.NET Code Tuning: Make Your Apps Fly with the New Enterprise Performance Tool


Because the common language runtime (CLR) is a black box, it's pretty hard to divine what's going on when you want to track down performance problems. Microsoft will be delivering a brand new profiler, the Enterprise Performance Tool (EPT), as part of Visual Studio 2005 Team Developer Edition that's ideal for use on a production system because it offers some very lightweight means of collecting performance data. Here John Robbins takes you on a tour.

Mobility: Add Keyboard Support to Compact Framework Apps by Trapping Windows Messages


The Compact Framework Control class doesn't provide direct access to Windows messages. However, with P/Invoke, a few lines of native code, and the Compact Framework MessageWindow class, it's still possible to access underlying Windows messages. This can be used to work around any .NET Framework features, including keyboard support, that are not included in the Compact Framework.

Web-Aware Apps: Build Hyperlinks into Your Client App with the Windows Forms LinkLabel Control


LinkLabels are Windows Forms controls that enable a user to hyperlink to a URL that points to either the Web or the local directory system. While the SDK documentation discusses the control, it does not demonstrate how linking is accomplished, nor does it outline the power and flexibility the control provides. This article fills those gaps, showing how to link using the LinkLabel control. It also shows the flexibility of this control for the programmer using the .NET Framework. In addition, the author covers the large number of properties that allow you to customize your controls and accurately place them. Their built-in behaviors are also discussed, along with their use in both Visual Basic .NET and C#.

Windows 2000 Registry: Latest Features and APIs Provide the Power to Customize and Extend Your Apps


The Windows registry as it is recognized today first appeared in Windows 95. Its introduction simplified the storage of initialization information and made that data more secure. This article covers the history of the registry, the form it took in the early days, and its current incarnation in Windows 2000. Practical tips for managing data in the registry are outlined, along with descriptions of special keys, functions, and file types. Manipulation of the registry to customize both application behavior and certain features in Windows is discussed. Also covered are future directions of the registry, including the use of XML to store registry information in a hierarchical fashion.

making custom apps "cluster aware"

what proactive steps can we take to make our app (ado, stored procs etc) cluster aware, in the event that we someday use clustering?  For instance, I read things about retry strategies etc but dont even know if retry is on a different connection or what appears to be the same connection.  We already make our trans as small as possible.

Help make a bug aware to the IE9 team


Hi fellow developers.

Can you please test the following senario and submit your results to the bug report for IE9 Beta.

First install IE9. Then create a new win forms application and put a listview on a form (or simply open any current win forms project) and change the listview to have a background image. Now run the application and look at the listview, the background should wither be black or render invalid images (currupt pointer potentialy causing this).

You can then uninstall IE9 and the error will be gone. I belive the IE9 application updates the core Listview which is why when its uninstalled it corrects the issue, but any other input would be helpful for them.


Serving Silverlight Apps from Windows Mobile

Even if mobile dev is not my every day work, thanks to the .Net Compact Framework, it's still .Net programming.

Here is the scenario:

You come back home, you have a windows mobile phone wifi capable and you want to quickly get access to your phone pictures from your home network.
You just activate the Wifi, run my app and then browse to the provided link from any computer on the network.

Practical Multithreading for Client Apps

Writing applications that use multiple threads is often considered an advanced programming task, prone to errors. In this month's column, I'll focus on a practical application of multithreading in Windows® Forms applications with some real benefits, while attempting to keep things simple. My goal is to present multithreading in an approachable way that addresses a very common need: writing applications with a user interface that remain responsive to the user.

Beginner: this doesn't make sense to me


Do you need and "empty" script tag in the head to run scripts that are in the body?  Also, can you run JQuery scripts if they're in the <head> tag?  The first sample only works if the JQuery script is in the form (and body) tag, not in the head - even if I add $(document).ready(function() { });

This works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">
<form id="form1" runat="server">
<a href="">Here is a link</a>
<script type="text/javascript">
$('a').click(function () {
alert("you clicked me!");


This doesn't work.  Notice I removed the second <script> tag from the head

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="serve

Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont
