  • Cannot view, use, or open CDs or DVDs in Ubuntu 12.04

    - by user67592
    I am fairly new to Ubuntu 12.04 and I have encountered a rather irritating problem. Whenever I insert a CD or DVD (whether it have data, music, movies, or nothing at all), nothing pops up saying "you have inserted a CD", "play with Rhythmbox?" etc. It doesn't show the CD in the launcher/dock or anything of the sort. This is especially peculiar because not only do I have a standard IDE built-in optical drive, but I have an external USB optical drive. Neither work. In addition, whenever I go to "Computer///" and I click (double click, right click, or even left click) on "CD/DVD Drive" nothing happens, when I right click and select "Open" nothing happens either [for either of the two drives (both are listed in Computer///)] And if I insert a blank disk and go to a disk burning program such as Brasero, and try to burn to the drive it detects no CDs or DVDs of any kind. I'm rather stumped and can't seem to find a question similar to this. :( Thanks for all your help in advance!! :) ~Preston Output of sudo lshw *-cdrom description: DVD-RAM writer product: CD/DVDW TS-H652M vendor: TSSTcorp physical id: 0.0.0 bus info: scsi@5:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0414 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-cdrom description: DVD reader product: DVD Writer 300n vendor: HP physical id: 0.0.0 bus info: scsi@4:0.0.0 logical name: /dev/cdrom2 logical name: /dev/cdrw2 logical name: /dev/dvd2 logical name: /dev/sr1 version: 1.25 serial: [ capabilities: removable audio cd-r cd-rw dvd configuration: status=nodisc

  • What is appropriate way for managing MySQL connection through C#

    - by Sylca
    My question, at the bottom line, is what is the appropriate(best) way to manage our connection towards MySQL db with C#. Well, currently I'm working on some C# (winforms type) <- MySQL application and I've been looking at Server Connections in MySQL Administrator, been witness of execution of my mysql_queries, connection opens an closes, ... an so on! In my C# code I'm working like this and this is an example: public void InsertInto(string qs_insert) { try { conn = new MySqlConnection(cs); conn.Open(); cmd = new MySqlCommand(); cmd.Connection = conn; cmd.CommandText = qs_insert; cmd.ExecuteNonQuery(); } catch (MySqlException ex) { MessageBox.Show(ex.ToString()); } finally { if (conn != null) { conn.Close(); } } } Meaning, every time I want to insert something in db table I call this table and pass insert query string to this method. Connection is established, opened, query executed, connection closed. So, we could conclude that this is the way I manage MySQL connection. For me and my point of view, currently, this works and its enough for my requirements. Well, you have Java & Hibernate, C# & Entity Framework and I'm doing this :-/ and it's confusing me. Should I use MySQL with Entity Framework? What is the best way for collaboration between C# and MySQL? I don't want to worry about is connection that I've opened closed, can that same connection be faster, ...

  • Binding navigation property to RadGrid while using EntityDataSource control

    - by Matrix
    I'm new to Entity Framework and I got stuck in an issue while trying to bind a navigation property (foreign key reference) to a dropdownlist. I have Telerik RadGrid control which gets the data using a EntityDataSource control. Here is the model description: Applications: AppId, AppName, ServerId Servers: ServerId, ServerName The Applicaitons.ServerId is a foreign key reference to Servers.ServerId. The RadGrid lists the applications and allows the user to insert/update/delete an application. I want to show the server names as a dropdownlist in edit mode which I'm not able to. . Here is my aspx code: <telerik:RadGrid ID="gridApplications" runat="server" Skin="Sunset" AllowAutomaticInserts="True" AllowAutomaticDeletes="True" AllowPaging="True" AllowAutomaticUpdates="True" AutoGenerateColumns="False" OnItemCreated="gridApplications_ItemCreated" DataSourceID="applicationsEntityDataSource" Width="50%" OnItemInserted="gridApplications_ItemInserted" OnItemUpdated="gridApplications_ItemUpdated" OnItemDeleted="gridApplications_ItemDeleted" GridLines="None"> <MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="False" DataKeyNames="AppId" DataSourceID="applicationsEntityDataSource"> <RowIndicatorColumn> <HeaderStyle Width="20px" /> </RowIndicatorColumn> <ExpandCollapseColumn> <HeaderStyle Width="20px" /> </ExpandCollapseColumn> <Columns> <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" HeaderText="Edit" ItemStyle-Width="10%"> </telerik:GridEditCommandColumn> <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ConfirmText="Are you sure you want to delete this application?"

Application cannot be inserted. Reason: Entities in 'AnalyticsEntities.Applications' participate in the 'FK_Servers_Applications' relationship. 0 related 'Servers' were found. 1 'Servers' is expected. My question is, how do you bind the navigation property and load the values in the DropDownList/RadComboBox control?

  • Foreign Key constraint violation when persisting a many-to-one class

  • XmlException - inserting attribute gives "unexpected token" exception

    - by Anders Svensson
    Hi, I have an XmlDocument object in C# that I transform, using XslTransform, to html. In the stylesheet I insert an id attribute in a span tag, taking the id from an element in the XmlDocument. Here is the template for the element: <xsl:template match="word"> <span> <xsl:attribute name="id"><xsl:value-of select="@id"></xsl:value-of></xsl:attribute> <xsl:apply-templates/> </span> </xsl:template> But then I want to process the result document as an xhtml document (using the XmlDocument dom). So I'm taking a selected element in the html, creating a range out of it, and try to load the element using XmlLoad(): wordElem.LoadXml(range.htmlText); But this gives me the following exception: "'598' is an unexpected token. The expected token is '"' or '''. Line 1, position 10." And if I move the cursor over the range.htmlText, I see the tags for the element, and the "id" shows without quotes, which confuses me (i.e.SPAN id=598 instead of SPAN id="598"). To confuse the matter further, if I insert a blank space or something like that in the value of the id in the stylesheet, it works fine, i.e.: <span> <xsl:attribute name="id"><xsl:text> </xsl:text> <xsl:value-of select="@id"></xsl:value-of></xsl:attribute> <xsl:apply-templates/> </span> (Notice the whitespace in the xsl:text element). Now if I move the cursor over the range.htmlText, I see an id with quotes as usual in attributes (and as it shows if I open the html file in notepad or something). What is going on here? Why can't I insert an attribute this way and have a result that is acceptable as xhtml for XmlDocument to read? I feel I am missing something fundamental, but all this surprises me, since I do this sort of transformations using xsl:attribute to insert attributes all the time for other types of xsl transformations. Why doesn't XmlDocument accept this value? By the way, it doesn't matter if it is an id attribute. i have tried with the "class" attribute, "style" etc, and also using literal values such as "style" and setting the value to "color:red" and so on. The compiler always complains it is an unvalid token, and does not include quotes for the value unless there is a whitespace or something else in there (linebreaks etc.). I hope I have provided enough information. Any help will be greatly appreciated. Basically, what I want to accomplish is set an id in a span element in html, select a word in a webbrowser control with this document loaded, and get the id attribute out of the selected element. I've accomplished everything, and can actually do what I want, but only if I use regex e.g. to get the attribute value, and I want to be able to use XmlDocument instead to simply get the value out of the attribute directly. I'm sure I'm missing something simple, but if so please tell me. Regards, Anders

  • Create attribute in XML

    - by user560411
    Hello. I have the following php code that adds data into XML and works correctly. However, in my second step I will create a form that deletes some of the elements. The problem is that I want to add an ID number and then the PHP file will search for it and delete entire node. My question is how can i add an ID into CD for this to work ? For example ( <cd id="xxxx"> ) Also, any ideas or examples of a code that deletes CD having the ID would be appreciate. insert.php ( my index file with the form ) <h1>Playlist</h1> <form action="insert2.php" method="post"> <fieldset> <label for="TITLE">TITLE:</label><input type="text" id="title" name="title" /><br /> <label for="title">BAND:</label> <input type="text" id="band" name="band"/><br /> <label for="path">YEAR:</label> <input type="text" id="year" name="year" /> <br /> <input type="submit" /> </fieldset> </form> <h2>Current entries:</h2> <p>TITLE - BAND - YEAR</p> <?php $doc = new DOMDocument(); $doc->load( 'insert.xml' ); $CATEGORIES = $doc->getElementsByTagName( "CD" ); foreach( $CATEGORIES as $CD ) { $TITLES = $CD->getElementsByTagName( "TITLE" ); $TITLE = $TITLES->item(0)->nodeValue; $BANDS= $CD->getElementsByTagName( "BAND" ); $BAND= $BANDS->item(0)->nodeValue; $YEARS = $CD->getElementsByTagName( "YEAR" ); $YEAR = $YEARS->item(0)->nodeValue; echo "<b>$TITLE - $BAND - $YEAR\n</b><br>"; } ?> inser2.php ( the main code ) <?php $CD = array( 'TITLE' => $_POST['title'], 'BAND' => $_POST['band'], 'YEAR' => $_POST['year'], ); $doc = new DOMDocument(); $doc->load( 'insert.xml' ); $doc->formatOutput = true; $r = $doc->getElementsByTagName("CATEGORIES")->item(0); $b = $doc->createElement("CD"); $TITLE = $doc->createElement("TITLE"); $TITLE->appendChild( $doc->createTextNode( $CD["TITLE"] ) ); $b->appendChild( $TITLE ); $BAND = $doc->createElement("BAND"); $BAND->appendChild( $doc->createTextNode( $CD["BAND"] ) ); $b->appendChild( $BAND ); $YEAR = $doc->createElement("YEAR"); $YEAR->appendChild( $doc->createTextNode( $CD["YEAR"] ) ); $b->appendChild( $YEAR ); $r->appendChild( $b ); $doc->save("insert.xml"); ?> the XML file <?xml version="1.0" encoding="utf-8"?> <MY_CD> <CATEGORIES> <CD> <TITLE>NEVER MIND THE BOLLOCKS</TITLE> <BAND>SEX PISTOLS</BAND> <YEAR>1977</YEAR> </CD> <CD> <TITLE>NEVERMIND</TITLE> <BAND>NIRVANA</BAND> <YEAR>1991</YEAR> </CD> </CATEGORIES> </MY_CD>

  • What is wrong with my SQL syntax here?

    - by CT
    I'm trying to create a IT asset database with a web front end. I've gathered some data from forms using POST as well as one variable that had already written to a cookie.

  • Why does my performance slow to a crawl I move methods into a base class?

    - by Juliet
    I'm writing different implementations of immutable binary trees in C#, and I wanted my trees to inherit some common methods from a base class. However, I find. I have lots of binary tree data structures to implement, and I wanted move some common methods into in a base binary tree class. Unfortunately, classes which derive from the base class are abysmally slow. Non-derived classes perform adequately. Here are two nearly identical implementations of an AVL tree to demonstrate: AvlTree: http://pastebin.com/V4WWUAyT DerivedAvlTree: http://pastebin.com/PussQDmN The two trees have the exact same code, but I've moved the DerivedAvlTree.Insert method in base class. Here's a test app: using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using Juliet.Collections.Immutable; namespace ConsoleApplication1 { class Program { const int VALUE_COUNT = 5000; static void Main(string[] args) { var avlTreeTimes = TimeIt(TestAvlTree); var derivedAvlTreeTimes = TimeIt(TestDerivedAvlTree); Console.WriteLine("avlTreeTimes: {0}, derivedAvlTreeTimes: {1}", avlTreeTimes, derivedAvlTreeTimes); } static double TimeIt(Func<int, int> f) { var seeds = new int[] { 314159265, 271828183, 231406926, 141421356, 161803399, 266514414, 15485867, 122949829, 198491329, 42 }; var times = new List<double>(); foreach (int seed in seeds) { var sw = Stopwatch.StartNew(); f(seed); sw.Stop(); times.Add(sw.Elapsed.TotalMilliseconds); } // throwing away top and bottom results times.Sort(); times.RemoveAt(0); times.RemoveAt(times.Count - 1); return times.Average(); } static int TestAvlTree(int seed) { var rnd = new System.Random(seed); var avlTree = AvlTree<double>.Create((x, y) => x.CompareTo(y)); for (int i = 0; i < VALUE_COUNT; i++) { avlTree = avlTree.Insert(rnd.NextDouble()); } return avlTree.Count; } static int TestDerivedAvlTree(int seed) { var rnd = new System.Random(seed); var avlTree2 = DerivedAvlTree<double>.Create((x, y) => x.CompareTo(y)); for (int i = 0; i < VALUE_COUNT; i++) { avlTree2 = avlTree2.Insert(rnd.NextDouble()); } return avlTree2.Count; } } } AvlTree: inserts 5000 items in 121 ms DerivedAvlTree: inserts 5000 items in 2182 ms My profiler indicates that the program spends an inordinate amount of time in BaseBinaryTree.Insert. Anyone whose interested can see the EQATEC log file I've created with the code above (you'll need EQATEC profiler to make sense of file). I really want to use a common base class for all of my binary trees, but I can't do that if performance will suffer. What causes my DerivedAvlTree to perform so badly, and what can I do to fix it?

  • How to prevent PHP variables from being arrays or objects?

    - by MJB
    I think that (the title) is the problem I am having. I set up a MySQL connection, I read an XML file, and then I insert those values into a table by looping through the elements. The problem is, instead of inserting only 1 record, sometimes I insert 2 or 3 or 4. It seems to depend on the previous values I have read. I think I am reinitializing the variables, but I guess I am missing something -- hopefully something simple. Here is my code. I originally had about 20 columns, but I shortened the included version to make it easier to read. $ctr = 0; $sql = "insert into csd (id,type,nickname,hostname,username,password) ". "values (?,?,?,?,?,?)"; $cur = $db->prepare($sql); for ($ctr = 0; $ctr < $expected_count; $ctr++) { unset($bind_vars,$dat); $lbl = "csd_{$ctr}"; $dat['type'] = (string) $ref->itm->csds->$lbl->type; $dat['nickname'] = (string) $ref->itm->csds->$lbl->nickname; $dat['hostname'] = (string) $ref->itm->csds->$lbl->hostname; $dat['username'] = (string) $ref->itm->csds->$lbl->username; $dat['password'] = (string) $ref->itm->csds->$lbl->password; $bind_vars = array( $id,$dat['$type'], $dat['$nickname'], $dat['$hostname'], $dat['$username'], $dat['$password']); print_r ($bind_vars); $res = $db->execute($cur, $bind_vars); } P.S. I also tagged this SimpleXML because that is how I am reading the file, though that code is not included above. It looks like this: $ref = simplexml_load_file($file); UPDATE: I've changed the code around as per suggestions, and now it is not always the same pattern, but it is equally broken. When I display the bind array before inserting, it looks like this. Note that I also count the rows before and after, so there are 0 rows, then I insert 1, then there are 2: 0 CSDs on that ITEM now. Array ( [0] => 2 [1] => 0 [2] => [3] => X [4] => XYZ [5] => [6] => [7] => [8] => audio [9] => [10] => 192.168.0.50 [11] => 192.168.0.3 [12] => 255.255.255.0 [13] => 255.255.255.0 [14] => [15] => [16] => [17] => 21 [18] => 5 [19] => Y [20] => /dir ) 2 CSDs on that ITEM now.

  • BFS Shortest Path: Edge weight either 1 or 2

    - by Hackster
    I am trying to implement a shortest path algorithm using BFS. That is I am trying to find the shortest path from a specified vertex to every other vertex. However, its a special case where all edge weights are either 1 or 2. I know it could be done with Dijkstra's algorithm but I must use Breadth First Search. So far I have a working version of BFS that searches first for a vertex connected with an edge of weight 1. If it cannot find it, then returns a vertex connected with an edge of weight 2. After thinking about it, this is not the correct way to find the shortest path. The problem is I cannot think of any reasoning why BFS would work with weights 1 or 2, as opposed to any weight. Here is the code: public void addEdge(int start, int end, int weight) { adjMat[start][end] = 1; adjMat[end][start] = 1; edge_weight[start][end] = weight; edge_weight[end][start] = weight; } // ------------------------------------------------------------- public void bfs() // breadth-first search { // begin at vertex 0 vertexList[0].wasVisited = true; // mark it displayVertex(0); // display it theQueue.insert(0); // insert at tail int v2; while( !theQueue.isEmpty() ) // until queue empty, { int v1 = theQueue.remove(); // remove vertex at head // until it has no unvisited neighbors while( (v2=getAdjUnvisitedVertex(v1)) != -1 ){// get one, vertexList[v2].wasVisited = true; // mark it displayVertex(v2); // display it theQueue.insert(v2); // insert it } } // end while(queue not empty) // queue is empty, so we're done for(int j=0; j<nVerts; j++) // reset flags vertexList[j].wasVisited = false; } // end bfs() // ------------------------------------------------------------- // returns an unvisited vertex adj to v -- ****WITH WEIGHT 1**** public int getAdjUnvisitedVertex(int v) { for (int j = 0; j < nVerts; j++) if (adjMat[v][j] == 1 && vertexList[j].wasVisited == false && edge_weight[v][j] == 1){ //System.out.println("Vertex found with 1:"+ vertexList[j].label); return j; } for (int k = 0; k < nVerts; k++) if (adjMat[v][k] == 1 && vertexList[k].wasVisited == false && edge_weight[v][k] == 2){ //System.out.println("Vertex found with 2:"+vertexList[k].label); return k; } return -1; } // end getAdjUnvisitedVertex() // ------------------------------------------------------------- } //////////////////////////////////////////////////////////////// public class BFS{ public static void main(String[] args) { Graph theGraph = new Graph(); theGraph.addVertex('A'); // 0 (start for bfs) theGraph.addVertex('B'); // 1 theGraph.addVertex('C'); // 2 theGraph.addEdge(0, 1,2); // AB theGraph.addEdge(1, 2,1); // BC theGraph.addEdge(2, 0,1); // AD System.out.print("Visits: "); theGraph.bfs(); // breadth-first search System.out.println(); } // end main() } The problem then is, that I don't know why BFS can work for the shortest path problem with edges of weight 1 or 2 as opposed to any edges of any weight. Any help is appreciated. Thanks!

  • Data Warehouse ETL slow - change primary key in dimension?

    - by Jubbles
    I have a working MySQL data warehouse that is organized as a star schema and I am using Talend Open Studio for Data Integration 5.1 to create the ETL process. I would like this process to run once per day. I have estimated that one of the dimension tables (dimUser) will have approximately 2 million records and 23 columns. I created a small test ETL process in Talend that worked, but given the amount of data that may need to be updated daily, the current performance will not cut it. It takes the ETL process four minutes to UPDATE or INSERT 100 records to dimUser. If I assumed a linear relationship between the count of records and the amount of time to UPDATE or INSERT, then there is no way the ETL can finish in 3-4 hours (my hope), let alone one day. Since I'm unfamiliar with Java, I wrote the ETL as a Python script and ran into the same problem. Although, I did discover that if I did only INSERT, the process went much faster. I am pretty sure that the bottleneck is caused by the UPDATE statements. The primary key in dimUser is an auto-increment integer. My friend suggested that I scrap this primary key and replace it with a multi-field primary key (in my case, 2-3 fields). Before I rip the test data out of my warehouse and change the schema, can anyone provide suggestions or guidelines related to the design of the data warehouse the ETL process how realistic it is to have an ETL process INSERT or UPDATE a few million records each day will my friend's suggestion significantly help If you need any further information, just let me know and I'll post it. UPDATE - additional information: mysql> describe dimUser; Field Type Null Key Default Extra user_key int(10) unsigned NO PRI NULL auto_increment id_A int(10) unsigned NO NULL id_B int(10) unsigned NO NULL field_4 tinyint(4) unsigned NO 0 field_5 varchar(50) YES NULL city varchar(50) YES NULL state varchar(2) YES NULL country varchar(50) YES NULL zip_code varchar(10) NO 99999 field_10 tinyint(1) NO 0 field_11 tinyint(1) NO 0 field_12 tinyint(1) NO 0 field_13 tinyint(1) NO 1 field_14 tinyint(1) NO 0 field_15 tinyint(1) NO 0 field_16 tinyint(1) NO 0 field_17 tinyint(1) NO 1 field_18 tinyint(1) NO 0 field_19 tinyint(1) NO 0 field_20 tinyint(1) NO 0 create_date datetime NO 2012-01-01 00:00:00 last_update datetime NO 2012-01-01 00:00:00 run_id int(10) unsigned NO 999 I used a surrogate key because I had read that it was good practice. Since, from a business perspective, I want to keep aware of potential fraudulent activity (say for 200 days a user is associated with state X and then the next day they are associated with state Y - they could have moved or their account could have been compromised), so that is why geographic data is kept. The field id_B may have a few distinct values of id_A associated with it, but I am interested in knowing distinct (id_A, id_B) tuples. In the context of this information, my friend suggested that something like (id_A, id_B, zip_code) be the primary key. For the large majority of daily ETL processes (80%), I only expect the following fields to be updated for existing records: field_10 - field_14, last_update, and run_id (this field is a foreign key to my etlLog table and is used for ETL auditing purposes).

  • Counting number of times an item occurs in a linked list

    - by HanaCHaN92
    Here is the assignment: Here's the assignment: Implement a method countValue() that counts the number of times an item occurs in a linked list. Remember to use the STL list. int countValue(list front, const int item); Generate 20 random numbers in the range of 0 to 4, and insert each number in the linked list. Output the list by using a method which you would call writeLinkedList which you would add to the ListP.cpp. In a loop, call the method countValue() , and display the number of occurrences of each value from 0 to 4 in the list. Remember that all the above is to be included in the file ListP.ccp Run: 2 3 4 0 1 0 2 4 2 3 3 4 3 3 3 0 0 2 0 2 0 : 5, 1 : 1, 2 : 5, 3 : 6, 4 : 3 and here is what I have so far: #include<iostream> #include<list> #include<tchar.h> int countValue(list<int> front, const int item); using namespace std; int _tmain(int argc, _TCHAR* argv[]){ list<int> front; int listCount; cout << "Enter the size of the list: "; cin >> listCount; for (int i = 1; i <= listCount; i++) front.insert(rand()%5); cout << "Original List of Values: " << endl; //writeLinkedList(front, " "); cout << endl; for(int j=0;j<5;++j) cout << countValue (front,j) << endl; cout << endl; return 0; } int countValue(list<int> front, const int item) { int count0; int count1; int count2; int count3; int count4; list<int> *List; for(list<int>::iterator i = front.begin(); i != front.end(); i++) { if(List->item == 0) { count0++; } if(List->item == 1) { count1++; } if(List->item == 2) { count2++; } if(List->item == 3) { count2++; }if(List->item == 4) { count4++; } } } And here are the errors: error C2065: 'list' : undeclared identifier line 5 error C2062: type 'int' unexpected line 5 error C2661: 'std::list<_Ty>::insert' : no overloaded function takes 1 arguments line 16 error C3861: 'countValue': identifier not found line 21 IntelliSense: no instance of overloaded function "std::list<_Ty, _Ax>::insert [with _Ty=int, _Ax=std::allocator<int>]" matches the argument list line 16 IntelliSense: too few arguments in function call line 16 error C2039: 'item': is not a member of 'std::list<_Ty>' lines 34, 38, 42, 46, 49 IntelliSense: declaration is incompatible with "int countValue" (declared at line 5) line 25 IntelliSense: class "std::list<int, std:: allocator<int>>" has no member "item" lines 34, 38, 42, 46, 49 I just want to know what I've done wrong and how to fix it and also if someone could help me figure out if I'm doing the countValue function wrong or not based on the instructions I would really appreciate it.
