This only removes the image, but the object is still allocated in memory (isInitialized true) Code: Copy ImageView1.RemoveNodeFromParent Last edited: Nov 23, 2018

ThRuST Well-Known Member Licensed User Longtime User Nov 23, 2018 #9 Well, I suspected it but I didn't want to make you feel sorry you made a misstake, but it was good we sorted this out. I was convinced that you knew I was asking about B4J, so this answer is specific for that. Anyway, I checked isInitialized and it says true so I am not sure you understood my headline. It's one thing to have the image removed, but the object instance seems to be still active. I guess the old BASIC command ReDim will tell you what I mean. So now when we know how to clear image data we should successfully UNLOAD the object. Anyone? Upvote 0

ThRuST Well-Known Member Licensed User Longtime User Nov 23, 2018 #10 Something like Code: Copy ImageView1.Close so there must be a way to unload each of the controls that is initialized, right? Upvote 0
