Forms

[Guest]

I have a form which shows advanced options relative to the application I'm writing. I have two other forms which may need to call this form up

How can I set the 'advanced options' form so that it can be called up these two forms (and exposing the controls on the two forms as well)
How do I know at runtime which form made the call
How can I reference controls on the calling form? I may need to change text boxes or other properties of controls based on the options the user chose

Hope this makes some sort of sense
Thanks
Mar

Don't do this. Suggestion: Use the 'advanced options' Form only to
manipulate data like an object containing the options. You can pass the
Options object from one Form to the options Form. The Options class should
implement IClonable so you are able to modify a clone of the object and to
have a cancel button. When the Options Form returns, it can either return
the new Options object or the modified original object. If you immediatelly
want to reflect changes to the Options object in the calling form, you could
add "XYChanged" events to the Options object, handled by the calling form
immediatelly reflecting the changes.

That suggestion sounds like the best way to go. How then do I return the Options object back to the calling form, programmaticly speaking?

private m_Options as options

public shadows function ShowDialog( _
byval Options as options) _
as dialogresult

m_options = options.clone
'... fill controls with object properties here...

showdialog = mybase.showdialog
if showdialog = dialogresult.ok then
options.copycontent(m_options)
end if

end function

Call:
dim OptionsForm as new optionsform

if optionsform.showdialog(options) = ok then
'... reflect changes
end if
