Simulate a simple polling application and draw the results basing upon the votes gained by the individual candidates.Assumptions can be made wherever necessary.
(A)Program Design :
(B) Property(Controls Used) :
- One OptionButton (Name-Option1) , Index= 0 to 12 (For selecting particular candidate)
- One Label(Label1) , Index= 0 to 12 (Displays the name of the candidate)
- One Command Button Give vote
(C) Attaching Code to the Object :
Open Explicitcn For Random As New ADODB.Connection Public rs As New ADODB.Recordset Dim rs As String Dim names As String Dim i As Integer Dim Index As String |
Private Sub Command1_Click() If rs.State = 1 Then rs.Close End If rs.Open "update PollingApp set TotalVotes=TotalVotes+1 where CandidateName="" & Option1.Item(indexName).Caption & "",cn,adOpenDynamic,adLockOptimistic" If rs.State = 1 Then rs.Close End If rs.Open "select*from PollingApp", cn, adOpenDynamic, adLockOptimistic For i = 0 To Option1.Count - 1 Option1(i).Caption = "Number of Votes are" & rs("TotalVotes") rs.MoveNext End Sub |
Private Sub Form_Load() cn.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial" Catalog = Database: Data Source = "U5W4G8" cn.CursorLocation = adUseClient If rs.State = 1 Then rs.Close End If rs.Open "select*from PollingApp", cn, adOpenDynamic, adLockOptimistic For i = 0 To Option1.Count - 1 Label1(i).Caption = "Number of Votes are" & rs("TotalVotes") rs.MoveNext Next End Sub |
Private Sub Option1_Click(Index As Integer) names = Option1.Item(Index).Caption indexName = Index End Sub |
