File handler

Hullo,

When using the OpenUrl function in MFC it returns a file handler as follows

Returns a file handle for FTP, GOPHER, HTTP, and FILE-type Internet services only. Returns NULL if parsing was unsuccessful.

The pointer that OpenURL returns depends on pszURL’s type of service. The table below illustrates the possible pointers OpenURL can return.

URL type Returns
file:// CStdioFile*
http:// CHttpFile*
gopher:// CGopherFile*
ftp:// CInternetFile*

When I have this I want to read the file into an array.
Any ideas on how i might do this?
the handler in this case will be CHttpFile as it is a file I am reading from a http site.

thanks

Can't you just read the bytes via member function "Read()" ?

Simply asign returned pointer to CFile* and use it's member functions.
