will be helpful for those in need 00DB9780 is represented as hexadecimal. To declare as an int prefix the value with 0x:
code :
public static int TimerBase = 0x00DB9780;
                          //  ^^ add 0x to start of hex numbers  
public static int TimerBase = 0D;  // LHS is int, RHS is double

Variable does not exist in current context although it does exist

hope this fix your issue This will happen if you are debugging a version compiled in release mode / with the 'Optimise Code' flag set.
This is because the compiler is then free to take variables out of scope if it knows they can never be used, where as Debug mode will retain variables in scope as long as they are in-scope from a language perspective.
code :
[TestMethod]
public void Test1()
{
    GetData();
    GetData();
}

ASP.net & C# - The Control does not exist in the current context, designer.cs doesn't exist

help you fix your problem So, I found out what caused the problem. Because the drop-down boxes in question were in a template of a form (specifically under the Insert template of the FormView), the script in question was not able to "see" the drop-down lists in question. When I re-created the insert form outside of the form-view, it was able to "see" the necessary controls. The issue lay not with the C# code, but with the structure of the site's front-end.

HttpCookie authCookie = HttpContext.Request.Cookies[cookieName];

it helps some times Turns out that I don't need Context to access NotificationService. I think it's because I'm in the context already.
