HttpSendRequest : Error 997

[Craig V]

Hello, I am getting an error 997 after I make a call to HttpSendRequest. Can anyone explain why? Here is the part of the code

hInet1 = InternetOpen( m_Agent, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, INTERNET_FLAG_ASYNC )

if(!hInet1

// Error clean u
return 1

hInet2 = InternetConnect(hInet1, m_SrverName, INTERNET_DEFAULT_HTTP_PORT,
m_username, m_password
INTERNET_SERVICE_HTTP, 0, 0t)

if(!hInet2

// Error cleanu
InternetCloseHandle(hInet1)
return 1


hInet3= HttpOpenRequest(hInet2, "GET", m_instruction, HTTP_VERSION, NULL, NULL,
INTERNET_FLAG_PRAGMA_NOCACHE, 0)

if(!hInet3

// Error cleanu
InternetCloseHandle(hInet2)
InternetCloseHandle(hInet1)
return 1


if(!HttpSendRequest(hInet3, NULL, 0, 0, 0)

CHAR szBuf[80]
DWORD dw = GetLastError()

sprintf(szBuf, "%s failed: GetlastErrorReturned %u\n\n", "HttpSendRequest", dw)

els


HttpQueryInfo(inet2, HTTP_QUERY_STATUS_TEXT, data, &len_data, 0)


InternetCloseHandle(hInet1)
InternetCloseHandle(hInet2)
InternetCloseHandle(hInet3)

You used INTERNET_FLAG_ASYNC. This means that you want to use asynchronous
calls. Any call that cannot complete immediately returns immediately with
ERROR_IO_PENDING (997).

More information on using WinInet function asynchronously is here:
