Program:-

Imports System.IO

Public Class slip20

    Dim path As String

    Private Sub FontStyleToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles FontStyleToolStripMenuItem.Click

        FontDialog1.ShowDialog()

        RichTextBox1.Font = FontDialog1.Font

    End Sub

    Private Sub FontColorToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles FontColorToolStripMenuItem.Click

        ColorDialog1.ShowDialog()

        RichTextBox1.ForeColor = ColorDialog1.Color

    End Sub

    Private Sub SaveToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles SaveToolStripMenuItem.Click

        If DialogResult.OK = SaveFileDialog1.ShowDialog() Then   ' To check file name is valid or not

            path = SaveFileDialog1.FileName

            RichTextBox1.SaveFile(path, RichTextBoxStreamType.PlainText)

            MsgBox("File save successfully.........")

        End If

       End Sub

    Private Sub OpenToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles OpenToolStripMenuItem.Click

        If DialogResult.OK = OpenFileDialog1.ShowDialog() Then   ' To check file name is valid or not

            path = OpenFileDialog1.FileName

            RichTextBox1.Text = (File.ReadAllText(path)).ToString

            MsgBox("File Open successfully.........")

        End If

    End Sub

End Class

Output:-


Design:-

1) Take RichTextBox, MenuStrip, FontDialog, ColorDialog, OpenFileDialog, SaveFileDialog on         design form.

2) Set Menu on MenuStrip.

Theory:-

Imports System.IO - This class contains a File method which is used to read content from a file.

FontDialog1.ShowDialog() - It is use to Display fontDialog. Which helps to select particular font from dialogbox.

FontDialog1.Font - It returns selected Font.

 ColorDialog1.ShowDialog() - It is used to Display color Palette. Which helps to select a particular color from Palette.

ColorDialog1.Color - It returns selected color.

SaveFileDialog1.FileName - It returns filename with path.

RichTextBox1.SaveFile(path, RichTextBoxStreamType.PlainText) - This method save the file at given path and write a text into a file from RichTextBox.

(File.ReadAllText(path)).ToString - This File method is used to read text from a file in a byte. It needs to convert into the string.

Form:-

Program:-

Public Class slip19

    Dim a As String

    Private Sub CutToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles CutToolStripMenuItem.Click

        TextBox1.Cut()

    End Sub

    Private Sub CopyToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles CopyToolStripMenuItem.Click

        TextBox1.Copy()

    End Sub

    Private Sub PasteToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles PasteToolStripMenuItem.Click

        TextBox2.ReadOnly = False

        TextBox2.Paste()

        TextBox2.ReadOnly = True

    End Sub

    Private Sub CloseToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles CloseToolStripMenuItem.Click

        Me.Close()

    End Sub

End Class

Output:-


Design:-

1) Take TextBoxes, Menustrip on Design form.

2) Set Text on Label and Add menus on Menustrip.



 Form:-


Program:-

Public Class slip18

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim a, b As String

        If CheckBox1.Checked = True Then

            a = CheckBox1.Text

        ElseIf CheckBox2.Checked = True Then

            a = CheckBox2.Text

        ElseIf CheckBox3.Checked = True Then

            a = CheckBox3.Text

        End If

        If RadioButton1.Checked = True Then

            b = RadioButton1.Text

        ElseIf RadioButton2.Checked = True Then

            b = RadioButton2.Text

        ElseIf RadioButton3.Checked = True Then

            b = RadioButton3.Text

        End If

        MsgBox("Name : " + TextBox1.Text + " Qualification : " + a + " post: " + b)

    End Sub

End Class

Output:-



Design:-

1) Take Label, Checkboxes, RadioButtons, TextBox, GroupBoxes, and Button on Design Form.

2) Set Text to Labels and Checkboxes.

Form:-



Program:-

Public Class slip17

    Private Sub slip17_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        ComboBox1.Items.Add("BCA")

        ComboBox1.Items.Add("BSC")

        ComboBox1.Items.Add("MCA")

        SplitContainer1.Panel2.Hide()

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        SplitContainer1.Panel2.Show()

        Label26.Text = TextBox1.Text

        Label25.Text = TextBox2.Text

        Label24.Text = TextBox3.Text

        Label23.Text = ComboBox1.SelectedItem()

        If RadioButton1.Checked = True Then

            Label22.Text = RadioButton1.Text

        ElseIf RadioButton2.Checked = True Then

            Label22.Text = RadioButton2.Text

        End If

        Label21.Text = DateTimePicker1.Value

        Label20.Text = TextBox4.Text

        Label19.Text = TextBox5.Text

    End Sub

End Class

Output:-

Design:-

1) Take SplitContainer, Button, Labels, TextBoxes, DateTimepicker, Radio buttons on design form. (note - Instead of SplitContainer you can use GroupBox as well But you need to change a code bit. )

2) Set Text on Labels, Buttons, and Radio buttons.

3) On panel 1 arrange some labels as well as TextBoxes, Radio Buttons 

3) On panel 2 arrange All Labels for displaying information about the student.
