This article was previously published under Q321490 SYMPTOMS
If you use the InternetQueryDataAvailable function and the InternetCloseHandle function asynchronously in different threads, you can cause an access violation.
CAUSE
If you call InternetCloseHandle, this causes Wininet to release the handle object, which may later be accessed by InternetQueryDataAvailable on a different thread.
RESOLUTION
To avoid a possible access violation, you must call InternetCloseHandle and InternetQueryDataAvailable on the same thread.
STATUSMicrosoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
The access violation does not occur when Wininet is used synchronously.
