C++ Q&A: Get Logical Drives with VolInfo, Modifying the System Menu

Can I use folders instead of logical drives to separate data from logs if all data is on a RAID10 di


I've got six clustered SQL Instances storing data on a SAN, a SAN that is all RAID10.  It has one RAID10 disk pool.   Did it make any sense for me to create separate iSCSI initiators for data and log volumes?  I have no RAID5 space on which to store the data.  All the information gets the same high-quality access.


Could I have saved myself some time and just made one big disk for each instance, separating logs, data, backup, temp and master in folders?


When the data is sent, via iSCSI, to the SAN, the SAN director takes the data and does what it wants, irrespective of the operating system that sent it.  I think all the old rules of thumb go out the window.

ASP.NET Menu with jQuery Superfish

Choosing the right type of menu for a website is not easy at all. The ASP.NET Menu Control is definitely NOT a good starting point due to the horrendous markup it renders, nor is it good for SEO because of the Markup/Content ratio, neither can it be easily styled.

System Development Life Cycle

The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the spiral model. Mostly, several models are combined into some sort of hybrid methodology

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Logical- and Visual Tree

Elements of a WPF user interface are hierarchically related. This relation is called the LogicalTree. The template of one element consists of multiple visual elements. This tree is called the VisualTree. WPF differs between those two trees, because for some problems you only need the logical elements and for other problems you want all elements.

Problem making Role based Menu in MVC application



 I want to make Rolebase menu in MVC such that if user doesnot have permission for some action then that Action name shouldnot be shown in the Menu.

 I have used the code in the url(http://forums.asp.net/t/1566328.aspx) in my MVC application.My application is a Discussion Forum(in MVC) same functionality as in this forum forums.asp.net

 I have used Controllers for post, thread etc.In each controller there are some actions that are using [Authorize(Roles)] attribute

 but this coding does not count  those Actions in Controllers having Authorize attribute according to the url http://forums.asp.net/t/1566328.aspx 

 In the code, Authorize attribute is applied to Controller class, but my requirement is of Applying Authorize attribute to some actions in controller so that some are available for all users and  some links are available rolewise.Now what is the solution for that?



Problem upgrading to MVC3 - System.Web.Routing



I'm trying to upgrade to .NET 4 and MVC 3.

When trying to compile my project, I get the error:

Error 1 The type or namespace name 'Routing' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) C:\Users\spencer\Desktop\weblauncher\Common\MVCConfig.cs 4 18 Common

The type or namespace name 'Routing' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

I do have the System.Web.Routing in my references for the project.

BUT - when I try to view System.Web.Routing in the OBJECT BROWSER, nothing is inside!  The System.Web.Routing namespace is not in there - the entire thing is empty!  Could it that the dll is corrupted?  I tried to reinstall the .NET 4 and MVC 3 stuff, but its still empty!

The dll is coming from here:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Routing.dll

and the runti

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

Thanks in advance.

Can't get an Icon to show for Desktop shortcut and Program Menu



I've created a SetupWizard, but can't get it to show the Icon for the shortcut on desktop and program menu. The installation goes fine without any errors, the only problem is the icon.

I've made a shortcut of my exe file in the Application Folder and dragged the shortcut to the Desktop folder, then on the shortcut properties, I assigned it an icon picture located in Application Folder.

Any suggestions will be very much appreciated.

The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must



This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?


System.Xml.Linq.XElement and XPathDocument


I have an XPathDocument that I want to save to a table using LINQ, but I get this error

cannot implicitly convert type 'System.Xml.XPath.XPathDocument' to 'System.Xml.Linq.XElement'

I create the XPathDocument from some (valid) xml contained in a resource file

XPathDocument xDoc = new XPathDocument(new StringReader(Resource1.TestXML));

when I try to assign it with LINQ, it flags up an error

NewDataItem.XML = xDoc  ----  error here

NewDataitem is a LINQ to SQL object created from the underlying table, 'NewDataItem.XML' is a column type of 'XML'

how do i (easily) convert xDoc so I can pass it into the LINQ object ?
