I created an application with Windows Forms connecting to Firebird, where on my development machine everything works perfectly, but when I put in client machine, the following error occurs:

  • how is your app.config ?

  • <configuration>&#xA; <connectionStrings>&#xA; <add name="MainBCUnitOfWork" connectionString="Server=192.168.7.162;User=SYSDBA;Password=a123456;Database=C:\Gerencial\Sans\Banco\geral.fdb;Port=3050;Dialect=3;Charset=ISO8859_1" providerName="FirebirdSql.Data.FirebirdClient"/> </connectionStrings>

  • on the client machine, is taking the library containing the Provider FirebirdSql.Data.FirebirdClient ?

  • then Rovann la in the client folder along with the dll needed to Firebirdsql.Data.Firebirdclient.dll this is also there...

  • in your customer app.config, the dll is registered in the section <system.data>?

  • Ricardo Punctual sorry for the delay and thank you for your attention, I’m sorry but I didn’t understand your question, and how I would do that ??
