vb.net - Why am I getting System.NullReferenceException: Object reference not set to an instance of an object? -

-

this question has answer here:

i'm trying assign instance of form form property

the system keeps showing error @ second line of code below

dim objfrm = new lsprog.sfile.frmtestrel(addressof sopdos, addressof sopdosline, addressof sopfac)  _favoriteform.frminstance = objfrm _favoriteform.frmname = objfrm.name

if nullreferenceexception need think null , go , make sure initialise it.

you told us

_favoriteform.frminstance = objfrm

threw exception, _favoriteform null , needs initialised fist.
