Hello,

is it possible to access a TTable in my main application from a DLL that is
linked to the exe at runtime? I have some database structures in my EXE that
i want to access from several Plugins. Currently i have to put a lot TTables
on every Plugin and have to open the database multiple times.

I tried to use Sharemem and then transferred the TTable to the DLL via
function:

function StartPlugin(AContHandle:THandle; TPat1:TTable):THandle;

Within the DLL I try to access the table:
...
TPat.Assign(TPat1);
frmPlugin.Datasource1.Dataset:=TPat;
...

This always gives me an Access Violation, although Sharemem is included as
first unit in all DPR and PAS files.

Any help is VERY appreciated! I will pay $50 for the solution (=50 Euro or
100 DM)!
