file name as a string

[axon]

hey guys, is there a way to send a file name as a string? I get an error if I leave out the quotes around fileName, and the opening failes if they are there...any suggestions? assume that the file that user input exists in the directory ofcourse...

void generateText(string fileName, int window, int length, char* text)
{
	ifstream inStream;

	inStream.open(fileName); // the problem is here...I assume
	if ( inStream.fail() ) 
	{
		cout << "Input file opening for " << fileName << " failed.  Exiting...\n\n";
		exit(-1);
	}
}

thanks, axon
