Can't you use pure javascript for this? That will be lot better I think.
If you want to use C# for this, the TimeSpan class and it's properties will be useful.

Form events

What are the differences between the following events, and which should be used when?

Activated<br />
Load<br />
Shown<br />
Validated

Let's say that you want to perform some actions (run SQL, copy files, etc.) when a form appears, but with no user interaction. In which event handler do you place your code? Thanks.

This is the second question today about something that can easily be found in the documentation or on the web (search for "c# format binary string" and "c# copy part of array" to get the solutions as the first hit). You really should learn how to use google and MSDN Library, and save your forum posts until you need them. Smile | :)

Despite everything, the person most likely to be fooling you next is yourself.

In my application I have hooked the keyboard.Global hooked and in one function im getting a error saying..

“Attempted to read or write protected memory. This is often an indication that other memory is corrupt.”

It comes from this code statement,

return CallNextHookEx(hookID, nCode, wParam, ref lParam);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode,
IntPtr wParam, ref KBDLLHOOKSTRUCT lParam);

This cause to carshed my application. And Can U explain to overcome this issue.

Yes, you are having a buffer overflow/overrun in your unmanaged code.

Attach an unmanaged debugger and look for the error. Your structs that you pass to the unmanaged function is probably incorrect/too small/misaligned etc. I cant help you on that.
