I'm using VC++ to write an VC++ unmanaged client to communicate to a C#.NET
web service. I have the proxy class for the unmanaged client and it uses the
default CSoapSocketClientT<> template as it's HTTP connection. This works
fine until I start using a proxy server with authorization rather than a
direct HTTP connection. I keep getting a 407 un-authorized response. I've
have looked at both the CNTLMAuthObject and CBasicAuthObject objects in
combination with the NegotiateAuth method but have had no luck.
I have older VC++ clients that use the CInternetSession class and I'm able
to set the proxy server authorization using the:
pTSConnection->SetOption(INTERNET_OPTION_PROXY_USERNAME,strLogin Name,
lstrlen (strLoginName)) ;
pTSConnection->SetOption(INTERNET_OPTION_PROXY_PASSWORD,strLogin Password,
lstrlen (strLoginPassword)) ;
What I what is the CSoapSocketClientT<> equivalent of the
CInternetSession.SetOption(INTERNET_OPTION_PROXY_U SERNAME) and
CInternetSession.SetOption(INTERNET_OPTION_PROXY_P ASSWORD).
Best Regards,
Dave 4 5922
Yes, I would certainly consider changing the template class just to see if
it works (i.e. eliminate the fact that the proxy is incorrectly configured
or auth details are incorrect). That being said, my experience is
thatCSoapMSXMLInetClient is not as fast as others as it has to do a lot of
COM. In practice though this is not a major time consumer in the app as a
whole.

Also tried:
vProxyServer.vt=VT_BSTR ;
vProxyServer.bstrVal=SysAllocString(L"192.168.1.2: 808") ;
This doesn't cause the setProxy to crap out but the proxy redirection is
ignored...

news:%2****************@tk2msftngp13.phx.gbl... Igor, Using CSoapMSXMLInetClient looks like it might work and I have a VB example working using MSXML4 library directly. However it seems to crap
out in VC++. The problem seems to be in passing in the name of the proxy
server. I'm using VARIANTS but do not seem to have any luck. Documentation for
VC++ is non existent!!! Anyone got MSXML4 working in VC++ with proxy support?

Dave, vProxyServer.vt=VT_BSTR ; vProxyServer.bstrVal=SysAllocString(L"192.168.1.2: 808") ; This doesn't cause the setProxy to crap out
When you say "crap out", what do you mean, exactly?
vProxyServer.vt=VT_ARRAY|VT_BSTR;
I think this should be a SAFEARRAY of VARIANT, since clients are generally
scripting languages, who can only produce this kind of SAFEARRAY.
I'm not familiar with ServerXMLHTTPRequest - does the docs say it takes an
array? vByPassList.vt=VT_ERROR ; vByPassList.bstrVal=(BSTR)DISP_E_PARAMNOTFOUND ;
That doesn't look right... Try:
vByPassList.vt = VT_ERROR;
vByPassList.scode = DISP_E_PARAMNOTFOUND;
Please ping back with more details,
Kim
Thanks for looking at this Kim,
All the documentation says:
varProxyServer [in, optional]
The name of a proxy server or a list of proxy server names. http://msdn.microsoft.com/library/de...th_sz_65q1.asp
When I say craps out it causes an UnknownException.
Best Regards,
Dave
