  • How to create Context Menu using XML file ?

    - by Kaillash
    I am using XML file for creating Context Menu for my ListView. (Please see below). I also want to set a header for this Context Menu. I read (at http://www.mail-archive.com/[email protected]/msg43062.html)that I can use menu.setHeaderTitle(myContextMenuTitle) in onCreateContextMenu Method. But I need to set this in XML file. How can I accomplish this? Following is code for onCreateContextMenu Method, correct me if I am doing anything wrong.. This is my context_menu.xml file: <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/open" android:title="Open"/> </menu> This is my onCreateContextMenu Method: @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.context_menu, menu); super.onCreateContextMenu(menu, v, menuInfo); } This is my onCreate Method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // extras = getIntent().getExtras(); registerForContextMenu(getListView()); ... }

  • Get remote image using cURL then resample.

    - by Chris
    I want to be able to retrieve a remote image from a webserver, resample it, and then serve it up to the browser AND save it to a file. Here is what I have so far: $ch = curl_init(); // set URL and other appropriate options curl_setopt($ch, CURLOPT_URL, "$rURL"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); // grab URL and pass it to the browser $out = curl_exec($ch); // close cURL resource, and free up system resources curl_close($ch); $imgRes = imagecreatefromstring($out); imagejpeg($imgRes, $filename, 70); header("Content-Type: image/jpg"); header("Content-length: ".filesize($filename)); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($filename)); readfile("$filename"); exit(); Update Updated code to include imjpeg step to save the image as lower quality. But how do I then, efficiently, serve this up to the browser. I currently, later in the code, do this readfile("$filename"); along with some header information but that means I'm reading the file back in again which seems inefficient.

  • HttpServerUtility.UrlTokenDecode fails "sometimes" (Invalid length for a Base-64 char array.)

    - by Josef
    We have an IHttpHandler for stylesheets and add a <link/> tag to the page like this: HtmlGenericControl link = new HtmlGenericControl("link"); link.Attributes.Add("rel", "stylesheet"); link.Attributes.Add("href", "stylesheet.axd?d=" + HttpServerUtility.UrlTokenEncode(token)); head.Controls.Add(link); In the stylesheet.axd handler, we UrlTokenDecode the d query string parameter like this: var token = HttpServerUtility.UrlTokenDecode(Request.QueryString["d"]); This works most of the time but every now and then we find one of the following two exceptions in our log: [FormatException: Invalid character in a Base-64 string.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) ... [FormatException: Invalid length for a Base-64 char array.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) System.Web.HttpServerUtilityWrapper.UrlTokenDecode(String input) ... Any ideas what would cause this phenomenon? Remarks: the resulting URL is < 1500, so below any known URL limits (e.g. IE: 2083) seems to be independent of user agent (we have these exceptions for IE6,7,8, FF & Chrome) our (unconfirmed) suspicions include AntiVirus products, HTTP proxies, browser addons found this remotely related question, but it's about a viewstate issue

  • Getting an Android App to Show Up in the market for "Sony Internet TV"(Google TV)

    - by user1291659
    I'm having a bit of trouble getting my app to show up in the market under GoogleTV. I've searched google's official documentation and I don't believe the manifest lists any elements which would invalidate the program; the only hardware requirement specified is landscape mode, wakelock and external storage(neither which should cause it to be filtered for GTV according to the documentation) and I set the uses touchscreen elements "required" attribute to false. below is the AndroidManifest.xml for my project: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.whateversoft" android:versionCode="2" android:versionName="0.1" > <uses-sdk android:minSdkVersion="8" /> <application android:icon="@drawable/ic_launcher" android:label="Color Shafted" android:theme="@style/Theme.NoBackground" android:debuggable="false"> <activity android:label="Color Shafted" android:name=".colorshafted.ColorShafted" android:configChanges = "keyboard|keyboardHidden|orientation" android:screenOrientation = "landscape"> <!-- Set as the default run activity --> <intent-filter > <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:label="Color Shafted Settings" android:name=".colorshafted.Settings" android:theme="@android:style/Theme" android:configChanges = "keyboard|keyboardHidden"> <!-- --> </activity> </application> <!-- DEFINE PERMISSIONS FOR CAPABILITIES --> <uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name = "android.permission.WAKE_LOCK"/> <uses-feature android:name="android.hardware.touchscreen" android:required="false" /> <!-- END OF PERMISSIONS FOR CAPABILITIES --> </manifest> I'm about to start promoting the app after the next major release so its been kind of a bummer since I can't seem to get this to work.

  • Dynamically created operators

    - by Gero
    I created a program using dev-cpp and wxwidgets which solves a puzzle. The user must fill the operations blocks and the results blocks, and the program will solve it. Im solving it using bruteforce, i generate all non repeated 9 length number combinations using a recursive algorithm. It does it pretty fast. Up to here all is great! But the problem is when my program operates depending the character on the blocks. Its extremely slow (it never gets the answer), because of the chars comparation against +, -, *, etc. Im doing a CASE. Is there some way or some programming language wich allows dinamic creation of operators? So i can define the operator ROW1COL2 to be a +, and the same way to all other operations. I leave a screenshot of the app, so its easier to understand how the puzzle works. http://www.imageshare.web.id/images/9gg5cev8vyokp8rhlot9.png PD: The algorithm works, i tryed it with a trivial puzzle, and solved it in a second.

  • Trouble parsing quotes with SAX parser (javax.xml.parsers.SAXParser)

    - by johnrock
    When using a SAX parser, parsing fails when there is a " in the node content. How can I resolve this? Do I need to convert all " characters? In other words, anytime I have a quote in a node: <node>characters in node containing "quotes"</node> That node gets butchered into multiple character arrays when the Handler is parsing it. Is this normal behaviour? Why should quotes cause such a problem? Here is the code I am using: import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.methods.HttpGet; import org.xml.sax.InputSource; import org.xml.sax.XMLReader; ... HttpGet httpget = new HttpGet(GATEWAY_URL + "/"+ question.getId()); httpget.setHeader("User-Agent", PayloadService.userAgent); httpget.setHeader("Content-Type", "application/xml"); HttpResponse response = PayloadService.getHttpclient().execute(httpget); HttpEntity entity = response.getEntity(); if(entity != null) { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); ConvoHandler convoHandler = new ConvoHandler(); xr.setContentHandler(convoHandler); xr.parse(new InputSource(entity.getContent())); entity.consumeContent(); messageList = convoHandler.getMessageList(); }

  • Accessing Unicode telugu text from Ms-Access Database in Java

    - by Ravi Chandra
    I have an MS-Access database ( A English-telugu Dictionary database) which contains a table storing English words and telugu meanings. I am writing a dictionary program in Java which queries the database for a keyword entered by the user and display the telugu meaning. My Program is working fine till I get the data from the database, but when I displayed it on some component like JTextArea/JEditorPane/ etc... the telugu text is being displayed as '????'. Why is it happening?. I have seen the solution for "1467412/reading-unicode-data-from-an-access-database-using-jdbc" which provides some workaround for Hebrew language. But it is not working for telugu. i.e I included setCharset("UTF8")before querying from the database. but still I am getting all '?'s. As soon as I got data from Resultset I am checking the individual characters, all the telugu characters are being encoded by 63 only. This is my observation. I guess this must be some type of encoding problem. I would be very glad if somebody provides some solution for this. Thanks in advance.

  • What key on a keyboard can be detected in the browser but won't show up in a text input?

    - by Brady
    I know this one is going to sound weird but hear me out. I have a heart rate monitor that is hooked up like a keyboard to the computer. Each time the heart rate monitor detects a pulse it sends a key stroke. This keystroke is then detected by a web based game running in the browser. Currently I'm sending the following keystroke: (`) In the browser base game I'm detecting the following key fine and if when the user is on any data input screens the (`) character is ignored using a bit of JavaScript. The problem comes when I leave the browser and go back to using the Operating system in other ways the (`) starts appearing everywhere. So my question is: Is there a key that can be sent via the keyboard that is detectable in the browser but wont have any notable output on the screen if I switch to other applications. I'm kind of looking for a null key. A key that is detectable in the browser but has no effect to the browser or any other system application if pressed.

  • [Google Maps] Trouble with invalid argument when switching jQueryUI based tabs

    - by Chad
    Here's a page with the issue To reproduce the error, using IE - click the directions tab, then any of the others. What I'm trying to do is this: On page load, do nothing really. However, when the directions tab loads - setup the map. Like so: $('#tabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "tabs-5") { // get map for directions var dirMap = new GMap2($("div#dirMap").get(0)); dirMap.setCenter(new GLatLng(35.79648921414565,139.40663874149323), 12); dirMap.enableScrollWheelZoom(); dirMap.addControl(new PanoMapTypeControl()); geocoder = new GClientGeocoder(); $("#dirMap").resizable({ stop: function() { dirMap.checkResize(); } }); // clear dirText $("div#dirMapText").html(""); dirMap.clearOverlays(); var polygon = new GPolygon([new GLatLng(35.724496338474104,139.3444061279297),new GLatLng(35.74748750802863,139.3363380432129),new GLatLng(35.75765724051559,139.34303283691406),new GLatLng(35.76545779822543,139.3418312072754),new GLatLng(35.767547103447725,139.3476676940918),new GLatLng(35.75835374997911,139.34955596923828),new GLatLng(35.755149755962755,139.3567657470703),new GLatLng(35.74679090345495,139.35796737670898),new GLatLng(35.74762682821177,139.36294555664062),new GLatLng(35.744422402303826,139.36346054077148),new GLatLng(35.74860206266584,139.36946868896484),new GLatLng(35.735644401200986,139.36843872070312),new GLatLng(35.73843117306677,139.36174392700195),new GLatLng(35.73592308277646,139.3531608581543),new GLatLng(35.72686543236113,139.35298919677734),new GLatLng(35.724496338474104,139.3444061279297)], "#f33f00", 5, 1, "#ff0000", 0.2);dirMap.addOverlay(polygon); // load directions directions = new GDirections(dirMap, $("div#dirMapText").get(0)); directions.load("from: [email protected],139.37083393335342 to: Ruby [email protected],139.40663874149323"); } }); What the heck is causing the error? The IE javascript debugger claims the error lies in main.js, line 139 character 28. (the google maps api file). Which is this line: function zf(a,b){a=a.style;a.width=b.getWidthString();a.height=b.getHeightString()} Any ideas? Thanks in advance!

  • How to access this data in PHP?

    - by George Edison
    Okay. Now I give up. I have been playing with this for hours. I have a variable name $data. The variable contains these contents: array ( 'headers' => array ( 'content-type' => 'multipart/alternative; boundary="_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_"', ), 'ctype_parameters' => array ( 'boundary' => '_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_', ), 'parts' => array ( 0 => stdClass::__set_state(array( 'headers' => array ( 'content-type' => 'text/plain; charset="iso-8859-1"', 'content-transfer-encoding' => 'quoted-printable', ), 'ctype_primary' => 'text', )), ), ) I removed some non-essential data. I want to access the headers value (on the second line above) - simple: $data->headers I want to access the headers value (on the fourteenth line after the stdClass:: stuff) - how? How can I possibly access the values within the stdClass::__set_state section? I tried var_export($data->parts); but all I get is NULL

If i have it display the workingString, it correctly displays the entire string, but for some reason, it isn't correctly making the array using the commas. i tried it without using the data file and it worked fine, so the problem comes from how I am importing the data. ideas?

"Content-Disposition: attachment;\n" . " filename=\"{$fileatt_name}\"\n" . "Content-Transfer-Encoding: base64\n\n" .$data. "\n\n" ); There are two problems when I do this. First, the contents of the email dissappear. Second, there is an error on the attachment. "Adobe Reader could not open June_flyer.pdf because it is either not a supported file type or because the file has been damaged (for example it was sent as an email attachment and wasn't correctly decoded)" Any ideas of how to deal with this? Thanks, JB

  • Component returned failure code: 0x80600011 [nsIXSLTProcessorObsolete.transformDocument]

    - by Sean Ochoa
    So, I'm using the XSLT plugin for JQuery, and here's my code: function AddPlotcardEventHandlers(){ // some code } function reportError(exception){ alert(exception.constructor.name + " Exception: " + ((exception.name) ? exception.name : "[unknown name]") + " - " + exception.message); } function GetPlotcards(){ $("#content").xslt("../xml/plotcards.xml","../xslt/plotcards.xsl", AddPlotcardEventHandlers,reportError); } Here's the modified jquery plugin. I say that its modified because I've added callbacks for success and error handling. /* * jquery.xslt.js * * Copyright (c) 2005-2008 Johann Burkard (<mailto:[email protected]>) * <http://eaio.com> * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

  • UTF-8 to Unicode conversion

    Hi, I am having problems with converting UTF-8 to Unicode. Below is the code: int charset_convert( char * string, char * to_string,char* charset_from, char* charset_to) { char *from_buf, *to_buf, *pointer; size_t inbytesleft, outbytesleft, ret; size_t TotalLen; iconv_t cd; if (!charset_from || !charset_to || !string) /* sanity check */ return -1; if (strlen(string) < 1) return 0; /* we are done, nothing to convert */ cd = iconv_open(charset_to, charset_from); /* Did I succeed in getting a conversion descriptor ? */ if (cd == (iconv_t)(-1)) { /* I guess not */ printf("Failed to convert string from %s to %s ", charset_from, charset_to); return -1; } from_buf = string; inbytesleft = strlen(string); /* allocate max sized buffer, assuming target encoding may be 4 byte unicode */ outbytesleft = inbytesleft *4 ; pointer = to_buf = (char *)malloc(outbytesleft); memset(to_buf,0,outbytesleft); memset(pointer,0,outbytesleft); ret = iconv(cd, &from_buf, &inbytesleft, &pointer, &outbytesleft);ing memcpy(to_string,to_buf,(pointer-to_buf); } main(): int main() { char UTF []= {'A', 'B'}; char Unicode[1024]= {0}; char* ptr; int x=0; iconv_t cd; charset_convert(UTF,Unicode,"UTF-8","UNICODE"); ptr = Unicode; while(*ptr != '\0') { printf("Unicode %x \n",*ptr); ptr++; } return 0; } It should give A and B but i am getting: ffffffff fffffffe 41 Thanks, Sandeep

  • Code Golf: Morse code

    - by LiraNuna
    The challenge The shortest code by character count, that will input a string using only alphabetical characters (upper and lower case), numbers, commas, periods and question mark, and returns a representation of the string in Morse code. The Morse code output should consist of a dash (-, ascii 0x2D) for a long beep (aka 'dah') and a dot (., ascii 0x2E) for short beep (aka 'dit'). Each letter should be separated by a space (' ', ascii 0x20), and each word should be separated by a forward slash (/, ascii 0x2F). Morse code table: Test cases: Input: Hello world Output: .... . .-.. .-.. --- / .-- --- .-. .-.. -.. Input: Hello, Stackoverflow. Output: .... . .-.. .-.. --- --..-- / ... - .- -.-. -.- --- ...- . .-. ..-. .-.. --- .-- .-.-.- Code count includes input/output (i.e full program).

  • A few questions about a Rails model for a simple addressbook app

    - by user284194
    I have a Rails application that lists information about local services. My objectives for this model are as follows: 1. Require the name and tag_list fields. 2. Require one or more of the tollfreephone, phone, phone2, mobile, fax, email or website fields. 3. If the paddress field has a value, then encode it with the Geokit plugin. Here is my entry.rb model: class Entry < ActiveRecord::Base validates_presence_of :name, :tag_list validates_presence_of :tollfreephone or :phone or :phone2 or :mobile or :fax or :email or :website acts_as_taggable_on :tags acts_as_mappable :auto_geocode=>{:field=>:paddress, :error_message=>'Could not geocode physical address'} before_save :geocode_paddress validate :required_info def required_info unless phone or phone2 or tollfreephone or mobile or fax or email or website errors.add_to_base "Please have at least one form of contact information." end end private def geocode_paddress #if paddress_changed? geo=Geokit::Geocoders::MultiGeocoder.geocode (paddress) errors.add(:paddress, "Could not Geocode address") if ! geo.success self.lat, self.lng = geo.lat,geo.lng if geo.success #end end end Requiring name and tag_list work, but requiring one (or more) of the tollfreephone, phone, phone2, mobile, fax, email or website fields does not. As for encoding with Geokit, in order to save a record with the model I have to enter an address. Which is not the behavior I want. I would like it to not require the paddress field, but if the paddress field does have a value, it should encode the geocode. As it stands, it always tries to geocode the incoming entry. The commented out "if paddress_changed?" was not working and I could not find something like "if paddress_exists?" that would work. Help with any of these issues would be greatly appreciated. I posted three questions pertaining to my model because I'm not sure if they are preventing each other from working. Thank you for reading my questions.

  • How to write to a varchar(max) column using ODBC

    - by andyjohnson
    Summary: I'm trying to write a text string to a column of type varchar(max) using ODBC and SQL Server 2005. It fails if the length of the string is greater than 8000. Help! I have some C++ code that uses ODBC (SQL Native Client) to write a text string to a table. If I change the column from, say, varchar(100) to varchar(max) and try to write a string with length greater than 8000, the write fails with the following error [Microsoft][ODBC SQL Server Driver]String data, right truncation So, can anyone advise me on if this can be done, and how? Some example (not production) code that shows what I'm trying to do: SQLHENV hEnv = NULL; SQLRETURN iError = SQLAllocEnv(&hEnv); HDBC hDbc = NULL; SQLAllocConnect(hEnv, &hDbc); const char* pszConnStr = "Driver={SQL Server};Server=127.0.0.1;Database=MyTestDB"; UCHAR szConnectOut[SQL_MAX_MESSAGE_LENGTH]; SWORD iConnectOutLen = 0; iError = SQLDriverConnect(hDbc, NULL, (unsigned char*)pszConnStr, SQL_NTS, szConnectOut, (SQL_MAX_MESSAGE_LENGTH-1), &iConnectOutLen, SQL_DRIVER_COMPLETE); HSTMT hStmt = NULL; iError = SQLAllocStmt(hDbc, &hStmt); const char* pszSQL = "INSERT INTO MyTestTable (LongStr) VALUES (?)"; iError = SQLPrepare(hStmt, (SQLCHAR*)pszSQL, SQL_NTS); char* pszBigString = AllocBigString(8001); iError = SQLSetParam(hStmt, 1, SQL_C_CHAR, SQL_VARCHAR, 0, 0, (SQLPOINTER)pszBigString, NULL); iError = SQLExecute(hStmt); // Returns SQL_ERROR if pszBigString len > 8000 The table MyTestTable contains a single colum defined as varchar(max). The function AllocBigString (not shown) creates a string of arbitrary length. I understand that previous versions of SQL Server had an 8000 character limit to varchars, but not why is this happening in SQL 2005? Thanks, Andy

  • [Cocoa] Can't find leak in my code.

    - by ryyst
    Hi, I've been spending the last few hours trying to find the memory leak in my code. Here it is: NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; expression = [expression stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]]; // expression is an NSString object. NSArray *arguments = [NSArray arrayWithObjects:expression, [@"~/Desktop/file.txt" stringByExpandingTildeInPath], @"-n", @"--line-number", nil]; NSPipe *outPipe = [[NSPipe alloc] init]; NSTask *task = [[NSTask alloc] init]; [task setLaunchPath:@"/usr/bin/grep"]; [task setArguments:arguments]; [task setStandardOutput:outPipe]; [outPipe release]; [task launch]; NSData *data = [[outPipe fileHandleForReading] readDataToEndOfFile]; [task waitUntilExit]; [task release]; NSString *string = [[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSUTF8StringEncoding]; string = [string stringByReplacingOccurrencesOfString:@"\r" withString:@""]; int linesNum = 0; NSMutableArray *possibleMatches = [[NSMutableArray alloc] init]; if ([string length] > 0) { NSArray *lines = [string componentsSeparatedByString:@"\n"]; linesNum = [lines count]; for (int i = 0; i < [lines count]; i++) { NSString *currentLine = [lines objectAtIndex:i]; NSArray *values = [currentLine componentsSeparatedByString:@"\t"]; if ([values count] == 20) [possibleMatches addObject:currentLine]; } } [string release]; [pool release]; return [possibleMatches autorelease]; I tried to follow the few basic rules of Cocoa memory management, but somehow there still seems to be a leak, I believe it's an array that's leaking. It's noticeable if possibleMatches is large. You can try the code by using any large file as "~/Desktop/file.txt" and as expression something that yields many results when grep-ing. What's the mistake I'm making? Thanks for any help! -- Ry
