turn OFF screen saver programmatically

Question

[DllImport("User32.dll")]
public static extern int SendMessage
    (IntPtr hWnd,
    uint Msg,
    uint wParam,
    uint lParam);

public const uint WM_SYSCOMMAND = 0x112;
public const uint SC_SCREENSAVE = 0xF140;

public enum SpecialHandles
{
    HWND_DESKTOP = 0x0,
    HWND_BROADCAST = 0xFFFF
}

public static void TurnOnScreenSaver()
{
    SendMessage(
        new IntPtr((int)SpecialHandles.HWND_BROADCAST),
        WM_SYSCOMMAND,
        SC_SCREENSAVE,
        0);
}

this code works fine. i found it from this forum.

i need another method like TurnOnScreenSaver() that stops the screen 
saver. That is i wanna turn on the screen saver first (already done) 
then on a specific condition i wanna turn off the screen saver and 
continue the process(on and off)

Answer 2

Sam is right.

change your code too

1. if (chineseGrade=="A")

2. use double chineseGPA or chineseGPA = Convert.ToDecimal(4.0);

Answer 3

chineseGrade is a string variable but you are using it as if it is a method. The compiler is not psychic and neither are we. What is it that you need to do? As best as I understand your question, you are calculating a GPA for Chinese differently than for other people but as far as I know the Chinese are the same as everyone else. So perhaps the answer is that you can just use the same calculation for Chinese people as everyone else.
