  • How to give FTP address in java?

    - by i2ijeya
    I have written the code which downloads the file from FTP server. Since I have my FTP server locally and I want to access like "ftp://localhost/alfresco". It was alfresco's FTP. I have the following Code public class FtpTransfer { public static final void main(String[] args) { FTPClient ftp = new FTPClient(); FileOutputStream br = null; try { ftp.connect("ftp://localhost/alfresco"); ftp.login("admin", "admin"); String file = "KPUB//Admin//TMM//Pickup//TMM_TO_ARTESIA_06152010220246.xml"; br = new FileOutputStream("file"); ftp.retrieveFile("/"+file, br); System.out.println("Downloaded..."); } catch(IOException exception) { System.out.println("Error : "+exception); } } } The following exception occurs. Error : java.net.UnknownHostException: ftp://localhost/alfresco Please let me know how should I give the FTP Host Address?

  • FindBugs and CheckForNull on classes vs. interfaces

    - by ndn
    Is there any way to let FindBugs check and warn me if a CheckForNull annotation is present on the implementation of a method in a class, but not on the declaration of the method in the interface? import javax.annotation.CheckForNull; interface Foo { public String getBar(); } class FooImpl implements Foo { @CheckForNull @Override public String getBar() { return null; } } public class FindBugsDemo { public static void main(String[] args) { Foo foo = new FooImpl(); System.out.println(foo.getBar().length()); } } I just discovered a bug in my application due to a missing null check that was not spotted by FindBugs because CheckForNull was only present on FooImpl, but not on Foo, and I don't want to spot all other locations of this problem manually.

  • How to save state of the app when app terminates?

    - by user164589
    Hi guys. I am trying to save the app state by encoding when the app terminates. I've found the solution related this issue. But I don't know how to use. I am really trying to make encoding and decoding like this: http://cocoaheads.byu.edu/wiki/nscoding in CustomObject.h @interface CustomObject : NSObject <NSCoding> { NSArray *someArray; } in CustomObject.m @implementation CustomObject // Other method implementations here - (void) encodeWithCoder:(NSCoder*)encoder { [encoder encodeObject:someArray forKey:@"someArray"]; } - (id) initWithCoder:(NSCoder*)decoder { if (self = [super init]) { someArray = [[decoder decodeObjectForKey:@"someArray"] retain]; } return self; } @end My object to save is another NSArray. Not "someArray" in CustomObject. We call it that "MySaveObject". I want to pass "MySaveObject" to "someArray" in CustomObject. Actually I don't know how to encode "MySaveObject" and to pass to "someArray" in CustomObject. Thanks in advance.

  • Bug in Programming Interviews Exposed?

    - by Sam
    Hi, I could not find an errata for the 2nd edition of this book. My question concerns the if-statement in the following piece of code. void removeHead (Node ** head) { Node * temp; if (!(*head)) { temp = (*head)->next; delete *head; *head = temp; } } So I understand that the point of the if-statement is to check if the Node is null. However by adding an additional "!" to the evaluation, wouldn't this negate the false value of null? Would it be correct to change it to something like: if (*head) { ... } Also if anyone knows where I can find an official errata for the 2nd edition that would be great. Thanks, Sam

  • Is it a good practice to pass struct object as parameter to a function in c++?

    - by tsubasa
    I tried an example live below: typedef struct point { int x; int y; } point; void cp(point p) { cout<<p.x<<endl; cout<<p.y<<endl; } int main() { point p1; p1.x=1; p1.y=2; cp(p1); } The result thats printed out is: 1 2 which is what I expected. My question is: Does parameter p get the full copy of object p1? If so, I wonder if this is a good practice? (I assumed when the struct gets big in size, this will create a lot of copy overhead).

  • How to open connection to local network path protected by password in smart way? (Whith C#)

    - by lfx
    Hi, I developing program witch have to write some data in file whom are stored in network computer witch are protected by password. Now I'm doing this way - open connection with cmd then write data. static bool ConnectToSrv() { String myUser = "domain.local\\user"; String myPass = "pwd"; String cmdString = "net use \\\\otherPC\\folder\\ /user:" + myUser + " " + myPass; try { ManagementClass processClass = new ManagementClass("Win32_Process"); object[] methodArgs = { cmdString, null, null, 0 }; object result = processClass.InvokeMethod("Create", methodArgs); return true; } catch (System.Exception error) { return false; } } public void writeDate(string data){ } I believe there must by better way. I mean the .NET way. Does anybody know how to do it? :) Thanks

  • C# Inherited member variables behaving undexpectedly

    - by Nilbert
    If I have a class like this: class A { public string fe = "A"; } And a class that inherits from it like so: class B : A { public string fe = "B"; } Visual C++ will tell me that B.fe hides A.fe so I should use the new keyword. So I change class B to look like: class B : A { public new string fe = "B"; } And then I have a function that takes an A (but, by virtue of inheritance, will also take a B) like this: class D { public static void blah(A anAObject) { Console.Writeline(A.fe); } } Even when I pass it an instance of a B object, which it will take without question, it will print "A"! Why is this, and how can I make it work how I want without setting the variable in the constructor?

  • typedef resolution rule

    - by kumar_m_kiran
    Hi All, Can you Please tell me the resolution rule involved in resolving the meaning of the variable in a typedef. Any link related to the same will be very useful. Example #typedef string* pstring; const pstring parr; Here confusion arises whether const'ness is for pointer or the content. Now based on what thumb rule do can we start resolving the above interpretation of the pstring?. Smilarly, If I have a very complex typedef'ed variable, like #typedef void (func*)()(int), I should be able to resolve it using the thumb rule. Thanks in advance for your suggestions

  • How to look up an NHibernate entity's table mapping from the type of the entity?

    - by snicker
    Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code? Example: The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere. How can I make the following test pass? private const string LegacyPonyTableName = "AAZF1203"; [Test] public void MakeSureThatThePonyEntityIsMappedToCorrectTable() { string ponyTable = GetNHibernateTableMappingFor(typeof(Pony)); Assert.AreEqual(LegacyPonyTableName, ponyTable); } In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

  • Modal View Does Not Appear in Center in Horizontal Orientation

    - by Sheehan Alam
    I have a UIPresentationFormSheet (contains a textview) that appears in the center of the screen when I am in vertical orientation. When I dismiss the modal view, it disappears fine. When I am in horizontal orientation my modal view does not appear in the center of the screen. I have to dismiss my keyboard for the modal view to appear in the center. [self presentModalViewController:composeTweetController animated:TRUE]; When I dismiss the modal view in horizontal orientation the app automatically switches to vertical orientation. -(void)dismissComposeTweetView{ [self dismissModalViewControllerAnimated:TRUE]; } I want the following to happen: Modal view should appear in the center in horizontal orientation Modal view should disappear without switching to vertical orientation

  • Repeating animations using the Stop Selector

    - by Tiago
    I'm trying to repeat an animation until a certain condition is met. Something like this: - (void) animateUpdate { if (inUpdate) { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(animateUpdate)]; button.transform = CGAffineTransformMakeRotation( M_PI ); [UIView commitAnimations]; } } This will run the first time, but it won't repeat. The selector will just be called until the application crashes. How should I do this? Thanks.

  • Java-Recursion: When does statements after a recursive method call executes

    When are statements after the method call itself going to execute? private void inorderHelper(TreeNode node) { if ( node==null ) return; inorderHelper(node.leftNode); System.out.printf("%d", node.data); inorderHelper(node.rigthNode); } All I can see is that the line of codes inorderHelper(node.leftNode) will continue to iterate until node == null and the method terminates immediately before node.data is printed. I think that I didn't get well recursion but all examples I can find doesn't have statements after the recursive call. All I want to know is when are statements like System.out.printf("%d",node.data) going to execute before the method return?

  • How to wait for thread to finish with .NET?

    I've never really used threading before in C# where I need to have two threads, as well as the main UI thread. Basically, I have the following. public void StartTheActions() { //Starting thread 1.... Thread t1 = new Thread(new ThreadStart(action1)); t1.Start(); //Now, I want for the main thread (which is calling StartTheActions() ) to wait for t1 to finish (I have created an event in action1() for this) and then start t2... //HOW DO I DO THIS? Thread t2 = new Thread(new ThreadStart(action2)); t2.Start(); } So, essentially, my question is how to have a thread wait for another one to finish. What is the best way to do this? Thanks!
