Question:1 You are creating a Windows Forms application. You add an ErrorProvider component named erpErrors and a DateTimePicker control named dtpStartDate to the application. The application also contains other controls. You need to configure the application to display an error notification icon next to dtpStartDate when the user enters a date that is greater than today's date. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. For the Validating event of dtpStartDate, create an event handler named VerifyStartDate. B. For the Validated event of dtpStartDate, create an event handler named VerifyStartDate. C. In the Properties Window for dtpStartDate, set the value of Error on erpErrors to Date out of range. D. In VerifyStartDate, call erpErrors->SetError(dtpStartDate, "Date out of range") if the value of E. dtpStartDate->Value is greater than today's date. F. In VerifyStartDate, call erpErrors->SetError(dtpStartDate, "") if the value of dtpStartDate->Value is greater than today's date. Answer: A, E Question:2 You are creating a custom control that displays an image in the background. You notice that when the control is resized, the background image flickers while the control is repeatedly repainted. You nee to eliminate the background image flicker. Which three code segments should you use? (Each correct answer presents part of the solution. Choose three.)
