• setting up linked list Java

  - by erp

  I'm working on some basic linked list stuff, like insert, delete, go to the front or end of the list, and basically i understand the concept of all of that stuff once i have the list i guess but im having trouble setting up the list. I was wondering of you guys could tell me if im going in the right direction. (mostly just the setup) this is what i have so far: public class List { private int size; private List linkedList; List head; List cur; List next; /** * Creates an empty list. * @pre * @post */ public List(){ linkedList = new List(); this.head = null; cur = head; } /** * Delete the current element from this list. The element after the deleted element becomes the new current. * If that's not possible, then the element before the deleted element becomes the new current. * If that is also not possible, then you need to recognize what state the list is in and define current accordingly. * Nothing should be done if a delete is not possible. * @pre * @post */ public void delete(){ // delete size--; } /** * Get the value of the current element. If this is not possible, throw an IllegalArgumentException. * @pre the list is not empty * @post * @return value of the current element. */ public char get(){ return getItem(cur); } /** * Go to the last element of the list. If this is not possible, don't change the cursor. * @pre * @post */ public void goLast(){ while (cur.next != null){ cur = cur.next; } } /** * Advance the cursor to the next element. If this is not possible, don't change the cursor. * @pre * @post */ public void goNext(){ if(cur.next != null){ cur = cur.next;} //else do nothing } /** * Retreat the cursor to the previous element. If this is not possible, don't change the cursor. * @pre * @post */ public void goPrev(){ } /** * Go to top of the list. This is the position before the first element. * @pre * @post */ public void goTop(){ } /** * Go to first element of the list. If this is not possible, don't change the cursor. * @pre * @post */ public void goFirst(){ } /** * Insert the given parameter after the current element. The newly inserted element becomes the current element. * @pre * @post * @param newVal : value to insert after the current element. */ public void insert(char newVal){ cur.setItem(newVal); size++; } /** * Determines if this list is empty. Empty means this list has no elements. * @pre * @post * @return true if the list is empty. */ public boolean isEmpty(){ return head == null; } /** * Determines the size of the list. The size of the list is the number of elements in the list. * @pre * @post * @return size which is the number of elements in the list. */ public int size(){ return size; } public class Node { private char item; private Node next; public Node() { } public Node(char item) { this.item = item; } public Node(char item, Node next) { this.item = item; this.next = next; } public char getItem() { return this.item; } public void setItem(char item) { this.item = item; } public Node getNext() { return this.next; } public void setNext(Node next) { this.next = next; } } } I got the node class alright (well i think it works alright), but is it necessary to even have that class? or can i go about it without even using it (just curious). And for example on the method get() in the list class can i not call that getItem() method from the node class because it's getting an error even though i thought that was the whole point for the node class. bottom line i just wanna make sure im setting up the list right. Thanks for any help guys, im new to linked list's so bear with me!

• How to update a vector in method

  - by gurpinars

  I'm new to C++ and trying to understand vectors. My goal is to update a vector in method: #include <vector> #include <iostream> using namespace std; void test(vector<int>& array){ for(int i=0;i<10;i++){ array.push_back(i); } } int main(){ // some integer value vector<int> array(10); test(array); for(int i=0;i<array.size();++i) cout<<array.at(i)<<endl; cout<<"array size:"<<array.size()<<endl; return 0; } output: 0 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 6 7 8 9 array size:20 I haven't figure out why 10 zeros add vector at first?

• Paged UIScrollView with UIImageViews only showing first UIImageVIew

  - by Jonathan Brown

  I am working on a paged UIScrollView, but it only wants to show the first UIImageView within it. I add each UIImageView at an offset of the width of the scroll view, so that should create each page. When run, it says the scroll view is the right number of pages, but the images don't show. Any help would be much appreciated! int numSlides = NUM_TUTORIAL_SLIDES; NSString *fileName; UIImageView *slideImageView; CGRect slideFrame; for (int i = 1; i <= numSlides; i++) { slideFrame.origin.x = self.tutorialScrollView.frame.size.width * (i-1); slideFrame.origin.y = 0; slideFrame.size = self.tutorialScrollView.frame.size; slideImageView = [[UIImageView alloc] initWithFrame:slideFrame]; if([[AppManager sharedManager] is4inchScreen]) { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } else { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } slideImageView.image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:fileName ofType:nil]]; [self.tutorialScrollView addSubview:slideImageView]; [slideImageView release]; } self.tutorialScrollView.contentSize = CGSizeMake(self.tutorialScrollView.frame.size.width * numSlides, self.tutorialScrollView.frame.size.height); self.tutorialScrollView.delegate = self;

• Scalable images in Java

  - by CodeGuy

  I anticipate using some images in my Java application. These images will be drawn onto my JPanel using g.drawImage(). The JPanel is resizable and the images should scale as the JPanel increases/decreases in size Two questions: What image format is best for this type of desired scalable image? For instance, in this application, an image of size 100x100 may be scaled into an image of size 30x30 or 10x10 or 300x300. How can I write code to do this scaling?

• Zoom in Java Swing application

  - by Shirky

  Hi there, I am looking for ways to zoom in a Java Swing application. That means that I would like to resize all components in a given JPanel by a given factor as if I would take an screenshot of the UI and just applied an "Image scale" operation. The font size as well as the size of checkboxes, textboxes, cursors etc. has to be adjusted. It is possible to scale a component by applying transforms to a graphics object: protected Graphics getComponentGraphics(Graphics g) { Graphics2D g2d=(Graphics2D)g; g2d.scale(2, 2); return super.getComponentGraphics(g2d); } That works as long as you don't care about self-updating components. If you have a textbox in your application this approach ceases to work since the textbox updates itself every second to show the (blinking) cursor. And since it doesn't use the modified graphics object this time the component appears at the old location. Is there a possibility to change a components graphics object permanently? There is also a problem with the mouse click event handlers. The other possibility would be to resize all child components of the JPanel (setPreferredSize) to a new size. That doesn't work for checkboxes since the displayed picture of the checkbox doesn't change its size. I also thought of programming my own layout manager but I don't think that this will work since layout managers only change the position (and size) of objects but are not able to zoom into checkboxes (see previous paragraph). Or am I wrong with this hypothesis? Do you have any ideas how one could achieve a zoomable Swing GUI without programming custom components? I looked for rotatable user interfaces because the problem seems familiar but I also didn't find any satisfying solution to this problem. Thanks for your help, Chris

• Read from socket

  - by Alberto

  I need to read from an AF_UNIX socket to a buffer using the function read from C, but I don't know the buffer size. I think the best way is to read N bytes until the read returns 0 (no more writers in the socket). Is this correct? Is there a way to guess the size of the buffer being written on the socket? I was thinking that a socket is a special file. Opening the file in binary mode and getting the size would help me in knowing the correct size to give to the buffer? I'm a very new to C, so please keep that in mind.

• capture the last WM_SIZE

  - by Michael

  When I resize my window I want to tell another part of my program that my window has changed size. I read on MSDN that: WM SIZE Message The WM SIZE message is sent to a window after its size has changed. However, I receive the WM_SIZE even when dragging. I noticed that there is also a WM_SIZING message that is sent when my window is resizing. At the moment I do not see the difference between WM_SIZE and WM_SIZING. Is there some way I can capture the very last WM_SIZE message, as to not "spam" my program with resize messages?

• PHP GD issues with ImageCreateTrueColor and PNGs

  - by DrPheltRight

  I am resizing PNG images using the GD image library function ImageCopyResampled(). It all works fine, I can even keep alpha blending transparency with the use of ImageCreateTrueColor() rather than using ImageCreate() to create the resized image. The problem is, that if I use ImageCreateTrueColor() rather than ImageCreate() the file size of PNG files increases from something like 80kb to 150kb. If I use ImageCreate() the file size stays around the same size, but colors screw! So my question is, how can I retain alpha blending when resizing PNG images without increasing the file size? Oh and I am reducing the dimensions of the PNGs.

• Can I use a single pointer for my hash table in C?

  - by aks

  I want to implement a hash table in the following manner: struct list { char *string; struct list *next; }; struct hash_table { int size; /* the size of the table */ struct list **table; /* the table elements */ }; Instead of struct hash_table like above, can I use: struct hash_table { int size; /* the size of the table */ struct list *table; /* the table elements */ }; That is, can I just use a single pointer instead of a double pointer for the hash table elements? If yes, please explain the difference in the way the elements will be stored in the table?

  Hi! I want to upload a large file of size 10M max to my mysql database.

But i can not insert the file in database if it is more that 1M in size. i am using file_get_contents to read all file data and pass it to the insert query as a string to be inserted into a LONGBLOB field. But files with more than 1M size is not being added to database, though i can use print_r($_FILES) to examine that the file uploaded correctly. Any help will be appreciated and i will need it within next 6 hours.

• EXC_BAD_ACCESS when returning a CGRect in iPhone

  - by pabloruiz55

  I have a class which must return a CGRect from one of its methods: -(CGRect)myRect { CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height); return rect; } I get an exc_bad_access as soon as i try to access the mySprite ivar. Thing is if i call it, the instance variable mySprite is full of garbage. BUT if i change the function to return void, self.mySprite does contain the correct data. -(void)myRect { CGRect rect = CGRectMake(self.mySprite.position.x,self.mySprite.position.y,self.mySprite.textureRect.size.width, self.mySprite.textureRect.size.height); return rect; } that does not crash when accessing mySprite...

• Need help finding a unique value in array

  - by bardockyo

  My code is complete minus one little flaw. It searches the array and prints out which values are unique, however it always counts the first entry as unique even if it is followed by the same value. Can anyone look at my code and tell me which part is messing this up because it is driving me crazy. #include <stdio.h> #define size 7 int main(void) { int array1[size], target, answer, found, x, k, prev, count =1, i; printf("Please input %d integers: ", size); scanf("%d", &target); for(x = 0; x < size; x++) { scanf("%d", &array1[x]); } prev = array1[0]; for (i = 1; i < size; i++) { if (array1[i] == prev) { count++; } else { if (count < 2) printf("%d=%d\n", prev, count); prev = array1[i]; count = 1; } } if (count < 2) { printf("%d=%d\n", prev, count); } return 0; }

• How to split up input from System.in

  - by zzaw

  Alright so I'm working on something where I take input from System.in; the first line is an int (n) representing the size of a matrix. The next n lines are the matrix itself like so: 10 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 0 1 0 0 1 1 0 0 1 0 0 0 0 0 1 0 0 0 0 0 0 0 1 1 0 0 0 1 1 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 The problem is there may be multiple matrix's in a single input, so the next line would have another int and the corresponding matrix underneath until it hits a line with a single 0. I then have to pass each matrix along with the size at the top as a BufferedReader to a method which adds the numbers to a 2D array. I'm just a little unsure on how to split the input up and send it to the method. Would making a new BufferedReader using skip() and specifying a size each time work? The biggest problem I seem to be running into is reading the size but then the size being excluded as it has already been read. Cheers

• Should i keep #wrapper{ width:100%} in print css?

  - by metal-gear-solid

  Should i keep #wrapper{ width:100%} in print css? because on screen my design is a fixed width design 960 px. but there are so many paper type and sizes in the world and anybody can take print on any size paper, bigger and smaller. So if in print css i do not specify relative width then i think print of page will cut of from right size if user will take print on the paper size which can smaller or larger width than my site #wrapper width (960px). then it can create problem. http://www.dpandi.com/paper/index.html printer also leave some margin when printing. So should keep everything is relative size in print css?

I've tried connecting through both USB and Bluetooth tethering to the iPhone, and they both return the exact same results. I don't have direct control over the firewall, but if changes are necessary to make it work, I may be able to get the powers-that-be to make adjustments. A solution that doesn't require reconfiguring the firewall would be far better of course... Does anyone know what I can do to make this behave? Thanks, Dan

• Can't sync filesystem without reboot

  - by Fabio

  I'm having an issue with a linux server. Once a week the running mysql instance hangs and there is no way to fully stop it. If I kill it, it remains in zombie status and init does not reap its pid. The server is used for staging deployments and some internal tools, so it's not under heavy load. The only process constantly used id mysql and for this I think that it's the only process which suffer of this issue. I've searched system logs for errors and the only thing I found is this error (repeated a couple of times) in dmesg output: [706560.640085] INFO: task mysqld:31965 blocked for more than 120 seconds.

• Raid 1 array won't assemble after power outage. How do I fix this ext4 mirror?

  - by Forkrul Assail

  Two ext4 drives on Raid 1 with mdadm won't reassemble after the power went out for an extended period (UPS drained). After turning the machine back on, mdadm said that the array was degraded, after which it took about 2 days for a full resync, which completed without problems. On trying to remount the array I get: mount: you must specify the filesystem type cat /etc/fstab lines relevant to setup: /dev/md127 /media/mediapool ext4 defaults 0 0 dmesg | tail (on trying to mount) says: [ 1050.818782] EXT3-fs (md127): error: can't find ext3 filesystem on dev md127.

Could someone explain why it would resync after the powerout, only to seemingly nuke the drive? Thanks for reading. Any help much appreciated. I've tried everything I can think of, including booting and filesystem checking with SystemRescue and Ubuntu liveboot discs.

• "Can't create table" when having to many partitions

  - by Chris

  I am currently having a problem I dont understand. Wherever I look it says mySQL (5.5) / InnoDB doesnt have a table limit.

• MailEnable - Configuring TLS for secure SMTP (Gmail)

  - by Buckers

  I have the latest version of MailEnable Pro installed on a new server that I'm setting up. Sending & receiving works fine with a new email account that I have set up, however I am now trying to configure GMail to use the mailserver for outgoing SMTP. I've done the following so far: Creating a self-cert SSL certficiate Ticked "Enable TLS" on the General tab of the SMTP connector properties Ticked "Send using TLS if remote server supports it" on the Outbound tab of the SMTP connector properties Selected the new self-cert SSL certificate on the SSL tab of the localhost server properties. Given permissions to IME_System on the new certificate However, Gmail is still giving me the following error: Authentication failed. Please check your username/password. [Server response: 454 TLS not available due to temporary reason code(454) ] I'm trying to connect on port 25, (someone told me you can still do this and you dont have to connect on 465). Is this right? Or do I need to tell MailEnable to use port 465? Am I missing something? Thanks, Chris.

• WMI permissions: Select CommandLine, ProcessId FROM Win32_Process returns no data for CommandLine

  - by user57935

  Hi all, I am gathering performance data via WMI and would like to avoid having to use an account in the Administrators group for this purpose. The target machine is running Windows Server 2003 with the latest SP/updates. I've done what I believe to be the appropriate configuration to allow our user access to WMI (similar to what is described here: http://msdn.microsoft.com/en-us/library/aa393266.aspx). Here are the specific steps that were followed: Open Administrative Tools - Computer Management: Under Computer Management (Local) Expand Services and Applications, right click WMI Control and select properties. In the Security tab, expand Root, highlight CIMV2, click Security (near bottom of window); add Performance Monitor Users and enable the options : Enable Account and Remote Enable. ­Open Administrative Tools - Component Services: Under Console Root go to Component Services- Computers - Right click My Computer and select properties, select the COM security tab, in “Access Permissions” click "Edit Default" select(or add then select) “Performance Monitor Users” group and allow local access and remote access and click ok. In “Launch and Activation Permissions” click “Edit Default” select(or add then select) “Performance Monitor Users” group and allow Local and Remote Launch and Activation Permissions. ­Open Administrative Tools - Component Services: Under Console Root go to Component Services- Computers - My Computer - DCOM Config - highlight “Windows Management and Instrumentation” right click and select properties, Select the Security tab, Under “Launch and Activation Permissions” select Customize, then click edit, add the “Performance Users Group” and allow local and remote Remote Launch and Remote Activation privileges. I am able to connect remotely via WMI Explorer but when I perform this query: Select CommandLine, ProcessId FROM Win32_Process I get a valid result but every row has an empty CommandLine. If I add the user to the Administrators group and re-run the query, the CommandLine column contains the expected data. It seems there is a permission I am missing somewhere but I am not having much luck tracking it down. Many thanks in advance.
