NT4 Informix

We develop our applications on the SCO/Unix and we would like to port to Windows. Recently we installed Informix workgroup server, informix-connection and informix-cli on window NT4 but we have trouble to understand all the enviornment setups and informix functionalities. I believe that I am going to ask you some stupid questions and I will be very appreciative if you can help me. (1) After installation, we created a database using the command, c:\\informix\\bin\\dbaccess this created a database named "test" on our informix NT server, test@acustafNT but I could not find where is the file located in my computer. Where is it? (I can locate the "test" database by using Database Explorer.) (2) How to use ILogin Demo for INFORMIX-ESQL/C? I have Database SQLcode=-25556 after I entered Server: acustafNT Hostname: MyComputerHost Servicename: turbo Protocolname: tcp-ip and StoresDatabase: test for connection. where is the possible error? (3) I installed ODBC driver for INFORMIX-CLI 2.5(32 bit) from ControlPanel/ODBC32 and I entered, test for Data Source Name, test for Database Name, Service name with turbo, Server Name with acustafNT. I would like to execute a SQL statement from C++ through ODBC connections. Could you please tell me how to do this by using Microsoft Visual C++? Will the DAO classes work with Informix? Could you please forward me an example to connect Informix using ODBC and execute a SQL query in Windows? (4) I tried to import imformix tables from Microsoft Access through ODBC. I can see the Import Object tables of Informix. But I select the table, I got a message said "Couldn't find object 'table name'". Something went wrong in my informix installation? Thank you very much! Chengteh Lee clee@acustaf.com
