• using special characters in functions: Python

  - by satyajit

  I am writing an xmlrpc client which uses a server written in ruby. One of the functions is framework.busy?(). Let me show the ruby version: server.call( "framework.busy?" ) So lets assume I create an instance of the ServerProxy class say server. So while using python to call the function busy? I need to use: server.framework.busy?() This leads to an error: SyntaxError: invalid syntax How can I call this function? Or am I reading the ruby code wrong and implementing it wrongly.

• Delete file after sharing via intent.

  - by Matt

  I'm trying to delete a temporary file after sharing it via android's Intent.ACTION_SEND feature. Right now I am starting the activity for a result and in OnActivityResult, I am deleting the file. Unfortunately this only works if I am debugging it with a breakpoint, but when I let it run freely and say, email the file, the email has no attachment. I think what is happening is my activity is deleting the file before it had been emailed. What I don't get is why, shouldn't onActivityResult only be called AFTER the other activity is finished? I have also tried deleting the file in onResume, but no luck. Is there a better way to do this?

• How to define a function which repeats itself when passed an argument

  - by ~unutbu

  Is there an easy way to define a function which repeats itself when passed an argument? For example, I've defined the following function (defun swap-sign () (interactive) (search-forward-regexp "[+-]") (if (equal (match-string 0) "-") (replace-match "+") (replace-match "-")) ) I'd like C-u swap-sign to call swap-sign four times. I've tried (defun swap-sign (&optional num) (interactive) (let ((counter 0) (num (if num (string-to-number num) 0))) (while (<= counter num) (search-forward-regexp "[+-]") (if (equal (match-string 0) "-") (replace-match "+") (replace-match "-")) (setq counter (1+ counter))))) but C-u swap-sign still only runs swap-sign (or perhaps more precisely, the body of the while-loop) once. I'm guessing it is because if num is not the right way to test if num is an empty string. Am I on the right track, or is there a better/easier way to extend swap-sign?

• save state of external running program

  - by SuitUp

  Hi, my goal is to save state of running process and later start from this point. This is not necessary need to be state from this exact moment, let's say save after 5 seconds is good too. Problem is, i can't alter in code of this external program, i am even don't aware of it's architecture. I have resources to save whole program to disk from memory, but i need some tips, where to start. I can't use any VM like Virtual Box to save state of whole operating system, and program can be written in c++ or c or c#...

• Does duplicate id's screw up jquery selectors?

  - by Matt

  If I had two divs, both with id="myDiv" Would $("#myDiv").fadeOut(); fade both divs out? Or would it fade only the first/second? Or none at all? How do I change which one it fades out? Note: I know duplicate id's is against standards but I'm using the fancybox modal popup and it duplicates specified content on your page for the content of the popup. If anyone knows a way around this (maybe I'm using fancybox wrong) please let me know.

• CDateTimeCtrl - preventing 'focus' change when setting date

  - by WalderFrey

  I'd like to use a CDateTimeCtrl to allow the user to select a non-weekend date. So, if the user increments the day (via a keypress) - and the resulting day is found to fall on a weekend - then the control should skip forward to the following Monday (don't let issues about month changes distract you, it's not relevant). Usually it's not a problem: when I handle the DTN_DATETIMECHANGE notification I can check the new date/time and if it's found to be a weekend then I can call SetTime on the control to update the date. However, if I set the style to DTS_SHOWNONE, this call to SetTime causes the control to shift the input 'focus' (term used loosely) to the 'none' checkbox, e.g. away from the day field. This prevents the user from using keyboard input to continue incrementing the date unless they subsequently use the right arrow key to reset the 'focus', which is just nasty. I would dearly like to prevent this focus shift from occurring. Is it even possible?

• Tool To Catch All The Inputs That Cause Crash?

  - by Barakat

  Hi all, I need a Windows tool records inputs and debugging informations that cause program's crashing. I don't mean a fuzzing tool ! Ammmmm ... let me show you a scenario may explain what I'm talking about.

Because that the data that cause the crash no longer exist. So I need a tool records all the inputs and debugging informations to find helpful informations to reuse the inputs data to make the program crashes under a debaucher in order to understand how the crash happen.

• R problems using rpart with 4000 records and 13 attributes

  - by josh

  I have attempted to email the author of this package without success, just wondering if anybody else has experienced this. I am having an using rpart on 4000 rows of data with 13 attributes. I can run the same test on 300 rows of the same data with no issue. When I run on 4000 rows, Rgui.exe runs consistently at 50% cpu and the UI hangs.... it will stay like this for at least 4-5hours if I let it run, and never exit or become responsive. here is the code I am using both on the 300 and 4000 size subset : train<-read.csv("input.csv",header=T) y<-train[,18] x<-train[,3:17] library(rpart) fit<-rpart(y~.,x) Is this a known limitation of rpart, am I doing something wrong? potential workarounds? any assistance appreciated

• Access to an "upper" instance of a class from another instance of a different class

  - by BorrajaX

  Hello everyone! I have a tricky question and probably what I want to do is not even possible but... who knows... Python seems very flexible and powerful... I'd like to know if there's a way to access to the class (or its fields) where an object is instanciated. Let's say I have: def Class1: def __init__(self): self.title = "randomTitle" self.anotherField = float() self.class2Field = Class2() and the class whose type will be the class2Field: def Class2: def __init__(self): self.field1 = "" self.field2 = "" # . . . # I'd like to know if there's a way to access the instance of Class1 from the instance of Class2 that is declared in Class1 (meaning, accessing the fields of Class1 from the variable self.class2Field in that Class1 instance) I know I can always change the init in Class2 to accept a Class1 parameter, but I'd like to know if there's another way of "climbing" through the class hierachy... Thank you very much!

• How to use all the cores in Windows 7?

  - by Anon

  I am not sure if this belongs to Stackoverflow or Superuser but I thought I would ask here. I have a console based application written in C which currently takes about an hour to terminate in Windows 7 64-bit OS. The task manager reports that the application is using only 25% of the available CPU. I would like to reduce the run time by increasing cpu usage. Is there any way to let the application use all four cores (the laptop has Core i5) instead of just one? I am assuming that task manager reports 25% because only one core is allocated to the program.

• looping through new div as they are created

  - by eknown

  I have a div, let's call it class="phoneNo". Inside the div there are two links, one to add another div just like it, and another to delete the div itself. I'm trying to create a loop where if there's only 1 of these divs, the "delete" link should hide, and if there are more than 1 of these divs, the "delete" link should show up on all the divs. So far I came up with this, but no success: var pCount = $(".phoneNo").length; $(pCount).each(function(){ if (pCount <= 1) { $("a.deleteThis").hide(); } else if (pCount >= 1) { $("a.deleteThis").show(); } return true; });

• load balancer question c# asp.net

  - by Migs

  The place where I work has 2 servers and a load balancer. The setup is horrible since I have to manually make sure both servers have the same files. I know there are ways to automate this but it has not been implemented, hopefully soon (I have no control over this). I wrote an application that collects a bunch of information from a user, then creates a folder named after the email of the user in one of the servers. The problem is that I can't control in which server the folder gets created in, so let say a user goes in.. fills his stuff and his folder gets created in server 1, user goes away for a while and goes back to the site but this time the load balancer throws the user into server 2, now the user does something that needs to be saved into his folder but since it didn't created in this server an error occurs. What can I do about this? any suggestions? Thanks

• How to I get raw 'mouse' events with touch screens on Windows Vista/7?

  - by Emil

  Does anyone have a clue how to completely disable the touch/tablet 'magic' introduced in Windows Vista? When I follow the steps on http://msdn.microsoft.com/en-us/library/bb969148(VS.85).aspx (both SetProp disable and WM_TABLET_QUERYSYSTEMGESTURESTATUS override) I succeed in stopping windows from treating press-and-hold as a right-click (it correctly gives me a WM_LBUTTONDOWN), but it also gives me a premature WM_LBUTTONUP (before I really let go of the screen). And there is also another problem: a click followed by a drag (down, up, down, move) is treated as a double-click (down, up, down, up, move). These issues occur with two very different touch screens (so it is not a hardware problem), and it never used to happen with Windows XP. This really bugs me. I would much rather have the raw input events like you have for normal mouse clicks. Any ideas?

• Check if NSMutableArray contains text from textfield

  - by Polo Swelsen

  I want to check if the text inserted in a textfield is also in my NSMutableArray. So let's say my NSMutableArray has these objects: "Hey, Hello, No, Yes". Then when a user enters the text: "Hello" i want there to appear a UIAlertView. I now have the following: for (int slt = 0; slt < [zouten count]; slt++) { if (zout.text = [zouten objectAtIndex:slt]) { alert = [[UIAlertView alloc]initWithTitle:@"Goedzo!" message:[NSString stringWithFormat:@"Je hebt een zout gevonden"] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; } } [alert show]; But somehow the message appears with every word. what am i doing wrong?

• Finding the heaviest of N objects using M scales

  - by cpprulez

  We have N objects and M scales. It's up to us what the objects are, and we need to position the objects on the scales so that it is undoubtful which is the heaviest object. For example, if we have 3 objects: "a", "b", "c" and 2 scales, one possible solution is "a" "b", "b" = "c" (here "a" is the heaviest). I need an algorithm which generates such solutions given N and M. Also let's assume that "a" is always the heaviest object. I've lost a few hours figuring out how to do it, but no matter what I figure out, there's always cases which I miss. For example, another solution is: "a" + "c" = 2 * "b", "a" "c".

• .save puts NULL in user_id field in Ruby on Rails

  - by mathee

  Here's the model file: class ProfileTag < ActiveRecord::Base def self.create_or_update(options = {}) id = options.delete(:id) record = find_by_id(id) || new record.id = id record.attributes = options puts "record.profile_id is" puts record.profile_id record.save! record end end This gives me the correct print out in my log. But it also says that there's a call to UPDATE that sets profile_id to NULL. I'm not sure I understand why the INSERT puts the value into profile_id properly, but then it sets it to NULL on an UPDATE. If you need more specifics, please let me know. I'm thinking that the save functionality does many things other than INSERTs into the database, but I don't know what I need to specify so that it will properly set profile_id.

• How to write multiple files from one NSData object?

  - by Kevin Cupp

  Hi there! I'm writing an iPhone app that includes in-app purchasing. It downloads a zip file, then I unzip the file using the popular NSData category (zlibDeflate) which outputs the uncompressed file into an NSData object. The zip file contains multiple files in it which I need to write to the Documents directory. How can I write each file separately from this one NSData object? writeToFile just writes the whole thing to one file. Thank you and let me know if you need any more information.

• Set The Progress Bar Over 100% C#

  - by PhaDaPhunk

  its my first time using a ProgressBar in c#. The idea is to use the ProgressBar as an health bar in a simple game. The thing is I think the bar's maximum value is 100% but i would like to give it a higher value like let's say 1000% or, not sure if it's possible, give the bar an integer value instead of a percentage. progressBar1.Increment(100); This is where I initialize the health to 100points. Even if I use this syntax: progressBar1.Increment(1000); And I subtract : progressBar1.Increment(-25); The player is loosing 1/4 of is life as if he only had 100 Health Points. Any idea how I could change the maximum Bar value? Thanks in advance.

• Can you use Win32 GUI in a browser plugin?

  - by John

  Of course it would mean you're plugin is not cross-platform but let's focus on the technical side... Is a browser plugin (like done in NPAPI) restricted in what it can do? Or do you get fairly free reign to access the PC and the render-window you're given? For instance can you create Win32/MFC controls in your browser this way? A side question - is your browser plugin conceptually akin to a .DLL, which is therefore just arbitrary compiled code implementing a specific interface for browser control/communication?

• how to exchange variables between extern iframe and site

  - by helle

  hey guys, for developement reasons (working with facebook-connect) i put the connect iframe in an iframe. on that way i am able to work on the connect-thing independent of my ip and don't have to develop on the live-server. the iframe holding the connect-button iframe is on my server, accessing the same db-server as the developer version (developer version is running on localhsot). as far as good ... BUT how can i let the parent site know, that the user has connected, so that i get his profile-picture displayd as reaction to this? how can i react in generally on an action/event/JS in an iframe? is there a way? can the iframe post data to the parent site? like a time-stamp and fb_userid? if the iframe stuff doesn't work ... i thougt of saving the ip to the fb_userid (to db) and check matches ... but i don't like this idea.
