  • is counter has certain value inside a class in python

    - by mazlor
    i am learning classes in python and when i was reading the documentation i found this example that i didn't understand : class MyClass: """A simple example class""" def __init__(self): self.data = [] i = 12345 def f(self): return 'hello world' then if we assign : x = MyClass() x.counter = 1 now if we implement while loop : while x.counter < 10: x.counter = x.counter * 2 so the value of x.counter will be : 16 while for example if we have a variable y : y = 1 while y < 1 : y = y *2 then if we look for the value of y we find it 1 so i don't know how is the value of counter became 16 . thanks

  • Is vbscripting that difficult?

    - by eric young
    I need to write some vbscripts in my new project. I was told by other people that vbscripting is easy, but seems to me, it is not. For example, in the following example (provided by microsoft), these functions: CreateObject, CreateShortcut, as well as these property names: TargetPath, WindowStyle, Hotkey, etc, are used, but I just cannot find the corresponding API documentation about how to use them. In other words, how do you know you need to call these functions in your vbscripts? Visual Studio 2008/2010 do not have templates for vbscript either. Could anybody tell me what I am missing, and what the best way is to do vbscripting? set WshShell = WScript.CreateObject("WScript.Shell") strDesktop = WshShell.SpecialFolders("Desktop") set oShellLink = WshShell.CreateShortcut(strDesktop _ & "\MyExcel.lnk") oShellLink.TargetPath = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE" oShellLink.WindowStyle = 1 oShellLink.Hotkey = "CTRL+SHIFT+F" oShellLink.IconLocation = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE, 0" oShellLink.Description = "My Excel Shortcut" oShellLink.WorkingDirectory = strDesktop oShellLink.Save

  • python win32 simulate click

    - by nabizan
    Let's say I've got a window for which I want to simulate a mouse click at a specific x, y coordinate. I already have the hwnd but I'm not sure how to construct the lParam. I've used SendMessage in the past to click on buttons, etc., but I knew their hwnds. Any help would be greatly appreciated. I also can't help but wonder if I'm going about this the right way. My end goal is clicking on a certain user on skype main window (for example). I used EnumChildWindows to find all the main window's children, but couldn't find the right one. So figured I would try to 'click' on it using coordinates.

  • How to get time difference in milliseconds

    - by jason45
    Hi, I can't wrap my brain around this one so I hope someone can help. I have a song track that has the song length in milliseconds. I also have the date the song played in DATETIME format. What I am trying to do is find out how many milliseconds is left in the song play time. Example $tracktime = 219238; $dateplayed = '2011-01-17 11:01:44'; $starttime = strtotime($dateplayed); I am using the following to determine time left but it does not seem correct. $curtime = time(); $timeleft = $starttime+round($tracktime/1000)-$curtime; Any help would be greatly appreciated.

  • C++: FFMPEG and SDL resources

    - by advs89
    I'm looking for resources (preferably books, but websites are fine too) for using FFMPEG and/or SDL with C++. Stuff I'd like to be able to do (eventually): Decode and play videos in realtime to a QT widget (the QT part isn't a problem) Overlay text and images on the video (in realtime) Loop video Cross-fade from one video to another (in realtime) Some kind of DVD functionality LIVE sources? (i.e. webcam, stream, etc.) So far I've looked at (and consider helpful) the following resources: FFMPEG and SDL Tutorial by Dranger (extremely helpful) StackOverflow: ffmpeg C API documentation/tutorial (not a duplicate, btw) Sample code bundled with FFMPEG libraries (I'll try and update this list with anything helpful below) Thanks for any help... Also: Operating System is Windows (but maybe one day cross-platform) Also 2: Resources using alternatives are welcome too... i.e. DirectShow, VFW, etc.

  • How to insert into a table with just one IDENTITY column (SQL Server CE)

    - by Hei
    Hello I am trying to insert a value in a one IDENTITY column Table in SQL Server CE 3.5. I Tried the following: INSERT Target DEFAULT VALUES INSERT Target (ID) VALUES (DEFAULT) INSERT Target (ID) VALUES () But none of them worked. This is the SQL command I used to create the table (Using SQL Server Management Studio): CREATE TABLE Target( ID int NOT NULL IDENTITY (1, 1) PRIMARY KEY ); Microsoft help site (http://msdn.microsoft.com/en-us/library/ms174633%28SQL.90%29.aspx) mentions that DEFAULT values are not valid for identity columns however they do not mention any alternative. They mention something about uniqueidentifier and ROWGUID but I have not been able to make it work. I would appreciate any pointers on how to solve this problem or links to documentation about valid sql commands for sql server CE. Thank you

  • Which Java MVC frameworks integrate easily with StringTemplate?

    - by Daniel Jomphe
    It's hard to see how StringTemplate integrates easily (or not) with popular Java web MVC frameworks. Which Java MVC frameworks integrate easily with StringTemplate? A good answer: mentions one solution to integrate with a framework, includes a link to something useful and applicable, like: a tutorial, or documentation, or a reference to source code: free, and open source or public domain. Readers/Voters, please vote for a solution if you know it's true and great. In the scope of this question, I am not interested in any other templating engine than StringTemplate.

  • SRAM Cell Diagram - Can someone explain this a bit more clearly? ( From COMP1917 @ UNSW: Lecture 2 o

    - by Kristina
    I've begun watching a series of first year lectures from the University of New South Wales (UNSW) in Australia, and I'm a bit perplexed by the instructors explanation of how an SRAM gate works. I realize this isn't exactly "programming-related" but since it comes from a series of lectures relating to computing and programming, I thought StackOverflow may be able to help (reddit failed me entirely). In this lecture beginning at around 32:12, Richard (the lecturer) tries to explain how a "latch gate" works within SRAM. Although his students seem to keep up, I feel I'm missing something crucial which is preventing the concept from really "clicking" in my brain. For convenience, I've added the image from the video below: Thanks in advance for any help you can provide, but if this question doesn't fit your view of "programming-related" could you please provide an alternate forum for this in a comment when you cast your close vote? Thanks!

  • Using adaptive step sizes with scipy.integrate.ode

    - by Mike
    The (brief) documentation for scipy.integrate.ode says that two methods (dopri5 and dop853) have stepsize control and dense output. Looking at the examples and the code itself, I can only see a very simple way to get output from an integrator. Namely, it looks like you just step the integrator forward by some fixed dt, get the function value(s) at that time, and repeat. My problem has pretty variable timescales, so I'd like to just get the values at whatever time steps it needs to evaluate to achieve the required tolerances. That is, early on, things are changing slowly, so the output time steps can be big. But as things get interesting, the output time steps have to be smaller. I don't actually want dense output at equal intervals, I just want the time steps the adaptive function uses.

  • C# template engine

    - by me
    Hi! I am looking for a stand-alone, easy to use from C# code, template engine. What I want to do is create an html and xml files with placeholders for data, and fill them with data from my code. The engine needs to support loops (duplicating parts of the template form more that one object) and conditions (add parts of the template to the final html/xml only if some conditions are true). Can someone recommend a good option for me, and add a link to more-or-less such code sample, and some documentation about how to use the recommended component for my needs? Thanks:) Just wanted to add one more thing - I also need to use loops to duplicate table rows, or even entire tables (in the html version) and complex elements (in the xml version) Thanks again:)

  • .NET Rectangle Off By 1

    - by roygbiv
    After working with the .NET GDI+ Rectangle object, I've noticed that if I create a rectangle that is X:0 * Y:0 * Width:100 * Height:100, the Right and Bottom properties are set to 100, 100. Shouldn't this be 99, 99? 0 - 99 is 100 pixels. 0 - 100 is 101 pixels. FWIW, the documentation does say the right is computed by x + width and the bottom is y + height, but is that correct? Perhaps "correct" doesn't matter here as long it's consistent? All I know is that it is somewhat (read... very) annoying!

  • Are frameworks really necessary for beginners/intermediates? (PHP)

    - by ggfan
    I have been programming for around 6months and currently learning PHP/Mysql. I can create basic functionally sites starting from a plain sheet of paper. Is it necessary I use frameworks to create sites? Currently, everything I do is from scratch. I'll borrow codes from old codes, ask people for help, etc. Are frameworks going to help me much more? Is it alright if I put a site public without using a framework? (I have not looked a lot into frameworks, so my knowledge is limited, but I'm just curious)

  • Forking Multiple Apps Under Python Subprocess

    - by noxtion
    Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

  • .htaccess stupid issue

    - by justnoone
    I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

  • Why is BigDecimal.equals specified to compare both value and scale individually?

    - by bacar
    This is not a question about how to compare two BigDecimal objects - I know that you can use compareTo instead of equals to do that, since equals is documented as: Unlike compareTo, this method considers two BigDecimal objects equal only if they are equal in value and scale (thus 2.0 is not equal to 2.00 when compared by this method). The question is: why has the equals been specified in this seemingly counter-intuitive manner? That is, why is it important to be able to distinguish between 2.0 and 2.00? It seems likely that there must be a reason for this, since the Comparable documentation, which specifies the compareTo method, states: It is strongly recommended (though not required) that natural orderings be consistent with equals I imagine there must be a good reason for ignoring this recommendation.

  • Do mini-filter functions need APCs enabled?

    - by botismarius
    Hello, Many Zw* functions that work with files (such as ZwCreateFile) need to be called at PASSIVE_LEVEL with APCs enabled: http://msdn.microsoft.com/en-us/library/ff566424%28VS.85%29.aspx. This is because, internally, I/O operations are asynchronously and the completion of an operation is delivered through an APC (correct me if I'm wrong). However, the documentation for similar functions from a mini-filter (such as FltCreateFile, FltReadFile, etc) does not specify that APCs should be enabled. Is it safe to call FltCreateFile/FltReadFile with APCs disabled? Thanks!

  • getting started with qpid server

    - by London
    I'd like to get started with qpid, can anyone recommend some useful resources/links/code examples for me to study? I'm interested about java implementations?I'd like to create message sender/listener. I've already done messaging with jboss where I send the message to the queue and the listener picks it up from there, what is different with qpid? Is it the same only replacing jboss as a server with qpid or?I'm new to all of this it might sound weird when I ask it. Oh yes similar question: http://stackoverflow.com/questions/1693099/get-started-with-qpid Doesn't really help me much. Any hints would help me a lot. thank you

  • How to launch a program as as a normal user from a UAC elevated installer

    - by KZ
    I'm writing an NSIS installer and the setup program elevates "as administrator" as needed on Windows 7 / vista. I need to run the installed program at the end of the install and don't want to launch it with the same privileges as the installer. The regular NSIS exec commands run the child process with the same permissions as the installer. There is a UAC plugin for NSIS, but the documentation on it isn't great and it seems v. new; I'd prefer not to use that plugin. Ideally, I'm looking for a small .exe I can include that'll launch the target program without UAC elevation. Does this exist? Any other suggestions? Thanks!

  • Java: How can I create good looking class docs with Javadoc?

    - by Cheeso
    I'd like to create HTNML documentation for a Java class library that includes programming guide information - beyond just a class reference code examples in the reference doc collapsible regions I want it to look well-styled. Something like this: I think that Javadoc exposes a doclet API that allows other parties to provide doc generation integrated in Javadoc. Is there a doclet option that I can use (for free) that does something a little nicer than the standard javadoc output? I tried googling for this but no luck. Suggestions?

  • Using NSWindow or NSPanel as "CardLayout"

    - by Leandro
    How guys. I'm not top dev in java, but what I`m really not is cocoa top dev :P I would like to have your assistance to produce a layout with cocoa and IB to work just like the CardLayout in Java. Do you have some idea of how to do it? Thanks for the attention! EDIT: CardLayout: A set of panels ("cards") are designed to compose a "deck of cards".It works like a queue of panels, in which only the first "card" is shown on the interface.I can easily interchange between cards if I want so to modify the interface to the user. I hope I could help you to help me. =)
