Peter, Where you answering my question, or did you answer another question? Because I have no idea how PInvoke and COM-wrappers could solve the issue I have with hanging Oracle client applications.

[mailto:[EMAIL PROTECTED] Verzonden: donderdag 2 februari 2006 14:29 Aan: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Onderwerp: Re: [ADVANCED-DOTNET] Oracle client hangs after network error You would have to convert your lib project(s) to DLL project(s) in order to P/Invoke them from C# (or any other .NET language). The alternative, as you may have noticed, is to create a COM wrapper for the functions (again, probably within a DLL) and have Visual Studio reference the COM object(s). http://www.peterRitchie.com/ On Wed, 1 Feb 2006 17:50:58 +0100, Joris Zwaenepoel <[EMAIL PROTECTED]> wrote: >Hi all, > > > >I have a problem with a VB.NET application that sometimes hangs when a >network error occurs.
