{ End Bracket }: Improving Managed DirectX Performance


It seems that at least twice a week, I am asked about poor performance in Managed DirectX®. This frequency is actually a big improvement over the 5-10 times a week I was asked a few years ago when the technology first came out.

.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.

Web Part working fine on the top-level page but 'Not Safe' error on lower-level pages.


I have created a Web Part which reads and parses the SharePoint logs in order to display usage information of the page it resides on.  The Web Part works perfectly on the top page, reading and displaying the information desired.  However, once the Web Part is added to any page lower in the site heirarchy (sub-page) the same Web Part throws the following error:

Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.

Of course the current version of the Web Part is in the SafeControls list on the web.config.

The Web Part was originally designed to return site activity only for the top default.aspx page and worked fine but started to fail in the manner described above once I added the following line of code to return a SPCo

Why is the Content by Query Web Part CommonViewFields attribute not working as expected?

I am using the Content by Query Web Part to show data from a Custom List.  I have already added to the XSL "ItemStyle" sheet so that I can pick the correct Item Style.  That has worked fine - I have been able to show whatever fields I would like and apply any CSS Styles I would like to them.  The issue I am having is in formatting the field correctly.  I have two different fields in my current example that need to be formatted: [1] I want to show an Image, but right now it shows the URL  [2] I want to show Rich Text, but right now it shows all the HTML Code as Plain Text.  I have looked at many articles online, and they all tell me to change the following in the WEBPART file from: <property name="CommonViewFields" type="string" /> to: <property name="CommonViewFields" type="string">Thumbnail, Image;Teaser, RichHTML;</property> What I am doing wrong?  The Web Part still runs, but it does not format the fields any differently.  Thanks for the help!

Help with part of my footer not working right in IE7

I have two div's that make up my footer... One has a list of hyperlinks the other has a copywrite.  The hyperlinks css works fine and falls right after the content of the page. However the copywrite div does not work in IE 7 it seems that the float left does not seem to be working... Can someone give me some suggestions on how I can get this div to stay at the bottom of my page too..  #Copywrite { font-family: "Trebuchet MS", Arial, Helvetica, sans-serif; font-size: 50%; margin-left: 12px; text-align: left; float: left; width: 180px; clear: left; position: relative; } #hyperlinksList { font-family: "Trebuchet MS", Arial, Helvetica, sans-serif; font-size: 70%; text-align: right; float: right; margin-right: 12px; margin-bottom: 12px; width: 575px; clear: both; color: #0076CC; }  

Target audiences not working in excel services web part

My appologies i posted this originally in the pre-2010 forum So i'm reposting here: We have recently upgraded to Sharepoint 2010 and we're experiencing problems with the "target audience" field being available to the users. I am not the CA admin though so it'll make this a bit tough to get solved if the problem is there. What i'm looking for are the suggestions of things for me to forward to the CA admin to change or check if anything. We have a seperate Virtual Machine that is running 2010 that has this option available to users on that farm for some reason. however on our corporate farm we don't have that option available. Plus on top of this the quick launch items are not working with audiences as well to turn off the headers to links that have nothing in them due to security trimming on document libraries. I'm hoping that this being a more of an overview of things to check would help others who may have this problem as well. I've seen resolutions such as rebooting the server and such, however that's a bit lower level and we need some higher level things to check that may resolve the issue. Think the simple stuff first to check and lets work down the list. Doesn't matter how stupid it is but can we get a more compiled list of things to check to make sure that target audience visibility to users is enabled? Thanks!

Slow performance when searching in "any part of field" of a SQL Server database using a Microsoft Ac

We have just migrated our back end database from Access to MS SQL Server 2008 R2. We have noticed better performance on our searches - unless we select to search in "any part of field" in Access (with Access' built-in search function - we use a mix of Access 2003 and 2007). This takes nearly 20 seconds to find the result, whereas before the migration it was taking 5-7 seconds (compared to instant results we now experience when searching for whole fields). The main fields we search are not large - usually just two words. Obviously it is better to search for a whole or start of a field, but this is not always possible. The contractor that assisted us in this project has told us that this "is just the way SQL works with Access". Is this really true? I find it hard to believe two MS products would have such a big issue between them. I presumed using SQL with an Access front end would be a common setup, which is why I thought this must be a problem with our setup. Is there any way to fix this speed issue?

Improving performance of UPDATE CUBE by executing preceding CREATE CACHE for the same cell / subcube

Hi All, Recently I came across one of suggestions by Microsoft Advisory consultant regarding optimization data write-back pattern for the SSAS cubes. It was recommended issuing CREATE CACHE command following by UPDATE CUBE for the same cell/subcube definition: CREATE CACHE FOR [MYCUBE] AS ("Cross join of all the dimension members defining subcube to be updated") UPDATE CUBE [MYCUBE] SET ("Cell") = 100, ("Another Cell") = 200,... etc. for every cell. This seems quite weird, but based on our benchmark the entire process (CREATE CACHE and UPDATE CUBE) takes less time than just UPDATE CACHE. Folks, can someone advice on the insights of the process? Shell this approach to be suggested for an enterprise-level planning application? Regards, -h
