Hi, I have been looking into the claim that the keyword lock is not safe when exceptions are possible. That lead me to try the following code, which I think has uncovered a serious error in the .NET 2.0 framework. Note that this runs better, but not perfectly, on .NET 1.1. Note: The numbers...more >>

Hi, I have added few of the events in some control, example code is: btnControl.GotFocus +=3Dnew EventHandler(EventHandlingMethod); btnControl.Click +=3Dnew EventHandler(EventHandlingMethod); lblControl.Click +=3Dnew EventHandler(EventHandlingMethod); private void EventHandlingMethod(object s...more >>

I'm not sure in which discussion this fits in, but I'll try here. I need to use Unicode in order to use national characters. But I find a strange behavior that I had not expected. I can't find much from the documentation about this. I need to know if a character is a letter or not. Even if i...more >>

In .NET 2.0 if you use AppDomain.GetCurrentThreadId then you will get a warning that the call is obsolete and you should use ManagedThreadId property of the Thread object. If you were to look at the AppDomain.GetCurrentThreadId() method and Thread.ManagedThreadId property documentation ...more >>

In .net 2.0, the dispose method of CryptoStream calls the Close method on the destination stream (verified with .NET reflector). In 1.1, it did not. In my opinion, the 1.1 behavior was preferable. After all, once I am done decrypting the data, I may want to look at it. Why should I have to k...more >>

Looking at the output of ildasm, I was wondering if there's a size limit on msil for any given method. The IL_xxxx index is an hexa number on 16-bits. Does it mean that for any given method, there's a 64 kb size limit? I know I shoudn't create methods so big, but let's say I want a 256 kb m...more >>

I am working on a project for my employer that will allow users to opt-in for a weekly email news letter. This is a company that has a high regard for their public image and I would consider this to be very legitimate. They are talking about sending a few thousand to possibly 10,000 emails eve...more >>

Hi, I am trying to debug an application, so I set a break point, and when I reach it, I want to exit the application by stopping the debugger. However, it seems that it runs to the end of the method that I am currently in. Can someone tell me why this happens and how I keep the applicatio...more >>

(Re: .NET Assemblies versions; I wanted to make this a new poat but OE shows it in the same thread as the original post, so excuse the repost if you see both as new threads) Reading the docs (http://msdn2.microsoft.com/en-us/library/db7849ey ) I see a note that states: "Version 1.0 .NET ...more >>

First of all, I'm using .Net Framework v1.1 with VS.NET 2003 I have made some tests, and I realized that "ldelema [mscorlib]System.Byte" doesn't work on my Pocket PC device if my buffer is declared as follow even if typeof(buffer) is Byte[]: SetDouble(class [mscorlib]System.Array buffer,.....more >>

What happens when on a .NET 2.0 application you reference a third party assembly that itself references the 1.0 versions of the .NET CL? (e.g. mscorlib 1.0, System.dll 1.0, etc.). Does the CLR automatically rebind those references to point to the 2.0 versions? I've tested this on a machine ...more >>

Hi, I'm trying to write a method for my PocketPC that will write a Double value to an Array buffer at the specified offset. The constraints are : - Must be safe managed code - Array buffer can be of any integral type (byte, short, int, long, etc.) - offset can be unaligned I already wr...more >>

Try running the following code (tested on .Net1.1 SP1) in both debug and release builds. Notice the different results: In the release build, Method B (which modifies an instance field) is never called!!! ------------------------------------------------------ using System; namespace Maj...more >>

I'm having a srange issue with events in my app. I am trying to embed Lua scriping using LuaInterface ( http://luaforge.net/projects/luainterface/ ), which basically allows Lua scripts to access CLR object, including their events.

Hi, I have a scenario where AppDomain.CurrentDomain.GetAssemblies () only return part of the loaded assemblies in that AppDomain. I know it is not complete, because the code doing this call is located in assembly B, which is called from assembly A, and in the result of GetAssemblies I do ge...more >>

I am seeing a strange behavior with a managed/unmanaged C++ program. The program is a large application made of DLLs, COM components, and an exe. When I recompile the exe with /clr a problem occurs: at some point, deep down the stack far from main() and far from the managed to native transiti...more >>

We are in the process of migrating from Beta 2 to the RTM version of Visual Studio 2005 and the .NET Framework. After the RTM version has been installed, Word and Excel no longer load the 2.0 framework for our C# addin, but instead version 1.1. For some unknown reason PowerPoint still loads ...more >>

I'm interested in the compatibility relation (used by the bytecode verifier) which involves the type "native int". So, is int32 compatible with native int? i.e. is int32 a subtype of native int? The few examples I run show that the bytecode verifier accepts an "int32" where a "native int...more >>

I am working with visual basic.net 1.1. I need to parse out data in a string that is space delimited. The number of spaces between each data item in the string can change.

I just started getting into this, so I hope this isn't a stupid question, but I noticed that the logging block has a feature for logging an additional chunk of contextual data using IDictionary (Hashtable usually).
