Category   :VCL
Platform    :All
Product    :C++Builder  1.x

Question:

Why am I getting Access Violation with this code on my
Form's constructor?

DataModule1->Table1->DisableControls();
DataModule1->Table2->DisableControls();

Answer:

Because the DataModule form doesn't exist yet.

Change the order of the forms automatically created on your
project at Options | Project | Forms by moving the DataModule
form to be first on the list.

You can also move the code to the OnActivate event handler
on the original form.
