How do you make a pop-up messagebox by pressing a button in visual basic?

Answer 1

Example:

MsgBox("This is an example!", MsgBoxStyle.Information, "Example")

or:

MsgBox("This is an example!", MsgBoxStyle.Exclamation, "Example")

or:

MsgBox("This is an example!", MsgBoxStyle.Critical, "Example")

you can choose between one of these three styles.

just add one of these in the line where you want it to be displayed like:

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

MsgBox("This is an example!", MsgBoxStyle.Information, "Example")

End Sub

Answer 2

Double click on the button

Type...

Msgbox("Your Message")
