  • Database Programming in C#, returning output from Stored Proc

    - by jpavlov
    I am working at gaining an understanding at how to interface stored procedures with applications. My example is simple, but it doesn't display my columns and rows in the command prompt, instead it display System.Data.SqlClient.SqlDataReader. How do I display the rows from my stored procudure? ----Stored Proc-- ALTER PROCEDURE dbo.SelectID AS SELECT * FROM tb_User; ----- Below is the code: using System; using System.Data.SqlClient; using System.IO; namespace ExecuteStoredProc { class Program { static void Main(string[] args) { SqlConnection cnnUserMan; SqlCommand cmmUser; //SqlDataReader drdUser; //Instantiate and open the connection cnnUserMan = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=c:\\Program Files\\Microsoft SQL Server\\MSSQL10.SQLEXPRESS\\MSSQL\\DATA\\UserDB.mdf; Integrated Security=True;Connect Timeout=30;User Instance=True"); cnnUserMan.Open(); //Instantiate and initialize command cmmUser = new SqlCommand("SelectID", cnnUserMan); cmmUser.CommandType = System.Data.CommandType.StoredProcedure; //drdUser = cmmUser.ExecuteReader(); Console.WriteLine(cmmUser.ExecuteReader()); Console.ReadLine(); } } } Thanks.

    - by mumich
    Hi guys, I've been stuck with this for past two days. I've go java function stored in Oracle system which is supposed to copy image from local drive do remote database and store it in BLOB - it's called CopyBLOB and looks like this: import java.sql.*; import oracle.sql.*; import java.io.*; public class CopyBLOB { static int id; static String fileName = null; static Connection conn = null; public CopyBLOB(int idz, String f) { id = idz; fileName = f; } public static void copy(int ident, String path) throws SQLException, FileNotFoundException { CopyBLOB cpB = new CopyBLOB(ident, path); cpB.getConnection(); cpB.callUpdate(id, fileName); } public void getConnection() throws SQLException { DriverManager.registerDriver (new oracle.jdbc.OracleDriver()); try { conn = DriverManager.getConnection("jdbc:oracle:thin:@oraserv.ms.mff.cuni.cz:1521:db", "xxx", "xxx"); } catch (SQLException sqlex) { System.out.println("SQLException while getting db connection: "+sqlex); if (conn != null) conn.close(); } catch (Exception ex) { System.out.println("Exception while getting db connection: "+ex); if (conn != null) conn.close(); } } public void callUpdate(int id, String file ) throws SQLException, FileNotFoundException { CallableStatement cs = null; try { conn.setAutoCommit(false); File f = new File(file); FileInputStream fin = new FileInputStream(f); cs = (CallableStatement) conn.prepareCall( "begin add_image(?,?); end;" ); cs.setInt(1, id ); cs.setBinaryStream(2, fin, (int) f.length()); cs.execute(); conn.setAutoCommit(true); } catch ( SQLException sqlex ) { System.out.println("SQLException in callUpdateUsingStream method of given status : " + sqlex.getMessage() ); } catch ( FileNotFoundException fnex ) { System.out.println("FileNotFoundException in callUpdateUsingStream method of given status : " + fnex.getMessage() ); } finally { try { if (cs != null) cs.close(); if (conn != null) conn.close(); } catch ( Exception ex ) { System.out.println("Some exception in callUpdateUsingStream method of given status : " + ex.getMessage( ) ); } } } } The wrapper function is defined in package "MyPackage" as folows: procedure image_adder( id varchar2, path varchar2 ) AS language java name 'CopyBLOB.copy(java.lang.String, java.lang.String)'; And the inserting function called image_add is as simple as this: procedure add_image( id numeric(10), pic blob) AS BEGIN insert into pictures values (seq_pic.nextval, id, pic); END add_image; Now the problem: When I type call MyPackage.image_adder(1, 'd:\samples\img.jpg'); I get the ORA-29531 Error: No method copy in class CopyBLOB.

  • Java: Multithreading & UDP Socket Programming

    - by Ravi
    I am new to multithreading & socket programming in Java. I would like to know what is the best way to implement 2 threads - one for receiving a socket and one for sending a socket. If what I am trying to do sounds absurd, pls let me know why! The code is largely inspired from Sun's tutorials online.I want to use Multicast sockets so that I can work with a multicast group. class server extends Thread { static protected MulticastSocket socket = null; protected BufferedReader in = null; public InetAddress group; private static class receive implements Runnable { public void run() { try { byte[] buf = new byte[256]; DatagramPacket pkt = new DatagramPacket(buf,buf.length); socket.receive(pkt); String received = new String(pkt.getData(),0,pkt.getLength()); System.out.println("From server@" + received); Thread.sleep(1000); } catch (IOException e) { System.out.println("Error:"+e); } catch (InterruptedException e) { System.out.println("Error:"+e); } } } public server() throws IOException { super("server"); socket = new MulticastSocket(4446); group = InetAddress.getByName("239.231.12.3"); socket.joinGroup(group); } public void run() { while(1>0) { try { byte[] buf = new byte[256]; DatagramPacket pkt = new DatagramPacket(buf,buf.length); //String msg = reader.readLine(); String pid = ManagementFactory.getRuntimeMXBean().getName(); buf = pid.getBytes(); pkt = new DatagramPacket(buf,buf.length,group,4446); socket.send(pkt); Thread t = new Thread(new receive()); t.start(); while(t.isAlive()) { t.join(1000); } sleep(1); } catch (IOException e) { System.out.println("Error:"+e); } catch (InterruptedException e) { System.out.println("Error:"+e); } } //socket.close(); } public static void main(String[] args) throws IOException { new server().start(); //System.out.println("Hello"); } }

  • Partially Modifying an XML serialized document.

    - by Stacey
    I have an XML document, several actually, that will be editable via a front-end UI. I've discovered a problem with this approach (other than the fact that it is using xml files instead of a database... but I cannot change that right now). If one user makes a change while another user is in the process of making a change, then the second one's changes will overwrite the first. I need to be able to request objects from the xml files, change them, and then submit the changes back to the xml file without re-writing the entire file. I've got my entire xml access class posted here (which was formed thanks to wonderful help from stackoverflow!) using System; using System.Linq; using System.Collections; using System.Collections.Generic; namespace Repositories { /// <summary> /// A file base repository represents a data backing that is stored in an .xml file. /// </summary> public partial class Repository<T> : IRepository { /// <summary> /// Default constructor for a file repository /// </summary> public Repository() { } /// <summary> /// Initialize a basic repository with a filename. This will have to be passed from a context to be mapped. /// </summary> /// <param name="filename"></param> public Repository(string filename) { FileName = filename; } /// <summary> /// Discovers a single item from this repository. /// </summary> /// <typeparam name="TItem">The type of item to recover.</typeparam> /// <typeparam name="TCollection">The collection the item belongs to.</typeparam> /// <param name="expression"></param> /// <returns></returns> public TItem Single<TItem, TCollection>(Predicate<TItem> expression) where TCollection : IDisposable, IEnumerable<TItem> { using (var list = List<TCollection>()) { return list.Single(i => expression(i)); } } /// <summary> /// Discovers a collection from the repository, /// </summary> /// <typeparam name="TCollection"></typeparam> /// <returns></returns> public TCollection List<TCollection>() where TCollection : IDisposable { using (var list = System.Xml.Serializer.Deserialize<TCollection>(FileName)) { return (TCollection)list; } } /// <summary> /// Discovers a single item from this repository. /// </summary> /// <typeparam name="TItem">The type of item to recover.</typeparam> /// <typeparam name="TCollection">The collection the item belongs to.</typeparam> /// <param name="expression"></param> /// <returns></returns> public List<TItem> Select<TItem, TCollection>(Predicate<TItem> expression) where TCollection : IDisposable, IEnumerable<TItem> { using (var list = List<TCollection>()) { return list.Where( i => expression(i) ).ToList<TItem>(); } } /// <summary> /// Attempts to save an entire collection. /// </summary> /// <typeparam name="TCollection"></typeparam> /// <param name="collection"></param> /// <returns></returns> public Boolean Save<TCollection>(TCollection collection) { try { // load the collection into an xml reader and try to serialize it.

  • Lotus Notes won't open a hyperlink/uri in a browser!

    - by Andy O
    I'm still new to Lotus, but I have LN 8.0.2, and have it set up to open hyperlinks "using the browser i have set as the default for this operating system" which in my case is Firefox 3.6.13. If I try to select "use the browser embedded in this client" then it just forgets it after I click save (ie if i go back into preferences it's reset to the default for this operating system option) Windows XP SP 3. Whenever I click on a link in an email...memo... then it does nothing and flashes an underscore underneath it. It's so basic and so annoying there must be something I'm missing. Any help please!

  • Is it possible to call the main(String[] args) after catching an exception?

    I'm working on a Serpinski triangle program that asks the user for the levels of triangles to draw. In the interests of idiot-proofing my program, I put this in: Scanner input= new Scanner(System.in); System.out.println(msg); try { level= input.nextInt(); } catch (Exception e) { System.out.print(warning); //restart main method } Is it possible, if the user punches in a letter or symbol, to restart the main method after the exception has been caught?

  • Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

    - by Steven Murawski
    I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)

I generation is simple, base FlowLayoutPanel have other FlowLayoutPanels, for each have a Label and TextBox with DataBinding. Problem is this is VERY SLOW, up to 20 seconds, i drawing less than 100 controls, from Performace Session i know a problem is on 70% procesing functions: System.Windows.Forms.Control.ControlCollection.Add(class System.Windows.Forms.Control) System.Windows.Forms.ControlBindingsCollection.Add(class System.Windows.Forms.Binding) How i can do with this?

  • Problems with with A* algorithm

    - by V_Programmer
    I'm trying to implement the A* algorithm in Java. I followed this tutorial,in particular, this pseudocode: http://theory.stanford.edu/~amitp/GameProgramming/ImplementationNotes.html The problem is my code doesn't work. It goes into an infinite loop. I really don't know why this happens... I suspect that the problem are in F = G + H function implemented in Graph constructors. I suspect I am not calculate the neighbor F correclty. Here's my code: List<Graph> open; List<Graph> close; private void createRouteAStar(Unit u) { open = new ArrayList<Graph>(); close = new ArrayList<Graph>(); u.ai_route_endX = 11; u.ai_route_endY = 5; List<Graph> neigh; int index; int i; boolean finish = false; Graph current; int cost; Graph start = new Graph(u.xMap, u.yMap, 0, ManhattanDistance(u.xMap, u.yMap, u.ai_route_endX, u.ai_route_endY)); open.add(start); current = start; while(!finish) { index = findLowerF(); current = new Graph(open, index); System.out.println(current.x); System.out.println(current.y); if (current.x == u.ai_route_endX && current.y == u.ai_route_endY) { finish = true; } else { close.add(current); neigh = current.getNeighbors(); for (i = 0; i < neigh.size(); i++) { cost = current.g + ManhattanDistance(current.x, current.y, neigh.get(i).x, neigh.get(i).y); if (open.contains(neigh.get(i)) && cost < neigh.get(i).g) { open.remove(open.indexOf(neigh)); } else if (close.contains(neigh.get(i)) && cost < neigh.get(i).g) { close.remove(close.indexOf(neigh)); } else if (!open.contains(neigh.get(i)) && !close.contains(neigh.get(i))) { neigh.get(i).g = cost; neigh.get(i).f = cost + ManhattanDistance(neigh.get(i).x, neigh.get(i).y, u.ai_route_endX, u.ai_route_endY); neigh.get(i).setParent(current); open.add(neigh.get(i)); } } } } System.out.println("step"); for (i=0; i < close.size(); i++) { if (close.get(i).parent != null) { System.out.println(i); System.out.println(close.get(i).parent.x); System.out.println(close.get(i).parent.y); } } } private int findLowerF() { int i; int min = 10000; int minIndex = -1; for (i=0; i < open.size(); i++) { if (open.get(i).f < min) { min = open.get(i).f; minIndex = i; System.out.println("min"); System.out.println(min); } } return minIndex; } private int ManhattanDistance(int ax, int ay, int bx, int by) { return Math.abs(ax-bx) + Math.abs(ay-by); } And, as I've said. I suspect that the Graph class has the main problem. However I've not been able to detect and fix it. public class Graph { int x, y; int f,g,h; Graph parent; public Graph(int x, int y, int g, int h) { this.x = x; this.y = y; this.g = g; this.h = h; this.f = g + h; } public Graph(List<Graph> list, int index) { this.x = list.get(index).x; this.y = list.get(index).y; this.g = list.get(index).g; this.h = list.get(index).h; this.f = list.get(index).f; this.parent = list.get(index).parent; } public Graph(Graph gp) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = gp.f; } public Graph(Graph gp, Graph parent) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = g + h; this.parent = parent; } public List<Graph> getNeighbors() { List<Graph> aux = new ArrayList<Graph>(); aux.add(new Graph(x+1, y, g,h)); aux.add(new Graph(x-1, y, g,h)); aux.add(new Graph(x, y+1, g,h)); aux.add(new Graph(x, y-1, g,h)); return aux; } public void setParent(Graph g) { parent = g; } } Little Edit: Using the System.out and the Debugger I discovered that the program ALWAYS is check the same "current" graph, (15,8) which is the (u.xMap, u.yMap) position. Looks like it keeps forever in the first step.

  • When I try to redefine a variable, I get an index out of bounds error

    I'm building a program to act as a calculator with memory, so you can give variables and their values.

  • c# how to set up and use session state from preinit

    - by Praesagus
    OK so to set and read variables from the current session String Myvar =(string) System.Web.HttpContext.Current.Session[“MyVariable”] To set System.Web.HttpContext.Current.Session[“MyVariable”] = “NewValue” I can do neither, I get a System.NullReferenceException: Object reference not set to an instance of an object. from System.Web.HttpContext.Current.Session. In my web.config I have <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" cookieless="false" timeout="20"> </sessionState> I have read a dozen articles on the the necessity of IHttpHandler and an IRequiresSessionState interface. I think the issue may be caused because I am requesting this information in Page_PreInit. I found a solution in a stack overflow article but I don't seem be using it properly to actually make this go. I am not sure what I am missing. Thanks in advance.

  • SSL_accept hangs... sometimes ( C, linux, openssl )

    - by zbigh
    I'm currently working on an embedded linux system. There are two crucial client applications on the system that connect to an external server ( on another embedded system, all written in C ). The two apps use different certificates. The ssl connection works... At least usually, but from time to time an error occures: the server hangs on SSL_accept() when accepting connection from one of the applications - the one using older certificates. Restarting the server application does not help, nor does restarting the client - the only way is to reboot the server system, unless I create a symbilic link to the new certificates used by the other app - only then will restarting the server app work. Never does the error occur when both applications use the same, new certificate. Could this happen due to some strange openssl cache or something like that?

  • matlab: how to transform screen pixels into specific coordinates

    - by user3137385
    I have to draw a curve captured on a image using screen pixels (mouse clicks) into a coordinate system. E.g.: Pixels on the screen, from left to right (130 px to 970 px) correspond to the x-axis of my coordinate system (1000 to 6000). Pixels from bottom to top (670 to 99) correspond to the y-axis of coordinate system (0 to 1.2). How can this be done? Maybe there's a function in matlab doing something like that? Some more explanation: I have a jpg image of a curve on a coordinate system. I've got pixel positions (x,y) of several points on that curve. Now I want to plot same curve into a matlab figure with same x and y axis as on the jpg image.

  • why create CLSID_CaptureGraphBuilder2 instance always failed in a machine

    - by Yigang Wu
    It's a real strange issue, the machine information below is from DXDiag. There is no error reported, but create CLSID_CaptureGraphBuilder2 instance always failed in the machine. It's okay to create CLSID_FilterGraph. Before create CLSID_CaptureGraphBuilder2, I have called CoInitialize and created CLSID_FilterGraph. Only this machine has the error, what dll related with this interface or any function needed to call before to make it work? Thanks in advance.

  • Windows 7 Boot Loader - Remove 30 second waiting time

    - by derekhh
    I've installed Fedora 17 and Windows 7 on two different hard disks as a dual-boot system. The default boot loader is GRUB 2 maintained and configured in Fedora 17. When I startup and choose "Windows 7 bootloader (on /dev/sda1)" in GRUB 2, Windows 7 boot loader will appear, with only Windows 7 as the only choice and also the default operating system, with a 30 second waiting time if no input is detected. I'm trying to see if it is possible to remove this 30-second waiting time. I've tried to follow the instructions on the Web by configuring default operating system in the control panel but seems there is something wrong with it. I've also tried to use "bcdedit enum /all" but still receives error prompts. Update: Added my boot tab screen in msconfig.

  • Is it possible to write a Java printf statement that prints the statement itself?

    - by polygenelubricants
    Is it possible to have a Java printf statement, whose output is the statement itself? Some snippet to illustrate: // attempt #1 public class Main { public static void main(String[] args) { System.out.printf("something"); } } This prints something. So the output of attempt #1 is not quite exactly the printf statement in attempt #1. We can try something like this: // attempt #2 public class Main { public static void main(String[] args) { System.out.printf("System.out.printf(\"something\");"); } } And now the output is System.out.printf("something"); So now the output of attempt #2 matches the statement in output #1, but we're back to the problem we had before, since we need the output of attempt #2 to match the statement in attempt #2. So is it possible to write a one-line printf statement that prints itself?

    - by Nobik

When system going sleep and later waking up at scheduled time, my daemon do some work, and after it system should going sleep again. Now my questions: How can i detect, if the system was awaked by user or by the scheduled time? How can i detect, if a user currently working with the system, so the daemon have not to put it in sleep-mode??? Thanks Nobik

  • nUnit Assert.That(method,Throws.Exception) not catching exceptions

    - by JasonM
    Hi Everyone, Can someone tell me why this unit test that checks for exceptions fails? Obviously my real test is checking other code but I'm using Int32.Parse to show the issue. [Test] public void MyTest() { Assert.That(Int32.Parse("abc"), Throws.Exception.TypeOf<FormatException>()); } The test fails, giving this error. Obviously I'm trying to test for this exception and I think I'm missing something in my syntax. Error 1 TestCase '.MyTest' failed: System.FormatException : Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Int32.Parse(String s) based on the documentation at Throws Constraint (NUnit 2.5)
