["PHP_SELF"]."?year=" . $NextYear["year"] ."\"> $NextY </a></td>\n"; Thanks in advance.

  • How to manage a large dataset using Spring MySQL and RowCallbackHandler

    - by rmarimon
    I'm trying to go over each row of a table in MySQL using Spring and a JdbcTemplate. If I'm not mistaken this should be as simple as: JdbcTemplate template = new JdbcTemplate(datasource); template.setFetchSize(1); // template.setFetchSize(Integer.MIN_VALUE) does not work either template.query("SELECT * FROM cdr", new RowCallbackHandler() { public void processRow(ResultSet rs) throws SQLException { System.out.println(rs.getString("src")); } }); I get an OutOfMemoryError because it is trying to read the whole thing. Any ideas?

  • Displaying rows in multiple columns

    - by zizo
    Not sure if this is doable using sql alone or not, but here is the problem. I have a weird requirement that data needs to be displayed in columns so users can compare data quickly! Here is what the result set looks like right now CustomerID Company Active 001 ATT Y 002 ATT N 003 ATT Y 001 VZ Y 002 VZ N 003 VZ Y 001 TM Y 002 TM Y 003 TM Y Now this is how they want to see it CustomerID Company Active Company Active Company Active 001 ATT Y VZ Y TM Y 002 ATT N VZ N TM Y 003 ATT Y VZ Y TM Y Assumptions: This could be a pretty long table, that's why they want to see all companies on one row, rather than needing to scroll down to see if active or not. Nummber of companies is between 1-3 in most cases Any help is appreciated. Thanks!

  • Get In That DB! Parsing CSV Using Ruby...

    - by keruilin
    I have a CSV file formatted just like this: name,color,tasty,qty apple,red,true,3 orange,orange,false,4 pear,greenish-yellowish,true,1 As you can see, each column in the Ruby OO world represents a mix of types -- string, string, boolean, int. Now, ultimately, I want to parse each line in the file, determine the appropriate type, and insert that row into a database via a Rails migration. For ex: Fruit.create(:name => 'apple', :color => 'red', :tasty => true, :qty => 3) Help!

  • What would the conditional statement be to filter these inputs?

    - by dmanexe
    I have a page with a form, and on the form are a bunch of input check boxes. In the following page, there's the following code to process the inputs from the page before (which are set as an ID). <? $field = $this->input->post('measure',true); $totals = array(); foreach($field as $value): $query = $this->db->get_where('items', array('id' => $value['input']))->row(); $totals[] = $query->price; ?> #HTML for displaying estimate output here <?php endforeach; ?> How would I have the loop run conditionally only if there was a check on the input on the page before?

  • how to precompile a jquery ui autocomplete widget?

    - by Alex
    Hello, I have a jquery ui autocomplete widget in a form and I'd like to preselect its value from a database. My autocomplete works in the following way: the id is a number, tha label and the value are the same and are a concatenation of id + " - " + description. When a value from the autocomplete is selected, a hidden field's value is set to the value of id. Then, the hidden field value is saved to the db when the form is submitted. When the user comes back on the page for editing, I need to reload the value from the db: I set the idden field value again and then I would like to precompile the value of the autocomplete widget with the concatenation of id + " - " + description taken form the db. I think I should trigger the event of selecting a row in the autocomplete, but I don't know how to do. Do you have any ideas? Thank you Here is the code of the autocomplete: $('#codice_contratto').autocomplete({ source: 'do_contratto.php', select: function(event, ui) { $('#id_contratto').val(ui.item.id); } });

Sorting arrows dont appear but are clickable, and filters are wildy off. Whats causing this. I deleted everything in the .css file. GWT newbie here.

  • iPhone: Using plist to populate a grouped table

    - by Jack Griffiths
    Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

  • One table, need multiple values from different rows/tuples

    - by WmasterJ
    I have tables like: 'profile_values' userID | fid | value -------+---------+------- 1 | 3 | [email protected] 1 | 45 | 203-234-2345 3 | 3 | [email protected] 1 | 45 | 123-456-7890 And: 'users' userID | name -------+------- 1 | joe 2 | jane 3 | jake I want to join them and have one row with two of the values like: 'profile_values' userID | name | email | phone -------+-------+----------------+-------------- 1 | joe | [email protected] | 203-234-2345 2 | jane | [email protected] | 123-456-7890 I have solved it but it feels clumsy and I want to know if there is a better way to do it. Meaning solutions that are either more readable or faster(optimized) or simply best-practice. Current solution: multiple tables selected, many conditional statements: SELECT u.userID AS memberid, u.name AS first_name, pv1.value AS fname, pv2.value as lname FROM users AS u, profile_values AS pv1, profile_values AS pv2, WHERE u.userID = pv1.userID AND pv1.fid = 3 AND u.userID = pv2.userID AND pv2.fid = 45; Thanks for the help!

  • Which cross threading invoke function is better for a control that is inherited?

    - by Stevoni
    I have a relatively simple question regarding the best way to call the DataGridView.Rows.Add function when it is inherited into the current control. Which is the best way to make the call to the inherited control? Call it directly in the invoke or call it using recursive-like function? They both seem to produce the same result, a row gets added and the quantity is returned, but which is the most efficient? The delegate: Private Delegate Function ReturnDelegate() As Object The two ways are: A) Private Overloads Function AddRow() As Integer If InvokeRequired Then Return CInt(Invoke(New ReturnDelegate(AddressOf AddRow))) Else Return Rows.Add() End If End Function Or B) Private Function RowsAdd() As Integer If Me.InvokeRequired Then Return CInt(Me.Invoke(New ReturnDelegate(AddressOf MyBase.Rows.Add))) Else Return MyBase.Rows.Add End If End Function

  • JPA and MySQL transaction isolation level

    - by armandino
    I have a native query that does a batch insert into a MySQL database: String sql = "insert into t1 (a, b) select x, y from t2 where x = 'foo'"; EntityTransaction tx = entityManager.getTransaction(); try { tx.begin(); int rowCount = entityManager.createNativeQuery(sql).executeUpdate(); tx.commit(); return rowCount; } catch(Exception ex) { tx.rollback(); log.error(...); } This query causes a deadlock: while it reads from t2 with insert .. select, another process tries to insert a row into t2. I don't care about the consistency of reads from t2 when doing an insert .. select and want to set the transaction isolation level to READ_UNCOMMITTED. How do I go about setting it in JPA?

  • Unable to specify abstract classes in TPH hierarchy in Entity Framework 4

    - by Lee Atkinson
    Hi I have a TPH heirachy along the lines of: A-B-C-D A-B-C-E A-F-G-H A-F-G-I I have A as Abstract, and all the other classes are concrete with a single discriminator column. This works fine, but I want C and G to be abstract also. If I do that, and remove their discriminators from the mapping, I get error 3034 'Two entities with different keys are mapped to the same row'. I cannot see how this statement can be correct, so I assume it's a bug in some way. Is it possible to do the above? Lee

  • Fixtures and inheritance in Symfony

    - by Tere
    Hi! I have a database schema in Symfony like this: Persona: actAs: { Timestampable: ~ } columns: primer_nombre: { type: string(255), notnull: true } segundo_nombre: { type: string(255) } apellido: { type: string(255), notnull: true } rut: { type: string(255) } email: { type: string(255) } email2: { type: string(255) } direccion: { type: string(400) } ciudad: { type: string(255) } region: { type: string(255) } pais: { type: string(255) } telefono: { type: string(255) } telefono2: { type: string(255) } fecha_nacimiento: { type: date } Alumno: inheritance: type: concrete extends: Persona columns: comentario: { type: string(255) } estado_pago: { type: string(255) } Alumno_Beca: columns: persona_id: { type: integer, primary: true } beca_id: { type: integer, primary: true } relations: Alumno: { onDelete: CASCADE, local: persona_id, foreign: id } Beca: { onDelete: CASCADE, local: beca_id, foreign: id } Beca: columns: nombre: { type: string(255) } monto: { type: double } porcentaje: { type: double } descripcion: { type: string(5000) } As you see, "alumno" has a concrete inheritance from "persona". Now I'm trying to create fixtures for this two tables, and I can't make Doctrine to load them. It gives me this error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (eat/alumno__beca, CONSTRAINT alumno__beca_persona_id_alumno_id FOREIGN KEY (persona_id) REFERENCES alumno (id) ON DELETE CASCADE) Does someone know how to write a fixture for a table inherited from another? Thanks!

  • Push a ViewController and It Pops Right Back

    - by Jim Bonner
    I have a view controller with a table view and a UISearchBar. When the view controller is first brought up, the table is populated. A click on a table row pushes another view controller, it animates up and then pops right back down and returns me to the table. It does this whether the search bar has been used or not. I do this push pop kind of action in several view controllers with not problem. My guess is that the UISearchBar is somehow getting in the way. Any one have any idea as to what I'm doing wrong?

  • How to Remove the Last Week Of a Calendar

    - by Nassign
    I am not sure why other people have not asked this before. But have you notice that the asp:Calendar shows an extra week at the end? For example if the VisibleMonth is set to 2010-03-01 and FirstDayOfWeek to Sunday: It will show 6 weeks. Feb 28 to March 6 March 7 to March 13 March 14 to March 20 March 21 to March 27 March 28 to April 3 April 4 to April 10 I was wondering why Microsoft shows the last Row which is entirely on April. I tried to search the net for a property but it does not seem to be existing. The only solution that I could think of is to override the Pre_Render and check all individual date if they are still within the week of the VisibleDate. But of course that is an extreme checking since each rendering of the control shows it.

  • SQL Server version of MySQL's group_concat and escaped strings

    - by TheObserver
    I only have the Express versions of MS SQL Server 2008 and Visual Studio. Given that I can't create a SQL Server project and therefore CLR solutions are out of the question, I've attempted to use select col1, stuff( ( select ' ' + col2 from StrConcat t1 where t2.col1 = t1.col1 for xml path('') ),1,1,'') from StrConcat t2 group by col1 order by col1 to get a row concatenated col2. col2 is a varchar field with some control characters like & and \n. When it is concatenated with the above SQL, it appears to escape those control characters ie. & becomes & amp ; and \n becomes &#xOD, which is not what I want it to do. So, the question is, what black box magic is causing that to happen?
