tablasEstaticasDeUsuario.Tables.Add("Especificaciones");
tablasEstaticasDeUsuario.Tables["Especificaciones"].Columns.Add("UBICABLE",System.Type.GetType("System.Boolean"));

I'm using .Net 1.1, Fb 1.5 and Firebird Net Provider 1.7 maybe it works
with new versions?
Muchas Gracias.

But, then, I can't use DataAdapter to fill a DataTable with boolean
values instead char?

[Firebird-net-provider] Mapping a database char column to a DataTable boolean column
I wish to map a the "BOOLEANO" domain column as a boolean column in a
datatable.
CREATE DOMAIN BOOLEANO AS
CHAR(1) CHARACTER SET NONE
DEFAULT 'F'
NOT NULL
CHECK (value in ('T', 'F'))
COLLATE NONE
is it posible?
thanks, sorry about my bad english...

What was happen with this problem?
Becose I'm using 1.7 Provider, and I have a problem that seems to be
related:
Unhandled Exception: System.NullReferenceException: Referencia a objeto
no establecida como instancia de un objeto.
at FirebirdSql.Data.Firebird.FbDataAdapter.Update(DataRow[]
dataRows, DataTableMapping tableMapping)
at System.Data.Common.DbDataAdapter.Update(DataTable dataTable)
at PF.WinForms.Usuario.Form1..ctor(MmConnection conexion)
at sigeme.ContextoAplicacion..ctor(Boolean loginAutomatico)
at sigeme.ContextoAplicacion.Main(String[] args)
And my code is this:
dataadapter.SelectCommand = new FbCommand("Select NOMBRE, TIPO, VALOR
from SPESTADOSARTICULO(@IdArticulo)",connection);
FbParameter parameterTmp =
dataadapter.SelectCommand.Parameters.Add("@IdArticulo", FbDbType.Integer);
parameterTmp.Value = 1118;
dataadapter.UpdateCommand = new
FbCommand("CAMBIARESTADOARTICULO",connection);
dataadapter.UpdateCommand.CommandType = CommandType.StoredProcedure;
dataadapter.UpdateCommand.Parameters.Add("@IdArticulo",
dataadapter.SelectCommand.Parameters["@IdArticulo"].Value);
parameterTmp = dataadapter.UpdateCommand.Parameters.Add("@NombreEstado",
FbDbType.VarChar, 20);
parameterTmp.SourceColumn = "NOMBRE";
parameterTmp.SourceVersion = DataRowVersion.Original;
parameterTmp =
dataadapter.UpdateCommand.Parameters.Add("@Valor",FbDbType.VarChar,20);
parameterTmp.SourceVersion = DataRowVersion.Current;
parameterTmp.SourceColumn = "VALOR";
dataadapter.Fill(datatable);
datatable.PrimaryKey = new DataColumn[] {datatable.Columns["NOMBRE"]};
datatable.Rows[0]["VALOR"] = "0";
dataadapter.Update(datatable);
Well, maybe my code is bad, please correct me.
Thanks, and sorry for my English again.

Re: [Firebird-net-provider] Cannot attach to services manager service [host]:service_mgr is not defined
Hola Carlos, si ese gsec se ejecuta en las mismas condiciones que mi fbSecurity.DisplayUser(nombre) pero el resultado del gsec es exitoso mientras que el del DisplayUser da el error antes mencionado. Hay un router (con ip dinámico 200.127.218.24) que redirige el puerto 3050 a una máquina de la red local. Todas las pruebas realizadas desde la red local (sin pasar por el router) son exitosas, mientras que si las realizo desde otra red (contra el ip del router) el gsec funciona y el DisplayUser no. En pruebas anteriores la conexion remota a traves del router usando FbConnection me funciono sin problemas. Estaba pensando, FBsecurity utiliza otro puerto o algo asi?

Huummm asumo q ese gsec se esta ejecutando desde una maquina q no es el servidor al q realmente quieres acceder ;) Puedes establecer una conexion remota contra el servidor usando FbConnection ?? Estas seguro de q no hay un firewall bloqueando la conexion ??
