How to keep a Form on top of others in VB.NET?

When we create a Windows application, we want to keep the main form on top of another form. We can also say that when the application starts, a popup window form is displayed on top of the main form within the application to start the further process. In VB6 we can see a Win32API that call SetWindowPos to set the form always on top. And in VB.NET, it is simple to keep a form at the top using the TopMost property of the form as True. After setting the TopMost property to true, the Uppermost form of a Windows application that overlaps all other forms, even if the Uppermost form is not in the active or foreground form.

Furthermore, the TopMost property of the form will force the form to the top layer of the screen when the value of TopMost is true. And the Show() method is used to display the form in Windows Application.

The following syntax is used to set the form on top of others.

If we want to display a form on top of another form, we have to create two Windows Forms.

MainPage.vb
TopForm.vb

To keep the TopForm.vb Form on top of the MainPage.vb Form, we need to set the TopMost property in the MainPage.vb file to True.

MainPage.vb

  Public Class MainPage      Private Sub MainPage_Load(sender As Object, e As EventArgs) Handles MyBase.Load          Me.Text = “tutoraspire.com” ‘Set the title for a Window Form           Label1.Text = “Student Name”          Label2.Text = “Roll No.”          Button1.Font = New Font(“Microsoft Sans Serif”, 12)          Label3.Text = “Email ID”          Button1.Font = New Font(“Microsoft Sans Serif”, 12)          Label4.Text = “Course”          Button1.Font = New Font(“Microsoft Sans Serif”, 12)          Label5.Text = “Geder”          Button1.Font = New Font(“Microsoft Sans Serif”, 12)          Label6.Text = “Student Registration Details”          Label6.Font = New Font(“Microsoft Sans Serif”, 20)  ‘ Set Font style          Label6.ForeColor = Color.Red          RadioButton1.Text = “Male”  ‘ Set the radiobutton1 and radiobutton2          RadioButton2.Text = “Female”          Button1.Text = “Submit”          Button1.Font = New Font(“Microsoft Sans Serif”, 10)          Button1.BackColor = Color.Green          ‘ Define the parameter to set the TopForm on top of the MainPage Form.          Dim frm As New TopForm          frm.TopMost = True ‘Set the TopMost property to True          frm.Show() ‘Show() method is used to display the TopForm      End Sub      Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click          Dim name As String          Dim rollno As String          Dim email As String          Dim course As String          Dim gen As String          name = TextBox1.Text          rollno = TextBox2.Text          email = TextBox3.Text          course = TextBox4.Text          If RadioButton1.Checked = True Then              gen = “Male”          ElseIf RadioButton2.Checked = True Then              gen = “Female”          End If          ‘ Display the user details, when the Button1 is clicked          MsgBox(” Your Name: ” & name + vbCrLf + “Your Roll No: ” & rollno + vbCrLf +                 “Your Email: ” & email + vbCrLf + “Your Course: ” & course + vbCrLf + “Your Course: ” & gen)      End Sub  End Class  

TopForm.vb

  Public Class TopForm      Private Sub TopForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load            PictureBox1.BackgroundImage = Image.FromFile(“C:UsersAMIT YADAVDesktopJTP.png”)          PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage      End Sub  End Class
