IDownloadManager crash with text file   

My app implements IDownloadManager, which seems to work fine for most
files. However, when I handle a url that downloads a text file
attachment, my app will crash with an exception thrown from
ieframe.dll.  This seems to happen only if I return S_OK from
IDownloadManager::Download().  If I return E_FAIL, I get the default
download dialog from IE and everything works.

Has anyone seen this or know of a fix? Basically I have my own
download dialog that I want to handle this download, so I am returning
S_OK to "fake" IE into thinking the download has be taken care of.

Thanks!

Hi,

I have come across this issue with file attachments, but without
seeing your implementation of the ::Download method, I can only tell
you that the crash in my case was related to
RegisterBindStatusCallback call which was returnning E_FAIL while I
was returnning S_OK from ::Download method.

MH

Yes I think this is my issue as well. Did you find a resolution for
this problem?

Re: IDownloadManager crash with text file   

Hi,

You can find the solution by downloading a freeware package from
http://code.google.com/p/csexwb2/downloads/list,
csExWBv2.0_Includes_ComUtilities.zip. Within the package, locate
ComUtilities solution which is a COM component. Open up UtilMan.cpp,
the methods that you need to look at are CUtilMan class ::Download,
and WBBSCBFileDL class (IBindStatusCallback
implementation) ::OnStartBinding and ::OnStopBinding methods.

MH
