• Toolbar hiding on rotated UISplitView DetailView

  - by Gerry

  I've based my app on Apple's SplitView project type. I have a TableView as the Master, and am using different types of views as the Detail view. To select types of detail view, I'm using the fancy concept of buttons on my DetailView toolbar. When the DetailView is derived from UIViewController, everything is good. When the DetailView derives from UIViewController, but contains a UITableView then I have problems. In portrait view the toolbar is visible. In landscape mode the toolbar is hidden, even though the Tableview is moved down to allow space for it. The UIToolbar and UITableView are both defined in my NIB file which is loaded to create the detail view. Why is my toolbar invisible in landscape? BTW, is this the best way to choose Detail view types with UISplitView? Bonus question, what if selecting a row in my DetailView tableview should bring up another View, I can't push it like I would with a NaviagtionController, so how do I go back to the detail tableview? Thanks, Gerry

• C# Problem with getPixel & setting RTF text colour accordingly

  - by m3n

  Heyo, I'm messing with converting images to ASCII ones. For this I load the image, use getPixel() on each pixel, then change insert a character with that colour into a richTextBox. Bitmap bmBild = new Bitmap(openFileDialog1.FileName.ToString()); // valid image int x = 0, y = 0; for (int i = 0; i <= (bmBild.Width * bmBild.Height - bmBild.Height); i++) { // Ändra text här richTextBox1.Text += "x"; richTextBox1.Select(i, 1); if (bmBild.GetPixel(x, y).IsKnownColor) { richTextBox1.SelectionColor = bmBild.GetPixel(x, y); } else { richTextBox1.SelectionColor = Color.Red; } if (x >= (bmBild.Width -1)) { x = 0; y++; richTextBox1.Text += "\n"; } x++; } GetPixel does return the correct colour, but the text only end up black. If I change this richTextBox1.SelectionColor = bmBild.GetPixel(x, y); to this richTextBox1.SelectionColor = Color.Red; It works fine. Why am I not getting the right colours? (I know it doesn't do the new lines properly, but I thought I'd get to the bottom of this issue first.) Thanks

• How can I turn a column name into a result value in SQL Server?

  - by Brennan

  I have a table which has essentially boolean values in a legacy database. The column names are stored as string values in another table so I need to match the column names of one table to a string value in another table. I know there has to be a way to do this directly with SQL in SQL Server but it is beyond me. My initial thought was to use PIVOT but it is not enabled by default and enabling it would likely be a difficult process with pushing that change to the Production database. I would prefer to use what is enabled by default. I am considering using COALESCE to translate the boolean value to the string that value that I need. This will be a manual process. I think I will also use a table variable to insert the results of the first query into that variable and use those results to do the second query. I still have the problem that the columns are on a single row so I wish I could easily pivot the values to put the column names in the result set as strings. But if I could easily do that I could easily write the query with a sub-select. Any tips are welcome.

• Guaranteed way to find the ildasm.exe and ilasm.exe files regardless of .NET version/environment?

  - by m-y

  Is there a way to programmatically get the FileInfo/Path of the ildasm.exe/ilasm.exe executables? I'm attempting to decompile and recompile a dll/exe file appropriately after making some alterations to it (I'm guessing PostSharp does something similar to alter the IL after the compilation). I found a blog post that pointed to: var pfDir = Environment.GetFolderPath(Environment.SpecialFolders.ProgramFiles)); var sdkDir = Path.Combine(pfDir, @"Microsoft SDKs\Windows\v6.0A\bin"); ... However, when I ran this code the directory did not exist (mainly because my SDK version is 7.1), so on my local machine the correct path is @"Microsoft SDKs\Windows\v7.1\bin". How do I ensure I can actually find the ildasm.exe? Similarly, I found another blog post on how to get access to ilasm.exe as: string windows = Environment.GetFolderPath(Environment.SpecialFolder.System); string fwork = Path.Combine(windows, @"..\Microsoft.NET\Framework\v2.0.50727"); ... While this works, I noticed that I have Framework and Framework64, and within Framework itself I have all of the versions up to v4.0.30319 (same with Framework64). So, how do I know which one to use? Should it be based on the .NET Framework version I'm targetting? Summary: How do I appropriately guarantee to find the correct path to ildasm.exe? How do I appropriately select the correct ilasm.exe to compile?

• Problem counting item frequency on T-SQL

  - by Raúl Roa

  I'm trying to count the frequency of numbers from 1 to 100 on different fields of a table. Let's say I have the table "Results" with the following data: LottoId Winner Second Third --------- --------- --------- --------- 1 1 2 3 2 1 2 3 I'd like to be able to get the frequency per numbers. For that I'm using the following code: --Creating numbers temp table CREATE TABLE #Numbers( Number int) --Inserting the numbers into the temp table declare @counter int set @counter = 0 while @counter < 100 begin set @counter = @counter + 1 INSERT INTO #Numbers(Number) VALUES(@counter) end -- SELECT #Numbers.Number, Count(Results.Winner) as Winner,Count(Results.Second) as Second, Count(Results.Third) as Third FROM #Numbers LEFT JOIN Results ON #Numbers.Number = Results.Winner OR #Numbers.Number = Results.Second OR #Numbers.Number = Results.Third GROUP BY #Numbers.Number The problem is that the counts are repeating the same values for each number. In this particular case I'm getting the following result: Number Winner Second Third --------- --------- --------- --------- 1 2 2 2 2 2 2 2 3 2 2 2 ... When I should get this: Number Winner Second Third --------- --------- --------- --------- 1 2 0 0 2 0 2 0 3 0 0 2 ... What am I missing?

• How to code a URL shortener?

  - by marco92w

  I want to create a URL shortener service where you can write a long URL into an input field and the service shortens the URL to "http://www.example.org/abcdef". Instead of "abcdef" there can be any other string with six characters containing a-z, A-Z and 0-9. That makes 56 trillion possible strings. My approach: I have a database table with three columns: id, integer, auto-increment long, string, the long URL the user entered short, string, the shortened URL (or just the six characters) I would then insert the long URL into the table. Then I would select the auto-increment value for "id" and build a hash of it. This hash should then be inserted as "short". But what sort of hash should I build? Hash algorithms like MD5 create too long strings. I don't use these algorithms, I think. A self-built algorithm will work, too. My idea: For "http://www.google.de/" I get the auto-increment id 239472. Then I do the following steps: short = ''; if divisible by 2, add "a"+the result to short if divisible by 3, add "b"+the result to short ... until I have divisors for a-z and A-Z. That could be repeated until the number isn't divisible any more. Do you think this is a good approach? Do you have a better idea?

• SHA function issues

  - by Damian James

  I have this php code from my login.php if (isset($_POST['logIn'])) { $errmsg = ""; $logname = mysqli_real_escape_string($dbc, trim($_POST['usernameIn'])); $logpassword = mysqli_real_escape_string($dbc, trim($_POST['passwordIn'])); $query = "SELECT user_id, username FROM members WHERE username = '$logname' AND password = SHA('$logpassword')"; $data = mysqli_query($dbc, $query); if (mysqli_num_rows($data) == 1) { $row = mysqli_fetch_array($data); setcookie('user_id', $row['user_id'], time() + (60 * 60 * 24 * 30)); //expires after 30 days setcookie('username', $row['username'], time() + (60 * 60 * 24 * 30)); $home = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php'; header('Location: ' . $home); } else { $errmsg = '<p class="errormsg">Username or password is incorrect.</p>'; } } And for some reason, it always ends up setting $errmsg in the else statement. I am sure that I'm entering information (username,password) that is correct and exists in the database. I insert my values (from a signup script) using this query: $query = "INSERT INTO members (username, password, email) VALUES ('$username', SHA('$password'), '$email')"; Anyone see the problem with this script? Thanks!

• Automation Error upon running VBA script in Excel

  - by brohjoe

  Hi guys, I'm getting an Automation error upon running VBA code in Excel 2007. I'm attempting to connect to a remote SQL Server DB and load data to from Excel to SQL Server. The error I get is, "Run-time error '-2147217843(80040e4d)': Automation error". I checked out the MSDN site and it suggested that this may be due to a bug associated with the sqloledb provider and one way to mitigate this is to use ODBC. Well I changed the connection string to reflect ODBC provider and associated parameters and I'm still getting the same error. Here is the code with ODBC as the provider: Dim cnt As ADODB.Connection Dim rst As ADODB.Recordset Dim stSQL As String Dim wbBook As Workbook Dim wsSheet As Worksheet Dim rnStart As Range Public Sub loadData() 'This was set up using Microsoft ActiveX Data Components version 6.0.

• SQL Server CLR stored procedures in data processing tasks - good or evil?

  - by Gart

  In short - is it a good design solution to implement most of the business logic in CLR stored procedures? I have read much about them recently but I can't figure out when they should be used, what are the best practices, are they good enough or not. For example, my business application needs to parse a large fixed-length text file, extract some numbers from each line in the file, according to these numbers apply some complex business rules (involving regex matching, pattern matching against data from many tables in the database and such), and as a result of this calculation update records in the database. There is also a GUI for the user to select the file, view the results, etc. This application seems to be a good candidate to implement the classic 3-tier architecture: the Data Layer, the Logic Layer, and the GUI layer. The Data Layer would access the database The Logic Layer would run as a WCF service and implement the business rules, interacting with the Data Layer The GUI Layer would be a means of communication between the Logic Layer and the User. Now, thinking of this design, I can see that most of the business rules may be implemented in a SQL CLR and stored in SQL Server. I might store all my raw data in the database, run the processing there, and get the results. I see some advantages and disadvantages of this solution: Pros: The business logic runs close to the data, meaning less network traffic. Process all data at once, possibly utilizing parallelizm and optimal execution plan. Cons: Scattering of the business logic: some part is here, some part is there. Questionable design solution, may encounter unknown problems. Difficult to implement a progress indicator for the processing task. I would like to hear all your opinions about SQL CLR. Does anybody use it in production? Are there any problems with such design? Is it a good thing?

• Python win32com - Automating Word - How to replace text in a text box?

  - by Greg

  I'm trying to automate word to replace text in a word document using Python. (I'm on word 2003 if that matters and Python 2.4) The first part of my replace method below works on everything except text in text boxes. The text just doesn't get selected. I notice when I go into Word manually and hit ctrl-A all of the text gets selected except for the text box. Here's my code so far: class Word: def __init__(self,visible=0,screenupdating=0): pythoncom.CoInitialize() self.app=gencache.EnsureDispatch(WORD) self.app.Visible = visible self.app.DisplayAlerts = 0 self.app.ScreenUpdating = screenupdating print 'Starting word' def open(self,doc): self.opendoc=os.path.basename(doc) self.app.Documents.Open(FileName=doc) def replace(self,source,target): if target=='':target=' ' alltext=self.app.Documents(self.opendoc).Range(Start=0,End=self.app.Documents(self.opendoc).Characters.Count) #select all alltext.Find.Text = source alltext.Find.Replacement.Text = target alltext.Find.Execute(Replace=1,Forward=True) #Special handling to do replace in text boxes #http://word.tips.net/Pages/T003879_Updating_a_Field_in_a_Text_Box.html for shp in self.app.Documents(self.opendoc).Shapes: if shp.TextFrame.HasText: shp.TextFrame.TextRange.Find.Text = source shp.TextFrame.TextRange.Find.Replacement.Text = target shp.TextFrame.TextRange.Find.Execute(Replace=1,Forward=True) #My Usage word=Word(visible=1,screenupdating=1) word.open(r'C:\Invoice Automation\testTB.doc') word.replace('[PGN]','1') The for shp in self.app .. section is my attempt to hit the text boxes. It seems to find the text box, but it doesn't replace anything.

• Dynamic SQL To Dynamic LINQ in VB.NET with MS SQL Server 2008

  - by user337501

  I dread asking this question, because with what I've read so far I understand im gonna have to cram a lotta new things into my head. In spite of all the similiar questions(and the wide variety of answers) I thought I'd ask as nothing I've read tailors to what I need specifically enough. I need to represent the following query using LINQ: DECLARE @PurchasedInventoryItemID Int = 2 DECLARE @PurchasedInventorySectionID Int = 0 DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3 DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0 DECLARE @IsActive Bit = 1 DECLARE @PropertyID Int = 2 DECLARE @PropertyValue nvarchar(1000) = 'Granny Smith' --Property1, Property2, Property3 ... SELECT O.PurchasedInventoryObjectID, O.PurchasedInventoryObjectName, O.PurchasedInventoryConjunctionID, O.Summary, O.Count, O.PropertyCount, O.IsActive FROM tblPurchasedInventoryObject As O INNER JOIN tblPurchasedInventoryConjunction As C ON C.PurchasedInventoryConjunctionID = O.PurchasedInventoryConjunctionID INNER JOIN tblPurchasedInventoryItem As I ON I.PurchasedInventoryItemID = C.PurchasedInventoryItemID INNER JOIN tblPurchasedInventorySection As S ON S.PurchasedInventorySectionID = C.PurchasedInventorySectionID INNER JOIN tblPurchasedInventoryPropertyMap as M ON M.PurchasedInventoryObjectID = O.PurchasedInventoryObjectID INNER JOIN tblPropertyValue As V ON V.PropertyValueID = M.PropertyValueID WHERE I.PurchasedInventoryItemID = @PurchasedInventoryItemID AND S.PurchasedInventorySectionID = @PurchasedInventorySectionID AND I.PurchasingCategoryID = @PurchasedInventoryItem_PurchasingCategoryID AND S.PurchasingCategoryID = @PurchasedInventorySection_PurchasingCategoryID AND O.IsActive = @IsActive AND V.PropertyID = @PropertyID AND V.Value = @PropertyValue Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables. My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times. In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions. I can also make a Stored Procedure in MS SQL, which is easy enough. However, I want to accomplish this using LINQ. If anyone could direct me, I would be most appreciative.

• Linq to SQL case sensitivity causing problems

  - by Roger Lipscombe

  I've seen this question, but that's asking for case-insensitive comparisons when the database is case-sensitive. I'm having a problem with the exact opposite. I'm using SQL Server 2005, my database collation is set to Latin1_General_CI_AS. I've got a table, "User", like this: CREATE TABLE [dbo].[User] ( [Id] [int] IDENTITY(1,1) NOT NULL, [Name] [nvarchar](max) NOT NULL, CONSTRAINT [PK_Example] PRIMARY KEY CLUSTERED ( [Id] ASC ) ) And I'm using the following code to populate it: string[] names = new[] { "Bob", "bob", "BoB" }; using (MyDataContext dataContext = new AppCompatDataContext()) { foreach (var name in names) { string s = name; if (dataContext.Users.SingleOrDefault(u => u.Name == s) == null) dataContext.Users.InsertOnSubmit(new User { Name = name }); } dataContext.SubmitChanges(); } When I run this the first time, I end up with "Bob", "bob" and "BoB" in the table. When I run it again, I get an InvalidOperationException: "Sequence contains more than one element", because the query against the database returns all 3 rows, and... SELECT * FROM [User] WHERE Name = 'bob' ... is case-insensitive. That is: when I'm inserting rows, Linq to SQL appears to use C# case-sensitive comparisons. When I query later, Linq to SQL uses SQL Server case-insensitive comparisons. I'd like the initial insert to use case-insensitive comparisons, but when I change the code as follows... if (dataContext.Users.SingleOrDefault(u => u.Name.Equals(s, StringComparison.InvariantCultureIgnoreCase) ) == null) ... I get a NotSupportedException: "Method 'Boolean Equals(System.String, System.StringComparison)' has no supported translation to SQL." Question: how do I get the initial insert to be case-insensitive or, more precisely, match the collation of the column in the database? Update: This doesn't appear to be my problem. My problem appears to be that SingleOrDefault doesn't actually look at the pending inserts at all.

• What Algorithm will Find New Longtail Keywords for *keyword* in PPC

  - by Becci

  I am looking for the algorithm (or combo) that would allow someone to find new longtail PPC search phrases based on say one corekeyword. Eg #1 word word corekeyword eg #2 word corekeyword word Google search tool allows a limited number vertically - mostly of eg#1 (https://adwords.google.com.au/select/KeywordToolExternal) I also know of other PPC apps that allow more volume than google adwords keyword tool, But I want to find other combos that mention the corekeyword & then naturally sort for the highest volume searched. Working example of exact match: corekeyword: copywriter (40,500 searches a month) google will serve up: become a copywriter (480 searches globally/month in english) But if I specifically look up: How to become a copywriter (720 searches a month) This exact longtail keyword phrase has 300 more searches than the 3 word version spat out by google. I want the algorithm to find any other highly search exact longtials like: how to become a copywriter Simply because it was save significant $ finding other longtail keywords after your campaign has been running an made google lots of money. I don't want a concantenation algorithm (I already have one of those), because hypothetically, I don't know what keywords will be that I want to find. Any gurus out there? Becci

• Zend Framework how to echo value of SUM query

  - by Rick de Graaf

  Hello, I created a query for the zend framework, in which I try to retrieve the sum of a column, in this case the column named 'time'. This is the query I use: $this->timequery = $this->db_tasks->fetchAll($this->db_tasks->select()->from('tasks', 'SUM(time)')->where('projectnumber =' . $this->value_project)); $this->view->sumtime = $this->timequery; Echoing the query tells me this is right. But I can't echo the result properly. Currently I'm using: echo $this->sumtime['SUM(time)']; Returning the following error: Catchable fatal error: Object of class Zend_Db_Table_Row could not be converted to string in C:\xampp\htdocs\BManagement\application\views\scripts\tasks\index.phtml on line 46 Line 46 being the line with the echo in my view. I've been searching now for two days on how to figure this out, or achieve the same result in a different way. Tried to serialize the value, but that didn't work either. Is there somebody who knows how to achieve the total sum of a database column? Any help is greatly appriciated! note: Pretty new to zend framework...

• ASP Classic, SQL 2008, XML Output, and DSN vs DSN-Less Produces Chinese Letters

  - by RoLYroLLs

  I've been having a problem for the past month and can't seem to figure out what is wrong. Here's the setup and a little background. Background: I have a web-host who was running my website on Windows Server 2003 and SQL Server 2000. One of my webpages returned a result set from a stored procedure from the SQL server as xml. Below is the code: Stored Procedure: select top 10 1 as tag , null as parent , column1 as [item!1!column1!element] , column2 as [item!1!column2!element] from table1 for XML EXPLICIT ASP Page: index.asp Call OpenConn Set cmd = Server.CreateObject("ADODB.Command") With cmd .ActiveConnection = dbc .CommandText = "name of proc" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("@RetVal", adInteger, adParamReturnValue, 4) .Parameters.Append .CreateParameter("@Level", adInteger, adParamInput, 4, Level) End With Set rsItems = Server.CreateObject("ADODB.Recordset") With rsItems .CursorLocation = adUseClient .CursorType = adOpenStatic .LockType = adLockBatchOptimistic Set .Source = cmd .Open Set .ActiveConnection = Nothing End With If NOT rsItems.BOF AND NOT rsItems.EOF Then OutputXMLQueryResults rsItems,"items" End If Set rsItems = Nothing Set cmd = Nothing Call CloseConn Sub OpenConn() strConn = "Provider=SQLOLEDB;Data Source=[hidden];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" Set dbc = Server.CreateObject("ADODB.Connection") dbc.open strConn End Sub Sub CloseConn() If IsObject(dbc) Then If dbc.State = adStateOpen Then dbc.Close End If Set dbc = Nothing End If End Sub Sub OutputXMLQueryResults(RS,RootElementName) Response.Clear Response.ContentType = "text/xml" Response.Codepage = 65001 Response.Charset = "utf-8" Response.Write "" Response.Write "" While Not RS.EOF Response.Write RS(0).Value RS.MoveNext WEnd Response.Write "" Response.End End Sub Present: All was working great, until my host upgraded to Windows Server 2008 and SQL Server 2008. All of the sudden I was getting results like this: From Browser: From View Source: However, I found that if I use a DSN connection strConn = "DSN=[my DSN Name];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" it works perfectly fine! My current host is not going to support DSN any longer, but that's out of scope for this issue. Someone told me to use an ADO.Stream object instead of a Recordset object, but I'm unsure how to implement that. Question: Has anyone run into this and found a way to fix it? What about that ADO.Stream object, can someone help me with a sample that would fit my code?

• How to force ADO.Net to use only the System.String DataType in the readers TableSchema.

  - by Keith Sirmons

  Howdy, I am using an OleDbConnection to query an Excel 2007 Spreadsheet. I want force the OleDbDataReader to use only string as the column datatype. The system is looking at the first 8 rows of data and inferring the data type to be Double. The problem is that on row 9 I have a string in that column and the OleDbDataReader is returning a Null value since it could not be cast to a Double. I have used these connection strings: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="ExcelFile.xlsx";Persist Security Info=False;Extended Properties="Excel 12.0;IMEX=1;HDR=No" Provider=Microsoft.Jet.OLEDB.4.0;Data Source="ExcelFile.xlsx";Persist Security Info=False;Extended Properties="Excel 8.0;HDR=No;IMEX=1" Looking at the reader.GetSchemaTable().Rows[7].ItemArray[5], it's dataType is Double. Row 7 in this schema correlates with the specific column in Excel I am having issues with. ItemArray[5] is its DataType column Is it possible to create a custom TableSchema for the reader so when accessing the ExcelFiles, I can treat all cells as text instead of letting the system attempt to infer the datatype? I found some good info at this page: Tips for reading Excel spreadsheets using ADO.NET The main quirk about the ADO.NET interface is how datatypes are handled. (You'll notice I've been carefully avoiding the question of which datatypes are returned when reading the spreadsheet.) Are you ready for this? ADO.NET scans the first 8 rows of data, and based on that guesses the datatype for each column. Then it attempts to coerce all data from that column to that datatype, returning NULL whenever the coercion fails! Thank you, Keith Here is a reduced version of my code: using (OleDbConnection connection = new OleDbConnection(BuildConnectionString(dataMapper).ToString())) { connection.Open(); using (OleDbCommand cmd = new OleDbCommand()) { cmd.Connection = connection; cmd.CommandText = SELECT * from [Sheet1$]; using (OleDbDataReader reader = cmd.ExecuteReader()) { using (DataTable dataTable = new DataTable("TestTable")) { dataTable.Load(reader); base.SourceDataSet.Tables.Add(dataTable); } } } }

• searching article for names in the database before submitting article to the database

  - by zurna

  I want to create a function that will search through a text, find names those match with existing names in the database and add links to those names before submitting the article to the database. i.e. text: Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. Nicolas Anelka exists in the database in the Players table with ID column equals to 1. I want text to be converted to Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately.

• searching article for names in the database before submitting article to the database

  - by zurna

  I want to create a function that will search through a text, find names those match with existing names in the database and add links to those names before submitting the article to the database. i.e. text: Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. Nicolas Anelka exists in the database in the Players table with ID column equals to 1. I want text to be converted to Chelsea are making a change now as goalscorer a href="player.asp=ID=1"Nicolas Anelka/a is replaced by in-form Florent Malouda who can do no wrong lately. I know my code is logically wrong but I could build the correct logic. Function PlayerStats (ArticleDesc) If IsNull(ArticleDesc) Then Exit Function SQL = "SELECT PlayerID, PlayerName" SQL = SQL & " FROM Players" ' SQL = SQL & " WHERE PlayerID = "& &"" Set objPlayer = objConn.Execute(SQL) Do While NOT objPlayer.EOF ArticleDesc = Replace(ArticleDesc, objPlayer("PlayerName"), "!"&objPlayer("PlayerName")&"!") PlayerStats = ArticleDesc Loop objPlayer.MoveNext End Function

• Using nhibernate <loader> element with HQL queries

  - by Matt

  Hi All I'm attempting to use an HQL query in element to load an entity based on other entities. My class is as follows public class ParentOnly { public ParentOnly(){} public virtual int Id { get; set; } public virtual string ParentObjectName { get; set; } } and the mapping looks like this <class name="ParentOnly"> <id name="Id"> <generator class="identity" /> </id> <property name="ParentObjectName" /> <loader query-ref="parentonly"/> </class> <query name="parentonly" > select new ParentOnly() from SimpleParentObject as spo where spo.Id = :id </query> The class that I am attemping to map on top of is SimpleParentObject, which has its own mapping and can be loaded and saved without problems. When I call session.Get(id) the sql runs correctly against the SimpleParentObject table, and the a ParentOnly object is instantiated (as I can step through the constructer), but only a null comes back, rather than the instantiated ParentOnly object. I can do this succesfully using a instead of the HQL, but am trying to build this in a database independent fashion. Any thoughts on how to get the and elements to return a populated ParentOnly object...? Thanks Matt

• Piloting Microsoft Word With Ole in C++ Builder : how to put Word in the foreground.

  - by Getz

  Hi! I've got a code (which works fine) for piloting word with C++ Builder. It's useful for reaching different bookmarks in the document. Variant vNom, vWDocuments, vWDocument, vMSWord, vSignets, vSignet; vNom = WideString("blabla.doc"); try { vMSWord = Variant::GetActiveObject("Word.Application"); } catch(...) { vMSWord = Variant::CreateObject("Word.Application"); } vMSWord.OlePropertySet("Visible", true); vWDocuments = vMSWord.OlePropertyGet("Documents"); vWDocument = vWDocuments.OleFunction("Open", vNom); vSignets = vWDocument.OlePropertyGet("BookMarks"); if (vSignets.OleFunction("Exists", signet)) { vSignet = vSignets.OleFunction("Item", signet); vSignet.OleFunction("Select"); } But once the document is opened, the user can no longer see when an other bookmark has been reached, since the application stays in background. Does anyone know how i can do to make Word displayed in the foreground, or to light-up the document in the taskbar? Thanks!

• Need help with creating complex UITableView items (like the Settings app).

  - by Craig

  I hoping to create a custom Settings view, similar to the Settings application, but with more control over the UI and access to some settings (i need to lock some of the settings). Obvously, there are a variety of UI elements mixed in each row of application's UITableView. For example, the 'Airplane Mode' setting shows a UISwitch, while the 'Wi-Fi' setting has a text value adjacent to the disclosure symbol (''). Further complicating matters, is the grouping of these settings. I have some general questions about the approach I should take: Seems like i need to save the name of the setting, its current value, its grouping, and the type of UI element(s) needed to modify its value. i would like to make use [NSUserDefault standardUserDefaults], but not have these settings appear in the Settings application. I'm guessing that I will need to create my own settings-persistence class. is it better to build each one of these complex UI-element combinations in code or to create a series of custom views based on the UITableViewCell and load the appropriate one? i'm guessing the latter. some of the setting require that i load another view to select its value. assuming that the application is based on the Utility pattern, should the SettingsView manage the navigation stack, rather than having the app delegate do so? Thanks for your time and comments. Craig Buchanan

• Getting values from DataGridView back to XDocument (using LINQ-to-XML)

  - by Pretzel

  Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• How do you efficiently implement a document similarity search system?

  - by Björn Lindqvist

  How do you implement a "similar items" system for items described by a set of tags? In my database, I have three tables, Article, ArticleTag and Tag. Each Article is related to a number of Tags via a many-to-many relationship. For each Article i want to find the five most similar articles to implement a "if you like this article you will like these too" system. I am familiar with Cosine similarity and using that algorithm works very well. But it is way to slow. For each article, I need to iterate over all articles, calculate the cosine similarity for the article pair and then select the five articles with the highest similarity rating. With 200k articles and 30k tags, it takes me half a minute to calculate the similar articles for a single article. So I need another algorithm that produces roughly as good results as cosine similarity but that can be run in realtime and which does not require me to iterate over the whole document corpus each time. Maybe someone can suggest an off-the-shelf solution for this? Most of the search engines I looked at does not enable document similarity searching.
