i have four combo boxes in my form, each combo box has 2 or 3 selections
i need to check each combo box for a selection, if nothing is selected i need to have a error message come up in a message box
each selection in the combobox is woth different points so i am using a counter and when the user click the button it shows the total points in a message box
here is my code
Private Sub btnAssessment_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAssessment.Click
Dim intPtsCnt As Integer
If cmbAge.SelectedIndex = -1 Then
MessageBox.Show("Please Select Your Age", "Error")
cmbAge.Focus()
Else
If cmbAge.SelectedIndex = 0 Then
intPtsCnt = intPtsCnt + 1
ElseIf cmbAge.SelectedIndex = 1 Then
intPtsCnt = intPtsCnt + 2
ElseIf cmbAge.SelectedIndex = 2 Then
intPtsCnt = intPtsCnt + 3
End If
End If
If cmbSmoke.SelectedIndex = -1 Then
MessageBox.Show("Please Select", "Error")
cmbSmoke.Focus()
Else
If cmbSmoke.SelectedIndex = 0 Then
intPtsCnt = intPtsCnt + 4
ElseIf cmbSmoke.SelectedIndex = 1 Then
End If
End If
If cmbBP.SelectedIndex = -1 Then
MessageBox.Show("Please Select", "Error")
cmbBP.Focus()
Else
If cmbBP.SelectedIndex = 0 Then
intPtsCnt = intPtsCnt + 2
ElseIf cmbBP.SelectedIndex = 1 Then
End If
End If
If cmbDiet.SelectedIndex = -1 Then
MessageBox.Show("Please Select", "Error")
cmbDiet.Focus()
Else
If cmbDiet.SelectedIndex = 0 Then
intPtsCnt = intPtsCnt + 1
ElseIf cmbDiet.SelectedIndex = 1 Then
End If
End If
MessageBox.Show(Convert.ToString(intPtsCnt), "Total")
End Sub
when i run the program and click the button all 4 error message boxes show up then it shows the total points, i want it to go through each combo box one at a time
