Hello Noel,
For memory related issues, sometimes the problem is not directly at the
line that reports an error. Maybe the pointer or some memory is in chaos
when the program goes there. The Assert workaround here is not quite
trustable, since the root cause of it is still not found. Maybe this
function just correct some pointer accidently. Could you please test the
following items?
1) In BOOL CUpgrade::CheckUpgradeAvailability(), call
CWebRequest::SaveResponse(_T("some constant string")) to test whether the
problem happens.
2) Change some code link sequence in BOOL CWebRequest::SaveResponse(LPCTSTR
pszFileName) to see if the behavior has changed some.
3) You mentioned that ASSERT(dwByteRead <= DATA_BUFFER_SIZE) is put in BOOL
CWebRequest::GetResponse(). How is this function related to SaveResponse?
4) I understand the problem happens in a big application. However, in order
to troubleshoot it, we need at least a sample to repro it. Since the
problem is quite related to CWebRequest class, is it possible for you to
build a small sample based on just this class to repro it? We will look
into it on our side. In newsgroup support, currently we don't provide
service to connect to customer's machice for remote debugging since it is
quite related to security and privacy. You may contact our product support
service if you want an support engineer to work specially with you on it.
Please feel free to post here if you want so.
Thanks very much. If there is anything unclear, please feel free to post
here.
Best regards,
Yanhong Huang
