  • Starting a VC++ .exe from MSAccess

    - by Pieter_Jack
    For a complex calculating problem we use an VC++ module (.exe). For the users we have build an ms Access application as userinterface. After input dthe calculating module should start and do its job. The result is again imported in Ms Access. However we work wit dBase files (.dbf) as datafiles. The calculating unit works fine by its own, but when access is running it wo'nt do its job. It will start-up when called from the Access module, but then generates errors or at least does not write correct results to a datatable. We cannot find the reason for this beheavior. Can anyone give us a tip?

  • Integrating virtual keyboard on a HP TouchSmart with an Adobe AIR app

    - by Alan
    Hi, Does anyone know if it's possible to integrate the ToushSmart's virtual keyboard with an Adobe AIR application? In most programs (Internet Explorer, Firefox, etc), when a user touches a text field a little keyboard icon automatically pops up which, when pressed, will bring up the virtual keyboard. However, this doesn't happen when clicking on text input fields in Adobe AIR applications. Has anyone had any experience working with AIR/Flash and touchscreens? Is there any API that can tell Windows (or the HP virtual keyboard specifically) that the user has clicked in a text field and that the virtual keyboard should be shown? The text fields are the standard kind (fl.controls.TextInput). Any suggestions would be greatly appreciated. Thanks in advance!

  • Super wide, but not so tall, bitmap?

    - by Erik Karlsson
    Howdy folks. Is there any way to create a more space/resource efficient bitmap? Currently i try to render a file, approx 800 px high but around 720000px wide. It crashes my application, presumebly because of the share memory-size of the bitmap. Can i do it more efficient, like creating it as an gif directly and not later when i save it? I try to save a series of lines/rectangles from a real world reading, and i want it to be 1px per 1/100th of a second. Any input? And btw, i never manage to ogon using google open id : /

  • iPhone: Having trouble figuring out how to scroll a UITableView with custom UITextField cells automa

    - by Gordon Fontenot
    Ok, I know this seems like a duplicate question, but don't think it is. I actually have this implemented already (thanks to this SO question), but it seems sluggish. I am willing to tweak it a bit, but I ran across a demo app by AboutObjects that seems to have exactly the right functionality with absolutely no code doing it. I have looked through their demo code dozens of times, and I can't figure out what they are doing that I am not. The code to look at is in their iPhone Development Tutorials section, and is called "Editable TableView" (2nd from the bottom). There are a couple of questions on the forums on that site asking how they got the functionality, but there is no answer (other than "It's a built in function"). Does anyone have any clue as to why their UITableView would implement the input scrolling by default (including being able to scroll the view manually when the keyboard pops up, which I cannot get to work)?

  • Is there anything for Python that is like readability.js?

    - by Emre Sevinç
    Hi, I'm looking for a package / module / function etc. that is approximately the Python equivalent of Arc90's readability.js http://lab.arc90.com/experiments/readability http://lab.arc90.com/experiments/readability/js/readability.js so that I can give it some input.html and the result is cleaned up version of that html page's "main text". I want this so that I can use it on the server-side (unlike the JS version that runs only on browser side). Any ideas? PS: I have tried Rhino + env.js and that combination works but the performance is unacceptable it takes minutes to clean up most of the html content :( (still couldn't find why there is such a big performance difference).

  • Tricking a Unix Commandline Program into Accepting a File Stream

    - by Alan Storm
    Hypothetical situation. I have a command line program in *nix (linux, BSD, etc.). It was written so that you pass it a text file as an argument $ program file.txt Run the program, it looks at the text in file.txt. Is it possible to "trick" this program into accepting input from a file stream rather than reading a file via disk? I'm pretty comfortable using unix pipes to do stuff, but there's still something a little mysterious about their internals that make it so I can't say (definitively) yes or not to the above question.

  • How do I add a click handler to a new element when I create it? [closed]

    - by vicky
    How do I add a click handler to a new element when I create it? This is what I have tried, but it does not work as expected: DeCheBX = $('MyDiv').insert(new Element('input', { 'type': 'checkbox', 'id': "Img" + obj[i].Nam, 'value': obj[i].IM, 'onClick': SayHi(this) })); document.body.appendChild(DeCheBX); DeImg = $('MyDiv').insert(new Element('img', { 'id': "Imgx" + obj[i].Nam, 'src': obj[i].IM })); document.body.appendChild(DeImg); } SayHi = function (x) { try { if ($(x).checked == true) { alert("press" + x); } } catch (e) { alert("error");

  • IVR-style dialog system / workflow / menu

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • Spring WS & Validator interceptor

    - by mada
    I have a endpoint mapping a webservice which is used to insert in the dabatabase some keywords: @Transactional(readOnly = false,isolation= Isolation.SERIALIZABLE) public Source saveKW(...). The input is a request. I would like to add an interceptor on the method in order to validate the parameters. this one will read some values from the DB. i would like that this interceptor is EMBED in the transaction declared for the endpoint (or this opposite). In other words, i want them to be in the same transaction. Ideally im looking for something like this with annotation: @Transactional(readOnly = false,isolation= Isolation.SERIALIZABLE) @validator("KeyWordValidaor.class") public Source saveKW(...) where KeyWordValidaor will be class validating the parameters. Have you any idea or short examples to implements this like this way or in a other real way?

  • Options for non-native form inputs for the web?

    - by Sam Lee
    I'm wondering if there are any good non-native form inputs for web development? I am currently using the built in <input> controls. They work just fine, but for my application they are too big (especially on OS X). I am wondering if there are any libraries that I can drop in as replacements. I am especially interested in ones that: Are a close to native control behavior as possible. Support for tabbing, highlighting current textbox, pressing up/down in <select>, etc. Have something that replicates <select> Look good and are compact I am aware that you can use CSS for some styling, but it's pretty minimal and looks different depending on the browser. Thanks for your help.

  • .Net Process keep command window open

    - by msarchet
    right now I am working on a tool that does a lot of work via the Process object through the command line. So there are times when I want the command window to not show up and times when I want it to stay open so that the user can see what happened, possibly respond with the appropriate input. Dim pro As New Process pro.StartInfo.WorkingDirectory = path pro.StartInfo.Arguments = command pro.StartInfo.FileName = "hg" pro.StartInfo.RedirectStandardOutput = True If command.Contains("-q") Then pro.StartInfo.UseShellExecute = False pro.StartInfo.CreateNoWindow = True pro.StartInfo.WindowStyle = ProcessWindowStyle.Hidden End If pro.Start() pro.WaitForExit() Return pro.StandardOutput.ReadToEnd The flag that I am checking in the command is for a -q if it doesn't contain this I would like to show the command prompt to the user and wait for them to close it. Is this possible and if so what am I missing?

  • Visualizing an AST created with ANTLR (in a .Net environment)

    - by Benjamin Podszun
    Hi there. For a pet project I started to fiddle with ANTLR. After following some tutorials I'm now trying to create the grammar for my very own language and to generate an AST. For now I'm messing around in ANTLRWorks mostly, but now that I have validated that the parse tree seems to be fine I'd like to (iteratively, because I'm still learning and still need to make some decisions regarding the final structure of the tree) create the AST. It seems that antlrworks won't visualize it (or at least not using the "Interpreter" feature, Debug's not working on any of my machines). Bottom line: Is the only way to visualize the AST the manual way, traversing/showing it or printing the tree in string representation to a console? What I'm looking for is a simple way to go from input, grammar - visual AST representation a la the "Interpreter" feature of ANTLRWorks. Any ideas?

  • Portable applications for phones?

    - by peoro
    What's the best way to write an application in order to get it working on the several phones out there (iPhone, symbian-based, xpPhone, and so on)? The idea I have in mind is that of writing a few interfaces to abstract from phone-dependent stuff (ie: some Input/Output interfaces), implementing such interfaces on the several phones and then writing an application that doesn't use any phone-dependent thing. But is this really possible? What would be the language I should choose for my interfaces and applications? (would love to use C++, hopefully even with GCC extensions) Is there any project that aims to offer what I need? (maybe something like SDL?)

  • Piping SoX in Python - subprocess alternative?

    - by Cochise Ruhulessin
    I use SoX in an application. The application uses it to apply various operations on audiofiles, such as trimming. This works fine: from subprocess import Popen, PIPE kwargs = {'stdin': PIPE, 'stdout': PIPE, 'stderr': PIPE} pipe = Popen(['sox','-t','mp3','-', 'test.mp3','trim','0','15'], **kwargs) output, errors = pipe.communicate(input=open('test.mp3','rb').read()) if errors: raise RuntimeError(errors) This will cause problems on large files hower, since read() loads the complete file to memory; which is slow and may cause the pipes' buffer to overflow. A workaround exists: from subprocess import Popen, PIPE import tempfile import uuid import shutil import os kwargs = {'stdin': PIPE, 'stdout': PIPE, 'stderr': PIPE} tmp = os.path.join(tempfile.gettempdir(), uuid.uuid1().hex + '.mp3') pipe = Popen(['sox','test.mp3', tmp,'trim','0','15'], **kwargs) output, errors = pipe.communicate() if errors: raise RuntimeError(errors) shutil.copy2(tmp, 'test.mp3') os.remove(tmp) So the question stands as follows: Are there any alternatives to this approach, aside from writing a Python extension to the Sox C API?

  • Big O complexity of simple for not always linear?

    - by i30817
    I'm sure most of you know that a nested loop has O(n^2) complexity if the function input size is n for(int i = 0; i < n; i++){ for(int j = 0; j < n; j++){ ... } } I think that this is similar, by a analogous argument, but i'm not sure can anyone confirm? for(int i = 0, max = n*n; i < max; i++{ ... } If so i guess that there is some kinds of code whose big O mapping is not immediately obvious besides recursion and subroutines.

  • problem using base64 encoder and InputStreamReader

    - by karoberts
    I have some CLOB columns in a database that I need to put Base64 encoded binary files in. These files can be large, so I need to stream them, I can't read the whole thing in at once. I'm using org.apache.commons.codec.binary.Base64InputStream to do the encoding, and I'm running into a problem. My code is essentially this FileInputStream fis = new FileInputStream(file); Base64InputStream b64is = new Base64InputStream(fis, true, -1, null); InputStreamReader reader = new InputStreamReader(b64is); preparedStatement.setCharacterStream(1, reader); When I run the above code, I get one of these during the execution of the update java.io.IOException: Underlying input stream returned zero bytes, it is thrown deep in the InputStreamReader code. Why would this not work? It seems to me like the reader would attempt to read from the base 64 stream, which would read from the file stream, and everything should be happy.

  • Problem on IE6-8 with jQuery

    - by Alain Fontaine
    Hello guys, I'm stuck here with this IE6 issue.. always a pain. So I'm using jQuery's "live" feature to add a product each time. Then once each dropdown's value is changed, an input field assigned to it changes its value too so when I hit submit, it sends all the info. Everything works perfectly fine except in IE6, IE7, and IE8. I have no idea why... I've gone through the code and everything... so please guys. Help! :) These are all the files: Index.php http://pastie.org/967139 Submit.php http://pastie.org/967140 JS http://pastie.org/967141 Please guys, I'm really stuck here. I would appreciate some help.

Inside the partial view i have this: <%=Html.TextBox("instance.Id", Model.Id)%> when i put a breakpoint here over Model.Id it has a number in it but after the ajax refresh is done the textbox just shows up with a 0. When i do a full browser refresh, the correct number shows up in the textbox. when i use firebug to look at data in my callback i see this: <input id="instance_Id" name="instance.Id" type="text" value="0" /> Everything else in the partial view refreshes fine. any ideas on what could be going wrong here?

  • Convert json to a string using jquery

    - by becomingGuru
    I have a nested json. I want to post it as a form input value. But, seems like jquery puts "Object object" string into the value. It seems easier to pass around the string and convert into the native form I need, than dealing with json as I don't need to change anything once it is generated. What is the simplest way to convert a json var json = { "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }; into its string form? var json = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ], "newSubscription": false, "companyName": null }' Following doesn't do what I need: Json.stringify()

  • Why is this an invalid Turing machine?

    - by Danny King
    Whilst doing exam revision I am having trouble answering the following question from the book, "An Introduction to the Theory of Computation" by Sipser. Unfortunately there's no solution to this question in the book. Explain why the following is not a legitimate Turing machine. M = { The input is a polynomial p over variables x1, ..., xn Try all possible settings of x1, ..., xn to integer values Evaluate p on all of these settings If any of these settings evaluates to 0, accept; otherwise reject. } This is driving me crazy! I suspect it is because the set of integers is infinite? Does this somehow exceed the alphabet's allowable size? Thanks!

  • loading data from file into 2d array

    - by Chris
    I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris
