Emergency Notifications

r.claypool — Tue, 31 Aug 2010 02:15:12 +0000

I got a text message today from Nixle:

TBI: TEST AMBER Alert:

SUSP: John Doe 35 YO WM 06 Red Ford Mustang ABC123 1-800-824-1004

Distributing information like this to thousands of people in mere seconds is awesome! Now we just need a photo to go with it. I bet there is an iPhone app for that.

How to Delete Multiple Builds in Hudson

r.claypool — Fri, 11 Jun 2010 04:35:40 +0000

Hudson is great for managing scheduled builds, but after a while the artifacts start to take up a considerable amount of space.

Deleting them one by one is possible, but Hudson will do this for you:

Note that this works retroactively. If you have 300 old builds and set the job to keep just 20, the next build will delete 281 builds.

Installing Mercurial (hg) into Adobe Flash Builder 4 (standalone installation)

r.claypool — Wed, 05 May 2010 20:23:09 +0000

Flash Builder, Eclipse and Mercurial (Hg) are all new in my world, and I couldn’t find any instructions on getting them to play nicely together. If you are in the same boat, read on …

These instructions are based on a stand alone installation of Flex Builder, but I suppose they are about the same even if you are using the Flex Builder Eclipse plug-in.

Click Help > Install New Software …

Click ‘Available Software Sites’

Click Add
Enter a name and the url (http://hge.javaforge.com/hgeclipse), click OK

Click OK again to close the parent window and select ‘Mercurial Eclipse’ in the ‘Work with’ drop-down list.

Select HgEclipse and click Next, Next, Next, Finish

Now open a project. Right click the project, select Team > Share Project …

Share Project ..." width="412" height="295" />

Choose Mercurial (obviously) … click Next, Next, whatever, to finish the selections.

Finished! You should now see the Mercurial commands in the Team menu.

P.S. Mercurial ROCKS !!!! I’ve used VSS, Perforce, TFS and Subverion. Subversion has always been my favorite, but Mercurial easily takes first place now. The DVCS model is much better.

401.x errors on IIS: Authentication Required

r.claypool — Mon, 15 Mar 2010 13:15:48 +0000

Quick Tip: Is your site suddenly requesting a user name and password?

Most likely this is triggered by insufficient file system permissions. The error logs at
%SYSTEMROOT%\System32\LogFiles\W3SVC###\*.log will narrow down your search and give the substatus and Win32
error codes for each HTTP 401.

David Wang has a great write up about this on his blog. Check it out for more details.

My name:

Create your bar code at http://www.barcoding.com/upc/

T-SQL: Cannot drop the index because it does not exist or you do not have permission.

r.claypool — Mon, 01 Feb 2010 12:20:43 +0000

Quick tip: The table name and index name are required to drop an index, otherwise SQL Server will return an error.

e.g.

DROP INDEX [dbo].[IX_MyIndex]

fails with …

Msg 3701, Level 11, State 6, Line XX
Cannot drop the index 'dbo.IX_MyIndex', 
because it does not exist or you do not have permission.

However,

DROP INDEX [dbo].[MyTable].[IX_MyIndex]

will work fine if it exists and you have sufficient permissions. (Use Select user_name() to determine your user context, which will help to verify the permissions being used.)

Intellisense for NAnt Build Files (VS 2005 and 2008)

r.claypool — Mon, 18 Jan 2010 05:05:06 +0000

Step 1. Make VS recognize a .build file as an XML file.

Right-click a .build file in the “Solution Explorer” and select “Open With …”
In the “Open With” dialog, select “XML Editor” and “Set as Default”

Step 2: Enable intellisense for .build files.

Get the schema file for NAnt:

Version 0.86 Beta 1 is at http://nant.sf.net/release/0.86-beta1/nant.xsd
Version 0.85 is at http://nant.sf.net/release/0.85/nant.xsd

Copy it to the “xml\Schemas” subdirectory of your VS installation:

Note that you can check this path via Tools > Options > Text Editor > XML > Miscellaneous

Specify the schema to use within Visual Studio:

Open the file so that it appears in a Visual Studio editor window.
Click the file’s editor window (to activate it) and specify the schema to use (within the “Properties” window).

Note that this dialog has changed from VS 2005 to 2008:

(VS 2005)

(VS 2008)

If all of that is not enough, make sure to enter an xmlns and make sure it is equal to the xmlns specified in the XSD schema.

!!!!! Even though the schema is available at http://nant.sf.net/release/0.86-beta1/nant.xsd and http://nant.sourceforge.net/release/0.86-beta1/nant.xsd, you must reference the former url in your build file because it is the one referenced in nant.xsd. !!!!!

Here is an example of what I mean:

 version="1.0" ?>
 xmlns="http://nant.sf.net/release/0.86-beta1/nant.xsd" name="MyProject">
  
>

Hope that helps someone. Happy Programming!

Getting DataTables to work with ASP.Net MVC

r.claypool — Thu, 03 Dec 2009 07:13:12 +0000

Want to get jQuery DataTables to work in an ASP.Net MVC project ???

Here is a demo project in C# that should get you started. If I find the time, I’ll post details on how this was put together (but I think most developers will benefit more from running and stepping through the source code anyway).

Hope this helps someone. Happy Programming!

Viewing the Activity Log for VS 2010

r.claypool — Sun, 01 Nov 2009 20:41:07 +0000

Are you repeatedly getting a less than helpful error dialog in Visual Studio 2010?

Go to the command line and run devenv.exe with logging, reproduce the error in the IDE and then open ActivityLog.xml:

C:\>cd "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE"
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE>devenv /Log
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE>cd %APPDATA%
C:\Documents and Settings\username\Application Data>cd "Microsoft\VisualStudio\10.0"
C:\Documents and Settings\username\Application Data\Microsoft\VisualStudio\10.0>dir ActivityLog.xml /B ActivityLog.xml
C:\Documents and Settings\username\Application Data\Microsoft\VisualStudio\10.0>notepad ActivityLog.xml

Look for entries with type=Error, e.g.
