I have some code that I would like to move from a form unit to an
ordinary unit as the form unit is getting too long. The form is created
at runtime:
frmWizard := TfrmWizard.Create(nil)
frmWizard is a variable that I have declared in a unit that is used by
all other units. frmWizard is displayed correctly, no problem so far.
Now the code that I would like to move references frmWizard:
with sli, frmWizard do //sli is a TStringList, declared earlier
begin
Clear; //clear sli
Add('some text');
Add(edb1.Text); //add edb1.Text to sli <-- exception here
Add(edb2.Text);
end;
This code works fine from within frmWizards's form unit (of course
without the reference to frmWizard in the with ... do). However, it
throws an exception if I move it. I've added a watch and for some reason
it tells me frmWizard is nil but I don't know why. The frmWizard unit is
referenced from the other unit as is the unit that declares frmWizard,
so I thought that shouldn't be the problem but apparently it's not
enough???
It's got to be something really simple but I just can't see it.
Any pointers gratefully received.
TIA.
