VC7, Web Service and Proxy server

[Farooque Khan]

Hi,

I am consuing a web service in a VC7 application. I included
the web service as a 'web reference' and calling it's method. Now
I want my application to connect to the web service through a proxy
server. Is this possible? if yes, how?

I have searched but only found proxy use through C# (WebProxy class),
nothing about VC++ 7.

any help would be appreciated.

Thanks,

Are you using ATL Server (is your web reference class a derivative of
CSoapSocketClientT<>) ?
If so, then it has a method called SetProxy which takes as arguments the
name of the proxy server and the port

Thanks Bogdan,

Yes I *was* using CSoapSocketClientT derived class for the web reference.
The SetProxy() method of this works fine, but now I have to provide Proxy
Authentication also. I have now derieved my class from CSoapWininetClient
and trying to use the HINTERNET members to provide proxy authentication
information. I am not yet successfull at this. Can you suggest something? Is
my
approach correct?

Thanks,

I think CSoapWininetClient does not support proxy authentication.
A suggestion: you could derive your own class from CSoapWininetClient,
override the ConnectToServer method and copy the old code inside atlsoap.h
for CSoapWininetClient::ConnectToServer, with the modifications highlighted
below:

You will also need to declare 2 new CStringT members, m_strProxyUserName and
m_strProxyPassword, and two new methods to set the values

HRESULT ConnectToServer()
{
if (m_hConnection != NULL)
{
return S_OK;
}

m_hInternet = InternetOpen(
ATLSOAPINET_CLIENT,
m_strProxy.GetLength() ? (INTERNET_OPEN_TYPE_PRECONFIG |
INTERNET_OPEN_TYPE_PROXY) : INTERNET_OPEN_TYPE_PRECONFIG,
m_strProxy.GetLength() ? (LPCTSTR) m_strProxy : NULL,
NULL, 0);

if (m_hInternet != NULL)
{
if (m_dwTimeout != 0)
{
InternetSetOption(m_hInternet, INTERNET_OPTION_CONNECT_TIMEOUT,
&m_dwTimeout, sizeof(m_dwTimeout));
InternetSetOption(m_hInternet, INTERNET_OPTION_RECEIVE_TIMEOUT,
&m_dwTimeout, sizeof(m_dwTimeout));
InternetSetOption(m_hInternet, INTERNET_OPTION_SEND_TIMEOUT,
&m_dwTimeout, sizeof(m_dwTimeout));
InternetSetOption(m_hInternet, INTERNET_OPTION_SEND_TIMEOUT,
&m_dwTimeout, sizeof(m_dwTimeout));
//////////////////////////////////////////////////////// Add these here:
InternetSetOption(m_hInternet, INTERNET_OPTION_PROXY_USERNAME,
m_strProxyUserName.GetBuffer(), m_strProxyUserName.GetLength());
InternetSetOption(m_hInternet, INTERNET_OPTION_PROXY_PASSWORD,
m_strProxyPassword.GetBuffer(), m_strProxyPassword.GetLength());
//////////////////////////////////////////////////////// End Extra:

}
m_hConnection = InternetConnect(m_hInternet, m_url.GetHostName(),
(INTERNET_PORT) m_url.GetPortNumber(), NULL, NULL,
INTERNET_SERVICE_HTTP, INTERNET_FLAG_NO_UI, NULL);

if (m_hConnection != NULL)
{
return S_OK;
}
}
CloseAll();
return E_FAIL;
}
Hope this helps!

Bogdan, thanks,
your solution and a few other tweaks worked for me.

Apart from CSoapWininetClient, I also have to use InternetErrorDlg()
to take care of 407-401 response (after HttpSendRequest()).

It works now.
