Problems with ICorDebug and w3wp at Win64

Hi,

I'm writing an exception monitoring application using CLR interfaces.
My class implements
ICorDebugManage dCallback. When an unhandled exception happens in an asp
net page, my member function Exception gets called by framework. Most
of the time everything works ok. Nearly 99.99% of exceptions are
notified by CLR. But sometimes w3wp fails with the following message:

..NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error
(000006427F8863 38) (80131506)

This happens on 64-bit workstations only, including XPx64, 2003x64,
etc. I don't know the reason for such behavior. The last function being
called in mscorwks.dll is mscorwks!IsIPIn Module.
The error number corresponds to COR_E_EXECUTION ENGINE.

I don't have any clues to the reason of failure. Some guys reported dll
version problem with asp_isapi.dll and performance counters. My app
does use performance counters.

Could you please assist me in resolving this issue?

Hi to everybody, please forgive me if what I'm asking is obvious but I couldn't really find out any good pointers in a few hours of googling on the python site and related places. The question is: Does anyone have any advice on how to build Python on win64 boxes? We know it _is_ possible after we found Martin von Loewis's cool installer. The only catch is, we don't know how he got there :-(

We are having a problem which appears similar to a previous posting: http://groups.google.com/groups?hl=en&lr=&frame=right&th=d97f552e10f8c94c&seekm=OZw33z9EDHA.2312%40TK2MSFTNGP10.phx.gbl#link1 In the current release of our system, we decided to "wrap" the ASP.NET Session and Application objects to improve code clarity and accuracy. For example, instead of: Session = new SomeListClass;

Friends, We are preparing for Beta release of a new ASP.NET project, but our initial in-house tests are not going well. We have had W3WP.exe (and aspnet_wp.exe) die, and we feel we can monitor it's death and sometimes get useful information out of the DMP file. But lately, W3WP.exe lives, but appears hung. New request to the application hang unresponsive, existing user sessions are unresponsive, and eventually session timeout and go...

Hello, I created a Win64 build environment by copying from a Win32 environment, and modifying the Win32 macro to the Win64 macro. After that, the properties window does not load anymore and building or rebuilding does not work anymore. On one computer, which is a slightly newer install it does work.

As many people know, I think that garbage collection is a good solution for many memory allocation problems. I am aware however, that nothing is "the silver bullet", not even the GC. A recent article in slashdot http://developers.slashdot.org/article.pl?sid=07/11/17/0552247 proves that.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
