Serializable object in intent returning as String

- by B_

In my application, I am trying to pass a serializable object through an intent to another activity. The intent is not entirely created by me, it is created and passed through a search suggestion. In the content provider for the search suggestion, the object is created and placed in the SUGGEST_COLUMN_INTENT_EXTRA_DATA column of the MatrixCursor. However, when in the receiving activity I call getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY), the returned object is of type String and I cannot cast it into the original object class. I tried making a parcelable wrapper for my object that calls out.writeSerializable(...) and use that instead but the same thing happened. The string that is returned is like a generic Object toString(), i.e. com.foo.yak.MyAwesomeClass@4350058, so I'm assuming that toString() is being called somewhere where I have no control. Hopefully I'm just missing something simple. Thanks for the help! Edit: Some of my code This is in the content provider that acts as the search authority: //These are the search suggestion columns private static final String[] COLUMNS = { "_id", // mandatory column SearchManager.SUGGEST_COLUMN_TEXT_1, SearchManager.SUGGEST_COLUMN_INTENT_EXTRA_DATA }; //This places the serializable or parcelable object (and other info) into the search suggestion private Cursor getSuggestions(String query, String[] projection) { List<Widget> widgets = WidgetLoader.getMatches(query); MatrixCursor cursor = new MatrixCursor(COLUMNS); for (Widget w : widgets) { cursor.addRow(new Object[] { w.id w.name w.data //This is the MyAwesomeClass object I'm trying to pass }); } return cursor; } This is in the activity that receives the search suggestion: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Object extra = getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY); //extra.getClass() returns String, when it should return MyAwesomeClass, so this next line throws a ClassCastException and causes a crash MyAwesomeClass mac = (MyAwesomeClass)extra; ... }

Unable to insert DateTime format into database

- by melvg

I'm unable to insert the DateTime into my database. Am i writing the statement wrongly? Apparently without the DateTime, I am able to insert into the database string dateAndTime = date + " " + time; CultureInfo provider = CultureInfo.InvariantCulture; DateTime theDateTime = DateTime.ParseExact(dateAndTime, "d MMMM yyyy hh:mm tt", provider); //Create a connection, replace the data source name with the name of the SQL Anywhere Demo Database that you installed SAConnection myConnection = new SAConnection("UserID=dba;Password=sql;DatabaseName=emaDB;ServerName=emaDB"); //open the connection ; myConnection.Open(); //Create a command object. SACommand insertAccount = myConnection.CreateCommand(); //Specify a query. insertAccount.CommandText = ("INSERT INTO [meetingMinutes] (title,location,perioddate,periodtime,attenders,agenda,accountID,facilitator,datetime) VALUES ('"+title+"','" + location + "', '" + date + "','" + time + "', '" + attender + "','" + agenda + "', '" + accountID + "','" + facilitator + "','" +theDateTime+ "')"); try { insertAccount.ExecuteNonQuery(); if (title == "" || agenda == "") { btnSubmit.Attributes.Add("onclick", "displayIfSuccessfulInsert();"); //ScriptManager.RegisterStartupScript(this, GetType(), "error", "alert('Please ensure to have a title or agenda!');", true); } else { btnSubmit.Attributes.Add("onclick", "displayIfSuccessfulInsert();"); Response.Redirect("HomePage.aspx"); //ScriptManager.RegisterStartupScript(this, this.GetType(), "Redit", "alert('Minutes Created!'); window.location='" + Request.ApplicationPath + "/HomePage.aspx';", true); } } catch (Exception exception) { Console.WriteLine(exception); } finally { myConnection.Close(); } It does not insert the SQL into my database.

Convert enumeration to string

- by emptyheaded

I am trying to build a function that converts an item from an enum to its corresponding string. The enums I use are fairly long, so I didn't want to use a switch-case. I found a method using boost::unordered_map very convenient, but I don't know how to make a default return (when there is no item matching the enum). const boost::unordered_map<enum_type, const std::string> enumToString = boost::assign::map_list_of (data_1, "data_1") (data_2, "data_2"); I tried to create an additional function: std::string convert(enum_type entry) { if (enumToString.find(entry)) // not sure what test to place here, return enumToString.at(entry); //because the find method returns an iter else return "invalid_value"; } I even tried something exceedingly wrong: std::string convert(enum_type entry) { try{ return enumToString.at(entry); } catch(...){ return "invalid_value"; } } Result: evil "Debug" runtime error. Can somebody give me a suggestion on how to either 1) find an easier method to convert enum to a string with the same name as the enum item 2) find a way to use already built boost methods to get a default value from a hash map (best option) 3) find what to place in the test to use a function that returns either the pair of the key-value, or a different string if the key is not found in the map. Thank you very much.

PasswordFiled char[] to String in Java connection MySql?

- by user1819551

This is a jFrame to connect to the database and this is in the button connect. My issue is in the passwordField NetBeans make me do a char[], but my .getConnection not let me insert the char[] ERROR: "no suitable method found for getConnection(String,String,char[])". So I will change to String right? So when I change and run the jFrame said access denied. when I start doing the System.out.println(l) " Give me the right answer" Like this: "Alex". But when I do the System.out.println(password) "Give me the Array spaces and not the value" Like this: jdbc:mysql://localhost/home inventory root [C@5be5ab68 <--- Array space . What I doing wrong? try { Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver String host = "jdbc:mysql://"+tServerHost.getText()+"/"+tSchema.getText(); String uName = tUsername.getText(); char[] l = pPassword.getPassword(); System.out.println(l); String password= l.toString(); System.out.println(host+uName+l); con = DriverManager.getConnection(host, uName, password); System.out.println(host+uName+password); } catch (SQLException | ClassNotFoundException ex) { JOptionPane.showMessageDialog(this, ex.getMessage()); } }

c# logic to get the first non-repeating(distinct) character from the string

- by NoviceToDotNet

In c# i want to create logic that if i a string like abcabda is passed to a method then it should return first non repeative character from string like in above it should return c. i am unable to convert a string to array of character then how to make comparison of each array character to the string and return the first non repeative character. CanI make it like this? class A { static void main() { A a=new A(); char ch=a.m1(abcabd); } } class B { char m1(string s) { string s1=s; char[] ch1=new char[s.length]; for(int x=0; x<s.length;x++) { ch1[x]=s[x]; } for(int x=0; x<s.length; x++) { for(int y=0; y<s.lenth; y++) { if(s[x]=ch1[y]) { /// here i am confused how to create logic for comparison please let me know // and how to return the character } } } } }

I am using Virtualmin and have it set up to have Postfix scan incoming emails with ClamAV (using clamdscan) and delete any emails which contain a virus. However when I email myself the EICAR test string, it comes through just fine. I know ClamAV will report this file as a virus. How can I troubleshoot this / what could be wrong?

Using JAXB to unmarshal/marshal a List<String> - Inheritance

- by gerry

I've build the following case. An interface for all JAXBLists: public interface JaxbList<T> { public abstract List<T> getList(); } And an base implementation: @XmlRootElement(name="list") public class JaxbBaseList<T> implements JaxbList<T>{ protected List<T> list; public JaxbBaseList(){} public JaxbBaseList(List<T> list){ this.list=list; } @XmlElement(name="item" ) public List<T> getList(){ return list; } } As well as an implementation for a list of URIs: @XmlRootElement(name="uris") public class JaxbUriList2 extends JaxbBaseList<String> { public JaxbUriList2() { super(); } public JaxbUriList2(List<String> list){ super(list); } @Override @XmlElement(name="uri") public List<String> getList() { return list; } } And I'm using the List in the following way: public JaxbList<String> init(@QueryParam("amount") int amount){ List<String> entityList = new Vector<String>(); ... enityList.add("http://uri"); ... return new JaxbUriList2(entityList); } I thought the output should be: <uris> <uri> http://uri </uri> ... </uris> But it is something like this: <uris> <item xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:string"> http://uri </item> ... <uri> http://uri </uri> ... </uris> I think it has something to do with the inheritance, but I don't get it... What's the problem? - How can I fix it? Thanks in advance!

How to dynamically expand a string in C

- by sa125

Hi - I have a function that recursively makes some calculations on a set of numbers. I want to also pretty-print the calculation in each recursion call by passing the string from the previous calculation and concatenating it with the current operation. A sample output might look like this: 3 (3) + 2 ((3) + 2) / 4 (((3) + 2) / 4) x 5 ((((3) + 2) / 4) x 5) + 14 ... and so on So basically, the second call gets 3 and appends + 2 to it, the third call gets passed (3) + 2 , etc. My recursive function prototype looks like this: void calc_rec(int input[], int length, char * previous_string); I wrote a 2 helper functions to help me with the operation, but they implode when I test them: /********************************************************************** * dynamically allocate and append new string to old string and return a pointer to it **********************************************************************/ char * strapp(char * old, char * new) { // find the size of the string to allocate int len = sizeof(char) * (strlen(old) + strlen(new)); // allocate a pointer to the new string char * out = (char*)malloc(len); // concat both strings and return sprintf(out, "%s%s", old, new); return out; } /********************************************************************** * returns a pretty math representation of the calculation op **********************************************************************/ char * mathop(char * old, char operand, int num) { char * output, *newout; char fstr[50]; // random guess.. couldn't think of a better way. sprintf(fstr, " %c %d", operand, num); output = strapp(old, fstr); newout = (char*)malloc( 2*sizeof(char)+sizeof(output) ); sprintf(newout, "(%s)", output); free(output); return newout; } void test_mathop() { int i, total = 10; char * first = "3"; printf("in test_mathop\n"); while (i < total) { first = mathop(first, "+", i); printf("%s\n", first); ++i; } } strapp() returns a pointer to newly appended strings (works), and mathop() is supposed to take the old calculation string ("(3)+2"), a char operand ('+', '-', etc) and an int, and return a pointer to the new string, for example "((3)+2)/3". Any idea where I'm messing things up? thanks.

Classifying captured data in unknown format?

- by monch1962

I've got a large set of captured data (potentially hundreds of thousands of records), and I need to be able to break it down so I can both classify it and also produce "typical" data myself. Let me explain further... If I have the following strings of data: 132T339G1P112S 164T897F5A498S 144T989B9B223T 155T928X9Z554T ... you might start to infer the following: possibly all strings are 14 characters long the 4th, 8th, 10th and 14th characters may always be alphas, while the rest are numeric the first character may always be a '1' the 4th character may always be the letter 'T' the 14th character may be limited to only being 'S' or 'T' and so on... As you get more and more samples of real data, some of these "rules" might disappear; if you see a 15 character long string, then you have evidence that the 1st "rule" is incorrect. However, given a sufficiently large sample of strings that are exactly 14 characters long, you can start to assume that "all strings are 14 characters long" and assign a numeric figure to your degree of confidence (with an appropriate set of assumptions around the fact that you're seeing a suitably random set of all possible captured data). As you can probably tell, a human can do a lot of this classification by eye, but I'm not aware of libraries or algorithms that would allow a computer to do it. Given a set of captured data (significantly more complex than the above...), are there libraries that I can apply in my code to do this sort of classification for me, that will identify "rules" with a given degree of confidence? As a next step, I need to be able to take those rules, and use them to create my own data that conforms to these rules. I assume this is a significantly easier step than the classification, but I've never had to perform a task like this before so I'm really not sure how complex it is. At a guess, Python or Java (or possibly Perl or R) are possibly the "common" languages most likely to have these sorts of libraries, and maybe some of the bioinformatic libraries do this sort of thing. I really don't care which language I have to use; I need to solve the problem in whatever way I can. Any sort of pointer to information would be very useful. As you can probably tell, I'm struggling to describe this problem clearly, and there may be a set of appropriate keywords I can plug into Google that will point me towards the solution. Thanks in advance

SharedObject (Flex 3.2) behaving unexpectedly when query string present in URL

- by rhtx

Summary: The behavior detailed below seems to indicate that if your app at www.someplace.com sets/retrieves data via a SharedObject, there is some sort of .sol collision if the user hits your app at someplace.com, and then later at someplace.com?name=value. Can anyone confirm or refute this? I'm working on a Flex web app that presents the user with a login page. When the user has logged in, he/she is presented with a 'room' which is associated with a 'group'. We store the last-visited room/group combination in a SharedObject - so when a given user logs in, they are taken into the most recent room in which they were active. That works fine, but we also have an auto-login system which involves the user clicking on a link to the app url with a query string attached. There are two types of these links. 1) the query string includes username, groupId, and roomId 2) the query string includes only the username Because we are working fast and have only a few developers, the auto-login system is built on the last-vist system. During the auto-login process, the url is inspected and if groupId and roomId values are found in the query string, the SharedObject is opened and the last-visit group/room id values are overwritten by the param values. That works fine, also, when the app is hit with a query string of the second type (no groupId and roomId params), the app goes to the SharedObject to get the stored room and group id values, as it normally would. And here's the problem: The values it comes back with are whatever the last room/group param values were, not whatever the last last-visit room/group values are. And if the given user has never hit the app with query string that included group and room id values, the app gets null values from the SharedObject. It took some digging around, but what it looks like is happening is that a second set of data is being stored/expected in the SharedObject if a query string is present in the URL. Looking at the .sol file in a text editor I see more untranslated code, and additional group and room values, once I've hit the app with URLs that contain query strings. I'm not finding anything on the web about this, but that may just be due to a lack of necessary search skills. Has anyone else run into anything similar? Or do you know how to address this? I've tried setting Security.exactSettings to false, already - was really hoping that was going to work.

Is there a standard way to encode a .NET string into javascript string for use in MS AJAX?

- by Rich Andrews

I'm trying to pass the output of a SQL Server exception to the client using the RegisterStartUpScript method of the MS ScriptManager. This works fine for some errors but when the exception contains single quotes the alert fails. I dont want to only escape single quotes though - Is there a standard function i can call to escape any special chars for use in Javascript? string scriptstring = "alert('" + ex.Message + "');"; ScriptManager.RegisterStartupScript(this, this.GetType(), "Alert", scriptstring , true); Thanks tpeczek, the code almost worked for me :) but with a slight amendment (the escaping of single quotes) it works a treat. I've included my amended version here... public class JSEncode { /// <summary> /// Encodes a string to be represented as a string literal. The format /// is essentially a JSON string. /// /// The string returned includes outer quotes /// Example Output: "Hello \"Rick\"!\r\nRock on" /// </summary> /// <param name="s"></param> /// <returns></returns> public static string EncodeJsString(string s) { StringBuilder sb = new StringBuilder(); sb.Append("\""); foreach (char c in s) { switch (c) { case '\'': sb.Append("\\\'"); break; case '\"': sb.Append("\\\""); break; case '\\': sb.Append("\\\\"); break; case '\b': sb.Append("\\b"); break; case '\f': sb.Append("\\f"); break; case '\n': sb.Append("\\n"); break; case '\r': sb.Append("\\r"); break; case '\t': sb.Append("\\t"); break; default: int i = (int)c; if (i < 32 || i > 127) { sb.AppendFormat("\\u{0:X04}", i); } else { sb.Append(c); } break; } } sb.Append("\""); return sb.ToString(); } } As mentioned below - original source: here

php validation code format

- by user2970887

Use WLST to Delete All JMS Messages From a Destination

- by james.bayer

I got a question today about whether WebLogic Server has any tools to delete all messages from a JMS Queue. It just so happens that the WLS Console has this capability already. It’s available on the screen after the “Show Messages” button is clicked on a destination’s Monitoring tab as seen in the screen shot below. The console is great for something ad-hoc, but what if I want to automate this? Well it just so happens that the console is just a weblogic application layered on top of the JMX Management interface. If you look at the MBean Reference, you’ll find a JMSDestinationRuntimeMBean that includes the operation deleteMessages that takes a JMS Message Selector as an argument. If you pass an empty string, that is essentially a wild card that matches all messages. Coding a stand-alone JMX client for this is kind of lame, so let’s do something more suitable to scripting. In addition to the console, WebLogic Scripting Tool (WLST) based on Jython is another way to browse and invoke MBeans, so an equivalent interactive shell session to delete messages from a destination would looks like this: D:\Oracle\fmw11gr1ps3\user_projects\domains\hotspot_domain\bin>setDomainEnv.cmd D:\Oracle\fmw11gr1ps3\user_projects\domains\hotspot_domain>java weblogic.WLST Initializing WebLogic Scripting Tool (WLST) ...

Functional Adaptation

- by Charles Courchaine

In real life and OO programming we’re often faced with using adapters, DVI to VGA, 1/4” to 1/8” audio connections, 110V to 220V, wrapping an incompatible interface with a new one, and so on. Where the adapter pattern is generally considered for interfaces and classes a similar technique can be applied to method signatures. To be fair, this adaptation is generally used to reduce the number of parameters but I’m sure there are other clever possibilities to be had. As Jan questioned in the last post, how can we use a common method to execute an action if the action has a differing number of parameters, going back to the greeting example it was suggested having an AddName method that takes a first and last name as parameters. This is exactly what we’ll address in this post. Let’s set the stage with some review and some code changes. First, our method that handles the setup/tear-down infrastructure for our WCF service: 1: private static TResult ExecuteGreetingFunc<TResult>(Func<IGreeting, TResult> theGreetingFunc) 2: { 3: IGreeting aGreetingService = null; 4: try 5: { 6: aGreetingService = GetGreetingChannel(); 7: return theGreetingFunc(aGreetingService); 8: } 9: finally 10: { 11: CloseWCFChannel((IChannel)aGreetingService); 12: } 13: } Our original AddName method: 1: private static string AddName(string theName) 2: { 3: return ExecuteGreetingFunc<string>(theGreetingService => theGreetingService.AddName(theName)); 4: } Our new AddName method: 1: private static int AddName(string firstName, string lastName) 2: { 3: return ExecuteGreetingFunc<int>(theGreetingService => theGreetingService.AddName(firstName, lastName)); 4: } Let’s change the AddName method, just a little bit more for this example and have it take the greeting service as a parameter. 1: private static int AddName(IGreeting greetingService, string firstName, string lastName) 2: { 3: return greetingService.AddName(firstName, lastName); 4: } The new signature of AddName using the Func delegate is now Func<IGreeting, string, string, int>, which can’t be used with ExecuteGreetingFunc as is because it expects Func<IGreeting, TResult>. Somehow we have to eliminate the two string parameters before we can use this with our existing method. This is where we need to adapt AddName to match what ExecuteGreetingFunc expects, and we’ll do so in the following progression. 1: Func<IGreeting, string, string, int> -> Func<IGreeting, string, int> 2: Func<IGreeting, string, int> -> Func<IGreeting, int> For the first step, we’ll create a method using the lambda syntax that will “eliminate” the last name parameter: 1: string lastNameToAdd = "Smith"; 2: //Func<IGreeting, string, string, int> -> Func<IGreeting, string, int> 3: Func<IGreeting, string, int> addName = (greetingService, firstName) => AddName(greetingService, firstName, lastNameToAdd); The new addName method gets us one step close to the signature we need. Let’s say we’re going to call this in a loop to add several names, we’ll take the final step from Func<IGreeting, string, int> -> Func<IGreeting, int> in line as a lambda passed to ExecuteGreetingFunc like so: 1: List<string> firstNames = new List<string>() { "Bob", "John" }; 2: int aID; 3: foreach (string firstName in firstNames) 4: { 5: //Func<IGreeting, string, int> -> Func<IGreeting, int> 6: aID = ExecuteGreetingFunc<int>(greetingService => addName(greetingService, firstName)); 7: Console.WriteLine(GetGreeting(aID)); 8: } If for some reason you needed to break out the lambda on line 6 you could replace it with 1: aID = ExecuteGreetingFunc<int>(ApplyAddName(addName, firstName)); and use this method: 1: private static Func<IGreeting, int> ApplyAddName(Func<IGreeting, string, int> addName, string lastName) 2: { 3: return greetingService => addName(greetingService, lastName); 4: } Splitting out a lambda into its own method is useful both in this style of coding as well as LINQ queries to improve the debugging experience. It is not strictly necessary to break apart the steps & functions as was shown above; the lambda in line 6 (of the foreach example) could include both the last name and first name instead of being composed of two functions. The process demonstrated above is one of partially applying functions, this could have also been done with Currying (also see Dustin Campbell’s excellent post on Currying for the canonical curried add example). Matthew Podwysocki also has some good posts explaining both Currying and partial application and a follow up post that further clarifies the difference between Currying and partial application. In either technique the ultimate goal is to reduce the number of parameters passed to a function. Currying makes it a single parameter passed at each step, where partial application allows one to use multiple parameters at a time as we’ve done here. This technique isn’t for everyone or every problem, but can be extremely handy when you need to adapt a call to something you don’t control.

Is the timeago date format appropiate for a website?

- by Eduardo Campañó

We're building a website for a startup and we encourage using the "timeago" format for displaying dates (i.e. less than a minute ago, about 5 minutes ago, about a month ago, etc.) but the client argues that it's not used in the US, that people are just not used to it. I can make a list of hundreds of sites using it, but of course, I'm a geek. So in adition to the main question, what are the pros and cons of the "timeago" date format?

Should functions of a C library always expect a string's length?

- by Benjamin Kloster

I'm currently working on a library written in C. Many functions of this library expect a string as char* or const char* in their arguments. I started out with those functions always expecting the string's length as a size_t so that null-termination wasn't required. However, when writing tests, this resulted in frequent use of strlen(), like so: const char* string = "Ugh, strlen is tedious"; libFunction(string, strlen(string)); Trusting the user to pass properly terminated strings would lead to less safe, but more concise and (in my opinion) readable code: libFunction("I hope there's a null-terminator there!"); So, what's the sensible practice here? Make the API more complicated to use, but force the user to think of their input, or document the requirement for a null-terminated string and trust the caller?

How do I rip a dvd including menus and extras to a menu driven divx file (or any lossy format that supports menus)?

- by John Baber

I am asking exactly this question for the same reason, but would like to archive dvds as small, low quality video, while preserving the menu choosing experience. I would like to rip my dvds to something that has the same menus but whose video is in a much more compressed format. I do not want to copy a dvd to an .iso image. How can this be done in the most automatic (hopefully CLI) way possible? Any format is fine so long as playback on linux is possible.

How do you edit the "Preferred Format" settings in Rhythmbox?

- by skyblue

In Rhythmbox's Preferences, you can change the "Preferred Format" for Music to MPEG Layer 3 Audio, Ogg Vorbis, FLAC, or MPEG 4 Audio. However, despite there being a Settings button, it does not become enabled for any of these choices. (I have installed all of the gstreamer plugins, but this has made no difference.) So how can you change the "Preferred Format", for example to change the bit rate or the quality setting?

Configuration Error ASP.NET password format specified is invalid

- by salvationishere

I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS.

Parsing a Directory of files - Check for a String

- by i.h4d35

This is my first post here so kindly pardon any mistakes that I have. I'm still learning to find my way around Stack Exchange. I am trying to write a Java program that tries to scan a Directory full of either .txt,.rtf or.doc files(and none other). The aim is to search all the files in the directory, and find out if a particular string exists in the file. If it does, it returns the string and the filename that it found the string in. The aim of this program is, it is a project for school wherein the program scans the personal folders of call center employees to check if they have stored any CC/DC nos and if yes, report the folder name - to reduce CC fraud. The search function was fairly straight forward and works when I individually specify the filename. However, the searching the directory and passing the files to the search function has me stumped. I've posted my code so far, if you guys could look thru it and give me some feedback/suggestions, I'd really appreciate it. Thanks in advance import java.io.*; import java.util.*; public class parse2{ void traverse(String directory) throws FileNotFoundException { File dir = new File(directory); if (dir.isDirectory()) { String[] children = dir.list(); for (int i=0; i<children.length; i++) { //System.out.println("\n" + children[i]); reader(children[i]); } } } void reader(String loc) throws FileNotFoundException { FileReader fr = new FileReader(loc); BufferedReader br = new BufferedReader(fr); Scanner sc = new Scanner(br); char[] chkArray; int chk=1; char ch; while(sc.hasNext()) { String chkStr = sc.next(); chkArray = chkStr.toCharArray(); if ((chkArray[0]=='4')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } else if((chkArray[0]=='5')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } else if((chkArray[0]=='6')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } } } public static void main(String args[]) throws FileNotFoundException { parse2 P = new parse2(); P.traverse("C:/Documents and Settings/h4d35/Desktop/javatest/chk"); } }

How to map an IDictionary<String, CustomCollectionType> in NHibernate

- by devonlazarus

Very close to what I'm trying to do but not quite the answer I think I'm looking for: How to map IDictionary<string, Entity> in Fluent NHibernate I'm trying to implement an IDictionary<String, IList<MyEntity>>and map this collection to the database using NHibernate. I do understand that you cannot map collections of collections directly in NHibernate, but I do need the functionality of accessing an ordered list of elements by key. I've implemented IUserCollectionType for my IList<MyEntity> so that I can use IDictionary<String, MyCustomCollectionType> but am struggling with how to get the map to work as I'd like. Details This is the database I'm trying to model: ------------------------ -------------------- | EntityAttributes | | Entities | ------------------------ ------------------ -------------------- | EntityAttributeId PK | | Attributes | | EntityId PK | <- | EntityId FK | ------------------ | DateCreated | | AttributeId FK | -> | AttributeId PK | -------------------- | AttributeValue | | AttributeName | ------------------------ ------------------ Here are my domain classes: public class Entity { public virtual Int32 Id { get; private set; } public virtual DateTime DateCreated { get; private set; } ... } public class EavEntity : Entity { public virtual IDictionary<String, EavEntityAttributeList> Attributes { get; protected set; } ... } public class EavAttribute : Entity { public virtual String Name { get; set; } ... } public class EavEntityAttribute : Entity { public virtual EavEntity EavEntity { get; private set; } public virtual EavAttribute EavAttribute { get; private set; } public virtual Object AttributeValue { get; set; } ... } public class EavEntityAttributeList : List<EavEntityAttribute> { } I've also implemented the NH-specific custom collection classes IUserCollectionType and PersistentList And here is my mapping so far: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" ...> <class xmlns="urn:nhibernate-mapping-2.2" name="EavEntity" table="Entities"> <id name="Id" type="System.Int32"> <column name="EntityId" /> <generator class="identity" /> </id> ... <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <one-to-many class="EavEntityAttributeList" /> </map> </class> </hibernate-mapping> I know the <map> tag is partially correct, but I'm not sure how to get NH to utilize my IUserCollectionType to persist the model to the database. What I'd like to see (and this isn't right, I know) is something like: <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <list> <index column="DisplayOrder"> <one-to-many class="EntityAttributes"> </list> </map> Does anyone have any suggestions on how to properly map that IDictionary<String, EavEntityAttributeList> collection? I am using Fluent NH so I'll take examples using that library, but I'm hand mappings are just as helpful here.

Trying to convert string to datetime

- by user1596472

I am trying to restrict a user from entering a new record if the date requested already exits. I was trying to do a count to see if the table that the record would be placed in already has that date 1 or not 0. I have a calendar extender attached to a text box which has the date. I keep getting either a: String was not recognized as a valid DateTime. or Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'. depending on the different things I have tried. Here is my code. TextBox startd = (TextBox)(DetailsView1.FindControl("TextBox5")); TextBox endd = (TextBox)(DetailsView1.FindControl("TextBox7")); DropDownList lvtype = (DropDownList)(DetailsView1.FindControl("DropDownList6")); DateTime scheduledDate = DateTime.ParseExact(startd.Text, "dd/MM/yyyy", null); DateTime endDate = DateTime.ParseExact(endd.Text, "dd/MM/yyyy", null); DateTime newstartDate = Convert.ToDateTime(startd.Text); DateTime newendDate = Convert.ToDateTime(endd.Text); //foreach (DataRow row in sd.Tables[0].Rows) DateTime dt = newstartDate; while (dt <= newendDate) { //for retreiving from table Decimal sd = SelectCountDate(dt, lvtype.SelectedValue, countDate); String ndt = Convert.ToDateTime(dt).ToShortDateString(); // //start = string.CompareOrdinal(scheduledDate, ndt); // // end = string.CompareOrdinal(endDate, ndt); //trying to make say when leavetpe is greater than count 1 then throw error. if (sd > 0) { Response.Write("<script>alert('Date Already Requested');</script>"); } dt.AddDays(1); } ^^^ This version throws the: "String was not recognized as valid date type" error But if i replace the string with either of these : /*-----------------------Original------------------------------------ string scheduledDate = Convert.ToDateTime(endd).ToShortDateString(); string endDate = Convert.ToDateTime(endd).ToShortDateString(); -------------------------------------------------------------------*/ /*----------10-30--------------------------------------- DateTime scheduledDate = DateTime.Parse(startd.Text); DateTime endDate = DateTime.Parse(endd.Text); ------------------------------------------------------*/ I get the "Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'." error. I am just trying to stop a user from entering a record date that already exits. <InsertItemTemplate> <asp:TextBox ID="TextBox5" runat="server" Height="19px" Text='<%# Bind("lstdate", "{0:MM/dd/yyyy}") %>' Width="67px"></asp:TextBox> <asp:CalendarExtender ID="TextBox5_CalendarExtender" runat="server" Enabled="True" TargetControlID="TextBox5"> </asp:CalendarExtender> <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox5" ErrorMessage="*Leave Date Required" ForeColor="Red"></asp:RequiredFieldValidator> <br /> <asp:CompareValidator ID="CompareValidator18" runat="server" ControlToCompare="TextBox7" ControlToValidate="TextBox5" ErrorMessage="Leave date cannot be after start date" ForeColor="Red" Operator="LessThanEqual" ToolTip="Must choose start date before end date"></asp:CompareValidator> </InsertItemTemplate>
