FTP Upload in async?

[Phiru]

I am using wininet.h to download or upload file to FTP.
I opened Internet with this, InternetOpen("abc", INTERNET_OPEN_TYPE_PRECONFIG,
NULL, NULL, INTERNET_FLAG_ASYNC);
So, I made CallbackFunc which includes
INTERNET_STATUS_HANDLE_CREATE
INTERNET_STATUS_REQUEST_COMPLETE
INTERENT_STATUS_RESPONSE_RECEIVED.

And I set the callback Func in InternetSetStatusCallback.

The downloading function works properly.
However, I don't know the flag for Upload in Callback Function.

As I found, INTERNET_STATUS_REQUEST_SENT.. or something seems like what I need.

anyways, anyone have ideas??
Thanks.
