Don't use this unless you already have a BDE Alias set up by this name and you would like to have the connection details picked up from an idapi32.cfg file.

That will happen automatically when you initially set up the server, protocol and path properties. It is a good idea to give this a "friendly" name. That will become a kind of alias in your application to represent the actual connection string, whatever that might be on the system where the app is installed.

It needs to be a physical path (not mapped, not UNC notation), e.g.


>2. TIB_Transaction has "IB_Connection" set to "Connect".

It might not be such a great idea to name objects with names of other members, i.e. Connect is also the name of a (rather essential) method. Change it to sthg else, e.g. "Connection"

Assuming all the pieces are properly connected to one another, you will need to do the following:

1. in the DPR file, move the Create call for the datamodule up above that for the form.

2. If you want the datasets to be open when you start the application, you will need to open them in the FormCreate of the datamodule, e.g.
ii: integer;
with myDatamodule do
if not Connection.connected then
// connect ib_queries
for ii := 0 to ComponentCount - 1 do
if Components[ii] is TIB_BDataset then
with Components[ii] as TIB_BDataset do
else if Components[ii] is TIB_Cursor do

This btw is just a generic way to go about it - if you have parameterised statements, datasets you don't want to open at FormCreate, etc., you will have to address each dataset more specifically.
