Open the frmTeller form in the code editor and locate the btnGetBalance click event code. 2. Inside the event procedure, prior to the Try block, declare and instantiate a variable of type CheckingAccount called oCheckingAccount, a variable of type SavingsAccount called oSavingsAccount, and a variable of type Account called oAccount: Dim oCheckingAccount As CheckingAccount = New CheckingAccount() Dim oSavingsAccount As SavingsAccount = New SavingsAccount() Dim oAccount As Account = New Account() 3. Depending on which radio button is selected, call the GetBalance method of the appropriate object and pass the account number value from the Account Number text box. Show the return value in the Balance text box. Place the following code in the Try block prior to the Catch statement: If rdbChecking.Checked Then txtBalance.Text = oCheckingAccount.GetBalance _ (CInt(txtAccountNumber.Text)).ToString ElseIf rdbSavings.Checked Then txtBalance.Text = oSavingsAccount.GetBalance _ (CInt(txtAccountNumber.Text)).ToString ElseIf rdbGeneral.Checked Then txtBalance.Text = oAccount.GetBalance _ (CInt(txtAccountNumber.Text)).ToString End If 4. Select Build Build Solution. Make sure there are no build errors in the Error List window. If there are, fix them, and then rebuild. 5. Select Debug Start to run the project. Enter an account number of 1 and click the Get Balance button for the Checking Account type. You should get a balance of 1,000. Test the other account types. You should get the same result, since all classes are using the same GetBalance function defined in the base class. 6. After testing, close the form, which will stop the debugger. pdf to epub c#: Best C# API to create PDF - Stack Overflow how to retrieve pdf file from database in c# Creating Windows Forms App with C#

At this point, the GetBalance method of the base class is public, which means that it can be accessed by client code of the derived classes. You will alter this so that the GetBalance method can be accessed only by the code of the derived classes and not by clients of the derived classes. To alter the GetBalance method, follow these steps: 1. Locate the GetBalance method of the Account class. 2. Change the access modifier of the GetBalance method from Public to Protected. 3. Switch to the frmTeller code editor and locate the btnGetBalance click event code. 4. Hover the cursor over the call to the GetBalance method of the oCheckingAccount object. You will see a warning stating that it is a protected function and not accessible in this context. 5. Comment out the code between the Try and the Catch statements. 6. Switch to the Account.vb code editor. 7. Add code to create the following private instance variable to the SavingsAccount class definition file: Private _dblBalance As Double 8. Add the following Withdraw method to the SavingsAccount class. This function calls the protected method of the Account base class: Public Function Withdraw(ByVal AccountNumber As Integer, _ ByVal Amount As Double) As Double _dblBalance = GetBalance(AccountNumber) If _dblBalance >= Amount Then _dblBalance -= Amount Return _dblBalance Else Throw New Exception("Not enough funds.") End If End Function 9. Select Build Build Solution. Make sure there are no build errors in the Error List window.
