Need Help with PIN Dialog Screen

Hi,

Can someone tell me why the screen would freeze when clicking the “Cancel” button on the PIN Entry Dialog screen with the function below? I have another PIN screen that works, however, I do not see anything that would cause this problem. After entering in numbers in the PIN Entry and click the “Confirm” button, the screen exits fine. However, I cannot cancel at all. I’m running firmware 3.1. I’m going crazy here.

Function contentPinEntry(videoRating as string) as boolean
    requestPIN = checkContentRating(videoRating)
    isPasscodeCorrect = CreateObject("roBoolean")
    isPasscodeCorrect.SetBoolean(false)
   
    if requestPIN = true then
        port = CreateObject("roMessagePort")
        pinScreenConfirm = CreateObject("roPinEntryDialog")   
        pinScreenConfirm.setMessagePort(port)
        
        pinScreenConfirm.AddButton(1, "Confirm")
        pinScreenConfirm.AddButton(2, "Cancel")
        pinScreenConfirm.SetNumPinEntryFields(4)
        pinScreenConfirm.SetTitle("Enter Content Passcode")
        pinScreenConfirm.EnableBackButton(true)
        
        pinScreenConfirm.Show()
        
        while(true)
            msg = wait(0, port)
            
            if type(msg) = "roPinEntryDialogEvent" then
                if msg.isButtonPressed() then
                    if msg.GetIndex() = 1 then
                        pinEntered = pinScreenConfirm.Pin()
                        
                        if Len(pinEntered) = 4 then
                            if RegRead("contentProtectionPIN") <> invalid then
                                if pinEntered = RegRead("contentProtectionPIN")
                                    isPasscodeCorrect.SetBoolean(true)
                                    exit while
                                else
                                    pinScreenConfirm.SetTitle("Incorrect!  Please try again.")
                                end if
                            end if
                        else
                            pinScreenConfirm.SetTitle("Passcode must be four digits in length")
                        end if
                    else if msg.GetIndex() = 2 then
                        pinScreenConfirm.Close()
                        exit while
                    else
                        pinScreenConfirm.Close()
                        exit while
                    end if
                else if(msg.isScreenClosed()) then
                    exit while
                end if 
            end if
        end while
    else
        return true
    end if
    
    if isPasscodeCorrect.GetBoolean() = true then
        return true
    else
        return false
    end if
End Function

Are you getting the isButtonPressed event? Have you tried moving the AddButton calls to after the EnableBackButton call? Some screens can be particularly (and unpredictably) sensitive to the order in which their setup methods are called.

Hi TheEndless,

Thanks for the reply. It was actually something outside of the function. I wasn’t closing a background canvas when I should have. Of course, late night programming can do that to you.

Thanks,
