• Run unit tests in Jenkins / Hudson in automated fashion from dev to build server

  - by Kevin Donde

  We are currently running a Jenkins (Hudson) CI server to build and package our .net web projects and database projects. Everything is working great but I want to start writing unit tests and then only passing the build if the unit tests pass. We are using the built in msbuild task to build the web project. With the following arguments ... MsBuild Version .NET 4.0 MsBuild Build File ./WebProjectFolder/WebProject.csproj Command Line Arguments ./target:Rebuild /p:Configuration=Release;DeployOnBuild=True;PackageLocation=".\obj\Release\WebProject.zip";PackageAsSingleFile=True We need to run automated tests over our code that run automatically when we build on our machines (post build event possibly) but also run when Jenkins does a build for that project. If you run it like this it doesn't build the unit tests project because the web project doesn't reference the test project. The test project would reference the web project but I'm pretty sure that would be butchering our automated builds as they exist primarily to build and package our deployments. Running these tests should be a step in that automated build and package process. Options ... Create two Jenkins jobs. one to run the tests ... if the tests pass another build is triggered which builds and packages the web project. Put the post build event on the test project. Build the solution instead of the project (make sure the solution contains the required tests) and put post build events on any test projects that would run the nunit console to run the tests. Then use the command line to copy all the required files from each of the bin and content directories into a package. Just build the test project in jenkins instead of the web project in jenkins. The test project would reference the web project (depending on what you're testing) and build it. Problems ... There's two jobs and not one. Two things to debug not one. One to see if the tests passed and one to build and compile the web project. The tests could pass but the build could fail if its something that isn't used by what you're testing ... This requires us to know exactly what goes into the build. Right now msbuild does it all for us. If you have multiple teams working on a project everytime an extra folder is created you have to worry about the possibly brittle command line statements. This seems like a corruption of our main purpose here. The tests should be a step in this process not the overriding most important thing in this process. I'm also not 100% sure that a triggered build is the same as a normal build does it do all the same things as a normal build. Move all the correct files in the same way move them all into the same directories etc. Initial problem. We want to run our tests whenever our main project is built. But adding a post build event to the web project that runs against the test project doesn't work because the web project doesn't reference the test project and won't trigger a build of this project. I could go on ... but that's enough ... We've spent about a week trying to make this work nicely but haven't succeeded. Feel free to edit this if you feel you can get a better response ...

• JOptionPane opening another JFrame

  - by mike_hornbeck

  So I'm continuing my fight with this : http://stackoverflow.com/questions/2923545/creating-java-dialogs/2926126 task. Now my JOptionPane opens new window with envelope overfiew, but I can't change size of this window. Also I wanted to have sender's data in upper left corner, and receiver's data in bottom right. How can I achieve that ? There is also issue with OptionPane itself. After I click 'OK' it opens small window in the upper left corner of the screen. What is this and why it's appearing ? My code: import java.awt.*; import java.awt.Font; import javax.swing.*; public class Main extends JFrame { private static JTextField nameField = new JTextField(20); private static JTextField surnameField = new JTextField(); private static JTextField addr1Field = new JTextField(); private static JTextField addr2Field = new JTextField(); private static JComboBox sizes = new JComboBox(new String[] { "small", "medium", "large", "extra-large" }); public Main(){ JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); getContentPane().add(mainPanel); JPanel addrPanel = new JPanel(new GridLayout(0, 1)); addrPanel.setBorder(BorderFactory.createTitledBorder("Receiver")); addrPanel.add(new JLabel("Name")); addrPanel.add(nameField); addrPanel.add(new JLabel("Surname")); addrPanel.add(surnameField); addrPanel.add(new JLabel("Address 1")); addrPanel.add(addr1Field); addrPanel.add(new JLabel("Address 2")); addrPanel.add(addr2Field); mainPanel.add(addrPanel); mainPanel.add(new JLabel(" ")); mainPanel.add(sizes); String[] buttons = { "OK", "Cancel"}; int c = JOptionPane.showOptionDialog( null, mainPanel, "My Panel", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); if(c ==0){ new Envelope(nameField.getText(), surnameField.getText(), addr1Field.getText() , addr2Field.getText(), sizes.getSelectedIndex()); } setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); pack(); setVisible(true); } public static void main(String[] args) { new Main(); } } class Envelope extends JFrame { private final int SMALL=0; private final int MEDIUM=1; private final int LARGE=2; private final int XLARGE=3; public Envelope(String n, String s, String a1, String a2, int i){ Container content = getContentPane(); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); mainPanel.add(new JLabel("John Doe")); mainPanel.add(new JLabel("FooBar str 14")); mainPanel.add(new JLabel("Newark, 45-99")); JPanel dataPanel = new JPanel(); dataPanel.setFont(new Font("sansserif", Font.PLAIN, 32)); //set size from i mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); mainPanel.setBackground(Color.ORANGE); mainPanel.add(new JLabel("Mr "+n+" "+s)); mainPanel.add(new JLabel(a1)); mainPanel.add(new JLabel(a2)); content.setSize(450, 600); content.setBackground(Color.ORANGE); content.add(mainPanel, BorderLayout.NORTH); content.add(dataPanel, BorderLayout.SOUTH); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); pack(); setVisible(true); } }

• Binary data from a serial port in linux using c

  - by user1680393

  I am reading binary data from a serial port on Phidget sbc using Linux to get a command from an application running on a PC. I wrote a test program in VB to read the data into a byte array and convert it to decimal to use it but can’t figure out how to do it in c. I am unable to come up with anything with the research I have done on the internet. Command sent from PC is 0x0F. To check if I am getting correct data I read the data and send it back. Here is what I get back. Returned data has a carriage return added to it. Hex Display 0F00 0000 0D ‘\’ Display \0F\00\00\00\r Normal display just display a strange character. This tells me that the data is there that I can use, but can’t figure out to extract the value 0F or 15. How can I convert the incoming data to use it? I tried converting the received data using strtol, but it returns 0. I also tried setting the port to raw but it did not make any difference. unsigned char buffer1[1]; int ReadPort1() { int result; result = read(file1, &buffer1,1); if(result > 0) { WritePort1(buffer1); sprintf(tempstr, "Port1 data %s %d", buffer1, result); DisplayText(2,tempstr); } return result; } Port Open/Setup void OpenPort1() { //file1 = open("/dev/ttyUSB1", O_RDWR | O_NOCTTY | O_NONBLOCK); file1 = open("/dev/ttyUSB1", O_RDWR | O_NOCTTY | O_NODELAY); if(file1 < 0) printf("Error opening serial port1.\n"); else { SetPort(file1, 115200, 8, 1, 0, 1); port1open = 1; } } void SetPort(int fd, int Baud_Rate, int Data_Bits, int Stop_Bits, int Parity, int raw) { long BAUD; // derived baud rate from command line long DATABITS; long STOPBITS; long PARITYON; long PARITY; struct termios newtio; switch (Baud_Rate) { case 115200: BAUD = B115200; break; case 38400: BAUD = B38400; break; case 19200: BAUD = B19200; break; case 9600: BAUD = B9600; break; } //end of switch baud_rate switch (Data_Bits) { case 8: default: DATABITS = CS8; break; case 7: DATABITS = CS7; break; case 6: DATABITS = CS6; break; case 5: DATABITS = CS5; break; } //end of switch data_bits switch (Stop_Bits) { case 1: default: STOPBITS = 0; break; case 2: STOPBITS = CSTOPB; break; } //end of switch stop bits switch (Parity) { case 0: default: //none PARITYON = 0; PARITY = 0; break; case 1: //odd PARITYON = PARENB; PARITY = PARODD; break; case 2: //even PARITYON = PARENB; PARITY = 0; break; } //end of switch parity newtio.c_cflag = BAUD | DATABITS | STOPBITS | PARITYON | PARITY | CLOCAL | CREAD; newtio.c_iflag = IGNPAR; if(raw == 1) { newtio.c_oflag &= ~OPOST; newtio.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG); } else { newtio.c_lflag = 0; //ICANON; newtio.c_oflag = 0; } newtio.c_cc[VMIN]=1; newtio.c_cc[VTIME]=0; tcflush(fd, TCIFLUSH); tcsetattr(fd,TCSANOW,&newtio); }

• Help to restructure my Doc/View more correctly

  - by Harvey

  Edited by OP. My program is in need of a lot of cleanup and restructuring. In another post I asked about leaving the MFC DocView framework and going to the WinProc & Message Loop way (what is that called for short?). Well at present I am thinking that I should clean up what I have in Doc View and perhaps later convert to non-MFC it that even makes sense. My Document class currently has almost nothing useful in it. I think a place to start is the InitInstance() function (posted below). In this part: POSITION pos=pDocTemplate->GetFirstDocPosition(); CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos); ASSERT_VALID(pDoc); POSITION vpos=pDoc->GetFirstViewPosition(); CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos); This seem strange to me. I only have one doc and one view. I feel like I am going about it backwards with GetNextDoc() and GetNextView(). To try to use a silly analogy; it's like I have a book in my hand but I have to look up in it's index to find out what page the Title of the book is on. I'm tired of feeling embarrassed about my code. I either need correction or reassurance, or both. :) Also, all the miscellaneous items are in no particular order. I would like to rearrange them into an order that may be more standard, structured or straightforward. ALL suggestions welcome! BOOL CLCWApp::InitInstance() { InitCommonControls(); if(!AfxOleInit()) return FALSE; // Initialize the Toolbar dll. (Toolbar code by Nikolay Denisov.) InitGuiLibDLL(); // NOTE: insert GuiLib.dll into the resource chain SetRegistryKey(_T("Real Name Removed")); // Register document templates CSingleDocTemplate* pDocTemplate; pDocTemplate = new CSingleDocTemplate( IDR_MAINFRAME, RUNTIME_CLASS(CLCWDoc), RUNTIME_CLASS(CMainFrame), RUNTIME_CLASS(CChildView)); AddDocTemplate(pDocTemplate); // Parse command line for standard shell commands, DDE, file open CCmdLineInfo cmdInfo; ParseCommandLine(cmdInfo); // Dispatch commands specified on the command line // The window frame appears on the screen in here. if (!ProcessShellCommand(cmdInfo)) { AfxMessageBox("Failure processing Command Line"); return FALSE; } POSITION pos=pDocTemplate->GetFirstDocPosition(); CLCWDoc *pDoc=(CLCWDoc *)pDocTemplate->GetNextDoc(pos); ASSERT_VALID(pDoc); POSITION vpos=pDoc->GetFirstViewPosition(); CChildView *pCV=(CChildView *)pDoc->GetNextView(vpos); if(!cmdInfo.m_Fn1.IsEmpty() && !cmdInfo.m_Fn2.IsEmpty()) { pCV->OpenF1(cmdInfo.m_Fn1); pCV->OpenF2(cmdInfo.m_Fn2); pCV->DoCompare(); // Sends a paint message when complete } // enable file manager drag/drop and DDE Execute open m_pMainWnd->DragAcceptFiles(TRUE); m_pMainWnd->ShowWindow(SW_SHOWNORMAL); m_pMainWnd->UpdateWindow(); // paints the window background pCV->bDoSize=true; //Prevent a dozen useless size calculations return TRUE; } Thanks

• Resizing Images In a Table Using JavaScript

  - by Abluescarab

  Hey, all. I apologize beforehand if none of this makes sense, or if I sound incompetent... I've been making webpages for a while, but don't know any JavaScript. I am trying to make a webpage for a friend, and he requested if I could write some code to resize the images in the page based on the user's screen resolution. I did some research on this question, and it's kind of similar to this, this, and this. Unfortunately, those articles didn't answer my question entirely because none of the methods described worked. Right now, I have a three-column webpage with 10 images in a table in the left sidebar, and when I use percentages for their sizes, they don't resize right between monitors. As such, I'm trying to write a JavaScript function that changes their sizes after detecting the screen resolution. The code is stripped from my post if I put it all, so I'll just say that each image links to a website and uses a separate image to change color when you hover over it. Would I have to address both images to change their sizes correctly? I use a JavaScript function to switch between them. Anyway, I tried both methods in this article and neither worked for me. If it helps, I'm using Google Chrome, but I'm trying to make this page as cross-browser as possible. Here's the code I have so far in my JavaScript function: function resizeImages() { var w = window.width; var h = window.height; var yuk = document.getElementById('yuk').style; var wb = document.getElementById('wb').style; var tf = document.getElementById('tf').style; var lh = document.getElementById('lh').style; var ko = document.getElementById('ko').style; var gz = document.getElementById('gz').style; var fb = document.getElementById('fb').style; var eg = document.getElementById('eg').style; var dl = document.getElementById('dl').style; var da = document.getElementById('da').style; if (w = "800" && h = "600") { } else if (w = "1024" && h = "768") { } else if (w = "1152" && h = "864") { } else if (w = "1280" && h = "720") { } else if (w = "1280" && h = "768") { } else if (w = "1280" && h = "800") { } else if (w = "1280" && h = "960") { } else if (w = "1280" && h = "1024") { } } Yeah, I don't have much in it because I don't know if I'm doing it right yet. Is this a way I can detect the "width" and "height" properties of a window? The "yuk", "wb", etcetera are the images I'm trying to change the size of. To sum it up: I want to resize images based on screen resolution using JavaScript, but my research attempts have been... futile. I'm sorry if that was long-winded, but thanks ahead of time!

• WPF Issues with Control Layout

  - by Brett Powell

  I am making an application that connects to our billing software using its API, and I am running into a few issues getting the layout working properly. I want to make it so that when one of the expanders is minimized, the other window fills the gap, and when it is expanded again the other expander goes back to where it was. Right now when the arrow is clicked on one, there is just an empty gap. I used a DockPanel as the parent which I assumed would automatically do this, but it isn't working. Second question, is there a way to make these areas resizable? I don't want to try and get too frisky with allowing the user to undock the menus (don't even know if that is possible with just straight WPF) but it would be nice if they could change the width/height of them. Also, just a newbie question to C#, but what is the equivalent of a C++ header file? It looks like you just use .cs files, but I am not sure. I want to extract all of my functions that pull the data from the billing software and put them into a different file to clean up the code. Here is my XAML... <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Billing Management" Height="550" Width="754" xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="22" /> <RowDefinition /> </Grid.RowDefinitions> <Menu Height="22" Name="menu1" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Top" HorizontalContentAlignment="Left" IsEnabled="True" IsMainMenu="True"> <MenuItem Header="_File"> <MenuItem Header="_Open" /> <MenuItem Header="_Close" /> <Separator/> <MenuItem Header="_Exit" /> </MenuItem> </Menu> <TabControl Name="tabControl1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderThickness="1" Padding="0" TabStripPlacement="Bottom" UseLayoutRounding="False" FlowDirection="LeftToRight" Grid.Row="1"> <TabItem Header="Main" Name="tabItem1" Margin="0"> <DockPanel Name="dockPanel1" LastChildFill="True"> <ListBox Height="100" Name="listBox3" DockPanel.Dock="Top" /> <ListBox Name="listBox4" Width="200" DockPanel.Dock="Right" /> <DockPanel Height="Auto" Name="dockPanel2" Width="Auto" VerticalAlignment="Stretch" LastChildFill="True"> <shared:AnimatedExpander Header="Staff Online" Width="200" Name="expanderStaffOnline" IsExpanded="True" Height="194" BorderThickness="0" DockPanel.Dock="Top" VerticalContentAlignment="Stretch"> <ListBox Name="listboxStaffOnline" Width="Auto" Height="Auto" Margin="0" VerticalAlignment="Stretch" Loaded="listboxStaffOnline_Loaded" /> </shared:AnimatedExpander> <shared:AnimatedExpander Header="Test Menu 2" Height="Auto" Name="animatedExpander1" BorderThickness="1" Margin="0,0,0,0" IsExpanded="True" VerticalContentAlignment="Stretch"> <ListBox Height="Auto" HorizontalAlignment="Stretch" Name="listBox6" VerticalAlignment="Stretch" Margin="0" BorderThickness="1" /> </shared:AnimatedExpander> </DockPanel> <ListBox Height="100" Name="listboxAdminLogs" DockPanel.Dock="Bottom" Loaded="listboxAdminLogs_Loaded" /> <ListBox Name="listBox5" /> </DockPanel> </TabItem> <TabItem Header="Support" Name="tabItem2" Margin="0"> </TabItem> <TabItem Header="Clients" /> <TabItem Header="Billing" /> <TabItem Header="Orders" /> </TabControl> </Grid> </Window>

• Issue getting camera emulation to work with Tom G's HttpCamera

  - by user591524

  I am trying to use the android emulator to preview video from webcam. I have used the tom gibara sample code, minus the webbroadcaster (i am instead using VLC streaming via http). So, I have modified the SDK's "CameraPreview" app to use the HttpCamera, but the stream never appears. Debugging through doesn't give me any clues either. I wonder if anything obvious is clear to others? The preview app launches and remains black. Notes: 1) I have updated the original CameraPreview class as described here: http://www.inter-fuser.com/2009/09/live-camera-preview-in-android-emulator.html, but referencing httpCamera instead of socketcamera. 2) I updated Tom's original example to reference "Camera" type instead of deprecated "CameraDevice" type. 3) Below is my CameraPreview.java. 4) THANK YOU package com.example.android.apis.graphics; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; import android.view.Window; import java.io.IOException; import android.graphics.Canvas; // ---------------------------------------------------------------------- public class CameraPreview extends Activity { private Preview mPreview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // Create our Preview view and set it as the content of our activity. mPreview = new Preview(this); setContentView(mPreview); } } // ---------------------------------------------------------------------- class Preview extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder mHolder; //Camera mCamera; HttpCamera mCamera;//changed Preview(Context context) { super(context); // Install a SurfaceHolder.Callback so we get notified when the // underlying surface is created and destroyed. mHolder = getHolder(); mHolder.addCallback(this); //mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); mHolder.setType(SurfaceHolder.SURFACE_TYPE_NORMAL);//changed } public void surfaceCreated(SurfaceHolder holder) { // The Surface has been created, acquire the camera and tell it where // to draw. //mCamera = Camera.open(); this.StartCameraPreview(holder); } public void surfaceDestroyed(SurfaceHolder holder) { // Surface will be destroyed when we return, so stop the preview. // Because the CameraDevice object is not a shared resource, it's very // important to release it when the activity is paused. //mCamera.stopPreview();//changed mCamera = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Now that the size is known, set up the camera parameters and begin // the preview. //Camera.Parameters parameters = mCamera.getParameters(); //parameters.setPreviewSize(w, h); //mCamera.setParameters(parameters); //mCamera.startPreview(); this.StartCameraPreview(holder); } private void StartCameraPreview(SurfaceHolder sh) { mCamera = new HttpCamera("10.213.74.247:443", 640, 480, true);//changed try { //mCamera.setPreviewDisplay(holder); Canvas c = sh.lockCanvas(null); mCamera.capture(c); sh.unlockCanvasAndPost(c); } catch (Exception exception) { //mCamera.release(); mCamera = null; // TODO: add more exception handling logic here } } }

• When Clearing an ObservableCollection, There are No Items in e.OldItems

  - by cplotts

  I have something here that is really catching me off guard. I have an ObservableCollection of T that is filled with items. I also have an event handler attached to the CollectionChanged event. When you Clear the collection it causes an CollectionChanged event with e.Action set to NotifyCollectionChangedAction.Reset. Ok, that's normal. But what is weird is that neither e.OldItems or e.NewItems has anything in it. I would expect e.OldItems to be filled with all items that were removed from the collection. Has anyone else seen this? And if so, how have they gotten around it? Some background: I am using the CollectionChanged event to attach and detach from another event and thus if I don't get any items in e.OldItems ... I won't be able to detach from that event. CLARIFICATION: I do know that the documentation doesn't outright state that it has to behave this way. But for every other action, it is notifying me of what it has done. So, my assumption is that it would tell me ... in the case of Clear/Reset as well. Below is the sample code if you wish to reproduce it yourself. First off the xaml: <Window x:Class="ObservableCollection.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" > <StackPanel> <Button x:Name="addButton" Content="Add" Width="100" Height="25" Margin="10" Click="addButton_Click"/> <Button x:Name="moveButton" Content="Move" Width="100" Height="25" Margin="10" Click="moveButton_Click"/> <Button x:Name="removeButton" Content="Remove" Width="100" Height="25" Margin="10" Click="removeButton_Click"/> <Button x:Name="replaceButton" Content="Replace" Width="100" Height="25" Margin="10" Click="replaceButton_Click"/> <Button x:Name="resetButton" Content="Reset" Width="100" Height="25" Margin="10" Click="resetButton_Click"/> </StackPanel> </Window> Next, the code behind: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Collections.ObjectModel; namespace ObservableCollection { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); _integerObservableCollection.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(_integerObservableCollection_CollectionChanged); } private void _integerObservableCollection_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) { switch (e.Action) { case System.Collections.Specialized.NotifyCollectionChangedAction.Add: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Move: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Remove: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Replace: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Reset: break; default: break; } } private void addButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Add(25); } private void moveButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Move(0, 19); } private void removeButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.RemoveAt(0); } private void replaceButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection[0] = 50; } private void resetButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Clear(); } private ObservableCollection<int> _integerObservableCollection = new ObservableCollection<int> { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 }; } }

• Looking for best practise for writing a serial device communication app in C#

  - by cdotlister

  I am pretty new to serial comms, but would like advise on how to best achieve a robust application which speak to and listens to a serial device. I have managed to make use of System.IO.serialport, and successfully connected to, sent data to and recieved from my device. The way things work is this. My application connects to the Com Port and opens the port.... I then connect my device to the com port, and it detects a connectio to the PC, so sends a bit of text. it's really just copyright info, as well as the version of the firmware. I don't do anything with that, except display it in my 'activity' window. The device then waits. I can then query information, but sending a command such as 'QUERY PARAMETER1'. It then replies with something like: 'QUERY PARAMETER1\r\n\r\n76767\r\n\r\n' I then process that. I can then update it by sending 'SET PARAMETER1 12345', and it will reply with 'QUERY PARAMETER1\r\n\r\n12345\r\n\r\n'. All pretty basic. So, what I have done is created a Communication Class. this call is called in it's own thread, and sends data back to the main form... and also allows me to send messages to it. Sending data is easy. Recieving is a bit more tricky. I have employed the use of the datarecieved event, and when ever data comes in, I echo that to my screen. My problem is this: When I send a command, I feel I am being very dodgy in my handling. What I am doing is, lets say I am sending 'QUERY PARAMETER1'. I send the command to the device, I then put 'PARAMETER1' into a global variable, and I do a Thread.Sleep(100). On the data recieved, I then have a bit of logic that checks the incoming data, and sees if the string CONTAINS the value in the gloabl variable. As the reply may be 'QUERY PARAMETER1\r\n\r\n76767\r\n\r\n', it sees that it contains my parameter, parses the string, and returns the value I am looking for, but placing it into another global variable. My sending method was sleeping for 100ms. It then wakes, and checks the returned global variable. If it has data... then I'm happy, and I process the data. Problem is... if the sleep is too short.. it will fail. And I feel it's flakey.. putting stuff into variables.. then waiting... The other option is to use ReadLine instead, but that's very blocking. So I remove the datarecieved method, and instead... just send the data... then call ReadLine(). That may give me better results. There's no time, except when we connect initially, that data comes from the device, without me requesting it. So, maybe readline will be simpler and safer? Is this known as 'Blocking' reads? Also, can I set a timeout? Hopefully someone can guide me.

• Element.appendChild() hosed in IE .. workaround? (related to innerText vs textContent)

  - by Rowe Morehouse

  I've heard that using el.innerText||el.textContent can yield unreliable cross-browswer results, so I'm walking the DOM tree to collect text nodes recursively, and write them into tags in the HTML body. What this script does is read hash substring valus from the window.location and write them into the HTML. This script is working for me in Chrome & Firefox, but choking in IE. I call the page with an URL syntax like this: http://example.com/pagename.html#dyntext=FOO&dynterm=BAR&dynimage=FRED UPDATE UPDATE UPDATE Solution: I moved the scripts to before </body> (where they should have been) then removed console.log(sPageURL); and now it's working in Chrome, Firefox, IE8 and IE9. This my workaround for the innerText vs textContent crossbrowser issue when you are just placing text rather than getting text. In this case, getting hash substring values from the window.location and writing them into the page. <html> <body> <span id="dyntext-span" style="font-weight: bold;"></span><br /> <span id="dynterm-span" style="font-style: italic;"></span><br /> <span id="dynimage-span" style="text-decoration: underline;"></span><br /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script> <script> $(document).ready(function() { var tags = ["dyntext", "dynterm", "dynimage"]; for (var i = 0; i < tags.length; ++i) { var param = GetURLParameter(tags[i]); if (param) { var dyntext = GetURLParameter('dyntext'); var dynterm = GetURLParameter('dynterm'); var dynimage = GetURLParameter('dynimage'); } } var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage); elem.appendChild(text); }); function GetURLParameter(sParam) { var sPageURL = window.location.hash.substring(1); var sURLVariables = sPageURL.split('&'); for (var i = 0; i < sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } </script> </body> </html> FINAL UPDATE If your hash substring values require spaces (like a linguistic phrase with three words, for example) then separate the words with the + character in your URI, and replace the unicode \u002B character with a space when you create each text node, like this: var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage.replace(/\u002B/g, " ")); elem.appendChild(text); Now form your URI like this: http://example.com/pagename.html#dyntext=FOO+MAN+CHU&dynterm=BAR+HOPPING&dynimage=FRED+IS+DEAD

• SetPixelFormat is not creating an alpha channel for OpenGL

  - by i_photon

  I've been able to do this before, and I don't know what changed between two weeks ago and the last windows update, but for some reason SetPixelFormat isn't creating an alpha channel. gDebugger shows that the window's back buffer only has 3 channels. White+0 alpha renders as white. So there is something inherently wrong with what I was doing, or an update broke it. The code below should be paste-able into an empty VS project. #include <Windows.h> #include <dwmapi.h> #include <gl/GL.h> #pragma comment(lib,"opengl32.lib") #pragma comment(lib,"dwmapi.lib") HWND hWnd = 0; HDC hDC = 0; HGLRC hRC = 0; LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM); int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow ) { WNDCLASSEX wcex = {0}; wcex.cbSize = sizeof(WNDCLASSEX); wcex.lpfnWndProc = WndProc; wcex.hCursor = LoadCursor(NULL, IDC_ARROW); wcex.lpszClassName = TEXT("why_class"); RegisterClassEx(&wcex); // no errors hWnd = CreateWindowEx( NULL, TEXT("why_class"), TEXT("why_window"), WS_OVERLAPPEDWINDOW, 128,128, 256,256, NULL, NULL, hInstance, NULL ); // no errors PIXELFORMATDESCRIPTOR pfd = {0}; pfd.nSize = sizeof(pfd); pfd.nVersion = 1; pfd.dwFlags = PFD_DRAW_TO_WINDOW| PFD_SUPPORT_OPENGL| PFD_DOUBLEBUFFER| PFD_SUPPORT_COMPOSITION; pfd.cColorBits = 32; pfd.cAlphaBits = 8; // need an alpha channel pfd.cDepthBits = 24; pfd.cStencilBits = 8; hDC = GetDC(hWnd); int i = ChoosePixelFormat(hDC,&pfd); SetPixelFormat(hDC,i,&pfd); // no errors hRC = wglCreateContext(hDC); // no errors wglMakeCurrent(hDC,hRC); // no errors // EDIT: Turn on alpha testing (which actually won't // fix the clear color problem below) glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA); // EDIT: Regardless of whether or not GL_BLEND is enabled, // a clear color with an alpha of 0 should (or did at one time) // make this window transparent glClearColor( 0,0,0, // if this is (1,1,1), the window renders // solid white regardless of the alpha 0 // changing the alpha here has some effect ); DWM_BLURBEHIND bb = {0}; bb.dwFlags = DWM_BB_ENABLE|DWM_BB_TRANSITIONONMAXIMIZED; bb.fEnable = TRUE; bb.fTransitionOnMaximized = TRUE; DwmEnableBlurBehindWindow(hWnd,&bb); // no errors ShowWindow(hWnd, SW_SHOWNORMAL); UpdateWindow(hWnd); // no errors MSG msg = {0}; while(true){ GetMessage(&msg,NULL,NULL,NULL); if(msg.message == WM_QUIT){ return (int)msg.wParam; } TranslateMessage(&msg); DispatchMessage(&msg); glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glBegin(GL_TRIANGLES); // this vertex should be transparent, // as it was when I last built this test // // it renders as white glColor4f(1,1,1,0); glVertex2f(0,0); glColor4f(0,1,1,1); glVertex2f(1,0); glColor4f(1,0,1,1); glVertex2f(0,1); glEnd(); SwapBuffers(hDC); } return (int)msg.wParam; } LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { switch (message) { case WM_DESTROY: { PostQuitMessage(0); }return 0; default: break; } return DefWindowProc(hWnd, message, wParam, lParam); }

• Looking for best practise for writing a serial device communication app

  - by cdotlister

  I am pretty new to serial comms, but would like advise on how to best achieve a robust application which speak to and listens to a serial device. I have managed to make use of System.IO.SerialPort, and successfully connected to, sent data to and recieved from my device. The way things work is this. My application connects to the Com Port and opens the port.... I then connect my device to the com port, and it detects a connection to the PC, so sends a bit of text. it's really just copyright info, as well as the version of the firmware. I don't do anything with that, except display it in my 'activity' window. The device then waits. I can then query information, but sending a command such as 'QUERY PARAMETER1'.

• Problem with the output of Jquery function .offset in IE

  - by vandalk

  Hello! I'm new to jquery and javascript, and to web site developing overall, and I'm having a problem with the .offset function. I have the following code working fine on chrome and FF but not working on IE: $(document).keydown(function(k){ var keycode=k.which; var posk=$('html').offset(); var centeryk=screen.availHeight*0.4; var centerxk=screen.availWidth*0.4; $("span").text(k.which+","+posk.top+","+posk.left); if (keycode==37){ k.preventDefault(); $("html,body").stop().animate({scrollLeft:-1*posk.left-centerxk}) }; if (keycode==38){ k.preventDefault(); $("html,body").stop().animate({scrollTop:-1*posk.top-centeryk}) }; if (keycode==39){ k.preventDefault(); $("html,body").stop().animate({scrollLeft:-1*posk.left+centerxk}) }; if (keycode==40){ k.preventDefault(); $("html,body").stop().animate({scrollTop:-1*posk.top+centeryk}) }; }); hat I want it to do is to scroll the window a set percentage using the arrow keys, so my thought was to find the current coordinates of the top left corner of the document and add a percentage relative to the user screen to it and animate the scroll so that the content don't jump and the user looses focus from where he was. The $("span").text are just so I know what's happening and will be turned into comments when the code is complete. So here is what happens, on Chrome and Firefox the output of the $("span").text for the position variables is correct, starting at 0,0 and always showing how much of the content was scrolled in coordinates, but on IE it starts on -2,-2 and never gets out of it, even if I manually scroll the window until the end of it and try using the right arrow key it will still return the initial value of -2,-2 and scroll back to the beggining. I tried substituting the offset for document.body.scrollLetf and scrollTop but the result is the same, only this time the coordinates are 0,0. Am I doing something wrong? Or is this some IE bug? Is there a way around it or some other function I can use and achieve the same results? On another note, I did other two navigating options for the user in this section of the site, one is to click and drag anywhere on the screen to move it: $("html").mousedown(function(e) { var initx=e.pageX var inity=e.pageY $(document).mousemove(function(n) { var x_inc= initx-n.pageX; var y_inc= inity-n.pageY; window.scrollBy(x_inc*0.7,y_inc*0.7); initx=n.pageX; inity=n.pageY //$("span").text(initx+ "," +inity+ "," +x_inc+ "," +y_inc+ "," +e.pageX+ "," +e.pageY+ "," +n.pageX+ "," +n.pageY); // cancel out any text selections document.body.focus(); // prevent text selection in IE document.onselectstart = function () { return false; }; // prevent IE from trying to drag an image document.ondragstart = function() { return false; }; // prevent text selection (except IE) return false; }); }); $("html").mouseup(function() { $(document).unbind('mousemove'); }); The only part of this code I didn't write was the preventing text selection lines, these ones I found in a tutorial about clicking and draging objects, anyway, this code works fine on Chrome, FireFox and IE, though on Firefox and IE it's more often to happen some moviment glitches while you drag, sometimes it seems the "scrolling" is a litlle jagged, it's only a visual thing and not that much significant but if there's a way to prevent it I would like to know.

• Landscape-only orientation + view controllers: What am I still missing?

  - by mahboudz

  Hi. I can't believe I am still having problems with screen orientation, now on the iPad. This is an app that only supports one of the two landscape orientation. In my info.plist, I include: <string>UIInterfaceOrientationLandscapeRight</string> <string>UIInterfaceOrientationLandscapeLeft</string> In Interface Builder, all my views are created in landscape orientation. Only the main Window is not, but I don't see a way to change that. When launched, I get the following coordinates for my main window and the main viewcontroller view: Window frame {{0, 0}, {768, 1024}} mainView frame {{0, 0}, {748, 1024}} (Changing the frame at runtime to be what I expect, does not change the odd behavior.) All other views after that show these coordinates when summoned (when loaded but before being presented): frame of keysig {{0, 0}, {1024, 768}} frame of instrumentSelect {{20, 0}, {1024, 768}} frame of settings {{0, 0}, {467, 300}} In all my viewControllers, i respond to shouldAutorotateToInterfaceOrientation with: return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight)); In my app, everything (almost) functions as expected. The app launches into one of the two landscape modes. The views (and viewcontrollers) display everything where it belongs, taps work all across the screen, as expected. However, there are two clues that something is still wrong. Clue #1: I have two viewcontrollers that are UITabeViewControllers. When summoned, they are supposed to open up their views and scroll to the selected row of the table. However it is evident that they scroll, but they don't scroll down far enough. It seems that they think that the screen extends further down and they scroll just enough to move the row to a place near the bottom of the screen, but that location is not visible. When the views are loaded, the coordinates are: frame of keysig {{0, 0}, {1024, 768}} frame of instrumentSelect {{20, 0}, {1024, 768}} When I present them using a popover, the frames get resized to: frame of keysig {{0, 0}, {320, 655}} frame of instrumentSelect {{0, 0}, {320, 655}} The frame of the viewController that does the presentation, same mainView frame mentioned above is: frame of self {{20, 0}, {748, 1024}} I have also tried to accomplish the same thing with presentModalViewController instead of presentPopover, and have the same results. This is what the popovers look like: In both cases, the selected row is below the horizon, even though the tableView did visibly scroll in order to make the row visible. I am not sure what to try next. I checked each UITable's scrollView content coordinates and they seemed reasonable. It almost seems like a UITable internal rect gets created with the wrong number and stays that way. Clue #2: All my actionsheets come up with a width of 320. I can only assume that the iPad allows actionSheets in only 320 or 480 widths and since it somehow thinks that the screen is oriented in portrait mode, and then uses the narrower width. There you have it. I can't believe I am still getting hung up on orientation issues. I swear Apple doesn't make it easy to have a landscape app. Any ideas?

• wpf custom control problem

  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

• Why does this Java code not utilize all CPU cores?

  - by ReneS

  The attached simple Java code should load all available cpu core when starting it with the right parameters. So for instance, you start it with java VMTest 8 int 0 and it will start 8 threads that do nothing else than looping and adding 2 to an integer. Something that runs in registers and not even allocates new memory. The problem we are facing now is, that we do not get a 24 core machine loaded (AMD 2 sockets with 12 cores each), when running this simple program (with 24 threads of course). Similar things happen with 2 programs each 12 threads or smaller machines. So our suspicion is that the JVM (Sun JDK 6u20 on Linux x64) does not scale well. Did anyone see similar things or has the ability to run it and report whether or not it runs well on his/her machine (= 8 cores only please)? Ideas? I tried that on Amazon EC2 with 8 cores too, but the virtual machine seems to run different from a real box, so the loading behaves totally strange. package com.test; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.Future; import java.util.concurrent.TimeUnit; public class VMTest { public class IntTask implements Runnable { @Override public void run() { int i = 0; while (true) { i = i + 2; } } } public class StringTask implements Runnable { @Override public void run() { int i = 0; String s; while (true) { i++; s = "s" + Integer.valueOf(i); } } } public class ArrayTask implements Runnable { private final int size; public ArrayTask(int size) { this.size = size; } @Override public void run() { int i = 0; String[] s; while (true) { i++; s = new String[size]; } } } public void doIt(String[] args) throws InterruptedException { final String command = args[1].trim(); ExecutorService executor = Executors.newFixedThreadPool(Integer.valueOf(args[0])); for (int i = 0; i < Integer.valueOf(args[0]); i++) { Runnable runnable = null; if (command.equalsIgnoreCase("int")) { runnable = new IntTask(); } else if (command.equalsIgnoreCase("string")) { runnable = new StringTask(); } Future<?> submit = executor.submit(runnable); } executor.awaitTermination(1, TimeUnit.HOURS); } public static void main(String[] args) throws InterruptedException { if (args.length < 3) { System.err.println("Usage: VMTest threadCount taskDef size"); System.err.println("threadCount: Number 1..n"); System.err.println("taskDef: int string array"); System.err.println("size: size of memory allocation for array, "); System.exit(-1); } new VMTest().doIt(args); } }

Following is the code to Form load and save button: private void Form1_Load(object sender, EventArgs e) { SetComb(); connectionString = ConfigurationManager.AppSettings["connectionString"]; sqlConnection = new SqlConnection(connectionString); String sqlSelect = "Select OrderID, CustomerID, OrderDate, ShippedDate from Orders"; sqlDataMaster = new SqlDataAdapter(sqlSelect, sqlConnection); sqlConnection.Open(); //=============================================================================== //--- Set up the INSERT Command //=============================================================================== sInsProcName = "prInsert_Order"; insertcommand = new SqlCommand(sInsProcName, sqlConnection); insertcommand.CommandType = CommandType.StoredProcedure; insertcommand.Parameters.Add(new SqlParameter("@nNewID", SqlDbType.Int, 0, ParameterDirection.Output, false, 0, 0, "OrderID", DataRowVersion.Default, null)); insertcommand.UpdatedRowSource = UpdateRowSource.OutputParameters; insertcommand.Parameters.Add(new SqlParameter("@sCustomerID", SqlDbType.NChar, 5,"CustomerID")); insertcommand.Parameters["@sCustomerID"].Value = cmbCust.SelectedValue; insertcommand.Parameters.Add(new SqlParameter("@dtOrderDate", SqlDbType.DateTime, 8,"OrderDate")); insertcommand.Parameters["@dtOrderDate"].Value = dtOrdDt.Text; insertcommand.Parameters.Add(new SqlParameter("@dtShipDate", SqlDbType.DateTime, 8,"ShippedDate")); insertcommand.Parameters["@dtShipDate"].Value = dtShipDt.Text; sqlDataMaster.InsertCommand = insertcommand; //=============================================================================== //--- Set up the UPDATE Command //=============================================================================== sUpdProcName = "prUpdate_Order"; updatecommand = new SqlCommand(sUpdProcName, sqlConnection); updatecommand.CommandType = CommandType.StoredProcedure; updatecommand.Parameters.Add(new SqlParameter("@nOrderID", SqlDbType.Int, 4, "OrderID")); updatecommand.Parameters.Add(new SqlParameter("@dtOrderDate", SqlDbType.DateTime, 8, "OrderDate")); updatecommand.Parameters.Add(new SqlParameter("@dtShipDate", SqlDbType.DateTime, 8, "ShippedDate")); sqlDataMaster.UpdateCommand = updatecommand; //=============================================================================== //--- Set up the DELETE Command //=============================================================================== sDelProcName = "prDelete_Order"; deletecommand = new SqlCommand(sDelProcName, sqlConnection); deletecommand.CommandType = CommandType.StoredProcedure; deletecommand.Parameters.Add(new SqlParameter("@nOrderID", SqlDbType.Int, 4, "OrderID")); sqlDataMaster.DeleteCommand = deletecommand; dt = new DataTable(); sqlDataMaster.FillSchema(dt, SchemaType.Source); ds = new DataSet(); ds.Tables.Add(dt); bs = new BindingSource(); bs.DataSource = ds.Tables[0]; } public void SetComb() { cmbCust.DataSource = dm.GetData("Select * from Customers order by CompanyName"); cmbCust.DisplayMember = "CompanyName"; cmbCust.ValueMember = "CustomerId"; cmbCust.Text = ""; } private void btnSave_Click(object sender, EventArgs e) { sqlDataMaster.Update((DataTable) bs.DataSource); } and Stored Procedures for Insert/Update/Delete set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[prInsert_Order] -- ALTER PROCEDURE prInsert_Order @sCustomerID CHAR(5), @dtOrderDate DATETIME, @dtShipDate DATETIME, @nNewID INT OUTPUT AS SET NOCOUNT ON INSERT INTO Orders (CustomerID, OrderDate, ShippedDate) VALUES (@sCustomerID, @dtOrderDate, @dtShipDate) SELECT @nNewID = SCOPE_IDENTITY() set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[prUpdate_Order] -- ALTER PROCEDURE prUpdate_Order @nOrderID INT, @dtOrderDate DATETIME, @dtShipDate DATETIME AS UPDATE Orders SET OrderDate = @dtOrderDate, ShippedDate = @dtShipDate WHERE OrderID = @nOrderID set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[prDelete_Order] -- ALTER PROCEDURE prDelete_Order @nOrderID INT AS DELETE Orders WHERE OrderID = @nOrderID In the form CustomerID is selected via combobox which has Display property of CustomerName and Value property of CustomerID. But when clicking save button it shows no error, but it also don't save anything in Orders Table of Northwind....dm.GetData is the method of my Data Access Layer class to just get the info and populate CustomerID combobox. Any help with the code is highly appreciated... Thanks Ahmed

• JQuery Slide Onclick

  - by everreadyeddy

  I am using the code in example http://www.faridesign.net/2012/05/create-a-awesome-vertical-tabbed-content-area-using-css3-jquery/ I am trying to slide the div tags on a button click on the list so the current tab-content will slide in and the tab just clicked will slide out. I currently have the working example where I can switch between divs fine, but I need to slide in and out between divs. Is there any script I can do this with the current code. using .slide or .effect instead of .show() looks to display two divs at the same time. I'm not sure what I am doing wrong. <div id="v-nav"> <ul> <li tab="tab1" class="first current">Main Screen</li> <li tab="tab2">Div 1</li> <li tab="tab3">Div 2</li> <li tab="tab4">Div 3</li> <li tab="tab5">Div 4</li> <li tab="tab6">Div 5</li> <li tab="tab7">Div 6</li> <li tab="tab8" class="last">Div 7</li> </ul> <div class="tab-content"> <h4>Main Screen</h4> </div> <div class="tab-content"> <h4>Div 1</h4> </div> <div class="tab-content"> <h4>Div 2</h4> </div> <div class="tab-content"> <h4>Div 3</h4> </div> <div class="tab-content"> <h4>Div 4</h4> </div> <div class="tab-content"> <h4>Div 5</h4> </div> <div class="tab-content"> <h4>Div 6</h4> </div> <div class="tab-content"> <h4>Div 7</h4> </div> My Script looks like $(function () { var items = $('#v-nav>ul>li').each(function () { $(this).click(function () { //remove previous class and add it to clicked tab items.removeClass('current'); $(this).addClass('current'); //hide all content divs and show current one //$('#v-nav>div.tab-content').hide().eq(items.index($(this))).show(); //$('#v-nav>div.tab-content').hide().eq(items.index($(this))).fadeIn(100); $('#v-nav>div.tab-content').hide().eq(items.index($(this))).slideToggle(); window.location.hash = $(this).attr('tab'); }); }); if (location.hash) { showTab(location.hash); } else { showTab("tab1"); } function showTab(tab) { $("#v-nav ul li:[tab*=" + tab + "]").click(); } // Bind the event hashchange, using jquery-hashchange-plugin $(window).hashchange(function () { showTab(location.hash.replace("#", "")); }) // Trigger the event hashchange on page load, using jquery-hashchange-plugin $(window).hashchange(); });

• "FOR UPDATE" v/s "LOCK IN SHARE MODE" : Allow concurrent threads to read updated "state" value of locked row

  - by shadesco

  I have the following scenario: User X logs in to the application from location lc1: call it Ulc1 User X (has been hacked, or some friend of his knows his login credential, or he just logs in from a different browser on his machine,etc.. u got the point) logs in at the same time from location lc2: call it Ulc2 I am using a main servlet which : - gets a connection from database pooling - sets autocommit to false - executes a command that goes through app layers: if all successful, set autocommit to true in a "finally" statement, and closes connection. Else if an exception happens, rollback(). In my database (mysql/innoDb) i have a "history" table, with row columns: id(primary key) |username | date | topic | locked The column "locked" has by default value "false" and it serves as a flag that marks if a specific row is locked or not. Each row is specific to a user (as u can see from the username column) So back to the scenario: --Ulc1 sends the command to update his history from the db for date "D" and topic "T". --Ulc2 sends the same command to update history from the db for the same date "D" and same topic "T" at the exact same time. I want to implement an mysql/innoDB locking system that will enable whichever thread arriving to do the following check: Is column "locked" for this row true or not? if true, return a message to the user that " he is already updating the same data from another location" if not true (ie not locked) : flag it as locked and update then reset locked to false once finished. Which of these two mysql locking techniques, will actually allow the 2nd arriving thread from reading the "updated" value of the locked column to decide wt action to take?Should i use "FOR UPDATE" or "LOCK IN SHARE MODE"? This scenario explains what i want to accomplish: - Ulc1 thread arrives first: column "locked" is false, set it to true and continue updating process - Ulc2 thread arrives while Ulc1's transaction is still in process, and even though the row is locked through innoDb functionalities, it doesn't have to wait but in fact reads the "new" value of column locked which is "true", and so doesn't in fact have to wait till Ulc1 transaction commits to read the value of the "locked" column(anyway by that time the value of this column will already have been reset to false). I am not very experienced with the 2 types of locking mechanisms, what i understand so far is that LOCK IN SHARE MODE allow other transaction to read the locked row while FOR UPDATE doesn't even allow reading. But does this read gets on the updated value? or the 2nd arriving thread has to wait the first thread to commit to then read the value? Any recommendations about which locking mechanism to use for this scenario is appreciated. Also if there's a better way to "check" if the row has been locked (other than using a true/false column flag) please let me know about it. thank you SOLUTION (Jdbc pseudocode example based on @Darhazer's answer) Table : [ id(primary key) |username | date | topic | locked ] connection.setautocommit(false); //transaction-1 PreparedStatement ps1 = "Select locked from tableName for update where id="key" and locked=false); ps1.executeQuery(); //transaction 2 PreparedStatement ps2 = "Update tableName set locked=true where id="key"; ps2.executeUpdate(); connection.setautocommit(true);// here we allow other transactions threads to see the new value connection.setautocommit(false); //transaction 3 PreparedStatement ps3 = "Update tableName set aField="Sthg" where id="key" And date="D" and topic="T"; ps3.executeUpdate(); // reset locked to false PreparedStatement ps4 = "Update tableName set locked=false where id="key"; ps4.executeUpdate(); //commit connection.setautocommit(true);

• I never really understood: what is Application Binary Interface (ABI)?

  - by claws

  I never clearly understood what is an ABI. I'm sorry for such a lengthy question. I just want to clearly understand things. Please don't point me to wiki article, If could understand it, I wouldn't be here posting such a lengthy post. This is my mindset about different interfaces: TV remote is an interface between user and TV. It is an existing entity but useless (doesn't provide any functionality) by itself. All the functionality for each of those buttons on the remote is implemented in the Television set. Interface: It is a "existing entity" layer between the functionality and consumer of that functionality. An, interface by itself is doesn't do anything. It just invokes the functionality lying behind. Now depending on who the user is there are different type of interfaces. Command Line Interface(CLI) commands are the existing entities, consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: commands consumer: user Graphical User Interface(GUI) window,buttons etc.. are the existing entities, again consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: window,buttons etc.. consumer: user Application Programming Interface(API) functions or to be more correct, interfaces (in interfaced based programming) are the existing entities, consumer here is another program not a user. and again functionality lies behind this layer. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: functions, Interfaces(array of functions). consumer: another program/application. Application Binary Interface (ABI) Here is my problem starts. functionality: ??? existing entities: ??? consumer: ??? I've wrote few softwares in different languages and provided different kind of interfaces (CLI, GUI, API) but I'm not sure, if I ever, provided any ABI. http://en.wikipedia.org/wiki/Application_binary_interface says: ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; Other ABIs standardize details such as the C++ name mangling,[2] . exception propagation,[3] and calling convention between compilers on the same platform, but do not require cross-platform compatibility. Who needs these details? Please don't say, OS. I know assembly programming. I know how linking & loading works. I know what exactly happens inside. Where did C++ name mangling come in between? I thought we are talking at the binary level. Where did languages come in between? anyway, I've downloaded the [PDF] System V Application Binary Interface Edition 4.1 (1997-03-18) to see what exactly it contains. Well, most of it didn't make any sense. Why does it contain 2 chapters (4th & 5th) which describe the ELF file format.Infact, these are the only 2 significant chapters that specification. Rest of all the chapters "Processor Specific". Anyway, I thought that it is completely different topic. Please don't say that ELF file format specs are the ABI. It doesn't qualify to be Interface according to the definition. I know, since we are talking at such low level it must be very specific. But I'm not sure how is it "Instruction Set Architecture(ISA)" specific? Where can I find MS Window's ABI? So, these are the major queries that are bugging me.

  I know that there are a lot of questions somewhat related to this one, but they answers are a bit hard for me to make sense of. I'm receiving the following error for a few different lines of code: C:\Users\Jeff\AppData\Local\Temp\ccAixtmT.o:football.cpp:(.text+0x6f0): undefined reference to `Player::set_values(int, std::string, float)' From these blocks of code: class Player { int playerNum; string playerPos; float playerRank; public: void set_values(int, string, float); float get_rank(){ return playerRank; }; bool operator == (const Player &p1/*, const Player &p2*/) const { if(&p1.playerNum == &playerNum && &p1.playerPos == &playerPos && &p1.playerRank == &playerRank) return true; else return false; }; }; And this being the main function referencing the subclass: int main() { ifstream infile; infile.open ("input.txt", ifstream::in); int numTeams; string command; while(!infile.fail() && !infile.eof()){ infile >> numTeams; string name; Player p; int playNum; string playPos; float playRank; Player all[11]; float ranks[11]; Team allTeams[numTeams]; for(int i=0; i<numTeams; i++){ infile >> name; for(int j=0; j<11; j++){ infile >> playNum; infile >> playPos; infile >> playRank; if(playPos == "QB") p.set_values(playNum, playPos, (playRank*2.0)); else if(playPos == "RB") p.set_values(playNum, playPos, (playRank*1.5)); else if(playPos == "WR") p.set_values(playNum, playPos, (playRank/1.8)); else if(playPos == "TE") p.set_values(playNum, playPos, (playRank*1.1)); else if(playPos == "GD") p.set_values(playNum, playPos, (playRank/2.0)); else if(playPos == "TC") p.set_values(playNum, playPos, (playRank/2.2)); else if(playPos == "CR") p.set_values(playNum, playPos, (playRank/1.2)); all[j] = p; allTeams[i].set_values(all, name); } } infile >> command; if (command == "play"){ int t1; int t2; infile >> t1; infile >> t2; play(allTeams[t1], allTeams[t2]); } else { int t1; int p1; int t2; int p2; swap(allTeams[t1], allTeams[t1].get_player(p1), allTeams[t2], allTeams[t2].get_player(p2)); } } }

• about getadrrinfo() C++?

  - by Isavel

  I'm reading this book called beej's guide to network programming and there's a part in the book were it provide a sample code which illustrate the use of getaddrinfo(); the book state that the code below "will print the IP addresses for whatever host you specify on the command line" - beej's guide to network programming. now I'm curious and want to try it out and run the code, but I guess the code was develop in UNIX environment and I'm using visual studio 2012 windows 7 OS, and most of the headers was not supported so I did a bit of research and find out that I need to include the winsock.h and ws2_32.lib for windows, for it to get working, fortunately everything compiled no errors, but when I run it using the debugger and put in 'www.google.com' as command argument I was disappointed that it did not print any ipaddress, the output that I got from the console is "getaddrinfo: E" what does the letter E mean? Do I need to configure something out of the debugger? Interestingly I left the command argument blank and the output changed to "usage: showip hostname" Any help would be appreciated. #ifdef _WIN32 #endif #include <sys/types.h> #include <winsock2.h> #include <ws2tcpip.h> #include <iostream> using namespace std; #include <stdio.h> #include <string.h> #include <sys/types.h> #include <winsock.h> #pragma comment(lib, "ws2_32.lib") int main(int argc, char *argv[]) { struct addrinfo hints, *res, *p; int status; char ipstr[INET6_ADDRSTRLEN]; if (argc != 2) { fprintf(stderr,"usage: showip hostname\n"); system("PAUSE"); return 1; } memset(&hints, 0, sizeof hints); hints.ai_family = AF_UNSPEC; // AF_INET or AF_INET6 to force version hints.ai_socktype = SOCK_STREAM; if ((status = getaddrinfo(argv[1], NULL, &hints, &res)) != 0) { fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(status)); system("PAUSE"); return 2; } printf("IP addresses for %s:\n\n", argv[1]); for(p = res;p != NULL; p = p->ai_next) { void *addr; char *ipver; // get the pointer to the address itself, // different fields in IPv4 and IPv6: if (p->ai_family == AF_INET) { // IPv4 struct sockaddr_in *ipv4 = (struct sockaddr_in *)p->ai_addr; addr = &(ipv4->sin_addr); ipver = "IPv4"; } else { // IPv6 struct sockaddr_in6 *ipv6 = (struct sockaddr_in6 *)p->ai_addr; addr = &(ipv6->sin6_addr); ipver = "IPv6"; } // convert the IP to a string and print it: inet_ntop(p->ai_family, addr, ipstr, sizeof ipstr); printf(" %s: %s\n", ipver, ipstr); } freeaddrinfo(res); // free the linked list system("PAUSE"); return 0; }
