  • Capture DDE Data that is being streamed in to a software

    - by user534391
    Hello, I have a trading software that gets data from the internet. I want to capture that tick data. There is one software that has been made by a local develop which is able to do that and it looks like it uses DDE (NDde.dll, NetSQL.dll). I want to write a custom application that does the same. Any pointers how I can check how the data is being streamed and how to capture that data. I don't think it is encrypted, since the other developer would not have been able to decrypt either. I just need to scan how the software is getting the data. Thank you.

  • Easy to use time-stamps in Python

    - by Morlock
    I'm working on a journal-type application in Python. The application basically permits the user write entries in the journal and adds a time-stamp for later querying the journal. As of now, I use the time.ctime() function to generate time-stamps that are visually friendly. The journal entries thus look like: Thu Jan 21 19:59:47 2010 Did something Thu Jan 21 20:01:07 2010 Did something else Now, I would like to be able to use these time-stamps to do some searching/querying. I need to be able to search, for example, for "2010", or "feb 2010", or "23 feb 2010". My questions are: 1) What time module(s) should I use: time vs datetime? 2) What would be an appropriate way of creating and using the time-stamp objects? Many thanks!

  • Grand Central Strategy for Opening Multiple Files

    - by user276632
    I have a working implementation using Grand Central dispatch queues that (1) opens a file and computes an OpenSSL DSA hash on "queue1", (2) writing out the hash to a new "side car" file for later verification on "queue2". I would like to open multiple files at the same time, but based on some logic that doesn't "choke" the OS by having 100s of files open and exceeding the hard drive's sustainable output. Photo browsing applications such as iPhoto or Aperture seem to open multiple files and display them, so I'm assuming this can be done. I'm assuming the biggest limitation will be disk I/O, as the application can (in theory) read and write multiple files simultaneously. Any suggestions? TIA

  • SQL Like question

    - by mike
    Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?

  • Which Win32 API reports the Format preference in the Region and Language control panel?

    - by Integer Poet
    Windows 7 and Windows Vista have a Region and Language control panel which contains a Formats tab which contains a popup menu titled Format. This menu allows the user to select from among many language-oriented sets of number, currency, time, and date formatting preferences regardless of the language of the base system. For example, I could decide I prefer the default currency symbol to be Japanese yen on a US English system. The Windows Contacts application changes its behavior depending on these format preferences. For example, if I select Japanese formatting preferences, Windows Contacts displays and lets me edit phonetic names (AKA "ruby", "yomi", and "furigana") but not middle names. If I select US English formatting preferences, Windows Contacts displays and lets me edit middle names but not phonetic names. I need to write code (native C calling Win32) which mirrors the behavior of the Windows Contacts application in this respect. Which API should I call?

  • Correct sequence of actions when using Markdown & MySQL?

    - by Andrew Heath
    I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

  • How would I UPDATE these table entries with SQL and PHP?

    - by CT
    I am working on an Asset Database problem. I enter assets into a database. Every object is an asset and has variables within the asset table. An object is also a type of asset. In this example the type is server. Here is the Query to retrieve all necessary data: SELECT asset.id ,asset.company ,asset.location ,asset.purchaseDate ,asset.purchaseOrder ,asset.value ,asset.type ,asset.notes ,server.manufacturer ,server.model ,server.serialNumber ,server.esc ,server.warranty ,server.user ,server.prevUser ,server.cpu ,server.memory ,server.hardDrive FROM asset LEFT JOIN server ON server.id = asset.id WHERE asset.id = '$id' I then assign all results into single php variables. How would I write a query/script to update an asset?

  • How do you authenticate user generated "apps" for your app?

    - by Brian Armstrong
    I'm think something like Facebook apps here. User generated pieces of code that people can write to interact with my app. I understand how an authenticated API works, but this seems a little more complicated because not only does the APP have to authenticate itself (with a regular api-key) but the USER using the app has to be authenticated somehow too, without giving the app free reign. I've been reading a bit here to see how FB does it: http://wiki.developers.facebook.com/index.php/How_Facebook_Authenticates_Your_Application And it looks like you have to pass a signature in addition to the api-key along with every call, but I'm having trouble wrapping my head around how this gets generated and used on the other end (my server). Figure there must be a simple explanation of this out there? Thanks! P.S. I'm building a Rails app if there are any applicable gems/plugins.

  • Base64 Android encode to PHP decode make error

    - by studio lambda
    I'm a french guy, so, I'm sorry for my english... I'm developing an Android App which communicate with a PHP REST service. So, when I try to encode an image file into Base64 like this : InputStream fileInputStream = context.getContentResolver().openInputStream(uri); BufferedInputStream in = new BufferedInputStream(fileInputStream); StringWriter out = new StringWriter(); int b; while ((b = in.read()) != -1) out.write(b); out.flush(); out.close(); in.close(); String encoded = new String(android.util.Base64.encode(out.toString() .getBytes(), android.util.Base64.DEFAULT)); On server side, I make : $data=base64_decode(chunk_split($base64BinaryData)); The result is that my image file is corrupted! INFO : the image is made by an Intent to android.provider.MediaStore.ACTION_IMAGE_CAPTURE Activity in Emulator mode (avd 5554) I've already read lots of discussions about similar problem but nothing fix my bug. thanks for help Regards,

  • msxml domdocument stops working when I move to staging server

    - by blockhead
    I have some code that looks like this: Set xmlHttp = Server.CreateObject("MSXML2.ServerXMLHTTP") xmlHttp.Open "Get", myRSSfile, false xmlHttp.Send() myXML = xmlHttp.ResponseText Set xmlResponse = Server.CreateObject("MSXML2.DomDocument") xmlResponse.async = false xmlResponse.LoadXml(myXML) Set xmlHttp = Nothing Set objLst = xmlResponse.getElementsByTagName("item") Set xmlResponse = Nothing NoOfHeadlines = objLst.length - 1 Response.Write NoOfHeadlines This worked find on my development server. When I moved it over to a staging server (which I have no control over, and no nothing about), NoOfHeadlines returns 0. It seems obvious to me that DomDocument is not working the way its supposed to. Is this a version issue? How do I find out what version of DomDocument is on the staging server? Is there another possibility?

  • bash script to delete old deployments

    - by benjwarner
    I have a directory where our deployments go. A deployment (which is itself a directory) is named in the format: <application-name>_<date> e.g. trader-gui_20091102 There are multiple applications deployed to this same parent directory, so the contents of the parent directory might look something like this: trader-gui_20091106 trader-gui_20091102 trader-gui_20091010 simulator_20091106 simulator_20091102 simulator_20090910 simulator_20090820 I want to write a bash script to clean out all deployments except for the most current of each application. (The most current denoted by the date in the name of the deployment). So running the bash script on the above parent directory would leave: trader-gui_20091106 simulator_20091106 Any help would be appreciated.

  • What's the best self-tracking software for Linux?

    - by trench
    I'm looking for a way to track myself and receive quality data upon which I can write future scripts/programs. For example, I use Google Reader a lot. I'd like to track the hrefs that garner my clicks. Further, I'd like to drop all of the words of each href into a database where they can be stacked in a hierarchical manner. At the end of the week I want to know that "Ubuntu" garnered 448 clicks and "Cheetos" garnered 2. :) That's just one example... I'd like this tracking and data-collecting to extend beyond my browser. I know writing something to do this myself wouldn't be too awfully difficult but if something already exists I'd happily use it. Thanks in advance. Primary OS: Ubuntu 10.04

  • Validate a string in a table in SQL Server

    - by Ashish Gupta
    I need to check If a column value (string) in SQL server table starts with a small letter and can only contain '_', '-', numbers and alphabets. I know I can use a SQL server CLR function for that. However, I am trying to implement that validation using a scalar UDF and could make very little here...I can use 'NOT LIKE', but I am not sure how to make sure I validate the string irrespective of the order of characters or in other words write a pattern in SQL for this. Am I better off using a SQL CLR function? Any help will be appreciated.. Thanks in advance

  • Key logging in .NET

    - by Moshe
    Is it possible to write a key logger in Visual Basic.NET? Is this the right language to be using? So far, I've gotten a console app to read input and append to a file. 1)How can I make a .NET program "catch" all keyboard input? 2)How do I make a process not show up in Task Manager? This is not for a virus, but rather a parental control program for a specific clientele. No malicious intent here.

  • Multithreading in Lua

    - by RCIX
    I was having a discussion with my friend the other day. I was saying how that, in pure Lua, you couldn't build a preemptive multitasking system. He claims you can, because of the following reason: Both C and Lua have no inbuilt threading libraries [OP's note: well, Lua technically does, but AFAIK it's not useful for our purposes]. Windows, which is written in mostly C(++) has pre-emptive multitasking, which they built from scratch. Therefore, you should be able to do the same in Lua. The big problem i see with that is that the main way preemptive multitasking works (to my knowledge) is that it generates regular interrupts which the manager uses to get control and determine what code it should be working on next. I also don't think Lua has any facility that can do that. My question is: is it possible to write a pure-Lua library that allows people to have pre-emptive multitasking?

  • Regex Searching in Emacs

    - by Inaimathi
    I'm trying to write some Elisp code to format a bunch of legacy files. The idea is that if a file contains a section like "<meta name=\"keywords\" content=\"\\(.*?\\)\" />", then I want to insert a section that contains existing keywords. If that section is not found, I want to insert my own default keywords into the same section. I've got the following function: (defun get-keywords () (re-search-forward "<meta name=\"keywords\" content=\"\\(.*?\\)\" />") (goto-char 0) ;The section I'm inserting will be at the beginning of the file (or (march-string 1) "Rubber duckies and cute ponies")) ;;or whatever the default keywords are When the function fails to find its target, it returns Search failed: "[regex here]" and prevents the rest of evaluation. Is there a way to have it return the default string, and ignore the error?

  • Unit testing "hybrid" WPF/Silverlight controls

    - by Alan Mendelevich
    I'm starting a new WPF/Silverlight custom control project and wanted to do unit testing on this one. However I'm a little confused about how to approach this. This control would be based on the same codebase for both WPF and Silverlight with minor forking using #ifs and partial classes to tame the differences. I guess I could write unit tests for WPF part with NUnit, MSTest, xUnit, etc. and for the Silverlight part with Silverlight Unit Test Framework but this doesn't sound very elegant to me. I'd have to either ignore testing identical code on one of the platforms and test only differing parts (which is not very trustworthy) or rewrite tests for 2 frameworks (which is annoying). Is this the right way to go? I'm wondering if there's some guidance, articles, tutorials out there on how to approach this task. Any pointers?

  • F#: any way to use member functions as unbound functions?

    - by gatoatigrado
    Is there a way to extract member functions, and use them as F# functions? I'd like to be able to write the following: mystring |> string.Split '\n' |> Array.filter (string.Length >> (=) 0 >> not) The code above works if you [let] let mystring = "a c\nb\n" let stringSplit (y:char) (x:string) = x.Split(y) let stringLength (x:string) = x.Length mystring |> stringSplit '\n' |> Array.filter (stringLength >> (=) 0 >> not)

  • Reading numeric Excel data as text using xlrd in Python

    - by Brian
    Hi guys, I am trying to read in an Excel file using xlrd, and I am wondering if there is a way to ignore the cell formatting used in Excel file, and just import all data as text? Here is the code I am using for far: import xlrd xls_file = 'xltest.xls' xls_workbook = xlrd.open_workbook(xls_file) xls_sheet = xls_workbook.sheet_by_index(0) raw_data = [['']*xls_sheet.ncols for _ in range(xls_sheet.nrows)] raw_str = '' feild_delim = ',' text_delim = '"' for rnum in range(xls_sheet.nrows): for cnum in range(xls_sheet.ncols): raw_data[rnum][cnum] = str(xls_sheet.cell(rnum,cnum).value) for rnum in range(len(raw_data)): for cnum in range(len(raw_data[rnum])): if (cnum == len(raw_data[rnum]) - 1): feild_delim = '\n' else: feild_delim = ',' raw_str += text_delim + raw_data[rnum][cnum] + text_delim + feild_delim final_csv = open('FINAL.csv', 'w') final_csv.write(raw_str) final_csv.close() This code is functional, but there are certain fields, such as a zip code, that are imported as numbers, so they have the decimal zero suffix. For example, is there is a zip code of '79854' in the Excel file, it will be imported as '79854.0'. I have tried finding a solution in this xlrd spec, but was unsuccessful.

  • Ruby Socket Inheritance

    - by Jarsen
    I'm writing a Ruby class that extends TCPSocket. Assume it looks something like this: class FooSocket < TCPSocket def hello puts 'hello' end end I have a TCPServer listening for incoming connections server = TCPServer.new 1234 socket = server.accept When my server finally accepts a connection, it will return a TCPSocket. However, I want a FooSocket so that I can call socket.hello. How can I change TCPSocket into a FooSocket? I could duck-punch the methods and attributes I want directly onto the TCPSocket class, but I'm using it elsewhere and so I don't want to do that. Probably the easiest solution is to write a class that encapsulates a TCPSocket, and just pass the socket returned by accept as a param. However, I'm interested to know how to do it through inheritance—I've been trying to bend my mind around it but can't figure it out. Thanks in advance.

  • SQL for selecting only the last item from a versioned table

    - by Jeremy
    I have a table with the following structure: CREATE TABLE items ( id serial not null, title character varying(255), version_id integer DEFAULT 1, parent_id integer, CONSTRAINT items_pkey PRIMARY KEY (id) ) So the table contains rows that looks as so: id: 1, title: "Version 1", version_id: 1, parent_id: 1 id: 2, title: "Version 2", version_id: 2, parent_id: 1 id: 3, title: "Completely different record", version_id: 1, parent_id: 3 This is the SQL code I've got for selecting out all of the records with the most recent version ids: select * from items inner join ( select parent_id, max(version_id) as version_id from items group by parent_id) as vi on items.version_id = vi.version_id and items.parent_id = vi.parent_id Is there a way to write that SQL statement so that it doesn't use a subselect?

  • Chipmunk warning still present with --release

    I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

  • Django DecimalField returns "None" instead of empty value

    - by Ed
    Is there a way to force django to display nothing instead of "None" for a Decimal Field that's been left blank? In my template, I show a list of all the values for a particular field. Each value is hyperlinked to a page that displays the results of a query filtered on that value. But because there are some entries with null value, my list includes actual DecimalField entries and "None" for all those that are empty. When a user clicks on None, django throws a validation error because you cannot query a DecimalField using a string. I could write if statements checking all instances of decimal fields for Nones and skipping them, but that is far from an elegant solution. Any advice? This is one part of the code, though there are other templates that derive the None value in slightly different manners: {% for item in choices %} <a href={% url app_views.field_choice item %}>{{ item }}</a><br> {% endfor %}
