The two functions are used for different purposes. Getdatafromurl is used for storing the remote contents into a memory variable, Getfilefromurl is used to gather a remote file and save it as a local file. I suppose you only need the first function, but I presented both because they are closely related.

*To create memory variable
lcURL='http://hk.finance.yahoo.com/d/quotes.csv?s=0179.HK&f=sl1d1t1c1ohgv&e=.csv'
lcText=Getdatafromurl(lcUrl)

*To save a file
lcUrl='lcURL='http://hk.finance.yahoo.com/download/hkdollar.csv' 
lcSuccess=getfilefromurl(lcUrl,'C:\mylocalfile.csv')
