  • How to access and run field events from extension js?

    - by Dan Roberts
    I have an extension that helps in submitting forms automatically for a process at work. We are running into a problem with dual select boxes where one option is selected and then that selection changes another field's options. Since setting an option selected property to true doesn't trigger the field's onchange event I am trying to do so through code. The problem I've run into is that if I try to access or run functions on the field object from the extension, I get the error Error: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://webformsidebar/content/webformsidebar.js :: WebFormSidebar_FillProcess :: line 499" data: no] the line causing the error is... if (typeof thisField.onchange === 'function') The line right before it works just fine... thisField.options[t].selected=true; ...so I'm not sure why this is resulting in such an error. What surprises me most I guess is that checking for the existence of the function leads to an error. It feels like the problem is related to the code running in the context of the extension instead of the browser window document. If so, is there any way to call a function in the browser window context instead? Do I need to actually inject code into the page somehow? Any other ideas? Thanks

  • How can I prevent SerializeJSON from changing Yes/No/True/False strings to boolean?

    - by Dan Roberts
    I have a data struct being stored in JSON format, converted using the serializeJSON function. The problem I am running into is that strings that can be boolean in CF such as Yes,No,True,and False are converted into JSON as boolean values. Below is example code. Any ideas on how to prevent this? Code: <cfset test = {str='Yes'}> <cfset json = serializeJSON(test)> <cfset fromJSON = deserializeJSON(json)> <cfoutput> #test.str#<br> #json#<br> #fromJSON.str# </cfoutput> Result: Yes {"STR":true} YES

  • What is the Browser version of a WebBrowser control in Windows Forms

    - by Chris Roberts
    I'm building a Windows Forms application which makes use of the WebBrowser control. Can anyone tell me what rendering engine the control uses? Is it fixed based on the version of the .NET framework I'm developing against or is it based on the version of IE installed on the client's machine? Does the client even need IE? In other words, if a website looks right in my application on my machine, is it reasonably safe to assume it'll render right on everyone else's machine? Thanks!

  • Joining different models in Django

    - by Andrew Roberts
    Let's say I have this data model: class Workflow(models.Model): ... class Command(models.Model): workflow = models.ForeignKey(Workflow) ... class Job(models.Model): command = models.ForeignKey(Command) ... Suppose somewhere I want to loop through all the Workflow objects, and for each workflow I want to loop through its Commands, and for each Command I want to loop through each Job. Is there a way to structure this with a single query? That is, I'd like Workflow.objects.all() to join in its dependent models, so I get a collection that has dependent objects already cached, so workflows[0].command_set.get() doesn't produce an additional query. Is this possible?

  • Inserting newlines into a GtkTextView widget (GTK+ programming)

    - by Mark Roberts
    I've got a button which when clicked copies and appends the text from a GtkEntry widget into a GtkTextView widget. (This code is a modified version of an example found in the "The Text View Widget" chapter of Foundations of GTK+ Development.) I'm looking to insert a newline character before the text which gets copied and appended, such that each line of text will be on its own line in the GtkTextView widget. How would I do this? I'm brand new to GTK+. Here's the code sample: #include <gtk/gtk.h> typedef struct { GtkWidget *entry, *textview; } Widgets; static void insert_text (GtkButton*, Widgets*); int main (int argc, char *argv[]) { GtkWidget *window, *scrolled_win, *hbox, *vbox, *insert; Widgets *w = g_slice_new (Widgets); gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (GTK_WINDOW (window), "Text Iterators"); gtk_container_set_border_width (GTK_CONTAINER (window), 10); gtk_widget_set_size_request (window, -1, 200); w->textview = gtk_text_view_new (); w->entry = gtk_entry_new (); insert = gtk_button_new_with_label ("Insert Text"); g_signal_connect (G_OBJECT (insert), "clicked", G_CALLBACK (insert_text), (gpointer) w); scrolled_win = gtk_scrolled_window_new (NULL, NULL); gtk_container_add (GTK_CONTAINER (scrolled_win), w->textview); hbox = gtk_hbox_new (FALSE, 5); gtk_box_pack_start_defaults (GTK_BOX (hbox), w->entry); gtk_box_pack_start_defaults (GTK_BOX (hbox), insert); vbox = gtk_vbox_new (FALSE, 5); gtk_box_pack_start (GTK_BOX (vbox), scrolled_win, TRUE, TRUE, 0); gtk_box_pack_start (GTK_BOX (vbox), hbox, FALSE, TRUE, 0); gtk_container_add (GTK_CONTAINER (window), vbox); gtk_widget_show_all (window); gtk_main(); return 0; } /* Insert the text from the GtkEntry into the GtkTextView. */ static void insert_text (GtkButton *button, Widgets *w) { GtkTextBuffer *buffer; GtkTextMark *mark; GtkTextIter iter; const gchar *text; buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (w->textview)); text = gtk_entry_get_text (GTK_ENTRY (w->entry)); mark = gtk_text_buffer_get_insert (buffer); gtk_text_buffer_get_iter_at_mark (buffer, &iter, mark); gtk_text_buffer_insert (buffer, &iter, text, -1); } You can compile this command (assuming the file is named file.c): gcc file.c -o file `pkg-config --cflags --libs gtk+-2.0` Thanks everybody!

  • SimpleXML adding html into Hash tree

    - by Miriam Raphael Roberts
    Question: I have an xml file that I am pulling from the web and parsing. One of the items in the xml is a 'content' value that has HTML. I am using SimpleXML/XMLin to parse the file like so: $xml= eval { $data-XMLin($xmldata, forcearray = 1, suppressempty= +'') }; When I use Dumper to dump the hash, I dsicovered that SimpleXML is parsing the HTML into the hash tree. 'content' => { 'div' => [ { 'xmlns' => 'http://www.w3.org/1999/xhtml', 'p' => [ { 'a' => [ { 'href' => 'http://miamiherald.typepad.com/.a/6a00d83451b26169e20133ec6f4491970b-pi', 'style' => 'FLOAT: left', 'img' => [ etc..... This is not what I want. I want to just grab content inside of this entry. How do I do this?

  • Qt and variadic functions

    - by Noah Roberts
    OK, before lecturing me on the use of C-style variadic functions in C++...everything else has turned out to require nothing short of rewriting the Qt MOC. What I'd like to know is whether or not you can have a "slot" in a Qt object that takes an arbitrary amount/type of arguments. The thing is that I really want to be able to generate Qt objects that have slots of an arbitrary signature. Since the MOC is incompatible with standard preprocessing and with templates, it's not possible to do so with either direct approach. I just came up with another idea: struct funky_base : QObject { Q_OBJECT funky_base(QObject * o = 0); public slots: virtual void the_slot(...) = 0; }; If this is possible then, because you can make a template that is a subclass of a QObject derived object so long as you don't declare new Qt stuff in it, I should be able to implement a derived templated type that takes the ... stuff and turns it into the appropriate, expected types. If it is, how would I connect to it? Would this work? connect(x, SIGNAL(someSignal(int)), y, SLOT(the_slot(...))); If nobody's tried anything this insane and doesn't know off hand, yes I'll eventually try it myself...but I am hoping someone already has existing knowledge I can tap before possibly wasting my time on it.

  • How to rewrite url to include subdirectory?

    - by Jason Roberts
    The following set of rewrite rules rewrite any urls formatted as foo.mydomain.com/bar to mydomain.com/mysubs/foo/bar.php. This all works fine except if I have a subdirectory named 'blah' in the original url such as foo.mydomain.com/blah/bar, then it will rewrite it as mydomain.com/mysubs/foo/bar (without the blah subdirectory) when what I need is the url to be rewritten as mydomain.com/mysubs/foo/blah/bar. So, what do I need to change to make this work correctly? Options +FollowSymLinks Options -Indexes RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !www.mydomain.com$ [NC] RewriteCond %{HTTP_HOST} ^([^./]+)\.mydomain\.com$ RewriteRule !^mysubs/ mysubs/%1%{REQUEST_URI} [L] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php

  • view handler design pattern

    - by Mark Roberts
    I'm trying to figure out the origin of the view handler design pattern in software engineering. Many of the design patterns in software engineering were inspired by things which pre-date computers, and I was wondering if anybody had any insights on the origin of this particular pattern.

  • Linq with a long where clause

    - by Jeremy Roberts
    Is there a better way to do this? I tried to loop over the partsToChange collection and build up the where clause, but it ANDs them together instead of ORing them. I also don't really want to explicitly do the equality on each item in the partsToChange list. var partsToChange = new Dictionary<string, string> { {"0039", "Vendor A"}, {"0051", "Vendor B"}, {"0061", "Vendor C"}, {"0080", "Vendor D"}, {"0081", "Vendor D"}, {"0086", "Vendor D"}, {"0089", "Vendor E"}, {"0091", "Vendor F"}, {"0163", "Vendor E"}, {"0426", "Vendor B"}, {"1197", "Vendor B"} }; var items = new List<MaterialVendor>(); foreach (var x in partsToChange) { var newItems = ( from m in MaterialVendor where m.Material.PartNumber == x.Key && m.Manufacturer.Name.Contains(x.Value) select m ).ToList(); items.AddRange(newItems); } Additional info: I am working in LINQPad.

  • how to send an array of bytes over a TCP connection (java programming)

    - by Mark Roberts
    Can somebody demonstrate how to send an array of bytes over a TCP connection from a sender program to a receiver program in Java. (I'm new to Java programming, and can't seem to find an example of how to do this that shows both ends of the connection (sender and receiver.) If you know of an existing example, maybe you could post the link. (No need to reinvent the wheel.) P.S. This is NOT homework! :-)

  • Policy based design and defaults.

    - by Noah Roberts
    Hard to come up with a good title for this question. What I really need is to be able to provide template parameters with different number of arguments in place of a single parameter. Doesn't make a lot of sense so I'll go over the reason: template < typename T, template <typename,typename> class Policy = default_policy > struct policy_based : Policy<T, policy_based<T,Policy> > { // inherits R Policy::fun(arg0, arg1, arg2,...,argn) }; // normal use: policy_base<type_a> instance; // abnormal use: template < typename PolicyBased > // No T since T is always the same when you use this struct custom_policy {}; policy_base<type_b,custom_policy> instance; The deal is that for many abnormal uses the Policy will be based on one single type T, and can't really be parameterized on T so it makes no sense to take T as a parameter. For other uses, including the default, a Policy can make sense with any T. I have a couple ideas but none of them are really favorites. I thought that I had a better answer--using composition instead of policies--but then I realized I have this case where fun() actually needs extra information that the class itself won't have. This is like the third time I've refactored this silly construct and I've got quite a few custom versions of it around that I'm trying to consolidate. I'd like to get something nailed down this time rather than just fish around and hope it works this time. So I'm just fishing for ideas right now hoping that someone has something I'll be so impressed by that I'll switch deities. Anyone have a good idea? Edit: You might be asking yourself why I don't just retrieve T from the definition of policy based in the template for default_policy. The reason is that default_policy is actually specialized for some types T. Since asking the question I have come up with something that may be what I need, which will follow, but I could still use some other ideas. template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename T > struct default_policy< test<T, default_policy> > { void f() {} }; template < > struct default_policy< test<int, default_policy> > { void f(int) {} }; Edit: Still messing with it. I wasn't too fond of the above since it makes default_policy permanently coupled with "test" and so couldn't be reused in some other method, such as with multiple templates as suggested below. It also doesn't scale at all and requires a list of parameters at least as long as "test" has. Tried a few different approaches that failed until I found another that seems to work so far: template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename PolicyBased > struct fetch_t; template < typename PolicyBased, typename T > struct default_policy_base; template < typename PolicyBased > struct default_policy : default_policy_base<PolicyBased, typename fetch_t<PolicyBased>::type> {}; template < typename T, template < typename > class Policy > struct fetch_t< test<T,Policy> > { typedef T type; }; template < typename PolicyBased, typename T > struct default_policy_base { void f() {} }; template < typename PolicyBased > struct default_policy_base<PolicyBased,int> { void f(int) {} };

  • How to pass initialisation parameters to a web service in Netbeans

    - by Bob Roberts
    I have built a web web service with Netbeans 6.8 using the "Web Service from WSDL" wizard. It has generated the binding classes and a skeleton for the class implementing the web service. I've set some initialization parameters in web.xml, under the servlet corresponding to the web service. Now I'd like to pass those parameters to the class implementing the web service. How can this be achieved (preferably without editing any of the code auto-generated by Netbeans)?

  • converting an array of characters to a const gchar*

    - by Mark Roberts
    I've got an array of characters which contains a string: char buf[MAXBUFLEN]; buf[0] = 'f'; buf[1] = 'o'; buf[2] = 'o'; buf[3] = '\0'; I'm looking to pass this string as an argument to the gtk_text_buffer_insert function in order to insert it into a GtkTextBuffer. What I can't figure out is how to convert it to a const gchar *, which is what gtk_text_buffer_insert expects as its third argument. Can anybody help me out?

  • Which function pair in QString to use for converting to/from std::string?

    - by Noah Roberts
    I'm working on a project that we want to use Unicode and could end up in countries like Japan, etc... We want to use std::string for the underlying type that holds string data in the data layer (see Qt, MSVC, and /Zc:wchar_t- == I want to blow up the world as to why). The problem is that I'm not completely sure which function pair (to/from) to use for this and be sure we're 100% compatible with anything the user might enter in the Qt layer. A look at to/fromStdString indicates that I'd have to use setCodecForCStrings. The documentation for that function though indicates that I wouldn't want to do this for things like Japanese. This is the set that I'd LIKE to use though. Does someone know enough to explain how I'd set this up if it's possible? The other option that looks like I could be pretty sure of it working is the to/fromUTF8 functions. Those would require a two step approach though so I'd prefer the other if possible. Is there anything I've missed?

  • Android Calendar API vs Calendar Provider API

    - by John Roberts
    I'm a little bit confused about the difference between the two. An example of the Calendar API is supposedly located here: http://samples.google-api-java-client.googlecode.com/hg/calendar-android-sample/instructions.html, but the author himself suggests using the Calendar Provider API, details about which are here: http://developer.android.com/guide/topics/providers/calendar-provider.html. Can someone explain to me the difference between the two, and which would be better for me to use for a simple calendar app?

  • NSDirectoryEnumerator And Subfolders

    - by Matthew Roberts
    I have an iPhone app that searches a folder, collates an an array of all the audio files, and lets them be played back. The problem is that if there is a subfolder within the folder I am searching, it will just skip over it/not go into its contents. My code is as follows: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectory]; NSString *pname; while (pname = [direnum nextObject]) { [musicArray addObject:[pname stringByDeletingPathExtension]]; } What I want to do is continue to search its subfolders, how would I go about doing that?

  • Does it exist: smart pointer, owned by one object allowing access.

    - by Noah Roberts
    I'm wondering if anyone's run across anything that exists which would fill this need. Object A contains an object B. It wants to provide access to that B to clients through a pointer (maybe there's the option it could be 0, or maybe the clients need to be copiable and yet hold references...whatever). Clients, lets call them object C, would normally, if we're perfect developers, be written carefully so as to not violate the lifetime semantics of any pointer to B they might have...but we're not perfect, in fact we're pretty dumb half the time. So what we want is for object C to have a pointer to object B that is not "shared" ownership but that is smart enough to recognize a situation in which the pointer is no longer valid, such as when object A is destroyed or it destroys object B. Accessing this pointer when it's no longer valid would cause an assertion/exception/whatever. In other words, I wish to share access to data in a safe, clear way but retain the original ownership semantics. Currently, because I've not been able to find any shared pointer in which one of the objects owns it, I've been using shared_ptr in place of having such a thing. But I want clear owneship and shared/weak pointer doesn't really provide that. Would be nice further if this smart pointer could be attached to member variables and not just hold pointers to dynamically allocated memory regions. If it doesn't exist I'm going to make it, so I first want to know if someone's already released something out there that does it. And, BTW, I do realize that things like references and pointers do provide this sort of thing...I'm looking for something smarter.
