  • Trying to send XML via EMail and the XML includes a byte[]

    - by barbary
    Hello All, I want to send an email that has a machine readable part you cut and paste into an asp.net page and you get the information. I have stored all the information in an object and then used an XMLSerizer to create some xml. It all worked fine until I added some Images as byte[] to the object. If I dump the resulting string to disk then I can recreate the object fine but after it appears in the email client and I try to cut and paste it it never works. Clearly there are non standard characters coming out that email clients don't like. Is there some encoding I could apply to my XML that would make it display correctly in an email client? Then I could cut, paste, decode and deserilize to get my object back. Please an example of how to encode the string in c# would be great.

  • Overload the behavior of count() when called on certain objects

    - by Tom
    In PHP 5, you can use magic methods, overload some classes, etc. In C++, you can implement functions that exist is STL as long as the argument types are different. Is there a way to do this in PHP? An example of what I'd like to do is this: class a { function a() { $this->list = array("1", "2"); } } $blah = new a(); count($blah); I would like blah to return 2. IE count the values of a specific array in the class. So in C++, the way I would do this might look like this: int count(a varName) { return count(varName->list); } Basically, I am trying to simplify data calls for a large application so I can call do this: count($object); rather than count($object->list); The list is going to be potentially a list of objects so depending on how it's used, it could be really nasty statement if someone has to do it the current way: count($object->list[0]->list[0]->list); So, can I make something similar to this: function count(a $object) { count($object->list); } I know PHP's count accepts a mixed var, so I don't know if I can override an individual type.

  • I want to create an expression for querystrings, this stuff is hard!

    - by jkirkerx
    I want to extract some keywords out of a query string for a search application in asp.net. I decoded the url string first, so it's plain text I have this to start with, but I want to add a keyword group I'd like to trim off the stuff for pure words, but not sure if that's possible I also have a long list of possible query string value fields that I want to check against ?q= @q= ?qs= &qs=

  • wifi provider onLocationChanged is never called

    - by Kelsie
    I got a weird problem. I uses wifi to retrieve user location. I have tested on several phones; on some of them, I could never get a location update. it seemed that the method onLocationChanged is never called. My code is attached below.. Any suggestions appreciated!!! @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager locationManager; locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); String provider = locationManager.NETWORK_PROVIDER; Location l = locationManager.getLastKnownLocation(provider); updateWithNewLocation(l); locationManager.requestLocationUpdates(provider, 0, 0, locationListener); } private void updateWithNewLocation(Location location) { TextView myLocationText; myLocationText = (TextView)findViewById(R.id.myLocationText); String latLongString = "No location found"; if (location != null) { double lat = location.getLatitude(); double lng = location.getLongitude(); latLongString = "Lat:" + lat + "\nLong:" + lng; } myLocationText.setText("Your Current Position is:\n" + latLongString); } private final LocationListener locationListener = new LocationListener() { public void onLocationChanged(Location location) { updateWithNewLocation(location); Log.i("onLocationChanged", "onLocationChanged"); Toast.makeText(getApplicationContext(), "location changed", Toast.LENGTH_SHORT).show(); } public void onProviderDisabled(String provider) {} public void onProviderEnabled(String provider) {} public void onStatusChanged(String provider, int status, Bundle extras) {} }; Manifest <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.INTERNET"/>

  • C# Possible to have a generic return type?

    - by JL
    Here is a typical function that returns either true/false; private static bool hasValue() { return true; } Now on an error, I would like to return my own custom error object with definition: public class Failure { public string failureDateTime { get; set; } public string failureReason { get; set; } } I would have expected to be able to throw this custom object for example... private static bool hasValue() { throw new Failure(); } This is not possible, and I don't want to derive Failure from System.IO.Exception because of the inability to serialize an exception in C#. What is the best practice / or ideal solution to this problem. Should I just work with private static object? Or is there a cleaner way to return a custom object or bypass the typical return type on an error (not using System.IO.Exception)? Not entirely wild about object either, because then I need to cast the result and validate it by more boolean logic.

  • Java reference storage question

    - by aab
    In java, when you pass an object to a method as a parameter, it is actually passing a reference, or a pointer, to that object because objects in Java are references. Inside the function, it has a pointer to that object which is a location in memory. I am wondering where this pointer lives in memory? Is a new memory location created once inside the function to hold this reference?

  • MediaType of REST

    - by user357243
    Hi, I am beginner in REST web services. I wrote a program of REST to display the HTML or XML. The @Path annotation's value is @Path("{typeDocument}"). There are two methods for GET : @GET @Produces(MediaType.TEXT_XML) public String getXml(@PathParam("typeDocument") String typeDocument) to display XML file, and @GET @Produces(MediaType.TEXT_HTML) public String getHtml(@PathParam("typeDocument") String typeDocument) to display HTML. The browser Firefox always excutes getHtml() when URL is either http://localhost:8080/sources/html or localhost:8080/sources/xml But IE always excutes getXml(). How to excute the correct method, as defined by URL, in different browser ? Thanks a lot.

  • How to match !x but not !!x in JS regex?

    - by mpeterson
    Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!

  • Need help with map (c++, STL)

    - by Mike Dooley
    Hi folks! Actually I'm new to C++. I tried something out (actually the map container) but it doesn't work the way I assumed it will... Before posting my code, I will explain it shortly. I created 3 classes: ClassA ClassDerivedA ClassAnotherDerivedA The two last ones are derived from "ClassA". Further I created a map: map<string,ClassA> test_map; I put some objects (from Type ClassDerivedA and ClassAnotherDerivedA) into the map. Keep in mind: the mapped value is from type "ClassA". This will only work because of Polymorphism. Finally I created an iterator which runs over my map and compares the user input with my keys in the map. If they match, it will call a specific method called "printOutput". And there is the Problem: Although i declared "printOutput" as "virtual" the only method called is the one from my base class, but why? and here is the code: #include <iostream> #include <map> using namespace std; class ClassA { public: virtual void printOutput() { cout << "ClassA" << endl; } }; class ClassDerivedA : public ClassA { public: void printOutput() { cout << "ClassDerivedA" << endl; } }; class ClassAnotherDerivedA: public ClassA { public: void printOutput() { cout << "ClassAnotherDerivedA" << endl; } }; int main() { ClassDerivedA class_derived_a; ClassAnotherDerivedA class_another_a; map<string,ClassA> test_map; test_map.insert(pair<string,ClassA>("deriveda", class_derived_a)); test_map.insert(pair<string,ClassA>("anothera", class_another_a)); string s; while( cin >> s ) { if( s != "quit" ) { map<string,ClassA>::iterator it = test_map.find(s); if(it != test_map.end()) it->second.printOutput(); } else break; } } Blockquote

  • How to discard const in c++

    - by Vincenzo
    This is what I'm trying to do and I can't: #include <string> using namespace std; class A { bool has() const { return get().length(); } string& get() { return s; } private: string s; }; The error I'm getting is: passing ‘const A’ as ‘this’ argument of ‘std::string& A::get()’ discards qualifiers I understand what the problem is, but how can I fix it? I really need has() to be const. Thanks.

  • Problems With SWT on Mac

    - by Jav
    I've got a java project that uses an SWT UI and I'm having trouble deploying it on any Mac OS X computers. The program itself works perfectly on Windows when it is either run from within Eclipse or from a jar file. On Mac, the program also works fine in Eclipse, but when I try to run it from a jar file, I get the following error: 2010-04-30 13:33:04.564 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x10b9b0 of class NSCFString autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678fb79 0x35a19b1 0x359ba7f) 2010-04-30 13:33:04.566 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x115ef0 of class NSCFNumber autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678a0b0 0x35a19b1 0x359ba7f) 2010-04-30 13:33:04.567 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x121000 of class NSCFString autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678fb79 0x35a19b1) 2010-04-30 13:33:04.581 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x123720 of class NSPathStore2 autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943ba637 0x943c238f 0x943c1e8e 0x943c694b 0x678992e 0x35a19b1) 2010-04-30 13:33:04.582 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x12d660 of class NSPathStore2 autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943ba637 0x943b9739 0x943c3eb2 0x943c6b22 0x678992e 0x35a19b1) ... ... ... The actual error is much larger, and continues until the program crashes. I know that I am using the correct swt.jar file and I have tried running the program with the -XstartOnFirstThread VM argument, but still have not had any luck. Does anybody have any ideas or any suggestions where I could start looking for a solution? Thanks.

  • Strange issue with cout

    - by ben
    After reading from a text file, and storing it into a string, I tried to pass this message into another function that will print it out. This is what it looks like: http://imgur.com/MCjfRdp void insert (int id, string message){ cout << "Inserting " << message << " at" << endl; } Somehow the message behind the string overrides the message. But once I removed the " at" after message, it worked as expected. http://imgur.com/JdHPPmi void insert (int id, string message){ cout << "Inserting " << message << endl; } I somehow suspect the problem came from stringstream, but i couldn't find out where. Here's the code that read from file vector <string> line; fstream infile; string readLine, tempLine, action, tempLine1; int level, no; infile.open(fileName.c_str(),ios::in); int i = 0; while (!infile.eof()) { getline (infile, readLine); line.push_back(readLine); } infile.close(); line.pop_back(); for (int i = 0; i < line.size();i++) { stringstream ss (line.at(i)); getline (ss, action, ' '); if (action == "init") { // some other work here } else if (action == "insert") { tempLine = line.at(i); ss >> no; stringstream iline(tempLine); getline (iline, tempLine1, ' '); getline (iline, tempLine1, ' '); getline (iline, tempLine1, '\n'); Insert (no, tempLine1); } Since my file has different kinds of actions, here is what test.dat contains: insert 0 THIS IS A TEST edit: When i did file.txt, it came out as something like this.

  • "this" in JavaScript

    - by cf_PhillipSenn
    I'm trying to understand the syntax of how to put together a JavaScript function as an object. Q: Is this the right way to do it? The reason why I ask is because I'm looking at it in Firebug and I was hoping to be able to drill down and see the value of myVar and myVariable, but instead Firebug only says that "this" is an object Object. var myObject = { init: function() { var myVar = 1; myObject.myVariable = 2; console.log('"this" when called as an object: ' + this); } } myObject.init(); Also, what's the funny little syntax to call it directly upon declaration? Something about (), but when I remove the last line and put () at the end of the declaration, I get a syntax error.

  • What encoding does c32rtomb convert to?

    - by R. Martinho Fernandes
    The functions c32rtomb and mbrtoc32 from <cuchar>/<uchar.h> are described in the C Unicode TR (draft) as performing conversions between UTF-321 and "multibyte characters". (...) If s is not a null pointer, the c32rtomb function determines the number of bytes needed to represent the multibyte character that corresponds to the wide character given by c32 (including any shift sequences), and stores the multibyte character representation in the array whose first element is pointed to by s. (...) What is this "multibyte character representation"? I'm actually interested in the behaviour of the following program: #include <cassert> #include <cuchar> #include <string> int main() { std::u32string u32 = U"this is a wide string"; std::string narrow = "this is a wide string"; std::string converted(1000, '\0'); char* ptr = &converted[0]; std::mbstate_t state {}; for(auto u : u32) { ptr += std::c32rtomb(ptr, u, &state); } converted.resize(ptr - &converted[0]); assert(converted == narrow); } Is the assertion in it guaranteed to hold1? 1 Working under the assumption that __STDC_UTF_32__ is defined.
