  • HTML5 Video Element on iPad doesn't fire onclick?

    - by bhups
    I am using the video element in my HTML as following:<div id="container" style="background:black; overflow:hidden;width:320px;height:240px" <video style="background:black;display:block" id="vdo" height="240px" width="320px" src="http://mydomain/vid.mp4"</video</div And in javascript I am doing this:var video=document.getElementById('vdo'); var container=document.getElementById('container'); video.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); container.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); On desktop safari/chrome everything is working fine. I can see two "clicked" in the console. But on ipad there is nothing. First I tried with iOS versin 3.2, then I updated it to the latest one 4.2.1 without any success.I found a similar question HTML5 Video Element on iPad doesn't fire onclick or touchstart events? where it suggests not to use controls in video tag and I am not using it.

  • Spring Dependency Injecting an annotated Aspect

    Using Spring I've had some issues with doing a dependency injection on an annotated Aspect class. CacheService is injected upon the Spring context's startup, but when the weaving takes place, it says that the cacheService is null. So I am forced to relook up the spring context manually and get the bean from there. Is there another way of going about it? Here is an example of my Aspect: import org.apache.log4j.Logger; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import com.mzgubin.application.cache.CacheService; @Aspect public class CachingAdvice { private static Logger log = Logger.getLogger(CachingAdvice.class); private CacheService cacheService; @Around("execution(public *com.mzgubin.application.callMethod(..)) &&" + "args(params)") public Object addCachingToCreateXMLFromSite(ProceedingJoinPoint pjp, InterestingParams params) throws Throwable { log.debug("Weaving a method call to see if we should return something from the cache or create it from scratch by letting control flow move on"); Object result = null; if (getCacheService().objectExists(params))}{ result = getCacheService().getObject(params); } else { result = pjp.proceed(pjp.getArgs()); getCacheService().storeObject(params, result); } return result; } public CacheService getCacheService(){ return cacheService; } public void setCacheService(CacheService cacheService){ this.cacheService = cacheService; } }

  • Updating a field in a record dyanamically in extjs

    - by Daemon
    Scenario I want to update the column data of particular record in grid having store with static data. Here is my store: : : extend : 'Ext.data.Store', model : 'MyModel', autoLoad:true, proxy: { type: 'ajax', url:'app/data/data.json', reader: { type: 'json', root: 'users' } }, My data.json { 'users': [ { QMgrStatus:"active", QMgrName: 'R01QN00_LQYV', ChannelStatus:'active', ChannelName : 'LQYV.L.CLNT', MxConn: 50 } ] } What I am doing to update the record : var grid = Ext.getCmp('MyGrid'); var store = Ext.getStore('Mystore'); store.each(function(record,idx){ val = record.get('ChannelName'); if(val == "LQYV.L.CLNT"){ record.set('ChannelStatus','inactive'); record.commit(); } }); console.log(store); grid.getView().refresh(); MY PROBLEM I am getting the record updated over here.It is not getting reflected in my grid panel.The grid is using the same old store(static).Is the problem of static data? Or am I missing something or going somewhere wrong? Please help me out with this issue.Thanks a lot. MY EDIT I am tryng to color code the column based on the status.But here I am always getting the status="active" even though I am updating the store. What I am trying to do in my grid { xtype : 'grid', itemId : 'InterfaceQueueGrid', id :'MyGrid', store : 'Mytore', height : 216, width : 600, columns : [ { text: 'QueueMgr Status', dataIndex: 'QMgrStatus' , width:80 }, { text: 'Queue Manager \n Name', dataIndex: 'QMgrName' , width: 138}, { text: 'Channel Status',dataIndex: 'ChannelStatus' , width: 78,align:'center', renderer: function(value, meta, record) { var val = record.get('ChannelStatus'); console.log(val); // Here I am always getting status="active". if (val == 'inactive') { return '<img src="redIcon.png"/>'; }else if (val == 'active') { return '<img src="greenIcon.png"/>'; } } }, { text: 'Channel Name', align:'center', dataIndex: 'ChannelName', width: 80} { text: 'Max Connections', align:'center', dataIndex: 'MxConn', width: 80} ] }

  • jQuery Ajax loads URL multiple times, how do I unbind/rebind properly?

    - by gmoz22
    I load a SELECT element via Ajax (list of brands), get its selected value (brand id) and load another SELECT via another Ajax URL (list of templates for currently selected brand). Here's my code: $(document).ready( function() { // DO NOT cache Ajax calls $.ajaxSetup ({ cache: false }); // loader var ajax_load = "Loading..."; // Brands List URL var loadBrandUrl = "getBrandsList.php"; // Templates List URL var loadTemplateUrl = "getTemplatesList.php"; $("#brandslistSelect").html(ajax_load).load(loadBrandUrl) .ajaxComplete(function(){ // Brands select loaded /* Load Templates SELECT the first time since no .change() has happened */ var selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value console.log(selectedBrand); // Log selected brand to console // get Templates select, commented for now since it does an infinite loop // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); /* End initial load template */ /* On interaction with the Brands SELECT */ $("#brandslistSelect").change(function () { // on interaction with select selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value // get Templates SELECT $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ) }); /* End interaction with the Brands SELECT */ }); }); It returns selectedBrand in the console 3 times : selectedBrand = undefined selectedBrand = undefined selectedBrand = 101 Now, if I uncomment the following line, same output as above but it also loads the templates URL indefinitely : // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); Any idea how I could modify this code to make it work as intended? Thanks for your help stackOverflow community!

  • Facebook Android SDK. Error validating access token

    - by Mj1992
    I am trying to access user information from facebook sdk.But I keep getting this error. {"error":{"message":"Error validating access token: The session has been invalidated because the user has changed the password.","type":"OAuthException","code":190,"error_subcode":460}} Here is the call which returns me the error in the response parameter of the oncomplete function. mAsyncRunner.request("me", new RequestListener() { @Override public void onComplete(String response, Object state) { Log.d("Profile", response); String json = response; //<-- error in response try { JSONObject profile = new JSONObject(json); MainActivity.this.userid = profile.getString("id"); new GetUserProfilePic().execute(); runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(getApplicationContext(), "Name: " + MainActivity.this.userid, Toast.LENGTH_LONG).show(); } }); } catch (JSONException e) { e.printStackTrace(); Log.e("jsonexception",e.getMessage()); facebook.extendAccessTokenIfNeeded(MainActivity.this, null); GetUserInfo(); } } @Override public void onIOException(IOException e, Object state) { } @Override public void onFileNotFoundException(FileNotFoundException e, Object state) { } @Override public void onMalformedURLException(MalformedURLException e, Object state) { } @Override public void onFacebookError(FacebookError e, Object state) { } }); Sometimes I get the correct response also.I think this is due to the access token expiration if I am right. So can you guys tell me how to extend the access token although I've used this facebook.extendAccessTokenIfNeeded(this, null); in the onResume method of the activity. How to solve this?

  • Efficient Multiplication of Varying-Length #s [Conceptual]

    - by Milan Patel
    Write the pseudocode of an algorithm that takes in two arbitrary length numbers (provided as strings), and computes the product of these numbers. Use an efficient procedure for multiplication of large numbers of arbitrary length. Analyze the efficiency of your algorithm. I decided to take the (semi) easy way out and use the Russian Peasant Algorithm. It works like this: a * b = a/2 * 2b if a is even a * b = (a-1)/2 * 2b + a if a is odd My pseudocode is: rpa(x, y){ if x is 1 return y if x is even return rpa(x/2, 2y) if x is odd return rpa((x-1)/2, 2y) + y } I have 3 questions: Is this efficient for arbitrary length numbers? I implemented it in C and tried varying length numbers. The run-time in was near-instant in all cases so it's hard to tell empirically... Can I apply the Master's Theorem to understand the complexity...? a = # subproblems in recursion = 1 (max 1 recursive call across all states) n / b = size of each subproblem = n / 1 - b = 1 (problem doesn't change size...?) f(n^d) = work done outside recursive calls = 1 - d = 0 (the addition when a is odd) a = 1, b^d = 1, a = b^d - complexity is in n^d*log(n) = log(n) this makes sense logically since we are halving the problem at each step, right? What might my professor mean by providing arbitrary length numbers "as strings". Why do that? Many thanks in advance

  • How to use clearInterval() and then make changes to the DOM?

    - by George D.
    I have this code and the problem I have is that I want to stop the loop and then replace the text 'Done!' that comes from the sms-loader.php script with the "textnew" string. Problem is that the loop occurs one more time so the text in the div.checkstatus field is again replaced by the calling php script. The strange thing is that I see the log message and again I get a new (and final) request, although the ordering is the opposite (first stop then replace text()) in my script. I need to understand why this is happening. $(document).ready(function() { var interval = ""; $('.checkstatus').each(function(){ var msgid = $(this).data('msg') $this = $(this), hid = $this.data('history'), textnew = '<a href="sms-dstatus.php?id='+msgid+'&sid=' +hid+ '&amp;keepThis=true&amp;TB_iframe=true&amp;height=430&amp;width=770" title="Delivery Status" class="thickbox"><img src="../template/icons/supermini/chart_curve.png" alt="status" width="16" height="16" /></a>'; interval = setInterval(function() { $this.load('../pages/sms-loader.php?id='+msgid); // stop the loop if($this.text()=='Done!'){ // stop it clearInterval(interval); console.log(textnew); this.html(textnew); /// this line is the problem } }, 5000); // 5 secs }); });

  • OnClickListener on Tabs not working

    - by Aracos
    Greetings, I am trying to get the Click - event when clicking on the currently selected tab of my TabActivity. The onTabChangedHandler is only called whenever the tab is changed, not if the currently active Tab is clicked. The debugger tells me i have the onClickListener Registered for the TabWidget within my TabHost. Am i registering for the wrong View? Also, I am unable to create a Context Menu for the Tabs, only for its content, is this problem related? public class TestDroidViewTab extends TabActivity implements TabContentFactory , OnTabChangeListener, OnClickListener { private static final String LOG_KEY = "TEST"; ListView listView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); TabHost.TabSpec ts = tabHost.newTabSpec("ID_1"); ts.setIndicator("1"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_2"); ts.setIndicator("2"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_3"); ts.setIndicator("3"); ts.setContent(this); tabHost.addTab(ts); tabHost.setOnClickListener(this); tabHost.setOnTabChangedListener(this); } public void onClick(View v) { Log.d(LOG_KEY, "OnClick"); } public void onTabChanged(String tabId) { Log.d(LOG_KEY, "OnTabChanged"); }

  • A minimalistic smart array (container) class template

    - by legends2k
    I've written a (array) container class template (lets call it smart array) for using it in the BREW platform (which doesn't allow many C++ constructs like STD library, exceptions, etc. It has a very minimal C++ runtime support); while writing this my friend said that something like this already exists in Boost called MultiArray, I tried it but the ARM compiler (RVCT) cries with 100s of errors. I've not seen Boost.MultiArray's source, I've started learning templates only lately; template meta programming interests me a lot, although am not sure if this is strictly one that can be categorized thus. So I want all my fellow C++ aficionados to review it ~ point out flaws, potential bugs, suggestions, optimizations, etc.; something like "you've not written your own Big Three which might lead to...". Possibly any criticism that will help me improve this class and thereby my C++ skills. Edit: I've used std::vector since it's easily understood, later it will be replaced by a custom written vector class template made to work in the BREW platform. Also C++0x related syntax like static_assert will also be removed in the final code. smart_array.h #include <vector> #include <cassert> #include <cstdarg> using std::vector; template <typename T, size_t N> class smart_array { vector < smart_array<T, N - 1> > vec; public: explicit smart_array(vector <size_t> &dimensions) { assert(N == dimensions.size()); vector <size_t>::iterator it = ++dimensions.begin(); vector <size_t> dimensions_remaining(it, dimensions.end()); smart_array <T, N - 1> temp_smart_array(dimensions_remaining); vec.assign(dimensions[0], temp_smart_array); } explicit smart_array(size_t dimension_1 = 1, ...) { static_assert(N > 0, "Error: smart_array expects 1 or more dimension(s)"); assert(dimension_1 > 1); va_list dim_list; vector <size_t> dimensions_remaining(N - 1); va_start(dim_list, dimension_1); for(size_t i = 0; i < N - 1; ++i) { size_t dimension_n = va_arg(dim_list, size_t); assert(dimension_n > 0); dimensions_remaining[i] = dimension_n; } va_end(dim_list); smart_array <T, N - 1> temp_smart_array(dimensions_remaining); vec.assign(dimension_1, temp_smart_array); } smart_array<T, N - 1>& operator[](size_t index) { assert(index < vec.size() && index >= 0); return vec[index]; } size_t length() const { return vec.size(); } }; template<typename T> class smart_array<T, 1> { vector <T> vec; public: explicit smart_array(vector <size_t> &dimension) : vec(dimension[0]) { assert(dimension[0] > 0); } explicit smart_array(size_t dimension_1 = 1) : vec(dimension_1) { assert(dimension_1 > 0); } T& operator[](size_t index) { assert(index < vec.size() && index >= 0); return vec[index]; } size_t length() { return vec.size(); } }; Sample Usage: #include "smart_array.h" #include <iostream> using std::cout; using std::endl; int main() { // testing 1 dimension smart_array <int, 1> x(3); x[0] = 0, x[1] = 1, x[2] = 2; cout << "x.length(): " << x.length() << endl; // testing 2 dimensions smart_array <float, 2> y(2, 3); y[0][0] = y[0][1] = y[0][2] = 0; y[1][0] = y[1][1] = y[1][2] = 1; cout << "y.length(): " << y.length() << endl; cout << "y[0].length(): " << y[0].length() << endl; // testing 3 dimensions smart_array <char, 3> z(2, 4, 5); cout << "z.length(): " << z.length() << endl; cout << "z[0].length(): " << z[0].length() << endl; cout << "z[0][0].length(): " << z[0][0].length() << endl; z[0][0][4] = 'c'; cout << z[0][0][4] << endl; // testing 4 dimensions smart_array <bool, 4> r(2, 3, 4, 5); cout << "z.length(): " << r.length() << endl; cout << "z[0].length(): " << r[0].length() << endl; cout << "z[0][0].length(): " << r[0][0].length() << endl; cout << "z[0][0][0].length(): " << r[0][0][0].length() << endl; // testing copy constructor smart_array <float, 2> copy_y(y); cout << "copy_y.length(): " << copy_y.length() << endl; cout << "copy_x[0].length(): " << copy_y[0].length() << endl; cout << copy_y[0][0] << "\t" << copy_y[1][0] << "\t" << copy_y[0][1] << "\t" << copy_y[1][1] << "\t" << copy_y[0][2] << "\t" << copy_y[1][2] << endl; return 0; }

  • Asp.Net 2 integrated sites How to Logout second site programatically.

    - by NBrowne
    Hi , I am working with an asp.net 2.0 site (call it site 1) which has an iframe in it which loads up another site (site2) which is also an asp.net site which is developed by our team. When you log onto site 1 then behind the scenes site 2 is also logged in so that when you click the iframe tab then this displays site 2 with the user logged in (to prevent the user from having to log in twice). The problem i have is that when a user logs out of site 1 then we call some cleanup methods to perform FormsAuthentication.SignOut and clean session variables etc but at the moment no cleanup is called when the user on site 2. So the issue is that if the user opens up Site 2 from within a browser then website 2 opens with the user still logged in which is undesired. Can anyone give me some guidance as to the best approach for this?? One possible approach i though of was just that on click of logout button i could do a call to a custom page on Site 2 which would do the logout. Code below HttpWebRequest request; request = ((HttpWebRequest)(WebRequest.Create("www.mywebsite.com/Site2Logout.aspx"))); request.Method = "POST"; HttpCookie cookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName]; Cookie authenticationCookie = new Cookie( FormsAuthentication.FormsCookieName, cookie.Value, cookie.Path, HttpContext.Current.Request.Url.Authority); request .CookieContainer = new CookieContainer(); request .CookieContainer.Add(authenticationCookie); response.GetResponse(); Problem i am having with this code is that when i run it and debug on Site 2 and check to see if the user is Authenticated they are not which i dont understand because if i open browser and browse to Site 2 i am Still authenticated. Any ideas , different direction to take etc ??? Please let me know if you need any more info or if i something i have said dosent make sense. Thanks

  • Python logging in Django

    - by Jeff
    I'm developing a Django app, and I'm trying to use Python's logging module for error/trace logging. Ideally I'd like to have different loggers configured for different areas of the site. So far I've got all of this working, but one thing has me scratching my head. I have the root logger going to sys.stderr, and I have configured another logger to write to a file. This is in my settings.py file: sviewlog = logging.getLogger('MyApp.views.scans') view_log_handler = logging.FileHandler('C:\\MyApp\\logs\\scan_log.log') view_log_handler.setLevel(logging.INFO) view_log_handler.setFormatter(logging.Formatter('%(asctime)s %(name)-12s %(levelname)-8s %(message)s')) sviewlog.addHandler(view_log_handler) Seems pretty simple. Here's the problem, though: whatever I write to the sviewlog gets written to the log file twice. The root logger only prints it once. It's like addHandler() is being called twice. And when I put my code through a debugger, this is exactly what I see. The code in settings.py is getting executed twice, so two FileHandlers are created and added to the same logger instance. But why? And how do I get around this? Can anyone tell me what's going on here? I've tried moving the sviewlog logger/handler instantiation code to the file where it's used (since that actually seems like the appropriate place to me), but I have the same problem there. Most of the examples I've seen online use only the root logger, and I'd prefer to have multiple loggers.

  • Can this line of code really throw an IndexOutOfRange exception?

    - by Jonathan M
    I am getting an IndexOutOfRange exception on the following line of code: var searchLastCriteria = (SearchCriteria)Session.GetSafely(WebConstants.KeyNames.SEARCH_LAST_CRITERIA); I'll explain the above here: SearchCriteria is an Enum with only two values Session is the HttpSessionState GetSafely is an extension method that looks like this: public static object GetSafely(this HttpSessionState source, string key) { try { return source[key]; } catch (Exception exc) { log.Info(exc); return null; } } WebConstants.KeyNames.SEARCH_LAST_CRITERIA is simply a constant I've tried everything to replicate this error, but I cannot reproduce it. I am beginning to think the stack trace is wrong. I thought perhaps the exception was actually coming from the GetSafely call, but it is swallowing the exceptions, so that can't be the case, and even if it was, it should show up in the stack trace. Is there anything in the line of code above that could possible throw an IndexOutOfRange exception? I know the line will throw an NullReferenceException if GetSafely returns null, and it will also throw an InvalidCastException if it returns anything that cannot be cast to SearchCriteria, but an IndexOutOfRange exception? I'm scratching my head here. Here is the stack trace: $LOG--> 2010-06-11 07:01:33,814 [ERROR] SERVERA (14) Web.Global - Index was outside the bounds of the array.

  • JQuery: Combine multiple pages into one

    - by k_wave
    I am developing an application by using phonegap and jQuery Mobile. Phonegap recommends a single document structure. As 5 divs or more in a document are pretty unclear, I'm trying to split up my pages (the div's) into multiple documents. As soon as phonegap loads the app, I want to insert these documents into the index.html. function loadPage(external_document) { var docname=external_document+".html"; $.get(docname, function(data) { console.log(docname+" loading"); $("body").append($(data).find("body")); $("head").append($(data).find("head")); console.log(docname+" loaded"); }); } document.addEventListener("deviceready", function(){ loadPage("DialogCredentials"); }, false); DialogCredentials.html <html> <head> <script type="text/javascript" src="js/DialogCredentials.js"></script> </head> <body> <div data-role="page" id="dlg_credentials"> <div data-role="header"><h1>Login</h1></div> <div data-role="content"> ... </div> </div><!-- /page --> </body> </html> As soon as the loadPage gets executed there should be a <div id="dlg_credentials"… and the corresponding javascript tag in the dom of my main document. But it isn't. There are no errors shown in the web inspector. So what am I doing wrong here?

  • Is it possible to create a null function that will not produce warnings?

    - by bbazso
    I have a logger in a c++ application that uses defines as follows: #define FINEST(...) Logger::Log(FINEST, _FILE, __LINE, __func, __VA_ARGS_) However what I would like to do is to be able to switch off these logs since they have a serious performance impact on my system. And, it's not sufficient to simply have my Logger not write to the system log. I really need to get rid of the code produced by the logs. In order to do this, I changed the define to: #define FINEST(...) Which works, but this produces a whole bunch of warning in my code since variables are unused now. So what I would like to have is a sort of NULL FUNCTION that would not actually exist, but would not produce warnings for the unused variables. So, said another way, I would like it to compile with no warnings (i.e. the compiler thinks that the variables are used for a function) but the function does not actually exist in the application (i.e. produces no performance hit). Is this possible? Thanks!

  • Exceptions over remote methods

    - by Andrei Vajna II
    What are the best practices for exceptions over remote methods? I'm sure that you need to handle all exceptions at the level of a remote method implementation, because you need to log it on the server side. But what should you do afterwards? Should you wrap the exception in a RemoteException (java) and throw it to the client? This would mean that the client would have to import all exceptions that could be thrown. Would it be better to throw a new custom exception with fewer details? Because the client won't need to know all the details of what went wrong. What should you log on the client? I've even heard of using return codes(for efficiency maybe?) to tell the caller about what happened. The important thing to keep in mind, is that the client must be informed of what went wrong. A generic answer of "Something failed" or no notification at all is unacceptable. And what about runtime (unchecked) exceptions?

    I want to check a svn url and to get the latest revision, then checkout it, I don't want to use HEAD because I will compare the latest revision to others. so I use "svn info" to get the "Last Changed Rev" for the url like this: D:\Project>svn info svn://.../branches/.../path Path: ... URL: svn://.../branches/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2400 Node Kind: directory Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 but, I found the 2396 revision is not checkout-able, because this path is in a branch copied from trunk, and the 2396 is the revision modified in the trunk. so when I use svn checkout -r 2396, I will get a workcopy for the path in the trunk, then I can not do checkin for the branch. D:\Project>svn checkout svn://.../branches/.../path -r 2396 workcopy ..... ..... D:\Project>svn info workcopy Path: workcopy URL: svn://.../trunk/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2396 Node Kind: directory Schedule: normal Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 So, my question is how to get a checkout-able revision for the branch path, for this example, I want to get 2397 (because 2397 is the revision which copy occur). And I know "svn log" can get the info, but "svn log" output maybe very long and parse it will be difficult than "svn info". I just want know which revision is the latest checkout-able revision for the path.

    I'm building a phonehap application. I'm using an web sql and everything works fine till data retival. function getItemGroups(){ var items_groups = new Array(); var db = window.openDatabase("merbokDB", "1.0", "MerbokDB", 5232394); db.transaction( function(tx){ tx.executeSql('SELECT * FROM item_groups',[], function(tx,result){ if(result.rows.length > 0){ var len = result.rows.length; for (var i=0; i<len; i++){ items_groups.push(result.rows.item(i).item_group); } console.log(items_groups.join()); } } ,errorCB); }, errorCB); return items_groups; } var myproducts = getItemGroups(); My problem was when I run the code "myproducts" variable is blank. but the I can see console.log(items_groups.join()); following line printing the values in console.

  • Are these hardwares compatible?

    - by Tom Kaufmann
    I am trying to upgrade my new machine but I want to do it myself. This is my 1st attempt at building system. After carefully reading reviewing feedback and my budget I have decided to select the below listed components. Can anybody let me know are they compatible or not? Transcend 64 GB 2.5" SATA Solid State Drive Asus GeForce GTX550 1GB DDR5 ENGTX550 TI DI/1GD5 Graphics Card Seagate Barracuda 1 TB HDD Internal Hard Drive Cooler Master eXtreme Power Pro 600 Power Supply Intel Core i5 2500K Sandy Bridge 3.30 GHz 95 W 4 Core Desktop Processor Intel DX79TO Motherboard Corsair CMZ8GX3M2A1600C9 8 GB DDR3 SDRAM 1600 MHz Dual Channel Kit Desktop Memory Sony AD-7260S-ZS Internal DVD Writer - Black Cooler Master Hyper TX3 EVO Intel CPU Cooler Cooler Master Elite 335U Cabinet LG E2051T 20.1 Inch SuperSlim Monitor Is any of these hardware components incompatible with I5 2500K? If you have any other suggestions for selecting any other harwdware that can boost up my performance or lower my cost while having the same performance, please suggest. But my primary questions is whether they are compatible or not! Any help is appreciated. Thank you.

  • Problems with my JS array undefined x 7

    - by Dave
    I have an array im trying to loop through to create a new type of array specific to my current page. My array looks like this: //$_SESSION['data'] = Array ( [0] => 1 [1] => 0 [2] => Tom [8] => 1 [4] => 1 [5] => Array ( [7] => Array ( [0] => Andrew [1] => 1 [2] => 1 [4] => 0 [5] => avatar.jpg [6] => 1 ) ) [6] => Array ( [0] => 1 [1] => 2 ) ) So in my JS file i have this: var stats = <? echo $_SESSION['data'][5]); ?> ; //this is the array my_data = new Array(); for(var key in stats){ if(key in my_data){} else { //prevent double entry my_data[key] = new Array(); my_data[key][0] = stats[key][6]; my_data[key][1] = stats[key][5]; my_data[key][2] = stats[key][2]; my_data[key][3] = stats[key][0]; } } console.log(my_data); Now in console.log i get this : [undefined × 7, Array[4] 0: "1" 1: "avatar.jpg" 2: "1" 3: "Andrew" length: 4 __proto__: Array[0] ] I'm wondering why it is saying undefined x7?

  • Prompting for authentication from a wxPython program and passing it along to IIS?

    - by MetaHyperBolic
    I have a client (written in Python, with a wxPython front end in dead-simple wizard style) which communicates a website running IIS. A python script receives requests and does the usual client-server dance. I would have written this as a browser application, but for the requirement that certain things happen on the local PC that the web can't help with (file manipulation, interfacing with certain USB hardware, etc.) Right now, I am simply using the logon credentials, compounded as a string from os.environ['USERDOMAIN'] and os.environ['USERNAME'], to pass along to the server, which connects to Active Directory and enumerates the members of the group, looking for those logon credentials. It's an ugly hack, but it works. Obviously, I could make people log out of the generic helper accounts and log back into Windows using specific accounts. However, I wondered how feasible it would be to provide some kind of logon prompt wherein the user can type in a name and password, then some kind of authorization token could be passed on to IIS. This seems like something I would not want to do myself, given that amateurs almost always make huge security mistakes. Now you can see why I am wishing this was purely web-based. What's a good way to handle this?

  • How should I lock the table in this VB6 / Access application?

    - by Brian Hooper
    I'm working on a VB6 application using an Access database. The application writes messages to a log table from time to time. Several instances of the application may be running simultaneously and to distinguish them they each have their own run number. The run number is deduced from the log table thus... Set record_set = New ADODB.Recordset query_string = "SELECT MAX(RUN_NUMBER) + 1 AS NEW_RUN_NUMBER FROM ERROR_LOG" record_set.CursorLocation = adUseClient record_set.Open query_string, database_connection, adOpenStatic, , adCmdText record_set.MoveLast If IsNull(record_set.Fields("NEW_RUN_NUMBER")) Then run_number = 0 Else run_number = record_set.Fields("NEW_RUN_NUMBER") End If command_string = "INSERT INTO ERROR_LOG (RUN_NUMBER, SEVERITY, MESSAGE) " & _ " VALUES (" & Str$(run_number) & ", " & _ " " & Str$(SEVERITY_INFORMATION) & ", " & _ " 'Run Started'); " database_connection.Execute command_string Obviously there is a small gap between the calculation of the run number and the appearance of the new row in the database, and to prevent another instance getting access between the two operations I'd like to lock the table; something along the lines of SET TRANSACTION READ WRITE RESERVING ERROR_LOG FOR PROTECTED WRITE; How should I go about doing this? Would locking the recordset do any good (the row in the record set doesn't match any particular row in the database)?

  • Extra NotifyIcon shown in system tray

    - by Kettch19
    I'm having an issue with an app where my NotifyIcon displays an extra icon. The steps to reproduce it are easy, but the problem is that the extra icon shows up after any of the actual codebehind we've added fires. Put simply, clicking a button triggers execution of method FooBar() which runs all the way through fine but its primary duty is to fire a backgroundworker to log into another of our apps. It only appears if this particular button is clicked. Strangely enough, we have a WndProc method override and if I step through until the extra NotifyIcon appears, it always appears during this method so something else beyond the codebehind must be triggering the behavior. Our WndProc method is currently (although I don't think it's caused by the WndProc): Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) 'Check for WM_COPYDATA message from other app or drag/drop action and handle message If m.Msg = NativeMethods.WM_COPYDATA Then ' get the standard message structure from lparam Dim CD As NativeMethods.COPYDATASTRUCT = m.GetLParam(GetType(NativeMethods.COPYDATASTRUCT)) 'setup byte array Dim B(CD.cbData) As Byte 'copy data from memory into array Runtime.InteropServices.Marshal.Copy(New IntPtr(CD.lpData), B, 0, CD.cbData) 'Get message as string and process ProcessWMCopyData(System.Text.Encoding.Default.GetString(B)) 'empty array Erase B 'set message result to 'true', meaning message handled m.Result = New IntPtr(1) End If 'pass on result and all messages not handled by this app MyBase.WndProc(m) End Sub The only place in the code where the NotifyIcon in question is manipulated at all is in the following event handler (again, don't think this is the culprit, but just for more info): Private Sub TrayIcon_MouseDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TrayIcon.MouseDoubleClick If Me.Visible Then Me.Hide() Else PositionBottomRight() Me.Show() End If End Sub The backgroundworker's DoWork is as follows (just a class call to log in to our other app, but again just for info): Private Sub LoginBackgroundWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles LoginBackgroundWorker.DoWork Settings.IsLoggedIn = _wdService.LogOn(Settings.UserName, Settings.Password) End Sub Does anyone else have ideas on what might be causing this or how to possibly further debug this? I've been banging my head on this without seeing a pattern so another set of eyes would be extremely appreciated. :) I've posted this on MSDN winforms forums as well and have had no luck there so far either.
