  • Android: Enable selection in webkit

    - by tacone
    Hello, I'am looking for a way to have a webview content selectable in the very same way as the stock browser does. user long presses the text the whole word is selected two pins appear at the word's boundary allowing the user to stretch/shrink the selection. I should note that Dolphin HD shows exactly the same text select functionality as the default browser (same icons, animation, etc), so it really should be possible. But I can't figure out how. Until now, all i found was this function, which kind of work, but doesn't allow the user to expand/shrink the selection. public void selectAndCopyText() { try { KeyEvent shiftPressEvent = new KeyEvent(0,0,KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0); shiftPressEvent.dispatch(mWebView); } catch (Exception e) { throw new AssertionError(e); } }

  • Javascript cross-domain web request fails with Status=0?

    - by Tav
    Yes, I know the following code does not work in IE. I know IE expects me to use XDomainRequest() instead. I don't care about that. This is firefox only. I'm trying to do a cross-domain web request in firefox javascript. I keep getting a status of 0. Does anyone know why? var url = "http://newyork.craigslist.org"; var xdr = new XMLHttpRequest(); //Yes, I know IE expects XDomainRequest. Don't care xdr.onreadystatechange = function() { if (xdr.readyState == 4) { alert(xdr.status); //Always returns 0! And xdr.responseText is blank too } } xdr.open("get", url, true); xdr.send(null); Shouldn't that work?

  • c printing string syntax

    - by user535256
    Hello guys, Just stuck on c syntax regarding strings. Say I have a string like (name[5]="peter";) in c say if I just wanted to print the last character of string or check the last character of the string, which in this case would be 'r' how can I do this? The way I was thinking does not seem to work name[5]="peter"; if(name[5]=="r") printf("last character of name is r"); Question: is there some sort of function to do this that can check one character of array, is a certain value, like name[5] is 'r' in string peter or likewise name[1] is 'n' Also how do I use printf to print that certain char, having problems using printf("last character of name is %s",name[5]) ??? Thanks

  • const correctness

    - by ra170
    I was going through: C++ FAQs about inheritance and decided to implement it (just to learn it) #include "Shape.h" void Shape::print() const { float a = this->area(); // area() is pure virtual ... } now, everything (well, almost) works as described in item: faq:23.1 except that print() is const and so it can't access the "this" pointer, as soon as you take out const, it works. Now, C++ FAQs have been around for a while and are usually pretty good. Is this a mistake? Do they have typo or am I wrong? If I'm wrong, I would like to know how is it possible to access the "this" pointer in a const function.

  • Converting excel files to python to frequency

    - by Jacob
    Essentially I've got an excel files with voltage in the first column, and time in the second. I want to find the period of the voltages, as it returns a graph of voltage in y axis and time in x axis with a periodicity, looking similar to a sine function. To find the frequency I have uploaded my excel file to python as I think this will make it easier- there may be something I've missed that will simplify this. So far in python I have: import xlrd import numpy as N import numpy.fft as F import matplotlib.pyplot as P wb = xlrd.open_workbook('temp7.xls') #LOADING EXCEL FILE wb.sheet_names() sh = wb.sheet_by_index(0) first_column = sh.col_values(1) #VALUES FROM EXCEL second_column = sh.col_values(2) #VALUES FROM EXCEL Now how do I find the frequency from this? Huge thanks to anyone who can help! Jacob

  • What does subl do here?

    - by drozzy
    So... I'm compiling into assembler, with gcc -S -O2 -m32: void h(int y){int x; x=y+1; f(y); f(2); } And it gives me the following: .file "sample.c" .text .p2align 4,,15 .globl h .type h, @function h: pushl %ebp movl %esp, %ebp subl $24, %esp movl 8(%ebp), %eax movl %eax, (%esp) call f movl $2, 8(%ebp) leave jmp f .size h, .-h .ident "GCC: (GNU) 4.4.3 20100127 (Red Hat 4.4.3-4)" .section .note.GNU-stack,"",@progbits Now I know what pushl and movel: they store the current frame pointer onto the stack and then set the value of the frame pointer register to the value of the Stack Pointer. But I have no idea what the subl $24, %esp is. Thanks!

  • how to ingore comma when returning json mvc

    - by Darcy
    Hi all, I'm returning JSON from my controller to my view in order to populate a jquery autocomplete textbox in MVC. The problem is, some of my data contains commas, and therefore is split by the autocomplete helper. Heres my code. Controller: public ActionResult GetData() { var data = repository.GetData(); return Json(data); } View (script): $.post("../MyController/GetData", function(data) { var evalData = eval(data) + ""; //formats the text $("#Data").autocomplete(evalData.split(","), { max: 500, matchContains: true }); }); As you can see, I am using the jquery .split helper to split the returned Json. Should I be using regex or should I go with a completely different approach?

  • Why does the textField not show up when I change the defaultTextFormat

    - by Leon
    I have an if/else statement which checks the length of my current title, and then is suppose to change the defaultTextFormat of the title textField and set the text. Currently the title will not show up now, no matter what character length the title is, any thoughts on what I could be doing wrong here? public function switchTitle(sentText):void { titleString = sentText; trace("---------"+"\n"); trace("Forumula testing"); trace("titleString = "+titleString); trace("titleString.length = "+titleString.length); trace("titleSize/10 = "+(titleSize/10)); trace("\n"); // If Title can fit: if (titleString.length < (titleSize/10)) { vTitle.defaultTextFormat = Fonts.VideoTitle; titleString = sentText; // If Title can't fit: } else if (titleString.length >= (titleSize/10)) { vTitle.defaultTextFormat = Fonts.VideoTitle2; titleString = sentText; } trace("---------"+"\n"); //vTitle.text = titleString; // <-- Original code, worked }

  • jQuery UI: Drag and clone from original div, but keep clones

    - by Nic Hubbard
    I have a div, which has jQuery UI Draggable applied. What I want to do, is click and drag that, and create a clone that is kept in the dom and not removed when dropped. Think of a deck of cards, my box element is the deck, and I want to pull cards/divs off that deck and have them laying around my page, but they would be clones of the original div. I just want to make sure that you cannot create another clone of one of the cloned divs. I have used the following, which didn't work like I wanted: $(".box").draggable({ axis: 'y', containment: 'html', start: function(event, ui) { $(this).clone().appendTo('body'); } });

  • MySQL: Transactions across multiple threads

    - by Zombies
    Preliminary: I have an application which maintains a thread pool of about 100 threads. Each thread can last about 1-30 seconds before a new task replaces it. When a thread end, that thread almost always will result in inserting 1-3 records into a table, this table is used by all of the threads. Right now, no transactional support exists, but I am trying to add that now. So... Goal I want to implement a transaction for this. The rules for whether or not this transaction commits or rollback reside in the main thread. Basically there is a simple function that will return a boolean. Can I implement a transaction across multiple connections? If not, can multiple threads share the same connection? (Note: there are a LOT of inserts going on here, and that is a requirement).

  • Sharepoint checkin/checkout

    - by Prashanth
    We have a sharepoint based application that uses a custom database for storing metadata/files (which could also be on a file share) My question is how can the standard file checkin/check out option in document library be customized? The javascript file ows.js in the layouts folder contains the functions that provide checkin/check out/ open file functionality. Behind the scenes it relies on a combination of HTTP Post/GET methods + SOAP + an activeX control to achieve the desired functionality. Customizing these javascript function seems tedious/error prone. Note that we have a web service that exposes endpoints, for retrieving necessary file information/data from the backend. The difficulty is in integrating it with the sharepoint js functions, due to lack of proper documentation. (Also the js functions might change over different versions of sharepoint) Also is it possible to create files/open files etc from the cache area on the client machine from server side code?

  • MFMailComposerViewController doesn't always display attachments

    - by davbryn
    I'm attaching a few files to an email to export from the application I've written, namely a .pdf and a .png. I create these by rendering some view to a context and creating an image and a pdf. I can validate that the files are created properly (I can confirm this by looking in my apps sandbox from Finder, and also by sending the email. I receive the files correctly.) The problem I'm getting is that larger files don't have a preview generated for them within the MFMailComposerViewController view (I simply get a blue icon with a question mark). Is there a limitation on file sizes that can be attached in order for preview to function correctly? With small files it works as expected, but if I try and attach a pdf with the following properties: Pages: 1 Dimensions: 2414 x 1452 Size: 307 KB the file is generated correctly, but displays the question mark icon. If there is no way around that, can I remove the attachment preview altogether? Many thanks, Bryn

  • Use LINQ and lambdas to put string in proper case

    - by Tobias Funke
    I have this function called ProperCase that takes a string, then converts the first letter in each word to uppercase. So ProperCase("john smith") will return "John Smith". Here is the code: public string ProperCase(string input) { var retVal = string.Empty; var words = input.Split(' '); foreach (var word in words) { if (word.Length == 1) { retVal += word.ToUpper(); } else if (word.Length > 1) { retVal += word.Substring(0, 1).ToUpper() + word.Substring(1).ToLower(); } retVal += ' '; } if (retVal.Length > 0) { retVal = retVal.Substring(0, retVal.Length - 1); } return retVal; } This code workds perfectly, but I'm pretty sure I can do it more elegantly with LINQ and lambdas. Can some please show me how?

  • Python Pari Library?

    - by silinter
    Pari/GP is an excellent library for functions relating to number theory. The problem is that there doesn't seem to be an up to date wrapper for python anywhere around, (pari-python uses an old version of pari) and I'm wondering if anyone knows of some other library/wrapper that is similar to pari or one that uses pari. I'm aware of SAGE, but it's far too large for my needs. GMPY is excellent as well, but there are some intrinsic pari functions that I miss, and I'd much rather use python than the provided GP environment. NZMATH, mpmath, scipy and sympy were all taken into consideration as well. On a related note, does anyone have any suggestions on loading the pari dll itself and using the functions contained in it? I've tried to very little success, other than loading it and learning about function pointers.

  • How to escape simple SQL queries in C# for SqlServer

    - by sri
    I use an API that expects a SQL string. I take a user input, escape it and pass it along to the API. The user input is quiet simple. It asks for column values. Like so: string name = userInput.Value; Then I construct a SQL query: string sql = string.Format("SELECT * FROM SOME_TABLE WHERE Name = '{0}'", name.replace("'", "''")); Is this safe enough? If it isn't, is there a simple library function that make column values safe: string sql = string.Format("SELECT * FROM SOME_TABLE WHERE Name = '{0}'", SqlSafeColumnValue(name)); The API uses SQLServer as the database. Thanks.

  • How to write program to do file transfer based on based omniORBpy

    - by cofthew7
    I'm now writing a Corba project to do file transfering between client and server. But I face trouble when I want to upload file from the client to the server. The IDL I defined is: interface SecretMessage { string send_file(in string file_name, in string file_obj); }; And I implemented the uploading function in the client code: f = open('SB.docx', 'rb') data = '' for piece in read_in_chunks(f): data += piece result = mo.send_file('2.docx', data) If the file is a plain txt file, there is no problem. But if the file is a, like jpg, doc, or others except txt, then it does work. It gives me the error: omniORB.CORBA.BAD_PARAM: CORBA.BAD_PARAM(omniORB.BAD_PARAM_WrongPythonType, CORBA.COMPLETED_NO) Where is the problem?

  • Open working copy file from eclipse history view

    - by Wolfgang
    The history view of eclipse shows you a list of files changed in a certain revision. When you open the context menu on one of these you have the option 'Open' which opens a view of that file in that revision. How can I open the editor for the selected file, i.e. the file in the version of the working copy, right from the history view? Background is that I want to use the history view to find files that have been changed recently to do code reviewing. People commit via subversion and I use subclipse to connect eclipse to the subversion server. Today, I must use the 'Open resource'/'Open type' function and type the name of the file that I can read from the history view.

  • Understanding the "Instantiation" of Actionscript/Flash Objects

    - by parallax7d
    Could someone expand and clarify the different logical instantiations of objects in actionscript? So far it seems there are 3 layers of instantiations, for lack of a better term. The first one is declaring a variable/type. Next is instantiating that variable with something solid in the code, like a method or function? Is this just a way to glue things together? Then after that you instantiate it on the stage, is this something you have to do explicitly, or is it a side effect? Is this "3 layer" concept the correct way of looking at it, kind of like the MVC for flash app logic?
