I get a syntax error near dtTo. Not sure if dates are handled differently or if it is something else. The select statement is hitting the Case False. Code below...

 Dim con As New SqlConnection
        Dim cmd As New SqlCommand

        Try
            con.ConnectionString = sqlComm
            con.Open()
            cmd.Connection = con
            Select Case ysnNew
                Case False
                    cmd.CommandText = "Update tblLeads " & vbCrLf &
                       "SET strType  = @strType," & vbCrLf &
                            "numClient  = @numClient," & vbCrLf &
                            "strLast = @strLast," & vbCrLf &
                            "strFirst = @strFirst" & vbCrLf &
                            "dtTo = @dtTo, SqlDbTypes.DateTime" & vbCrLf &
                            "tmTo = @tmTo, sqldbtypes.Time" & vbCrLf &
                            "dtCTC = @dtCT, SqlDbTypes.DateTime" & vbCrLf &
                            "tmCTC = @tmCT, sqldbtypes.Time " & vbCrLf &
                            "strNotes = @strNotes" & vbCrLf &
                            "strResponse = @strResponse" & vbCrLf &
                            "strLeadType = @strLeadType" & vbCrLf &
                            "ysnBad = @ysnBad" & vbCrLf &
                            "ysnPhone = @ysnPhone" & vbCrLf &
                       "Where numLeadID = @numLeadID"
                Case Else
                    cmd.CommandText = "Insert Into tblLeads " & vbCrLf &
                            "strType  = @strType," & vbCrLf &
                            "numClient  = @numClient," & vbCrLf &
                            "strLast = @strLast," & vbCrLf &
                            "strFirst = @strFirst" & vbCrLf &
                            "dtTo = @dtTo, SqlDbTypes.DateTime" & vbCrLf &
                            "tmTo = @tmTo, sqldbtypes.Time" & vbCrLf &
                            "dtCTC = @dtCT, SqlDbTypes.DateTime" & vbCrLf &
                            "tmCTC = @tmCT, sqldbtypes.Time " & vbCrLf &
                            "strNotes = @strNotes" & vbCrLf &
                            "strResponse = @strResponse" & vbCrLf &
                            "strLeadType = @strLeadType" & vbCrLf &
                            "ysnBad = @ysnBad" & vbCrLf &
                            "ysnPhone = @ysnPhone" & vbCrLf & ""
            End Select
            cmd.Parameters.AddWithValue("@strType", Me.txtType.Text)
            cmd.Parameters.AddWithValue("@numClient", Me.txtClient.Text)
            cmd.Parameters.AddWithValue("@strLast", Me.txtlast.Text)
            cmd.Parameters.AddWithValue("@strFirst", Me.txtFirst.Text)
            cmd.Parameters.AddWithValue("@dtTo", Me.dtTO.Text)
            cmd.Parameters.AddWithValue("@tmTO", Me.tmTO.Text)
            cmd.Parameters.AddWithValue("@dtCT", Me.dtCT.Text)
            cmd.Parameters.AddWithValue("@tmCT", Me.dtCT.Text)
            cmd.Parameters.AddWithValue("@strNotes", Me.txtNotes.Text)
            cmd.Parameters.AddWithValue("@strResponse", Me.txtEmail.Text)
            cmd.Parameters.AddWithValue("@strLeadType", Me.cboVehicle.Text)
            cmd.Parameters.AddWithValue("@ysnBad", Me.chkBad.Text)
            cmd.Parameters.AddWithValue("@ysnPhone", Me.ysnPhone.Text)
            Select Case ysnNew
                Case False
                    cmd.Parameters.AddWithValue("@numLeadID", Me.txtID.Text)
            End Select
            cmd.ExecuteNonQuery()

        Catch ex As Exception
            MessageBox.Show("Error while inserting record on table..." & ex.Message, "Insert Records")
        Finally
            con.Close()
        End Try

one thing for sure, you are missing a comma on this line:

"strFirst = @strFirst," & vbCrLf &

also, it is the fist time I see this syntax:

"dtTo = @dtTo, SqlDbTypes.DateTime" & vbCrLf &

Open in new window


I would be very surprised if you can specify a datatype like this! and I don't see any trace of if in the sql-bible: https://msdn.microsoft.com/en-us/library/ms177523.aspx

Took SqlDbTypes.DateTime out of all places I referenced it. Fixed the comma issues and now getting: Error while inserting record... Conversion failed when converting date and/or time from character string.

your date & time fields are surely incorrectly formatted. Can you try something like this (for all your date & time fields):
cmd.Parameters.AddWithValue("@dtTo", Me.dtTO.Value)

Open in new window


Here I suppose that dtTO is a datetimepicker control.

My time fields tmTO and tmCT don't like that. It says value is not a member of a textbox. I use a textbox for the user to enter the times (ie. 3:15 PM) because I have to measure how long it took for a task to be completed. Should I be doing it differently?

and what is the datatype in the database?

You will need to convert your text to a datetime value probably

I never tried those. There is no real .Net equivalent. You could at least try to convert from text to datetime:
Dim dtmTime As DateTime = DateTime.Parse(tmTO.Text)
cmd.Parameters.AddWithValue("@tmTO", dtmTime)

That worked. Just have one question. Is there a way to format date and time to read month/day/year instead of the other way around?

In the sql table the date is formatted 2016-05-09. Does that have to be the format or can it be 05-09-2016?

it is usually not the job of SQL server to format dates.

but if you really need, you can use Format:
SELECT FORMAT(GETDATE(), 'MM-dd-yyyy')
