    unterminated[] while parsing string

    Code:
    HOVResponse = Replace(HOVResponse, "[", string.empty)
    i am sure this is a simple problem to solve but it has me stumped, i understand [ is a special regex character but how do i get around this and replace [ from a string as it is throwing the exception in the title

    Re: unterminated[] while parsing string

    Apologies if I'm missing something more complex about your needs. I don't have access to VB.Net at the moment to test this, but I would think something like the following would work, presuming that you want to simply strip out all "[" characters from a string:

    Code:
    HOVResponse = HOVResponse.Replace("[", "")

    "" and String.Empty are really the same thing, so either should work. But I would use the HOVResponse.Replace. Not sure why Replace would give you an error like that, RegEx doesn't have anything to do with it as far as I know. Unless it's doing something with it on the backend, or if it's a custom Replace function. To answer your question directly though, if you are using RegEx to do a replace, and want to use a RegEx character, you need to escape it ... I think with the \

    Code:
    HOVResponse = Replace(HOVResponse, "\[", string.empty)
    But that doesn't feel right either.

    it worked fine as soon as i added "\" before the special regex char

    As far as I can tell, if we're in a VBA context, Replace() is a built-in function and may use regex by default? I don't think OP understood your point that in general, VB .NET developers don't use and have no clue what a built-in function does.
    This answer is wrong. You should be using TableAdapter and Dictionaries instead.
