Fran Pino's questions

I would like to be able to move in Xamarin through different Activities, from the MainActivity from a button I can go to the following activity (MenuNumbers):

 base.OnCreate(bundle);

        SetContentView(Resource.Layout.Main);

        Button button = FindViewById<Button>(Resource.Id.btnNumeros);
        button.Click += delegate
        {
            SetContentView(Resource.Layout.MenuNum);

        };            

But from this activity I need to go back to a third activity that I can't get it to work for me, I do it from the btnSequential button and the new activity is called Sequential:

 base.OnCreate(savedInstanceState);

        SetContentView(Resource.Layout.MenuNum);

        Button button = FindViewById<Button>(Resource.Id.btnSecuencial);
        button.Click += delegate
        {
            SetContentView(Resource.Layout.Secuencial);

        };

What am I doing wrong?

Thank you very much

I have a form with several controls, label, textBox, etc. I need to resize all the controls when the form is resized and it seems that I have achieved it, but even if the controls are resized, the size of their font does not seem to change, it stays the same size so it does not adapt, how can I do so that the size of my label, textbox etc adapt to the size of the control itself? My code is:

public partial class Marcador : Form
    {
        private Rectangle pictureBoxLocal;
        private Rectangle pictureBoxVisit;
        private Rectangle txtPuntosLocal;
        private Rectangle txtPuntosVisit;
        private Rectangle lblNomLocal;
        private Rectangle lblNomVisit;
        private Rectangle txtCrono;
        private Rectangle lblLetreroLocal;
        private Rectangle lblLetreroVisit;
        private Rectangle lblGuion;

        private Size formOriginalSize;

        public Marcador()
        { 
            InitializeComponent();
        }

        private void Marcador_Load(object sender, EventArgs e)
        {
            formOriginalSize = this.Size;

            pictureBoxLocal = new Rectangle(mPictureBoxLocal.Location.X, mPictureBoxLocal.Location.Y, mPictureBoxLocal.Width, mPictureBoxLocal.Height);
            pictureBoxVisit = new Rectangle(mPictureBoxVisit.Location.X, mPictureBoxVisit.Location.Y, mPictureBoxVisit.Width, mPictureBoxVisit.Height);
            txtPuntosLocal = new Rectangle(mTxtPuntosLocal.Location.X, mTxtPuntosLocal.Location.Y, mTxtPuntosLocal.Width, mTxtPuntosLocal.Height);
            txtPuntosVisit = new Rectangle(mTxtPuntosVisit.Location.X, mTxtPuntosVisit.Location.Y, mTxtPuntosVisit.Width, mTxtPuntosVisit.Height);
            lblNomLocal = new Rectangle(mLblNomLocal.Location.X, mLblNomLocal.Location.Y, mLblNomLocal.Width, mLblNomLocal.Height);
            lblNomVisit = new Rectangle(mLblNomVisit.Location.X, mLblNomVisit.Location.Y, mLblNomVisit.Width, mLblNomVisit.Height);
            txtCrono = new Rectangle(mTxtCrono.Location.X, mTxtCrono.Location.Y, mTxtCrono.Width, mTxtCrono.Height);
            lblLetreroLocal = new Rectangle(mLblLetreroLocal.Location.X, mLblLetreroLocal.Location.Y, mLblLetreroLocal.Width, mLblLetreroLocal.Height);
            lblLetreroVisit = new Rectangle(mLblLetreroVisit.Location.X, mLblLetreroVisit.Location.Y, mLblLetreroVisit.Width, mLblLetreroVisit.Height);
            lblGuion = new Rectangle(mLblGuion.Location.X, mLblGuion.Location.Y, mLblGuion.Width, mLblGuion.Height);
        }

        private void resizeChildrenControls()
        {
            resizeControl(pictureBoxLocal, mPictureBoxLocal);
            resizeControl(pictureBoxVisit, mPictureBoxVisit);
            resizeControl(txtPuntosLocal, mTxtPuntosLocal);
            resizeControl(txtPuntosVisit, mTxtPuntosVisit);
            resizeControl(lblNomLocal, mLblNomLocal);
            resizeControl(lblNomVisit, mLblNomVisit);
            resizeControl(txtCrono, mTxtCrono);
            resizeControl(lblLetreroLocal, mLblLetreroLocal);
            resizeControl(lblLetreroVisit, mLblLetreroVisit);
            resizeControl(lblGuion, mLblGuion);
        }
        private void resizeControl(Rectangle originalControlRect, System.Windows.Forms.Control control)
        {
            float xRatio = (float)(this.Width) / (float)(formOriginalSize.Width);
            float yRatio = (float)(this.Height) / (float)(formOriginalSize.Height);

            int newX = (int)(originalControlRect.X * xRatio);
            int newY = (int)(originalControlRect.Y * yRatio);
            int newWidth = (int)(originalControlRect.Width * xRatio);
            int newHeight = (int)(originalControlRect.Height * yRatio);

            control.Location = new Point(newX, newY);
            control.Size = new Size(newWidth, newHeight);
        }
 private void Marcador_Resize(object sender, EventArgs e)
        {
            resizeChildrenControls();
        }

to see if they could help me. I have two TextBox each in a different class, and I need what is typed in one to be displayed in the other.

The one that should receive the data I have it like this in xaml:

<TextBox x:Name="mTxtPuntosLocal" Text="{Binding AddPuntoLocal, ElementName=ventana}" HorizontalAlignment="Left"  TextWrapping="Wrap"  VerticalAlignment="Top" FontSize="100"  Background="{x:Null}" BorderBrush="{x:Null}"  Width="135"/>

Right now I take the data to prove that it receives like this:

string varPuntoLocal;       
        public string AddPuntoLocal
        {
            get
            {
                return  "3";
            }
            set
            {
                varPuntoLocal = value;
            }
        }

Right now I always get the "3". I need it to show me what is inside another textbox of another class, how I should reference it inside the Biding.

Thank you

You will see I have a webBroser to which I pass a url like this:

public Marcador()
    { 
        InitializeComponent();       
    }
public void playGol(String url)
    {          
        webBrowser1.Navigate(url);
    }

When I call the method playGol()from another form webBroser1it doesn't show me anything, a blank screen, however if I put the sentence: webBrowser1.Navigate("http://---");in the constructor the web loads me correctly, does anyone know why it happens? (The URL parameter gets the web address well)

Another thing is that I try to open a SWF and what it does is open Chrome and download the file, how can I make it open webBroserand not chrome and show me (not download) the SWF?

Thanks in advance

Edit: I call it from another form:

private void btnGol_Click(object sender, EventArgs e) 
{ 
Marcador marcador = new Marcador();
 marcador.playGol(@"C:\gol2.swf"); 
}

Does anyone know what they are and how to remove the buttons that are added by default when creating a WPF project ?

I attach an image with the buttons I am referring to:

In windows forms it does not appear only in WPF

Good afternoon, I have a Windows Media Player control in C# which opens the video but does not show an image, it appears with a black image, but the sound can be heard.

In the Designer window I have the following:

 private void InitializeComponent()
    {
        System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(FormVideo));
        this.wmPlayer = new AxWMPLib.AxWindowsMediaPlayer();
        ((System.ComponentModel.ISupportInitialize)(this.wmPlayer)).BeginInit();
        this.SuspendLayout();
        // 
        // wmPlayer
        // 
        this.wmPlayer.Dock = System.Windows.Forms.DockStyle.Fill;
        this.wmPlayer.Enabled = true;
        this.wmPlayer.Location = new System.Drawing.Point(0, 0);
        this.wmPlayer.Name = "wmPlayer";
        this.wmPlayer.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("wmPlayer.OcxState")));
        this.wmPlayer.Size = new System.Drawing.Size(736, 539);
        this.wmPlayer.TabIndex = 0;
        // 
        // FormVideo
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.AutoSize = true;
        this.BackColor = System.Drawing.SystemColors.ActiveCaptionText;
        this.ClientSize = new System.Drawing.Size(736, 539);
        this.Controls.Add(this.wmPlayer);
        this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        this.Name = "FormVideo";
        this.ShowIcon = false;
        this.ShowInTaskbar = false;
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
        ((System.ComponentModel.ISupportInitialize)(this.wmPlayer)).EndInit();
        this.ResumeLayout(false);

    }

Thanks.

They have asked me to do something simple in kinectbut in C#(I have been studying for 1 week C#since it is not my language).

Thanks to the codes that Microsoft shares when you install the SDK, I have the code where your kinect image appears and an image in the background.

Someone who controls C#or has worked with kinectthat I can guide me?

I've got:

public MainWindow()
    {
        // get the kinectSensor object
        this.kinectSensor = KinectSensor.GetDefault();

        // open the reader for the depth frames
        this.bodyIndexFrameReader = this.kinectSensor.BodyIndexFrameSource.OpenReader();

        // wire handler for frame arrival
        this.bodyIndexFrameReader.FrameArrived += this.Reader_FrameArrived;

        this.bodyIndexFrameDescription = this.kinectSensor.BodyIndexFrameSource.FrameDescription;

        // allocate space to put the pixels being converted
        this.bodyIndexPixels = new uint[this.bodyIndexFrameDescription.Width * this.bodyIndexFrameDescription.Height];

        // create the bitmap to display
        this.bodyIndexBitmap = new WriteableBitmap(this.bodyIndexFrameDescription.Width, this.bodyIndexFrameDescription.Height, 96.0, 96.0, PixelFormats.Bgr32, null);

        // set IsAvailableChanged event notifier
        this.kinectSensor.IsAvailableChanged += this.Sensor_IsAvailableChanged;

        // open the sensor
        this.kinectSensor.Open();

        // set the status text
        this.StatusText = this.kinectSensor.IsAvailable ? Properties.Resources.RunningStatusText
                                                        : Properties.Resources.NoSensorStatusText;

        // use the window object as the view model in this simple example
        this.DataContext = this;

        // initialize the components (controls) of the window
        this.InitializeComponent();

        //Inicializo el TIMER
         inicioTimer();

    }

When the application starts, a WPF is opened with an IMAGE object where what the KINECT shows appears, after the TIMER ends, a series of methods are started and I need the KINECT to start again, which method would I have to call from the what do I have in the MainWindow?

Thank you

I fill a list from a OpenFileDialogand put it in "file" and then put it in the list like this:

foreach (string file in selectedFiles)
{
    ListBoxItem lstItem = new ListBoxItem();
    lstItem.Content = file; //File es la cadena de la URL
    miLista.Items.Add(lstItem);
} 

What I assign to the ListBoxare URLtype

c:\user\paco\image1.jpg

c:\user\paco\image2.jpg

So far so good, but now I need to loop through that ListBoxand put its Items into aString[]

String[] matriz = new String[miLista.Items.Count];
foreach (Object index in miLista.Items)
{
    matriz = index.ToString().Split();
} 

In this way, what gets me in each index of the string[]is the following:

System.Windows.Controls.ListBoxItem: c:\user\cucumber\image1.jpg System.Windows.Controls.ListBoxItem: c:\user\cucumber\image2.jpg System.Windows.Controls.ListBoxItem: c:\user\cucumber \image3.jpg

What I need is only the URLand that it does not return the Type and the Value, I need to put String[]only the value in it.

I fill the ListBoxlike this:

OpenFileDialog myFD = new OpenFileDialog();
myFD.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);
myFD.Multiselect = true;
myFD.Title = "Seleccione uno o más archivos";
myFD.Filter = "Archivos imagen (*.jpg),(*.jpeg),(*.gif),(*.png)|*.jpg;*.jpeg;*.gif;*.png";

Nullable<bool> result = myFD.ShowDialog();
if (result == true)
{
    string[] selectedFiles = myFD.FileNames; // La propiedad FileNames (o FileName) almacena la ruta, nombre y extensión.
    foreach (string file in selectedFiles)
    {
        miLista.Items.Add(file);               
    }
    archivo.set_listaReproduccion(selectedFiles);
    archivo.grabar();
}
