Display ASP Menu Control in Chrome / Safari

I had a problem displaying the standard asp.net menu control in Google Chrome and Safari

I was using master pages

but if you modify the source file behind your master page and include the following

C#
protected void Page_Load(object sender, EventArgs e)
{
if (Request.UserAgent.Contains("AppleWebKit")) Request.Browser.Adapters.Clear();
}

VB.NET
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Request.UserAgent.Contains("AppleWebKit") Then
Request.Browser.Adapters.Clear()
End If
End Sub

UDF Class VB.NET Reset Connection String for Entity Framework

This is a useful class I've created mixing and matching code from the web.

But basically it allows you to reset the connection string for an entity framework and save the values to the current application configuration file.

To use, something as follows


       Dim uConnection As New uCustomConnectionString

' Connection String  Name
' Server
' Database / Catalog
' Username
' Password
        uConnection.SetDatabaseConnection ("db1001229_CountersEntities", "localhost\sqlexpress", "db1001229_Counters", "sa", "password")



----
Class

Imports System.Configuration
Imports System.Data.EntityClient
Imports System.Data.SqlClient

Public Class uCustomConnectionString
    Public Function SetDatabaseConnection(ByVal oConnectionString As String, ByVal ServerName As String, ByVal DatabaseName As String, ByVal NewUsername As String, ByVal NewPassword As String) As DialogResult
        Dim curConnection = ConfigurationManager.Conn…

Just working on a number of projects and I wanted a quick and easy way to check if mod_deflate(compression) originally mod_gzip is enabled for a paritcular web server running apache.

This web site has a number of useful tools to assist with this.

Microsoft All-In-One Code Framework

The Microsoft All-In-One Code Framework is a free, centralized code sample library provided by the Microsoft Community team.  Their goal is to provide typical code samples for all Microsoft development technologies.

You can view and download code samples from this link. You can also request code samples from Microsoft from this site.

Amazon Outage - What can you do

I think one of the biggest challenges facing any start-up is how to develop a sustainable DR strategy and plan which takes consideration of the current financial standing of the start-up. I also think many start-ups with good intentions discuss, explore and document DR strategies most appropriate to there business, but how many actually test or execute the DR strategy prior to a major outage. And it’s not good enough to just test the infrastructure, application and data You got to literally pull the plug. While many cloud vendors will claim that they can offer full redundancy and reliability its my opinion that all start-ups where it is financially viable should select two cloud providers i.e. primary and stand-by (DR). Interesting debate at CloudAve http://www.cloudave.com/11886/some-lessons-from-aws-outage/#comment-13688

NimbusDB Next Generation Database Platform

This looks really cool. NimbusDB. Its a combination of NoSQL and SQL, takes the best from both, combines them but plans to give developers a much more scalable database platform on which to build applications yet maintain the simplicity of using standard SQL Queries.

Watch Barry Morris, who is ex founder of IONA by the way.

Resize your VMWare Disks on CentOS

Modify you VM settings and increase the hard disk size for example add an additional 10GB.Boot systemRun fdisk and recreate partition #2fdisk /dev/sda2Issue the following commands D2NP2<enter> <enter>t28ewReboot Systemlvm pvresize /dev/sda2lvm pvdisplay # Take a note of the free PE (physical extents)lvm vgchange -a y lvm lvdisplay  # Take a note of logical volumelvm lvextend -l +320 /dev/VolGroup00/LogVol00resize2fs /dev/VolGroup00/LogVol00
You will need to tweak as  you go along.  In some examples above on the web, some people don’t do any reboot after step 4, but I needed to do a reboot.  Also after step 9ome people run an e2fsck, when ever I did this step 10 failed

Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine

I had a basic problem recently porting an ASP.NET application from 32 bit Windows 2003 to a virtual environment running Windows 64 bit.

The ASP.NET application was pretty basic and it worked with a MS Access backend.

I was using OLEDB Provider to connect from ASP.NET to the backend database

But as it turns out there is no version of JET for Windows 64 bit.

So you have to disable 64 bit ASP.NET under IIS and enable 32 bit ASP.NET under IIS.

Here are the steps I followed.

To run the 32-bit version of ASP.NET 2.0, follow these steps.  This was based on ASP.NET 2.0.50727

Start / Run  / cmdcscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET   W3SVC/AppPools/Enable32bitAppOnWin64 1%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -iNote One thing I missed, again simple but is to make sure that the 64 bit version of ASP.NET is prohibited and the 32 bit is allowed under the IIS web service extension list.

A Change from Zend, try Grails

I’ve been working with Grails for the past few months and I really like the platform.  Having worked with frameworks such as Zend, Grails comes as a breath of fresh air.
Grails is an open-source web application framework that leverages the Groovy language and complements Java Web development.

Its based on the MVC framework and it simplifies the work involved in getting your next web application up and running
