  • FileNotFoundException when reading .xml file to parse

    - by thechiman
    I'm writing a program in Java where I read in data from an XML file and parse it. The file is imported into a folder named "Resources" in the src directory of my project. I'm using Eclipse. When I run the program, I get the following error: java.io.FileNotFoundException: /Users/thechiman/Dropbox/introcs/PSU SOC Crawler/resources/majors_xml_db.xml (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at java.io.FileInputStream.<init>(FileInputStream.java:66) ... The relevant code is here: private void parseXML() { //Get a factory DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); try { //Use factory to get a new DocumentBuilder DocumentBuilder db = dbf.newDocumentBuilder(); //Parse the XML file, get DOM representation dom = db.parse("resources/majors_xml_db.xml"); } catch(ParserConfigurationException pce) { pce.printStackTrace(); } catch(SAXException se) { se.printStackTrace(); } catch(IOException ioe) { ioe.printStackTrace(); } } I do not understand why I'm getting the FileNotFoundException when the file is there. Thanks for the help.

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?

  • What Is The Proper Location For One-Offs In VCS Repos?

    - by Joe Clark
    I have recently started using Mercurial as our VCS. Over the years, I have used RCS, CVS, and - for the last 5 years - SVN. Back 13 years ago, when I primarily used CVS and RCS, large projects went into CVS and one-offs were edited in place on the specific server and stored in RCS. This worked well as the one-offs were usually specific to the server and the servers were backed up nightly. Jump forward a decade and a lot of the one-off scripts became less centralized - they might be needed on any server at some random time. This was also OK, because now I was a begrudging SVN user. Everything (except for docs) got dumped into one repo. Jump to 2010. Now I am using Mercurial and am putting large projects in their own repo again. But what to do with the one-offs? The options as I see them: A repo for each script. It seems a bit cluttered to create a repo for every one page script that might get ran once a year. RCS Not an option. There are many possible servers that might need a specific script. Continuing to use SVN just for one-offs. No. There no advantage I see over the next option. Create a repo in Mercurial named "one-offs". This seems the most workable. The last option seems the best to me - however; is there a best practice regarding this? You also might be wondering if these scripts are truly one-offs if they will be reused. Some of them may be reused 6 months or a year from now - some, never. However, nearly all of them involve several man-hours of work due to either complex logic or extensive error checking. Simply discarding them is not efficient.

  • JNI: Long-object created with wrong value

    - by Torbjörn Eklund
    Hi! I am writing a c-jni function in Android, and I am having problems with creating a Long-object. I have succeeded in calling the constructor, but when I read the value of the object with longValue, I get the wrong result. jmethodID longConstructor; jmethodID longGetLongValue; jclass cls; jobject obj; // Create a object of type Long. cls = (*env)->FindClass(env,"java/lang/Long"); longConstructor = (*env)->GetMethodID(env,cls,"<init>","(J)V"); obj = (*env)->NewObject(env, cls, longConstructor, 4242); // Get the value by calling the function longValue. longGetLongValue= (*env)->GetMethodID(env,cls,"longValue","()J"); long return_long_value = (*env)->CallLongMethod(env, obj, longGetLongValue); // Log the result. LOGD("%li", return_long_value); I would expect that the above code would print 4242 in the log, however the value that is printed in the log is 1691768. Does anybody have an idea on why 4242 is not written in the log?

  • C++ Swig Python (Embedded Python in C++) works in Release but not in Debug

    - by sambha
    Platform: Windows 7, 64 bit (x64), Visual Studio 2008 I chose Python & Swig binding as the scripting environment of the application. As a prototype, created a simple VS solution with main() which initializes Python (Py_Initalize, Py_setPyHome, etc) & executes test.py. In the same solution created another project which is a DLL of a simple class. Used SWIG to wrap this class. This DLL is the _MyClasses.pyd. test.py creates the objects of my class & calls its member functions. All this works like a charm in the Release mode. But does not work in Debug mode (even tried banging my head on the laptop ;-) ). Output of my work looks like this (in both release & debug): x64 -debug - _MyClasses.pyd - MyClasses.py - test.exe - test.py - python26.dll - python26_d.dll Note that the debug version is linked against python26_d.lib. Had to build python myself for this! test.py import MyClasses print "ello" m = MyClasses.Male("John Doe", 25) print m.getType() Male is the C++ class. The problem: Traceback (most recent call last): File "test.py", line 6, in <module> import MyClasses File "...\x64\Debug\MyClasses.py", line 25, in <module> _MyClasses = swig_import_helper() File "...\x64\Debug\MyClasses.py", line 17, in swig_imp ort_helper import _MyClasses ImportError: No module named _MyClasses [15454 refs] I am used to Makefiles & am new to Visual Studio. I dont know who the culprit is here: Swig, The debug build of Python, Visual Studio, my stupidity. Thank you in advance. It will be a great help.

  • Is This a Valid Way to Use Blocks in Objective-C?

    - by Carter
    I've been building a HTTP client that uses web services to synchronize information between the client and server. I've been using Blocks and NSURLConnection to achieve this on the client side, but I'm getting frequent EXC_BAD_ACCESS crashes in objc_msgSend(). From what I understand, this usually means that a stored block that has fallen off the stack has been called. I think I've coded things correctly to avoid this, but I'm still stuck. Here is conceptually what my code is doing. It starts by calling "synchronizeWithWebServer". That method invokes "listRootObjectsOnServerWithBlock:" which takes in a block to be called when the method returns. "listRootObjectsOnServersWithBlock:" initiates a NSURLConnection to the web server asynchronously. It to expects a block to be called when it returns. Inside that block I want to be able to execute the original Block (so aptly named 'block'). This is only a simplified version of my code. The real synchronization process is more complex but it's mostly more of the same as what you see below. Sometimes the code works perfectly, but about 80% of the time it crashes very early on in the routine. It seems to be more vulnerable to crashing when my data set gets larger. - (void)synchronizeWithWebServer { [self listRootObjectsOnServerWithBlock:^(NSArray *results, NSError *error) { //Iterate over result objects and perform some other similar routines. }]; } - (void)listRootObjectsOnServerWithBlock:(void (^)(NSArray *results, NSError *error))block { //Create NSURLRequest Here //Create connection asynchronously. block = [block copy]; [NSURLConnection sendAsynchronousRequest:urlRequest queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){ //Parse response from web server (stored in NSData *data) NSArray *results = ..... //Call 'block' block(results, error); [block release]; }]; }

  • Using HttpClient with SSL and certificates

    - by ChrisCM
    While I've been familiar with HTTPS and the concept of SSL, I have recently begun some development and found I am a little confused. The requirement was that I write a small Java application that runs on a machine attached to a scanner. When a document is scanned this is picked up and the file (usually PDF) sent over the internet to our application server that will then process it. I've written the application using Apache Commons libraries and HTTPClient. The second requirement was to connect over SSL, requiring a certificate. Following guidance on the HTTPclient page I am using AuthSSLProtocolSocketFactory from the contributions page. The constructor can take a keystore, keystore password, truststore and truststore password. As an initial test our DBA enabled SSL on one of our development webservers and provided me with a .p12 file which when I imported into IE allows me to connect successfully. I am a bit confused between keystores and truststores and what steps I need to take using the keytool. I tried importing the p12 into a keystore file but get the error: keytool error: java.lang.Exception: Input not an X.509 certificate I followed a suggestion of importing the p12 into Internet Explorer and exporting as a .cer which I can then successfully import into a keystore. When I supply this as a keystore argument of the AuthSSLProtocolSocketFactory I get a meaningless errror, but if I try it as a truststore it seems like it reads it fine but ultimately I get Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate I am unsure if I have missed some steps, I am misunderstanding SSL and mutual authentication altogether or this is mis-configuration on the server side. Can anyone provide suggestions or point me towards resources that might help me figure this out please?

  • ORM model and DAO in my particular case

    - by EugeneP
    I have the DB structure as follows: table STUDENT (say, id, surname, etc) table STUDENT_PROPERTIES (say, name_of_the_property:char, value_of_the_property:char, student_id:FK) table COURSE (id, name, statusofcourse_id) table STATUSOFCOURSE (id, name_of_status:char ('active','inactive','suspended' etc)) table STUDENT_COURSE (student_id,course_id,statusofcourse_id) Let's try to pick up domain objects in my database: Student and Course are main entities. Student has a list of courses he attends, also he has a list of properties, that is all for this student. Next, Course entitity. It may contain a list of students that attend it. But in fact, the whole structure looks like this: the starting point is Student, with it's PK we can look a list of his properties, then we look into the STUDENT_COURSE and extract both FK of the Course entity and also the Status of the combination, it would look like "Student named bla bla, with all his properties, attends math and the status of it is "ACTIVE". now, quotation 1) Each DAO instance is responsible for one primary domain object or entity. If a domain object has an independent lifecycle, it should have its own DAO. 2) The DAO is responsible for creations, reads (by primary key), updates, and deletions -- that is, CRUD -- on the domain object. Now, first question is What are entities in my case? Student, Course, Student_Course, Status = all except for StudentProperties? Do I have to create a separate DAO for every object?

  • How to build an android test app with a dependency on another app using ant?

    - by Mike
    I have a module called MyApp, and another module called MyAppTests which has a dependency on MyApp. Both modules produce APKs, one named MyApp.apk and the other MyAppTests.apk. I normally build these in IntelliJ or Eclipse, but I'd like to create an ant buildfile for them for the purpose of continuous integration. I used "android update" to create a buildfile for MyApp, and thanks to commonsware's answer to my previous question I've been able to build it successfully using ant. I'd now like to build MyAppTests.apk using ant. I constructed the buildfile as before using "android update", but when I run it I get an error indicating that it's not finding any of the classes in MyApp. Taking a que from my previous question, I tried putting MyApp.apk into my MyAppTests/libs, but unfortunately that didn't miraculously solve the problem. What's the best way to build a test app APK using ant when it depends on classes in another APK? $ ant debug Buildfile: build.xml [setup] Project Target: Google APIs [setup] Vendor: Google Inc.

  • hg archive to Remote Directory

    - by Brett Daniel
    Is there any way to archive a Mercurial repository to a remote directory over SSH? For example, it would be nice if one could do the following: hg archive ssh://[email protected]/path/to/archive However, that does not appear to work. It instead creates a directory called ssh: in the current directory. I made the following quick-and-dirty script that emulates the desired behavior by creating a temporary ZIP archive, copying it over SSH, and unzipping the destination directory. However, I would like to know if there is a better way. if [[ $# != 1 ]]; then echo "Usage: $0 [user@]hostname:remote_dir" exit fi arg=$1 arg=${arg%/} # remove trailing slash host=${arg%%:*} remote_dir=${arg##*:} # zip named to match lowest directory in $remote_dir zip=${remote_dir##*/}.zip # root of archive will match zip name hg archive -t zip $zip # make $remote_dir if it doesn't exist ssh $host mkdir --parents $remote_dir # copy zip over ssh into destination scp $zip $host:$remote_dir # unzip into containing directory (will prompt for overwrite) ssh $host unzip $remote_dir/$zip -d $remote_dir/.. # clean up zips ssh $host rm $remote_dir/$zip rm $zip Edit: clone-and-push would be ideal, but unfortunately the remote server does not have Mercurial installed.

  • How to make Processes Run Parallel in Erlang?

    - by Ankit S
    Hello, startTrains() -> TotalDist = 100, Trains = [trainA,trainB ], PID = spawn(fun() -> train(1,length(Trains)) end), [ PID ! {self(),TrainData,TotalDist} || TrainData <- Trains], receive {_From, Mesg} -> error_logger:info_msg("~n Mesg ~p ~n",[Mesg]) after 10500 -> refresh end. so, I created Two Processes named trainA, trainB. I want to increment these process by 5 till it gets 100. I made different processes to make each of the train (process) increments its position parallely. But I was surprised to get the output sequentially i.e process trainA ends then process trainB starts. But I want to increment themselves at simultaneously. I want to run processes like this trainA 10 trainB 0 trainA 15 trainB 5 .... trainA 100 trainB 100 but I m getting trainA 0 .... trainA 90 trainA 95 trainA 100 trainA ends trainB 0 trainB 5 trainB 10 ..... trainB 100 How to make the processes run parallel/simultaneously? Hope you get my Q's. Please help me.

  • Validation without ServiceLocator

    - by Dmitriy Nagirnyak
    Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use S*ervice Locator*, so my validation would look like: public User : ICanValidate { public User() {} // We need this constructor (so no context known) public virtual string Username { get; set; } public IEnumerable<ValidationError> Validate() { if (ServiceLocator.GetService<IUserRepository>().FindUserByUsername(Username) != null) yield return new ValidationError("Username", "User already exists.") } } I already use Inversion Of control and Dependency Injection and really don't like the ServiceLocator due to number of facts: Harder to maintain implicit dependencies. Harder to test the code. Potential threading issues. Explicit dependency only on the ServiceLocator. The code becomes harder to understand. Need to register the ServiceLocator interfaces during the testing. But on the other side, with plain POCO objects, I do not see any other way of performing the validation like above without ServiceLocator and only using IoC/DI. So the question would be: is there any way to use DI/IoC for the situation described above? Thanks, Dmitriy.

  • How to marshall non-string objects with JAXB and Spring

    - by lesula
    I was trying to follow this tutorial in order to create my own restful web-service using Spring framework. The client do a GET request to, let's say http://api.myapp/app/students and the server returns an xml version of the object classroom: @XmlRootElement(name = "class") public class Classroom { private String classId = null; private ArrayList<Student> students = null; public Classroom() { } public String getClassId() { return classId; } public void setClassId(String classId) { this.classId = classId; } @XmlElement(name="student") public ArrayList<Student> getStudents() { return students; } public void setStudents(ArrayList<Student> students) { this.students = students; } } The object Student is another bean containing only Strings. In my app-servlet.xml i copied this lines: <bean id="studentsView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <constructor-arg ref="jaxbMarshaller" /> </bean> <!-- JAXB2 marshaller. Automagically turns beans into xml --> <bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>com.spring.datasource.Classroom</value> <value>com.spring.datasource.Student</value> </list> </property> </bean> Now my question is: what if i wanted to insert some non-string objects as class variables? Let's say i want a tag containing the String version of an InetAddress, such as <inetAddress>192.168.1.1</inetAddress> How can i force JAXB to call the method inetAddress.toString() in such a way that it appears as a String in the xml? In the returned xml non-string objects are ignored!

  • C++ Beginner - Trouble using classes inside of classes

    - by Francisco P.
    Hello, I am working on a college project, where I have to implement a simple Scrabble game. I have a player class (containing a Score and the player's hand, in the form of a std::string, and a score class (containing a name and numeric (int) score). One of Player's member-functions is Score getScore(), which returns a Score object for that player. However, I get the following error on compile time: player.h(27) : error C2146: syntax error : missing ';' before identifier 'getScore' player.h(27) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int player.h(27) : error C4430: missing type specifier - int assumed.

  • JAVA - Create variable names using a loop?

    - by SeerUK
    Hi, first time poster, long time reader so be gentle with me :) See the following code which works to generate me timestamps for the beginning and end of every month in a financial year. int year = 2010; // Financial year runs from Sept-Aug so earlyMonths are those where year = FY-1 and lateMonths are those where year = FY int[] earlyMonths = {8, 9, 10, 11}; // Sept to Dec int earlyYear = year -1; for (int i : earlyMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(earlyYear,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(earlyYear,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(earlyYear,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } int[] lateMonths = {0, 1, 2, 3, 4, 5, 6, 7}; // Jan to Aug for (int i : lateMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(year,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(year,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(year,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } So far so good, but in order to use these results I need these timestamps to be output to variables named by month (to be used in a prepared statement later in the code. e.g. SeptStart = sometimestamp, SeptEnd = some timestamp etc etc. I don't know if it is possible to declare new variables based on the results of each loop. Any ideas?

  • get column names from a table where one of the column name is a key word.

    - by syedsaleemss
    Im using c# .net windows form application. I have created a database which has many tables. In one of the tables I have entered data. In this table I have 4 columns named key, name,age,value. Here the name "key" of the first column is a key word. Now I am trying to get these column names into a combo box. I am unable to get the name "key". It works for "key" when I use this code: private void comboseccolumn_SelectedIndexChanged(object sender, EventArgs e) { string dbname = combodatabase.SelectedItem.ToString(); string path = @"Data Source=" + textBox1.Text + ";Initial Catalog=" + dbname + ";Integrated Security=SSPI"; //string path=@"Data Source=SYED-PC\SQLEXPRESS;Initial Catalog=resources;Integrated Security=SSPI"; SqlConnection con = new SqlConnection(path); string tablename = comboBox2.SelectedItem.ToString(); //string query= "Select * from" +tablename+; //SqlDataAdapter adp = new SqlDataAdapter(" Select [Key] ,value from " + tablename, con); SqlDataAdapter adp = new SqlDataAdapter(" Select [" + combofirstcolumn.SelectedItem.ToString() + "]," + comboseccolumn.SelectedItem.ToString() + "\t from " + tablename, con); DataTable dt = new DataTable(); adp.Fill(dt); dataGridView1.DataSource = dt; } This is beacuse I am using "[" in the select query. But it wont work for non keys. Or if I remove the "[" it is not working for key . Please suggest me so that I can get both key as well as nonkey column names.

  • merge() multiple data frames (do.call ?)

    - by Vincent
    Hi everyone, here's my very simple question: merge() only takes two data frames as input. I need to merge a series of data frames from a list, using the same keys for every merge operation. Given a list named "test", I want to do something like: do.call("merge", test). I could write some kind of loop, but I'm wondering if there's a standard or built-in way to do this more efficiently. Any advice is appreciated. Thanks! Here's a subset of the dataset in dput format (note that merging on country is trivial in this case, but that there are more countries in the original data): test <- list(structure(list(country = c("United States", "United States", "United States", "United States", "United States"), NY.GNS.ICTR.GN.ZS = c(13.5054687, 14.7608697, 14.1115876, 13.3389063, 12.9048351), year = c(2007, 2006, 2005, 2004, 2003)), .Names = c("country", "NY.GNS.ICTR.GN.ZS", "year"), row.names = c(NA, 5L), class = "data.frame"), structure(list( country = c("United States", "United States", "United States", "United States", "United States"), NE.TRD.GNFS.ZS = c(29.3459277, 28.352838, 26.9861939, 25.6231246, 23.6615328), year = c(2007, 2006, 2005, 2004, 2003)), .Names = c("country", "NE.TRD.GNFS.ZS", "year"), row.names = c(NA, 5L), class = "data.frame"), structure(list( country = c("United States", "United States", "United States", "United States", "United States"), NY.GDP.MKTP.CD = c(1.37416e+13, 1.31165e+13, 1.23641e+13, 1.16309e+13, 1.0908e+13), year = c(2007, 2006, 2005, 2004, 2003)), .Names = c("country", "NY.GDP.MKTP.CD", "year"), row.names = c(NA, 5L), class = "data.frame"))

  • Zend Framework how to echo value of SUM query

    - by Rick de Graaf
    Hello, I created a query for the zend framework, in which I try to retrieve the sum of a column, in this case the column named 'time'. This is the query I use: $this->timequery = $this->db_tasks->fetchAll($this->db_tasks->select()->from('tasks', 'SUM(time)')->where('projectnumber =' . $this->value_project)); $this->view->sumtime = $this->timequery; Echoing the query tells me this is right. But I can't echo the result properly. Currently I'm using: echo $this->sumtime['SUM(time)']; Returning the following error: Catchable fatal error: Object of class Zend_Db_Table_Row could not be converted to string in C:\xampp\htdocs\BManagement\application\views\scripts\tasks\index.phtml on line 46 Line 46 being the line with the echo in my view. I've been searching now for two days on how to figure this out, or achieve the same result in a different way. Tried to serialize the value, but that didn't work either. Is there somebody who knows how to achieve the total sum of a database column? Any help is greatly appriciated! note: Pretty new to zend framework...

  • log4net from embedded xml?

    - by sanjeev40084
    i have two projects in visual studio. One is the console project while other is regular c# project. In the regular c# project, i have added config file(i.e. Test.config) with log4net section. This file is embedded. <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections> <log4net> <appender name="fileAppender" type="log4net.Appender.RollingFileAppender"> <file value="log//testapp.log" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="100MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.PatternLayout,log4net"> <param name="ConversionPattern" value="%d{ISO8601} [%t] [%-5p] %c - %m%n" /> </layout> </appender> <!-- Setup the root category, add the appenders and set the default priority --> <root> <priority value="ALL" /> <appender-ref ref="fileAppender" /> </root> </log4net> Now in my console project, i want to tell my log4net to load log4net information from (Test.config) which is in another project. This is what i did in the constructor of console project: Assembly asm = Assembly.GetExecutingAssembly(); Stream xmlStream = asm.GetManifestResourceStream("Northwind.Participant.Config.Test.config"); ILog log = LogManager.GetLogger(typeof(ConsoleStart)); 'Northwind.Participant is full namespace. Config - folder where Test.config file is situated. Does anyone know how i can do that?

  • Enable/disable RequiredValidator on client-side / CustomValidator not firing

    - by Simeon
    I've got a drop-down where the user selects a Country. It is a required "field". Next to it, there is a textfield named State. If the user selects US, then the field State is required. If the user selects e.g. Sweden, the State is not required, since Sweden has no states. Example code: <asp:DropDownList runat="server" ID="Country"></asp:DropDownList> <asp:RequiredFieldValidator ControlToValidate="Country" runat="server" Display="Static" ErrorMessage="Required field" /> <asp:TextBox runat="server" ID="State"></asp:TextBox> <asp:CustomValidator ClientValidationFunction="DoesntGetFiredIfStateIsEmpty" runat="server" Display="Static" ErrorMessage="Required field" /> <!-- SO, RATHER THIS TOGETHER WITH CONDITIONAL FIRING --> <asp:RequiredFieldValidator ControlToValidate="State" runat="server" Display="Static" ErrorMessage="Required field" /> My question to you is: How can I make this CustomValidator fire validation when it is empty? Or put simplier: How can I make a RequiredValidator fire conditionally? Or simplest: How can I enable/disable a RequiredValidator on client-side?

  • Create inherited class from base class

    - by Raj
    public class Car { private string make; private string model; public Car(string make, string model) { this.make = make; this.model = model; } public virtual void Display() { Console.WriteLine("Make: {0}", make); Console.WriteLine("Model: {0}", model); } public string Make { get{return make;} set{make = value;} } public string Model { get{return model;} set{model = value;} } } public class SuperCar:Car { private Car car; private int horsePower; public SuperCar(Car car) { this.car = car; } public int HorsePower { get{return horsePower;} set{horsepower = value;} } public override void Display() { base.Display(); Console.WriteLine("I am a super car"); } When I do something like Car myCar = new Car("Porsche", "911"); SuperCar mySupcar = new SuperCar(myCar); mySupcar.Display(); I only get "I am a supercar" but not the properties of my base class. Should I explicitly assign the properties of my base class in the SuperCar constructor? In fact I'm trying Decorator pattern where I want a class to add behaviour to a base class.

  • MonoDevelop 2.8.2: Build failed. Illegal characters in path

    - by user1056607
    I have just installed MonoDevelop 2.8.2. After opening a new solution named test I attempted to run the project. I push f5 and all I see is a "Build failed. Illegal characters in path" error in the bottom left. I open up the Error List and see no errors. I have done some searching and only find solutions pertaining to projects that are beyond the scope of just the pre-generated code. This is the code: using System; namespace Test { class MainClass { public static void Main(string[] args) { Console.WriteLine("Hello World!"); } } } I have tried to uninstall/reinstall, cut out any spaces in the path to the program or the solution, and even opened VS2010 and just copy pasted that code over. I've looked over my options under tools, solution options under project, and the project's options. I am running MD 2.8.2 with GTK# and Microsoft's .NET runtime. Let me know if you need anymore information. Any help would be appreciated. Thank you for your time!
