Visual Basic 10 Scientific Calculator Code [ Edge ]

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

Private Sub btn8_Click(sender As Object, e As EventArgs) Handles btn8.Click txtDisplay.Text &= "8" End Sub

Private Sub btnEquals_Click(sender As Object, e As EventArgs) Handles btnEquals.Click Try Dim result As Double = EvaluateExpression(txtDisplay.Text) txtDisplay.Text = result.ToString() Catch ex As Exception txtDisplay.Text = "Error" End Try End Sub

Private Sub btn3_Click(sender As Object, e As EventArgs) Handles btn3.Click txtDisplay.Text &= "3" End Sub Visual Basic 10 Scientific Calculator Code

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

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

In this article, we will provide a comprehensive guide on creating a scientific calculator using Visual Basic 10. The calculator will have the ability to perform basic arithmetic operations, trigonometric functions, exponential functions, and logarithmic functions. Private Sub btn5_Click(sender As Object, e As EventArgs)

Private Sub btnLog_Click(sender As Object, e As EventArgs) Handles btnLog.Click Try Dim result As Double = Math.Log(Convert.ToDouble(txtDisplay.Text)) txtDisplay.Text = result.ToString() Catch ex As Exception txtDisplay.Text = "Error" End Try End Sub

Private Sub btnCos_Click(sender As Object, e As EventArgs) Handles btnCos.Click Try Dim angle As Double = Convert.ToDouble(txtDisplay.Text) Dim result As Double = Math.Cos(angle * Math.PI / 180) txtDisplay.Text = result.ToString() Catch ex As Exception txtDisplay.Text = "Error" End Try End Sub

Private Sub btn6_Click(sender As Object, e As EventArgs) Handles btn6.Click txtDisplay.Text &= "6" End Sub Private Sub btnLog_Click(sender As Object, e As EventArgs)

Private Sub btnSin_Click(sender As Object, e As EventArgs) Handles btnSin.Click Try Dim angle As Double = Convert.ToDouble(txtDisplay.Text) Dim result As Double = Math.Sin(angle * Math.PI / 180) txtDisplay.Text = result.ToString() Catch ex As Exception txtDisplay.Text = "Error" End Try End Sub

Below is the complete code for the scientific calculator:

The scientific calculator will have a user-friendly interface with buttons for digits 0-9, four arithmetic operations (+, -, *, /), and various scientific functions (sin, cos, tan, exp, log, etc.). The calculator will display the results in a text box.

In this article, we provided a comprehensive guide on creating a scientific calculator using Visual Basic 10. The calculator has a user-friendly interface and can perform basic arithmetic operations and various scientific functions. The code provided can be modified and extended to create more complex calculators.
