  • GUI Freezes and Output to JTextField from user input

    - by user2929005
    I am having I hope only two issues currently. I have had help on this on a previous question that I have asked but now I am running into different issues. My current issues now is that I need to print out into a JTextField a sorted array. I do not have questions about how to sort the array I just would like help on how to get the array to print to the JTextField when the Bubble Sort button is pressed. Currently when I press the button it freezes. It freezes at this line. list.add(Integer.valueOf(input.nextInt())); please help Thank you. import java.awt.EventQueue; import javax.swing.*; import java.awt.event.*; import java.util.*; public class Sorting { private JFrame frame; private JTextArea inputArea; private JTextField outputArea; ArrayList<Integer> list = new ArrayList<Integer>(); Scanner input = new Scanner(System.in); /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { try { Sorting window = new Sorting(); window.frame.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } }); } /** * Create the application. */ public Sorting() { initialize(); } /** * Initialize the contents of the frame. */ private void initialize() { frame = new JFrame(); frame.setBounds(100, 100, 450, 300); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setTitle("Sorting"); frame.getContentPane().setLayout(null); JButton bubbleButton = new JButton("Bubble Sort"); bubbleButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { list.add(Integer.valueOf(input.nextInt())); // for(int i = 0; i < list.size(); i++){ // // } } }); bubbleButton.setBounds(10, 211, 114, 23); frame.getContentPane().add(bubbleButton); JButton mergeButton = new JButton("Merge Sort"); mergeButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { } }); mergeButton.setBounds(305, 211, 114, 23); frame.getContentPane().add(mergeButton); JButton quickButton = new JButton("Quick Sort"); quickButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { } }); quickButton.setBounds(163, 211, 114, 23); frame.getContentPane().add(quickButton); inputArea = new JTextArea(); inputArea.setBounds(10, 36, 414, 51); frame.getContentPane().add(inputArea); outputArea = new JTextField(); outputArea.setEditable(false); outputArea.setBounds(10, 98, 414, 59); frame.getContentPane().add(outputArea); outputArea.setColumns(10); JLabel label = new JLabel("Please Enter 5 Numbers"); label.setHorizontalAlignment(SwingConstants.CENTER); label.setBounds(10, 11, 414, 14); frame.getContentPane().add(label); } }

  • Java File I/O problems

    - by dwwilson66
    This is my first time working with file i/o in java, and it's not working. The section of the program where I parse individual lines and output a semicolon delimited line works like a charm when I hardcode a file and display on screen. Whne I try to write to a file public static OutputStream... errors out as an illegal start to expression, and I've been unable to get the program to step through an entire directory of files instead of one at a time. Where I'm not clear: I'm note setting an output filename anywhere...whare am I supposed to do that? The path variable won't pass. What's the proper format for a path? Can anyone see what I need to debug here? import java.io.*; public class FileRead { public static void main(String args[]) { try { // Open the file(s) // single file works OK FileInputStream fstream = new FileInputStream("testfile.txt"); Path startingDir = R:\Data\cs\RoboHelp\CorrLib\Output\Production\WebHelp; PrintFiles pf = new PrintFiles(); Files.walkFileTree(startingDir, pf); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String inputLine; String desc = ""; String docNo = ""; String replLtr = ""; String specCond = ""; String states = ""; String howGen = ""; String whenGen = ""; String owner = ""; String lastChange = ""; //Read File Line By Line while ((inputLine = br.readLine()) != null) { int testVal=0; int stringMax = inputLine.length(); // if(inputLine.startsWith("Description")) {desc = inputLine.substring(13,inputLine.length());} else if(inputLine.startsWith("Reference Number")) {docNo = inputLine.substring(20,inputLine.length());} else if(inputLine.startsWith("Replaces Letter")) {replLtr = inputLine.substring(17,inputLine.length());} else if(inputLine.startsWith("Special Conditions")) {specCond = inputLine.substring(21,inputLine.length());} else if(inputLine.startsWith("States Applicable")) {states = inputLine.substring(19,inputLine.length());} else if(inputLine.startsWith("How Generated")) {howGen = inputLine.substring(15,inputLine.length());} else if(inputLine.startsWith("When Generated")) {whenGen = inputLine.substring(16,inputLine.length());} else if(inputLine.startsWith("Owner")) {owner = inputLine.substring(7,inputLine.length());} else if(inputLine.startsWith("Last Change Date")) {lastChange = inputLine.substring(17,inputLine.length());} } //close while loop // Print the content on the console String outStr1 = (desc + ";" + docNo + ";" + replLtr + ";" + specCond + ";" + states); String outStr2 = (";" + howGen + ";" + whenGen + ";" + owner + ";" + lastChange); String outString = (outStr1 + outStr2); System.out.print(inputLine + "\n" + outString); String lineItem = (outStr1+outStr2); // try (OutputStream out = new BufferedOutputStream (logfile.newOutputStream(CREATE, APPEND))) { out.write(lineItem, 0, lineItem.length); } catch (IOException x) { System.err.println(x); } public static OutputStream newOutputStream() throws IOException { // append to an existing file, create file if it doesn't initially exist out = Files.newOutputStream(c:, CREATE, APPEND); } //Close the input stream in.close(); } catch (Exception e) { //Catch exception if any System.err.println("Error: " + e.getMessage()); } } }

  • Game logic dynamically extendable architecture implementation patterns

    - by Vlad
    When coding games there are a lot of cases when you need to inject your logic into existing class dynamically and without making unnecessary dependencies. For an example I have a Rabbit which can be affected by freeze ability so it can't jump. It could be implemented like this: class Rabbit { public bool CanJump { get; set; } void Jump() { if (!CanJump) return; ... } } But If I have more than one ability that can prevent it from jumping? I can't just set one property because some circumstances can be activated simultanously. Another solution? class Rabbit { public bool Frozen { get; set; } public bool InWater { get; set; } bool CanJump { get { return !Frozen && !InWater; } } } Bad. The Rabbit class can't know all the circumstances it can run into. Who knows what else will game designer want to add: may be an ability that changes gravity on an area? May be make a stack of bool values for CanJump property? No, because abilities can be deactivated not in that order in which they were activated. I need a way to seperate ability logic that prevent the Rabbit from jumping from the Rabbit itself. One possible solution for this is making special checking event: class Rabbit { class CheckJumpEventArgs : EventArgs { public bool Veto { get; set; } } public event EventHandler<CheckJumpEvent> OnCheckJump; void Jump() { var args = new CheckJumpEventArgs(); if (OnCheckJump != null) OnCheckJump(this, args); if (!args.Veto) return; ... } } But it's a lot of code! A real Rabbit class would have a lot of properties like this (health and speed attributes, etc). I'm thinking of borrowing something from MVVM pattern where you have all the properties and methods of an object implemented in a way where they can be easily extended from outside. Then I want to use it like this: class FreezeAbility { void ActivateAbility() { _rabbit.CanJump.Push(ReturnFalse); } void DeactivateAbility() { _rabbit.CanJump.Remove(ReturnFalse); } // should be implemented as instance member // so it can be "unsubscribed" bool ReturnFalse(bool previousValue) { return false; } } Is this approach good? What also should I consider? What are other suitable options and patterns? Any ready to use solutions? UPDATE The question is not about how to add different behaviors to an object dynamically but how its (or its behavior) implementation can be extended with external logic. I don't need to add a different behavior but I need a way to modify an exitsing one and I also need a possibiliity to undo changes.

  • SortCommand Event handler of DataGrid not working

    I have created an event handler for the OnSortCommand of DataGrid: <asp:DataGrid id="dtgBatches" runat="server" Width="100%" CssClass="intTable" EnableViewState="False" DataKeyField="bat_GUID" GridLines="Horizontal" AllowSorting="True" AutoGenerateColumns="False" AllowPaging="False" > <SelectedItemStyle BackColor="#FFFF99"></SelectedItemStyle> <AlternatingItemStyle CssClass="intTableEntry"></AlternatingItemStyle> <ItemStyle CssClass="intTableEntry2"></ItemStyle> <HeaderStyle ForeColor="Black" CssClass="tableHeader"></HeaderStyle> <Columns> <asp:TemplateColumn > <HeaderStyle Width="5%"></HeaderStyle> <ItemStyle HorizontalAlign="Center"></ItemStyle> <ItemTemplate> <img src="../images/icons/cog.png" onclick="universalAlert('Loading...',4,false); ViewBatch('<%# DataBinder.Eval(Container.DataItem, "bat_GUID") %>')" alt="view"/> </ItemTemplate> </asp:TemplateColumn> <asp:BoundColumn DataField="bat_Name" SortExpression="bat_Name" HeaderText="<%$ Resources:AI360Resource, lnkbtn_Name %>"> <HeaderStyle Width="10%"></HeaderStyle> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:BoundColumn> <asp:BoundColumn DataField="bat_Id" SortExpression="bat_Id" HeaderText="<%$ Resources:AI360Resource, ltxt_ID %>"> <HeaderStyle Width="10%"></HeaderStyle> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:BoundColumn> <asp:BoundColumn DataField="bat_Date" SortExpression="bat_Date" HeaderText="<%$ Resources:AI360Resource, alt_date %>" DataFormatString="{0:d}"> <HeaderStyle HorizontalAlign="right" Width="10%"></HeaderStyle> <ItemStyle HorizontalAlign="Right"></ItemStyle> </asp:BoundColumn> <asp:TemplateColumn> <HeaderStyle Width="1%"></HeaderStyle> </asp:TemplateColumn> <asp:BoundColumn DataField="bat_Close_date" SortExpression="bat_Close_date" HeaderText="<%$ Resources:AI360Resource, ltxt_closed %>" DataFormatString="{0:d}"> <HeaderStyle Width="29%"></HeaderStyle> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:BoundColumn> <asp:BoundColumn DataField="bat_Cont_Amount" SortExpression="bat_Cont_Amount" HeaderText="<%$ Resources:AI360Resource, alt_receipts %>" DataFormatString="{0:c}"> <HeaderStyle Width="10%"></HeaderStyle> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:BoundColumn> <asp:BoundColumn DataField="bat_Disb_Amount" SortExpression="bat_Disb_Amount" HeaderText="<%$ Resources:AI360Resource, alt_disb %>" DataFormatString="{0:c}"> <HeaderStyle Width="25%"></HeaderStyle> <ItemStyle HorizontalAlign="Left"></ItemStyle> </asp:BoundColumn> </Columns> </asp:DataGrid> And the code of handler is as below: protected void dtgBatches_SortCommand(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e) { string strCurrentSort = dtgBatches.Attributes["SortExpr"]; string strNewSort = e.SortExpression; if ((strCurrentSort != null) && (strCurrentSort == strNewSort)) { //reverse direction strNewSort += " DESC"; } // Code to Set DataView dv dv.Sort = strNewSort; dtgBatches.DataSource = dv; dtgBatches.DataBind(); } The problem is that the handler never executes. The registartion for the handler is done as below: private void InitializeComponent() { this.dtgBatches.SortCommand += new System.Web.UI.WebControls.DataGridSortCommandEventHandler(this.dtgBatches_SortCommand); }

  • How to generalize a method call in Java (to avoid code duplication)

    - by dln385
    I have a process that needs to call a method and return its value. However, there are several different methods that this process may need to call, depending on the situation. If I could pass the method and its arguments to the process (like in Python), then this would be no problem. However, I don't know of any way to do this in Java. Here's a concrete example. (This example uses Apache ZooKeeper, but you don't need to know anything about ZooKeeper to understand the example.) The ZooKeeper object has several methods that will fail if the network goes down. In this case, I always want to retry the method. To make this easy, I made a "BetterZooKeeper" class that inherits the ZooKeeper class, and all of its methods automatically retry on failure. This is what the code looked like: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(String path, Watcher watcher) { while (true) { try { return super.exists(path, watcher); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public byte[] getData(String path, boolean watch, Stat stat) { while (true) { try { return super.getData(path, watch, stat); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public void delete(String path, int version) { while (true) { try { super.delete(path, version); return; } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } (In the actual program there is much more logic and many more methods that I took out of the example for simplicity.) We can see that I'm using the same retry logic, but the arguments, method call, and return type are all different for each of the methods. Here's what I did to eliminate the duplication of code: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(final String path, final Watcher watcher) { return new RetryableZooKeeperAction<Stat>() { @Override public Stat action() { return BetterZooKeeper.super.exists(path, watcher); } }.run(); } @Override public byte[] getData(final String path, final boolean watch, final Stat stat) { return new RetryableZooKeeperAction<byte[]>() { @Override public byte[] action() { return BetterZooKeeper.super.getData(path, watch, stat); } }.run(); } @Override public void delete(final String path, final int version) { new RetryableZooKeeperAction<Object>() { @Override public Object action() { BetterZooKeeper.super.delete(path, version); return null; } }.run(); return; } private abstract class RetryableZooKeeperAction<T> { public abstract T action(); public final T run() { while (true) { try { return action(); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } } The RetryableZooKeeperAction is parameterized with the return type of the function. The run() method holds the retry logic, and the action() method is a placeholder for whichever ZooKeeper method needs to be run. Each of the public methods of BetterZooKeeper instantiates an anonymous inner class that is a subclass of the RetryableZooKeeperAction inner class, and it overrides the action() method. The local variables are (strangely enough) implicitly passed to the action() method, which is possible because they are final. In the end, this approach does work and it does eliminate the duplication of the retry logic. However, it has two major drawbacks: (1) it creates a new object every time a method is called, and (2) it's ugly and hardly readable. Also I had to workaround the 'delete' method which has a void return value. So, here is my question: is there a better way to do this in Java? This can't be a totally uncommon task, and other languages (like Python) make it easier by allowing methods to be passed. I suspect there might be a way to do this through reflection, but I haven't been able to wrap my head around it.

  • Why is my NSURLConnection so slow?

    - by Bama91
    I have setup an NSURLConnection using the guidelines in Using NSURLConnection from the Mac OS X Reference Library, creating an NSMutableURLRequest as POST to a PHP script with a custom body to upload 20 MB of data (see code below). Note that the post body is what it is (line breaks and all) to exactly match an existing desktop implementation. When I run this in the iPhone simulator, the post is successful, but takes an order of magnitude longer than if I run the equivalent code locally on my Mac in C++ (20 minutes vs. 20 seconds, respectively). Any ideas why the difference is so dramatic? I understand that the simulator will give different results than the actual device, but I would expect at least similar results. Thanks const NSUInteger kDataSizePOST = 20971520; const NSString* kServerBDC = @"WWW.SOMEURL.COM"; const NSString* kUploadURL = @"http://WWW.SOMEURL.COM/php/test/upload.php"; const NSString* kUploadFilename = @"test.data"; const NSString* kUsername = @"testuser"; const NSString* kHostname = @"testhost"; srandom(time(NULL)); NSMutableData *uniqueData = [[NSMutableData alloc] initWithCapacity:kDataSizePOST]; for (unsigned int i = 0 ; i < kDataSizePOST ; ++i) { u_int32_t randomByte = ((random() % 95) + 32); [uniqueData appendBytes:(void*)&randomByte length:1]; } NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:kUploadURL]]; [request setHTTPMethod:@"POST"]; NSString *boundary = @"aBcDd"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *postbody = [NSMutableData data]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[uniqueData length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: form-data; name=test; filename=%@", kUploadFilename] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithString:@";\nContent-Type: multipart/mixed;\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[NSData dataWithData:uniqueData]]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[kUsername length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: inline; name=Username;\n\r\n%@",kUsername] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"--%@\nContent-Size:%d",boundary,[kHostname length]] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\nContent-Disposition: inline; name=Hostname;\n\r\n%@",kHostname] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"\n--%@--",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:postbody]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (theConnection) { _receivedData = [[NSMutableData data] retain]; } else { // Inform the user that the connection failed. } [request release]; [uniqueData release];

I am getting problem in this i posted my code below. send.c /*filename : send.c *To compile : gcc send.c -o send */ #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <string.h> #include <sys/types.h> #include <sys/ipc.h> #include <sys/msg.h> struct my_msgbuf { long mtype; char *mtext; }; int main(void) { struct my_msgbuf buf; int msqid; key_t key; static int count = 0; char temp[5]; int run = 1; if ((key = ftok("send.c", 'B')) == -1) { perror("ftok"); exit(1); } printf("send.c Key is = %d\n",key); if ((msqid = msgget(key, 0644 | IPC_CREAT)) == -1) { perror("msgget"); exit(1); } printf("Enter lines of text, ^D to quit:\n"); buf.mtype = 1; /* we don't really care in this case */ int ret = -1; while(run) { count++; buf.mtext = malloc(50); strcpy(buf.mtext,"Hi hello test message here"); snprintf(temp, sizeof (temp), "%d",count); strcat(buf.mtext,temp); int len = strlen(buf.mtext); /* ditch newline at end, if it exists */ if (buf.mtext[len-1] == '\n') buf.mtext[len-1] = '\0'; if (msgsnd(msqid, &buf, len+1, IPC_NOWAIT) == -1) /* +1 for '\0' */ perror("msgsnd"); if(count == 100) run = 0; usleep(1000000); } if (msgctl(msqid, IPC_RMID, NULL) == -1) { perror("msgctl"); exit(1); } return 0; } receive.c /* filename : receive.c * To compile : gcc receive.c -o receive */ #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <sys/types.h> #include <sys/ipc.h> #include <sys/msg.h> struct my_msgbuf { long mtype; char *mtext; }; int main(void) { struct my_msgbuf buf; int msqid; key_t key; if ((key = ftok("send.c", 'B')) == -1) { /* same key as send.c */ perror("ftok"); exit(1); } if ((msqid = msgget(key, 0644)) == -1) { /* connect to the queue */ perror("msgget"); exit(1); } printf("test: ready to receive messages, captain.\n"); for(;;) { /* receive never quits! */ buf.mtext = malloc(50); if (msgrcv(msqid, &buf, 50, 0, 0) == -1) { perror("msgrcv"); exit(1); } printf("test: \"%s\"\n", buf.mtext); } return 0; }

  • SqlDataAdapter Update is not working in C# wih Sql Server

    - by Ahmed
    I am trying to save data from C# form to Sql server Northwind Orders database, I am only using CustomerID, OrderDate and ShippedDate for data entry.

  • Mbean registered but not found in mbean Server

    - by Prisco
    I have a problem about the mbeans. I have created a simple mbean and I have registered it on the default mBeanServer that is run (Via eclipse or java -jar mbean.jar) and in the same process if I try to fouund the mbean registered with a simple query: for (ObjectInstance instance : mbs.queryMBeans(ObjectNameMbean, null)) { System.out.println(instance.toString()); } the query retuerns my mbean, but if I start another process and try to search this mbean registered the mbeas is not found! why? The approch is : (Process that is running) public static void main(String[] args) throws Exception { MBeanServer mbeanServer =ManagementFactory.getPlatformMBeanServer(); ObjectName objectName = new ObjectName(ObjectNameMbean); Simple simple = new Simple (1, 0); mbeanServer.registerMBean(simple, objectName); while (true) { wait (Is this necessary?) } } So this is the first process that is running (that has the only pourpose to registry the mbean, because there is another process that want to read these informations. So I start another process to search this mbean but nothing. I 'm not using jboss but the local Java virtual Machine but my scope is to deploy this simple application in one ejb (autostart) and another ejb will read all informations. All suggestions are really apprecciated. This example should be more useful : Object Hello: public class Hello implements HelloMBean { public void sayHello() { System.out.println("hello, world"); } public int add(int x, int y) { return x + y; } public String getName() { return this.name; } public int getCacheSize() { return this.cacheSize; } public synchronized void setCacheSize(int size) { this.cacheSize = size; System.out.println("Cache size now " + this.cacheSize); } private final String name = "Reginald"; private int cacheSize = DEFAULT_CACHE_SIZE; private static final int DEFAULT_CACHE_SIZE = 200; } Interface HelloBean (implemented by Hello) public interface HelloMBean { public void sayHello(); public int add(int x, int y); public String getName(); public int getCacheSize(); public void setCacheSize(int size); } Simple Main import java.lang.management.ManagementFactory; import java.util.logging.Logger; import javax.management.MBeanServer; import javax.management.ObjectName; public class Main { static Logger aLog = Logger.getLogger("MBeanTest"); public static void main(String[] args) { try{ MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName name = new ObjectName("ApplicationDomain:type=Hello"); Hello mbean = new Hello(); mbs.registerMBean(mbean, name); // System.out.println(mbs.getAttribute(name, "Name")); aLog.info("Waiting forever..."); Thread.sleep(Long.MAX_VALUE); } catch(Exception x){ x.printStackTrace(); aLog.info("exception"); } } } So now I have exported this project as jar file and run it as "java -jar helloBean.jar" and by eclipse I have modified the main class to read informations of this read (Example "Name" attribute) by using the same objectname used to registry it . Main to read : public static void main(String[] args) { try{ MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName name = new ObjectName("ApplicationDomain:type=Hello"); System.out.println(mbs.getAttribute(name, "Name")); } catch(Exception x){ x.printStackTrace(); aLog.info("exception"); } } But nothing, the bean is not found.

  • Performance issues with repeatable loops as control part

    - by djerry
    Hey guys, In my application, i need to show made calls to the user. The user can arrange some filters, according to what they want to see. The problem is that i find it quite hard to filter the calls without losing performance. This is what i am using now : private void ProcessFilterChoice() { _filteredCalls = ServiceConnector.ServiceConnector.SingletonServiceConnector.Proxy.GetAllCalls().ToList(); if (cboOutgoingIncoming.SelectedIndex > -1) GetFilterPartOutgoingIncoming(); if (cboInternExtern.SelectedIndex > -1) GetFilterPartInternExtern(); if (cboDateFilter.SelectedIndex > -1) GetFilteredCallsByDate(); wbPdf.Source = null; btnPrint.Content = "Pdf preview"; } private void GetFilterPartOutgoingIncoming() { if (cboOutgoingIncoming.SelectedItem.ToString().Equals("Outgoing")) for (int i = _filteredCalls.Count - 1; i > -1; i--) { if (_filteredCalls[i].Caller.E164.Length > 4 || _filteredCalls[i].Caller.E164.Equals("0")) _filteredCalls.RemoveAt(i); } else if (cboOutgoingIncoming.SelectedItem.ToString().Equals("Incoming")) for (int i = _filteredCalls.Count - 1; i > -1; i--) { if (_filteredCalls[i].Called.E164.Length > 4 || _filteredCalls[i].Called.E164.Equals("0")) _filteredCalls.RemoveAt(i); } } private void GetFilterPartInternExtern() { if (cboInternExtern.SelectedItem.ToString().Equals("Intern")) for (int i = _filteredCalls.Count - 1; i > -1; i--) { if (_filteredCalls[i].Called.E164.Length > 4 || _filteredCalls[i].Caller.E164.Length > 4 || _filteredCalls[i].Caller.E164.Equals("0")) _filteredCalls.RemoveAt(i); } else if (cboInternExtern.SelectedItem.ToString().Equals("Extern")) for (int i = _filteredCalls.Count - 1; i > -1; i--) { if ((_filteredCalls[i].Called.E164.Length < 5 && _filteredCalls[i].Caller.E164.Length < 5) || _filteredCalls[i].Called.E164.Equals("0")) _filteredCalls.RemoveAt(i); } } private void GetFilteredCallsByDate() { DateTime period = DateTime.Now; switch (cboDateFilter.SelectedItem.ToString()) { case "Today": period = DateTime.Today; break; case "Last week": period = DateTime.Today.Subtract(new TimeSpan(7, 0, 0, 0)); break; case "Last month": period = DateTime.Today.AddMonths(-1); break; case "Last year": period = DateTime.Today.AddYears(-1); break; default: return; } for (int i = _filteredCalls.Count - 1; i > -1; i--) { if (_filteredCalls[i].Start < period) _filteredCalls.RemoveAt(i); } } _filtered calls is a list of "calls". Calls is a class that looks like this : [DataContract] public class Call { private User caller, called; private DateTime start, end; private string conferenceId; private int id; private bool isNew = false; [DataMember] public bool IsNew { get { return isNew; } set { isNew = value; } } [DataMember] public int Id { get { return id; } set { id = value; } } [DataMember] public string ConferenceId { get { return conferenceId; } set { conferenceId = value; } } [DataMember] public DateTime End { get { return end; } set { end = value; } } [DataMember] public DateTime Start { get { return start; } set { start = value; } } [DataMember] public User Called { get { return called; } set { called = value; } } [DataMember] public User Caller { get { return caller; } set { caller = value; } } Can anyone direct me to a better solution or make some suggestions.

  • "didChangeSection:" NSfetchedResultsController delegate method not being called

    - by robenk
    I have a standard split view controller, with a detail view and a table view. Pressing a button in the detail view can cause the an object to change its placement in the table view's ordering. This works fine, as long as the resulting ordering change doesn't result in a section being added or removed. I.e. an object can change it's ordering in a section or switch from one section to another. Those ordering changes work correctly without problems. But, if the object tries to move to a section that doesn't exist yet, or is the last object to leave a section (therefore requiring the section its leaving to be removed), then the application crashes. NSFetchedResultsControllerDelegate has methods to handle sections being added and removed that should be called in those cases. But those delegate methods aren't being called for some reason. The code in question, is boilerplate: - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { NSLog(@"willChangeContent"); [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { NSLog(@"didChangeSection"); switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { NSLog(@"didChangeObject"); UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self configureCell:[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath]withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { NSLog(@"didChangeContent"); [self.tableView endUpdates]; [detailViewController.reminderView update]; } Starting the application, and then causing the last object to leave a section results in the following output: 2011-01-08 23:40:18.910 Reminders[54647:207] willChangeContent 2011-01-08 23:40:18.912 Reminders[54647:207] didChangeObject 2011-01-08 23:40:18.914 Reminders[54647:207] didChangeContent 2011-01-08 23:40:18.915 Reminders[54647:207] *** Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-1145.66/UITableView.m:825 2011-01-08 23:40:18.917 Reminders[54647:207] Serious application error.

The number of sections contained in the table view after the update (5) must be equal to the number of sections contained in the table view before the update (6), plus or minus the number of sections inserted or deleted (0 inserted, 0 deleted). with userInfo (null) As you can see, "willChangeContent", "didChangeObject" (moving the object in question), and "didChangeContent" were all called properly. Based on the Apple's NSFetchedResultsControllerDelegate documentation "didChangeSection" should have been called before "didChangeObject", which would have prevented the exception causing the crash. So I guess the question is how do I assure that didChangeSection gets called? Thanks in advance for any help!

  • Learning to implement DIC in MVC

    - by Tom
    I am learning to apply DIC to MVC project. So, I have sketched this DDD-ish DIC-ready-ish layout to my best understanding. I have read many blogs articles wikis for the last few days. However, I am not confident about implementing it correctly. Could you please demonstrate to me how to put them into DIC the proper way? I prefer Ninject or Windsor after all the readings, but anyDIC will do as long as I can get the correct idea how to do it. Web controller... public class AccountBriefingController { //create private IAccountServices accountServices { get; set; } public AccountBriefingController(IAccountServices accsrv) accountServices = accsrv; } //do work public ActionResult AccountBriefing(string userid, int days) { //get days of transaction records for this user BriefingViewModel model = AccountServices.GetBriefing(userid, days); return View(model); } } View model ... public class BriefingViewModel { //from user repository public string UserId { get; set; } public string AccountNumber {get; set;} public string FirstName { get; set; } public string LastName { get; set; } //from account repository public string Credits { get; set; } public List<string> Transactions { get; set; } } Service layer ... public interface IAccountServices { BriefingViewModel GetBriefing(); } public class AccountServices { //create private IUserRepository userRepo {get; set;} private IAccountRepository accRepo {get; set;} public AccountServices(UserRepository ur, AccountRepository ar) { userRepo = ur; accRepo = ar; } //do work public BriefingViewModel GetBriefing(string userid, int days) { var model = new BriefingViewModel(); //<---is that okay to new a model here?? var user = userRepo.GetUser(userid); if(user != null) { model.UserId = userid; model.AccountNumber = user.AccountNumber; model.FirstName = user.FirstName; model.LastName = user.LastName; //account records model.Credits = accRepo.GetUserCredits(userid); model.Transactions = accRepo.GetUserTransactions(userid, days); } return model; } } Domain layer and data models... public interface IUserRepository { UserDataModel GetUser(userid); } public interface IAccountRepository { List<string> GetUserTransactions(userid, days); int GetUserCredits(userid); } // Entity Framework DBContext goes under here Please point out if my implementation is wrong, e.g.I can feel in AccountServices-GetBriefing - new BriefingViewModel() seems wrong to me, but I don't know how to fit the stud into DIC? Thank you very much for your help!

  • How do I detect a file write error in C?

    - by rich
    I have an embedded environment where a user might insert or remove a USB flash drive. I would like to know if the drive has been removed, or if there is some other problem when I try to write to the drive. However, Linux just saves the information in its buffers and returns with no indicated error. The computer I'm using comes with a 2.4.26 kernel and libc 2.3.2. I'm mounting the drive this way: i = mount(MEMORY_DEV_PATH, MEMORY_MNT_PATH, "vfat", MS_SYNCHRONOUS, NULL); That works: 50:/root # mount /dev/scsi/host0/bus0/target0/lun0/part1 on /mem type vfat (rw,sync) 50:/root # Later, I try to copy a file to it: int ifile, ofile; ifile = open("/tmp/tmpmidi.mid", O_RDONLY); if (ifile < 0) { perror("open in"); break; } ofile = open(current_file_name.c_str(), O_WRONLY | O_SYNC); if (ofile < 0) { perror("open out"); break; } #define BUFSZ 256 char buffer[BUFSZ]; while (1) { i = read(ifile, buffer, BUFSZ); if (i < 0) { perror("read"); break; } j = write(ofile, buffer, i); if (j < 0) { perror("write"); break; } if (i != j) { perror("Sizes wrong"); break; } if (i < BUFSZ) { printf("Copy is finished, I hope\n"); close(ifile); close(ofile); break; } } If this snippet of code is executed with a write-protected USB memory, the result is Copy is finished, I hope amid a flurry of error messages from the kernel on the console. I believe the same thing would happen if I simply removed the USB drive (without unmounting it). I have also fiddled with devfs. I figured out how to get it to automatically mount the drive, (with the REGISTER event) but it never seems to trigger the UNREGISTER when I pull out the memory. How can I determine in my program whether I have successfully created a file? Update 4 July: It was a silly oversight of me not to check the result from close(). Unfortunately, the file can be closed without error. So that didn't help. What about fsync()? That sounds like a good idea, but that didn't catch the error either. There might be some interesting information in /sys if I had such a thing. I believe that didn't get added until 2.6.?. The comment(s) about the quality of my flash drive are probably justified. It's one of the earlier ones. In fact, write protect switches seem to be extremely rare these days. I think I have to use the overkill option: Create a file, unmount & remount the drive, and check to see if the file is there. If that doesn't solve my problem, then something is really messed up! Note to myself: Make sure the file you try to create isn't already there! By the way, this does happen to be a C++ program. You can tell by the .c_str() which I had intended to edit out for simplicity.

  • AsyncTask, inner classes and Buttons states

    - by Intern John Smith
    For a musical application (a sequencer), I have a few buttons static ArrayList<Button> Buttonlist = new ArrayList<Button>(); Buttonlist.add(0,(Button) findViewById(R.id.case_kick1)); Buttonlist.add(1,(Button) findViewById(R.id.case_kick2)); Buttonlist.add(2,(Button) findViewById(R.id.case_kick3)); Buttonlist.add(3,(Button) findViewById(R.id.case_kick4)); Buttonlist.add(4,(Button) findViewById(R.id.case_kick5)); Buttonlist.add(5,(Button) findViewById(R.id.case_kick6)); Buttonlist.add(6,(Button) findViewById(R.id.case_kick7)); Buttonlist.add(7,(Button) findViewById(R.id.case_kick8)); that I activate through onClickListeners with for example Buttonlist.get(0).setActivated(true); I played the activated sound via a loop and ifs : if (Buttonlist.get(k).isActivated()) {mSoundManager.playSound(1); Thread.sleep(250);} The app played fine but I couldn't access the play/pause button when it was playing : I searched and found out about AsyncTasks. I have a nested class PlayPause : class PlayPause extends AsyncTask<ArrayList<Button>,Integer,Void> in which I have this : protected Void doInBackground(ArrayList<Button>... params) { for(int k=0;k<8;k++) { boolean isPlayed = false; if (Buttonlist.get(k).isActivated()) { mSoundManager.playSound(1); isPlayed = true; try {Thread.sleep(250); } catch (InterruptedException e) {e.printStackTrace();}} if(!isPlayed){ try {Thread.sleep(250);} catch (InterruptedException e) {e.printStackTrace();} } } return null; } I launch it via Play.setOnClickListener(new PlayClickListener()); with PlayClickListener : public class PlayClickListener implements OnClickListener { private Tutorial acti; public PlayClickListener(){ super(); } @SuppressWarnings("unchecked") public void onClick(View v) { if(Tutorial.play==0){ Tutorial.play=1; Tutorial.Play.setBackgroundResource(R.drawable.action_down); acti = new Tutorial(); Tutorial.PlayPause myPlayPause = acti.new PlayPause(); myLecture.execute(Tutorial.Buttonlist); } else { Tutorial.play=0; Tutorial.lecture.cancel(true); Tutorial.Play.setBackgroundResource(R.drawable.action); } } } But it doesn't work. when I click on buttons and I touch Play/Pause, I have this : 07-02 11:06:01.350: E/AndroidRuntime(7883): FATAL EXCEPTION: AsyncTask #1 07-02 11:06:01.350: E/AndroidRuntime(7883): Caused by: java.lang.NullPointerException 07-02 11:06:01.350: E/AndroidRuntime(7883): at com.Tutorial.Tutorial$PlayPause.doInBackground(Tutorial.java:603) 07-02 11:06:01.350: E/AndroidRuntime(7883): at com.Tutorial.Tutorial$PlayPause.doInBackground(Tutorial.java:1) And I don't know how to get rid of this error. Obviously, the Asynctask doesn't find the Buttonlist activated status, even if the list is static. I don't know how to access these buttons' states, isPressed doesn't work either. Thanks for reading and helping me !

  • iphone web service access

    - by malleswar
    Hi, I have .net webservice methods login and summary. After getting the result from login, I need to show second view and need to call summary method. I am following this tutorial. http://icodeblog.com/2008/11/03/iphone-programming-tutorial-intro-to-soap-web-services/ I created two new classes loginaccess.h and loginaccess.m. @implementation LoginAccess @synthesize ResultString,webData, soapResults, xmlParser; -(NSString*)LoginCheck:(NSString*)userName:(NSString*)pwd { NSString *soapMessage = [NSString stringWithFormat: @"\n" "\n" "\n" "\n" "%@" "%@" "" "\n" "\n",userName,pwd ]; NSLog(soapMessage); NSURL *url = [NSURL URLWithString:@"http://www.XXXXXXXXX.com/service.asmx"]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue: @"http://XXXXXXXXm/Login" forHTTPHeaderField:@"SOAPAction"]; [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; [theRequest setHTTPMethod:@"POST"]; [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if( theConnection ) { webData = [[NSMutableData data] retain]; } else { NSLog(@"theConnection is NULL"); } //[nameInput resignFirstResponder]; return ResultString; } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [webData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [webData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"ERROR with theConenction"); [connection release]; [webData release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"DONE. Received Bytes: %d", [webData length]); NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; NSLog(theXML); [theXML release]; if( xmlParser ) { [xmlParser release]; } xmlParser = [[NSXMLParser alloc] initWithData: webData]; [xmlParser setDelegate: self]; [xmlParser setShouldResolveExternalEntities: YES]; [xmlParser parse]; [connection release]; [webData release]; } -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName attributes: (NSDictionary *)attributeDict { if( [elementName isEqualToString:@"LoginResult"]) { if(!soapResults) { soapResults = [[NSMutableString alloc] init]; } recordResults = TRUE; } } -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if( recordResults ) { [soapResults appendString: string]; } } -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if( [elementName isEqualToString:@"LoginResult"]) { recordResults = FALSE; ResultString = soapResults; NSLog(@"Login"); [VariableStore setStr:ResultString]; NSLog(soapResults); [soapResults release]; soapResults = nil; } } @end I am calling LoginCheck method and based on result I want to show the second view. Here after finishing of the button touch down event, it enter into did end element, so I am always getting nil value. If I use the same code controller it works fine as I push second view controller in didendelement. Please give me some samples to place the web service calls in differnt class and how to call them in viewcontrollers. Regards, Malleswar

  • Visual Studio reports that not all code path return a value, even though they do

    - by chris12892
    I have an API in NETMF C# that I am writing that includes a function to send an HTTP request. For those who are familiar with NETMF, this is a heavily modified version of the "webClient" example, which a simple application that demonstrates how to submit an HTTP request, and recive a response. In the sample, it simply prints the response and returns void,. In my version, however, I need it to return the HTTP response. For some reason, Visual Studio reports that not all code paths return a value, even though, as far as I can tell, they do. Here is my code... /// <summary> /// This is a modified webClient /// </summary> /// <param name="url"></param> private string httpRequest(string url) { // Create an HTTP Web request. HttpWebRequest request = HttpWebRequest.Create(url) as HttpWebRequest; // Set request.KeepAlive to use a persistent connection. request.KeepAlive = true; // Get a response from the server. WebResponse resp = request.GetResponse(); // Get the network response stream to read the page data. if (resp != null) { Stream respStream = resp.GetResponseStream(); string page = ""; byte[] byteData = new byte[4096]; char[] charData = new char[4096]; int bytesRead = 0; Decoder UTF8decoder = System.Text.Encoding.UTF8.GetDecoder(); int totalBytes = 0; // allow 5 seconds for reading the stream respStream.ReadTimeout = 5000; // If we know the content length, read exactly that amount of // data; otherwise, read until there is nothing left to read. if (resp.ContentLength != -1) { for (int dataRem = (int)resp.ContentLength; dataRem > 0; ) { Thread.Sleep(500); bytesRead = respStream.Read(byteData, 0, byteData.Length); if (bytesRead == 0) throw new Exception("Data laes than expected"); dataRem -= bytesRead; // Convert from bytes to chars, and add to the page // string. int byteUsed, charUsed; bool completed = false; totalBytes += bytesRead; UTF8decoder.Convert(byteData, 0, bytesRead, charData, 0, bytesRead, true, out byteUsed, out charUsed, out completed); page = page + new String(charData, 0, charUsed); } page = new String(System.Text.Encoding.UTF8.GetChars(byteData)); } else throw new Exception("No content-Length reported"); // Close the response stream. For Keep-Alive streams, the // stream will remain open and will be pushed into the unused // stream list. resp.Close(); return page; } } Any ideas? Thanks...
