• Passing complex objects to javascript via IScriptControl

  - by Jeff Dege

  I'm playing around with a asp.net page that's using the IScriptControl interface to pass data from the code-behind to the custom javascript object running on the browser. I'm passing a number of properties via IScriptControl.GetScriptDescriptors(), and they're all working fine, except for one. That one is a class derived from System.Collections.Generic.Dictionary<. And even that one has been working for me, so long as the elements in the collection were scalars - ints, doubles, and strings. But when I tried to pass a member of a class, it showed up as a null object in the javascript. The class in question is marked [Serializable]. I changed it to a struct, and got the same behavior. It looks as if the serializer used in IScriptControl does a shallow copy. I need a deep copy. Any ideas?

• Adobe Plugin in Firefox showing grey screen; something to do with range requests on Apache?

  - by Sam Minnée

  I have a web page with a link to a PDF file (target="_blank"). If I click the link, the PDF reader just shows a grey screen within the Firefox browser. If I copy that link and manually open it in a new tab, the PDF will display correctly, and subsequent requests made by clicking the original link now work, suggesting that the problem occurs when loading the file into the cache. It appears as though the Adobe PDF reader plugin is making byte-range requests (I see lots of 206 responses) and I suspect that this may be the cause of the issue. I am running an Apache webserver. Has anyone had problems with Apache and Adobe's byte-range requests? Are there any workarounds?

• Storing simulation results in a persistent manner for Python?

  - by Az

  Background: I'm running multiple simuations on a set of data. For each session, I'm allocating projects to students. The difference between each session is that I'm randomising the order of the students such that all the students get a shot at being assigned a project they want. I was writing out some of the allocations in a spreadsheet (i.e. Excel) and it basically looked like this (tiny snapshot, actual table extends to a few thousand sessions, roughly 100 students). | | Session 1 | Session 2 | Session 3 | |----------|-----------|-----------|-----------| |Stu1 |Proj_AA |Proj_AB |Proj_AB | |----------|-----------|-----------|-----------| |Stu2 |Proj_AB |Proj_AA |Proj_AC | |----------|-----------|-----------|-----------| |Stu3 |Proj_AC |Proj_AC |Proj_AA | |----------|-----------|-----------|-----------| Now, the code that deals with the allocation currently stores a session in an object. The next time the allocation is run, the object is over-written. Thus what I'd really like to do is to store all the allocation results. This is important since I later need to derive from the data, information such as: which project Stu1 got assigned to the most or perhaps how popular Proj_AC was (how many times it was assigned / number of sessions). Question(s): What methods can I possibly use to basically store such session information persistently? Basically, each session output needs to add itself to the repository after ending and before beginning the next allocation cycle. One solution that was suggested by a friend was mapping these results to a relational database using SQLAlchemy. I kind of like the idea since this does give me an opportunity to delve into databases. Now the database structure I was recommended was: |----------|-----------|-----------| |Session |Student |Project | |----------|-----------|-----------| |1 |Stu1 |Proj_AA | |----------|-----------|-----------| |1 |Stu2 |Proj_AB | |----------|-----------|-----------| |1 |Stu3 |Proj_AC | |----------|-----------|-----------| |2 |Stu1 |Proj_AB | |----------|-----------|-----------| |2 |Stu2 |Proj_AA | |----------|-----------|-----------| |2 |Stu3 |Proj_AC | |----------|-----------|-----------| |3 |Stu1 |Proj_AB | |----------|-----------|-----------| |3 |Stu2 |Proj_AC | |----------|-----------|-----------| |3 |Stu3 |Proj_AA | |----------|-----------|-----------| Here, it was suggested that I make the Session and Student columns a composite key. That way I can access a specific record for a particular student for a particular session. Or I can merely get the entire allocation run for a particular session. Questions: Is the idea a good one? How does one implement and query a composite key using SQLAlchemy? What happens to the database if a particular student is not assigned a project (happens if all projects that he wants are taken)? In the code, if a student is not assigned a project, instead of a proj_id he simply gets None for that field/object. I apologise for asking multiple questions but since these are closely-related, I thought I'd ask them in the same space.

• Page Lifecycle - Using FindControl to reference a control created programatically during page load

  - by Jay Wilde

  Hi, I'm creating some text boxes on my form programatically which I need to reference later using FindControl. I've put the FindControl instruction in the page load method after the code which creates them but get an error: "Object reference not set to an instance of an object." I assume this is because the textbox controls are not created until later in the lifecycle and therefore cannot be referenced from within Page_Load. Can someone advise where in my code-behind I would need to place the FindControl instruction so that it can find these programatically created text boxes?

• Firefox 4 is displaying all text as "bold"

  - by Mateo

  I installed Firefox 4 this morning excited to checkout some of the new HTML 5 features that have been implemented and found that all text was displayed in a bold font. Here is the comparison with what Firefox 4 is displaying on my machine and Chrome. It is getting really annoying. So far I've... Emptied the cache/history/etc. Re-installed the various core fonts (Arial, Courier, Times New Roman, etc.) Checked the font defaults in FF4. The interesting part to me is that I had FF3.6x on this machine with no problems whatsoever and now this. Any ideas? System Description Windows 7 (x64) Update I just found out that this is happening in IE9 (final) as well. Must be something with the system fonts. Like I said before, this wasn't happening pre-FF4.

• Java 6.0 Virtual Machine re-caches application on every load

  - by David Neale

  I have a Java application which is loaded and cached by the JRE and for most users it only needs to cache once unless the application software has changed. However, I have one computer that caches the entire application every time they load it. It is not the version of the JRE, I have that running on other machines. It also works on this machine if logged in as a local admin, just not as a standard user. Does anybody have any ideas on what might be causing this?

• Global Timer in Javascript with Multiple Callbacks

  - by Mike Beepo

  I want to create a global timer object in javascript and then be able to add callbacks to it on the fly. This way I can just use one global timer in my script to execute all actions at a certain interval rather than wasting resources by using multiples. This is how I want to be able to piece things together: var timer = new function() { clearInterval( this.interval ); //[1] At this point I want the Callbacks to be run var self = this; setTimeout(function() {self.timer()}, 200); } function otherObject = new function() { //When created I want to bind my object's function called cb to the global timer at [1] } otherObject.prototype.cb = function() { //Stuff that should be done every time the timer is run } var someObject = new otherObject(); How would I make it possible bind any number functions (most of which are functions within other objects) to run at the interval of my timer on the fly?

• Using wget to download pdf files from a site that requires cookies to be set

  - by matt74tm

  I want to access a newspaper site and then download their epaper copies (in PDF). The site requires me to login using my email address and password and then it permits me to access those PDF URLs. I'm having trouble 'setting my session' in wget. When I login into the site from my browser, it sets two cookie values: [email protected] Password=12345 I tried: wget --post-data "[email protected]&Password=12345" http://epaper.abc.com/login.aspx However, that just downloaded the login page and saved it locally The FORM on the login page has two fields: txtUserID txtPassword and radiobuttons like this: <input id="rbtnManchester" type="radio" checked="checked" name="txtpub" value="44"> Another button: <input id="rbtnLondon" type="radio" name="txtpub" value="64"> If I post this to the login.aspx page, I get the same output wget --post-data "[email protected]&txtPassword=12345&txtpub=44" http://epaper.abc.com/login.aspx If I do: --save-cookies abc_cookies.txt it doesnt seem to have anything other than the default content.

• Chrome plugin removal

  - by kambamsu

  Hi, I'm writing an NPAPI plugin. In every webpage that the browser goes to, I inject my plugin with an object tag. Something like: <object id="myplugin" type="plugin-mime-type" > In some pages where i dont want it, after injection i remove it by finding the element using the id and doing a document.removeChild. From my logging i found that in firefox and opera, doing this automatically calls the plugin destroy method NPP_Destroy (NPAPI). But in chrome, it doesnt seem to call it. Is there any special way that i should remove a plugin in chrome that i am missing?? Any help would be appreciated. Thanks

• What programming technique / practice done by you was ahead of its time?

  - by Binoj Antony

  I once built a very good web application in ASP (classic) back in 2001 and extensively used XmlHttpRequest object in it. (I was lucky that the clients were only using IE, and only IE supported this object at that time). Then later when people started talking about AJAX in 2005, It felt good to have used something ahead (or early) of its time. Well, maybe this does not qualify to be listed as something done ahead of its time. Which programming technology/technique/practice have you done that was ahead of this time. One story per answer please. The title for this question taken from an opposite question here.

• Passing a non-iterable to list.extend ()

  - by JS

  Hello, I am creating a public method to allow callers to write values to a device, call it write_vals() for example. Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example: write_to_device([1,2,3]) or write_to_device(1) My function would like to work with a flat list, so I tried to be clever and code something like this: input_list = [] input_list.extend( input_val ) This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer: TypeError: 'int' object is not iterable Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten. Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods. Suggestions (coding-related only, please) would be greatly appreciated.

• Why won't this hit test fire a second time? wpf

  - by csciguy

  All, I have a main window that contains two custom objects (AnimatedCharacter). These objects are nothing but images. These images might contain transparent portions. One of these objects slightly overlaps the other object. There is a listener attached to the main window and is as follows. private void Window_MouseLeftButtonUp_1(object sender, MouseButtonEventArgs e) { Point pt = e.GetPosition((UIElement)sender); //store off the mouse pt hitPointMouse = pt; //clear the result list hitResultsSubList.Clear(); EllipseGeometry m_egHitArea = new EllipseGeometry(pt, 1, 1); VisualTreeHelper.HitTest(sender as Visual, HitTestFilterFuncNew, new HitTestResultCallback(HitTestCallback), new GeometryHitTestParameters(m_egHitArea)); //Check all sub items you have now hit if (hitResultsSubList.Count > 0) { CheckSubHitItems(hitResultsSubList); } } The idea is to filter out only a select group of items (called AnimatedCharacters). The hittest and filters are as follows public HitTestResultBehavior HitTestCallback(HitTestResult htrResult) { IntersectionDetail idDetail = ((GeometryHitTestResult)htrResult).IntersectionDetail; switch (idDetail) { case IntersectionDetail.FullyContains: return HitTestResultBehavior.Continue; case IntersectionDetail.Intersects: return HitTestResultBehavior.Continue; case IntersectionDetail.FullyInside: return HitTestResultBehavior.Continue; default: return HitTestResultBehavior.Stop; } } public HitTestFilterBehavior HitTestFilterFuncNew(DependencyObject potentialHitTestTarget) { if (potentialHitTestTarget.GetType() == typeof(AnimatedCharacter)) { hitResultsSubList.Add(potentialHitTestTarget as AnimatedCharacter); } return HitTestFilterBehavior.Continue; } This returns me back a list (called hitResultsSubList) that I attempt to then process further. I want to take everything in the hitResultsSubList and run a hit test on it again. This time, the hit test will be checking alpha levels on the particular animatedCharacter object. private void CheckSubHitItems(List<DependencyObject> hitResultsSub) { for(int i = 0; i<hitResultsSub.Count; i++) { hitResultsList.Clear(); AnimatedCharacter ac = hitResultsSub[i] as AnimatedCharacter; try { //DEBUGGER SKIPS THIS NEXT LINE EVERY SINGLE TIME. VisualTreeHelper.HitTest(ac, null, new HitTestResultCallback(hitCallBack), new PointHitTestParameters(hitPointMouse)); } catch (Exception e) { System.Diagnostics.Debug.WriteLine(e.StackTrace); } if (hitResultsList.Count > 0) { //do something here } } } Here is my problem now. The hit test in the second function (CheckSubHitItems) never gets called. There are definitely items (DependencyObjects of the type AnimatedCharacter) in the hitResultSub, but no matter what, the second hit test will not fire. I can walk the for loop fine, but when that line is hit, I get the following console statement. Step into: Stepping over non-user code 'System.MulticastDelegate.CtorClosed' No exceptions are thrown. Any help is appreciated.

• Suddenly blocked from a site

  Suddenly from a time to now I haven't been able to go to a site I used to go frequently for maintenance (Wordpress). I tried different browsers, restarting my laptop, clearing cache, history, cookies. Also did a ping to the site ip, go 4 packets send and 4 lost. This is a problem I think with only my laptop, since I've been able to go into the site from other devices in the same network. I have also tried connecting to the same site from a completely different network with the same problem. I really don't know what to do about this, any advices? PS: site hosted in wp engine if that has anything to do with this problem.

• Map only certain parts of the class to a database using SQLAlchemy?

  - by Az

  When mapping an object using SQLAlchemy, is there a way to only map certain elements of a class to a database, or does it have to be a 1:1 mapping? Example: class User(object): def __init__(self, name, username, password, year_of_birth): self.name = name self.username = username self.password = password self.year_of_birth = year_of_birth Say, for whatever reason, I only wish to map the name, username and password to the database and leave out the year_of_birth. Is that possible and will this create problems? Edit - 25/03/2010 Additionally, say I want to map username and year_of_birth to a separate database. Will this database and the one above still be connected (via username)?
