  • Compression Program in C

    - by Delandilon
    I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

  • Is there any well-known paradigm for iterating enum values?

    - by SadSido
    I have some C++ code, in which the following enum is declared: enum Some { Some_Alpha = 0, Some_Beta, Some_Gamma, Some_Total }; int array[Some_Total]; The values of Alpha, Beta and Gamma are sequential, and I gladly use the following cycle to iterate through them: for ( int someNo = (int)Some_Alpha; someNo < (int)Some_Total; ++someNo ) {} This cycle is ok, until I decide to change the order of the declarations in the enum, say, making Beta the first value and Alpha - the second one. That invalidates the cycle header, because now I have to iterate from Beta to Total. So, what are the best practices of iterating through enum? I want to iterate through all the values without changing the cycle headers every time. I can think of one solution: enum Some { Some_Start = -1, Some_Alpha, ... Some_Total }; int array[Some_Total]; and iterate from (Start + 1) to Total, but it seems ugly and I have never seen someone doing it in the code. Is there any well-known paradigm for iterating through the enum, or I just have to fix the order of the enum values? (let's pretend, I really have some awesome reasons for changing the order of the enum values)...

  • getline with ints C++

    - by Mdjon26
    I have a file 0 3 2 1 2 3 4 5 6 6 8 1 Where the first number for each line is the row, the second number is the column, and the third number is the data contained in that row, column. This will be a given [8][8] array so I have already initialized everything to 0, but how can I store each of these data values? For example, I want [0][3] =2 and [1][2] = 3. I would like to keep track of the line on which I found that row, col, and data value. So, how can I correctly insert these values into my 2-D array? int rowcol[8][8]; for (int i=0; i < 9; i++) for (int j=0; j < 9; j++) { rowcol[i][j] =0; } ifstream myfile; int nums; myfile.open(text.c_str()); while (!myfile.eof()) { myfile >> nums; numbers.push_back(nums); } for (int i=0; i < numbers.size(); i++) { //Not sure what the best approach here would be and I'm not even sure if I should have done a vector... }

  • JQUERY - how to get updated value after ajax removes data from within it?

    - by Brian
    I have a an element with thumbnails. I allow users to sort their display order (which fires off an update to the DB via ajax). I also allow them to delete images (which, after deletion, fires off a request to update the display order for all remaining images). My problem is with binding or live I think, but I don't know where to apply it. The array fired off upon delete contains ALL the ids for the images that were there on page load. The issue is that after they delete an image the array STILL contains the original ids (including the one that was deleted) so it is obviously not refreshing the value of the element after ajax has removed things from inside it. I need to tell it to go get the refreshed contents... From what I have been reading, this is normal but I don't understand how to tie it into my routine. I need to trigger the mass re-ordering after any deletion. Any ideas gurus? $('a.delimg').click(function(){ var parent = $(this).parent().parent(); var id = $(this).attr('id'); $.ajax({ type: "POST", url: "../updateImages.php", data: "action=delete&id=" + id, beforeSend: function() { parent.animate({'backgroundColor':'#fb6c6c'},300); $.jnotify("<strong>Deleting This Image & Updating The Image Order</strong>", 5000); }, success: function(data) { parent.slideUp(300,function() { parent.remove(); $("#images ul").sortable(function() { //NEEDS TO GET THE UPDATED CONTENT var order = $(this).sortable("serialize") + '&action=updateRecordsListings'; $.post("../updateImages.php", order, function(theResponse){ $.jnotify("<strong>" + theResponse + "</strong>", 2000); }); }); }); } }); return false; }); Thanks for any help you can be.

  • creating a vector with references to some of the elements of another vector

    - by memC
    hi, I have stored instances of class A in a std:vector, vec_A as vec_A.push_back(A(i)). The code is shown below. Now, I want to store references some of the instances of class A (in vec_A) in another vector or another array. For example, if the A.getNumber() returns 4, 7, 2 , I want to put a reference to that instance of A in another vector, say std:vector<A*> filtered_A or an array. Can someone sow me how to do this?? Thanks! class A { public: int getNumber(); A(int val); ~A(){}; private: int num; }; A::A(int val){ num = val; }; int A::getNumber(){ return num; }; int main(){ int i =0; int num; std::vector<A> vec_A; for ( i = 0; i < 10; i++){ vec_A.push_back(A(i)); } std::cout << "\nPress RETURN to continue..."; std::cin.get(); return 0; }

  • retrieve only sub-pages (wordpress)

    - by Radek
    I want to list all sub-pages only one level though of one particular page. I was reading Function Reference/get pages and thought that $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; will do the trick but it is not working. It lists all pages on the same level like the page I call that code from. If I omit parent option I will get all pages even with sub-pages that I want. But I want only sub-pages. The whole function is like function about_menu(){ if (is_page('about')){ $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; foreach($pages as $page) { ?> <h2><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h2> <?php } } } and mine is second one

  • UITableView populating EVERY OTHER launch

    - by Joshmattvander
    I am having a problem that I cant seem to get to the bottom of. In my view did load code, I am creating an array and attempting to populate the table. For some reason it only populates the data on EVERY OTHER time the app is run. I put logs in viewDidLoad which runs as does viewWillAppear and outputs the correct count for the array. Also, the UITableView specicic methods get called when it works and they just don't get called when it doesnt work. I cant figure out the root of this problem. Again this occurrence happens exactly 50% of the time. Theres no dynamic data that could be tripping up or anything. #import "InfoViewController.h" @implementation InfoViewController - (void)viewDidLoad { NSLog(@"Info View Loaded"); // This runs infoList = [[NSMutableArray alloc] init]; //Set The Data //Theres 8 similar lines [infoList addObject :[[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Scrubbed", @"name", @"scrubbed", @"url", nil]]; NSLog(@"%d", [infoList count]); // This shows the count correctly every time [super viewDidLoad]; } -(void) viewWillAppear:(BOOL)animated { NSLog(@"Info Will Appear"); // This Runs } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // This WILL NOT RUN when it doesnt work, and DOES show the count when it does run NSLog(@"Counted in numberOfRowsInSection %d", [infoList count]); return [infoList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"ROW"); static NSString *CellIdentifier = @"infoCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.textLabel.text = [[infoList objectAtIndex:indexPath.row] objectForKey:@"name"]; return cell; } @end

This is how I'm setting the array: NSMutableArray *notesArray = [[NSMutableArray alloc] init]; [notesArray addObject:@"-"]; [notesArray addObjectsFromArray:[dbManager getTableValues:@"Notes"]]; self.notes = notesArray; [notesArray release]; The info for the pickerView is taken from the database in this method: -(NSMutableArray *)getTableValues:(NSString *)table { NSMutableArray *valuesArray = [[NSMutableArray alloc] init]; if (sqlite3_open([self.databasePath UTF8String], &database) != SQLITE_OK) { sqlite3_close(database); NSAssert(0, @"Failed to open database"); } else { NSString *query = [[NSString alloc] initWithFormat:@"SELECT value FROM %@", table]; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { NSString *value =[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]; [valuesArray addObject:value]; [value release]; } sqlite3_reset(statement); } [query release]; sqlite3_finalize(statement); sqlite3_close(database); } return valuesArray; } But I keep getting memory leaks in Instruments for these lines: NSMutableArray *valuesArray = [[NSMutableArray alloc] init]; and [valuesArray addObject:value]; What am I doing wrong here?

  • Zend Metadata Cache in file

    - by Matthieu
    I set up a metadata cache in Zend Framework because a lot of DESCRIBE queries were executed and it affected the performances. $frontendOptions = array ('automatic_serialization' => true); $backendOptions = array ('cache_dir' => CACHE_PATH . '/db-tables-metadata'); $cache = Zend_Cache::factory( 'Core', 'File', $frontendOptions, $backendOptions ); Zend_Db_Table::setDefaultMetadataCache($cache); I can indeed see the cache files created, and the website works great. However, when I launch unit tests, or a script of the same application that perform DB queries, I end up with an error because Zend couldn't read the cache files. This is because in the website, the cache files are created by the www user, and when I run phpunit or a script, it tries to read them with my user and it fails. Do you see any solution to that? I have some quickfix ideas but I'm looking for a good/stable solution. And I'd rather avoid running phpunit or the scripts as www if possible (for practical reasons).

    My iPhone app has the following problem: Freshly installed, when I read out my "Play Sound" preference with the following code: defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"Play Sounds? %d", [defaults boolForKey:@"play_sounds_preference"]); The setting always reads out as false, even though the default setting is set to true.

  • C# xml serializer - serialize derived objects

    - by gln
    Hi, I want to serialize the following: [Serializable] [DefaultPropertyAttribute("Name")] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfo { private string name; [XmlArray("Items"), XmlArrayItem(typeof(ItemInfo))] private ArrayList arr; private ItemInfo parentItemInfo; } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoA : ItemInfo { ... } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoB : ItemInfo { ... } The class itemInfo describes a container which can hold other itemInfo objects in the array list, the parentItemInfo describes which is the parent container of the item info. Since ItemInfoA and ItemInfoB derive from ItemInfo they can also be a member of the array list and the parentItemInfo, therefore when trying to serialize these objects (which can hold many objects in hierarchy) it fails with exception can't generate the xml file - innerexception. My question is: What attributes do I need to add the ItemInfo class so it will be serializable? Note: the exception is only when the ItemInfo[A]/[B] are initialized with parentItemInfo or the arrayList. Help please! Thanks!

  • Determining difference in timestamps for two values in the same MySQL table

    - by JayRizzo03
    I am relatively new to programming in PHP, so I apologize if this is a rather simple question. I have a MySQL database table called MachineReports that contains the following values: ReportNum(primary key, auto increment), MachineID and Timestamp Here is some example data: |ReportNum | MachineID | Timestamp | |1 | AD3203 | 2012-11-18 06:32:28| |2 | AD3203 | 2012-11-19 04:00:15| |3 | BC4300 | 2012-11-19 04:00:15| What I am attempting to do is find the difference in timestamps in seconds for each machine ID by iterating over each row set. I am getting stuck on the best way to do this, however. Here is the code I've written so far: <?php include '../dbconnect/dbconnect.php'; $machineID=[]; //Get a list of all MachineIDs in the database foreach($dbh->query('SELECT DISTINCT(MachineID) FROM MachineReports') as $row) { array_push($machineID, $row[0]); } for($i=0;$i<count($machineID);$i++){ foreach($dbh->query("SELECT MachineID FROM MachineReports WHERE MachineID='$machineID[$i]' ORDER BY MachineID") as $row) { //code to associate each machineID with two time stamps goes here } } ? This code just lists out the contents of the table row by row. My ultimate goal is to find the difference in timestamps for a certain MachineID. One of the things I've considered is using a multidimensional array in php - using the $machineID as the key and then storing the timestamp inside the array the key points to. However, I'm uncertain how to do that since my query parses row by row. I have quite a few questions. 1) Is this the most efficient way to be doing this? I suspect my database table design may not be the best. 2)What would be the best way to determine the difference in timestamps for a certain machineID? Even just a pointer to a topic that would prompt me to think about this in a different way would be helpful - I'm not afraid to do research. Thanks!

  • Javascript BBcode function not working

    I have a string I want to convert to divs but it doesn't close the div properly. The example string i am using is this: [quote]Quote by: user1 [quote]Quote by: user2 ads[/quote]Test[/quote]Testing 2. This results in: <div class="quote" style="margin-left:10px;margin-top:10px;"> Quote by: user1 [quote]Quote by: user2 ads </div> Test[/quote]Testing 2. But it will not convert the internal quotes properly. My Javascript function is like this: function bbcode_parser(str) { search = new Array( /\[b\](.*?)\[\/b\]/g, /\[i\](.*?)\[\/i\]/g, /\[quote](.*?)\[\/quote\]/g, /\[\*\]\s?(.*?)\n/g); replace = new Array( "<strong>$1</strong>", "<em>$1</em>", "<div class='quote' style='margin-left:10px;margin-top:10px;'>$1</div>"); for (i = 0; i < search.length; i++) { str = str.replace(search[i], replace[i]); } return str; } I have provided a JSFiddle for you to see it in action: http://jsfiddle.net/gRaFW/2/ Please help :)

  • Is there an Easier way to Get a 3 deep Panel Control from a Form in order to add a new Control to it programmatically?

    - by Mark Sweetman
    I have a VB Windows Program Created by someone else, it was programmed so that anyone could Add to the functionality of the program through the use of Class Libraries, the Program calls them (ie... the Class Libraries, DLL files) Plugins, The Plugin I am creating is a C# Class Library. ie.. .dll This specific Plugin Im working on Adds a Simple DateTime Clock Function in the form of a Label and inserts it into a Panel that is 3 Deep. The Code I have I have tested and it works. My Question is this: Is there a better way to do it? for instance I use Controls.Find 3 different times, each time I know what Panel I am looking for and there will only be a single Panel added to the Control[] array. So again Im doing a foreach on an array that only holds a single element 3 different times. Now like I said the code works and does as I expected it to. It just seems overly redudant, and Im wondering if there could be a performance issue. here is the code: foreach (Control p0 in mDesigner.Controls) if (p0.Name == "Panel1") { Control panel1 = (Control)p0; Control[] controls = panel1.Controls.Find("Panel2", true); foreach (Control p1 in controls) if (p1.Name == "Panel2") { Control panel2 = (Control)p1; Control[] controls1 = panel2.Controls.Find("Panel3", true); foreach(Control p2 in controls1) if (p2.Name == "Panel3") { Control panel3 = (Control)p2; panel3.Controls.Add(clock); } } }

  • Yii 'limit' on related model's scope

    - by pethee
    I have a model called Guesses that has_many Comments. I'm making eager queries to this to then pass on as JSON as response to an API call. The relations are obviously set between the two models and they are correct(one2many <= belongs2) I added a scope to Comments called 'api' like this: public function scopes() { return array( 'api' => array( 'select' => 'id, comment, date', 'limit'=>3, 'order'=>'date DESC', 'together'=>true, ), ); } And I'm running the following one-liner query: $data = Guesses::model()->with('comments:api')->findAll(); The issue here is that when calling the 'api' scope using a with('relation'), the limit property simply doesn't apply. I added the 'together'=true there for another type of scope, plus I hear it might help. It doesn't make a difference. I don't need all the comments of all Guesses. I want the top 3 (or 5). I am also trying to keep the one-liner call intact and simple, manage everything through scopes, relations and parameterized functions so that the API call itself is clean and simple. Any advice?

  • lightbox dynamic image retrieval

    - by GSTAR
    I am constructing a lighbox gallery, currently experimenting with FancyBox (http://fancybox.net) and ColorBox (http://colorpowered.com/colorbox). By default you have to include a link to the large version of the image so that the Lightbox can display it. However, I am wanting to have the image link URLs pointing to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg"> I want to do: <a href="mysite/photos/view/abc123"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $user=$photo->user; $this->renderPartial('_photo', array('user'=>$user, 'photo'=>$photo, true)); } } At some point in the future the function will also update the view count of the image. Now this approach is working to an extent - most images load up but some do not load up (the lightbox gets displayed in a malformed state). I think the reason for this is because it is not processing the function quick enough. For example when I click the "next" button it needs to go to the URL, process the function and retreive/output the response. Does anybody know how I can get this working properly?

But when I try to output $link_images it contains everything inside the first index: <pre> <?php print_r($link_images); ?> </pre> The markup looks something like this: Array ( [0] = Array ([0] = " <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p> But when outputting the contents of the matches, it simply returns the first string that matches the pattern plus all the other markup in the page like this: <a href="{$image_url}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url}" width="568" height="347"></a></p> <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p>")

  • Can someone answer this for me?

    - by Dcurvez
    okay I am totally stuck. I have been getting some help off and on throughout this project and am anxious to get this problem solved so I can continue on with the rest of this project. I have a gridview that is set to save to a file, and has the option to import into excel. I keep getting an error of this: Invalid cast exception was unhandled. At least one element in the source array could not be cast down to the destination array type. Can anyone tell me in layman easy to understand what this error is speaking of? This is the code I am trying to use: Dim fileName As String = "" Dim dlgSave As New SaveFileDialog dlgSave.Filter = "Text files (*.txt)|*.txt|CSV Files (*.csv)|*.csv" dlgSave.AddExtension = True dlgSave.DefaultExt = "txt" If dlgSave.ShowDialog = Windows.Forms.DialogResult.OK Then fileName = dlgSave.FileName SaveToFile(fileName) End If End Sub Private Sub SaveToFile(ByVal fileName As String) If DataGridView1.RowCount > 0 AndAlso DataGridView1.Rows(0).Cells(0) IsNot Nothing Then Dim stream As New System.IO.FileStream(fileName, IO.FileMode.Append, IO.FileAccess.Write) Dim sw As New System.IO.StreamWriter(stream) For Each row As DataGridViewRow In DataGridView1.Rows Dim arrLine(9) As String Dim line As String **row.Cells.CopyTo(arrLine, 0)** line = arrLine(0) line &= ";" & arrLine(1) line &= ";" & arrLine(2) line &= ";" & arrLine(3) line &= ";" & arrLine(4) line &= ";" & arrLine(5) line &= ";" & arrLine(6) line &= ";" & arrLine(7) line &= ";" & arrLine(8) sw.WriteLine(line) Next sw.Flush() sw.Close() End If I bolded the line where it shows in debug, and I really dont see what all the fuss is about LOL

  • how to pass vector of string to foo(char const *const *const)?

    - by user347208
    Hi, This is my first post so please be nice. I searched in this forum and googled but I still can not find the answer. This problem has bothered me for more than a day, so please give me some help. Thank you. I need to pass a vector of string to a library function foo(char const *const *const). I can not pass the &Vec[0] since it's a pointer to a string. Therefore, I have an array and pass the c_str() to that array. The following is my code (aNames is the vector of string): const char* aR[aNames.size()]; std::transform(aNames.begin(), aNames.end(), aR, boost::bind(&std::string::c_str, _1)); foo(aR); However, it seems it causes some undefined behavior: If I run the above code, then the function foo throw some warnings about illegal characters ('èI' blablabla) in aR. If I print aR before function foo like this: std::copy(aR, aR+rowNames.size(), std::ostream_iterator<const char*>(std::cout, "\n")); foo(aR); Then, everything is fine. My questions are: Does the conversion causes undefined behavior? If so, why? What is the correct way to pass vector of string to foo(char const *const *const)? Thank you very much for your help!

  • C code Error: free(): invalid next size (fast):

    - by user1436057
    I got an error from my code, but I'm not sure where to fix it. Here's the explanation of what my code does: I'm writing some code that will read an input file and store each line as an object (char type) in an array. The first line of the input file is a number. This number tells me how many lines that I should read and store in the array. Here's my code: int main(int argc, char *argv[]){ FILE *fp; char **path; int num, i; ... /*after reading the first line and store the number value in num*/ path = malloc(num *sizeof(char)); i=0; while (!feof(fp)) { char buffer[500]; int length = 0; for (ch = fgetc(fp); ch != EOF && ch != '\n'; ch = fgetc(fp)) { buffer[length++] = ch; } if(ch == '\n' && ch!= EOF){ buffer[length] = '\0'; path[i] = malloc(strlen(buffer)+1); strcpy(path[i], buffer); i++; } } ... free(path); } After running the code, I get this *** glibc detected *** free(): invalid next size (fast): I have searched around and know this is malloc/free error, but I don't exactly know to fix it. Any help would be great. Thanks!

  • HTML5 card game [closed]

    - by ChrisCa
    I created a card game in silverlight a year or so ago in order to learn a bit about Silverlight. I am now wanting to make a HTML5 version of the game in an effort to learn a little bit more about that. I am thinking I'd like to take advantage of stuff like Knockout.js and WebSockets and the canvas element. Now what I'm confused about is how to lay out the cards on the screen. With Silverlight I was able to make a "Hand" control, which was made up of two sub controls - the cards the player has in their hand and the ones they have on the table. And they in turn were made up of Card controls. Now I don't believe there is the concept on a User Control in javascript. So I am possibly thinking about this in entirely the wrong way. So my question is - how could I lay out some cards on the table and perhaps make reuse of something for each player? I have a client side JSON object called game, which contains an array of players. Each player has a hand which is made up of an array of in-hand cards and on-table cards. Ideally I would like to bind these to something using Knockout.js - but I don't know what I could bind to. Would I simply position images (of cards) on a canvas? Is there a way to make some kind of Hand object that each player could have and that I could bind to? Any advice? Or sample code you've seen elsewhere?
