  • Javascript: Controlling the order that event handlers / listeners are exeucted in

    - by LRE
    Once again the IE Monster has hit me with an odd problem. I'm writing some changes into an asp.net site I inherited a while back. One of the problems is that in some pages there are several controls that add javascript functions as handlers to the onload event (using YUI if that matters). Some of those event handlers assume certain other functions have been executed. This is well and good in Firefox and IE7 as the handlers seem to execute in order of registration. IE8 on the other hand does this backwards. I could go with some kind of double-checking approach but given the controls are present in several pages I feel that'd create even more dependencies. So I've started cooking up my own queue class that I push the functions to and can control their execution order. Then I'll register an onload handler that instructs the queue to execute in my preferred order. I'm part way through that and have started wondering 2 things: Am I going OTT? Am I reinventing the wheel? Anyone have any insights? Any clean solutions that allow me to easily enforce execution order?

  • Windows could not start Apache 2 on the local computer

    - by andig
    After installing PHP 5.3, Windows is unable to start Apache 2.2. Apache's error log is empty, no error message on startup: C:\Programme\Apache\bin>httpd -k start C:\Programme\Apache\bin>httpd -k stop The Apache2.2 service is not started. C:\Programme\Apache\bin>httpd -k config Reconfiguring the Apache2.2 service The Apache2.2 service is successfully installed. Testing httpd.conf.... Errors reported here must be corrected before the service can be started. I have no clue where to look for the cause. php5apache2_2.dll is copied to the Apache modules folder. The configuration looks like this: LoadModule php5_module modules/php5apache2_2.dll PHPIniDir "C:/programme/php" Where and how can I start diagnosis? The only hint I have so far is that startup fails as soon as a PHP module is enabled in the configuration. Is there a way to get more details out of the Apache startup process? This is the http.conf: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "C:/Programme/Apache" will be interpreted by the # server as "C:/Programme/Apache/logs/foo.log". # # NOTE: Where filenames are specified, you must use forward slashes # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). # If a drive letter is omitted, the drive on which httpd.exe is located # will be used by default. It is recommended that you always supply # an explicit drive letter in absolute paths to avoid confusion. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "C:/Programme/Apache" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen 80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule asis_module modules/mod_asis.so LoadModule auth_basic_module modules/mod_auth_basic.so #LoadModule auth_digest_module modules/mod_auth_digest.so #LoadModule authn_alias_module modules/mod_authn_alias.so #LoadModule authn_anon_module modules/mod_authn_anon.so #LoadModule authn_dbd_module modules/mod_authn_dbd.so #LoadModule authn_dbm_module modules/mod_authn_dbm.so LoadModule authn_default_module modules/mod_authn_default.so LoadModule authn_file_module modules/mod_authn_file.so #LoadModule authnz_ldap_module modules/mod_authnz_ldap.so #LoadModule authz_dbm_module modules/mod_authz_dbm.so LoadModule authz_default_module modules/mod_authz_default.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authz_host_module modules/mod_authz_host.so #LoadModule authz_owner_module modules/mod_authz_owner.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule autoindex_module modules/mod_autoindex.so #LoadModule cache_module modules/mod_cache.so #LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule cgi_module modules/mod_cgi.so #LoadModule charset_lite_module modules/mod_charset_lite.so #LoadModule dav_module modules/mod_dav.so #LoadModule dav_fs_module modules/mod_dav_fs.so #LoadModule dav_lock_module modules/mod_dav_lock.so #LoadModule dbd_module modules/mod_dbd.so #LoadModule deflate_module modules/mod_deflate.so LoadModule dir_module modules/mod_dir.so #LoadModule disk_cache_module modules/mod_disk_cache.so #LoadModule dumpio_module modules/mod_dumpio.so LoadModule env_module modules/mod_env.so #LoadModule expires_module modules/mod_expires.so #LoadModule ext_filter_module modules/mod_ext_filter.so #LoadModule file_cache_module modules/mod_file_cache.so #LoadModule filter_module modules/mod_filter.so #LoadModule headers_module modules/mod_headers.so #LoadModule ident_module modules/mod_ident.so #LoadModule imagemap_module modules/mod_imagemap.so LoadModule include_module modules/mod_include.so #LoadModule info_module modules/mod_info.so LoadModule isapi_module modules/mod_isapi.so #LoadModule ldap_module modules/mod_ldap.so #LoadModule logio_module modules/mod_logio.so LoadModule log_config_module modules/mod_log_config.so #LoadModule log_forensic_module modules/mod_log_forensic.so #LoadModule mem_cache_module modules/mod_mem_cache.so LoadModule mime_module modules/mod_mime.so #LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule negotiation_module modules/mod_negotiation.so #LoadModule proxy_module modules/mod_proxy.so #LoadModule proxy_ajp_module modules/mod_proxy_ajp.so #LoadModule proxy_balancer_module modules/mod_proxy_balancer.so #LoadModule proxy_connect_module modules/mod_proxy_connect.so #LoadModule proxy_ftp_module modules/mod_proxy_ftp.so #LoadModule proxy_http_module modules/mod_proxy_http.so #LoadModule proxy_scgi_module modules/mod_proxy_scgi.so #LoadModule reqtimeout_module modules/mod_reqtimeout.so #LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so #LoadModule speling_module modules/mod_speling.so #LoadModule ssl_module modules/mod_ssl.so #LoadModule status_module modules/mod_status.so #LoadModule substitute_module modules/mod_substitute.so #LoadModule unique_id_module modules/mod_unique_id.so #LoadModule userdir_module modules/mod_userdir.so #LoadModule usertrack_module modules/mod_usertrack.so #LoadModule version_module modules/mod_version.so #LoadModule vhost_alias_module modules/mod_vhost_alias.so #!!

  • ActiveX control loading but not activating correctly (only when using in Reg Free COM)

    - by embnut
    I have an ActiveX control (created using C#) that I am adding to a form in Visual FoxPro using late binding. It works without problems when I register the control. I want to use reg free COM and created necessary manifest files. Now it load and displays in an inactive state until I double click or programatically activate it. I don't think it has anything to do with the reg free com manifest files. However is there something I need to do to set it up before/after making the late binding call AddObject()? this.AddObject('OleControl1', 'oleControl', 'SomeCompany.SomeOleControl') When I check the OleTypeAllowed Property of the OleControl created by AddObject() it is 1 (Embedded OLE object) instead of -2 (ActiveX object). So the OleControl got instantiated to the wrong type. I also tried the following: DEFINE(d) a subclass of OleControl and set the property OleTypeAllowed = -2. Used late binding to load the control. It did not work as required. The OleTypeAllowed came back as 1 Registered the ActiveX control. Added the ActiveX control to the project as a subclass using the visual editor. Unregistered the control. Used late binding to load the control. It did not work as required. The OleTypeAllowed came back as 1. Is it possible to load the OleControl as a ActiveX control? Any input from VB that I can convert to FoxPro would also be appreciated.

  • Help with editing data in entity framework.

    - by Levelbit
    Title of this question is simple because there is no an easy explanation for what I'm trying to ask you. I hope you'll understand in the end :). I have to tables in my database: Company and Location (relationship:one to many) and corresponding entity sets. In my wpf application I have some datagrid which I want to fill with locations and to be able to edit every row in separate window as some form of details view (so I don't want to edit my data in datagrid). I did this by accessing Location entity from selected row and creating a new Location entity and then I copy properties from original entity to newly created. Something like cloning the object. After editing if I press OK changed data is copied to original object back, and if I press Cancel nothing happens. Of course, you probably thinking I could use NoTracking option and AttachAsModified method as was mentioned as solution in some earlier questions(see:http://stackoverflow.com/questions/803022/changing-entities-in-the-entityframework) by Alex James, but lets say I had some problems about that and I have my own reasons for doing this. Finally, because navigation property(Company) of my location entity is assigned to newly created location object(during cloning) from some reason in object context additional object as copy of object I want to edit from datagrid is created without my will(similar problem :http://blogs.msdn.com/alexj/archive/2009/12/02/tip-47-how-fix-up-can-make-it-hard-to-change-relationships.aspx). So, when I do ObjectContext.SaveChanges it inserts additional row of data into my database table Location, the same as the one i wanted to edit. I read about sth like this, but I don't quite understand why is that and how to block or override this. I hope I was clear as I could. Please, solutions or some other ideas.

  • Toolbar hiding on rotated UISplitView DetailView

    - by Gerry
    I've based my app on Apple's SplitView project type. I have a TableView as the Master, and am using different types of views as the Detail view. To select types of detail view, I'm using the fancy concept of buttons on my DetailView toolbar. When the DetailView is derived from UIViewController, everything is good. When the DetailView derives from UIViewController, but contains a UITableView then I have problems. In portrait view the toolbar is visible. In landscape mode the toolbar is hidden, even though the Tableview is moved down to allow space for it. The UIToolbar and UITableView are both defined in my NIB file which is loaded to create the detail view. Why is my toolbar invisible in landscape? BTW, is this the best way to choose Detail view types with UISplitView? Bonus question, what if selecting a row in my DetailView tableview should bring up another View, I can't push it like I would with a NaviagtionController, so how do I go back to the detail tableview? Thanks, Gerry

  • Anyone got a nifty credit expiry algorithm?

    - by garethkeenan
    Our website uses a credit system to allow users to purchase inexpensive digital goods (eg. photos). We use credits, rather than asking the user to pay for items individually, because the items are cheap and we are trying to keep our credit-card/PayPal overhead low. Because we aren't a bank, we have to expire credits after a certain amount of time. We expire deposit credits after a year, but other types of credits (bonuses, prizes, refunds) may have a different shelf-life. When a buyer buys an item, we spend the credit that is going to expire first. Our current system keeps track of every deposit by storing the original value and the remainder to be spent. We keep a list of all purchases as well, of course. I am currently moving to a system which is much more like a traditional double-entry accounting system. A deposit will create a ledger item, increasing the user's 'spending' account balance. Every purchase will also create a ledger item, decreasing the user's 'spending' account balance. The new system has running balances, while the old system does not, which greatly improves our ability to find problems and do reconciliations. We do not want to use the old system of keeping a 'remainder' value attached to each deposit record because it is inefficient to replay a user's activities to calculate what the remainder of each deposit is over time (for the user's statement). So, after all of this verbose introduction, my question is "Does anyone else out there have a similar system of expiring credits?" If you could describe how you calculate expired credits it would be a great help. If all expired credits had the exact same shelf life, we would be able to calculate the expired amount using: Total Deposits - Total Spending - Deposits Not Due To Expire = Amount to Expire However, because deposits can have different shelf lives, this formula does not work because more than one deposit can be partially spent at any given time.

  • glitchy stuttery iphone game loop

    - by Adam
    This is a problem I've been trying to solve for a few days now, and I've looked at the various solutions on stackoverflow and nothing has really seemed to work for me. I'm making an iPhone game with OpenGLES graphics and accelerometer input, at this point it's very simple, but the rendering is already pretty bad... it stutters and seems to jump back or forward in time. It doesn't happen a lot, but it happens enough to be a problem. I mean, who wants to play a game where a bullet gets magically transported into the player, and then it's game over? No one. I've tried using NSTimer for the game loop, I've tried using a separate thread (with a frame rate and continuously) I've tried using different frame rates, from 30FPS to 60FPS (It seems to have a max frame rate around 45FPS, but no problems at 30FPS) I've tried using timeIntervalSince1970 and CFGetAbsoluteTime to measure loop time, with no noticeable diffence Anyone have any ideas on what is the best way to get this looking better? One of the posts I've read suggested running the simulation at a fixed frame rate and then just render as fast as possible, does that seem like a good idea?

  • Why is WMDC/ActiveSync so flaky?

    - by Ira Rainey
    I'm developing a Windows Mobile app using the .NET Compact Framework 3.5 and VS2008, and for debugging using the Device Emulator V3, on Win7, and seem to have constant problems with Windows Mobile Device Centre (6.1) connecting. Using the Emulator Manager (9.0.21022.8) I cradle the device using DMA in WMDC. The problem is it's so flaky at actually connecting that it's becoming a pain. I find that when I turn my computer on, before I can get it to connect I have to open up WMDC, disable Connect over DMA, close WMDC down, reopen it again, and then it might cradle. Often I have to do this twice before it will cradle. Once it's cradled it's generally fine, but nothing seems consistent in getting it to connect. Connecting with physical devices is often better, although not always. If I plug a PDA into a USB socket other than the one it was originally plugged into then it won't connect at all. Often the best/most reliable connection method seems to be over Bluetooth, but that's quite slow. Anybody got any tips or advice?

  • Random encounter not so random

    - by DoomStone
    Hello i am having some problems generating random numbers with C# Now i have this function. public Color getRandomColor() { Color1 = new Random().Next(new Random().Next(0, 100), new Random().Next(200, 255)); Color2 = new Random().Next(new Random().Next(0, 100), new Random().Next(200, 255)); Color3 = new Random().Next(new Random().Next(0, 100), new Random().Next(200, 255)); Color color = Color.FromArgb(Color1, Color2, Color3); Console.WriteLine("R: " + Color1 + " G: " + Color2 + " B: " + Color3 + " = " + color.Name); return color; } Now you might notice that there are ALOT of new Random() there, that is because i want to weed out the probability that it could be a same instance error. I now run this function 8 times, a couple of times. Now here are the out puts.

  • Newbie python error in regards to import

    - by TylerW
    Hello. I'm a python newbie and starting out with using the Bottle web framework on Google App Engine. I've been messing with the super small, super easy Hello World sample and have already ran into problems. Heh. I finally got the code to work with this... import bottle from bottle import route from google.appengine.ext.webapp import util @route('/hello') def hello(): return "Hello World!" util.run_wsgi_app(bottle.default_app()) My question is, I thought I could just go 'import bottle' without the second line. But if I take the second line out, I get a NameError. Or if I do 'from bottle import *', I still get the error. bottle is just a single file called 'bottle.py' in my site's root directory. So neither of these work.... import bottle from google.appengine.ext.webapp import util @route('/hello') def hello(): return "Hello World!" util.run_wsgi_app(bottle.default_app()) Or from bottle import * from google.appengine.ext.webapp import util @route('/hello') def hello(): return "Hello World!" util.run_wsgi_app(bottle.default_app()) The error message I get is... Traceback (most recent call last): File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3180, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3123, in _Dispatch base_env_dict=env_dict) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 515, in Dispatch base_env_dict=base_env_dict) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2382, in Dispatch self._module_dict) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2292, in ExecuteCGI reset_modules = exec_script(handler_path, cgi_path, hook) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2188, in ExecuteOrImportScript exec module_code in script_module.dict File "/Users/tyler/Dropbox/sites/dietgrid/code2.py", line 4, in @route('/hello') NameError: name 'route' is not defined So am I wrong in thinking it should be able to work the other ways or no?

  • Comet Jetty/Tomcat, having some browser issues with Firefox and Chrome

    - by ages04
    I am exploring the use of Comet for a project I am working on. I tried creating a test application first using Tomcat6 and CometProcessor API and then with Jetty7 Continuations. The application is kind of working on both but I am having some issues with the actual display of messages. I used the technique of creating an XMLHttpRequest Connection and keeping it open all the time so the server can continuously push data to all the clients connected whenever it is available. My client side code is something similar to this: function fn(){ var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if (xhr.readyState==3){ document.getElementById('dv').innerHTML =(xhr.responseText); } if (xhr.readyState==4){ alert ('done'); } } xhr.open("GET", "First", true); xhr.send(null); } I found this thing of using readyState 3 somewhere online. I am facing 2 problems currently: In Firefox this code works perfectly. But if I open a new tab or even a new browser window, it does not make a new connection to the server and nothing shows up on the new tab or window, only the first tab/window gets the display. I used wireshark to check this and its shows only 1 connection even after the 2nd tab is opened. I am unable to understand why this would happen. I have read about the 2 connection limit, but here there is only one connection. Secondly in Chrome, the above code does not work, and the callback is not invoked for readystate of 3, only when the connection is closed by the server i get the output. I would also like to ask which is the best way/framework for doing Comet with Java. I am currently using jQuery on the client side. Any suggestions would be greatly appreciated!! Thanks

  • django shopping cart as a beginner

    - by Jacques Knie
    Hi, i'm quite new to django and trying to add a shopping cart to a simple webshop. What I need is a simple cart that can be filled and presents its content, which is then sent to the vendor via email. So Satchmo might be too big for this task. Therefore i chose django-cart (http://code.google.com/p/django-cart/) which causes some problems now. 1. Is django-cart the right thing? Or are there any better approaches to this task? 2. As I am a beginner even django-cart makes me struggle. I used the view and the template of the django-cart-website, but writing a form that can be used to add products to the cart took me hours. I probably need help in understanding the general layout of a shopping cart and its integration into a website. 3. Two more specific questions: Is it possible to dynamically populate a formfield in a template (e.g. with {{ object.id }})? Is django-cart able to change (update) the contents of a cart? I hope it's not too many questions at once. Thanks in advance Jacques

  • How can I write classes that don't rely on "global" variables?

    - by Joel
    When I took my first programming course in university, we were taught that global variables were evil & should be avoided at all cost (since you can quickly develop confusing and unmaintainable code). The following year, we were taught object oriented programming, and how to create modular code using classes. I find that whenever I work with OOP, I use my classes' private variables as global variables, i.e., they can be (and are) read and modified by any function within the class. This isn't really sitting right with me, as it seems to introduce the same problems global variables had in languages like C. So I guess my question is, how do I stop writing classes with "global" variables? Would it make more sense to pretend I'm writing in a functional language? By this I mean having all functions take parameters & return values instead of directly modifying class variables. If I need to set any fields, I can just take the output of the function and assign it instead of having the function do it directly. This seems like it might make more maintainable code, at least for larger classes. What's common practice? Thanks!

  • Optimizing code using PIL

    - by freakazo
    Firstly sorry for the long piece of code pasted below. This is my first time actually having to worry about performance of an application so I haven't really ever worried about performance. This piece of code pretty much searches for an image inside another image, it takes 30 seconds to run on my computer, converting the images to greyscale and other changes shaved of 15 seconds, I need another 15 shaved off. I did read a bunch of pages and looked at examples but I couldn't find the same problems in my code. So any help would be greatly appreciated. From the looks of it (cProfile) 25 seconds is spent within the Image module, and only 5 seconds in my code. from PIL import Image import os, ImageGrab, pdb, time, win32api, win32con import cProfile def GetImage(name): name = name + '.bmp' try: print(os.path.join(os.getcwd(),"Images",name)) image = Image.open(os.path.join(os.getcwd(),"Images",name)) except: print('error opening image;', name) return image def Find(name): image = GetImage(name) imagebbox = image.getbbox() screen = ImageGrab.grab() #screen = Image.open(os.path.join(os.getcwd(),"Images","Untitled.bmp")) YLimit = screen.getbbox()[3] - imagebbox[3] XLimit = screen.getbbox()[2] - imagebbox[2] image = image.convert("L") Screen = screen.convert("L") Screen.load() image.load() #print(XLimit, YLimit) Found = False image = image.getdata() for y in range(0,YLimit): for x in range(0,XLimit): BoxCoordinates = x, y, x+imagebbox[2], y+imagebbox[3] ScreenGrab = screen.crop(BoxCoordinates) ScreenGrab = ScreenGrab.getdata() if image == ScreenGrab: Found = True #print("woop") return x,y if Found == False: return "Not Found" cProfile.run('print(Find("Login"))')

  • PCA extended face recognition

    - by cMinor
    The state of the art says that we can use PCA to perform face recognition. like this, this or this I am working with a project that involves training a classifier to detect a person who is wearing glasess or hats or even a mustache. The purpose of doing this is to detect when a person that has robbed a bank, store, or have commeted some sort of crime(s) (we have their image in a database), enters a certain place ( historically we know these guys have robbed, so we should take care to avoid problems). We came first to have a distributed database with all images of criminals, then I thought to have a layer of them clasifying these criminals using accesories like hats, mustache or anything that hides their face etc... Then, to apply that knowledge to detect when a particular or a suspect person enters a comercial place. ( In practice when someone is going to rob not all the times they are using an accesorie...) What do you think about this idea of doing PCA to first detect principal components of the face and then the components of an accesory. I was thinking that maybe a probabilistic approach is better so we can compute the probability the criminal is the person that entered a place and call the respective authorities.

  • Doctrine unsigned validation error storing created_at

    - by Alex Dean
    Hi, I'm having problems with the Timestampable functionality in Doctrine 1.2.2. The error I get on trying to save() my Record is: Uncaught exception 'Doctrine_Validator_Exception' with message 'Validation failed in class XXX 1 field had validation error: * 1 validator failed on created_at (unsigned) ' in ... I've created the relevant field in the MySQL table as: created_at DATETIME NOT NULL, Then in setTableDefinition() I have: $this->hasColumn('created_at', 'timestamp', null, array( 'type' => 'timestamp', 'fixed' => false, 'unsigned' => false, 'primary' => false, 'notnull' => true, 'autoincrement' => false, )); Which is taken straight from the output of generateModelsFromDb(). And finally my setUp() looks like: public function setUp() { parent::setUp(); $this->actAs('Timestampable', array( 'created' => array( 'name' => 'created_at', 'type' => 'timestamp', 'format' => 'Y-m-d H:i:s', 'disabled' => false, 'options' => array() ), 'updated' => array( 'disabled' => true ))); } (I've tried not defining all of those fields for 'created', but I get the same problem.) I'm a bit stumped as to what I'm doing wrong - for one thing I can't see why Doctrine would be running any unsigned checks against a 'timestamp' datatype... Any help gratefully received! Alex

    I have function problem using this code (below), the embedded flash movieclip disappears or completely prevents the scrollto.js query to function in DW cs3. Communication between Flash and JavaScript is without problems, it is the call back I can't find to work and more frustratingly, should be simple, as no values are not required. So far, this has been hours of scouring the net without a workable end in sight...ahrr. What is a function for this to work?

  • JNI: Long-object created with wrong value

    - by Torbjörn Eklund
    Hi! I am writing a c-jni function in Android, and I am having problems with creating a Long-object. I have succeeded in calling the constructor, but when I read the value of the object with longValue, I get the wrong result. jmethodID longConstructor; jmethodID longGetLongValue; jclass cls; jobject obj; // Create a object of type Long. cls = (*env)->FindClass(env,"java/lang/Long"); longConstructor = (*env)->GetMethodID(env,cls,"<init>","(J)V"); obj = (*env)->NewObject(env, cls, longConstructor, 4242); // Get the value by calling the function longValue. longGetLongValue= (*env)->GetMethodID(env,cls,"longValue","()J"); long return_long_value = (*env)->CallLongMethod(env, obj, longGetLongValue); // Log the result. LOGD("%li", return_long_value); I would expect that the above code would print 4242 in the log, however the value that is printed in the log is 1691768. Does anybody have an idea on why 4242 is not written in the log?

  • Link Maven OSGi to Maven NetBeans Platform Project

    - by mxro
    I am using NetBeans 6.9 Beta and I would like to accomplish the following: Set up a project representing the main application using Maven (for instance "Maven Project", "Maven NetBeans Application") Ideally, the project should only contain the necessary libraries to run in Apache Felix (I would like to be able to right-click the project and select "Run in Felix") I do not want that the project contains all the NetBean Platform APIs I would prefer to implement the modules using OSGi. For instance "Maven OSGi Bundle", "Maven NetBeans Module" + OSGi These are the problems, which I have at the moment: The standard Maven archetype ("Maven NetBeans Application") seems always to select all APIs and I have not found a way to deselect APIs - in normal NetBeans Platform Applications that can be accomplished by going to the project properties and deselected the platform modules) - I guess it has something to do with the NetBeans repository (http://bits.netbeans.org/maven2)? Do I have to create another repository? When creating normal "NetBeans Module" with OSGi support, the modules contain both NetBeans Module and OSGi meta data, which is nice. But the "Maven NetBeans Modules" have only NetBeans meta data and the Maven OSGi Bundles have only OSGi meta data). I figured out how to add modules to the project by using project / new and then placing the modules in the Maven project folder. However, I do not quite know yet how I could link to modules from other locations (NetBeans uses Maven modules, which have to be in the same directory as the project?). Below some useful links for Maven + OSGi in NetBeans wiki.netbeans.org/STS_69_Maven_OSGI NetBeans Maven OSGi Test Specification platform.netbeans.org/tutorials/nbm-maven-quickstart.html NetBeans Platform Quick Start Using Maven (6.9) wiki.netbeans.org/MavenBestPractices NetBeans Maven BestPractices maven.apache.org/pom.html#Aggregation Maven Documentation Multi-Module Projects (sorry about the missing protocol but couldn't post the message otherwise)

  • Is there a good tutorial for figuring out what a website is doing so your program can do the same th

    - by brian d foy
    Is there a good guide or tutorial for people who need to programmatically interact with dynamic websites? There's been a rash of Perl questions about that lately, and I haven't found a good resource to point people toward. I'm asking not because I need one but because I don't want to waste my time writing it if it already exists. Although I'm most interested in Perl, the extra tools and techniques are mostly the same. Typically, I see see these problems in people's questions: Handling, setting, and saving cookies Finding and interacting with forms Handling JavaScript inside your user-agent especially things like onLoad, onSumbit, and Ajax Using HTTP sniffer tools Using Web developer plugins in interactive browsers Interacting with DOM, screen scraping, etc. If there's no good tutorial, I'll add it to my list of things to do (unless someone else wants to do it :). Along the way, if you don't have a suggestion for an existing tutorial, please suggest the things that you think should be in a new one, including links, your favorite tools, and your own user-agent development experiences. I don't care about the particular language you use.

  • TableView Cells unresponsive

    - by John Donovan
    I have a TableView and I wish to be able to press several cells one after the other and have messages appear. At the moment the cells are often unresponsive. I found some coed for a similar problem someone was kind enough to post, however, although he claimed it worked 100% it doesn't work for me. The app won't even build. Here's the code: -(UIView*) hitTest:(CGPoint)point withEvent:(UIEvent*)event { // check to see if the hit is in this table view if ([self pointInside:point withEvent:event]) { UITableViewCell* newCell = nil; // hit is in this table view, find out // which cell it is in (if any) for (UITableViewCell* aCell in self.visibleCells) { if ([aCell pointInside:[self convertPoint:point toView:aCell] withEvent:nil]) { newCell = aCell; break; } } // if it touched a different cell, tell the previous cell to resign // this gives it a chance to hide the keyboard or date picker or whatever if (newCell != activeCell) { [activeCell resignFirstResponder]; self.activeCell = newCell; // may be nil } } // return the super's hitTest result return [super hitTest:point withEvent:event]; } With this code I get this warning: that my viewController may not respond to pointsInside:withEvent (it's a TableViewController). I also get some faults: request for member 'visibleCells' in something not a structure or a union. incompatible type for argument 1 of pointInsideWithEvent, expression does not have a valid object type and similar. I must admit I'm not so good at reading other people's code but I was wondering whether the problems here are obvious and if so if anyone could give me a pointer it would be greatly appreciated.

  • JSF ISO-8859-2 charset

    - by Vladimir
    Hi! I have problem with setting proper charset on my jsf pages. I use MySql db with latin2 (ISO-8859-2 charset) and latin2_croatian_ci collation. But, I have problems with setting values on backing managed bean properties. Page directive on top of my page is: <%@ page language="java" pageEncoding="ISO-8859-2" contentType="text/html; charset=ISO-8859-2" %> In head I included: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> And my form tag is: <h:form id="entityDetails" acceptcharset="ISO-8859-2"> I've created and registered Filter in web.xml with following doFilter method implementation: public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { request.setCharacterEncoding("ISO-8859-2"); response.setCharacterEncoding("ISO-8859-2"); chain.doFilter(request, response); } But, i.e. when I set managed bean property through inputText, all special (unicode) characters are replaced with '?' character. I really don't have any other ideas how to set charset to pages to perform well. Any suggestions? Thanks in advance.

  • Is possible to reuse subqueries?

    - by Gothmog
    Hello, I'm having some problems trying to perform a query. I have two tables, one with elements information, and another one with records related with the elements of the first table. The idea is to get in the same row the element information plus several records information. Structure could be explain like this: table [ id, name ] [1, '1'], [2, '2'] table2 [ id, type, value ] [1, 1, '2009-12-02'] [1, 2, '2010-01-03'] [1, 4, '2010-01-03'] [2, 1, '2010-01-02'] [2, 2, '2010-01-02'] [2, 2, '2010-01-03'] [2, 3, '2010-01-07'] [2, 4, '2010-01-07'] And this is want I would like to achieve: result [id, name, Column1, Column2, Column3, Column4] [1, '1', '2009-12-02', '2010-01-03', , '2010-01-03'] [2, '2', '2010-01-02', '2010-01-02', '2010-01-07', '2010-01-07'] The following query gets the proper result, but it seems to me extremely inefficient, having to iterate table2 for each column. Would be possible in anyway to do a subquery and reuse it? SELECT a.id, a.name, (select min(value) from table2 t where t.id = subquery.id and t.type = 1 group by t.type) as Column1, (select min(value) from table2 t where t.id = subquery.id and t.type = 2 group by t.type) as Column2, (select min(value) from table2 t where t.id = subquery.id and t.type = 3 group by t.type) as Column3, (select min(value) from table2 t where t.id = subquery.id and t.type = 4 group by t.type) as Column4 FROM (SELECT distinct id FROM table2 t WHERE (t.type in (1, 2, 3, 4)) AND t.value between '2010-01-01' and '2010-01-07') as subquery LEFT JOIN table a ON a.id = subquery.id

  • Missing chars in JpGraph

    - by Álvaro G. Vicario
    I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?
