Re: [Firebird-net-provider] [FB-Tracker] Created: (DNET-571) Firebird DDEX Provider Visual Studio 2013 SP3 - Connection dialog disappears immediately

[Wolfgang L. <lem...@ps...>]

Hi Jens,

http://delphitutorials.de/VerbindungsdialogGehtZu

open Machine.config in 
C:\Windows\Microsoft.NET\Framework\v4.0.30319\config (or your config) 
and search for

<system.data>
     <DbProviderFactories>

there are more than one Entry for the Firebird Client:
<add name="FirebirdClient Data Provider" 
invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework 
Data Provider for Firebird" 
type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, 
FirebirdSql.Data.FirebirdClient, Version=4.5.0.0, Culture=neutral, 
PublicKeyToken=3750abcc3150b00c"/></DbProviderFactories>

delete one of the Entry....

Regards
Wolfgang
