  • Trying to sentinel loop this program. [java]

    - by roger34
    Okay, I spent all this time making this for class but I have one thing that I can't quite get: I need this to sentinel loop continuously (exiting upon entering x) so that the System.out.println("What type of Employee? Enter 'o' for Office " + "Clerical, 'f' for Factory, or 's' for Saleperson. Enter 'x' to exit." ); line comes back up after they enter the first round of information. Also, I can't leave this up long on the (very) off chance a classmate might see this and steal the code. Full code following: import java.util.Scanner; public class Project1 { public static void main (String args[]){ Scanner inp = new Scanner( System.in ); double totalPay; System.out.println("What type of Employee? Enter 'o' for Office " + "Clerical, 'f' for Factory, or 's' for Saleperson. Enter 'x' to exit." ); String response= inp.nextLine(); while (!response.toLowerCase().equals("o")&&!response.toLowerCase().equals("f") &&!response.toLowerCase().equals("s")&&!response.toLowerCase().equals("x")){ System.out.print("\nInvalid selection,please enter your choice again:\n"); response=inp.nextLine(); } char choice = response.toLowerCase().charAt( 0 ); switch (choice){ case 'o': System.out.println("Enter your hourly rate:"); double officeRate=inp.nextDouble(); System.out.println("Enter the number of hours worked:"); double officeHours=inp.nextDouble(); totalPay = officeCalc(officeRate,officeHours); taxCalc(totalPay); break; case 'f': System.out.println("How many Widgets did you produce during the week?"); double widgets=inp.nextDouble(); totalPay=factoryCalc(widgets); taxCalc(totalPay); break; case 's': System.out.println("What were your total sales for the week?"); double totalSales=inp.nextDouble(); totalPay=salesCalc(totalSales); taxCalc(totalPay); break; } } public static double taxCalc(double totalPay){ double federal=totalPay*.22; double state =totalPay*.055; double netPay = totalPay - federal - state; federal =federal*Math.pow(10,2); federal =Math.round(federal); federal= federal/Math.pow(10,2); state =state*Math.pow(10,2); state =Math.round(state); state= state/Math.pow(10,2); totalPay =totalPay*Math.pow(10,2); totalPay =Math.round(totalPay); totalPay= totalPay/Math.pow(10,2); netPay =netPay*Math.pow(10,2); netPay =Math.round(netPay); netPay= netPay/Math.pow(10,2); System.out.printf("\nTotal Pay \t: %1$.2f.\n", totalPay); System.out.printf("State W/H \t: %1$.2f.\n", state); System.out.printf("Federal W/H : %1$.2f.\n", federal); System.out.printf("Net Pay \t: %1$.2f.\n", netPay); return totalPay; } public static double officeCalc(double officeRate,double officeHours){ double overtime=0; if (officeHours>=40) overtime = officeHours-40; else overtime = 0; if (officeHours >= 40) officeHours = 40; double otRate = officeRate * 1.5; double totalPay= (officeRate * officeHours) + (otRate*overtime); return totalPay; } public static double factoryCalc(double widgets){ double totalPay=widgets*.35 +300; return totalPay; } public static double salesCalc(double totalSales){ double totalPay = totalSales * .05 + 500; return totalPay; } }

  • wpf custom control problem

    - by josika
    Hi! I have a problem, and I have not found the solution yet. I woud like to create a base custom control and use it in another custom control. The base control work fine when I use in a window, but when I use in the other custom control, the binding does not work. What's wrong with my code? Code: Model: public class ElementModel { public string Name { get; set; } public string FullName { get; set; } } The base control: public class ListControl : Control { static ListControl() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ListControl), new FrameworkPropertyMetadata(typeof(ListControl))); } public ListControl() { SetValue(ElementListProperty, new List<ElementModel>()); } public static readonly DependencyProperty ElementListProperty = DependencyProperty.Register( "ElementList", typeof(List<ElementModel>), typeof(ListControl), new FrameworkPropertyMetadata(new List<ElementModel>()) ); public List<ElementModel> ElementList { get { return (List<ElementModel>)GetValue(ElementListProperty); } set { SetValue(ElementListProperty, value); } } } The Wrapper Control: public class ListWrapper : Control { static ListWrapper() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ListWrapper), new FrameworkPropertyMetadata(typeof(ListWrapper))); } public ListWrapper() { SetValue(EMListProperty, new List<ElementModel>()); } public static readonly DependencyProperty EMListProperty = DependencyProperty.Register( "EMList", typeof(List<ElementModel>), typeof(ListWrapper), new FrameworkPropertyMetadata(new List<ElementModel>()) ); public List<ElementModel> EMList { get { return (List<ElementModel>)GetValue(EMListProperty); } set { SetValue(EMListProperty, value); } } } Generic.xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:UIControl"> <Style TargetType="{x:Type local:ListControl}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListControl}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <ListBox ItemsSource="{TemplateBinding ElementList}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Label Content="Name:"/> <TextBlock Text="{Binding Path=Name}" /> <Label Content="Full name:"/> <TextBlock Text="{Binding Path=FullName}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="{x:Type local:ListWrapper}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListWrapper}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <local:ListControl ElementList="{TemplateBinding EMList}" /> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> If I put the controls in the window and binding properties, than the ListControl works fine and shows the elements, but the WrapperList does not. <Window x:Class="MainApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ui="clr-namespace:UIControl;assembly=UIControl" Title="Window1" Height="304" Width="628"> <Grid> <ui:ListControl x:Name="listCtr" ElementList="{Binding Path=EList}" HorizontalAlignment="Left" Width="300" /> <ui:ListWrapper x:Name="listWrp" EMList="{Binding Path=EList}" HorizontalAlignment="Right" Width="300" Background="Gray"/> </Grid> Project archive

  • Java SWT - placing image buttons on the image background

    - by foma
    I am trying to put buttons with images(gif) on the background which has already been set as an image (shell.setBackgroundImage(image)) and I can't figure out how to remove transparent border around buttons with images. I would be grateful if somebody could give me some tip about this issue. Here is my code: import org.eclipse.swt.widgets.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.*; import org.eclipse.swt.graphics.*; public class Main_page { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Image image = new Image(display, "bg.gif"); shell.setBackgroundImage(image); shell.setBackgroundMode(SWT.INHERIT_DEFAULT); shell.setFullScreen(true); Button button = new Button(shell, SWT.PUSH); button.setImage(new Image(display, "button.gif")); RowLayout Layout = new RowLayout(); shell.setLayout(Layout); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } } Sorceror, thanks for your answer I will definitely look into this article. Maybe I will find my way. So far I have improved my code a little bit. Firstly, I managed to get rid of the gray background noise. Secondly, I finally succeeded in creating the button as I had seen it in the first place. Yet, another obstacle has arisen. When I removed image(button) transparent border it turned out that the button change its mode(from push button to check box). The problem is that I came so close to the thing I was looking for and now I am a little puzzled. If you have some time please give a glance at my code. Here is the code, if you launch it you will see what the problem is(hope you didn't have problems downloading images): import org.eclipse.swt.widgets.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.*; import org.eclipse.swt.graphics.*; public class Main_page { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Image image = new Image(display, "bg.gif"); // Launch on a screen 1280x1024 shell.setBackgroundImage(image); shell.setBackgroundMode(SWT.TRANSPARENT); shell.setFullScreen(true); GridLayout gridLayout = new GridLayout(); gridLayout.marginTop = 200; gridLayout.marginLeft = 20; shell.setLayout(gridLayout); // If you replace SWT.PUSH with SWT.COLOR_TITLE_INACTIVE_BACKGROUND // you will see what I am looking for, despite nasty check box Button button = new Button(shell, SWT.PUSH); button.setImage(new Image(display, "moneyfast.gif")); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

  • Merge DataGrid ColumnHeaders

    - by Vishal
    I would like to merge two column-Headers. Before you go and mark this question as duplicate please read further. I don't want a super-Header. I just want to merge two column-headers. Take a look at image below: Can you see two columns with headers Mobile Number 1 and Mobile Number 2? I want to show there only 1 column header as Mobile Numbers. Here is the XAML used for creating above mentioned dataGrid: <DataGrid Grid.Row="1" Margin="0,10,0,0" ItemsSource="{Binding Ledgers}" IsReadOnly="True" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTextColumn Header="Customer Name" Binding="{Binding LedgerName}" /> <DataGridTextColumn Header="City" Binding="{Binding City}" /> <DataGridTextColumn Header="Mobile Number 1" Binding="{Binding MobileNo1}" /> <DataGridTextColumn Header="Mobile Number 2" Binding="{Binding MobileNo2}" /> <DataGridTextColumn Header="Opening Balance" Binding="{Binding OpeningBalance}" /> </DataGrid.Columns> </DataGrid> Update1: Update2 I have created a converter as follows: public class MobileNumberFormatConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value != null && value != DependencyProperty.UnsetValue) { if (value.ToString().Length <= 15) { int spacesToAdd = 15 - value.ToString().Length; string s = value.ToString().PadRight(value.ToString().Length + spacesToAdd); return s; } return value.ToString().Substring(0, value.ToString().Length - 3) + "..."; } return ""; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } I have used it in XAML as follows: <DataGridTextColumn Header="Mobile Numbers"> <DataGridTextColumn.Binding> <MultiBinding StringFormat=" {0} {1}"> <Binding Path="MobileNo1" Converter="{StaticResource mobileNumberFormatConverter}"/> <Binding Path="MobileNo2" Converter="{StaticResource mobileNumberFormatConverter}"/> </MultiBinding> </DataGridTextColumn.Binding> </DataGridTextColumn> The output I got: Update3: At last I got the desired output. Here is the code for Converter: public class MobileNumberFormatConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value != null && value != DependencyProperty.UnsetValue) { if (parameter.ToString().ToUpper() == "N") { if (value.ToString().Length <= 15) { return value.ToString(); } else { return value.ToString().Substring(0, 12); } } else if (parameter.ToString().ToUpper() == "S") { if (value.ToString().Length <= 15) { int spacesToAdd = 15 - value.ToString().Length; string spaces = ""; return spaces.PadRight(spacesToAdd); } else { return "..."; } } } return ""; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } Here is my XAML: <DataGridTemplateColumn Header="Mobile Numbers"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock> <Run Text="{Binding MobileNo1, Converter={StaticResource mobileNumberFormatConverter}, ConverterParameter=N}" /> <Run Text="{Binding MobileNo1, Converter={StaticResource mobileNumberFormatConverter}, ConverterParameter=S}" FontFamily="Consolas"/> <Run Text=" " FontFamily="Consolas"/> <Run Text="{Binding MobileNo2, Converter={StaticResource mobileNumberFormatConverter}, ConverterParameter=N}" /> <Run Text="{Binding MobileNo2, Converter={StaticResource mobileNumberFormatConverter}, ConverterParameter=S}" FontFamily="Consolas"/> </TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> Output:

  • Why doesn't the default model binder update my partial view model on postback?

    - by bdnewbe
    I have a class that contains another class as one of its properties. public class SiteProperties { public SiteProperties() { DropFontFamily = "Arial, Helvetica, Sans-serif"; } public string DropFontFamily { get; set; } private ResultPageProperties m_ResultPagePropertyList; public ResultPageProperties ResultPagePropertyList { get { if (m_ResultPagePropertyList == null) m_ResultPagePropertyList = new ResultPageProperties(); return m_ResultPagePropertyList; } set { m_ResultPagePropertyList = value; } } } The second class has just one property public class ResultPageProperties { public ResultPageProperties() { ResultFontFamily = "Arial, Helvetica, Sans-serif"; } public string ResultFontFamily { get; set; } } My controller just grabs the SiteProperties and returns the view. On submit, it accepts SiteProperties and returns the same view. public class CompanyController : Controller { public ActionResult SiteOptions(int id) { SiteProperties site = new SiteProperties(); PopulateProperyDropDownLists(); return View("SiteOptions", site); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult SiteOptions(SiteProperties properties) { PopulateProperyDropDownLists(); return View("SiteOptions", properties); } private void PopulateProperyDropDownLists() { var fontFamilyList = new List<SelectListItem>(); fontFamilyList.Add(new SelectListItem() { Text = "Arial, Helvetica, Sans-serif", Value = "Arial, Helvetica, Sans-serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Times New Roman, Times, serif", Value = "Times New Roman, Times, serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Courier New, Courier, Monospace", Value = "Courier New, Courier, Monospace" }); ViewData["FontFamilyList"] = fontFamilyList; } } The view contains a partial view that renders the ResultPageProperties Model. <% using (Html.BeginForm("SiteOptions", "Company", FormMethod.Post)) {%> <p><input type="submit" value="Submit" /></p> <div>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.DropFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesDropDownExample" })%> </div> <% Html.RenderPartial("ResultPagePropertyInput", Model.ResultPagePropertyList); %> <% } %> The partial is just <div style='margin-top: 1em;'>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.ResultFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesResultPageExample" })%> </div> OK, so when the page renders, you get "Arial, ..." in both selects. If you choose another option for both and click submit, the binder populates the SiteProperties object and passes it to the controller. However, the ResultFontFamily always contains the original value. I was expecting it to have the value the user selected. What am I missing?

  • Rogue PropertyChanged notifications from ViewModel

    - by user1886323
    The following simple program is causing me a Databinding headache. I'm new to this which is why I suspect it has a simple answer. Basically, I have two text boxes bound to the same property myString. I have not set up the ViewModel (simply a class with one property, myString) to provide any notifications to the View for when myString is changed, so even although both text boxes operate a two way binding there should be no way that the text boxes update when myString is changed, am I right? Except... In most circumstances this is true - I use the 'change value' button at the bottom of the window to change the value of myString to whatever the user types into the adjacent text box, and the two text boxes at the top, even although they are bound to myString, do not change. Fine. However, if I edit the text in TextBox1, thus changing the value of myString (although only when the text box loses focus due to the default UpdateSourceTrigger property, see reference), TextBox2 should NOT update as it shouldn't receive any updates that myString has changed. However, as soon as TextBox1 loses focus (say click inside TextBox2) TextBox2 is updated with the new value of myString. My best guess so far is that because the TextBoxes are bound to the same property, something to do with TextBox1 updating myString gives TextBox2 a notification that it has changed. Very confusing as I haven't used INotifyPropertyChanged or anything like that. To clarify, I am not asking how to fix this. I know I could just change the binding mode to a oneway option. I am wondering if anyone can come up with an explanation for this strange behaviour? ViewModel: namespace WpfApplication1 { class ViewModel { public ViewModel() { _myString = "initial message"; } private string _myString; public string myString { get { return _myString; } set { if (_myString != value) { _myString = value; } } } } } View: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="MainWindow" Height="350" Width="525"> <Window.DataContext> <local:ViewModel /> </Window.DataContext> <Grid> <!-- The culprit text boxes --> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,70,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,120,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}"/> <!--The buttons allowing manual change of myString--> <Button Name="changevaluebutton" Content="change value" Click="ButtonUpdateArtist_Click" Margin="12,245,416,43" Width="75" /> <Button Content="Show value" Height="23" HorizontalAlignment="Left" Margin="12,216,0,0" Name="showvaluebutton" VerticalAlignment="Top" Width="75" Click="showvaluebutton_Click" /> <Label Content="" Height="23" HorizontalAlignment="Left" Margin="116,216,0,0" Name="showvaluebox" VerticalAlignment="Top" Width="128" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="116,245,0,0" Name="changevaluebox" VerticalAlignment="Top" Width="128" /> <!--simply some text--> <Label Content="TexBox1" Height="23" HorizontalAlignment="Left" Margin="99,70,0,0" Name="label1" VerticalAlignment="Top" Width="61" /> <Label Content="TexBox2" Height="23" HorizontalAlignment="Left" Margin="99,118,0,0" Name="label2" VerticalAlignment="Top" Width="61" /> </Grid> </Window> Code behind for view: namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { ViewModel viewModel; public MainWindow() { InitializeComponent(); viewModel = (ViewModel)this.DataContext; } private void showvaluebutton_Click(object sender, RoutedEventArgs e) { showvaluebox.Content = viewModel.myString; } private void ButtonUpdateArtist_Click(object sender, RoutedEventArgs e) { viewModel.myString = changevaluebox.Text; } } }

  • Getting code-first Entity Framework to build tables on SQL Azure

    - by NER1808
    I am new the code-first Entity Framework. I have tried a few things now, but can't get EF to construct any tables in the my SQL Azure database. Can anyone advise of some steps and settings I should check. The membership provider has no problems create it's tables. I have added the PersistSecurityInfo=True in the connection string.

  • Window's content disappears when minimized

    - by Carmen Cojocaru
    I have a simple class that draws a line when mouse dragging or a dot when mouse pressing(releasing). When I minimize the application and then restore it, the content of the window disappears except the last dot (pixel). I understand that the method super.paint(g) repaints the background every time the window changes, but the result seems to be the same whether I use it or not. The difference between the two of them is that when I don't use it there's more than a pixel painted on the window, but not all my painting. How can I fix this? Here is the class. package painting; import java.awt.*; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionAdapter; import javax.swing.JFrame; import javax.swing.JPanel; class CustomCanvas extends Canvas{ Point oldLocation= new Point(10, 10); Point location= new Point(10, 10); Dimension dimension = new Dimension(2, 2); CustomCanvas(Dimension dimension){ this.dimension = dimension; this.init(); addListeners(); } private void init(){ oldLocation= new Point(0, 0); location= new Point(0, 0); } public void paintLine(){ if ((location.x!=oldLocation.x) || (location.y!=oldLocation.y)) { repaint(location.x,location.y,1,1); } } private void addListeners(){ addMouseListener(new MouseAdapter(){ @Override public void mousePressed(MouseEvent me){ oldLocation = location; location = new Point(me.getX(), me.getY()); paintLine(); } @Override public void mouseReleased(MouseEvent me){ oldLocation = location; location = new Point(me.getX(), me.getY()); paintLine(); } }); addMouseMotionListener(new MouseMotionAdapter() { @Override public void mouseDragged(MouseEvent me){ oldLocation = location; location = new Point(me.getX(), me.getY()); paintLine(); } }); } @Override public void paint(Graphics g){ super.paint(g); g.setColor(Color.red); g.drawLine(location.x, location.y, oldLocation.x, oldLocation.y); } @Override public Dimension getMinimumSize() { return dimension; } @Override public Dimension getPreferredSize() { return dimension; } } class CustomFrame extends JPanel { JPanel displayPanel = new JPanel(new BorderLayout()); CustomCanvas canvas = new CustomCanvas(new Dimension(200, 200)); public CustomFrame(String titlu) { canvas.setBackground(Color.white); displayPanel.add(canvas, BorderLayout.CENTER); this.add(displayPanel); } } public class CustomCanvasFrame { public static void main(String args[]) { CustomFrame panel = new CustomFrame("Test Paint"); JFrame f = new JFrame(); f.add(panel); f.pack(); SwingConsole.run(f, 700, 700); } }

  • Code only runs properly if debugging step-by-step

    - by Cornwell
    Hello, I'm making a webserver and I've come up with some very strange problems. My server was running as expected yesterday when I turned off my laptop, but today it only sends the http headers (I didn't change anything) When a user requests a file, if I send them using the following code, it works perfectly: while ((n = fread(data, 1, sizeof(data), file)) > 0) send(ts, data, n, 0); but if I change it to this, it only sends ~2% of the file. And that's not a random number, it actually only sends about 2% of the file. while ((n = fread(data, 1, sizeof(data), file)) > 0) web.Send(data); int WEB::Send(string data) { return send(TempSocket, data.c_str(), data.size(), 0); } changing string to char* doesn't solve the problem. I'm using visual studio2010. If I run my code step-by-step, I am able to solve problem #1, everything gets sent. And that is my main problem. I do not understand why it happens. Hopefully someone can explain it to me. Thanks in advance. EDIT: int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE hPrev, LPSTR lpCmd,int nShow) { SOCKET MainSocket=0; MSG msg; RedirectIOToConsole(); CreateThread(NULL, NULL, ListenThread, NULL, NULL, NULL); while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } WSACleanup(); closesocket(MainSocket); MainSocket = INVALID_SOCKET; return msg.wParam; } DWORD WINAPI ListenThread(LPVOID lparam) { SOCKET MainSocket; WSADATA wsaData; SOCKET tmpsock; struct sockaddr_in local, from; int fromlen=sizeof(from); WSAStartup(MAKEWORD(2, 2), &wsaData); local.sin_family=AF_INET; local.sin_addr.s_addr=INADDR_ANY; local.sin_port=htons(PORT); MainSocket=socket(AF_INET,SOCK_STREAM,0); if(MainSocket==INVALID_SOCKET) { return 0; } if(bind(MainSocket,(struct sockaddr*)&local,sizeof(local))!=0) { return 0; } if(listen(MainSocket,10)!=0) { return 0; } while(1) { tmpsock = accept(MainSocket,(struct sockaddr*)&from,&fromlen); CreateThread(NULL, NULL, SlaveThread, (LPVOID)tmpsock, NULL, NULL); } } DWORD WINAPI SlaveThread(LPVOID lparam) { SOCKET ts = (SOCKET)lparam;//temporary socket ...... char data[4096]; int n; unsigned long int length = statbuf.st_size; web.SendHeaders(200, "OK", format("Content-Disposition: attachment; filename=\"%s\"", FileName.c_str()).c_str(), web.GetMimeType(ReqPath.c_str()), length, statbuf.st_mtime); unsigned long int i=0,d=0; while ((n = fread(data, 1, sizeof(data), file)) > 0) { d+=send(ts, data, n, 0); i+=n; } printf("%i=%i=%i\n", length,i,d); fclose(file);

  • CFStrings and storing them into models, related topics

    - by Jasconius
    I have a very frustrating issue that I believe involves CFStringRef and passing them along to custom model properties. The code is pretty messy right now as I am in a debug state, but I will try to describe the problem in words as best as I can. I have a custom model, User, which for irrelevant reasons, I am storing CF types derived from the Address Book API into. Examples include: Name, email as NSStrings. I am simply retrieving the CFStringRef value from the AddressBook API and casting as a string, whereupon I assign to the custom model instance and then CFRelease the string. These NSString properties are set as (nonatomic, retain). I then store this model into an NSArray, and I use this Array as a datasource for a UITableView When accessing the object in the cellForRowAtIndexPath, I get a memory access error. When I do a Debug, I see that the value for this datasource array appears at first glance to be corrupted. I've seen strange values assigned to it, including just plain strings, such as one that I fed to an NSLog function in earlier in the method. So, the thing that leads me to believe that this is Core Foundation related is that I am executing this exact same code, in the same class even, on non-Address Book data, in fact, just good old JSON parsed strings, which produce true Cocoa NSStrings, that I follow the same exact steps to create the datasource array. This code works fine. I have a feeling that my (retain) property declaration and/or my [stringVar release] in my custom model dealloc method may be causing memory problems (since it is my understanding that you shouldn't call a Cocoa retain or release on a CF object). Here is the code. I know some of this is super-roundabout but I was trying to make things as explicit as possible for the sake of debugging. NSMutableArray *friendUsers = [[NSMutableArray alloc] init]; int numberOfPeople = CFArrayGetCount(people); for (int i = 0; i < numberOfPeople; i++) { ABMutableMultiValueRef emails = ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonEmailProperty); if (ABMultiValueGetCount(emails) > 0) { User *addressContact = [[User alloc] init]; NSString *firstName = (NSString *)ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonFirstNameProperty); NSString *lastName = (NSString *)ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonLastNameProperty); NSLog(@"%@ and %@", firstName, lastName); NSString *fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName]; NSString *email = [NSString stringWithFormat:@"%@", (NSString *)ABMultiValueCopyValueAtIndex(emails, 0)]; NSLog(@"the email: %@", email); [addressContact setName:fullName]; [addressContact setEmail:email]; [friendUsers addObject:addressContact]; [firstName release]; [lastName release]; [email release]; [addressContact release]; } CFRelease(emails); } NSLog(@"friend count: %d", [friendUsers count]); abFriends = [NSArray arrayWithArray:friendUsers]; [friendUsers release]; All of that works, every logging statement returns as expected. But when I use abFriends as a datasource, poof. Dead. Is my approach all wrong? Any advice?

    Hi, I'm kind of a beginner when it comes to java programming, and I have a project in school where I'm going to create a game much like Icy Tower.

  • NHibernate child deletion problem.

    - by JMSA
    Suppose, I have saved some permissions in the database by using this code: RoleRepository roleRep = new RoleRepository(); Role role = new Role(); role.PermissionItems = Permission.GetList(); roleRep .SaveOrUpdate(role); Now, I need this code to delete the PermissionItem(s) associated with a Role when role.PermissionItems == null. Here is the code: RoleRepository roleRep = new RoleRepository(); Role role = roleRep.Get(roleId); role.PermissionItems = null; roleRep .SaveOrUpdate(role); But this is not happening. What should be the correct way to cope with this situation? What/how should I change, hbm-file or persistance code? Role.cs public class Role { public virtual string RoleName { get; set; } public virtual bool IsActive { get; set; } public virtual IList<Permission> PermissionItems { get; set; } } Role.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="POCO" namespace="POCO"> <class name="Role" table="Role"> <id name="ID" column="ID"> <generator class="native" /> </id> <property name="RoleName" column="RoleName" /> <property name="IsActive" column="IsActive" type="System.Boolean" /> <bag name="PermissionItems" table="Permission" cascade="all" inverse="true"> <key column="RoleID"/> <one-to-many class="Permission" /> </bag> </class> </hibernate-mapping> Permission.cs public class Permission { public virtual string MenuItemKey { get; set; } public virtual int RoleID { get; set; } public virtual Role Role { get; set; } } Permission.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="POCO" namespace="POCO"> <class name="Permission" table="Permission"> <id name="ID" column="ID"> <generator class="native"/> </id> <property name="MenuItemKey" column="MenuItemKey" /> <property name="RoleID" column="RoleID" /> <many-to-one name="Role" column="RoleID" not-null="true" cascade="all"> </many-to-one> </class> </hibernate-mapping>

  • How to select chosen columns from two different entities into one DTO using NHibernate?

    - by Pawel Krakowiak
    I have two classes (just recreating the problem): public class User { public virtual int Id { get; set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual IList<OrgUnitMembership> OrgUnitMemberships { get; set; } } public class OrgUnitMembership { public virtual int UserId { get; set; } public virtual int OrgUnitId { get; set; } public virtual DateTime JoinDate { get; set; } public virtual DateTime LeaveDate { get; set; } } There's a Fluent NHibernate map for both, of course: public class UserMapping : ClassMap<User> { public UserMapping() { Table("Users"); Id(e => e.Id).GeneratedBy.Identity(); Map(e => e.FirstName); Map(e => e.LastName); HasMany(x => x.OrgUnitMemberships) .KeyColumn(TypeReflector<OrgUnitMembership> .GetPropertyName(p => p.UserId))).ReadOnly().Inverse(); } } public class OrgUnitMembershipMapping : ClassMap<OrgUnitMembership> { public OrgUnitMembershipMapping() { Table("OrgUnitMembership"); CompositeId() .KeyProperty(x=>x.UserId) .KeyProperty(x=>x.OrgUnitId); Map(x => x.JoinDate); Map(x => x.LeaveDate); References(oum => oum.OrgUnit) .Column(TypeReflector<OrgUnitMembership> .GetPropertyName(oum => oum.OrgUnitId)).ReadOnly(); References(oum => oum.User) .Column(TypeReflector<OrgUnitMembership> .GetPropertyName(oum => oum.UserId)).ReadOnly(); } } What I want to do is to retrieve some users based on criteria, but I would like to combine all columns from the Users table with some columns from the OrgUnitMemberships table, analogous to a SQL query: select u.*, m.JoinDate, m.LeaveDate from Users u inner join OrgUnitMemberships m on u.Id = m.UserId where m.OrgUnitId = :ouid I am totally lost, I tried many different options. Using a plain SQL query almost works, but because there are some nullable enums in the User class AliasToBean fails to transform, otherwise wrapping a SQL query would work like this: return Session .CreateSQLQuery(sql) .SetParameter("ouid", orgUnitId) .SetResultTransformer(Transformers.AliasToBean<UserDTO>()) .List<UserDTO>() I tried the code below as a test (a few different variants), but I'm not sure what I'm doing. It works partially, I get instances of UserDTO back, the properties coming from OrgUnitMembership (dates) are filled, but all properties from User are null: User user = null; OrgUnitMembership membership = null; UserDTO dto = null; var users = Session.QueryOver(() => user) .SelectList(list => list .Select(() => user.Id) .Select(() => user.FirstName) .Select(() => user.LastName)) .JoinAlias(u => u.OrgUnitMemberships, () => membership) //.JoinQueryOver<OrgUnitMembership>(u => u.OrgUnitMemberships) .SelectList(list => list .Select(() => membership.JoinDate).WithAlias(() => dto.JoinDate) .Select(() => membership.LeaveDate).WithAlias(() => dto.LeaveDate)) .TransformUsing(Transformers.AliasToBean<UserDTO>()) .List<UserDTO>();

  • Why is FubuMVC new()ing up my view model in PartialForEach?

    - by Jon M
    I'm getting started with FubuMVC and I have a simple Customer - Order relationship I'm trying to display using nested partials. My domain objects are as follows: public class Customer { private readonly IList<Order> orders = new List<Order>(); public string Name { get; set; } public IEnumerable<Order> Orders { get { return orders; } } public void AddOrder(Order order) { orders.Add(order); } } public class Order { public string Reference { get; set; } } I have the following controller classes: public class CustomersController { public IndexViewModel Index(IndexInputModel inputModel) { var customer1 = new Customer { Name = "John Smith" }; customer1.AddOrder(new Order { Reference = "ABC123" }); return new IndexViewModel { Customers = new[] { customer1 } }; } } public class IndexInputModel { } public class IndexViewModel { public IEnumerable<Customer> Customers { get; set; } } public class IndexView : FubuPage<IndexViewModel> { } public class CustomerPartial : FubuControl<Customer> { } public class OrderPartial : FubuControl<Order> { } IndexView.aspx: (standard html stuff trimmed) <div> <%= this.PartialForEach(x => x.Customers).Using<CustomerPartial>() %> </div> CustomerPartial.ascx: <%@ Control Language="C#" Inherits="FubuDemo.Controllers.Customers.CustomerPartial" %> <div> Customer Name: <%= this.DisplayFor(x => x.Name) %> <br /> Orders: (<%= Model.Orders.Count() %>) <br /> <%= this.PartialForEach(x => x.Orders) %> </div> OrderPartial.ascx: <%@ Control Language="C#" Inherits="FubuDemo.Controllers.Customers.OrderPartial" %> <div> Order <br /> Ref: <%= this.DisplayFor(x => x.Reference) %> </div> When I view Customers/Index, I see the following: Customers Customer Name: John Smith Orders: (1) It seems that in CustomerPartial.ascx, doing Model.Orders.Count() correctly picks up that 1 order exists. However PartialForEach(x = x.Orders) does not, as nothing is rendered for the order. If I set a breakpoint on the Order constructor, I see that it initially gets called by the Index method on CustomersController, but then it gets called by FubuMVC.Core.Models.StandardModelBinder.Bind, so it is getting re-instantiated by FubuMVC and losing the content of the Orders collection. This isn't quite what I'd expect, I would think that PartialForEach would just pass the domain object directly into the partial. Am I missing the point somewhere? What is the 'correct' way to achieve this kind of result in Fubu?

  • Accessing Layout Items from inside Widget AppWidgetProvider

    - by cam4mav
    I am starting to go insane trying to figure this out. It seems like it should be very easy, I'm starting to wonder if it's possible. What I am trying to do is create a home screen widget, that only contains an ImageButton. When it is pressed, the idea is to change some setting (like the wi-fi toggle) and then change the Buttons image. I have the ImageButton declared like this in my main.xml <ImageButton android:id="@+id/buttonOne" android:src="@drawable/button_normal_ringer" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> my AppWidgetProvider class, named ButtonWidget * note that the RemoteViews class is a locally stored variable. this allowed me to get access to the RViews layout elements... or so I thought. @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { remoteViews = new RemoteViews(context.getPackageName(), R.layout.main); Intent active = new Intent(context, ButtonWidget.class); active.setAction(VIBRATE_UPDATE); active.putExtra("msg","TESTING"); PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0); remoteViews.setOnClickPendingIntent(R.id.buttonOne, actionPendingIntent); appWidgetManager.updateAppWidget(appWidgetIds, remoteViews); } @Override public void onReceive(Context context, Intent intent) { // v1.5 fix that doesn't call onDelete Action final String action = intent.getAction(); Log.d("onReceive",action); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { // check, if our Action was called if (intent.getAction().equals(VIBRATE_UPDATE)) { String msg = "null"; try { msg = intent.getStringExtra("msg"); } catch (NullPointerException e) { Log.e("Error", "msg = null"); } Log.d("onReceive",msg); if(remoteViews != null){ Log.d("onReceive",""+remoteViews.getLayoutId()); remoteViews.setImageViewResource(R.id.buttonOne, R.drawable.button_pressed_ringer); Log.d("onReceive", "tried to switch"); } else{ Log.d("F!", "--naughty language used here!!!--"); } } super.onReceive(context, intent); } } so, I've been testing this and the onReceive method works great, I'm able to send notifications and all sorts of stuff (removed from code for ease of reading) the one thing I can't do is change any properties of the view elements. To try and fix this, I made RemoteViews a local and static private variable. Using log's I was able to see that When multiple instances of the app are on screen, they all refer to the one instance of RemoteViews. perfect for what I'm trying to do The trouble is in trying to change the image of the ImageButton. I can do this from within the onUpdate method using this. remoteViews.setImageViewResource(R.id.buttonOne, R.drawable.button_pressed_ringer); that doesn't do me any good though once the widget is created. For some reason, even though its inside the same class, being inside the onReceive method makes that line not work. That line used to throw a Null pointer as a matter of fact, until I changed the variable to static. now it passes the null test, refers to the same layoutId as it did at the start, reads the line, but it does nothing. Its like the code isn't even there, just keeps chugging along. SO...... Is there any way to modify layout elements from within a widget after the widget has been created!? I want to do this based on the environment, not with a configuration activity launch. I've been looking at various questions and this seems to be an issue that really hasn't been solved, such as link text and link text oh and for anyone who finds this and wants a good starting tutorial for widgets, this is easy to follow (though a bit old, it gets you comfortable with widgets) .pdf link text hopefully someone can help here. I kinda have the feeling that this is illegal and there is a different way to go about this. I would LOVE to be told another approach!!!! Thanks

  • Application stops on back button in new activity

    - by Bruno Almeida
    I have this application, that have a listView, and when I click in a item on listView, it opens a new activity. That works fine! But, if I open the new activity and than press the "back button" the application "Unfortunately, has stopped". Is there something I'm doing wrong? Here is my code: First activity: public class AndroidSQLite extends Activity { private SQLiteAdapter mySQLiteAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ListView listContent = (ListView)findViewById(R.id.contentlist); mySQLiteAdapter = new SQLiteAdapter(this); mySQLiteAdapter.openToRead(); Cursor cursor = mySQLiteAdapter.queueAll(); startManagingCursor(cursor); String[] from = new String[]{SQLiteAdapter.KEY_NOME,SQLiteAdapter.KEY_ID}; int[] to = new int[]{R.id.text,R.id.id}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.row, cursor, from, to); listContent.setAdapter(cursorAdapter); listContent.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(getBaseContext(), id + "", Toast.LENGTH_LONG).show(); Intent details = new Intent(getApplicationContext(),DetailsPassword.class); startActivity(details); } }); mySQLiteAdapter.close(); } } Second Activity: public class DetailsPassword extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView text = new TextView(getApplicationContext()); text.setText("Text to show"); setContentView(text); } } // ===== EDITED ===== here is the Stack Track 10-30 08:55:05.744: E/AndroidRuntime(28046): FATAL EXCEPTION: main 10-30 08:55:05.744: E/AndroidRuntime(28046): java.lang.RuntimeException: Unable to resume activity {com.example.sqliteexemple2/com.example.sqliteexemple2.AndroidSQLite}: java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor@4180a370 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2701) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2729) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1250) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.os.Handler.dispatchMessage(Handler.java:99) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.os.Looper.loop(Looper.java:137) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.main(ActivityThread.java:4931) 10-30 08:55:05.744: E/AndroidRuntime(28046): at java.lang.reflect.Method.invokeNative(Native Method) 10-30 08:55:05.744: E/AndroidRuntime(28046): at java.lang.reflect.Method.invoke(Method.java:511) 10-30 08:55:05.744: E/AndroidRuntime(28046): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 10-30 08:55:05.744: E/AndroidRuntime(28046): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:558) 10-30 08:55:05.744: E/AndroidRuntime(28046): at dalvik.system.NativeStart.main(Native Method) 10-30 08:55:05.744: E/AndroidRuntime(28046): Caused by: java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor@4180a370 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.Activity.performRestart(Activity.java:5051) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.Activity.performResume(Activity.java:5074) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2691) 10-30 08:55:05.744: E/AndroidRuntime(28046): ... 10 more

  • setting something disposed or invisible java

    - by OVERTONE
    this might be simple enough as just inserting the right method but i cant seem to get it right. i have a simple program with two buttons. each one changes the picture above them. but anytime i click the buttons i get some odd awt event queue error. i think its because im trying to add something to a frame after its already been made. package icnon; import javax.imageio.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class FrameIconExample extends JFrame implements ActionListener { JLabel j; JPanel p, l, k; JButton picOne, picTwo; Container cPane; public FrameIconExample() { JButton picOne = new JButton("picOne"); JButton picTwo = new JButton("picTwo"); picOne.setName("picOne"); picTwo.setName("picTwo"); picOne.addActionListener(this); picTwo.addActionListener(this); JPanel p = new JPanel(new GridLayout(2, 1)); JPanel l = new JPanel(new FlowLayout()); JPanel k = new JPanel(new FlowLayout()); cPane = getContentPane(); j = new JLabel(new ImageIcon("../meet/src/images/beautiful-closeup-portrait-photography.jpg")); l.add(j); k.add(picOne); k.add(picTwo); p.add(l); p.add(k); add(p); } public static void main(String[] args) { FrameIconExample frame = new FrameIconExample(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(new Dimension(300, 800)); frame.setTitle("Frame Icon Example"); // Display the form frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { JButton temp = (JButton) e.getSource(); String src = "../meet/src/images/Majken Kruse portrait - john.jpg"; //System.out.println(src + " " + temp.getName()); if(temp.getName().equalsIgnoreCase("picOne")) { src = "../meet/src/images/beautiful-closeup-portrait-photography.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("1"); } if(temp.getName().equalsIgnoreCase("picTwo")) { src = "../icontest/images/Majken Kruse portrait - john.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("2"); } } } its all just the one program so if you copy paste it into an editor you can see the stack trace. but the source of the image files wont be there. does anyone know how id do it? or where im goin wrong? stack trace: ../meet/src/images/beautiful-closeup-portrait-photography.jpg picOne Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at icnon.FrameIconExample.actionPerformed(FrameIconExample.java:68) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

  • Program is not displaying output correctly

    - by Dave Lee
    My program is suppose to display information from a text file. The text file is here http://pastebin.com/qB6nX2x4 I cant find the problem in my program.

  • How to find an element in an array in C

    - by gkaykck
    I am trying to find the location of an element in the array. I have tried to use this code i generated for(i=0;i<10;i++) { if (strcmp(temp[0],varptr[i])==0) j=i; } varptr is a pointer which points to array var[11][10] and it is by the definition *varptr[11][10]. I have assigned strings to var[i] and i want to get the "i" number of my element NOT THE ADRESS. Thanks for any comment. EDit: temp is also a pointer which points to the string that i want to check. Also i am using the 2D array for keeping variable names and their address. So yes i want to keep it inside a 2D array. The question is this code is not working at all, it does not assigns i to j, so i wonder where is the problem with this idea? writing a "break" does not change if the code works or not, it just optimizes the code a little. Full Code: #include <stdio.h> #include <string.h> #include <ctype.h> double atof(char*); int main(void) { char in[100], *temp[10],var[11][10],*varptr[11][10]; int i,j, n = 0,fullval=0; double val[11]; strcpy(var[11], "ans"); for(i=0;i<11;i++) { for(j=0;j<10;j++) varptr[i][j]=&var[i][j]; } START: printf("Enter the expression: "); fflush(stdout); for(i=0;i<10;i++) temp[i]=NULL; if (fgets(in, sizeof in, stdin) != NULL) { temp[0] = strtok(in, " "); if (temp[0] != NULL) { for (n = 1; n < 10 && (temp[n] = strtok(NULL," ")) != NULL; n++) ; } if (*temp[0]=="quit") { goto FINISH;} if (isdigit(*temp[0])) { if (*temp[1]=='+') val[0] = atof(temp[0])+atof(temp[2]); else if (*temp[1]=='-') val[0] = atof(temp[0])-atof(temp[2]); else if (*temp[1]=='*') val[0] = atof(temp[0])*atof(temp[2]); else if (*temp[1]=='/') val[0] = atof(temp[0])/atof(temp[2]); printf("%s = %f\n",var[11],val[0]); goto START; } else if (temp[1]==NULL) //asking the value of a variable { for(i=0;i<10;i++) { if (strcmp(temp[0],varptr[i])==0) j=i; } printf("%s = %d\n",var[j],val[j]); goto START; } if (*temp[1]==61) { strcpy(var[fullval], temp[0]); if ((temp[3])!=NULL) { } val[fullval]=atof(temp[2]); printf("%s = %f\n",var[fullval],val[fullval]); fullval++; goto START; } if (*temp[1]!=61) { } } getch(); FINISH: return 0; }

  • MVC multi page form losing session

    - by Bryan
    I have a multi-page form that's used to collect leads. There are multiple versions of the same form that we call campaigns. Some campaigns are 3 page forms, others are 2 pages, some are 1 page. They all share the same lead model and campaign controller, etc. There is 1 action for controlling the flow of the campaigns, and a separate action for submitting all the lead information into the database. I cannot reproduce this locally, and there are checks in place to ensure users can't skip pages. Session mode is InProc. This runs after every POST action which stores the values in session: protected override void OnActionExecuted(ActionExecutedContext filterContext) { base.OnActionExecuted(filterContext); if (this.Request.RequestType == System.Net.WebRequestMethods.Http.Post && this._Lead != null) ParentStore.Lead = this._Lead; } This is the Lead property within the controller: private Lead _Lead; /// <summary> /// Gets the session stored Lead model. /// </summary> /// <value>The Lead model stored in session.</value> protected Lead Lead { get { if (this._Lead == null) this._Lead = ParentStore.Lead; return this._Lead; } } ParentStore class: public static class ParentStore { internal static Lead Lead { get { return SessionStore.Get<Lead>(Constants.Session.Lead, new Lead()); } set { SessionStore.Set(Constants.Session.Lead, value); } } Campaign POST action: [HttpPost] public virtual ActionResult Campaign(Lead lead, string campaign, int page) { if (this.Session.IsNewSession) return RedirectToAction("Campaign", new { campaign = campaign, page = 0 }); if (ModelState.IsValid == false) return View(GetCampaignView(campaign, page), this.Lead); TrackLead(this.Lead, campaign, page, LeadType.Shared); return RedirectToAction("Campaign", new { campaign = campaign, page = ++page }); } The problem is occuring between the above action, and before the following Submit action executes: [HttpPost] public virtual ActionResult Submit(Lead lead, string campaign, int page) { if (this.Session.IsNewSession || this.Lead.Submitted || !this.LeadExists) return RedirectToAction("Campaign", new { campaign = campaign, page = 0 }); lead.AddCustomQuestions(); MergeLead(campaign, lead, this.AdditionalQuestionsType, false); if (ModelState.IsValid == false) return View(GetCampaignView(campaign, page), this.Lead); var sharedLead = this.Lead.ToSharedLead(Request.Form.ToQueryString(false)); //Error occurs here and sends me an email with whatever values are in the form collection. EAUtility.ProcessLeadProxy.SubmitSharedLead(sharedLead); this.Lead.Submitted = true; VisitorTracker.DisplayConfirmationPixel = true; TrackLead(this.Lead, campaign, page, LeadType.Shared); return RedirectToAction(this.ConfirmationView); } Every visitor to our site gets a unique GUID visitorID. But when these error occurs there is a different visitorID between the Campaign POST and the Submit POST. Because we track each form submission via the TrackLead() method during campaign and submit actions I can see session is being lost between calls, despite the OnActionExecuted firing after every POST and storing the form in session. So when there are errors, we get half the form under one visitorID and the remainder of the form under a different visitorID. Luckily we use a third party service which sends an API call every time a form value changes which uses it's own ID. These IDs are consistent between the first half of the form, and the remainder of the form, and the only way I can save the leads from the lost session issues. I should also note that this works fine 99% of the time. EDIT: I've modified my code to explicitly store my lead object in TempData and used the TempData.Keep() method to persist the object between subsequent requests. I've only deployed this behavior to 1 of my 3 sites but so far so good. I had also tried storing my lead objects in Session directly in the controller action i.e., Session.Add("lead", this._Lead); which uses HTTPSessionStateBase, attempting to circumvent the wrapper class, instead of HttpContext.Current.Session which uses HTTPSessionState. This modification made no difference on the issue, as expected.
