Question

I have developed a client/server application using a firebird db and Delphi XE2. The problem is that the TSQLConnection component on the client automatically sets the HostName propery to localhost. I would like to know, how can I write code that will give the user the option to set the HostName when the client starts the first time.

I placed the TSQLConnection component on a datamodule on the client.

On the main form, I placed an option for the user to set the HostName propery with the following code assigning the value that the user entered into the TextBox:

Database.SQLServer.Params.Add('HostName='+edtHostName.Text);

But it seems that once the program starts the TSQLConnection component sets the hostname to localhost and I cannot set it to the users Hostname. Can anyone please help me

Answer 1

The hostname is not a valid property for the dbexpress firebird connections, instead you must use the the DataBase property to specify the host using one of these formats.

1) specifing the port , host and database

  server_host/port:/path/to/database.fdb

2) specifing the host and database

  server_host:/path/to/database.fdb

3) specifing only the database

/path/to/database.fdb

So using DbExpress this will look like

  SQLConnection1.Params.Values['Database']:='192.168.1.125/3050:C:\Program Files (x86)\Firebird\Firebird_2_0\examples\empbuild\EMPLOYEE.FDB';
