What to open first, data module or form

[Marsheng]

In the past I have opened the data module first to ensure all the tables etc are open before the forms.

I'm now opening sql tables via the net and I need to load data (username, location etc) before I open the tables. I want to store that data in a config.ini file and read this when my apps opens, however, the DM has no memos or edit boxes for me to loadfromfile into ?

Any suggsetions on how to solve the issue - you may have a completely different way of solving this problem.

If your problem is reading/writing to ini files then see http://www.swissdelphicenter.ch/en/showcode.php?id=160

Same issue - connecting to the DB but another angle.

I have a login page - I read the ini file and pre-populate the edit boxes.

If I put the TMyConnection on the login page, the datamodule components can't find the tables, even if I add the fLogin to the uses list.

If I put the TMyConnection on the DM page and the call fLogin with the on create, I get an access violation message. I assume it is because the DM has not fully created itself and the components.

Any Suggestions ?

I guess having a window on the DM form would be the answer.
