Roles-Aware Server Controls [Roles-Aware Server Controls]

mrichman — Thu, 17 May 2007 20:55:48 GMT

I know how to restrict access to given pages and paths by role. What I'd like to do is restrict content like server controls by role on any arbitrary page, or even alter which "view" is presented by role. Is there a design pattern for this? Also, how can this be done without hardcoding the roles in the code?

Thanks,
Mark

Exception has been thrown by the target of an invocation (HRESULT 0x8000500F) [Exception has been thrown by the target of an invocation (HRESULT 0x8000500F)]

mrichman — Tue, 23 Jan 2007 13:06:31 GMT

I've tried these command lines:

adsutil.vbs create_vserv W3SVC/2

adsutil.vbs create W3SVC/2 "IIsWebServer"

but I'm getting 0x8000500F ("Exception has been thrown by the target of an invocation")

I also get the same exception when calling this from C#:

DirectoryEntry site = (DirectoryEntry)root.Invoke("Create", "IIsWebServer", 2); // or any value for Site ID

I'm running both scenarios as domain admin.

Any ideas?

Thank you,

Mark

Custom nav toolbar using sitemap roles [Custom nav toolbar using sitemap roles]

mrichman — Sat, 30 Sep 2006 22:50:10 GMT

I have the following nav template:

<asp:Repeater ID="TopNavRepeat" runat="server"
DataSourceID="SiteMapDataSource1">
   <HeaderTemplate>
      <ul>
   </HeaderTemplate>
   <ItemTemplate>
      <li>
      <asp:HyperLink ID="HyperLink1" runat="server"

      </li>
   </ItemTemplate>
   <FooterTemplate>
      </ul>
   </FooterTemplate>
</asp:Repeater>

How do I render the <li> for only those sitemap nodes for which the user's role has access? (i.e. roles="Admins" in Web.sitemap)

ul li based menu - setting css class dynamically [ul li based menu - setting css class dynamically]

mrichman — Sun, 24 Sep 2006 18:15:09 GMT

I have the following nav menu:

<li><a href="/foo/orders/" class="">Orders</a></li>

<li><a href="/bar/catalogs/" class="">Catalogs</a></li>

<li><a href="/baz/suppliers/" class="">Suppliers</a></li>

<li><a href="/bam/storefronts/" class="current">Storefronts</a></li>

</ul>

</div>

How do I set the class of the anchor based on the current location? Also, this should apply when browsing any subordinate pages, i.e. /foo/bar/default.aspx and /foo/bar/something.aspx should both set the current location in the nav menu.

Thanks,

How do I update the metabase via .vbs or .js to add an HttpRedirect on a new virtual /foo for each website in my metabase? I have about 2100 websites, so this will need to be automated.

Thanks!

My boss sent this email out to the dev team. It seems a bit draconian to me, and quite condescending...how would you respond?

I’d like to make one thing very clear. Nobody should be writing code without a plan. This means written documentation (usually a design document) on what is to be done including but not limited to system and component description, test cases, programming interfaces and use cases where appropriate; what is to be done and why it is going to be done.

The design should be reviewed as appropriate: in a meeting and/or by your peers, by architecture and by [John Doe] or me. Before you complete the document(s) it/they should be re-read for coherence and checked for errors. Don’t think about the minimum you can get away with but instead what you’d want to see if someone else was writing.

In no uncertain terms, I don’t want to find anyone coding before design has been done – this implies that if there is more than one person on a project that all of the design must be coordinated and complete. If there are any exceptions to this they must be approved by [John Doe] or me respectively.

ASP.NET Session Timeout Ignored [ASP.NET Session Timeout Ignored]

mrichman — Thu, 08 Jun 2006 17:16:12 GMT

I am trying to alter the session timeout for a simple ASP.NET app.

In my web.config I set this:

<sessionState mode="InProc" timeout="60"/>

I set the start time in session_start:

void Session_Start(object sender, EventArgs e)

{

Session["StartTime"] = DateTime.Now;

}

Then, I refresh the page every second, displaying the session id and elapsed time for the session:

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

protected void Page_Load(object sender, EventArgs e)

{

DateTime startTime = (DateTime)Session["StartTime"];

TimeSpan ts = DateTime.Now.Subtract(startTime);

lblTimeSpan.Text = ts.Seconds.ToString();

}

</script>

<title>Untitled Page</title>

</head>

<body>

<div>

Session ID <%= Session.SessionID %> has been active <asp:Label ID="lblTimeSpan" runat="server"></asp:Label> seconds.<br />

Session.Timeout = <%= Session.Timeout %>

</div>

</form>

</body>

</html>

Every time, without fail, no matter what I do to try to manipulate Session.Timeout, the session expires after 60 seconds!

SQLEXPRESS on Vista x64 Beta 2 [SQLEXPRESS on Vista x64 Beta 2]

mrichman — Wed, 31 May 2006 17:19:19 GMT

I'm trying to add a databse to App_Data via Visual Studio 2005 under Vista x64 Beta 2. I get this error, "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed."

Poking around, I found this article, but it doesn't seem to help. I have deleted the C:\Users\<username>\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS folder and restarted, but when SQL Express starts back up, it recreates that folder and the error still occurs.

sseutil -l produces the same error as well.

Any ideas would be appreciated.

SDDL Question [SDDL Question]

My question is, what is the difference between OICI and OICIID? I realize this is Object Inherit + Container Inherit + Inherited, but I'm not 100% clear on the meaning of "Inherited" with respect to OICI.

Basically, I need to grant user jdoe read access to folder \foo, but read+write+delete access to any child object of \foo. For example, read the contents of \foo, but delete \foo\bar.txt, or create dir \foo\bar.

Thanks,

Exception parsing web.config when specifying <configuration xmlns="..."> [Exception parsing web.config when specifying <configuration xmlns="...">]

mrichman — Wed, 19 Apr 2006 15:06:18 GMT

I am parsing the value of my forms auth timeout in the /configuration/system.web/authentication/forms element of my web.config as follows:

string webconfig = Request.ServerVariables["APPL_PHYSICAL_PATH"].ToString() + "web.config";
System.Xml.XmlDocument x = new System.Xml.XmlDocument();
x.Load(webconfig);
System.Xml.XmlNode node = x.SelectSingleNode("/configuration/system.web/authentication/forms");
int timeout = int.Parse(node.Attributes["timeout"].Value, System.Globalization.CultureInfo.InvariantCulture.NumberFormat);

This code works fine, unless I specify a namespace for the <configuration> element:

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

In this case, SelectSingleNode() returns null. Omitting the xmlns="..." directive allows the code to work without an exception.

What am I doing wrong?

Delete all aspnet_* entries for a given ApplicationName [Delete all aspnet_* entries for a given ApplicationName]

mrichman — Fri, 07 Apr 2006 18:45:11 GMT

Is there an easy way to delete all ASP.NET applications services db entries (aspnet_* tables) for a given value in aspnet_Applications.ApplicationName?

ASP.NET apps (using the default provider) create entries in the following shared tables:

aspnet_Applications
aspnet_Membership
aspnet_Profile
aspnet_Roles
aspnet_Users
aspnet_UsersInRoles

I'd like to be able to nondescructively "uninstall" one ASP.NET application without disturbing another's data, where several apps may share a single database instance.

Factoring Interfaces for WCF (Indigo) [Factoring Interfaces for WCF (Indigo)]

mrichman — Tue, 21 Mar 2006 14:16:04 GMT

I am embarking on my first WCF (Indigo) based service. This service will be evolved from an existing .asmx based set of web services that expose over 200 webmethods. My question is, what is the best way to (re)factor the .asmx interfaces in WCF? I was considering a single IMyInterface containing the 200+ methods, and then perhaps partial classes for the implementation to maintain some modularity. Is this a bad idea? Are there any best practices for factoring WCF interfaces?

Using @ symbol in DSN UID= [Using @ symbol in DSN UID=]

mrichman — Wed, 15 Mar 2006 16:16:09 GMT

Yes, I know I should be using DSN-less connections. But, I was just playing around with using UPN syntax usernames in DSNs, and came across this behavior. The following fails to connect:

cnnTest.Open "DSN=mydsn;UID=user@domain.com;PWD=password;DATABASE=mydatabase;"

while concatenating the @ works fine:

cnnTest.Open "DSN=mydsn;UID=user" & "@" & "domain.com;PWD=password;DATABASE=mydatabase;"

Does anyone know why this could be?

Ruby on Rails vs. ASP.NET Deathmatch!!! [Ruby on Rails vs. ASP.NET Deathmatch!!!]

mrichman — Thu, 09 Mar 2006 12:43:38 GMT

I knew that subject would get your attention :)

I've never programmed in Ruby before, but I just watched these impressive presentations on Ruby on Rails, and I would love to see the ASP.NET community counter with demos of their own:

http://rubyonrails.org/screencasts

While Ruby on Rails may seem to allow one to get a simple app up and running quickly, ASP.NET has a whole lot less *total* code, even if it may take a bit longer. For example, I bet that blog demo can be done in ASP.NET with one .aspx file with little or no code-behind and a web.config, plus an .mdf.

Symfony looked cool too: http://downloads.symfony-project.com/demo/cart/cart.mov

Thoughts?

I'm using the new Web Deployment Project, and I'm having an issue.

The aspnet_compiler doesn't seem to be generating code for my Login.aspx.cs class. When I browse my compiled site, I get this error, "System.Web.HttpException: The file '/Login.aspx' has not been pre-compiled, and cannot be requested."

Target AspNetMerge:

However, Login.aspx.<blah>.compiled shows up in the \bin folder.

Is there any way to get more fine-grained control over these tasks? I am tempted to dump the .wdproj solution for my own .proj file using the <AspNetCompiler> task.

Incidentally, I'm also using the Zip and Version tasks from http://msbuildtasks.tigris.org/ with acceptable results.
