Title: Using DataModules query
Post by: daveinhull on February 21, 2019, 02:29:32 am

Hi,

I've been working on a program and the number of non-visible objects has grown to a point that I thought I had bettr start using DataModules.
So I moved all the non-visible objects into a Data modules (DataModule1) and add the 'uses' reference to my main form.

I then went through and referenced all the uses with DataModule1. prefex (Know I should seperate the uses better between the main form and the datamodule, but for now I just wanted to try it this way), e.g. DataModule1.Connection1.Connected := True etc.

However, when I run the program, the references to DataModule1 are all zero and it crashes.

Have I forgot to do something, like initialise the the datamodule?

Thanks
Dave
