The information in this article applies to:
When HttpSendRequestEx is used, error 12019 (ERROR_INTERNET_INCORRECT_HANDLE_STATE) may be returned by InternetWriteFile.
This can be avoided by specifying INTERNET_FLAG_NO_CACHE_WRITE in the call to HttpOpenRequest. Here's an example:
HINTERNET hRequest = HttpOpenRequest(hConnect, "POST", "servername",
NULL, NULL, NULL, INTERNET_FLAG_NO_CACHE_WRITE, 0);
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
For sample demonstrating the use of HttpSendRequestEx and InternetWriteFile, please see the following article in the Microsoft Knowledge Base:
