accessing membership DB from windows (not ASP) app

D

David Thielen

Hi;

When we create the membership DB we have to create the admin user in it in
our setup program. Otherwise, there is no way for an admin to get in our
ASP.NET app and create additional users.

What we have works unless the user first selects the wrong database for
which database is the membership database (this step occurs when they created
the database and then cancel or an error occurs before the admin member is
added).

I think what is happening is that the SqlRoleProvider is not re-reading the
setup app's config file. We update the file as follows before create the
SqlRoleProvider object.

VendorInfo info = new SqlServerInfo();
Configuration config =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ConnectionStringsSection cs =
(ConnectionStringsSection)config.GetSection("connectionStrings");
cs.ConnectionStrings.Remove("MembershipSqlServer");
config.Save();
ConfigurationManager.RefreshSection("connectionStrings");
// ConnectionStringSettingsCollection csc =
ConfigurationManager.ConnectionStrings;

cs.ConnectionStrings.Add(new
ConnectionStringSettings("MembershipSqlServer", connStr, info.ClassName));
config.Save();
ConfigurationManager.RefreshSection("connectionStrings");
ConnectionStringSettingsCollection csc =
ConfigurationManager.ConnectionStrings;
object obj = csc["MembershipSqlServer"];
cs = (ConnectionStringsSection)config.GetSection("connectionStrings");
csc = cs.ConnectionStrings;
obj = csc["MembershipSqlServer"];

obj is the correct connection string the second time (the first time it's
wrong as I entered it wrong to test this).

The error I get is when I call the roleProvider object to check IsInRole it
tells me it cannot find the stored procedure it uses.

Any ideas how to work around this?

Hello Dave,

The connection string property of RoleProvider class is set in its
Initialize() method. And In Initialize() method, it will call
ConfigurationManager's ConnectionStrings to get the actual string. So after
you change the ConnectionStrings in your previous code, you may call
ConfigurationManager's RefreshSection method to refresh the named section
so the next time it is retrieved it will be re-read from disk.

Sincerely,

Luke Zhang

Hello Dave,

Do you mean create a singleton RoleProvider? It will still load the
original value of connection string and didn't use the updated one. I think
you may consider create your customized RoleProvider and override the
Initialize() method. For example. like this:

Hello Dave,

Can you let us know how you implement the customized roleprovider? In fact,
in roleprovider's Initialize method, we can set how it load the connection
string:

public override void Initialize(string name, NameValueCollection config)
{

....
pConnectionStringSettings =
ConfigurationManager.ConnectionStrings[config["connectionStringName"]];

if (pConnectionStringSettings == null ||
pConnectionStringSettings.ConnectionString.Trim() == "")
{
throw new ProviderException("Connection string cannot be blank.");
}

connectionString = pConnectionStringSettings.ConnectionString;
}


From http://msdn2.microsoft.com/en-us/library/317sza4k.aspx

We may change code here to set the connection we want.

Luke Zhang

Is the source to SqlRoleProvider available? The problem appears to be in:

internal static RuntimeConfig GetAppConfig()
{
if (!HttpConfigurationSystem.UseHttpConfigurationSystem)
{
return RuntimeConfig.GetClientRuntimeConfig();
}
return CachedPathData.GetApplicationPathData().RuntimeConfig;
}

After the first request it gets the cached config. How can I have it re-read
it?

hello,

The source of SqlRoleProvider is not shared, but we can get some idea from
Reflector:

http://www.aisto.com/roeder/dotnet/

Also, I think you may create the customized RoleProvider by inheirting from
SqlRoleProvider and override its Initialize() method

Let me add to that. RefreshSection does not cause it to re-read the entry.
Here is my code:

public static void SetAppExeConfig(string connStr)
{

VendorInfo info = new SqlServerInfo();
Configuration config =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ConnectionStringsSection cs = config.ConnectionStrings;
cs.ConnectionStrings.Remove("MembershipSqlServer");
cs.ConnectionStrings.Add(new
ConnectionStringSettings("MembershipSqlServer", connStr, info.ClassName));
config.Save();
ConfigurationManager.RefreshSection("connectionStrings");
}

At the end of that if the above is called twice, the first time with the
wrong connection string, it continues to use the first string.

Not sure about your specific scenario - but this works for me:

namespace ConfigTest
{
class Program
{
static void Main(string[] args)
{
UpdateAppSettings();

Console.WriteLine("1");
for (int i = 0; i < ConfigurationManager.AppSettings.Count; i++)
{
Console.WriteLine(ConfigurationManager.AppSettings);
}

UpdateAppSettings();

Console.WriteLine("2");
for (int i = 0; i < ConfigurationManager.AppSettings.Count; i++)
{
Console.WriteLine(ConfigurationManager.AppSettings);
}
}

static void UpdateAppSettings()
{
// Get the configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);

// Add an entry to appSettings.
int appStgCnt =
ConfigurationManager.AppSettings.Count;
string newKey = "NewKey" + appStgCnt.ToString();

string newValue = DateTime.Now.ToLongDateString() + " " +
DateTime.Now.ToLongTimeString();

config.AppSettings.Settings.Add(newKey, newValue);

// Save the configuration file.
config.Save(ConfigurationSaveMode.Modified);

// Force a reload of the changed section.
ConfigurationManager.RefreshSection("appSettings");

}
}
}


i guess you have to re-create the provider after you changed the connection
string...

Hi;

That works for me too. And if I re-read the connection strings - I get the
new ones. The problem is that SqlRoleManager does not re-read the connection
string. From looking at the code through Reflector (what a great program) it
looks like it has it's own cache of the connection string and once read, it
will never re-read it.

That's how I got the above code - from the reflector. It looks
like RuntimeConfig.GetAppConfig() reads the config file the first
time and then always uses a cached config after that.

Is there anyway to tell it to re-read that cached internal config?
