Multiple connections to a server or shared resource by the same user

Wayne Larimore — Fri, 09 Jul 2010 17:04:51 GMT

Have you ever received this error message and scratched your head?

Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again

Since I run multiple virtual environments with the same logon credentials it used to happen to me all the time.

The solution is to use the IP Address or the full domain as demonstrated here:

Instead of \\SERVER1\Websites

Try this \\SERVER1.net\Websites OR \\192.168.30.1\Websites

Works like a charm.

"The unattend answer file contains an invalid product key" VMWare Windows Server 2008 Install

Wayne Larimore — Thu, 27 May 2010 12:43:37 GMT

I was prepping a virtual environment within VMWare Workstation 6.5 (EZInstall approach) for Microsoft SharePoint 2010. I encountered the following challenge when booting from a Windows Server 2008 R2 x64 ISO:

"The unattend answer file contains an invalid product key..."

To get rid of this show-stopper I simply disabled the floppy drive connection it had created. It worked like a charm.

How to get Eval ItemTemplate value from TemplateField

Wayne Larimore — Tue, 06 Apr 2010 15:07:38 GMT

If you want to retrieve a value produced by an Eval within an TemplateField within an ItemTemplate, this is how...

Here's the code:

string _id = ((DataBoundLiteralControl)GridView1.Cells[0].Controls[0]).Text;

Here's the Design View:

<asp:GridView ID="GridView1" runat="server" DataSourceID="sdsDataSource" DataKeyNames="ID">

  <Columns>

    <asp:TemplateField HeaderText="ID">

      <ItemTemplate> <%#Eval("ID") %></ItemTemplate>

    </asp:TemplateField>

  </Columns>

</asp:GridView>

It's Official - Upgraded Blog & New Diggs

Wayne Larimore — Mon, 16 Nov 2009 22:02:03 GMT

This past weekend I upgraded this blog. I run my blog on subText, a fork of the old .TEXT blogging platform. I went from version 1.9.3 to 2.1.2 and it wasn't a smooth migration path, let me tell you.

At the same time, I moved all of my websites (including this blog) from webhost4life to the fairly new WinHost.com. These guys are doing it all right. It fits exactly what I was needing and has cut my hosting cost in half. They bill on a monthly basis and have top quality support. The control panel is very simple but yet powerful. I went with the basic plan. However, they do provide an advanced plan as well. Some of the issues I ran across with my subText upgrade dealt with going from an IIS 6 platform to an IIS 7 platform. If anyone else is looking to do the same leave a comment and I'll fill you in on what I had to do to make it happen.

Anyways, I'm a happy camper now. Glad to have the migration behind me.

Virtual PC VMWare Alternative = Virtual Box (VirtualBox)

Wayne Larimore — Wed, 29 Apr 2009 21:38:53 GMT

If you believe Microsoft's Virtual PC has been abandoned or VMWare is too pricey for your budget, give the free Open Source alternative a try. I have been reading some forums and blog posts from some happy folks using it. Also, as of this posting date, the community is really active in keeping it cutting edge.

Virtual Box - http://www.virtualbox.org/

"VirtualBox is a family of powerful x86virtualization products for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL)."

ASP.NET Panel control generates Hot Pink background

Wayne Larimore — Tue, 06 Jan 2009 21:41:24 GMT

Anyone else come across this phenomenon? I thought something in my style settings was doing this at first. Then I started out from scratch. I created a new Website with a new webform. Introduced a GridView control and wrapped it up with a Panel control and printed it out. Hot Pink, baby! The culprit seems to be the Panel control.

[update] turned out to be related to the printer driver for the Ricoh printer line

Duplicate Items in DropDownList using AppendDataBoundItems

Wayne Larimore — Fri, 24 Oct 2008 03:46:19 GMT

Are you getting duplicate entries in your DropDownList control when using AppendDataBoundItems="true" and pulling in data from a datasource? This is one of those things that trips me up ever so often. The solution is to set EnableViewState="false" on the control. This prevents the previous items from being cached in the ViewState.

Hope this helps. If so, leave a comment of your experience.
