Please help! I'm a desperate VB beginner.... Im trying to make a Converter that adds, minuses, multiplies and divides Byte, Integer, Double, String. The four have an individual ComboBox so you can choose between +,-, *, \ I was going to do "Or" but I failed miserably. (ie. + or - or * or \) Here's the code so far.. Option Explicit On Option Strict On Public Class Converter Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click Dim byteA As Integer = 0 Dim byteB As Integer = 0 Dim byteTotal As Integer = 0 Dim integerA As Integer = 0 Dim integerB As Integer = 0 Dim integerTotal As Integer = 0 Dim doubleA As Double = 0.0 Dim doubleB As Double = 0.0 Dim doubleTotal As Double = 0.0 Dim stringA As Integer Dim stringB As Integer Dim stringTotal As Integer Dim grandTotal As Integer = 0 Dim isConverted As Boolean = False isConverted = Integer.TryParse(txtByte1.Text, byteA) isConverted = Integer.TryParse(txtByte2.Text, byteB) isConverted = Integer.TryParse(txttotalByte.Text, byteTotal) isConverted = Integer.TryParse(txtInteger1.Text, integerA) isConverted = Integer.TryParse(txtInteger2.Text, integerB) isConverted = Integer.TryParse(txttotalInteger.Text, integerTotal) isConverted = Double.TryParse(txtDouble1.Text, doubleA) isConverted = Double.TryParse(txtDouble2.Text, doubleB) isConverted = Double.TryParse(txttotalDouble.Text, doubleTotal) isConverted = Integer.TryParse(txtString1.Text, stringA) isConverted = Integer.TryParse(txtString2.Text, stringB) isConverted = Integer.TryParse(txttotalString.Text, stringTotal) If cboBoxByte.SelectedIndex <> -1 Then Select Case (cboBoxInteger.SelectedIndex) Case 1 byteTotal = byteA + byteB txttotalByte.Text = byteTotal.ToString Case 2 byteTotal = byteA - byteB txttotalByte.Text = byteTotal.ToString Case 3 byteTotal = byteA * byteB txttotalByte.Text = byteTotal.ToString Case 4 byteTotal = byteA \ byteB txttotalByte.Text = byteTotal.ToString End Select End If If cboBoxInteger.SelectedIndex <> -1 Then Select Case (cboBoxInteger.SelectedIndex) Case 1 integerTotal = integerA + integerB txttotalInteger.Text = integerTotal.ToString() Case 2 integerTotal = integerA - integerB txttotalInteger.Text = integerTotal.ToString() Case 3 integerTotal = integerA * integerB txttotalInteger.Text = integerTotal.ToString() Case 4 integerTotal = integerA \ integerB txttotalInteger.Text = integerTotal.ToString() End Select End If If cboBoxDouble.SelectedIndex <> -1 Then Select Case (cboBoxDouble.SelectedIndex) Case 1 doubleTotal = doubleA + doubleB txttotalDouble.Text = doubleTotal.ToString() Case 2 doubleTotal = doubleA - doubleB txttotalDouble.Text = doubleTotal.ToString() Case 3 doubleTotal = doubleA * doubleB txttotalDouble.Text = doubleTotal.ToString() Case 4 doubleTotal = CLng(doubleA) \ CLng(doubleB) txttotalDouble.Text = doubleTotal.ToString() End Select End If End Sub |
