  • NHibernate Many to Many delete all my data in the table

    - by Daoming Yang
    I would love to thank @Stefan Steinegger and @David helped me out yesterday with many-to-many mapping. I have 3 tables which are "News", "Tags" and "News_Tags" with Many-To-Many relationship and the "News_Tags" is the link table. If I delete one of the news records, the following mappings will delete all my news records which have the same tags. One thing I need to notice, I only allowed unique tag stored in the "Tag" table. This mapping make sense for me, it will delete the tag and related News records, but how can I implement a tagging system with NHibernate? Can anyone give me some suggestion? Many thanks. Daoming. News Mapping: <class name="New" table="News" lazy="false"> <id name="NewID"> <generator class="identity" /> </id> <property name="Title" type="String"></property> <property name="Description" type="String"></property> <set name="TagsList" table="New_Tags" lazy="false" inverse="true" cascade="all"> <key column="NewID" /> <many-to-many class="Tag" column="TagID" /> </set> </class> Tag Mapping: <class name="Tag" table="Tags" lazy="false"> <id name="TagID"> <generator class="identity" /> </id> <property name="TagName" type="String"></property> <property name="DateCreated" type="DateTime"></property> <!--inverse="true" has been defined in the "News mapping"--> <set name="NewsList" table="New_Tags" lazy="false" cascade="all"> <key column="TagID" /> <many-to-many class="New" column="NewID" /> </set> </class>

  • jquery show hidden div

    - by Fahad
    Firstly, I'm sort of embarrassed asking about this, so many people have already asked this question but even after having gone through so many posts, I'm unable to achieve what I want. Basically, a div, initially hidden, has to be displayed on a button click. I tried hiding the div using display:none and hide() and then displaying it using show(), toggle(), and css("display","block"). Using all sorts of combinations of the above, I was still unable to get the result. Code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="css/smoothness/jquery-ui-1.9.2.custom.min.css" rel="stylesheet" type="text/css" /> <script src="jQuery/jquery-1.8.3.min.js" type="text/javascript"></script> <script src="jQuery/jquery-ui-1.9.2.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#one').hide(); $('#Button1').click(function () { $('#one').toggle(500); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="one" style="height: 20px;width:200px; background-color: Red; "> </div> <asp:Button ID="Button1" runat="server" Text="Show" /> </form> </body> </html> On button click, the div is shown for a brief second before it disappears again. The same thing happens if I use show() instead of toggle() in the above code. Again the same thing if I set style="display:none" to the div instead of using hide() and then use show() or toggle(). I also tried using $('#one').css("display","block"); but again, the same result. Can anyone please tell me where I'm going wrong. Just started learning jQuery and it is really frustrating when something apparently so simple will not work. Thanks in advance. :)

  • Find if there is an element repeating itself n/k times

    - by gleb-pendler
    You have an array size n and a constant k (whatever) You can assume the the array is of int type (although it could be of any type) Describe an algorithm that finds if there is an element(s) that repeats itself at least n/k times... if there is return one. Do so in linear time (O(n)) The catch: do this algorithm (or even pseudo-code) using constant memory and running over the array only twice

  • Is there a naming convention for a method that should set the properties of the passed object.

    - by Genady Sergeev
    Hello, I am writing a method that will set the properties of an object passed as a parameter. The method accepts one parameter of type interface and the return type of the method is the same interface. I was wondering if there is some kind of a naming convention for such methods. I was thinking of something like: FillInInterfaceTypeData or InitInterfaceTypeData but both sound clumsy to me. How do you think?

  • How can I embed a conditional comment for IE with innerHTML?

    - by Samuel Charpentier
    Ok so I want to conditionally add this line of code; <!--[if ! IE]> <embed src="logo.svg" type="image/svg+xml" /> <![endif]--> Using: document.getElementById("logo") .innerHTML='...'; In a if()/else() statement and it don't write it! If i get rid of the selective comment ( <!--[if ! IE]><![endif]-->) and only put the SVG ( <embed src="logo.svg" type="image/svg+xml" /> ) it work! what should I do? I found a way around but i think in the Android browser the thing will pop up twice. here's what I've done ( and its Validated stuff!); <!DOCTYPE html> <html> <head> <META CHARSET="UTF-8"> <title>SVG Test</title> <script type="text/javascript"> //<![CDATA[ onload=function() { var ua = navigator.userAgent.toLowerCase(); var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile"); if(isAndroid) { document.getElementById("logo").innerHTML='<img src="fin_palais.png"/>'; } } //]]> </script> </head> <body> <div id="logo"> <!--[if lt IE 9]> <img src="fin_palais.png"/> <![endif]--> <!--[if gte IE 9]><!--> <embed src="fin_palais.svg" type="image/svg+xml" /> <!--<![endif]--> </div> </body>

  • How can i put my form value in javascript array

    - by Lucas van den Abbeele
    I want to make a script where i can put my form in the javascript array invoer[] and display the total It constantly stops working and i searched a lot, i really can't find the right way :D This is my javascript code var strijk = ['broek', 'hemd', 'tshirt', 'lakens', 'korte broek', 'babykledij']; var minuten = [5, 10, 5, 6, 3, 3]; function invoerstrijk() { document.write("<form action='' method='get' name='strijkform'>"); for (var a = 0; a < minuten.length; a++) { document.write(strijk[a] + "<input id='" + strijk[a] + "' name ='" + strijk[a] + "' type='text' />" + "<BR>"); } document.write("<button onclick='opgeven()'>opgeven</button>"); document.write("</form>"); } function opgeven() { var invoer = []; for (var a = 0; a < minuten.length; a++) { invoer[a] = document.getElementByI(strijk[a]).value; } var totaal; for (var a = 0; a < minuten.length; a++) { totaal += parseint(invoer[a]) * parseint(minuten[a]); } document.write("<input name=" + strijk[a] + " type='text' value=" + invoer[a] + " readonly />"); if (invoer != []) { document.write("totaal aantal minuten" + totaal); } else { document.write("geen invoer"); } } my html looks likes this <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <script type="text/javascript" > //my javasccript </script> <button id="B1" onclick="invoerstrijk()" >Nieuwe strijk</button> </body> </html>

  • Gotchas INSERTing into SQLite on Android?

    - by paul.meier
    Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

  • Can this way of storing typed objects be improved?

    - by Pindatjuh
    This is an "can it be improved"-question. Topic: Storing typed objects in memory. Background information: I'm building a compiler for the x86-32 Windows platform for my language. My goal includes typed objects. Idea: Every primitive is a semi-class (it can be used as if it was a normal class, but it's stored more compact). Every class is represented by primitives and some meta-data (containing class-properties, inheritance stuff, etc.). The meta-data is complex: it doesn't use fields but instead context-switches. For primitives, the meta-data is very small, compared to a "real" class, which is alot bigger. This enables another idea that "primitives are objects", in my language, which I found nessecairy. Example: If I have an array of 32 booleans, then the pure content of this array is exactly 4 byte (32 bits of booleans). The meta-data will contain flags that the type is an array of booleans, which contains 32 entries. The meta-data is very compacted, on bit-level: using a sort of "packing" mechanism, which is read by a FSM at runtime, when doing inspection of the type (like when passing the object to methods for checking, etc.) For instance (read from left to right, top to bottom, remember vertical position when going to the right, and check nearest column header for meaning of switch): Primitive? Array? Type-Meta 1 Byte? || Size (1 byte) 1 1 [...] 1 [...] done 0 2 Bytes? || Size (2 bytes) 1 [...] done || Size (4 bytes) 0 [...] done Integer? 1 Byte? 2 Bytes? 0 1 0 1 done 1 done 0 done Boolean? Byte? 0 1 0 done 1 done More-Primitives 0 .... Class-Stuff (Huge) 0 ... (After reaching done the data is inserted. || = byte alignment. [...] is variable sized. ... is not described here, for simplicity. And let's call them cost-based-data-structures.) For an array of 32 booleans containing all true values, the memory for this type would be (read top-down): 1 Primitive 1 Array 1 ArrayType: Primitive 0 Not-Array 0 Not-Integer 1 Boolean 0 Not-Byte (thus bit) 1 Integer Size: 1 Byte 00100000 Array size 01010101 01010101 01010101 01010101 Data (user defined) Thus, 8 bytes represent 32 booleans in an array: 11100101 00100000 01010101 01010101 01010101 01010101 How can I improve this? (Both performance- and memory-consumption wise)

  • logging in continouous loop

    - by Mikkel Jans
    What would be a good way to create logs (with python logging module) inside a constant running loop, without producing a large amount of useless log-files? An example would be a loop that constant list a folder, and does some action when it sees a file of a specific type. I want to log that no files were found, or files were found but of a wrong type, without logging that same line constantly for each folder check, as it might run many times a second.

  • Reading POST data from html form sent to serversocket.

    - by user32167
    i try to write simplest possible server app in Java, displaying html form with textarea input, which after submitting gives me possibility to parse xml typed in that textarea. For now i build simple serversocket based server like that: import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; public class WebServer { protected void start() { ServerSocket s; String gets = ""; System.out.println("Start on port 80"); try { // create the main server socket s = new ServerSocket(80); } catch (Exception e) { System.out.println("Error: " + e); return; } System.out.println("Waiting for connection"); for (;;) { try { // wait for a connection Socket remote = s.accept(); // remote is now the connected socket System.out.println("Connection, sending data."); BufferedReader in = new BufferedReader(new InputStreamReader( remote.getInputStream())); PrintWriter out = new PrintWriter(remote.getOutputStream()); String str = "."; while (!str.equals("")) { str = in.readLine(); if (str.contains("GET")){ gets = str; break; } } out.println("HTTP/1.0 200 OK"); out.println("Content-Type: text/html"); out.println(""); // Send the HTML page String method = "get"; out.print("<html><form method="+method+">"); out.print("<textarea name=we></textarea></br>"); out.print("<input type=text name=a><input type=submit></form></html>"); out.println(gets); out.flush(); remote.close(); } catch (Exception e) { System.out.println("Error: " + e); } } } public static void main(String args[]) { WebServer ws = new WebServer(); ws.start(); } } After form (textarea with xml and one additional text input) is submitted in 'gets' String-type variable I have Urlencoded values of my variables (also displayed on the screen, it looks like that: gets = GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E&a=fooBar HTTP/1.1 What can i do to change GET to POST method (if i simply change it in form and than put " if (str.contains("POST")){" it gives me string like gets = POST / HTTP/1.1 with no variables. And after that, how i can use xml from my textarea field (called 'we')?

  • Custom action getting published multiple times on user's timeline for same object

    - by serpent403
    I just noticed that when I publish an action on the user's timeline for the same object multiple times, using facebook's 'built-in' action type (eg: 'read' an article), i get an error response, something like "action is already associated to the user on this object". But when i try to do the same for a custom action that i created(eg: 'agreed' with an article), I don't get any error message, instead the actions gets published multiple times. I want my custom action to behave just like facebook's default action-type.

  • BizTalk - generating schema from Oracle stored proc with table variable argument

    - by Ron Savage
    I'm trying to set up a simple example project in BizTalk that gets changes made to a table in a SQL Server db and updates a copy of that table in an Oracle db. On the SQL Server side, I have a stored proc named GetItemChanges() that returns a variable number of records. On the Oracle side, I have a stored proc named Update_Item_Region_Table() designed to take a table of records as a parameter so that it can process all the records returned from GetItemChanges() in one call. It is defined like this: create or replace type itemrec is OBJECT ( UPC VARCHAR2(15), REGION VARCHAR2(5), LONG_DESCRIPTION VARCHAR2(50), POS_DESCRIPTION VARCHAR2(30), POS_DEPT VARCHAR2(5), ITEM_SIZE VARCHAR2(10), ITEM_UOM VARCHAR2(5), BRAND VARCHAR2(10), ITEM_STATUS VARCHAR2(5), TIME_STAMP VARCHAR2(20), COSTEDBYWEIGHT INTEGER ); create or replace type tbl_of_rec is table of itemrec; create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec ) IS errcode integer; errmsg varchar2(4000); BEGIN for recIndex in 1 .. Item_Data.COUNT loop update FL_ITEM_REGION_TEST set Region = Item_Data(recIndex).Region, Long_description = Item_Data(recIndex).Long_description, Pos_Description = Item_Data(recIndex).Pos_description, Pos_Dept = Item_Data(recIndex).Pos_dept, Item_Size = Item_Data(recIndex).Item_Size, Item_Uom = Item_Data(recIndex).Item_Uom, Brand = Item_Data(recIndex).Brand, Item_Status = Item_Data(recIndex).Item_Status, Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'), CostedByWeight = Item_Data(recIndex).CostedByWeight where UPC = Item_Data(recIndex).UPC; log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.'); end loop; EXCEPTION WHEN OTHERS THEN errcode := SQLCODE(); errmsg := SQLERRM(); log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...'); END; In my BizTalk project I generate the schemas and binding information for both stored procedures. For the Oracle procedure, I specified a path for the GeneratedUserTypesAssemblyFilePath parameter to generate a DLL to contain the definition of the data types. In the Send Port on the server, I put the path to that Types DLL in the UserAssembliesLoadPath parameter. I created a map to translate the GetItemChanges() schema to the Update_Item_Region_Table() schema. When I run it the data is extracted and transformed fine but causes an exception trying to pass the data to the Oracle proc: *The adapter failed to transmit message going to send port "WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom" with URL "oracledb://dvotst/". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: Custom type mapping for 'HOST_DATA.TBL_OF_REC' is not specified or is invalid.* So it is apparently not getting the information about the custom data type TBL_OF_REC into the Types DLL. Any tips on how to make this work?
