It seems to me that the TAG property is a variant, so you can assign any kind of value to it (at least in code); using the GUI designer seems to let you only use strings. When you later access the TAG property, its value will retain the type of data you assigned to it. For example, I just tried this: PUBLIC SUB Form_Open() TextArea1.Tag = listview1 TextBox1.Text = TextArea1.Tag.name TextBox1.Text = TextArea1.Tag END The first line shows that you can assign an arbitrary object to the TAG field. The second line shows that you can read what is stored in TAG; having you stored a ListView, then you can read its Name property, The text of TextBox1 now gets assigned to the string "Listview1". The third line fires an error, but only at runtime; during compilation gambas can not know what the content of Textarea1.Tag is, so it can not decide if this content is compatible to a string (to be stored in TextBox1.text). At runtime, instead, gambas reads the content of TextArea1.tag and it finds it is an object: the object ListView1; now, it can not assign an object to a string, so it rises an errore (expected string, got ListView instead...). About "recover any kind [...] from into a loop", I don't understand. Perhaps you want to scan all the controls residing on a form - there is the Controls[] property for that. Or you want to stream out all the properties of an object, perhaps to a file? This is possible too, I think - look at the Object class (or the Class class, can't remember), which has method to inspect... objects. Regards, -- Doriano Blengino "Listen twice before you speak.
