  • Python: Copying files with special characters in path

    - by erikderwikinger
    Hi is there any possibility in Python 2.5 to copy files having special chars (Japanese chars, cyrillic letters) in their path? shutil.copy cannot handle this. here is some example code: import copy, os,shutil,sys fname=os.getenv("USERPROFILE")+"\\Desktop\\testfile.txt" print fname print "type of fname: "+str(type(fname)) fname0 = unicode(fname,'mbcs') print fname0 print "type of fname0: "+str(type(fname0)) fname1 = unicodedata.normalize('NFKD', fname0).encode('cp1251','replace') print fname1 print "type of fname1: "+str(type(fname1)) fname2 = unicode(fname,'mbcs').encode(sys.stdout.encoding) print fname2 print "type of fname2: "+str(type(fname2)) shutil.copy(fname2,'C:\\') the output on a Russian Windows XP C:\Documents and Settings\+????????????\Desktop\testfile.txt type of fname: <type 'str'> C:\Documents and Settings\?????????????\Desktop\testfile.txt type of fname0: <type 'unicode'> C:\Documents and Settings\+????????????\Desktop\testfile.txt type of fname1: <type 'str'> C:\Documents and Settings\?????????????\Desktop\testfile.txt type of fname2: <type 'str'> Traceback (most recent call last): File "C:\Test\getuserdir.py", line 23, in <module> shutil.copy(fname2,'C:\\') File "C:\Python25\lib\shutil.py", line 80, in copy copyfile(src, dst) File "C:\Python25\lib\shutil.py", line 46, in copyfile fsrc = open(src, 'rb') IOError: [Errno 2] No such file or directory: 'C:\\Documents and Settings\\\x80\ xa4\xac\xa8\xad\xa8\xe1\xe2\xe0\xa0\xe2\xae\xe0\\Desktop\\testfile.txt'

  • I have a problem with mysql and php

    - by neo skosana
    Hi I have a problem, this is my code: $db = new mysqli("localhost", "root", "", "blah"); $result1 = $db-query("select * from c_register where email = '$eml' and password = '$pass'"); if($result1-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'client'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result2 = $db-query("select * from b_register where email = '$eml' and password = '$pass'"); if($result2-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'business'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result3 = $db-query("select * from g_register where email = '$eml' and password = '$pass'"); if($result3-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'employee'; promptUser("You have successfully logged in!!!","index.php"); } $db = new mysqli("localhost", "root", "", "blah"); $result4 = $db-query("select * from k_register where email = '$eml' and password = '$pass'"); if($result4-fetch_array()) { $auth->createSession(); $_SESSION['user'] = 'super'; promptUser("You have successfully logged in!!!","index.php"); } else { promptUser("Username/Password do not match.

  • Why doesn't setting clearTaskOnLaunch="true" cause OnCreate to be called?

    - by cbrauer
    My application works fine, once it is initialized in the OnCreate method of my View class. However, when I open my app after the Droid phone has been sitting idle all night, the OnCreate method is not being called. I use the OnCreate to initialize data, and that in turn initializes the GUI. The GUI clearly shows that OnCreate was not called. I tried setting clearTaskOnLaunch="true" in my Manifest. My Manifest is: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.hedgetools.trin" android:versionCode="2" android:versionName="1.02"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:clearTaskOnLaunch="true"> <activity android:name=".Trin" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="6" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> </manifest> This did not help. My OnCreate method is not being call after the Droid phone sits idle all night. Why doesn’t clearTaskOnLaunch cause OnCreate to be called? Any help or suggestions will be greatly appreciated.

  • AJAX Post Not Sending Data?

    - by Jascha
    I can't for the life of me figure out why this is happening. This is kind of a repost, so forgive me, but I have new data. I am running a javascript log out function called logOut() that has make a jQuery ajax call to a php script... function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/functions.php', data: data, success: function() { alert('done'); } }); } the php function it calls is here: if(isset($_POST['log_out'])){ $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('logOutSuccess')"; $connection->runQuery($query); // <-- my own database class... // omitted code that clears session etc... die(); } Now, 18 hours out of the day this works, but for some reason, every once in a while, the POST data will not trigger my query. (this will last about an hour or so). I figured out the post data is not being set by adding this at the end of my script... $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('POST FAIL')"; $connection->runQuery($query); So, now I know for certain my log out function is being skipped because in my database is the following data: if it were NOT being skipped, my data would show up like this: I know it is being skipped for two reasons, one the die() at the end of my first function, and two, if it were a success a "logOutSuccess" would be registered in the table. Any thoughts? One friend says it's a janky hosting company (hostgator.com). I personally like them because they are cheap and I'm a fan of cpanel. But, if that's the case??? Thanks in advance. -J

  • How to return ArrayList results from an IntentService

    - by gcl1
    I have an IntentService that loads up an ArrayList with data from a network source (AWS SDB tables). The ArrayList is in a global space -- accessible to both the calling Activity and the IntentService (like this: appState = ((App)getApplicationContext())). When the IntentService is done, it notifies the Activity through a ResultReceiver, and the Activity calls adapter.notifyDataChanged() to update the ListView. This solution works most of the time, ... but it violates the rule that only the UI thread should make changes to data underlying a ListView. So as it is, I sometimes get an error: "The content of the adapter has changed but ListView did not receive a notification." I think this must be a common situation. Please let me know if you have any suggestions or best practices for this problem. Here are three options I'm aware of: Keep the IntentService, and have it store the results in another "working" ArrayList, also in the global space. When the result is ready, the IntentService calls the ResultReceiver (on the UI thread), which can then: a) copy the result to the ArrayList associated with the ListView, and b) call adapter.notifyDataChanged(). CONS: I don't like the idea of putting temp/working data in a global space, and copying the result list seems inefficient. Keep the IntentService, and have it pass the results back through a bundle loaded with a ParcelableArrayList. CONS: I'm not sure if this approach would scale for very large result sets. It also requires copying the result list. Switch to a Service which builds a local copy of the result list. Have the Activity directly access the address space of the Service in order to read the result list. CON: Still requires copying results to the ArrayList associated with the ListView. Thank you.

  • What is the easiest way to add compression to WCF in Silverlight?

    - by caryden
    I have a silverlight 2 beta 2 application that accesses a WCF web service. Because of this, it currently can only use basicHttp binding. The webservice will return fairly large amounts of XML data. This seems fairly wasteful from a bandwidth usage standpoint as the response, if zipped, would be smaller by a factor of 5 (I actually pasted the response into a txt file and zipped it.). The request does have the "Accept-Encoding: gzip, deflate" - Is there any way have the WCF service gzip (or otherwise compress) the response? I did find this link but it sure seems a bit complex for functionality that should be handled out-of-the-box IMHO. OK - at first I marked the solution using the System.IO.Compression as the answer as I could never "seem" to get the IIS7 dynamic compression to work. Well, as it turns out: Dynamic Compression on IIS7 was working al along. It is just that Nikhil's Web Developer Helper plugin for IE did not show it working. My guess is that since SL hands the web service call off to the browser, that the browser handles it "under the covers" and Nikhil's tool never sees the compressed response. I was able to confirm this by using Fiddler which monitors traffic external to the browser application. In fiddler, the response was, in fact, gzip compressed!! The other problem with the System.IO.Compression solution is that System.IO.Compression does not exist in the Silverlight CLR. So from my perspective, the EASIEST way to enable WCF compression in Silverlight is to enable Dynamic Compression in IIS7 and write no code at all.

  • Comparing two Objects which implement the same interface for equality / equivalence - Design help

    - by gav
    Hi All, I have an interface and two objects implementing that interface, massively simplied; public interface MyInterface { public int getId(); public int getName(); ... } public class A implements MyInterface { ... } public class B implements MyInterface { ... } We are migrating from using one implementation to the other but I need to check that the objects of type B that are generated are equivalent to those of type A. Specifically I mean that for all of the interface methods an object of Type A and Type B will return the same value (I'm just checking my code for generating this objects is correct). How would you go about this? Map<String, MyInterface> oldGeneratedObjects = getOldGeneratedObjects(); Map<String, MyInterface> newGeneratedObjects = getNewGeneratedObjects(); // TODO: Establish that for each Key the Values in the two maps return equivalent values. I'm looking for good coding practices and style here. I appreciate that I could just iterate through one key set pulling out both objects which should be equivalent and then just call all the methods and compare, I'm just thinking there may be a cleaner, more extensible way and I'm interested to learn what options there might be. Would it be appropriate / possible / advised to override equals or implement Comparable? Thanks in advance, Gavin

  • C++ socket concurrent server

    - by gregpi
    Hi all; Im writing a concurrent server that's supposed to have a communication channel and a data channel. The client initially connect to the communication channel to authenticate, upon successful authentication, the client is then connected to the data channel to access data. My program is already doing that, and im using threads.My only issue is that if I try to connect another client, I get a "cannot bind : address already in use" error. I have it this way: PART A Client connect to port 4567 (and enter his login info). A thread spawn to handle the client(repeated for each client that connects). In the thread created, I have a function(let's call it FUNC_A) that checks the client's login info(dont worry about how the check is done), if successful, the thread starts the data server(listening on 8976) then sends an OK to the client, once received the client attempts to connect to the data server. PART B Once a client connect to the data server, from inside FUNC_A the client is accepted and another thread is spawn to handle the client's connection to the data server.(hopefully everything is clear). Now, all that is working fine. However, if I try to connect with second client when it gets to PART B I get a "cannot bind error: address already in use". I've tried so many different ways, I've even tried spawning a thread to start the data server and accept the client and then start another thread to handle that connection. still no luck. Please give me a suggestion as to what I'm doing wrong, how do I go about doing this or what's the best way to implement it. Thank you

  • Queries within queries: Is there a better way?

    - by mririgo
    As I build bigger, more advanced web applications, I'm finding myself writing extremely long and complex queries. I tend to write queries within queries a lot because I feel making one call to the database from PHP is better than making several and correlating the data. However, anyone who knows anything about SQL knows about JOINs. Personally, I've used a JOIN or two before, but quickly stopped when I discovered using subqueries because it felt easier and quicker for me to write and maintain. Commonly, I'll do subqueries that may contain one or more subqueries from relative tables. Consider this example: SELECT (SELECT username FROM users WHERE records.user_id = user_id) AS username, (SELECT last_name||', '||first_name FROM users WHERE records.user_id = user_id) AS name, in_timestamp, out_timestamp FROM records ORDER BY in_timestamp Rarely, I'll do subqueries after the WHERE clause. Consider this example: SELECT user_id, (SELECT name FROM organizations WHERE (SELECT organization FROM locations WHERE records.location = location_id) = organization_id) AS organization_name FROM records ORDER BY in_timestamp In these two cases, would I see any sort of improvement if I decided to rewrite the queries using a JOIN? As more of a blanket question, what are the advantages/disadvantages of using subqueries or a JOIN? Is one way more correct or accepted than the other?

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?

  • Cryptic Erlang Errors

    - by Jim
    Okay so I started learning erlang recently but am baffled by the errors it keeps returning. I made a bunch of changes but I keep getting errors. The syntax is correct as far as I can tell but clearly I'm doing something wrong. Have a look... -module(pidprint). -export([start/0]). dostuff([]) - receive begin - io:format("~p~n", [This is a Success]) end. sender([N]) - N ! begin, io:format("~p~n", [N]). start() - StuffPid = spawn(pidprint, dostuff, []), spawn(pidprint, sender, [StuffPid]). Basically I want to compile the script, call start, spawn the "dostuff" process, pass its process identifier to the "sender" process, which then prints it out. Finally I want to send a the atom "begin" to the "dostuff" process using the process identifier initially passed into sender when I spawned it. The errors I keep getting occur when I try to use c() to compile the script. Here they are.. ./pidprint.erl:6: syntax error before: '-' ./pidprint.erl:11: syntax error before: ',' What am I doing wrong?

  • SQL Server INSERT, Scope_Identity() and physical writing to disc

    - by TheBlueSky
    Hello everyone, I have a stored procedure that does, among other stuff, some inserts in different table inside a loop. See the example below for clearer understanding: INSERT INTO T1 VALUES ('something') SET @MyID = Scope_Identity() ... some stuff go here INSERT INTO T2 VALUES (@MyID, 'something else') ... The rest of the procedure These two tables (T1 and T2) have an IDENTITY(1, 1) column in each one of them, let's call them ID1 and ID2; however, after running the procedure in our production database (very busy database) and having more than 6250 records in each table, I have noticed one incident where ID1 does not match ID2! Although normally for each record inserted in T1, there is record inserted in T2 and the identity column in both is incremented consistently. The "wrong" records were something like that: ID1 Col1 ---- --------- 4709 data-4709 4710 data-4710 ID2 ID1 Col1 ---- ---- --------- 4709 4710 data-4709 4710 4709 data-4710 Note the "inverted", ID1 in the second table. Knowing not that much about SQL Server underneath operations, I have put the following "theory", maybe someone can correct me on this. What I think is that because the loop is faster than physically writing to the table, and/or maybe some other thing delayed the writing process, the records were buffered. When it comes the time to write them, they were wrote in no particular order. Is that even possible if no, how to explain the above mentioned scenario? If yes, then I have another question to rise. What if the first insert (from the code above) got delayed? Doesn't that mean I won't get the correct IDENTITY to insert into the second table? If the answer of this is also yes, what can I do to insure the insertion in the two tables will happen in sequence with the correct IDENTITY? I appreciate any comment and information that help me understand this. Thanks in advance.

  • Zend Framework - counting rows in select clause ?

    - by moogeek
    Hello! I'm investigating Zend Framework and currently stucked in counting resulting rows of sql query... Every method I try (from documentation and some blogposts and tutorials) returns an error (like Call to undefined function) or simply gives the incorrect value. I've tried this: $checkquery = $db->select() ->from('users', 'COUNT(*)') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=fetchRow($checkquery)->num; ...then this one: $checkquery = $db->select() ->from('users', '*') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=count($checkquery->fetchAll()); and even: $checkquery = $db->select() ->from('users', '*') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=$checkquery->fetchAll()->num; Also rowCount() and count(fetchRow()) and count(fetchAll()->toArray()). But always I got an error message or duplicate inserts in db in further insert function. So what is the correct way to do the resulting row calculation in select clause in Zend Framework 1.9 (I use this one) ?

  • Dynamically changing background color of a UIView

    - by EricM
    Hello- Here's my setup. I have a viewcontroller that I'm creating and adding as a subview. The viewcontroller presents some options that a user can chose from. The viewcontroller is being pushed in response to a "long press" gesture. Within the viewcontroller, I added a child UIView to group some other controls together so I can move them around the screen as a unit and, when they are displayed, center them on the location of the long press. Here is the code that instantiates the view controller, changes its location, and adds it as a subview: UserOptions *opts = [[UserOptions alloc] initWithNibName:@"UserOptions" bundle:nil]; [opts recenterOptions:location]; [self.view addSubview:opts.view]; That bit of code does create and push the viewcontroller, but the call to recenterOptions doesn't do anything. Here is that method: - (void) recenterOptions:(CGPoint)location { CGRect oldFrame = self.optionsView.frame; CGFloat newX = location.x; // + oldFrame.size.width / 2.0; CGFloat newY = location.y; // + oldFrame.size.height / 2.0; CGRect newFrame = CGRectMake(newX, newY, oldFrame.size.width, oldFrame.size.height); self.optionsView.frame = newFrame; } Note that self.optionsView is the child UIView that I added to the viewcontroller's nib. Does anyone know why I'm unable to change the location of the UIView? Regards, Eric

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by Justin Williams
    I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?

  • [Adobe Air] Can I catch a mouseUp event of an mx:Window that did not fire hte mouseDown?

    - by Irene
    Hi, In an AIR application, I have one mx:TileList with several images. What I need to do is let the user drag and drop one of the images on the desktop, giving a feeling of a desktop widget. Firstly I tried to implement this using dragStart etc, but in the end I think it is easier to handle mouseDown and mouseUp on the TileList. In general the whole setup works as desired. When a mouseDown is detected on the TileList, I create a transparent mx:Window containing the corresponding image, and call the startMove() on the Window to simulate a dragging behavior. If I release the mouse, the Window stops moving as desired. My problem is that now I want some visual feedback during dragging. It works while the Window is moving, however I can't find a way to stop it when the user releases the mouse. The mouseUp is not fired from the TileList, nor from the s:WindowedApplication. I also tried to add a listener to the Window itself, but still with no luck. Some code: private function onMouseDown(e:MouseEvent):void { trace ("down " + e.target); if (e.target is TileListItemRenderer) { // first create a dragWindow dragWindow.startGlow(); // then show some visual feedback dragWindow.moveWindow(e); // and start dragging } } private function onMouseUp(e:MouseEvent):void { trace("up " + e.target); dragWindow.stopGlow(); // <--------- Not called! } <mx:TileList id="photoTileList" mouseDown="onMouseDown(event)" mouseUp="onMouseUp(event)">

  • How to see external libraries code when debugging

    - by Sanva
    Hello!! First of all... this is my message #1 in this place, so... please be nice with me ;) I just started recently to study Gnome apps/libraries and I found that debuggers are an excellent way to learn, because seeing the code running helps a lot in understanding the structure of the program. But I have a problem. For example, debugging gnome-panel I found a lot of calls to external functions (basically the GTK+ functions), and although pretending to see all the code of all the functions applications like this call would be crazy, there are a lot that will be very interesting to see in action. The problem is that the debugger hasn't the code of those libraries loaded and it can't show it to me —at most it shows the line number where the execution is. I'm using Nemiver and when it tries to enter in an external function it claims because it can't find a file it supposed to be somewhere. For example, trying to enter in gtk_window_set_default_icon_name it tries to load /build/buildd/gtk+2.0-2.16.1/gtk/gtkwindow.c, and calling XSetIOErrorHandler, ../../src/ErrHndlr.c. So now I think that I'm doing something wrong... Why Nevimer are looking for those source files in those places?? My system does not even have the /build/buildd/ folders... and I don't know if I'm doing something wrong or I need to install somethig or what. Any suggestion? How do you debug this kind of applications? Best regards and thanks a lot for your time —and forgive me if my English is bad.

  • iPhone: Does it ever make sense for an object to retain its delegate?

    - by randombits
    According to the rules of memory management in a non garbage collected world, one is not supposed to retain a the calling object in a delegate. Scenario goes like this: I have a class that inherits from UITableViewController and contains a search bar. I run expensive search operations in a secondary thread. This is all done with an NSOperationQueue and subclasses NSOperation instances. I pass the controller as a delegate that adheres to a callback protocol into the NSOperation. There are edge cases when the application crashes because once an item is selected from the UITableViewController, I dismiss it and thus its retain count goes to 0 and dealloc gets invoked on it. The delegate didn't get to send its message in time as the results are being passed at about the same time the dealloc happens. Should I design this differently? Should I call retain on my controller from the delegate to ensure it exists until the NSOperation itself is dealloc'd? Will this cause a memory leak? Right now if I put a retain on the controller, the crashes goes away. I don't want to leak memory though and need to understand if there are cases where retaining the delegate makes sense. Just to recap. UITableViewController creates an NSOperationQueue and NSOperation that gets embedded into the queue. The UITableViewController passes itself as a delegate to NSOperation. NSOperation calls a method on UITableViewController when it's ready. If I retain the UITableViewController, I guarantee it's there, but I'm not sure if I'm leaking memory. If I only use an assign property, edge cases occur where the UITableViewController gets dealloc'd and objc_msgSend() gets called on an object that doesn't exist in memory and a crash is imminent.

  • Getting the last User ID in Zend Framework

    - by Ryan Murphy
    Using MySQL query browser, I manually made a table called users and input some date in the fields. I set the primary key to id and set it to auto increment. There are 3 rows, the highest id is 3. I then made the following class in the method directory to call upon the data in the table etc. class Application_Model_DbTable_User extends Zend_Db_Table_Abstract { protected $_name = 'user'; public function getLatestUserId() { $id = $this->getAdapter()->lastInsertId(); return $id; } } In the controller I do the following which gets the value generated by the method and lets the view access it: $usersDbModel = new Application_Model_DbTable_User(); $lastUserId = $usersDbModel->getLatestUserId(); $this->view->lastUserId = $lastUserId; In the view I then echo it to display it to the user: echo $this->lastUserId; However, even though my last id in the users table is 3. It displays 0. I have also tried: public function getLatestUserId() { $sql = 'SELECT max(id) FROM user'; $query = $this->query($sql); $result = $query->fetchAll(); return $result; } But this just throws out a server error. What have I done wrong? Am I missing something? Is there another way of doing this?

  • Sqlite iPhone data insertion problem

    - by Asad Khan
    Hi I have a function which basically tries to insert some data returned from a REST call. - (void)syncLocalDatabase{ NSString *file = [[NSBundle mainBundle] pathForResource:@"pickuplines" ofType:@"db"]; NSMutableString *query = [[NSMutableString alloc] initWithFormat:@""]; sqlite3 *database = NULL; char *errorMsg = NULL; if (sqlite3_open([file UTF8String], &database) == SQLITE_OK) { for(PickUpLine *pickupline in pickUpLines){ [query appendFormat:@"INSERT INTO pickuplines VALUES(%d,%d,%d,'%@','YES')", pickupline.line_id, pickupline.thumbsUps, pickupline.thumbsDowns, [pickupline.line stringByReplacingOccurrencesOfString:@"'" withString:@"`"]]; NSLog(query); int result = sqlite3_exec(database, [query UTF8String], NULL, NULL, &errorMsg); if (result!=SQLITE_OK) { printf("\n%s",errorMsg); sqlite3_free(errorMsg); } //sqlite3_step([query UTF8String]); [query setString:@""]; }//end for }//end if [query release]; sqlite3_close(database); } everything seems fine query string in log statement is also fine but the data does not gets inserted. Where as a counterpart of this function for select statement works well. Here is the counter part - (void)loadLinesFromDatabase{ NSString *file = [[NSBundle mainBundle] pathForResource:@"pickuplines" ofType:@"db"]; sqlite3 *database = NULL; if (sqlite3_open([file UTF8String], &database) == SQLITE_OK) { sqlite3_exec(database, "SELECT * FROM pickuplines", MyCallback, linesFromDatabase, NULL); } sqlite3_close(database); } I have implemented callback & it works fine. I am a little new to Sqlite can someone please point out what am I doing wrong. Thanx

  • Dismiss a custom dialog?

    - by YaW
    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • how to elegantly duplicate a graph (neural network)

    - by macias
    I have a graph (network) which consists of layers, which contains nodes (neurons). I would like to write a procedure to duplicate entire graph in most elegant way possible -- i.e. with minimal or no overhead added to the structure of the node or layer. Or yet in other words -- the procedure could be complex, but the complexity should not "leak" to structures. They should be no complex just because they are copyable. I wrote the code in C#, so far it looks like this: neuron has additional field -- copy_of which is pointer the the neuron which base copied from, this is my additional overhead neuron has parameterless method Clone() neuron has method Reconnect() -- which exchanges connection from "source" neuron (parameter) to "target" neuron (parameter) layer has parameterless method Clone() -- it simply call Clone() for all neurons network has parameterless method Clone() -- it calls Clone() for every layer and then it iterates over all neurons and creates mappings neuron=copy_of and then calls Reconnect to exchange all the "wiring" I hope my approach is clear. The question is -- is there more elegant method, I particularly don't like keeping extra pointer in neuron class just in case of being copied! I would like to gather the data in one point (network's Clone) and then dispose it completely (Clone method cannot have an argument though).

  • Adding a button bar at the bottom of ListView upon checkbox select (as in gmail app)??

    - by elto
    I have a ListView with custom adapter. In each row there is a checkbox and couple of textviews. I want user to give option to delete the check marked items, so as soon as soon clicks on one of the checkbox, I want a button bar to slide in from the bottom and stay at the bottom regardless of listview scroll. This is something like the email app behavior of Motorola Cliq and to some extent gmail app itself. I have tried adding a relativelayout (containing buttons) below the listview, which has visibility set to gone initially, but as soon as user checks a button, the visibility changes to "visible". I have added a slide-in animation to it too. It is working but problem is that it is overlapping the last element of the listview which user can not checkmark if the button bar has already become visible. So I tried to set the bottom margin of the listview equal to the height of the button bar when I'm changing the button bar visibility, which solves the problem of overlap, but now the checkbox behavior has gone weird. Clicking on one checkmark tries to checkmark another checkmark in the list for some weird reason. I noticed that this happens because as soon as I change the listview margin, list redraws itself, and during this new call to getView() method of adapter, things mess up. I wanted to ask if anyone has done something like this. What is the best method to add such button bar below list while keeping the slide-in animation intact. Also, What is the footer-view of listview and can that solve my problem?
