SharePoint2003>Areas menu refresh on runtime user Roles change

H

Hi All

Good Morning


I am using our custom area menu in my project.

I am changing the role(site group) of current user runtime according to which
the dynamic menu, I have created,displays the Areas according to the role
type assigned
to current user.

To change the role of current user runtime I use /_vti_bin/UserGroup.asmx
sharepoint webservice
by impersonating the adminstrator.

To impersonate I use this function:

//start coding
protected static WindowsIdentity CreateIdentity(string User, string Domain,
string Password)
{
// The Windows NT user token.
IntPtr tokenHandle = new IntPtr(0);

const int LOGON32_PROVIDER_DEFAULT = 0;
const int LOGON32_LOGON_NETWORK = 3;

tokenHandle = IntPtr.Zero;

// Call LogonUser to obtain a handle to an access token.
bool returnValue = LogonUser(User, Domain, Password,
LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT,
ref tokenHandle);
if (false == returnValue)
{
int ret = Marshal.GetLastWin32Error();
throw new Exception("LogonUser failed with error code: " + ret);
}

System.Diagnostics.Debug.WriteLine("Created user token: " + tokenHandle);

//The WindowsIdentity class makes a new copy of the token.
//It also handles calling CloseHandle for the copy.
WindowsIdentity id = new WindowsIdentity(tokenHandle);
CloseHandle(tokenHandle);
return id;
}

[DllImport("advapi32.dll", SetLastError=true)]
private static extern bool LogonUser(String lpszUsername, String
lpszDomain, String lpszPassword,
int dwLogonType, int dwLogonProvider, ref IntPtr phToken);


[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
private extern static bool CloseHandle(IntPtr handle);

//And I call it this way:::::

WindowsImpersonationContext wic = CreateIdentity("sharepointadmin",
"Domain", "password").Impersonate();
SPSite spsite = SPControl.GetContextSite(context);
SPWeb site = spsite.RootWeb;
site.AllowUnsafeUpdates = true;
SPRole currentRole = site.Roles["CurrentRole"];
SPUser userAdd = currentRole.Users[@"cts\147458"];
UserGroup usergroup = new UserGroup();
usergroup.Credentials =CredentialCache.DefaultCredentials;
SPRole newEmulateRole = site.Roles["role To which i am shifting current
user"];
usergroup.AddUserToRole("role To which i am shifting current
user",userAdd.Name,userAdd.LoginName,userAdd.Email,userAdd.Notes);
usergroup.RemoveUserFromRole("CurrentRole",userAdd.LoginName);
usergroup.Dispose();
wic.Undo();

//end coding


<h><b>Now I come to the problem::</b></h>

I change the roletype and I redirect to the destination page..But the menu
displayed contains the pages ,
<b>both for previous role and new role!!!!</b>and even refresh don't help
me now.

one thing I will like to mention:
If In some other window, if I hit any page in "portal/_layouts/..." e.g.
"/_layouts/1033/error.aspx"

and now come back to main working window, our main discussion point,
<b>and now if I refresh it,
it works fine!!!!!!</b>
It shows menu iems only for changed role type...


Could anyone give me atleast some idea why its happenning so that I may
debug my problem

<b>one thing more I need to mention, this problem occurs in only clients'
network, in our development server
the same code works properly in every way!!!</b>

Sorry, this newsgroup is for questions about coding modules in VBA for
Access, the database product that's part of Office Professional.

Your code does not look like VBA, so you'd be best off reposting to a more
appropriate newsgroup, either one related to SharePoint, or one related to
the programming language you're using.
