WebService Authenticate against proxy server.

When proxy server configured for PC or in a network , if it require authentication to make certain request then you have to use following code.

Error: (407) Proxy Authentication Required.

Here i am taking example of SharePoint List service. I added reference of SharePoint List Service.


ListSerivce lst = new ListSerivce();
//Get Default Proxy Setting
IWebProxy proxy = System.Net.WebRequest.DefaultWebProxy;
// Authenticate using network credential. In My case i need authentication using windows account.
proxy.Credential = new System.Net.NetworkCredential(“username”,”password”,”domain”);
lst.Proxy = proxy;
// Make Call to WebService Method.

You can even find System.Net.WebProxy.GetDefaultProxy() return default proxy setting but it is deprecated to better to use WebRequest.DefaultWebProxy.

You can even configure your own webproxy

Lists lst = new Lists();
System.Net.WebProxy proxy = new WebProxy();
proxy.Address = new Uri("http://proxy:8090");
proxy.Credentials = new NetworkCredential ("username", "password", "domain");
lst.Proxy = proxy;

In both case credential pass as NetworkCredential but you can use CredentialCache to pass other type of credential.

Please give comment on this. Also if you have any better idea please free give your suggestion.

Run MSI In Context Of User

Several times to install program you need administrative or other user privileges. For example you take input from user for username and password and run that program in that particular user context.

I faced problem during installing MSI in particular user context or start IIS in context of another user.

I found this solution using command line argument.

1. Inermgr ( Run following command in Command line)

C:\runas /user:administrator “mmc %sysroot%\system32\inetsrv\iis.msc”
Enter the password for administrator :

2. MSI install
C:\runas /user:administrator “msiexec /i <full path of msi file>”

c:\runas /user:administrator “msiexec /i c:\download\setup.msi”
Enter the password for administrator :

For more information just type runas /? on command line.

Unauthorized (401.1) Exception calling Web Services in SharePoint (.Net Framework 3.5 )

After installing .NET Framework 3.5 sp1 following error may occur while making call to webservice. This thing mostly happen when you are trying to make webservice call using fully qualified domain name instead of IPAddress or Hostheader is used to map request on single port.

I found one strange thing in IIS Log that , for such request it is not sending authentication information to webservice request even though you pass it in NetworkCredential. One solution is to disable integrated authentication and use basic authentication. This will compromise with security but solve problem. Another solution that need to require registry changes. You can find it at following link with grate explanation.

SPAlert DynamicRecipient On Custom List

In SharePoint default. alert functionality available. You can subscribe Alert on List or ListItem using AlertMe action. But in certain situation you need to automize this alert. Like Alert automatically send to particular user even though he/she did not subscribe event.

There are two way to do . Create feature that receive ItemAdded or ItemUpdated Event , Find out user and email address , send email using SendEmail Functionality of SharePoint.

Another way is use DynamicRecipient property of SPAlert.

Sample List :

Here you can see that To Field is type of Person or Group. Send automatic email to user enter ‘To’ Field.

List Entry look Like (Edit View).

Note : UserName must have email id associated with him.SMTP also configured properly for site.

Now run following code against your site. (use console application).

SPSite site = new SPSite("http://yoursite");
SPWeb web = site.OpenWeb();
SPList lst = web.Lists["Alert Test"];
SPAlert alert = web.Alerts.Add();
alert.AlertFrequency = SPAlertFrequency.Immediate;
alert.AlertType = SPAlertType.List;
alert.EventType = SPEventType.All;
alert.DynamicRecipient = "To";
alert.List = lst;
alert.Status = SPAlertStatus.On;
alert.Title = “Auto Email Alert”;
alert.Filter = "<Query><IsNotNull><FieldRef Name='To'></FieldRef></IsNotNull></Query>";            
alert.Update();

You can even use FeatureReceiver to install/ Activate / deactivate this thing as a feature.
