As a newbie, I am puzzled as to how I am supposed to reference the VCL controls on a form from another unit.

When I add a new ADX Outlook form to my project, the unit includes the note that The adxOlForm1 variable is intended for the exclusive use by the TadxOlFormsCollectionItem Designer. NEVER use this variable for other purposes.

So how am I supposed to reference the form / controls from, say, the AddInModule? Normally, I would write something like:-

with adxOlForm1 do
begin

end;

but this appears to be the wrong way to do it!

Hello Andrew,

That variable must be used by the designer exclusively. In fact, you don't deal with the form, you deal with instances of the form that the forms manager creates (when required). As to how to access a form instance, please see section Form Region Instancing in the PDF file in the folder {Add-in Express}\Docs on your development PC.
