Is there any Memory Leakage ? or more  Load causing the problem ?

none of my knowledge. The servers are dedicated for our application. The problem does not occure on some heavy loaded machines, but on some with little load.

No, there is no timeframe or usageinfo that could lead to a analogy.<br />
<br />
C# calls a function in vb6 dll. In this function an sql-server is connected and a c++ dll is called.<br />
There are only strings passed.<br />

Hi<br />
<br />
we're using an Appartment Model Threaded VB6 COM component in a C# aspx webapplication. This works fine most cases. But sometimes it starts to throw COMExceptions. &nbsp;Only a applicationpool recycle helps to fix it.<br />
<br />
The error is:<br />
System.Runtime.InteropServ<wbr />ices.COMEx<wbr />ception: Automation error<br />
The callee (server [not server application]) is not available and<br />
disappeared; all connections are invalid. The call did not execute.<br />
<br />
Does anyone have a clue what could be the case here?<br />
Why could this happen?<br />
<br />
This happens on a Windows 2003 Server with .NET Framework 2.0 SP1<br />
<br />
Thank you!<br />
Regards!

COMException by accessing vb6 DLL from ASP.NET

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Editors IDEs

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
