I am using a Samsung laptop with NVidia GeForce FX Go5200 graphics chip.
Unfortunately the latest drivers are dated 2003 and so WPF won't use DirectX
even though 9c is installed and works fine. I've tried setting a later date
in the registry to no avail. Does anyone have any ...

I receive an error message: STOP 0x000000EA THREAD_STUCK_IN_DEVICE_DRIVER  
after updating my video driver. This also occurred before hand. I am using
windows xp service pack 2. Have tried to follow the hep from the microsoft
page. ie reduce hardware speed etc. all to no avail. ...

   I am trying to create a new web application.  I need some expert advice
on what all performance issues I might face.  Application has a rich UI and
also heavy DB access
Regards,

I've looked everywhere and can't find a fix, I get this error message on
start up and it seems to have slowed my start up down;
RUNDLL
C:\windows|system32|uibuykwd.dll

I know from running free scans that there's a lot of clutter on my registry.  
How do I clean it up?  How do I know I'm not deleting something important?  
Can it be done for free?
Thanks

I have a big application that is running ok in several machines.
In a clean machine with Windows XP SP2, with .Net Framework 2 or 3 (I test
both versions) I have a delay of 90 to 120 seconds on the start. From that I
make the double clic to show the first MessageBox.

Conversion to 2.0 (thro' vs2005) from 1.1, has made the app completely
unusable because of the performance degradation. It's a c# winforms,
multithreaded app, using datasets extensively.
I understand that  in 2.0 Dataset/dataTable have become more performant, and

I'm running a Windows 2000 server machine with .Net Framework 1.1 and
Commerce Server 2002.
Since the application we had was changed to make XML/XSL transforms we are
getting the ASPNET_WP process reaching 100% usage of cpu. Even with hardware

My app(winforms) runs from a network share and refers to quite a few config
files on the network.
I've two versions of the app., one running under 1.1 framework, and the
other under 2.0(2.0 version is the one converted from 1.1 through vs2005).

It seems that in some cases its quicker to clone an existing object vs
creating a new object. I have not done exstensive perf test but have found
cases where it helps.
Anyone have any thoughts on this?

I just converted a 1.1 app to 2.0. The app runs very slow, and cpu
utilization is almost 3 times. While investigating I noticed that the
additional time is spent in RT checks.  RT checks for 1.1 was 0.
App is compiled and run locally.

how much faster are unmanaged vs. managed arrays? (.net 2.0 framework)

Is there any improvements in performance for .NET 3.5?
All I hear about is the new features.
Thanks,
