ldc.i4.s num | It says: Pushes num onto the stack as int32, short form. |
1. What we mean by short form here? Instead of 4 bytes 1 byte variable is created in stack for this int variable?

Hello all,
1. I have recently made a report to Microsoft Connect regarding a possible bug in the CLR code that handles COM events fired from unmanaged COM servers :
2. Since then, I have been doing research on the internals of the flow of event firing from an unmanaged COM server's IDispatch::Invoke() method call right down to the invokation of the managed object's event handler delegate function.
3. I have managed to find some interesting information about a ComEventsSink class from :
COMEventsSink.cs
4. This class provides an implementation for IDispatch and is used by the ComEventsHelper and the ComEventsInfo classes. Its Invoke() method provided very good info to me and there is a hint on why an event method which takes a SAFEARRAY reference parameter
winds up returning E_INVALIDARG (an ArgumentException exception is thrown).
5. I also had a look at the *_SinkHelper class declared in the disassembled IL code of the interop assembly generated by tlbimp.exe for an unmanaged COM server. I see that it directly calls the Invoke() method of the delegate with no reference to any ComEventsSink
object.
6. It is pretty clear that there must be some IDispatch implementation behind the SinkHelper class that gets called by the COM server event firing code.
7. Since the SinkHelper class is derived from System.Object, I believe that the SinkHelper probably inherits this IDispatch implementation of the System.Object class.
9.It is also possible that System.Object may internally use the ComEventsSink class to handle COM events.
10. I was wondering if anyone has any knowledge of this IDispatch implementation ?
11. Thanks, all.

Hello,
Is it possible to create a MSI Installer with VS2013 Community, or are there any restrictions since it is a free version of a VS.
In case it is ok, I would like to know to make it.
Thanks.

I have a 60+ second dynamic compilation delay showing up on multiple servers that seems to effect:
1. ASP.NET development (60+ delay after any html file change) (switching to the CodeDom roslyn compiler is my current work around)
2. MSBuild of most ASP.NET websites and web applications (CodeDom fix helps here as well)
2. SharePoint Site spinup (any site collection I access seems to have a 60 second delay right AFTER it runs code which adds a custom control to the top of my pages)
3. LaserFiche Workflow deployment (I assume due to a similar "runtime compilation" issue but haven't been able to prove that yet).
This seems like an extensive issue across multiple servers, although it is not ALL servers. I have done extensive comparison across these servers and applications and am unable to track down what the cause is. Anyone have any leads/suggestions for tracking down what might cause a dynamic compilation delay of multiples of 60 seconds (1 minute, or sometimes 2 or 4 minutes).
Thanks so much,

This very simple C# console program demonstrates a non-obvious bug relating to multi-threaded access to an object. Because this object is defined as an int most programmers tend to treat it as though it were a value instead of a reference to an object. Here's the sample code:
using System;
using System.Threading;
namespace PocAnonymousWorkerThreadSafetyExperiment
{
class Program
{
static void Main( string[] args )
{
for (int i = 0; i < 10; i++)
new Thread( () => Console.Write( i ) ).Start();
Console.ReadKey();
}
}
}
Here's an example of the program's output:
34446678910
The reason why the output is so flaky (that's a technical term) is obvious. The loop that creates the worker threads runs faster than the worker threads can be created and complete. Each worker thread is passed a reference to the object x and the value within x changes so the incorrect but intuitively obvious act of passing 'x' to each worker thread fails. Fine, that's pretty obvious. What follows next is not obvious.
using System;
using System.Threading;
namespace PocAnonymousWorkerThreadSafetyExperiment
{
class Program
{
static void Main( string[] args )
{
for (int i = 0; i < 10; i++)
{
int temp = i;
new Thread( () => Console.Write( temp ) ).Start();
}
Console.ReadKey();
}
}
}
And here's the output:
1203457698
The out of order part in understandable since there is no guarantee as to when a worker thread will start. The part that is not so clear is why does the output not duplicate or skip values? What's the difference between the variable 'i' that is part of the for loop and 'temp' which is defined as a variable within the loop? In both cases one may be excused for assuming that there is only one instance of each variable in existence but the 'temp' variable acts in a manner that is consistent with a new temp being defined each time we go through the loop. The older versions of 'temp' remain in memory and safe from garbage collection because of the outstanding reference to it in the worker threads but I'm just making up plausible theories at this point to support the observed facts. Can anyone tell me for a fact why version 2 of the sample doesn't have cross thread corruption of 'temp'?

I find this behavior strange. I have defined a managed enum and a class that uses it in a C++ managed wrapper as follows:
public enum class CvPlotType { None = -1, Mountains, Hills, Plains, Water };
public ref class CvPlotConnection
{
...
property CvPlotType^ Type { CvPlotType^ get() { return (CvPlotType)mTargetSimPlot->type(); } }
...};
The property above is seen as an "System.Enum" type when referenced in a C# project. I have to explicitly cast the c# variable as follows (GeoSimCoreController.Plot(x, y) returns a CvPlotConnection handle):
CvPlotType type = (CvPlotType)GeoSimCoreController.Plot(x, y).Type
What is going on here? I am really annoyed that the managed assembly does not cast the Type property properly.
We are experiencing periods of time when CPU utilization of our application goes to %100 percent for several seconds. I tracked this down to two CLR methods which are called when ‘new’ objects are created. The first being ?JIT_New@@YIPAVObject@@PAUCORINFO_CLASS_STRUCT_@@@Z. The second being ?JIT_NewArr1@@YIPAVObject@@PAUCORINFO_CLASS_STRUCT_@@H@Z. The size of the objects being created are relatively small. I understand that there is more to memory allocation then just getting memory, and that Garbage Collection might also be involved. I also understand that it might spike the CPU. But why would the spike last so long, upwards to 5+ seconds? Any insight would be greatly appreciated.
Thanks

Windows 2003 Server SP1, ASP.Net 2.0
BC30456: 'InitializeCulture' is not a member of
Have a bug in your code but throws this error instead of the actual error? Or getting this error randomly? Or a similar error complaining that an asp.net method is not a member of a class like 'Page' when it is!? and mashing refresh a few times sometimes makes it go away...
After 2 Days of extensive search on the internet and finding plenty of people with this error and very little replies and resolutions, I took upon myself to get to the bottom of this (unacknowledged ASP.net framework bug) and list some steps to help all of you work around it.
1. If you use Visual studio to publish your site, during the publishing stage on framework 2.0 uncheck the "allow this precompiled site to be updatable".
2. Ensure ASP.Net is installed correctly, I found that my Web Server root was configured to use ASP.Net 1.1 by default so ran the following line to fix it to 2.0 even though my site was configured for 2.0 at site level, eliminating this glitch seems logical.
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i
This will also fix any mapping/installation problems.
Also ran aspnet_regiis -r
This will replace all mappings recursively to 2.0 regardless.
3. Make sure page directives at the top of aspx files are correct and ‘inherits’ is pointing to your class correctly. I could not see any problems with mine, so did not explore down this path to thoroughly, but noted others saying issues with ambiguous inheritance maybe related.
4. Declare culture in your web.config, example
<globalization uiCulture="en" culture="en-NZ" />
OR
<globalization uiCulture="auto" culture="auto" />
5. Change debug="true" to "false" in web.config and any pages which have it set (I recommend removing it entirely from pages and just using web.config)
* This final step eliminated the problem for me, very weird.
Now if this last step eliminates the problem, and later on down the track you get an error in your codebehind file while coding or debugging, you will no longer be pointed directly to the line in your codebehind file when an exception occurs, asp.net will just show you the line in the aspx file you called from. Temporarily switch debug back to true in web.config if you can't figure out the problem and then you can see it, if InitializeCulture crops back up instead, mash refresh a few times like you used to do! Then turn debug back off.

Does anyone else have anymore info?
My question to Microsoft, why does this behaviour exist? Is it by design or really a bug? If so, why is there no acknowledgment of it as a bug for ASP.Net 2.0?

Hi all,
I´ve downloaded a third-party application wich is basically a Web folder with all the necessary elements to start working. That application is using a SQL Server database (2016 Express) and the server is a Windows 2012 R2 64Bit, the IIS is version 8.5.
The major of the functionalities of the application work fine, but there is a particular one that is crashed:
1. There are several items in a list (Table) with hyperlinks
2. When I clic an item, a second window is deployed, this window has several tabs with information related to the item.
3. One of these tabs enable the user to upload files and relate them to the item, and shows the list of document already uploaded.
4. Uploading files is not a problem, but when I try to download (clic the file in the list) I got the error described bellow.
Please take into account:
* I can't modify the application
* Parameter Enable 32Bit applications is true in Application pool
Event code: 3005-------------------------------------------------------------------------------------------------------------------------------------------------------
The code of the component highlighted above is:
using Microsoft.VisualBasic.CompilerServices;I'll be grateful if you give me a help.
Best regards.
i'm trying to do a little backup app that needs to comunicate with VSS Writers and do an incremental backup.
After some reading i now know that there are a few possibilities to do incremental:
More info HERE
This makes sense, but the writer i'm querying returns those 2 lists empty. Still makes sense because i gave no backup stamps to my writer.
The real problem is that even after a successful Full backup the Writer i'm using always gives null on
GetBackupStamp value. I set every component on success and completed the backup, looks like VSS is perfectly fine with my backup except for the missing Backup Stamp.
In my Writer's metadata i don't have the VSS_BS_TIMESTAMPED flag, so this is normal too (more info HERE ). This writer gave me those flag:
VSS_BS_INCREMENTALVSS_BS_COPYVSS_BS_WRITER_SUPPORTS_NEW_TARGETSo, i can do incremental but i can't use backup stamps, maybe. I like to think that the VSS_BS_TIMESTAMPED flag will appear if setup *something* correctly.
Every file to backup have those flags (more info HERE):
VSS_FSBT_FULL_BACKUP_REQUIREDVSS_FSBT_INCREMENTAL_BACKUP_REQUIREDVSS_FSBT_FULL_SNAPSHOT_REQUIREDVSS_FSBT_INCREMENTAL_SNAPSHOT_REQUIREDThis happen because i don't have a way to tell VSS Writer about my initial Full Backup (i have no backup stamp!).
If i try to set my backup as Incremental (since its supported by this Writer, i have the Incremental Flag in writer metadata) it fails
at PrepareForBackup(),
i still think because i did not set a backup stamp or some refeerement to the first Full Backup. I check this error in the Writer State, i have the flag VSS_WS_FAILED_AT_PREPARE_BACKUP (more
info: HERE)
TL;DR
And this brings me here, with this question: What i'm missing? There is some other way beside using Backup Stamps to do Incremental Backup with VSS?
I have an IL rewrite tool using SetILFunctionBody function, It working well under dotNet 2.0, 3.5 and 4.0
this month, I Got a SECURITY_E_INCOMPATIBLE_SHARE error under dotNet 4.6.0 , but I can't find more detail except the artical
https://msdn.microsoft.com/en-us/library/windows/desktop/dn720547(v=vs.110).aspx
I can't confirm my SECURITY_E_INCOMPATIBLE_SHARE error is the same as the error described in this artical, and I can't find any examples to use the ICorProfilerCallback6::GetAssemblyReferences interface.
Can anybody help me to give me some examples code to use the interface ?
thank you.
Hi,
I was working at a project using MEF1 which works fine for dynamically export metadata on different dlls.
Now I am moving forward to MEF2 in which I did not see much documentation on how to handle 'ExportMetadata".
Do I need to create concrete class for attributes for metadata? Could I still use this attributes in targeted class ?
Are there any good samples?
thanks
Maggie
