wininet

[cmci]

I'm using the wininet api. I open a request and it works but when I try to
add request header it returns 0. Here's the code. Any Ideas, why
OpenRequest works, but AddRequestheaders doesn't. header is the string with
all the headers I need to add.


hRequest = HttpOpenRequest(hInternetConnect, "POST", "", _
"HTTP/1.1", vbNullString, 0, _
INTERNET_FLAG_NO_CACHE_WRITE, 0)
ret = HttpAddRequestHeaders(hRequest, header, Len(header), _
HTTP_ADDREQ_FLAG_ADD)


Any help would be greatly appreciated.

Hi - I'm having exactly the same problem ie HttpAddRequestHeaders returns 0.
Did you ever find the answer?

whenever an API function returns "something bad", you should call GetLastError and pass the result for FormatMessage API to get a human-readable explanation of the cause of the error.
