Summary: Upload file hangs

Initial Comment:
Trying to upload a file. I read the online documentation and multiple forums. None proved any success.

Nothing special:
- 12kb text file
- Connects, content length matches file size. Then it hangs.

CURLOPT_URL -> my local IIS5 server
CURLOPT_INFILESIZE -> size of file
CURLOPT_INFILE -> FILE* opened file
CURLOPT_UPLOAD -> 1
CURLOPT_VERBOSE -> 1

curl_easy_perform( ) // HANGS HERE - never get past this line

Tried on Win7 and Win2k3

Any advice or suggestions? Thanks.

File needs to be opened in BINARY mode. Did not know this.

Works for me now.

More info:
Tried another method using READFUNCTION (sample that came with libcurl)
and READDATA (the FILE*) and it prints out
- Read 4 bytes from file
- Read 0 bytes from file
<hangs here>

Message:
Stepped through the code this morning (mine and LibCurl) and the function
Transfer( ) function in transfer.c continually loops in the while loop.
This is the cause of the hang. But I don't know why.
