• Prevent Jquery Accordion tab from expanding

  - by Edwin

  I'm trying to use JQuery UI Accordion as a menu, but I can't figure out how to prevent some tabs from expanding. My JS: $("#sidebar").accordion({ collapsible: true, changestart: function(event, ui) { switch ($(ui.newHeader).attr("id")) { case "sidebar_grades": return false; break; } } }); the HTML: <div id="sidebar"> <h3 id="sidebar_home"> <a href="/blah">Home</a> </h3> <div> <a href="/child">Settings</a> </div> <h3 id="sidebar_grades"> <a href="/grades">Grades</a> </h3> <div></div> <h3 id="sidebar_calendar"> <a href="/calendar">Calendar</a> </h3> <div></div> </div> In the above example, since #sidebar_grades doesn't have any child, it should not be expandable, but user can click on the link. I tried using "changestart" event and return false when #sidebar_grades is clicked, but it doesn't work. I also tried attaching onClick event to #sidebar_grades to return false, but that didn't work either. Any idea how to do this? Thank you!

• Android - How to Use SQLiteDatabase.open?

  - by Edwin Lee

  Hi all, i'm trying to use SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS)); to create/open a database instead of making use of the SQLiteOpenHelper (because i want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, i am getting this exception for that line of code: 04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): java.lang.RuntimeException: An error occured while executing doInBackground() 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.os.AsyncTask$3.done(AsyncTask.java:200) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:234) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:258) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask.run(FutureTask.java:122) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:648) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:673) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.lang.Thread.run(Thread.java:1060) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): Caused by: android.database.sqlite.SQLiteException: unable to open database file 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.dbopen(Native Method) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.<init>(SQLiteDatabase.java:1584) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:638) ... Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am i just using SQLiteDatabase.openDatabase the wrong way?) Would it help if i create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that i passed in?) If creating the file manually is the way to go, is it just an empty file, or do i have to write something to it? Thanks and Regards.

• Use Google Calendar UI but showing only filtered events

  - by Edwin

  I have just started using Google Calendar API (using Python client). I'm basically developing a web app for a school with Django. What I'd like to achieve is something like this: To make things simple for now, I have 1 Google account and all events will be created in the calendar under that account (this is the school calendar). The calendar will be made public. When a class is created by a teacher, the class schedule will be automatically added as an event in the Google Calendar. When a student logs in, he can see the school calendar, showing only schedules from the classes that he's registered in. I think I can filter the calendar feeds to show only class schedules that a student is registered in using Google Data API. The problem is, how can I display Google Calendar on my web app using Google Calendar UI to show only those filtered events? I can use Google Calendar UI with the provided embeddable HTML snippet, but I can't control/filter events with that (i.e. all events in the school calendar will be displayed). Or perhaps I'm missing something? I read the Data API guide and the Publishing tool doc but I can't seem to find this information. THanks in advance!

• Delphi OLE - How to avoid errors like "The requested member of the collection does not exist"?

  - by Edwin

  Hi, I'm automating Word with Delphi, but some times I got an error message: The requested member of the collection does not exist It seems that the Item member of the Styles collection class does not always exist and some times causes the above mentioned error. My workaround is to catch the exception and skip it, but is there anyway to detect it instead of using the try...except block? The problem with the try...except block is that when debugging the raised exception is annoying... My code example: var aWordDoc: _WordDocument i: Integer; ovI: OleVariant; wordStyle: Style; begin for i := 1 to aWordDoc.Styles.Count do begin ovI := i; try wordStyle := aWordDoc.Styles.Item(ovI); except Continue;//skip if any error occurred. end; //do something with wordStyle end; end

• How do you use scripting language (PHP, Python, etc) to improve your productivity?

  - by Edwin

  Hi, I'm a Delphi developer on the Windows platform, recently read the PHP tutorial at W3CSchools, it looks interesting. We all know scripting languages are very good at web site development, but I also want to utilize it to improve my productivity or get some tedious tasks done quickly, maybe some quick-and-dirty string/file processing? How do you usually do with scripting languages apart from software development? And we need a responsive, decent IDE/editor in order to gain productivity when writing scripts for this purpose? Thanks for in advance!

• Why Banks or Financial Companies prefer Oracle than other RDBMS for their "Core" systems?

  - by edwin.nathaniel

  I'd like to know why most Banks or Financial companies prefer Oracle than other RDBMS for their core systems (the absolutely minimum features that a Bank must support). I found a few answers that didn't satisfy me. For example: Oracle has more features. But features for what? Can't you implement that in application level if you were not using Oracle? Could someone please describe a bit more technical but still on high-level overview of what the bank needs and how Oracle would solve it and the others can't or don't have the features yet? I came from the web-app (web 2.0) crowd who normally hear news about MySQL, PostgreSQL or even key-value/column-oriented storage solution. I have almost zero knowledge on how Banks or Financial companies operates from technical perspective. Thank you, Ed

• Is it possible to replace the system open file dialog?

  - by Edwin

  I want to replace the standard system open file dialog with the one I wrote, that means no matter within which programs you are opening a file, my dialog will be shown instead of the standard one, is this possible? It seems that that there is no such API provided to accomplish this, is it possible to use some hooking technique, but this has to be reliable and not to be treated as spyware by anti-virus tools? any other options? If this is not possible, is it possible to add to the spacebar or toolbar in the standard open file dialog a button which invokes my dialog, which allow users select a file and in turn returns the path of the selected file to the "File name" input box of the standard dialog? Any hits, links and code examples will be appreciated.

• How to use TJvBalloonWindow as the hint window for Virtual treeview?

  - by Edwin

  I have a 'hint window leftovers' problem with Virtual Treeview in an Office add-in, and now I want to customize the hint window to solve the problem. I want to use TJvBallonHint from the JVCL package, which is also used in other parts of my program. I inherited TVirtualStringTree and have overridden the GetHintWindowClass method like the following code. The TJvBallonHint window class is applied, but the hint text is not drawn. Any tips for me? Thank you! function TMyStringTree.GetHintWindowClass: THintWindowClass; begin Result :=TJvBalloonWindow;; end;

• Virtual StringTree's hint windows are left out on the screen

  - by Edwin

  Hi, See this screenshot, in the middle it's the small hint windows that are generated by a TVirtualStringTree control and were left out on the screen, these hint windows will remain there until the application exits. the problem happens when the treeview's hint is shown and the mouse leaves quickly to the window next to it. Any idea about how to avoid this or how to clear those un-erased hint windows if it's difficult to avid this? Few days ago I asked a similar question, while the hint windows in the screenshots look the same, the are not the same problem. That problem, the hint text never shows and only that kind of uncompleted hint windows are shown; This problem, the hint text shows but the hint windows are not completely erased in a case (as I described above). Hope it's clear.

• Handling data update/freshness issue in web-app in general (or GWT specifically)

  - by edwin.nathaniel

  In general, how do you guys handle user update/data freshness interaction with the user (UI issue) in web-apps? For example: Multi-users web-app (like project management) Login to a "virtual" space People can update project names, etc How to handle a situation such that: user-A and user-B load a project with title "Project StackOverflow" user-B updates the title to "Project StackExchange" user-A updates the title after user-B update operation to "Project Basecamp" The question I'm asking is from the user perspective (UI) and not about transactional operation. What do most people do in this situation? What would you do after user-B updates the title in user-A screen/view? What happened when user-A tries to update the title after user-B finished his/her update operation? do you inform user-A that the title has changed and he/she has to reload the page? do you go ahead and change the title and let user-B has old data? Do you do some sort of application-level "locking" mechanism? (if someone is updating, nobody else can?) Or fix the application workflow? (who has the access to be able to change things, etc). What would be the simplest solution, but at the same time not annoy the user with more dialog/warning messages. I've encountered this particular problem frequently in a GWT app specifically where domain models are being passed around and refreshing the whole app/client-side isn't the optimal solution in my mind (since it means the whole "loading"/initialization phase must be executed again in this specific environment). Maybe the answer is to stay away from GWT? :) Love to hear options, solutions, and advises from you guys. Thanks

• Any really modern, good-looking desktop apps that are developed with PyQt/PySide?

  - by Edwin

  Hi, I have started using Python for web development recently, it's kinda cool; I have seen programs that are developed in QT/C++, which is good enough in terms of esthetics; I have just noticed the new PySide project (which brings LGPL Qt license to Python and it doesn't support Windows yet). In view of the above, I see the possibility of using Python + PyQt/PySide to develop cross platform apps in the future :) but I have several doubts right now: Can PyQty/PySide be used to develop really complex/modern UI? Can somebody give me some points to have a look at some nice-looking screenshots of apps that are developed in Python+QT? What about the performance? Thanks in advance!
