  • Regarding Toplink Fetching Policy

    - by Chandu
    Hi, I'm working for a Swing Project and the technologies used are netbeans with Toplink essentials, mysql. The Problem I'm facing is the entity object dosn't get updated after insertions take place while calling a getter collection of the foreign key property. Ex: I have 2 tables Table1,Table2. I have sno column, id column as a primary key in Table1 & is Foreign Key in Table2. Through find method I just get the particular sno object(existed in table 1) set some values persisted to table2 & committed the transaction. When I select the same sno object through find method & gets its collection from Table2 through the getTable2Collection() of the bean(as it is already created in bean by toplink essential) I'm unable to get the latest added record except that all other records of it are displayed. After I close the application & opening it then the new record gets reflected while calling the same sno through the above process. I came to know that this is a kind of lazy fetching and there should be some way of fetch policy to be changed to make the entity object get updated with the changes. So Please help me in this regard. Regards, Chandu

  • Linux Newbie: SSH or VNC for linux admin tasks

    - by Dirk
    Longtime Windows user, looking to get my feet wet with Linux. Since Windows makes comparatively little use of the command line, I'm naturally more comfortable with GUI tools for remote server administration tasks. However, before i rush out and install a VNC server on my Linux box, I want to get a sense of how many of Linux's various packages actually offer GUI front end. If not many, then it's probably not worth the effort.

  • Basic security practices for desktop Ubuntu

    - by Daisetsu
    Most of us know the basic security practices on Windows: use a limited account set a password disable unused services uninstall bloatware Antivirus / Antimalware etc. I haven't ran linux as my main desktop computer before, so I don't know how to properly secure it. I have heard linux is supposed to be more secure than Windows, but I know that the default settings of anything are rarely secure. What are some things I should do as a new Linux user to secure my desktop system from attack?

  • 'Invalid column name [ColumnName]' on a nested linq query.

    - by Joe
    I've got the following query: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault().Timestamp}) results in: SqlException: Invalid column name 'FieldAID' x 5 SqlException: Invalid column name 'FieldBID' x 5 SqlException: Invalid column name 'FieldCID' x 1 I've worked out it has to do with the last query to Timestamp because this works: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) The query has been simplified. The purpose is to group by a set of variables and then show the last time this grouping occured in the db. I'm using Linqpad 4 to generate these results so the Timestamp gives me a string whereas FirstOrDefault gives me the whole object which isn't ideal. Update On further testing I've noticed that the number and type of SQLException is related to the class created in the groupby clause. So, ATable .GroupBy(x=> new {FieldA = x.FieldAID}) .Select(x=>new {FieldA = x.Key.FieldA, last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) results in SqlException: Invalid column name 'FieldAID' x 5

  • Open Source Embedded Database Options for .Net Applications

    - by LonnieBest
    I have a .Net 4.0 WPF application that requires an embedded database. MS Access doesn't work on 64 bit Windows I'm told. And I having issues with SSCE: Unable to load DLL 'sqlceme35.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) sqlceme35.dll is installed into my application's program files directory, so I can't seem to figure out why Windows XP Pro doesn't see it. I was wondering about other embedded databases options I might use that work on both 32 and 64 bit windows. Any suggestions?

  • Implementing A Static NSOutlineView

    - by spamguy
    I'm having a hard time scraping together enough snippets of knowledge to implement an NSOutlineView with a static, never-changing structure defined in an NSArray. This link has been great, but it's not helping me grasp submenus. I'm thinking they're just nested NSArrays, but I have no clear idea. Let's say we have an NSArray inside an NSArray, defined as NSArray *subarray = [[NSArray alloc] initWithObjects:@"2.1", @"2.2", @"2.3", @"2.4", @"2.5", nil]; NSArray *ovStructure = [[NSArray alloc] initWithObjects:@"1", subarray, @"3", nil]; The text is defined in outlineView:objectValueForTableColumn:byItem:. - (id)outlineView:(NSOutlineView *)ov objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:(id)ovItem { if ([[[tableColumn headerCell] stringValue] compare:@"Key"] == NSOrderedSame) { // Return the key for this item. First, get the parent array or dictionary. // If the parent is nil, then that must be root, so we'll get the root // dictionary. id parentObject = [ov parentForItem:ovItem] ? [ov parentForItem:ovItem] : ovStructure; if ([parentObject isKindOfClass:[NSArray class]]) { // Arrays don't have keys (usually), so we have to use a name // based on the index of the object. NSLog([NSString stringWithFormat:@"%@", ovItem]); //return [NSString stringWithFormat:@"Item %d", [parentObject indexOfObject:ovItem]]; return (NSString *) [ovStructure objectAtIndex:[ovStructure indexOfObject:ovItem]]; } } else { // Return the value for the key. If this is a string, just return that. if ([ovItem isKindOfClass:[NSString class]]) { return ovItem; } else if ([ovItem isKindOfClass:[NSDictionary class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } else if ([ovItem isKindOfClass:[NSArray class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } } return nil; } The result is '1', '(' (expandable), and '3'. NSLog shows the array starting with '(', hence the second item. Expanding it causes a crash due to going 'beyond bounds.' I tried using parentForItem: but couldn't figure out what to compare the result to. What am I missing?

  • Encryption in Java & Flex

    - by Jef
    I want tp encrypt and decrypt string, with defined salt. But the result must be same if the code run in java and adobe flex. The main goal is: the app in adobe flex will be generate a string that can be decrypt in server using java. I use this flex library http://crypto.hurlant.com/demo/ Try to 'Secret Key' Tab. I want to use AES Encryption, 'CBC' or 'PKCS5'. var k:String = "1234567890123456"; var kdata:ByteArray = Hex.toArray(k); var txt:String = "hello"; var data:ByteArray = Hex.toArray(Hex.fromString(txt));; var name:String = "simple-aes-cbc"; var pad:IPad =new PKCS5(); var mode:ICipher = Crypto.getCipher(name, kdata, pad); pad.setBlockSize(mode.getBlockSize()); mode.encrypt(data); encrypted.text=Hex.fromArray(data); trace(Hex.fromArray(data)); And here is the code in java String plaintext = "hello"; String key = "1234567890123456"; SecretKey keyspec = new SecretKeySpec(key.getBytes(), "AES"); Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); cipher.init(Cipher.ENCRYPT_MODE,keyspec); byte[] encrypted = cipher.doFinal(plaintext.getBytes()); BASE64Encoder base64 = new BASE64Encoder(); String encodedString = base64.encode(encrypted); System.out.println(encodedString); Why the result is not same? Can you guys provide the sample with the same result both of java and flex (encrypt and decrypt)? And if I want to change the paramater, for example, from cbc to ebc, which line that need to be changed? Thanks!

  • Learning Objective-C: Need advice on populating NSMutableDictionary

    - by Zigrivers
    I am teaching myself Objective-C utilizing a number of resources, one of which is the Stanford iPhone Dev class available via iTunes U (past 2010 class). One of the home work assignments asked that I populate a mutable dictionary with a predefined list of keys and values (URLs). I was able to put the code together, but as I look at it, I keep thinking there is probably a much better way for me to approach what I'm trying to do: Populate a NSMutableDictionary with the predefined keys and values Enumerate through the keys of the dictionary and check each key to see if it starts with "Stanford" If it meets the criteria, log both the key and the value I would really appreciate any feedback on how I might improve on what I've put together. I'm the very definition of a beginner, but I'm really enjoying the challenge of learning Objective-C. void bookmarkDictionary () { NSMutableDictionary* bookmarks = [NSMutableDictionary dictionary]; NSString* one = @"Stanford University", *two = @"Apple", *three = @"CS193P", *four = @"Stanford on iTunes U", *five = @"Stanford Mall"; NSString* urlOne = @"http://www.stanford.edu", *urlTwo = @"http://www.apple.com", *urlThree = @"http://cs193p.stanford.edu", *urlFour = @"http://itunes.stanford.edu", *urlFive = @"http://stanfordshop.com"; NSURL* oneURL = [NSURL URLWithString:urlOne]; NSURL* twoURL = [NSURL URLWithString:urlTwo]; NSURL* threeURL = [NSURL URLWithString:urlThree]; NSURL* fourURL = [NSURL URLWithString:urlFour]; NSURL* fiveURL = [NSURL URLWithString:urlFive]; [bookmarks setObject:oneURL forKey:one]; [bookmarks setObject:twoURL forKey:two]; [bookmarks setObject:threeURL forKey:three]; [bookmarks setObject:fourURL forKey:four]; [bookmarks setObject:fiveURL forKey:five]; NSString* akey; NSString* testString = @"Stanford"; for (akey in bookmarks) { if ([akey hasPrefix:testString]) { NSLog(@"Key: %@ URL: %@", akey, [bookmarks objectForKey:akey]); } } } Thanks for your help!

  • Getting black images with selenium.captureScreenshot

    - by Lidia
    I'm executing selenium tests with testng, that are started on a remote system with Selenium RC via hudson (with ssh connection). The remote system is windows xp with MKS Toolkit installed, hence ssh. Tests are NOT executed as a windows service. I've tried using both captureScreenshot and captureEntirePageScreenshot methods. The first one always produces a black image. The second one creates the correct screen shot but it only works on Firefox and our tests usually pass on Firefox and fail in other browsers, so it is crucial to capture screen shots for the other browsers (mainly IE and Safari). The tests are ran in parallel, with many browser windows open at the same time. I'm not certain if this is what's causing the problem. Any thoughts will be appreciated.

  • Snow Leopard not reading NTFS

    - by dtmunir
    I just upgraded a brand new Macbook Pro that I bought with 10.5 installed to Snow Leopard. After doing the upgrade I am trying to access NTFS partitions on my external hard drive but they are just not showing up. I went ahead and installed Windows 7 using Parallels, and I can access the NTFS partitions from within Windows, but not from Mac OS X. I know that Snow Leopard should be able to at least read NTFS drives, so what is going on here?

  • ObjC: Alloc instance of Class and performing selectors on it leads to __CFRequireConcreteImplementat

    - by Arakyd
    Hi, I'm new to Objective-C and I'd like to abstract my database access using a model class like this: @interface LectureModel : NSMutableDictionary { } -(NSString*)title; -(NSDate*)begin; ... @end I use the dictionary methods setValue:forKey: to store attributes and return these in the getters. Now I want to read these models from a sqlite database by using the Class dynamically. + (NSArray*)findBySQL:(NSString*)sql intoModelClass:(Class)modelClass { NSMutableArray* models = [[[NSMutableArray alloc] init] autorelease]; sqlite3* db = sqlite3_open(...); sqlite3_stmt* result = NULL; sqlite3_prepare_v2(db, [sql UTF8String], -1, &result, NULL); while(sqlite3_step(result) == SQLITE_ROW) { id modelInstance = [[modelClass alloc] init]; for (int i = 0; i < sqlite3_column_count(result); ++i) { NSString* key = [NSString stringWithUTF8String:sqlite3_column_name(result, i)]; NSString* value = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(result, i)]; if([modelInstance respondsToSelector:@selector(setValue:forKey:)]) [modelInstance setValue:value forKey:key]; } [models addObject:modelInstance]; } sqlite3_finalize(result); sqlite3_close(db); return models; } Funny thing is, the respondsToSelector: works, but if I try (in the debugger) to step over [modelInstance setValue:value forKey:key], it will throw an exception, and the stacktrace looks like: #0 0x302ac924 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ #1 0x991d9509 in objc_exception_throw #2 0x302d6e4d in __CFRequireConcreteImplementation #3 0x00024d92 in +[DBManager findBySQL:intoModelClass:] at DBManager.m:114 #4 0x0001ea86 in -[FavoritesViewController initializeTableData:] at FavoritesViewController.m:423 #5 0x0001ee41 in -[FavoritesViewController initializeTableData] at FavoritesViewController.m:540 #6 0x305359da in __NSFireDelayedPerform #7 0x302454a0 in CFRunLoopRunSpecific #8 0x30244628 in CFRunLoopRunInMode #9 0x32044c31 in GSEventRunModal #10 0x32044cf6 in GSEventRun #11 0x309021ee in UIApplicationMain #12 0x00002988 in main at main.m:14 So, what's wrong with this?

  • Google App Engine: Unit testing concurrent access to memcache

    - by Phuong Nguyen de ManCity fan
    Would you guys show me a way to simulating concurrent access to memcache on Google App Engine? I'm trying with LocalServiceTestHelpers and threads but don't have any luck. Every time I try to access Memcache within a thread, then I get this error: ApiProxy$CallNotFoundException: The API package 'memcache' or call 'Increment()' was not found I guess that the testing library of GAE SDK tried to mimic the real environment and thus setup the environment for only one thread (the thread that running the test) which cannot be seen by other thread. Here is a piece of code that can reproduce the problem package org.seamoo.cache.memcacheImpl; import org.testng.Assert; import org.testng.annotations.AfterMethod; import org.testng.annotations.BeforeMethod; import org.testng.annotations.Test; import com.google.appengine.api.memcache.MemcacheService; import com.google.appengine.api.memcache.MemcacheServiceFactory; import com.google.appengine.tools.development.testing.LocalMemcacheServiceTestConfig; import com.google.appengine.tools.development.testing.LocalServiceTestHelper; public class MemcacheTest { LocalServiceTestHelper helper; public MemcacheTest() { LocalMemcacheServiceTestConfig memcacheConfig = new LocalMemcacheServiceTestConfig(); helper = new LocalServiceTestHelper(memcacheConfig); } /** * */ @BeforeMethod public void setUp() { helper.setUp(); } /** * @see LocalServiceTest#tearDown() */ @AfterMethod public void tearDown() { helper.tearDown(); } @Test public void memcacheConcurrentAccess() throws InterruptedException { final MemcacheService service = MemcacheServiceFactory.getMemcacheService(); Runnable runner = new Runnable() { @Override public void run() { // TODO Auto-generated method stub service.increment("test-key", 1L, 1L); try { Thread.sleep(200L); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } service.increment("test-key", 1L, 1L); } }; Thread t1 = new Thread(runner); Thread t2 = new Thread(runner); t1.start(); t2.start(); while (t1.isAlive()) { Thread.sleep(100L); } Assert.assertEquals((Long) (service.get("test-key")), new Long(4L)); } }

  • Using SQLLite transactions I/O Error

    - by james.ingham
    I currently have a client / server setup where the client sends data to the server and then the server saves the data to a SQLite database file. To do this I am using transactions which works fine in windows 7 when I run around 30 clients (each client sending data back between 5 - 30 seconds). When using the same software in Windows XP, I can get/set data multiple times with no problems until I run around 20 clients I start to get Windows Delayed wrote failed errors: This fires an exception on the server: I'm assuming this is either something to do with XP or a hardware issue on the machine i'm running XP. Does anyone have any advice to avoid this? Or if I should just catch the exception and retry saving the data? Thanks

  • Sleep or Hibernate for a laptop

    - by Tim
    I was wondering whether it is better to put a laptop into sleep or hibernation in Windows 7, and suspend or hibernate in Ubuntu: when carrying the laptop in a backpack and walking or slow-running to another place in around 15 minutes, Or just when the lid is closed. My concerns are if the heat generated and accumulated and bumping from transmit will do harm to the laptop, and I can miss other important factors. Is sleep in Windows 7 same as suspend in Ubuntu? Thanks and regards!

  • 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

  • Selenium Grid not always using all of its registered RC's, why?

    - by BenA
    My Selenium Grid setup is as follows (all VMs) VM1 - Windows 7 x64 - Grid Hub + 2 RCs registering the default *firefox environment VM2 - Windows XP x32 - 2 RCs registering the default *firefox environment VM3 - Windows XP x32 - 2 RCs registering the default *firefox environment I'm happily using Mbunit and Gallio to drive the Grid, but my problem is that sometimes the Grid hub will stop passing executions over to 1 or more of the RCs, despite their showing available on the hub console. They seem to be happily maintaining their heartbeat back to the hub, but they're never asked to do any more work. This is after they had been executing tests earlier in the test run. Does anybody have any ideas why this should happen? In every case I've observed this behaviour, the last test an RC executed, before it then seemingly gets ignored by the hub, passed, and the session was successfully closed. Interestingly, whenever it happens to more than 1 of the RCs, its always (so far) been the pair that are running on the same VM. Yet they're managing to maintain their heartbeat, so it isn't a network connectivity problem. Any help would be greatly appreciated!

  • WSS having two OWSTIMER.EXE (v11 and v12) running at the same time

    - by Nelson Reis
    I've just found that my WSS 3.0 server had two OWSTIMER.EXE services running: SharePoint Timer Service v11 "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\60\BIN\OWSTIMER.EXE" Windows SharePoint Services Timer v12 "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\BIN\OWSTIMER.EXE" Since I'm running WSS v3, I was expecting to have only one SharePoint Timer instance, and that should be the one in th "12" folder. Should I just stop the other service and keep only the "Windows SharePoint Services Timer" (v12) running?

  • splitting off an emacs window into a new frame

    - by user38983
    From a frame displaying multiple windows, I'd like to be able to 'break' one of the windows off into another frame, perhaps with a modifier-click on the modeline, where the window would now have its own frame but hold the same buffer and position. I was wondering if this behavior was available somewhere in the standard library, if there was an extension for it, or perhaps if a small elisp function would work.

  • very quickly getting total size of folder

    - by freakazo
    I want to quickly find the total size of any folder using python. def GetFolderSize(path): TotalSize = 0 for item in os.walk(path): for file in item[2]: try: TotalSize = TotalSize + getsize(join(item[0], file)) except: print("error with file: " + join(item[0], file)) return TotalSize That's the simple script I wrote to get the total size of the folder, it took around 60 seconds (+-5 seconds). By using multiprocessing I got it down to 23 seconds on a quad core machine. Using the Windows file explorer it takes only ~3 seconds (Right click- properties to see for yourself). So is there a faster way of finding the total size of a folder close to the speed that windows can do it? Windows 7, python 2.6 (Did searches but most of the time people used a very similar method to my own) Thanks in advance.

  • Delphi - OnKeyPress occurs before TStringGrid updates cell with new character

    - by JMTyler
    Coding in Delphi, attaching an OnKeyPress event handler to a TStringGrid: The OnKeyPress event fires before the grid cell that the user is typing into has actually updated its value with the key that has been pressed. This is obviously a problem, when I want to know what the contents of that cell are at this moment, as in, as the user modifies it. The "hacked" solution is simple, if you're not considering every detail: just grab the value from the cell and, since the OnKeyPress event comes along with a Key parameter, append that value to the end - now you have the current value of the cell! False. What if the user has selected all the text in the cell (ie: "foo") and they are now typing 'b'. Since they selected the text, it will be erased and replaced with the letter 'b'. However, the value of the cell will still display as "foo" in OnKeyPress, and the value of Key will be 'b', so the above logic would lead the application to conclude that the cell now contains "foob", which we know is not true. So. Does anybody know how to get around this problem? Is there a way to make OnKeyPress react after the grid's contents have been updated, or perhaps a way to force an update at the start of the handler? I am desperately avoiding the use of the OnKeyUp event here, so any suggestions aside from that would be greatly appreciated.
