What is the name of the file that contains this code and what is the error you receive?

There is no operator like "::".

The '::' is not valid in a JavaScript identifier, so the parser is reading "objReader" and expects it to be followed by "(" - the beginning of a JS parameter list.

I'd expect '::' in C++ code, not JavaScript. This code is valid in neither.

Maybe there is something else in the project that should process this to produce valid JS code? In which case Visual Studio may be unaware of that processing but it may run anyway. This seems unlikely.

i think this function is written as an event of the object tag, but there is some syntactic error

If I get time I'll download and have a look at the weekend.
