  • Powershell equivilent of python's if __name__ == '__main__':

    - by Mark Mascolino
    I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

  • sqlplus remove \r \n \t from spool

    - by Tom
    Hi all, Is there any sql*plus command to remove \r \n and\t from the result set that's going out to the spool file? That is, "trim" every record? We've used set trim on in the past, but it doesn't seem to bue what we need right now. I'm trying to avoid calling oracle's translate, chr functions in the sql query. For example, If my query returns this |DATA| |\n \t\t\t\t\t thisistheactualdata \t\t\t\t\t\t\n| I'd like to keep this |DATA| |thisistheactualdata| Thanks in advance.

  • C# convert integer to hex and back again

    - by codette
    How can I convert the following? 2934 (integer) to B76 (hex) Let me explain what I am trying to do. I have User IDs in my database that are stored as integers. Rather than having users reference their IDs I want to let them use the hex value. The main reason is because it's shorter. So not only do I need to go from integer to hex but I also need to go from hex to integer. Is there an easy way to do this in C#?

  • Best solution for language documentation.

    - by Simone Margaritelli
    I'm developing a new object oriented scripting language and the project itself is quite ready for audience now, so i'm starting to think about a serious (not as "drafty" as it is right now) way of document its grammar, functions from standard library and standard library classes. I've looked a bit around and almost every language hash its own web application for the documentation, Python uses Sphinx for instance. Which is the best PHP (don't have the time/will to install mod_who_knows_what on my server) application to accomplish this? I've used mediawiki a bit but i found its tag system a little bit hard to use in this context. Thanks for your answers.

  • How to configure a has_many association with non-ActiveRecord model

    - by Callmeed
    My Rails app has a normal ActiveRecord "Account" model stored in the database. The model will store the URL to a remote XML file which defines some other objects. For example, the Account has_many :galleries but the Gallery model is simply defined by nodes in the XML document. So how do I get /accounts/1/galleries to show the galleries from that account's XML? How do I setup this relationship? I know how to do basic non-AR models, but I'm not sure how to define the association or if I need to create a Gallery model at all.

  • When a template is rendered in template tag code, MEDIA_URL is not in context

    - by culebrón
    I want to use a template for 2 template tags. In the template, I used {{ MEDIA_URL }} and discovered that MEDIA_URL is not in context as expected. Had to use get_config and pass it manually. Why is the setting not in context, how else can I put it there, or maybe there's a better way that a template tag? (include, etc?) from django.template import Library from apps.annoying.functions import get_config from django.template.loader import render_to_string register = Library() @register.simple_tag def next_in_gallery(photo, gallery): next = photo.get_next_in_gallery(gallery) return make_arrow('right', next) @register.simple_tag def previous_in_gallery(photo, gallery): prev = photo.get_previous_in_gallery(gallery) return make_arrow('left', prev) def make_arrow(direction, object): return render_to_string('myapp/arrow.html', {'direction': direction, 'object': object, 'MEDIA_URL': get_config('MEDIA_URL', '')})

  • Idiomatic approach for structuring Clojure source code

    - by mikera
    I'm interested in how people structure their Clojure source code. Being used to Java, I'm pretty familiar with the paradigm of one class per source code file, bundling all the data and method definitions with appropriate comments and annotations etc. However Clojure offers a lot more flexibility, and I'm not sure how I should structure my project (likely to end up as a medium sized app, maybe 5,000 lines with three or four distinct subsystems) In particular I'm wrestling with: What guidelines should I use to determine whether code should be in a single namespace vs. separated out into different namespaces? Should each protocol/datatype have it's own namespace + source file with associated set of functions? When should I require vs. use other namespaces?

  • Breaking the SQL Compact 8K Limit?

    - by David Veeneman
    I am creating a desktop application that stores rich text documents to a SQL Compact database. Documents are converted to a byte array and stored as a Binary column, and I am running into SQL Compact's 8K limit for Binary field length. Is there a simple way to get around the 8K limit? I can come up with lots of complicated ways to do it, such as parsing into 8K chunks for storage and reassembling on fetch. But before I get into something that complex, I would like to make sure I can't solve the problem more simply, such as by changing data type. If there is no simple way of getting around the 8K limit, is thare a best practice for storing documents greater than 8K? Thanks for your help.

Is there a validator to check the GMarker is nice and clean? google maps main.js throws a wobbly: Uncaught TypeError: Cannot read property '__e_' of undefined

  • HTA value update freezes when file copy starts

    - by Matt Hamende
    Creating an HTA that will automate the installation of several applications it starts by checking for the existence of certain files then copies a large folder to local from a flash drive if it doesn't exist, I have a textbox I'm using to update the current status of the script, but it just seems to freeze and never updates, I haven't had any luck with any of the artificial sleep functions either. here's the segment If Not objFSO.FileExists(Office10Dir) Then MsgBox("Excel is missing") BasicTextBox.Value = "Office14 Not Detected, Copying Source Files to Local" Dim objFS, objFolder Dim OfficeTemp OfficeTemp = "C:\OfficeTemp" Set objFS = CreateObject("Scripting.FileSystemObject") Set objFolder = objFS.CreateFolder(OfficeTemp) objFS.CopyFolder "OfficeTemp", "C:\OfficeTemp" BasicTextBox.Value = "Local Temp Directory Created" ELSE MsgBox("Excel is Installed") END IF All i see is the "Local Temp Directory Created" message once file copy is complete

  • What is the easiest way to loop through a folder of files in C#?

    - by badpanda
    I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

  • How do Ruby and Python implement their interactive consoles?

    - by sxa
    When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share" the code? How is the code entered handled? Example: >> def x: >> print("Blah") >> >> x() Where is the function stored so it can be called at any time again? How can the interactive console take everything entered as obviously one program without executing everything over and over again?

  • Avoid the use of loops (for) with R

    - by albergali
    Hi, I'm working with R and I have a code like this: i<-1 j<-1 for (i in 1:10) for (j in 1:100) if (data[i] == paths[j,1]) cluster[i,4] <- paths[j,2] where : data is a vector with 100 rows and 1 column paths is a matrix with 100 rows and 5 columns cluster is a matrix with 100 rows and 5 columns My question is: how could I avoid the use of "for" loops to iterate through the matrix? I don't know whether apply functions (lapply, tapply...) are useful in this case. This is a problem when j=10000 for example, because execution time is very long. Thank you

  • Conditional type definitions

    - by pythonic metaphor
    I'm sure that boost has some functions for doing this, but I don't know the relevant libraries well enough. I have a template class, which is pretty basic, except for one twist where I need to define a conditional type. Here is the psuedo code for what I want struct PlaceHolder {}; template <typename T> class C{ typedef (T == PlaceHolder ? void : T) usefulType; }; How do I write that type conditional?

  • Other SecurityManager implementations available?

    - by mhaller
    Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

  • How can I use MVC ideas without using classes?

    - by jpjp
    As of right now, I am still shaky on classes, so I don't want to use any classes for my site. I'm still practicing with classes. But how can I implement the MVC idea without classes? Would this work for a MVC? index.php (the view) index_controller.php index_model.php Is this right for what a MVC should be? View: show html, css, forms Controller: get $_POST from forms and any data from the user, get info from db Model: do all the functions, insert/delete in db, etc Basically separate the HTML/css for the view, all the data collecting for the controller, and the logic for the model. And just connect them all using require_once.

  • Capturing stdout within the same process in Python

    - by danben
    I've got a python script that calls a bunch of functions, each of which writes output to stdout. Sometimes when I run it, I'd like to send the output in an e-mail (along with a generated file). I'd like to know how I can capture the output in memory so I can use the email module to build the e-mail. My ideas so far were: use a memory-mapped file (but it seems like I have to reserve space on disk for this, and I don't know how long the output will be) bypass all this and pipe the output to sendmail (but this may be difficult if I also want to attach the file)

  • Service-Based Authentication Using Tokens

    - by jerhinesmith
    I'm having a tough time trying to find clear and concise examples of how one would implement a service-based authentication scheme using tokens. As far as I can tell, the basic steps are as follows: Client requests username/password from user Client passes username/password to identity provider Provider checks username/password and sends back a token if the user is valid Client does something with the token? The third and fourth step are where I'm getting stuck. I assume the "token" in this case just has to be either an encrypted string that the client can decrypt or some random string that gets stored somewhere (i.e. a database) that the client can then verify against, but I'm not really sure what the client is then supposed to do with the token or why you even need a token at all -- couldn't a simple user ID also suffice?

  • Set a js variable in a html include

    I have a ASP.NET page that uses the include method for header. I am adding a JS variable that I access from JS functions In head.htm <script language="javascript" type="text/javascript"> var render=<%= RenderProperty %>; </script> The RenderProperty is a method in the base page class (a .cs file that inherits from System.Web.UI.Page) It looks something like this: private bool _renderProp = false; public bool RenderProperty { get { return _renderProp; } set { _renderProp = value; } } On a page by page basis, I set the RenderProperty in the Page_Load of a aspx page protected void Page_Load(object sender, EventArgs e) { RenderProperty = true; } I get a compile time error that says: The name 'RenderProperty' does not exist in the current context C:\...\head.htm

  • Jquery - How to make $.post() use contentType=application/json?

    - by JK.
    I've noticed that when using $.post() in jquery that the default contentType is application/x-www-form-urlencoded - when my asp.net mvc code needs to have contentType=application/json (See this question for why I must use application/json: http://stackoverflow.com/questions/2792603/aspnet-mvc-why-is-modelstate-isvalid-false-the-x-field-is-required-when-that) How can I make $.post() send contentType=application/json? I already have a large number of $.post() functions, so I don't want to change to $.ajax() because it would take too much time If I try $.post(url, data, function(), "json") It still has contentType=application/x-www-form-urlencoded. So what exactly does the "json" param do if it does not change the contenttype to json? If I try $.ajaxSetup({ contentType: "application/json; charset=utf-8" }); That works but affects every single $.get and $.post that I have and causes some to break. So is there some way that I can change the behavior of $.post() to send contentType=application/json?

  • WPF - How do I style a row based on a binding property value?

    - by Nick
    Hey! So I am trying to bind a collection of objects (IList<) to a WPF datagrid. I would like to make the row background a different color if the 'artist' property is null or empty. I am checking the value stored at the property on the LoadingRow datagrid event. Currently my implementation seems to style all of the rows with an empty or null 'artist' property correctly. The problem is that is also styles the rows where the property is not null or empty in some cases. So some rows are given the red background even though the rows 'artist' property is not null. Can anyone tell me why this could be?? Here is the LoadingRow event: private void trackGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Track t = e.Row.DataContext as Track; if (String.IsNullOrEmpty(t.Artist)) { e.Row.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 125, 125)); } }

  • Convert VB6 Randomize to C#

    - by Thomas G. Mayfield
    I'm writing a C# frontend to a legacy database that uses VB6 Rnd() and Randomize() methods for user password encryption. The encryption function is very simplistic and really not all that secure, but it's what all current passwords are stored with. What I'd like to be able to do is authenticate legacy users from a C# application. I can write new encryption (or preferably hashing) code for VB6 so that all future users have a more secure password, and that can be duplicated in C#. But I don't want to require current users to have had their password reset before they can use the new frontend. Is there any way I can reimplement that algorithm in C# so that it produces identical results to the legacy VB6 code?

  • Python: Unpack arbitary length bits for database storage

    - by sberry2A
    I have a binary data format consisting of 18,000+ packed int64s, ints, shorts, bytes and chars. The data is packed to minimize it's size, so they don't always use byte sized chunks. For example, a number whose min and max value are 31, 32 respectively might be stored with a single bit where the actual value is bitvalue + min, so 0 is 31 and 1 is 32. I am looking for the most efficient way to unpack all of these for subsequent processing and database storage. Right now I am able to read any value by using either struct.unpack, or BitBuffer. I use struct.unpack for any data that starts on a bit where (bit-offset % 8 == 0 and data-length % 8 == 0) and I use BitBuffer for anything else. I know the offset and size of every packed piece of data, so what is going to be the fasted way to completely unpack them? Many thanks.
