  • Capture Video in iPhone

    - by Timmi
    Hi, I used the following code to record video. UIImagePickerController *m_objpicker;=[[UIImagePickerController alloc] init]; m_objpicker.sourceType = UIImagePickerControllerSourceTypeCamera; m_objpicker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie]; // hide the camera controls //picker.showsCameraControls=NO; m_objpicker.delegate = self; //picker.allowsImageEditing = NO; m_objpicker.allowsEditing=NO; // and put our overlay view in //picker.cameraOverlayView=m_objOverlayView; [self presentModalViewController:m_objpicker animated:YES]; When we finish recording (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{ NSURL *m_objMediaURL=[info objectForKey:UIImagePickerControllerMediaURL]; [m_objpicker dismissModalViewControllerAnimated:YES]; } My doubt is, how to save the captured video to a location we specify. Also how to use UISaveVideoAtPathToSavedPhotosAlbum . What all things i need to change in my code so that i can save video to a specified location Thanks,

  • Data types for validation

    - by nevalu
    How to create a new data type which to can check/validate its schema when is created a new variable (of that type)? By example, to validate if a string has 20 characters, I tried: {{{ // Format: 2006-01-12T06:06:06Z func date(str string) { if len(str) != 20 { fmt.Println("error") } } var Date = date() type Account struct { domain string username string created Date } }}} but it faills because Date is not a type.

  • Have my UIPickerView having the same behavior than the keyboard.

    - by camilo
    Hi. So I have a UITableView where one of its rows is a UITextView. When the user is writing something to UITextView (using the keyboard) the user can scroll the tableview and select another cell. Everything works. When the user selects another cell, a datePicker appears, and the user can select a given date. I want the user to be able to scroll the tableView the same way like when the keyboard is on the screen. The problem here is that when I scroll with the picker, the table bounces back to the previous position (with some cells hidden by the picker). I assume that this happens because I add the picker to the main window, as a subview... but I'm honestly not sure... Where (and how) should I add my picker so that it "appears" where the keyboard appears? Not sure I was clear... Thanks a lot.

  • How to query by recent date and value in SQL?

    - by wsb3383
    I have a table with three columns: patient_id, obs_date, and weight_val. patient_id stores patient identification #, weight_val stores a weight value, and obs_date stores the date when the weight reading was taken. So, a patient can have many different weight readings at different dates. How do you write a query for: select all patients whose last weight reading is 120?

  • Multilingual dates in gridview

    - by Moox
    I'm replacing a website that was previously HTML only. I put a GridView on the French and the English page and I'm getting 2 fields: A date and a currency. For the date, I need to transform it into a long date format. The English part isn't very hard, but when I get to the French page, I can't transform it into a long date format with French words (i.e.:Mardi instead of Tuesday). Is there any way to format the string with French date words instead?

  • Memory leak in C++ program.

    - by lampshade
    What I have is a very crude linked list..THe problem for me is that I am getting a memory leak in the constructor or main. I think it is the constructor. I have not yet deleted the eventName varaible that I have allocated memory for. Could someone help please? :/ (This is not a homework question) class Event { private: char * eventName ; string userEvent; struct node { node(); node * nextByName; const char * eventName; }; node * headByName; public: Event(const char * eventName, const Date &myDate); Event(); virtual ~Event(); void insert(const char * eventName, const Date &myDate, const Time &myTime); void setEvent(); const char * const getEvent() const { return userEvent.c_str(); }; void displayByName(ostream& out) const; }; Event::Event(const char * eventName, const Date &myDate) : eventName(new char[strlen(eventName)+1]), headByName(NULL), userEvent("") { if (eventName) { size_t length = strlen(eventName) +1; strcpy_s(this->eventName, length, eventName); } else eventName = NULL; } Event::Event() : eventName(NULL), userEvent(NULL), headByName(NULL) { } Event::~Event() { node * temp_node = NULL; node * current_node = headByName; while ( current_node ) { temp_node = current_node->nextByName; delete current_node; current_node = temp_node; } } void Event::insert(const char * eventName, const Date &myDate, const Time &myTime) // when we insert we dont care about the time, just the name and the date { node * current_node = new node(); if ( headByName == NULL ) { headByName = current_node; headByName->eventName = eventName; } else { node * search_node = headByName; node * prev_node = NULL; while ( search_node != NULL ) { prev_node = search_node; search_node = search_node->nextByName; } if ( NULL == prev_node ) { headByName = current_node; } else { prev_node->nextByName = current_node; } current_node->nextByName = search_node; current_node->eventName = eventName ; } } void Event::displayByName(ostream& out) const { cout << "Scheduled Events are: " << endl << endl; node * current_node = headByName; while ( current_node ) { (char*)eventName = (char*)current_node->eventName; out << eventName << endl; current_node = current_node->nextByName; } } Event::node::node() : nextByName(NULL), eventName(NULL) { } void Event::setEvent() { cout << "\n\nEnter a new event!

  • Weird fluctuating time on a XEN linux guest

    - by Vin-G
    I have a weird problem with some servers here at work. We have a few XEN guests who's current time fluctuates. # date;date;date;date;date;date;date Thu Feb 25 16:00:40 PHT 2010 Thu Feb 25 16:00:48 PHT 2010 Thu Feb 25 16:00:40 PHT 2010 Thu Feb 25 16:00:48 PHT 2010 Thu Feb 25 16:00:40 PHT 2010 Thu Feb 25 16:00:48 PHT 2010 Thu Feb 25 16:00:40 PHT 2010 As seen above, the time fluctuates between 16:00:48 and 16:00:40, which is problematic for us since computing for time differences in some of our scripts becomes inaccurate (ex. what should be a few ms differences becomes some few second differences, and even sometimes, negative differences). The problematic servers are linux guests on a XEN host. The time fluctuates on the guest systems, but it is okay in the host itself. I've ruled out ntpd since this happens irregardless of whether ntpd is running or not on the guest systems. Guest is on full virtualisation. The time on both the host and the guest does match except that the time in the guest fluctuates at about a few seconds from the host's time, and the host time does not fluctuate. /proc/sys/xen/independent_wallclock is 0 in the host and does not exist in the guest. Ntpd service was stopped and disabled. Setting independent_wallclock to 1 in the host has no effect (that is, time still fluctuates in the guest). Though I was not able to restart the guest as it is a production server. Might be able to do that over the weekend. Any ideas on what to check and how to resolve this problem?

  • How to change the Struts2 validation error message in the case of an invalid field value?

    - by FarmBoy
    I'm using Struts2 validation on a web form. In the case that a field is suppose to be an integer or Date, the <s:fielderror> message I receive is a generic Invalid field value for field "[fieldname]" Naturally, I want to customize this for the user. Here's an example validation: <field name="spouseDOB"> <field-validator type="date"> <message>"Spouse Date of Birth" is invalid.</message> </field-validator> <field-validator type="date"> <param name="min">01/01/1900</param> <message>"Spouse Date of Birth" must be after 1900 AD. </field-validator> </field> The message "Spouse Date of Birth" is invalid. never appears, for any invalid date that I have tried. The output is the generic Invalid field value for field spouseDOB spouseDOB is a java.util.Date object in the action class. It is set by a <s:textfield> in the JSP.

  • Core Data ANY BETWEEN predicate

    - by Mike Weller
    I'm trying to create an NSPredicate to find 'projects' that contain 'sessions' within a certain date range. I tried this at first: [NSPredicate predicateWithFormat:@"ANY sessions.date BETWEEN {$STARTDATE, $ENDDATE}"]; But I get an exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'to-many key not allowed here' It seems BETWEEN does not work with ANY in this way. I'm also limited in use of () and AND clauses meaning I can't use something like: [NSPredicate predicateWithFormat:@"ANY (sessions.date > $STARTDATE && sessions.date < $ENDDATE)"]; If I try that I get a parse error. How can I do this? Thanks UPDATE: Note that this: [NSPredicate predicateWithFormat:@"ANY sessions.date > $STARTDATE && ANY sessions.date < $ENDDATE"]; Is incorrect because it returns a project where there is a session greater than the start date and another session less than the end date but no session in between.

  • Add new types to Go

    - by nevalu
    I'm trying add new types for that been managed/used as in Go core types. To create new types is anything very interesting to validate data before of send it to a non-SQL DBMS or to check data from a form. Go uses univeral constants to define them at global level: var DateType = universe.DefineType("date", universePos, &dateType{}) In this case they're defined to be called from a package like types: var Date = &dateType{} I get these errors: test.go:58: o.lit undefined (cannot refer to unexported field lit) test.go:62: *dateType is not Type missing Pos() token.Position The code is based on: http://github.com/tav/go/blob/master/src/pkg/exp/eval/value.go http://github.com/tav/go/blob/master/src/pkg/exp/eval/type.go package main import ( "exp/eval" "fmt" // "go/token" ) // http://github.com/tav/go/blob/master/src/pkg/exp/eval/value.go type DateValue interface { eval.Value Get(*eval.Thread) string Set(*eval.Thread, string) } /* Date */ type dateV string func (v *dateV) String() string { return fmt.Sprint(*v) } func (v *dateV) Assign(t *eval.Thread, o eval.Value) { *v = dateV(o.(DateValue).Get(t)) } func (v *dateV) Get(*eval.Thread) string { return string(*v) } func (v *dateV) Set(t *eval.Thread, x string) { *v = dateV(x) } // http://github.com/tav/go/blob/master/src/pkg/exp/eval/type.go type Type interface { eval.Type // isDate returns true if this is a date type. isDate() bool } /* Common type */ type commonType struct{} // added func (commonType) isDate() bool { return false } /* Date */ type dateType struct { commonType } // * It should not be an universal constant //var universePos = token.Position{"<universe>", 0, 0, 0} // added //var DateType = universe.DefineType("date", universePos, &dateType{}) var Date = &dateType{} func (t *dateType) compat(o Type, conv bool) bool { t2, ok := o.lit().(*dateType) return ok && t == t2 } func (t *dateType) lit() Type { return t } func (t *dateType) isDate() bool { return true } func (t *dateType) String() string { return "<date>" } func (t *dateType) Zero() eval.Value { res := dateV("") return &res } /* Named types */ /* type NamedType struct { eval.NamedType Def Type }*/ type NamedType struct { // added // token.Position Name string // Underlying type.

  • jQuery UI Datepicker - Disable specific days

    - by Sam
    Is there any (easy) way to set the jQuery UI Datepicker to disallow selection of specific, predetermined days? I was able to get this approach working, however, it produces a null error which prevents it from displaying in IE. 'natDays[...].0' is null or not an object Thanks in advance! UPDATE: Might help if I included some code, right? Anyway, most of this was taken straight from the aforementioned thread: natDays = [ [7, 23], [7, 24], [8, 13], [8, 14], ]; function nationalDays(date) { for (i = 0; i < natDays.length; i++) { if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) { return [false, natDays[i][2] + '_day']; } } return [true, '']; } function noWeekendsOrHolidays(date) { var noWeekend = $.datepicker.noWeekends(date); if (noWeekend[0]) { return nationalDays(date); } else { return noWeekend; } } $(function() { $("#datepicker").datepicker({ inline: true, minDate: new Date(2009, 6, 6), maxDate: new Date(2009, 7, 14), numberOfMonths: 2, hideIfNoPrevNext: true, beforeShowDay: $.datepicker.noWeekends, altField: '#alternate', }); }); Thanks again!

  • HTML Calendar form and input arrays

    - by Christopher Ickes
    Hello. Looking for the best practice here... Have a form that consists of a calendar. Each day of the calendar has 2 text input fields - customer and check-in. What would be the best & most efficient way to send this form to PHP for processing? <form action="post"> <div class="day"> Day 1<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> <div class="day"> Day 2<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> </form> Is my current setup good? I feel there has to be a better option. My concern involves processing a whole year at once (which can happen) and adding additional text input fields.

  • @PrePersist with entity inheritance

    - by gerry
    I'm having some problems with inheritance and the @PrePersist annotation. My source code looks like the following: _the 'base' class with the annotated updateDates() method: @javax.persistence.Entity @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public class Base implements Serializable{ ... @Id @GeneratedValue protected Long id; ... @Column(nullable=false) @Temporal(TemporalType.TIMESTAMP) private Date creationDate; @Column(nullable=false) @Temporal(TemporalType.TIMESTAMP) private Date lastModificationDate; ... public Date getCreationDate() { return creationDate; } public void setCreationDate(Date creationDate) { this.creationDate = creationDate; } public Date getLastModificationDate() { return lastModificationDate; } public void setLastModificationDate(Date lastModificationDate) { this.lastModificationDate = lastModificationDate; } ... @PrePersist protected void updateDates() { if (creationDate == null) { creationDate = new Date(); } lastModificationDate = new Date(); } } _ now the 'Child' class that should inherit all methods "and annotations" from the base class: @javax.persistence.Entity @NamedQueries({ @NamedQuery(name=Sensor.QUERY_FIND_ALL, query="SELECT s FROM Sensor s") }) public class Sensor extends Entity { ... // additional attributes @Column(nullable=false) protected String value; ... // additional getters, setters ... } If I store/persist instances of the Base class to the database, everything works fine. The dates are getting updated. But now, if I want to persist a child instance, the database throws the following exception: MySQLIntegrityConstraintViolationException: Column 'CREATIONDATE' cannot be null So, in my opinion, this is caused because in Child the method "@PrePersist protected void updateDates()" is not called/invoked before persisting the instances to the database. What is wrong with my code?

  • Android ArrayList<Location> passing between activities

    I have simple class Track, which stores information about route: import java.io.Serializable; import java.util.ArrayList; import java.util.Date; import android.location.Location; public class Track implements Serializable { private static final long serialVersionUID = -5317697499269650204L; private Date date; private String name; private int time; private double distance, speed; private ArrayList<Location> route; public Track(String name, int time, double distance, ArrayList<Location> route) { this.date = new Date(); this.name = name; this.time = time; this.distance = distance; this.speed = distance / (time / 3600.); this.route = route; } public String getDate() { return String.format("Date: %1$td-%1$tb-%1$tY%nTime: %1$tH:%1$tM:%1$tS", date); } public String getName() { return name; } public int getTime() { return time; } public double getDistance() { return distance; } public float getSpeed() { return (float) speed; } public ArrayList<Location> getRoute() { return route; } @Override public String toString() { return String.format("Name: %s%nDate: %2$td-%2$tb-%2$tY%nTime: %2$tH:%2$tM:%2$tS", name, date); } } And I'm passing it from one activity to another: Intent showTrackIntent = new Intent(TabSavedActivity.this, ShowTrackActivity.class); showTrackIntent.putExtra("track", adapter.getItem(position)); startActivity(showTrackIntent); Where (Track object is element on ListView). I get error during passing Track object: java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = classes.Track) What is happening?

  • How to use linux csplit to chop up massive XML file?

    - by Fred
    Hi everyone, I have a gigantic (4GB) XML file that I am currently breaking into chunks with linux "split" function (every 25,000 lines - not by bytes). This usually works great (I end up with about 50 files), except some of the data descriptions have line breaks, and so frequently the chunk files do not have the proper closing tags - and my parser chokes halfway through processing. Example file: (note: normally each "listing" xml node is supposed to be on its own line) <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks that screw the split function</desc><more_tags>stuff</more_tags></listing> </listings> Then sometimes my split ends up like <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks ... EOF So - I have been reading about "csplit" and it sounds like it might work to solve this issue. I cant seem to get the regular expression right... Basically I want the same output of ~50ish files Something like: *csplit -k myfile.xml '/</listing>/' 25000 {50} Any help would be great Thanks!
