Junfeng Zhang's Windows Programming Notes

If you have a lot assemblies loaded in the appdomain, you may experience slow appdomain shutdown, coupled with CPU spike. This thread explained why. http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.dotnet.framework.performance&mid...

We have shipped several versions of .Net framework: 1.0, 1.1, and 2.0 is on the horizon. All of them are side by side, meaning, someone may be using 1.0 CLR, at the same time, someone else is using 1.1 CLR. In the same process, there can be only one CLR...

Java 1.5 introduces class data sharing: http://java.sun.com/j2se/1.5.0/docs/guide/vm/class-data-sharing.html This looks a lot like .Net's ngen concept, except it only works on core classes(for .net's equivalence, mscorlib.dll). Maybe their next...

Brian Grunkemeyer from BCL team answers one question about mscorlib.resources here: http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.dotnet.framework.clr&mid=586edffa-c09d-470d-ba23-a99832acabfa

KB article 329065 describes how index services can affect ASP.NET. The root cause of the problem is CreateFile flag FILE_SHARE_DELETE. When the flag is specified, you will be able to delete the file, even it is in use by other applications. The...

By default fusion uses IE cache for the binding log. If IE screwd up, fusion can't write/read binding log from IE cache. If that happens, you can clear IE cache, and fusion binding log should work after that. Of course, if you use custom log...

http://www.eweek.com/article2/0,1759,1560543,00.asp Microsoft Visual Studio.Net 2003, Windows Server 2003 and Office OneNote 2003 are among the winner list. In addition, Office SharePoint Portal Server 2003, System Management Server 2003, Windows Right...

For applications running under WOW, they can't delete a reg key under 64bit hive using RegDeleteKey. They have to use RegDeleteKeyEx . RegDeleteKeyEx exist in advapi32.dll, only in 64bit OS.

Fusion Global Assembly Cache API is not documented in MSDN, but it is documented in KB article 317540 http://support.microsoft.com/default.aspx?scid=kb;en-us;317540 . I have received many questions about how to use fusion APIs. In the coming weeks...

This is really about Win32 on Win64, or Windows on Windows, or short for WOW. MSDN has many information about 64 bits Windows here ( http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnanchor/html/64bitwindows.asp ). One particular piece...

Alan has a great discussion on assembly binding policies here ( http://blogs.gotdotnet.com/alanshi/commentview.aspx/d4edb084-c625-4b6e-8e5c-7c2580cfcee9 ). I'll just talk about publish policy here. MSDN documents how to create a publisher policy here...

Jim Hungunin posted a paper about an implementation of Python for .Net IronPython: A fast Python implementation for .NET and Mono http://www.python.org/pycon/dc2004/papers/9/IronPython_PyCon2004.html In this paper, he started out trying to show...

Alan writes a blog to rebut Chris Sells' “ Avoid the GAC ”. Chris does have a point to avoid the GAC for casual application developers. The problem is he over-extended his argument to say GAC should be avoided for all the cases. Windows...

This is a follow up of my previous post. Ngen.exe accepts options like “ngen app.exe asm1 asm2 ...”, where asm1/asm2 can be display name, or file path. If you use this syntax, ngen will compile all the assemblies in the context of app.exe...

Jeffrey Richter is easily one of my favorite authors. His book “Programming Applications for Microsoft Windows” is still the most comprehensive Win32 programming guide book. And his book “Applied Microsoft .Net Framework programming”...

News coverage here: http://news.com.com/2100-1003_3-5180359.html?tag=nefd_top . For people don't know, Lenovo is the biggest computer OEM in China. Honestly, this is one of the few times I see a China company on main page of news.com.

This is a very common Assembly.Load failure exception text. In fusion terminology, this is called Ref-Def-Mismatch. This exception is thrown when fusion finds an assembly that does not match what you are looking for. A very common mismatch is version...

This is by design. The reason is that assemblies installed in YOUR development machine is not necessary the same as what your application requires. Let VS to reference assemblies installed in your development machine is clearly not the right thing...

UCOMIStream interface is the managed definition for COM IStream interface. You can use it to interop with unmanaged IStream. It lives in System.Runtime.InteropServices namespace.

OpenThreadToken returns an access token for the specific thread. OpenThreadToken will fail with ERROR_NO_TOKEN if the thread is not impersonated. If you want to get the thread token regardless if the thread is impersonated or not, you should catch...

MSDN has a web based news reader for all the microsoft public newsgroups at http://msdn.microsoft.com/newsgroups/ . It is mostly Javascript driven. So if you want to copy an URL for a post, you can't right click and choose “Copy ShortCut”...

System.Exception has a protected property HResult. To read the property, use System.Runtime.InteropServices.Marshal.GetHRForException().

This is a post from CLR team to newsgroup microsoft.public.dotnet.framework.clr. "Jesse Kaplan" wrote in message news:404f59e4$1@news.microsoft.com ... > Platform Invoke Resources > > > > In our efforts to make the .Net platform continuously...

This is an interesting discovery I find when I was investigating a regression. The following code is really Assembly.LoadFrom AssemblyName assemName = new AssemblyName(); assemName.CodeBase = pathToAssembly; resultAssembly = Assembly.Load(assemName...
