I'm trying to diagnose the cause of excessive induced garbage collections in our app. In the past, this has been easily achieved by setting a breakpoint in System.GC.Collect and looking at the call stack. However, when I attempt to do this while attached to our application, I get the message "...more >>

Hello, I have a Logitech .NET 1.1 application that gives an unhandled exception when .NET 2.0 is also installed on the same machine.

Windows Server 2003 Service Pack 1 causes the System.Threading.Timer to not fire, sometimes immediately and sometimes after a while. Once a timer dies, it will never fire again.

I've been having problems getting to the ROTOR source at the University of Pisa for about a week now. Access is sporadic at best. Luckily I've been able to find what I need in Google's cache. Are they having problems? Are they taking it offline permanently? Or maybe they're blocking acc...more >>

Hi, I am diagnosing a strange problem in .NET service (written in C#, framework 1.1 with sp1 installed - 1.1.4322.2032). Service is multhithreaded (heavily) and takes huge load (in CPU time, memory consumption and IO load). Service uses remoting to expose some interfaces and makes a lot of calls...more >>

Hi, I have developed a .Net application in C#, use Visual Studio 2003 (.Net framework 1.1). I am testing that it installs and runs OK on Windows XP (which is what it was developed under) running under Virtual PC. It runs fine on developer machines and appears to install fine under V...more >>

Hi! In a previous post I discussed the most suitable approach for multi-threading in a provided scenario and was provided very usefull feedback (thanks Stefan Simek, Jon Skeet and John Conwell). I am using a WaitHandler.WaitAll to wait for all of my threads to finish executing, but I wo...more >>

Hello, I have a COM interface which has the following method: HRESULT Item( [in] DWORD dwIndex, [in] DWORD dwWhichName, [in] DWORD cchLength, [out,size_is(cchLength)] LPSTR pszName ); When I create a Wrapper-Dll with midl.exe and tlbimp.exe, this method is converted to: publ...more >>

Simple question :- On a web server I sometimes see the error Item has already been added. Key in dictionary: "MethodName" Key being added: "MethodName" I'm using CallContext to store information.

What I want to know is; do all shell executed .NET app run in the same process? For that matter do all runtime-hosts run all of their app-domains in the same process? In the case of a shell executed application here's my understanding: Double clicking a .NET executable file invokes a runtime h...more >>

This problem occurs after system has been fully initialized and main form is displayed. Calling 'Trim' method during initialization causes no problem. I tried to avoid using this method but some framework classes use it as well. For example 'DataView.Sort' property uses it according to call s...more >>

Hi, In one of my classes I have a method, lets call it Fetch, which will collect data from various sources and return the combined result. Each of the sources can take between 5-15 seconds to collect so I would like to incrcease the performance by introducing multi-threading support for t...more >>

This is too weird. You're going to love this one. I just ran across the most bizarre DotNet "feature" with the String.Split() method. You are supposed to pass it an array of characters to tell it what separators to split the string on. if it finds any of those characters, it treats that...more >>

Something I can't quite get out of the docs, is what the 'normal' way is to implement a service's main body. My service collects data from network-attached devices at regular intervals, so it's basically an endless loop with a Thread.Sleep() for timing. Do you start a worker thread in OnS...more >>

Hello All, I have written an application to process a file full of XML. For each "main element" in the xml file, the application parses it and writes the resulting object to an Oracle database. Here is the problem. In an XML file with 20000 objects, running as a service, the silly thing ...more >>

When writing a file using StreamWriter, I'm having difficulty handling the "out of disk space" IOException. When catching this exception: - if I call Close() on the StreamWriter, it fails with the same IOException ("There is not enough space on the disk.") - if I call File.Delete(), it fails...more >>

I have the following instruction in C++.NET : x = log10(n); int y = (int)(x * h); where x, h, n are of type double, and x receives the value NaN (because the value of number is rather small). This results in y having value of the largest negative 32-bit integer. What does the sta...more >>

Hello, I am often using XML serialization to deserialize type values from XML files. Recently I came across the exception thrown by Framework when I try to cast serialized class from object to a type. The following happens: 1. I read type using XmlSerializer into a generic "object" instanc...more >>

It seems that x.CompareTo(y) returns -1, 0, or 1 when x and y are int, long, uint, float, double, string, or DateTime types, depending on whether x is less than, equal to, or greater than y. But when x and y are sbyte, short, byte, or ushort types, the return value is y-x expressed as a signed...more >>

I used to create services in a 'self-installing' way: a single executable that serves both as the service executable and as configuration/install program.
