    Code:
    std::string GetObject(std::string Option) // No semi-colon
    {
    	std::string DirOrFileName;
    	std::cout << "Please enter "<< Option; // Blah blah blah
    	std::getline(std::cin,DirOrFileName,'\n'); // Blah blah blah
    	return DirOrFileName;
    }

    Replace ???? with std::string.
    There are 10 types of people in this world, those who cringed when reading the beginning of this sentence and those who salivated to how superior they are for understanding something as simple as binary.

    It doesn't work, I tried. I get "expected unqualified-id before '{' token"
    expected ',' or ';' before '{' token

    are you #including <string>?

    post the code and mark the line that's giving you an error.

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?

    As pointed out already, get rid of the unexpected semicolon.
    Code:
    std::string GetObject(std::string Option);
    {
    	std::string DirOrFileName;
    	std::cout<<"Please enter "<<Option;
    	getline(std::cin,DirOrFileName,'\n');
    	return DirOrFileName;
    }

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
