You can use HttpQueryInfo()
with HTTP_QUERY_CONTENT_LENGTH
for this, although the server is not required to send the content length and so you should not rely on this.
How to get the file size before downloading
题
I am trying to download a binary file from a http: server. I am using the functions InternetOpenUrl()
and then InternetReadFile()
to download the file. Is it possible to know the size of the file before downloading?.
Thanks Vinod

You might want to call InternetGetLastResponseInfo
after the call to InternetOpenUrl
to get the response headers. Those should (most likely) contain the content-length
of the file.
