Questions[windows-forms]

I have a peculiar problem, I have created a code to be able to organize and execute shortcuts, but my problem is with the OpenFileDialog Class.

After having put a filter on it, so that it only finds .exe, it turns out that it is unable to differentiate between an .exe and a .url that imitates an .exe.

 OpenFileDialog file = new OpenFileDialog();
            file.Filter = "Executable (*.exe)|*.exe";
            if (file.ShowDialog() == DialogResult.OK && file.CheckPathExists && file.CheckFileExists)
            {
                textResult.ReadOnly = false;
                textResult.Text = System.IO.Path.GetFullPath(file.FileName);
                textResult.ReadOnly = true;
            }

In the image set as despite the .exe filter, it shows both the direct access of the .exe and that of a url and if you select the one of the url, "Catastrophic failure" appears.

Any ideas?.

I have this form to upload a txt file:

Button code, this is where I upload the file:

private void button1_Click(object sender, EventArgs e)
{
    //lines contiene todas las lineas del archivo
    string[] lines = System.IO.File.ReadAllLines(@"C:\\Users\\JR\\Desktop\\TXTS\\MX19080253005013GNNPN8ACYN.htd");


    //estamos mandando las lineas a una cadena string a la clase read
    r.lineas = lines;
    //estamos llenando la el grid con la informacion 
    r.readFile(dataGridView1, ' ');

}

Result:

I have this read class:

class read
    {
        public string[] lineas; //creamos una cadena de string 

        public void readFile(DataGridView tabla, char caracter) //metodo para leer y llenar el grid 
        {


            foreach (var linea in lineas) //mandamos la informacion y la muestra en el grid
            {

                int columnas = tabla.Columns.Count;

                foreach (DataGridViewRow fila in tabla.Rows)
                {

                    int vacios = 0;

                    for (int i = 0; i < columnas; i++) //quitar espacios
                    {
                        if (Convert.ToString(fila.Cells[i].Value) == string.Empty)
                        {
                                vacios++;
                        }
                    }

                    if (vacios == columnas)
                    {
                        tabla.Rows.RemoveAt(fila.Index);
                    }
                }
                AddRowDataGrid(tabla,linea,caracter);

            }

        } //public readFile

        public static void nombrarTitulo(DataGridView tabla, string [] titulos)
        {
            int x = 0;
            for (x = 0; x <= tabla.ColumnCount - 1; x++ )
            {
                    tabla.Columns[x].HeaderText = titulos[x];
            }
        } // public nombrarTitulo


        public static void AddRowDataGrid(DataGridView tabla, string linea, char caracter)
        {

            string[] arreglo = linea.Split(new string[] { caracter.ToString(),"\t" }, StringSplitOptions.RemoveEmptyEntries);

            tabla.Rows.Add(arreglo);

        } //public AddRowGrid 
    }

This is what the txt file looks like:

This is line 4:

What I need to do is obtain the information of each one, that is, 3/7/2019 from Date:, 6:42 AM from TIME: etc... and put them in the form where there are some labels which will be filled with said information, the name of these are:

labelDate

LabelTime LabelSn

LabelSw

LabelStation

LabelTx

How can I perform this action?

I have a project but it is in Windows Form and I am a beginner in that environment. I have the following code to try to read data from an RFID proximity card reader and show the ID of said card in a textbox, the reader is connected by USB, I would like to know if someone can help me.

    namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {

        private SerialPort RFID;

        public Form1()
        {
            InitializeComponent();

            SerialPort serialPort = new SerialPort();
            RFID = serialPort;
            RFID.PortName = "COM1";
            RFID.BaudRate = 9600;
            RFID.DataBits = 8;
            RFID.Parity = Parity.None;
            RFID.StopBits = StopBits.One;
            RFID.Open();
            RFID.DataReceived += new SerialDataReceivedEventHandler(RFID_DataReceived);
            prueba();
        }


        private void prueba()
        {
            textBox2.Text = "test";
        }

        private void RFID_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            MessageBox.Show("Inica Componentes");
            string data = RFID.ReadExisting();
            textBox2 .Text = "77777";
        }

       }
    }

How are you?

I want to hide the ribbon of my reports when executing them but I don't know how to do it.

Does anyone know how?
