I'm integrating my system with the database. SEFIP .
The database is in Interbase (.gbd).
I can make the connection to the database via Microsoft Access normally. I created an ODBC connection manually (Run: odbcad32 or Administrative Tools -> ODBC Data Sources) and I can connect to my system using the OdbcConnection .
OdbcConnection OdbcConn = new OdbcConnection("DSN=Sefip");
OdbcConn.Open();
In this way I perform the queries normally. The problem is that I will use this integration on many clients, so it is impractical to create the ODBC connection manually at all. To avoid doing this, I'm trying to create the connection through the system. This answer shows one way to do this, but the user and password are not passed to the connection.
This part was to fill in all the data. Although the data is in their respective variables, it is not saved in the DNS.
var dsnKey = Registry.LocalMachine.CreateSubKey(ODBC_INI_REG_PATH + dsnName);
if (dsnKey == null) throw new Exception("ODBC Registry key for DSN was not created");
dsnKey.SetValue("Database", database);
dsnKey.SetValue("Description", description);
dsnKey.SetValue("Driver", driverPath);
dsnKey.SetValue("LastUser", Environment.UserName);
dsnKey.SetValue("Server", server);
dsnKey.SetValue("Trusted_Connection", trustedConnection ? "Yes" : "No");
The complete code can be seen below:
private const string ODBC_INI_REG_PATH = "SOFTWARE\ODBC\ODBC.INI\";
private const string ODBCINST_INI_REG_PATH = "SOFTWARE\ODBC\ODBCINST.INI\";

datasourcesKey.SetValue(dsnName, driverName);
// Create new key in odbc.ini with dsn name and add values

When creating manually, these are the data in a working connection:
Whencreatedbythesystemtherestofthedataisempty,likethis: 
Mydoubtsare:Istheresomethingwrongwiththecodetonotpopulatetheconnectiondata,eventhevaluesbeingSetValue?IsthereanyproviderforEntityFrameworkorDappertomakethisconnection?
IsthereanywaytogettheconnectionstringofnewOdbcConnection("DSN=Sefip"); so I can use it in FbConnection () ?
For those who do not know, this tutorial explains how to set up source ODBC data manually.
