[DUG] Windows 7

[Bob Pawley]

Hi John

I set up the data aware components and datasets in a trial project and everything worked fine.

I then created a second datamodule (DM2) within the original project and copied the dataset and table to it, then connected the data aware components from the main form..

This worked well. So I am now pretty certain it has something to do with the datamodule form itself (DM1).

You suggested settings not being loaded at the correct time. I would appreciate some idea of how to check this out. 

I could just rebuild the project on DM2, however that's no guarantee that it won't happen again.

The ini file itself seems ok - at least to me.

I have D2007 on Windows 7, as far as I know I haven't used a Data module on yet.   However I have used a data module in a project running inside a VMWare XP virtual PC on the Windows 7 box definitely with no problem accessing databases.   I do recall that the 'Database Not Set'  might be caused by some settings (loaded from an ini file) not yet being in place when the Form Create runs, so you might want to make sure this is not what is behind it.   I had similar problems which were due to that.

If you are still stuck let me know, I could try a quick project - but I have D2007 not 2006.

Hi

I've just installed my BDS 2006 based project on Windows 7.

I have data aware components on a form communicating with datasets and tables on a Data Module Form (DM1).

I have no problem when the database is empty. I can compile the project, enter information into the databases and close the project and the information is distributed properly.

However, when I attempt to re-open the project (with the database containing information) it gives me a 'database not set' error and fails to compile.

When I move the dataset and table to the component form and reconnect them to the components on the same form, the project compiles and I can add and delete information and re-compile with no problem.

It seems that the problem may lay in a communication problem from the DM1 to the components.

Is this possible??

Bob
