Visual Basic 10 Scientific Calculator - Code

Public Class ScientificCalculator Private Sub btn0_Click(sender As Object, e As EventArgs) Handles btn0.Click txtDisplay.Text &= "0" End Sub

The code above creates a scientific calculator with buttons for digits 0-9, four arithmetic operations, and various scientific functions. When a button is clicked, the corresponding digit or operator is appended to the text box.

Private Function EvaluateExpression(expression As String) As Double Dim dataTable As New System.Data.DataTable() Dim result As Double = 0 Try result = dataTable.Compute(expression, String.Empty) Catch ex As Exception Throw ex End Try Return result End Function End Class

Private Sub btnTan_Click(sender As Object, e As EventArgs) Handles btnTan.Click Try Dim angle As Double = Convert.ToDouble(txtDisplay.Text) Dim result As Double = Math.Tan(angle * Math.PI / 180) txtDisplay.Text = result.ToString() Catch ex As Exception txtDisplay.Text = "Error" End Try End Sub Visual Basic 10 Scientific Calculator Code

Private Sub btn3_Click(sender As Object, e As EventArgs) Handles btn3.Click txtDisplay.Text &= "3" End Sub

Private Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.Click txtDisplay.Text &= "+" End Sub

Below is the complete code for the scientific calculator: Private Sub btnDivide_Click(sender As Object

The btnEquals_Click event handler evaluates the expression in the text box using the EvaluateExpression function, which uses a DataTable to compute the result.

Private Sub btnDivide_Click(sender As Object, e As EventArgs) Handles btnDivide.Click txtDisplay.Text &= "/" End Sub

Private Sub btn5_Click(sender As Object, e As EventArgs) Handles btn5.Click txtDisplay.Text &= "5" End Sub four arithmetic operations
