• Firefox extension dev: observing preferences, avoid multiple notifications

  - by Michael

  Let's say my Firefox extension has multiple preferences, but some of them are grouped, like check interval, fail retry interval, destination url. Those are used in just single function. When I subscribe to preference service and add observer, the observe callback will be called for each changed preference, so if by chance user changed all of the settings in group, then I will have to do the same routine for the same subsystem as many times as I have items in that preferences group. It's a great redundancy! What I want is observe to be called just once for group of preferences. Say extensions.myextension.interval1 extensions.myextension.site extensions.myextension.retry so if one or all of those preferences are changed, I receive only 1 notification about it. In other words, no matter how many preferences changed in branch, I want the observe callback to called once.

• Not able to pass multiple override parameters using nose-testconfig 0.6 plugin in nosetests

  - by Jaikit

  Hi, I am able to override multiple config parameters using nose-testconfig plugin only if i pass the overriding parameters on commandline. e.g. nosetests -c nose.cfg -s --tc=jack.env1:asl --tc=server2.env2:abc But when I define the same thing inside nose.cfg, than only the value for last parameter is modified. e.g. tc = server2.env2:abc tc = jack.env1:asl I checked the plugin code. It looks fine to me. I am pasting the part of plugin code below: parser.add_option( "--tc", action="append", dest="overrides", default = [], help="Option:Value specific overrides.") configure: if options.overrides: self.overrides = [] overrides = tolist(options.overrides) for override in overrides: keys, val = override.split(":") if options.exact: config[keys] = val else: ns = ''.join(['["%s"]' % i for i in keys.split(".") ]) # BUG: Breaks if the config value you're overriding is not # defined in the configuration file already. TBD exec('config%s = "%s"' % (ns, val)) Let me know if any one has any clue.

• Databinding multiple tables linq query to gridview?

  - by Curtis White

  My question is how can I display a linq query in a gridview that has data from multiple tables AND allow the user to edit some of the fields or delete the data from a single table? I'd like to do this with either a linqdatasource or a linq query. I'm aware I can set the e.Result to the query on the selecting event. I've also been able to build a custom databound control for displaying the linq relations (parent.child). However, I'm not sure how I can make this work with delete? I'm thinking I may need to handle the delete event with custom code.

• Popping multiple levels in UITableViewController

  - by LavaSlider

  I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed. I tried: [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; [self.navigationController popViewControllerAnimated: NO]; and [self.navigationController popViewControllerAnimated: NO]; [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

• Extending Multiple models in Codeigniter 2

  - by Rooneyl

  How do you set up CI2 to allow extending of multiple models? I can only get it to extend one model (put in /application/core) named MY_Model (case sensitive). To choose what model to extend I am doing; in the model.. require_once APPPATH.'core/MY_Another_model.php'; class Test_model extends MY_Another_model { ... } I can't find where in the core system code where it states only to allow models that are being extended to be called MY_Model. Thank you for any and all help.

• Editing Multiple files in vi with Wildcards

  - by Alan Storm

  When using the programmers text editor vi, I'll often using a wildcard search to be lazy about the file I want to edit vi ThisIsAReallLongFi*.txt When this matches a single file it works great. However, if it matches multiple files vi does something weird. First, it opens the first file for editing Second, when I :wq out of the file, I get a message the bottom of the terminal that looks like this E173: 4 more files to edit Hit ENTER or type command to continue When I hit enter, it returns me to edit mode in the file I was just in. The behavior I'd expect here would be that vi would move on to the next file to edit. So, What's the logic behind vi's behavior here Is there a way to move on and edit the next file that's been matched? And yes, I know about tab completion, this question is based on curiosity and wanting to understand the shell better.

• C++/MFC: Handling multiple CListCtrl's headers HDN_ITEMCLICK events

  - by raph.amiard

  I'm coding an MFC application in which i have a dialog box with multiple CListCtrls in report view. I want one of them to be sortable. So i handled the HDM_ITEMCLICK event, and everything works just fine .. Except that if i click on the headers of another CListCtrl, it does sort the OTHER CListCtrl, which does look kind of dumb. This is apparently due to the fact that headers have an ID of 0, which make the entry in the message map look like this : ON_NOTIFY(HDN_ITEMCLICK, 0, &Ccreationprogramme::OnHdnItemclickList5) But since all the headers have an id of zero, apparently every header of my dialog sends the message. Is there an easy way around this problem ?

• Managing multiple WCF endpoints for the same service

  - by Jacob

  I am building an single application that uses WCF to call out to multiple external endpoints. All of the remote endpoints are identical except for the URI. I would like to treat them as a pool: add and remove endpoints through configuration and have the application understand what to do. My original plan was to define one endoint in the app.config, then iterate over my list of endpoints and update client.Endpoint.Address on the fly to point to the right place. Unfortunately, that property is read-only, rendering that plan unworkable. I'm a little bit stumped here. Any suggestions on how I might accomplish this?

• DialogBox in Win32 - Prevent multiple instance

  - by UK

  Hello all, I have a program which creates DialogBox window when user clicks the menu item from tray icon, case ID_OPTIONS: DialogBox ( GetModuleHandle ( NULL ), MAKEINTRESOURCE ( IDD_SETUP_DIALOG ), hWnd, reinterpret_cast<DLGPROC>(SetupDlgProc) ); return 0; But the problem here is everytime when users clicks item from tray , a new instance of the dialogbox appears. Is there anyway to prevent this multiple instance ? BTW, my SetupDlgProc looks like this, BOOL CALLBACK SetupDlgProc ( HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam ) { switch ( Message ) { case WM_INITDIALOG: ... } } Thanks for your help.

• Working with multiple input and output files in Python

  - by Morlock

  I need to open multiple files (2 input and 2 output files), do complex manipulations on the lines from input files and then append results at the end of 2 output files. I am currently using the following approach: in_1 = open(input_1) in_2 = open(input_2) out_1 = open(output_1, "w") out_2 = open(output_2, "w") # Read one line from each 'in_' file # Do many operations on the DNA sequences included in the input files # Append one line to each 'out_' file in_1.close() in_2.close() out_1.close() out_2.close() The files are huge (each potentially approaching 1Go, that is why I am reading through these input files one at a time. I am guessing that this is not a very Pythonic way to do things. :) Would using the following form good? with open("file1") as f1: with open("file2") as f2: # etc. If yes, could I do it while avoiding the highly indented code that would result? Thanks for the insights!

• Finding matches between multiple JavaScript Arrays

  - by Chris Barr

  I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

• Using multiple SWF Object - Flash doesn't focus on rollover

  - by WiseDonkey

  I've got a page with multiple embeds of Flash objects, including dynamically created graphs. I'm including them all with SWF Object JS declared in the header. It works fine in the fact that all are loaded. But, for some reason when you move down on the page (so they're out of view) and back, or click on another object it no longer has focus when you're rolling over. I.e. I have a flash menu that moves on rollover. When you go down the page, click on something, then go back up it no longer response to rollover. I've seen bits on here and elsewhere about losing focus in Firefox (which is the browser Im using - i havent managed to find this bug in IE) but it's talking about literally not being able to type or whatever, when you click on it. This is on rollover. Has anyone got any advice or thoughts on this subject?

• Algorithm - combine multiple lists, resulting in unique list and retaining order

  - by hitch

  I want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.: 1: A C E 2: D E 3: B A D result: B A C D E above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A. If there are conflicting orderings, the first ordering should be used. i.e. 1: A C E 2: B D E 3: F D result: A C B D E F 3 conflicts with 2, therefore requirements for 2 will be used. If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained. This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.

• Start multiple processes of a dll in delphi

  - by Tom

  I have a "ActiveX library" project created with Delphi 2007. The library interface return XML data based on input values. This is then used by a PHP script that displays the data on a web page. This works great! The problem is that i can only run one instance of the dll process on the server. However, for security reasons, each of my customer should be able to access their own process of the dll (because the dll is always connected to only one database). Also, because of the way the delphi code is built, it doesn't support multiple threads. (It's a 100 000+ lines project using lots of singleton classes) Is there a way of starting several instances of the same dll? Is there a better way of transferring XML data from delphi to PHP? Sorry for the longish question, any help is appreciated (ps. I know the delphi code should be refactored, but this would mean 6 months of "circular reference" -hell :)

• Multiple Progress Bar States in WPF

  - by kbo206

  I'm currently developing a WPF application in C# and I want to have a progress bar control that can be in a "paused" state as well as an "error" state. Much like this: http://wyday.com/windows-7-progress-bar/ Unfortunately, that's a Windows Forms control and implementing it via a Windows Forms Host proved to be incompatible. My question is, how can I go about accomplishing a similar effect in WPF? Is it possible to make multiple "states" of a progress bar? Is this kind of operation in WPF but I'm just looking over it? I'm mainly talking about the progress bar itself here, I'm pretty sure I know how to achieve this in the taskbar. All help is appreciated, especially code examples. Thanks!

• Multiple classes in a Python module

  - by ralphL

  I'm very new to Python (I'm coming from a JAVA background) and I'm wondering if anyone could help me with some of the Python standards. Is it a normal or "proper" practice to put multiple class in a module? I have been working with Django and started with the tutorials and they place their database model classes in the same module. Is this something that is normally done or should I stick with 1 class per module? Is their a reason I would do one over the other? Hope I'm being clear and not to generic. Thanks to everyone in advance!

• How to add multiple files to py2app?

  - by Niek de Klein

  I have a python script which makes a GUI. When a button 'Run' is pressed in this GUI it runs a function from an imported package (which I made) like this from predictmiP import predictor class MiPFrame(wx.Frame): [...] def runmiP(self, event): predictor.runPrediction(self.uploadProtInterestField.GetValue(), self.uploadAllProteinsField.GetValue(), self.uploadPfamTextField.GetValue(), \ self.edit_eval_all.Value, self.edit_eval_small.Value, self.saveOutputField) When I run the GUI directly from python it all works well and the program writes an output file. However, when I make it into an app, the GUI starts but when I press the button nothing happens. predictmiP does get included in build/bdist.macosx-10.3-fat/python2.7-standalone/app/collect/, like all the other imports I'm using (although it is empty, but that's the same as all the other imports I have). How can I get multiple python files, or an imported package to work with py2app?

• make: invoke command for multiple targets of multiple files?

  - by marvin2k

  Hi, I looking to optimize an existing Makefile. It's used to create multiple plots (using Octave) for every logfile in a given directory using an scriptfile for every plot which takes a logfilename as an argument. In the Moment, I use one single rule for every kind of plot available, with a handwritten call to Octave, giving the specific scriptfile/logfile as an argument. It would be nice, if every plot has "his" octave-script as a dependency (plus the logfile, of course), so only one plot is regenerated if his script is changed. Since I don't want to type that much, I wonder how I can simplifiy this by using only one general rule to build "a" plot? To make it clearer: Logfile: "$(LOGNAME).log" Scriptfile: "plot$(PLOTNAME).m" creates "$(LOGNAME)_$(PLOTNAME).png" The first thing I had in mind: %1_%2.png: %1.log $(OCTAVE) --eval "plot$<2('$<1')" But this seems not to be allowed. Could someone give me a hint?

• Fast read of certain bytes of multiple files in C/C++

  - by Alejandro Cámara

  I've been searching in the web about this question and although there are many similar questions about read/write in C/C++, I haven't found about this specific task. I want to be able to read from multiple files (256x256 files) only sizeof(double) bytes located in a certain position of each file. Right now my solution is, for each file: Open the file (read, binary mode): fstream fTest("current_file", ios_base::out | ios_base::binary); Seek the position I want to read: fTest.seekg(position*sizeof(test_value), ios_base::beg); Read the bytes: fTest.read((char *) &(output[i][j]), sizeof(test_value)); And close the file: fTest.close(); This takes about 350 ms to run inside a for{ for {} } structure with 256x256 iterations (one for each file). Q: Do you think there is a better way to implement this operation? How would you do it?

• Java array assignment (multiple values)

  - by Danny King

  Hello, I have a Java array defined already e.g. float[] values = new float[3]; I would like to do something like this further on in the code: values = {0.1f, 0.2f, 0.3f}; But that gives me a compile error. Is there a nicer way to define multiple values at once, rather than doing this?: values[0] = 0.1f; values[1] = 0.2f; values[2] = 0.3f; Thanks!
