Configuration exception when migrating a ASP.NET application to a Azure webrole

by Damiaan Peeters 31. March 2011 01:50

Ok.  I found why I got a configuration exception every time I launched my azure project (in visual studio 2010). 

I have installed Azure Tools 1.4, on my Visual Studio 2010 SP1.

The problem

When I launched the appFabric / Azure Compute Emulator, I got a my visual studio telling my that I he didn’t have any trace or disassembly information. 

The most annoying part of this situation is that my WebRole Entry point wasn’t started neither.

This was the error (cut some path’s out to keep it readable).

System.Configuration.ConfigurationErrorsException was unhandled

Solution

So what does it mean.  If you open up the config file mentioned in the (inner) exception. You might notice this is not a complete configuration file.  For me it was my App.Settings file. 

What I did?  I moved my app.Settings into my Web.config file.  And gone was the error.

I think this is a bug. So, I posted it to Microsoft Connect so you can review it overthere:

Configuration of MySQL 5.5 on Websitepanel

by Damiaan Peeters 11. March 2011 19:36

So I followed these steps to activate MySQL 5.5 on our websitepanel deployment.

The current version of Websitepanel (1.1.0) doesn’t support Mysql by default.  However, with a few small changes you can get the Mysql version 5.5 to work.

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
<assemblyIdentity name="MySql.Data" publicKeyToken="c567fc88969c44d" />
<bindingRedirect oldVersion="0.0.0.0-6.3.5.0" newVersion="6.3.6.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>

  • Finally add and update the MySQL configuration in website panel.  These where the values I used
    • Internal Address: 127.0.0.1:3306
    • MySQL Installation Folder: C:\Program Files\MySQL\MySQL Server 5.5
    • Database Browser Logon URL: http://phpmyadmin.ourdomain.com/index.php
    • Root login: root
    • Root password: our root password

There is still a bug with deleting the database.  There are solutions available for this problem, but it’s not urgent for me.  So I didn’t tried it.

Change Keyboard layout in Windows XP and Windows Server 2003 at logon screen

by Damiaan Peeters 10. May 2008 08:53

While you had to Cannot log on after changing keyboard settings, you can now just configure it.

All you have to do is:

  • Open control panel
  • open the regional and language options
  • go to the advanced tab
  • Activate the "Apply all settings to the current user account and to the default user profile"
    image
  • Press Apply or OK, log off and you will see that the keyboard has the layout you wanted...

The same solution is valid for Windows XP.

Auto completion in Dos Prompt (cmd.exe)

by Damiaan Peeters 27. February 2008 14:14
It can be very annoying if the "auto completion" method not not available in the Windows XP Dos Prompt (read: command prompt).

If you type: cmd /f  it will be activated for the current session.  If you want to activate it on a pc (or change the key which is by default TAB), then visit the link.
