  10. Next set specific properties for controls created:
  • First click on text box 1. Name it as “txtTempValue1”.
  • Then click on text box 2 and name it as “txtTempValue2”.
  • Next click on the label and set its caption as “=”.
  • Click on combo box 1 and name it as “cmbTempUnit1”.
  • And click on combo box 2 and name it as “cmbTempUnit2”.
  • Next click on command button 1 and name it as “btnConvert”. Set caption as “Convert”.
  • Click on command button 2 and name it as “btnClose”. Set its caption as “Close”.

Besides, set other properties if necessary.

Input Codes for Controls

  1. Double click on “Convert” button to enter code area. Paste following codes there:
Private Sub btnConvert_Click()
  Dim dTempValue1 As Double, dTempValue1InF As Double, dTempValue2 As Double
  Dim strTempUnit1 As String, strTempUnit2 As String
  strTempUnit1 = frmTemperatureConverter.cmbTempUnit1.Text
  strTempUnit2 = frmTemperatureConverter.cmbTempUnit2.Text
  dTempValue1 = CDbl(frmTemperatureConverter.txtTempValue1.Value)
  Select Case strTempUnit1
    Case "Celsius"
      dTempValue1InF = dTempValue1 * 33.8
    Case "Fahrenheit"
      dTempValue1InF = dTempValue1
    Case "Kelvin"
      dTempValue1InF = dTempValue1 * -457.87
    Case "Rankine"
      dTempValue1InF = dTempValue1 * -458.67
    Case "Delisle"
      dTempValue1InF = dTempValue1 * 1.2
    Case "Newton"
      dTempValue1InF = dTempValue1 * 102.414
    Case "Réaumur"
      dTempValue1InF = dTempValue1 * 34.25
    Case "Rømer"
      dTempValue1InF = dTempValue1 * 3.42857143
  End Select
  Select Case strTempUnit2
    Case "Celsius"
      dTempValue2 = dTempValue1InF / 33.8
    Case "Fahrenheit"
      dTempValue2 = dTempValue1InF
    Case "Kelvin"
      dTempValue2 = dTempValue1InF / -457.87
    Case "Rankine"
      dTempValue2 = dTempValue1InF / -458.67
    Case "Delisle"
      dTempValue2 = dTempValue1InF / 1.2
    Case "Newton"
      dTempValue2 = dTempValue1InF / 102.414
    Case "Réaumur"
      dTempValue2 = dTempValue1InF / 34.25
    Case "Rømer"
      dTempValue2 = dTempValue1InF / 3.42857143
  End Select
  ' Convert dTempValue2 to string
  If Abs(dTempValue2 - Int(dTempValue2)) > 0.00000001 Then
    frmTemperatureConverter.txtTempValue2.Value = Format(dTempValue2, "###0.00000000")
    frmTemperatureConverter.txtTempValue2.Value = Format(dTempValue2, "General Number")
  End If
End Sub
  1. Next go to the form and double click “Close” button. Enter codes:
Private Sub btnClose_Click()
  Unload Me
End Sub
  1. Then double click on the form to enter it. You can see 2 combo boxes on the top. Make sure you choose “UserForm” for the left and “Initialize” for the right.Choose "UserForm" for the Left Combo Box and "Initialize" for the Right
  2. And paste codes there, too.
Private Sub UserForm_Initialize()
    cmbTempUnit1.List = Array("Celsius", "Fahrenheit", "Kelvin", "Rankine", "Delisle", _
                        "Newton", "Réaumur", "Rømer")
    cmbTempUnit2.List = Array("Celsius", "Fahrenheit", "Kelvin", "Rankine", "Delisle", _
                        "Newton", "Réaumur", "Rømer")
End Sub
  1. Lastly, save all codes.

Insert a Module

  1. Still in VBA editor, click “Insert” under “Normal” project.
  2. But this time choose “Module”.Click "Normal"->Click "Insert"->Click "Module"
  3. Double click on it to open and paste codes:
