• Google OAuthGetRequestToken returns "signature_invalid"

  - by M Schenkel

  Trying for hours to get a request token using Google OAuthGetRequestToken but it always returns "signature_invalid". For a test I use the oAuth Playground to successfully request the token. Here are the results: Signature base string GET&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetRequestToken&oauth_callback%3Dhttp%253A%252F%252Fgooglecodesamples.com%252Foauth_playground%252Findex.php%26oauth_consumer_key%3Dwww.embeddedanalytics.com%26oauth_nonce%3D56aa884162ed21815a0406725c79cf79%26oauth_signature_method%3DRSA-SHA1%26oauth_timestamp%3D1321417095%26oauth_version%3D1.0%26scope%3Dhttps%253A%252F%252Fwww.google.com%252Fanalytics%252Ffeeds%252F Request/Response GET /accounts/OAuthGetRequestToken?scope=https%3A%2F%2Fwww.google.com%2Fanalytics%2Ffeeds%2F HTTP/1.1 Host: www.google.com Accept: */* Authorization: OAuth oauth_version="1.0", oauth_nonce="56aa884162ed21815a0406725c79cf79", oauth_timestamp="1321417095", oauth_consumer_key="www.embeddedanalytics.com", oauth_callback="http%3A%2F%2Fgooglecodesamples.com%2Foauth_playground%2Findex.php", oauth_signature_method="RSA-SHA1", oauth_signature="qRtorIaSFaQdOXW1u6eMQlY9LT2j7ThG5kgkcD6rDcW4MIvzluslFgYRNTuRvnaruraNpItjojtgsrK9deYRKoHBGOlU27SsWy6jECxKczcSECl3cVAcjk7dvbywFMDkgi1ZhTZ5Q%2BFoD60HoVQUYnGUbOO0jPXI48LfkiA5ZN4%3D" HTTP/1.1 200 OK Content-Type: text/plain; charset=UTF-8 Date: Wed, 16 Nov 2011 04:18:15 GMT Expires: Wed, 16 Nov 2011 04:18:15 GMT Cache-Control: private, max-age=0 X-Content-Type-Options: nosniff X-XSS-Protection: 1; mode=block Content-Length: 118 Server: GSE oauth_token=4%2FmO86qZzixayI2NoUc-hewC--D53R&oauth_token_secret=r0PReF9D83w1d6uP0nyQQm9c&oauth_callback_confirmed=true I am using Fiddler to trace my calls.

• Creating share programmatically fails with error 9

  - by Christopher

  Directory.CreateDirectory("C:\MyTestShare") Dim managementClass As New ManagementClass("Win32_Share") Dim inParams As ManagementBaseObject = managementClass.GetMethodParameters("Create") inParams.Item("Description") = "My Files Share" inParams.Item("Name") = "My Files Share" inParams.Item("Path") = "C:\MyTestShare" inParams.Item("Type") = 0 If (DirectCast(managementClass.InvokeMethod("Create", inParams, Nothing).Properties.Item("ReturnValue").Value, UInt32) <> 0) Then Throw New Exception("Unable to share directory.") End If I am using the following code to set up a share, but I am always getting a return value of 9 which means invalid name. I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

• basic boost date_time input format question

  - by Chris H

  I've got a pointer to a string, (char *) as input. The date/time looks like this: Sat, 10 Apr 2010 19:30:00 I'm only interested in the date, not the time. I created an "input_facet" with the format I want: boost::date_time::date_input_facet inFmt("%a %d %b %Y"); but I'm not sure what to do with it. Ultimately I'd like to create a date object from the string. I'm pretty sure I'm on the right track with that input facet and format, but I have no idea how to use it. Thanks.

• Kind of stumped with some basic C# constructors.

  - by Sergio Tapia

  public class Parser { Downloader download = new Downloader(); HtmlDocument Page; public Parser(string MovieTitle) { Page = download.FindMovie(MovieTitle); } public Parser(string ActorName) { Page = download.FindActor(ActorName); } } I want to create a constructor that will allow other developers who use this library to easily create a Parser object with the relevant HtmlDocument already loaded as soon as it's done creating it. The problem lies in that a constructor cannot exist twice with the same type of parameters. Sure I can tell the logical difference between the two paramters, but the computer can't. Any suggestions on how to handle this? Thank you!

• C# streamreader, delimiter problem.

  - by Mike

  What I have is a txt file that is huge, 60MB. I need to read each line and produce a file, split based on a delimiter. I'm having no issue reading the file or producing the file, my complication comes from the delimiter, it can't see the delimiter. If anybody could offer a suggestion on how to read that delimiter I would be so grateful. delimiter = Ç public void file1() { string betaFilePath = @"C:\dtable.txt"; StringBuilder sb = new StringBuilder(); using (FileStream fs = new FileStream(betaFilePath, FileMode.Open)) using (StreamReader rdr = new StreamReader(fs)) { while (!rdr.EndOfStream) { string[] betaFileLine = rdr.ReadLine().Split('Ç'); { sb.AppendLine(betaFileLine[0] + "ç" + betaFileLine[1] + betaFileLine[2] + "ç" + betaFileLine[3] + "ç" + betaFileLine[4] + "ç" + betaFileLine[5] + "ç" + betaFileLine[6] + "ç" + betaFileLine[7] + "ç" + betaFileLine[8] + "ç" + betaFileLine[9] + "ç" + betaFileLine[10] + "ç"); } } } using (FileStream fs = new FileStream(@"C:\testarea\load1.txt", FileMode.Create)) using (StreamWriter writer = new StreamWriter(fs)) { writer.Write(sb.ToString()); } }

• JAXB, marshalling sub-class that has the same rootNode name as the superclass

  - by SCdF

  Let's say I have this: public class Foo { private String value; // <snip> getters and setters, constructors etc } And I also have this: public class Bar extends Foo { private String anotherValue; // <snip> getters and setters, constructors etc } I want to be able to marshall this to a Bar object: <foo> <value>smang</value> <anotherValue>wratz</anotherValue> </foo> I'm not in a position to check right now, but if I change the @XmlRootNode name of Bar to 'foo' will that work? Do I have to do anything more clever than that?

• [C#, Regex] EOL Special Char not matching

  - by Aurélien Ribon

  Hello, I am trying to find every "a - b, c, d" pattern in an input string. The pattern I am using is the following : "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$" The input is : a -> b b -> c c -> d The function is : private void ParseAndBuildGraph(String input) { MatchCollection mc = Regex.Matches(input, "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)(,[ \t]*\\w+)*$", RegexOptions.Multiline); foreach (Match m in mc) { Debug.WriteLine(m.Value); } } The output is : c -> d Actually, there is a problem with the line ending "$" special char. If I insert a "\r" before "$", it works, but I thought "$" would match any line termination (with the Multiline option), especially a \r\n in a Windows environment. Is it not the case ?

• Need help using the Windows IP Helper API & ParseNetworString in C#.

  - by JohnnyNoir

  I'm attempting to rewrite some C# web service code that uses the Windows IP Helper API call "SendARP" to retreive a remote system's MAC address. SendARP works great - until you cross a network segment as Arp requests aren't routed. I've been looking at the "ParseNetworkString" documentation after happening across its existance on StackOverflow. The quick & dirty algorithm I have in mind is: public static string GetMacAddress(string strHostOrIP) { if (strHostOrIP is IPAddress) { parse results of nbstat -A strHostOrIP return macAddress } if (strHostOrIP is Hostname) { IPHostEntry hostEntry = null; try { hostEntry = Dns.GetHostEntry(strHostOrIP); } catch { return null; } if (hostEntry.AddressList.Length == 0) { return null; } foreach (IPAddress ip in hostEntry.AddressList) { if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork) { ipAddress = ip; break; } } } return GetMACAddress(ipAddress); } "ParseNetworkString" is new with Vista/Win2008 so I haven't been able to find example C# code demonstrating its use and I'm no C++ coder so if anyone can point me in the right direction...

• Using hash functions with Bloom filters

  - by dangerstat

  Hi, A bloom filter uses a hash function (or many) to generate a value between 0 and m given an input string X. My question is how to you use a hash function to generate a value in this way, for example an MD5 hash is typically represented by a 32 length hex string, how would I use an MD5 hashing algorithm to generate a value between 0 and m where I can specify m? I'm using Java at the moment so an example of to do this with the MessageDigest functionality it offers would be great, though just a generic description of how to do about it would be fine too. Thanks

• Return/consume dynamic anonymous type across assembly boundaries

  - by friism

  The code below works great. If the Get and Use methods are in different assemblies, the code fails with a RuntimeBinderException. This is because the .Net runtime system only guarantees commonality of anonymous types (<string, int> in this case) within assemblies. Is there any way to fool the runtime system to overcome this? I can expect the object in the debugger on the Use side, and the debugger can see the relevant properties. class Program { static void Main(string[] args) { UsePerson(); Console.ReadLine(); } public static void UsePerson() { var person = GetPerson(); Console.WriteLine(person.Name); } public static dynamic GetPerson() { return new { Name = "Foo", Age = 30 }; } }

• Syntax to change the value of a cached object property

  - by Craig

  In an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum? The cache is set using: Public Shared Sub CacheSet(ByVal key As String, ByVal value As Object) Dim userID As String = HttpContext.Current.User.Identity.Name HttpContext.Current.Cache(key & "_" & userID) = value End Sub

• JPA character encoding

  - by wheelie

  Hi there, I have a Java Web application using GlassFish 3, JSF2.0 (facelets) and JPA (EclipseLink) on MySQL (URL: jdbc:mysql://localhost:3306/administer). The problem I'm facing is that if I'm saving entities to the database with the update() method, String data loses integrity; '?' is shown instead of some characters. The server, pages and database is/are configured to use UTF-8. After I post form data, the next page shows the data correctly. Furthermore it "seems" in debug that the String property of the current entity stores the correct value too. Dunno if NetBeans debug can be trusted; might be that it decodes correctly, however it's incorrect. Any help would be appreciated, thanks in advance! Daniel

• HQL query for entity with max value

  - by Rob

  I have a Hibernate entity that looks like this (accessors ommitted for brevity): @Entity @Table(name="FeatureList_Version") @SecondaryTable(name="FeatureList", pkJoinColumns=@PrimaryKeyJoinColumn(name="FeatureList_Key")) public class FeatureList implements Serializable { @Id @Column(name="FeatureList_Version_Key") private String key; @Column(name="Name",table="FeatureList") private String name; @Column(name="VERSION") private Integer version; } I want to craft an HQL query that retrieves the most up to date version of a FeatureList. The following query sort of works: Select f.name, max(f.version) from FeatureList f group by f.name The trouble is that won't populate the key field, which I need to contain the key of the record with the highest version number for the given FeatureList. If I add f.key in the select it won't work because it's not in the group by or an aggregate and if I put it in the group by the whole thing stops working and it just gives me every version as a separate entity. So, can anybody help?

• Using a boost::fusion::map in boost::spirit::karma

  - by user1097105

  I am using boost spirit to parse some text files into a data structure and now I am beginning to generate text from this data structure (using spirit karma). One attempt at a data structure is a boost::fusion::map (as suggested in an answer to this question). But although I can use boost::spirit::qi::parse() and get data in it easily, when I tried to generate text from it using karma, I failed. Below is my attempt (look especially at the "map_data" type). After some reading and playing around with other fusion types, I found boost::fusion::vector and BOOST_FUSION_DEFINE_ASSOC_STRUCT. I succeeded to generate output with both of them, but they don't seem ideal: in vector you cannot access a member using a name (it is like a tuple) -- and in the other solution, I don't think I need both ways (member name and key type) to access the members. #include <iostream> #include <string> #include <boost/spirit/include/karma.hpp> #include <boost/fusion/include/map.hpp> #include <boost/fusion/include/make_map.hpp> #include <boost/fusion/include/vector.hpp> #include <boost/fusion/include/as_vector.hpp> #include <boost/fusion/include/transform.hpp> struct sb_key; struct id_key; using boost::fusion::pair; typedef boost::fusion::map < pair<sb_key, int> , pair<id_key, unsigned long> > map_data; typedef boost::fusion::vector < int, unsigned long > vector_data; #include <boost/fusion/include/define_assoc_struct.hpp> BOOST_FUSION_DEFINE_ASSOC_STRUCT( (), assocstruct_data, (int, a, sb_key) (unsigned long, b, id_key)) namespace karma = boost::spirit::karma; template <typename X> std::string to_string ( const X& data ) { std::string generated; std::back_insert_iterator<std::string> sink(generated); karma::generate_delimited ( sink, karma::int_ << karma::ulong_, karma::space, data ); return generated; } int main() { map_data d1(boost::fusion::make_map<sb_key, id_key>(234, 35314988526ul)); vector_data d2(boost::fusion::make_vector(234, 35314988526ul)); assocstruct_data d3(234,35314988526ul); std::cout << "map_data as_vector: " << boost::fusion::as_vector(d1) << std::endl; //std::cout << "map_data to_string: " << to_string(d1) << std::endl; //*FAIL No 1* std::cout << "at_key (sb_key): " << boost::fusion::at_key<sb_key>(d1) << boost::fusion::at_c<0>(d1) << std::endl << std::endl; std::cout << "vector_data: " << d2 << std::endl; std::cout << "vector_data to_string: " << to_string(d2) << std::endl << std::endl; std::cout << "assoc_struct as_vector: " << boost::fusion::as_vector(d3) << std::endl; std::cout << "assoc_struct to_string: " << to_string(d3) << std::endl; std::cout << "at_key (sb_key): " << boost::fusion::at_key<sb_key>(d3) << d3.a << boost::fusion::at_c<0>(d3) << std::endl; return 0; } Including the commented line gives lots of pages of compilation errors, among which notably something like: no known conversion for argument 1 from ‘boost::fusion::pair’ to ‘double’ no known conversion for argument 1 from ‘boost::fusion::pair’ to ‘float’ Might it be that to_string needs the values of the map_data, and not the pairs? Though I am not good with templates, I tried to get a vector from a map using transform in the following way template <typename P> struct take_second { typename P::second_type operator() (P p) { return p.second; } }; // ... inside main() pair <char, int> ff(32); std::cout << "take_second (expect 32): " << take_second<pair<char,int>>()(ff) << std::endl; std::cout << "transform map_data and to_string: " << to_string(boost::fusion::transform(d1, take_second<>())); //*FAIL No 2* But I don't know what types am I supposed to give when instantiating take_second and anyway I think there must be an easier way to get (iterate over) the values of a map (is there?) If you answer this question, please also give your opinion on whether using an ASSOC_STRUCT or a map is better.

• c# HTTPListener encoding issue

  - by Rob Griffin

  I have a Java application sending HTTP requests to a C# application. The C# app uses HTTPListener to listen for requests and respond. On the Java side I'm encoding the URL using UTF-8. When I send a \ character it gets encoded as %5C as expected but on the C# side it becomes a / character. The encoding for the request object is Windows-1252 which I think may be causing the problem. How do I set the default encoding to UTF-8? Currently I'm doing this to convert the encoding: foreach (string key in request.QueryString.Keys) { if (key != null) { byte[] sourceBytes =request.ContentEncoding.GetBytes(request.QueryString[key]); string value = Encoding.UTF8.GetString(sourceBytes)); } } This handles the non ASCII characters I'm also sending but doesn't fix the slash problem. Examining request.QueryString[key] in the debugger shows that the / is already there.

• mysql and .net: when using tableadapters I'm getting MySqlException "insert command denied for user"

  - by Deveti Putnik

  Hi! I am using mysql as db for my asp.net application. Here are the facts: I am using connection string from web.config which has both username and password. I can do SELECT with tableadapter. When I am trying to do INSERT with tableadapter, I am getting "mysqlexception insert command denied for user" error When I try to do INSERT programatically, i.e. using connection, command object, etc. everything is fine. In this case, I'm reading connection string from web.config, too. This can be only applied to GoDaddy hosting, but on local machine I don't have this kind of problems. Can anyone suggest what can I do to make it work on GoDaddy hosting? Regards, D

• Problem with return 2 libc method

  - by jth

  Hi, I'am trying to understand the return2libc method. I'am using an ubuntu linux 9.10, 32 bit with ASLR disabled. In theory, it sounds quite easy, overwrite the saved eip with the address of system() (or whatever function you want), then put the address to which system() should return and after that, the parameter for system, the "/bin/bash"-string. But what happens is that my exploit keeps segfaulting the vulnerable program. I assume something with the system()-address went wrong. This is what I did so far: Determined the address of system(): (gdb) print system $1 = {<text variable, no debug info>} 0x167020 <system> (gdb) x/x system 0x167020 <system>: 0x890cec83 I used the subsequent x/x system because those 3 bytes returned by print system looks like an index in some sort of jumptable (PLT?), so I assume 0x890cec83 is the right address which is used to overwrite the saved eip. After that I determined the address of the /bin/bash string in memory, using a small C program which basically consists of this line: printf("Address of string /bin/bash: %p\n", getenv("SHELL")); Then I looked a little bit around in the memory and fount /bin/bash: (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" After I gathered this information, I filled the buffer: (gdb) b 9 Breakpoint 1 at 0x8048407: file victim.c, line 9. (gdb) r `perl -e 'print "A"x9 . "\x83\xec\x0c\x89FAKE\xca\f6\ff\bf";'` Breakpoint 1, main (argc=1111638594, argv=0xc360cca) at victim.c:10 10 return 0; (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" Stack frame looks like this: (gdb) i f Stack level 0, frame at 0xbffff440: eip = 0x8048407 in main (victim.c:10); saved eip 0x890cec83 source language c. Arglist at 0xbffff438, args: argc=1111638594, argv=0xc360cca Locals at 0xbffff438, Previous frame's sp is 0xbffff440 Saved registers: ebp at 0xbffff438, eip at 0xbffff43c This seems all right to me, saved eip was overwritten with the (hopefully) correct system()-address, return address for system was set to "FAKE" (shouldn't matter) and the address of /bin/bash also seems to be correct. When I'am continuing the execution, victim segfaults on some strange address and certainly not in 0x890cec83: (gdb) cont Continuing. Program received signal SIGSEGV, Segmentation fault. 0x0804840d in main (argc=Cannot access memory at address 0x41414149 ) at victim.c:11 11 } Has anyone an explanation or a hint what happens here and why the execution isn't redirected to 0x890cec83? Thanks in advance, any hint, and be it only vague, would be appreciated. I have no idea why this doesn't work.

• Different positions in ViewPager

  - by Kalai Selvan.G

  In my Application am using ViewPager to swipe the images,which comes through webservice as URL. Everything goes smoothly,the problem is while swiping myself getting the position as collapsed one.. Swipe left-right: positions are 1,2,3,4,5,etc.. if i stops swiping at 5th pos and started to Swipe from right-left: positions are 2,1...why this happens? I need to catch the position of the imageURL to find out the ID of the specific image and so i need to download and set it as wallpaper.. Normally while we swipe from right-left,the positions should decrease like 4,3,2,1. Also in debugger mode i got some start position,end position,last position with different values.. Any Clue about ViewPager. Here is my code: public class ImagePagerActivity extends BaseActivity { private ViewPager pager; private DisplayImageOptions options; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.ac_image_pager); Bundle bundle = getIntent().getExtras(); String[] imageUrls = bundle.getStringArray(Extra.IMAGES); int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0); options = new DisplayImageOptions.Builder() .showImageForEmptyUrl(R.drawable.image_for_empty_url) .cacheOnDisc() .decodingType(DecodingType.MEMORY_SAVING) .build(); pager = (ViewPager) findViewById(R.id.pager); pager.setAdapter(new ImagePagerAdapter(imageUrls)); pager.setCurrentItem(pagerPosition); } private class ImagePagerAdapter extends PagerAdapter { private String[] images; private LayoutInflater inflater; ImagePagerAdapter(String[] images) { this.images = images; inflater = getLayoutInflater(); } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager) container).removeView((View) object); } @Override public void finishUpdate(View container) { } @Override public int getCount() { return images.length; } @Override public Object instantiateItem(View view, int position) { final FrameLayout imageLayout = (FrameLayout) inflater.inflate(R.layout.item_pager_image, null); final ImageView imageView = (ImageView) imageLayout.findViewById(R.id.image); final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading); imageLoader.displayImage(images[position], imageView, options, new ImageLoadingListener() { public void onLoadingStarted() { spinner.setVisibility(View.VISIBLE); } public void onLoadingFailed() { spinner.setVisibility(View.GONE); imageView.setImageResource(android.R.drawable.ic_delete); } public void onLoadingComplete() { spinner.setVisibility(View.GONE); } }); ((ViewPager) view).addView(imageLayout, 0); return imageLayout; } @Override public boolean isViewFromObject(View view, Object object) { return view.equals(object); } @Override public void restoreState(Parcelable state, ClassLoader loader) { } @Override public Parcelable saveState() { return null; } @Override public void startUpdate(View container) { } } }

• Finite State Machine Spellchecker

  - by Durell

  I would love to have a debugged copy of the finite state machine code below. I tried debugging but could not, all the machine has to do is to spell check the word "and",an equivalent program using case is welcomed. #include<cstdlib> #include<stdio.h> #include<string.h> #include<iostream> #include<string> using namespace std; char in_str; int n; void spell_check() { char data[256]; int i; FILE *in_file; in_file=fopen("C:\\Users\\mytorinna\\Desktop\\a.txt","r+"); while (!feof(in_file)) { for(i=0;i<256;i++) { fscanf(in_file,"%c",in_str); data[i]=in_str; } //n = strlen(in_str); //start(data); cout<<data; } } void start(char data) { // char next_char; //int i = 0; // for(i=0;i<256;i++) // if (n == 0) { if(data[i]="a") { state_A(); exit; } else { cout<<"I am comming"; } // cout<<"This is an empty string"; // exit();//do something here to terminate the program } } void state_A(int i) { if(in_str[i] == 'n') { i++; if(i<n) state_AN(i); else error(); } else error(); } void state_AN(int i) { if(in_str[i] == 'd') { if(i == n-1) cout<<" Your keyword spelling is correct"; else cout<<"Wrong keyword spelling"; } } int main() { spell_check(); system("pause"); return 0; }

• Converting rich text that contains backslashes to plain text or html

  - by Allison

  I am trying to convert a rich text string to plain text or html. I am currently using the RichTextBox.Text feature which works correctly for almost all cases except when the text contains backslashes then some of the text is stripped out as the converter believes that it is part of the rtf formatting. Does anyone have any ideas of how to get the backslashes to stay in that instance. Here is an example of a string I would have {\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Arial;}}\viewkind4\uc1\pard\fs17 Testing Export \with comments\par} The text I would need would be "Testing Export \with comments" and the text I am getting back from the rtf converter is "Testing Export comments". Any help would be greatly appreciated. Please respond if you have further questions.

• Is POSTing a Dictionary to an .NET MVC action possible?

  - by Brenton Alker

  I have a form which contains a series of fields like: <input type="text" name="User[123]" value="Alice" /> <input type="text" name="User[456]" value="Bob" /> ... Where the index of the User array (123 and 456) are ID's associated with the value. I'm trying to update these values in the controller. My thinking is that a Dictionary that maps ID to name would work, but creating the action like: public void Save(Dictionary<string, string> user) { // ... } results in the user parameter being null. So, is passing a Dictionary possible? or, is there another method to achieve this?
