I tried this:

code:

---

function test() {
    var MAX_PATH = 260;
    var url = "C:\Documents and Settings\Vincy\Desktop\headers.txt";
    var han = "C:\WINDOWS\notepad.exe";
    var result = Interop.Allocate((MAX_PATH+1)*2);

    Interop.Call('shell32.dll', 'EstimateFileRiskLevel', url, ".txt", han, result);
    var result = result.ReadString(0, false);
    return result;
}

---

But debug says something like:
CallDll failed collocation of function "EstimateFileRiskLevel"...

What should i do? How should i read the result?
Thanks
