  • Sending Email through Gmail

    I am writing a program that send an email through GMail but I have serious Operation timeout error. What is the likely cause. class Mailer { MailMessage ms; SmtpClient Sc; public Mailer() { Sc = new SmtpClient("smtp.gmail.com"); //Sc.Credentials = CredentialCache.DefaultNetworkCredentials; Sc.EnableSsl = true; Sc.Port =465; Sc.Timeout = 900000000; Sc.DeliveryMethod = SmtpDeliveryMethod.Network; Sc.UseDefaultCredentials = false; Sc.Credentials = new NetworkCredential("uid", "mypss"); } public void MailTodaysBirthdays(List<Celebrant> TodaysCelebrant) { int i = TodaysCelebrant.Count(); foreach (Celebrant cs in TodaysCelebrant) { //if (IsEmail(cs.EmailAddress.ToString().Trim())) //{ ms = new MailMessage(); ms.To.Add(cs.EmailAddress); ms.From = new MailAddress("uid","Developers",System.Text.Encoding.UTF8); ms.Subject = "Happy Birthday "; String EmailBody = "Happy Birthday " + cs.FirstName; ms.Body = EmailBody; ms.Priority = MailPriority.High; try { Sc.Send(ms); } catch (Exception ex) { Sc.Send(ms); BirthdayServices.LogEvent(ex.Message.ToString(),EventLogEntryType.Error); } //} } } }

  • Fluent NHibernate auto mapping: map property from another table's column

    - by queen3
    I'm trying to use S#arp architecture... which includes Fluent NHibernate I'm newbie with (and with NHibernate too, frankly speaking). Auto mapping is used. So I have this: public class UserAction : Entity { public UserAction() { } [DomainSignature] [NotNull, NotEmpty] public virtual string Name { get; set; } [NotNull, NotEmpty] public virtual string TypeName { get; private set; } } public class UserActionMap : IAutoMappingOverride<UserAction> { public void Override(AutoMap<UserAction> mapping) { mapping.WithTable("ProgramComponents", m => m.Map(x => x.TypeName)); } } Now, table UserActions references table ProgramComponents (many to one) and I want property UserAction.TypeName to have value from db field ProgramComponents.TypeName. However, the above code fails with NHibernate.MappingException: Duplicate property mapping of TypeName found in OrderEntry3.Core.UserAction As far as I understand the problem is that TypeName is already auto-mapped... but I haven't found a way to remove the automatic mapping. Actually I think that my WithTable/Map mapping has to replace the automatic TypeName mapping, but seems like it does not. I also tried different mapping (names are different but that's all the same): mapping.WithTable("ProgramComponents", m => m.References<ProgramComponent>( x => x.Selector, "ProductSelectorID" ) and still get the same error. I can overcome this with mapping.HasOne<ProgramComponent>(x => x.Selector); but that's not what I exactly wants to do. And I still wonder why the first two methods do not work. I suspect this is because of WithTable.

  • Get the value for a WPF binding

    - by Jose
    Ok, I didn't want a bunch of ICommands in my MVVM ViewModels so I decided to create a MarkupExtension for WPF that you feed it a string(the name of the method), and it gives you back an ICommand that executes the method. here's a snippet: public class MethodCall : MarkupExtension { public MethodCall(string methodName) { MethodName = methodName; CanExecute = "Can" + methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { Binding bin= new Binding { Converter = new MethodConverter(MethodName,CanExecute) }; return bin.ProvideValue(serviceProvider); } } public class MethodConverter : IValueConverter { string MethodName; public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { //Convert to ICommand ICommand cmd = ConvertToICommand(); if (cmd == null) Debug.WriteLine(string.Format("Could not bind to method 'MyMethod' on object",MethodName)); return cmd; } } It works great, except when the binding fails(e.g. you mistype). When you do this in xaml: {Binding MyPropertyName} you see in the output window whenever the binding fails. and it tells you the propertyName the Type name etc. The MethodConverter Class can tell you the name of the method that failed, but it can't tell you the source object type. Because the value will be null. I can't figure out how to store the source object type so for the following class public class MyClass { public void MyMethod() { } } and the following xaml: <Button Command={d:MethodCall MyMethod}>My Method</Button> It currently says: "Could not bind to method 'MyMethod' on object but I would like it to say: "Could not bind to method 'MyMethod' on object MyClass Any ideas?

  • How to select and crop an image in android?

    - by Guy
    Hey, I am currently working on a live wallpaper and I allow the user to select an image which will go behind my effects. Currently I have: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); i.putExtra("crop", "true"); startActivityForResult(i, 1); And slightly under that: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); Log.d("IMAGE SEL", "" + selectedImage); // TODO Do something with the select image URI SharedPreferences customSharedPreference = getSharedPreferences("imagePref", Activity.MODE_PRIVATE); SharedPreferences.Editor editor = customSharedPreference.edit(); Log.d("HO", "" + selectedImage); editor.putString("imagePref", getRealPathFromURI(selectedImage)); Log.d("IMAGE SEL", getRealPathFromURI(selectedImage)); editor.commit(); } } When my code is ran, Logcat tells me that selectedImage is null. If I comment out the i.putExtra("crop", "true"): Logcat does not give me the null pointer exception, and I am able to do what I want with the image. So, what is the problem here? Does any one have any idea how I can fix this? Thanks, for your time.

  • Java, LinkedList of Strings. Insert in alphabetical order

    - by user69514
    I have a simple linked list. The node contains a string (value) and an int (count). In the linkedlist when I insert I need to insert the new Node in alphabetical order. If there is a node with the same value in the list, then I simply increment the count of the node. I think I got my method really screwed up. public void addToList(Node node){ //check if list is empty, if so insert at head if(count == 0 ){ head = node; head.setNext(null); count++; } else{ Node temp = head; for(int i=0; i<count; i++){ //if value is greater, insert after if(node.getItem().getValue().compareTo(temp.getItem().getValue()) > 0){ node.setNext(temp.getNext()); temp.setNext(node); } //if value is equal just increment the counter else if(node.getItem().getValue().compareTo(temp.getItem().getValue()) == 0){ temp.getItem().setCount(temp.getItem().getCount() + 1); } //else insert before else{ node.setNext(temp); } } } }

  • Android Custom Dialog NullPointerException

    - by Kyle Hughes
    I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

  • iPhone app stopped building crash reports

    - by BankStrong
    My app formerly created useful crash logs. I synced my iPhone in the past and found crash logs in library/logs/CrashReporter About a month ago, my app stopped creating crash reports. When I first discovered this problem, I assumed it was due to memory corruption (a possibility in my app). I just created a new project and added a crash to it. // Implement viewDidLoad to do additional setup after loading the view, // typically from a nib. - (void)viewDidLoad { NSMutableArray *array = [[NSMutableArray alloc] init]; [array removeObjectAtIndex:-1]; [super viewDidLoad]; } This app does not create a crash report either. Ideas I've started to explore: My phone is corrupted (tried restoring - somehow I brought it to the state from a few months ago) My XCode is corrupt (tried reinstalling, but current download demands Snow Leopard - and I can't upgrade to Snow Leopard online). This seems possible - I may have messed with device support around a month ago (similar to http://stackoverflow.com/questions/1224867/does-iphone-os-3-0-1-ruin-your-development-phone ) The location for crash logs has somehow moved. Suggestions?

  • Trying to debug a 'Assertion failure in -[UIActionSheet showInView:]' error....

    - by dsobol
    I am working through "Beginning iPad Application Development" and am getting hung up in Chapter 3 where I have created a project that works with an Action Sheet. As it stands now, my application loads into the simulator just fine with no errors that I am aware of, but as it runs, it crashes with the following errors showing up in the debugger window: 2010-05-31 19:44:39.703 UsingViewsActionSheet[49538:207] * Assertion failure in -[UIActionSheet showInView:], /SourceCache/UIKit_Sim/UIKit-1145.66/UIAlert.m:7073 2010-05-31 19:44:39.705 UsingViewsActionSheet[49538:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: view != nil' I am sure that this is the block where the app breaks based upon my use of breakpoints. //Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:@"This is my Action Sheet!" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:@"Delete Message!" otherButtonTitles:@"Option 1", @"Option 2", @"Option 3", nil]; [action showInView:self.view]; // <-- This line seems to trigger the crash.... [action release]; [super viewDidLoad]; } Am I missing something obvious, or is there more to the problem than is shown here? I have looked at the abstract for showInView and cannot divine anything there yet. I appreciate any and all asssitance. Regards, Steve O'Sullivan

  • Qt 5.3 OpenGL - vertex buffer object drawing using the core profile

    - by user3700881
    Im using Qt 5.3 to create a QWindow to do some basic rendering stuff. The QWindow is declared like this: class OpenGLWindow : public QWindow, protected QOpenGLFunctions_3_3_Core { Q_OBJECT ... } It is initialized in the constructor: OpenGLWindow::OpenGLWindow(QWindow *parent) : QWindow(parent) { QSurfaceFormat format; format.setVersion(3,3); format.setProfile(QSurfaceFormat::CoreProfile); this->setSurfaceType(OpenGLSurface); this->setFormat(format); this->create(); _context = new QOpenGLContext; _context->setFormat(format); _context->create(); _context->makeCurrent(this); this->initializeOpenGLFunctions(); ... } And that's the rendering code: void OpenGLWindow::render() { if(!isExposed()) return; _context->makeCurrent(this); glClear(GL_COLOR_BUFFER_BIT); glUseProgram(_shaderProgram); glBindBuffer(GL_ARRAY_BUFFER, _positionBufferObject); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0); glDrawArrays(GL_TRIANGLES, 0, 3); glDisableVertexAttribArray(0); glUseProgram(0); _context->swapBuffers(this); } I am trying to draw a simple triangle using a vertex and fragment shader. The problem is that the triangle is not showing up when the core profile is set. Only when I set the OpenGL version to 2.0 or when I use the compatibility profile, it shows up. From my point of view that doesn't make any sense because I am not using fixed functionality at all. What am I missing?

  • asp.net does not Redirect when in frameset

    - by Snoop Dogg
    I have developed an application on asp.net. I uploaded it to my host. lets say http://myhost/app. My manager wrapped this address into an empty frameset on http://anotherhost/somename and sets the src of frame to http://myhost/ap. And so nobody can login. When the button is hit, it posts back (browser loads stuff, progress bar fills up and ends) but nothing happens. Does not redirect. (I have set IE to alwaysAllowCookies and it now does work, but other people still cannot) I think there is something that I have no clue about framesets and ASP.NET ps: I never use frames but could not convince my manager in doing so. He likes to develop in front page :) Whatz happening? Thx in advance protected void btnLogin_Click(object sender, ImageClickEventArgs e) { Member member = Logic.DoLogin(txtUsername.Text.Trim(), txtPassword.Text.Trim()); if (null == member) { lblError.Text = "Invalid Login !"; return; } CurrentMember = member; ///CurrentMember is an inherited property that accesses Session["member"] = member Response.Redirect("Default.aspx");

  • Snow Leopard & LSUIElement -> application not activating properly, window not "active" despite being

    - by Frank R.
    Hi, I'm running into a few problem with a background application that uses LSUIElement=1 to hide its dock item, menu bar and prevent it from appearing in the Command-Tab application switcher. It seems to be a Snow Leopard only problem. The application places an NSStatusItem in the menu bar and pops up a menu when clicked on. Selecting "Preferences..." should bring up an NSWindow with the preferences. The first thing that doesn't seem to work is that the Window does not get ordered in at the front, but appears behind all other application windows. I tried to fix this by calling [[NSApplication sharedApplication] activateIgnoringOtherApps: YES] but that didn't work. After a while I figured out that the menu is blocking the message to the run loop from being sent, so I wrote another method on the MainController and sent the message with a delay: [self performSelector:@selector(setFront:) withObject: [preferencesController window] afterDelay:1.0]; -(void)setFront: (id) theWindow { [[NSApplication sharedApplication]activateIgnoringOtherApps:YES]; [theWindow orderFrontRegardless]; [theWindow makeKeyWindow]; [[NSApplication sharedApplication] activateIgnoringOtherApps:YES]; } Note the send-every-possible-message-to-make-it-do-what-it-should-be-doing-approach. This works, kind-of, the window is brought to the front on top of all other windows from all apps, BUT most of the time it isn't active, meaning it's title bar is greyed out. Clicking on the title bar won't make the window active either. Clicking INSIDE of the window will make it active!? This all didn't seem to be a problem in Leopard; just calling activateIgnoringOtherApps and making the window key seemed to work just fine. In Snow Leopard there is a new API designed to replace LSUIElement that is supposed to emulate its behaviour: http://developer.apple.com/mac/library/releasenotes/cocoa/appkit.html I've played around with that, but it's SL-only and I haven't been able to get LSUIElement being set. Any help would be greatly appreciated!

  • How to effectively use WorkbookBeforeClose event correctly?

    - by Ahmad
    On a daily basis, a person needs to check that specific workbooks have been correctly updated with Bloomberg and Reuters market data ie. all data has pulled through and that the 'numbers look correct'. In the past, people were not checking the 'numbers' which led to inaccurate uploads to other systems etc. The idea is that 'something' needs to be developed to prevent the use from closing/saving the workbook unless he/she has checked that the updates are correct/accurate. The numbers look correct action is purely an intuitive exercise, thus will not be coded in any way. The simple solution was to prompt users prior to closing the specific workbook to verify that the data has been checked. Using VSTO SE for Excel 2007, an Add-in was created which hooks into the WorkbookBeforeClose event which is initialised in the add-in ThisAddIn_Startup private void wb_BeforeClose(Xl.Workbook wb, ref bool cancel) { //.... snip ... if (list.Contains(wb.Name)) { DailogResult result = MessageBox.Show("some message", "sometitle", MessageBoxButtons.YesNo); if (result != DialogResult.Yes) { cancel = true; // i think this prevents the whole application from closing } } } I have found the following ThisApplication.WorkbookBeforeSave vs ThisWorkbook.Application.WorkbookBeforeSave which recommends that one should use the ThisApplication.WorkbookBeforeClose event which I think is what I am doing since will span all files opened. The issue I have with the approach is that assuming that I have several files open, some of which are in my list, the event prevents Excel from closing all files sequentially. It now requires each file to be closed individually. Am I using the event correctly and is this effective & efficient use of the event? Should I use the Application level event or document level event? Is there a way to prevent the above behaviour? Any other suggestions are welcomed VS 2005 with VSTO SE

  • Efficiently Determine if EF 4 POCO Already in ObjectSet

    - by Eric J.
    I'm trying EF 4 with POCO's on a small project for the first time. In my Repository implementation, I want to provide a method AddOrUpdate that will add a passed-in POCO to the repository if it's new, else do nothing (as the updated POCO will be saved when SaveChanges is called). My first thought was to do this: public void AddOrUpdate(Poco p) { if (!Ctx.Pocos.Contains<Poco>(p)) { Ctx.Pocos.AddObject(p); } } However that results in a NotSupportedException as documented under Referencing Non-Scalar Variables Not Supported (bonus question: why would that not be supported?) Just removing the Contains part and always calling AddObject results in an InvalidStateException: An object with the same key already exists in the ObjectStateManager. The existing object is in the Unchanged state. An object can only be added to the ObjectStateManager again if it is in the added state. So clearly EF 4 knows somewhere that this is a duplicate based on the key. What's a clean, efficient way for the Repository to update Pocos for either a new or pre-existing object when AddOrUpdate is called so that the subsequent call to SaveChanges() will do the right thing? I did consider carrying an isNew flag on the object itself, but I'm trying to take persistence ignorance as far as practical.

  • How to determine if an item is the last one in a WPF ItemTemplate?

    - by Mike
    Hi everyone, I have some XAML <ItemsControl Name="mItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Mode=OneWay}" KeyUp="TextBox_KeyUp"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> that's bound to a simple ObservableCollection private ObservableCollection<string> mCollection = new ObservableCollection<string>(); public MainWindow() { InitializeComponent(); this.mCollection.Add("Test1"); this.mCollection.Add("Test2"); this.mItemsControl.ItemsSource = this.mCollection; } Upon hitting the enter key in the last TextBox, I want another TextBox to appear. I have code that does it, but there's a gap: private void TextBox_KeyUp(object sender, KeyEventArgs e) { if (e.Key != Key.Enter) { return; } TextBox textbox = (TextBox)sender; if (IsTextBoxTheLastOneInTheTemplate(textbox)) { this.mCollection.Add("A new textbox appears!"); } } The function IsTextBoxTheLastOneInTheTemplate() is something that I need, but can't figure out how to write. How would I go about writing it? I've considered using ItemsControl.ItemContainerGenerator, but can't put all the pieces together. Thanks! -Mike

  • What am I doing wrong with HttpResponse content and headers when downloading a file?

    - by Slauma
    I want to download a PDF file from a SQL Server database which is stored in a binary column. There is a LinkButton on an aspx page. The event handler of this button looks like this: protected void LinkButtonDownload(object sender, EventArgs e) { ... byte[] aByteArray; // Read binary data from database into this ByteArray // aByteArray has the size: 55406 byte Response.ClearHeaders(); Response.ClearContent(); Response.BufferOutput = true; Response.AddHeader("Content-Disposition", "attachment; filename=" + "12345.pdf"); Response.ContentType = "application/pdf"; using (BinaryWriter aWriter = new BinaryWriter(Response.OutputStream)) { aWriter.Write(aByteArray, 0, aByteArray.Length); } } A "File Open/Save dialog" is offered in my browser. When I store this file "12345.pdf" to disk, the file has a size of 71523 Byte. The additional 16kB at the end of the PDF file are the HTML code of my page (as I can see when I view the file in an editor). I am confused because I was believing that ClearContent and ClearHeaders would ensure that the page content is not sent together with the file content. What am I doing wrong here? Thanks for help!

  • Threading is slow and unpredictable?

    - by Jake
    I've created the basis of a ray tracer, here's my testing function for drawing the scene: public void Trace(int start, int jump, Sphere testSphere) { for (int x = start; x < scene.SceneWidth; x += jump) { for (int y = 0; y < scene.SceneHeight; y++) { Ray fired = Ray.FireThroughPixel(scene, x, y); if (testSphere.Intersects(fired)) sceneRenderer.SetPixel(x, y, Color.Red); else sceneRenderer.SetPixel(x, y, Color.Black); } } } SetPixel simply sets a value in a single dimensional array of colours. If I call the function normally by just directly calling it it runs at a constant 55fps. If I do: Thread t1 = new Thread(() => Trace(0, 1, testSphere)); t1.Start(); t1.Join(); It runs at a constant 50fps which is fine and understandable, but when I do: Thread t1 = new Thread(() => Trace(0, 2, testSphere)); Thread t2 = new Thread(() => Trace(1, 2, testSphere)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); It runs all over the place, rapidly moving between 30-40 fps and sometimes going out of that range up to 50 or down to 20, it's not constant at all. Why is it running slower than it would if I ran the whole thing on a single thread? I'm running on a quad core i5 2500k.

  • Java: volatile guarantees and out-of-order execution

    - by WizardOfOdds
    Note that this question is solely about the volatile keyword and the volatile guarantees: it is not about the synchronized keyword (so please don't answer "you must use synchronize" for I don't have any issue to solve: I simply want to understand the volatile guarantees (or lack of guarantees) regarding out-of-order execution). Say we have an object containing two volatile String references that are initialized to null by the constructor and that we have only one way to modify the two String: by calling setBoth(...) and that we can only set their references afterwards to non-null reference (only the constructor is allowed to set them to null). For example (it's just an example, there's no question yet): public class SO { private volatile String a; private volatile String b; public SO() { a = null; b = null; } public void setBoth( @NotNull final String one, @NotNull final String two ) { a = one; b = two; } public String getA() { return a; } public String getB() { return b; } } In setBoth(...), the line assigning the non-null parameter "a" appears before the line assigning the non-null parameter "b". Then if I do this (once again, there's no question, the question is coming next): if ( so.getB() != null ) { System.out.println( so.getA().length ); } Am I correct in my understanding that due to out-of-order execution I can get a NullPointerException? In other words: there's no guarantee that because I read a non-null "b" I'll read a non-null "a"? Because due to out-of-order (multi)processor and the way volatile works "b" could be assigned before "a"? volatile guarantees that reads subsequent to a write shall always see the last written value, but here there's an out-of-order "issue" right? (once again, the "issue" is made on purpose to try to understand the semantics of the volatile keyword and the Java Memory Model, not to solve a problem).

  • Windows Forms Event Log

    - by blu
    I am writing to the event log from my Windows Forms application running on Windows 7 and am getting this message in the event log: The description for Event ID X from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: Exception Details the message resource is present but the message is not found in the string/message table My logging code is: public void Log(Exception exc) { EventLog.WriteEntry( "Application", exc.ToString(), EventLogEntryType.Error, 100); } My logging on Windows Forms is usually to a DB, but in this case decided to use the event log. I usually use the event log in ASP.NET applications, but those are on XP Pro locally and Windows Server 2003 on the web boxes. Is this a Windows 7 thing or a Windows Forms thing, and what should I do to fix this? Thanks.

  • SharpPcap issue

    - by Eyla
    This is my first time to use SharpPcap library. I created new project with VC# 2008 and I added SharpPcap as a reference to my project. I post a sample code to get interface of my pc but I'm getting this error: Error 1 The type or namespace name 'PcapDeviceList' could not be found (are you missing a using directive or an assembly reference?) C:\Users\Ali\Documents\Visual Studio 2008\Projects\Pcap\Pcap\Form1.cs 28 13 Pcap please advice to solve this problem. here is my code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using SharpPcap; using SharpPcap.Packets; using SharpPcap.Protocols; using SharpPcap.Util; namespace Pcap { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { /* Retrieve the device list */ PcapDeviceList devices = SharpPcap.GetAllDevices(); /*If no device exists, print error */ if (devices.Count < 1) { Console.WriteLine("No device found on this machine"); return; } int i = 0; /* Scan the list printing every entry */ foreach (PcapDevice dev in devices) { /* Description */ label1.Text = "{0}) {1}" + i + dev.PcapDescription +"\n"+ /* Name */ "\tName:\t{0}" + dev.PcapName+"\n"+ /* IP Address */ "\tIP Address: \t\t{0}"+ dev.PcapIpAddress+"\n"+ /* Is Loopback */ "\tLoopback: \t\t{0}"+ dev.PcapLoopback; i++; } } } }

  • Why `A & a = a` is valid?

    - by psaghelyi
    #include <iostream> #include <assert.h> using namespace std; struct Base { Base() : m_member1(1) {} Base(const Base & other) { assert(this != &other); // this should trigger m_member1 = other.m_member1; } int m_member1; }; struct Derived { Derived(Base & base) : m_base(m_base) {} // m_base(base) Base & m_base; }; void main() { Base base; Derived derived(base); cout << derived.m_base.m_member1 << endl; // crashes here } The above example is a synthesized version of a mistyped constructor. I used reference at the class member Derived::m_base because I wanted to make sure that the member will be initialized as the constructor had called. One problem is that nor GCC nor MSVC gives me a warning at m_base(m_base). But the more serious for me is that the assert finds everything fine and the application crashes later (sometimes far away from the mistake). Question: Is there any way to indicate such mistakes?
