it helps some times The issue here isn't Vala or Glib, but how standard out works. A printf will print nothing to the screen unless there's a newline character in there.
Just change the printf line to:

AS3 ENTER_FRAME event still firing when frame changed

Any of those help You can add an event listener to a MovieClip , but you shouldn't do it as a static function , like in your example. The following should work...

code :

  private var ui:StatsUI = new StatsUI();

  public function view_stats(e:MouseEvent):void
  {
     // Event
     ui.addEventListener(Event.ENTER_FRAME,stats_scroll);
  }

  public function view_stats_exit (e:MouseEvent):void
  {
     ui.removeEventListener(Event.ENTER_FRAME,stats_scroll);
     view_start(null);
  }

Text Changed Event Not Firing

I wish this help you 1. You need to set AutoPostBack property of the TextBox to True .
2. while comparing the input String with EmptyString, you need to Trim the input so that whitespaces would be removed.

code :

<asp:TextBox ID="TxtComments" runat="server" OnTextChanged="TxtComments_TextChanged"   
AutoPostBack="True"></asp:TextBox>

   protected void TxtComments_TextChanged(object sender, EventArgs e)
    {
        if (TxtComments.Text.Trim().Equals(""))
        {
            LblErr.Text = "Please Enter a Comment!!!";
            LblErr.Visible = true;
            BtnSave.Enabled = false;
            BtnSave.BackColor = Color.LightGray;
            BtnSave.ForeColor = Color.Red;
        }    
        else
        {
            BtnSave.Enabled = true;
            BtnSave.BackColor = ColorTranslator.FromHtml("#666666");
            BtnSave.ForeColor = Color.White;
        }
    }

 protected void TxtComments_TextChanged(object sender, EventArgs e)
    {
        if (String.IsNullOrWhiteSpace(TxtComments.Text))
        {
            LblErr.Text = "Please Enter a Comment!!!";
            LblErr.Visible = true;
            BtnSave.Enabled = false;
            BtnSave.BackColor = Color.LightGray;
            BtnSave.ForeColor = Color.Red;
        }    
        else
        {
            BtnSave.Enabled = true;
            BtnSave.BackColor = ColorTranslator.FromHtml("#666666");
            BtnSave.ForeColor = Color.White;
        }
    }

protected void BtnSave_Click(object sender, EventArgs e)
{
   if (TxtComments.Text.Trim().Equals(""))
    {
        LblErr.Text = "Please Enter a Comment!!!";
        LblErr.Visible = true;
        BtnSave.Enabled = false;
        BtnSave.BackColor = Color.LightGray;
        BtnSave.ForeColor = Color.Red;
    }    
   else if (DrpForYear.SelectedItem.Text == "Please Select" || DrpForMonth.SelectedItem.Text == "Please Select" || RadView.SelectedItem.Text == "")
    {
        LblErr.Text = "Invalid Selection!!!";
        LblErr.Visible = true;
        BtnSave.Enabled = false;
        BtnSave.BackColor = Color.Gray;
        BtnSave.ForeColor = Color.Red;
    }

    else
    {
          /*your code*/
    }
  }

ObservableCollection Collection Changed event not firing

this will help When I run in to this the easiest way to solve it is just subscribe manually at the start.

code :

public FTViewModel(int JobID)
{
    _windowCloseAction = new DelegateCommand(OnWindowClose);
    _oFTrn = new ObservableFilesTransmitted(_dataDc, JobID);
    foreach(var item in _oFTrn)
    {
        item.PropertyChanged += FilesTransmitted_PropertyChanged;
    }
    _oFTrn.CollectionChanged += oFTrnCollectionChanged;
}

public FTViewModel(int JobID)
{
    _windowCloseAction = new DelegateCommand(OnWindowClose);
    _oFTrn = new ObservableFilesTransmitted(_dataDc, JobID);
    _oFTrn.CollectionChanged += oFTrnListChanged;
}

void oFTrnListChanged(object sender, ListChangedEventArgs e)
{
    if (e.ListChangedType == ListChangedType.ItemChanged)
    {
        if (e.PropertyDescriptor.Name == "DocumentNumber")
        {
            _filesTransmittedChange = true;
        }
    }
    _refreshViews = true;
}

G_LOCK behavior changed from glib 2.46 to glib 2.48?

By : the_Promise_LAN

Date : March 29 2020, 07:55 AM

seems to work fine Firstly, all that G_LOCK_DEFINE does is create a GMutex variable, who's name encodes the name of the variable that it's protecting e.g. G_LOCK_DEFINE(mSomeCounter) becomes GMutex g__mSomeCounter_lock;. So we can expand your code to something like:

code :

class CSomeClass {
    private:
        gulong mSomeCounter;
        GMutex g__mSomeCounter_lock;

    public:
        CSomeClass ();
};

CSomeClass::CSomeClass()
{
    g_mutex_lock(&g__mSomeCounter_lock);
    mSomeCounter = 0;
    g_mutex_unlock(&g__mSomeCounter_lock);
}

    CSomeClass::CSomeClass() : mSomeCounter(0)

CSomeClass::CSomeClass()
{
    g_mutex_init(&G_LOCK_NAME(mSomeCounter));
    G_LOCK(mSomeCounter);
    mSomeCounter = 0;
    G_UNLOCK(mSomeCounter);
}

main() {
    { CSomeClass class1; }
    { CSomeClass class2; }
    { CSomeClass class3; }
}

class CGMutex {
    GMutex    mutex;

    public:
    CGMutex() {
        g_mutex_init(&mutex);
    }

    ~CGMutex() {
        g_mutex_clear(&mutex);
    }

    GMutex *operator&() {
        return &mutex;
    }
};

class CGMutexLocker {
    CGMutex &mRef;
    public:
    CGMutexLocker(CGMutex &mutex) : mRef(mutex) {
        g_mutex_lock(&mRef);
    }
    ~CGMutexLocker() {
        g_mutex_unlock(&mRef);
    }
};

class CSomeClass {
    private:
        gulong mSomeCounter;
        CGMutex mSomeCounterLock;

    public:
        CSomeClass ();
};

CSomeClass::CSomeClass()
{
    CGMutexLocker locker(mSomeCounterLock); // lock the mutex using the locker
    mSomeCounter = 0;
}

WPF Text Changed Event Not Firing on 'S'

I wish did fix the issue. I suspect that you've subscribed for the TextChanged event. If that is the case just subscribe for PreviewKeyDown, apply your filter and set e.Handled to true to sink it.

code :

private void PreviewKeyDownFilter(object sender, KeyEventArgs e)
{
    if (e.Key == Key.S && Keyboard.IsKeyDown(Key.LeftShift))
        e.Handled = true;
}
