Hi all,

I have a windows forms project, under which i've built several
component classes, e.g. extended controls like combobox, textbox and so
forth...

For me to be able to drag and drop them on a form, i always need to
perform the following actions :

- On the Toolbox Panel, under Components tab, right click then
"Add/Remove items"
- Browse to my assembly... "projectname.exe"
- Pick up the components listed, added after the browse, from the .Net
Framework components tab
- Get them added to the toolbox where i'm then able to perform my drag
an drop action

The problem (if any...) is, sometimes, the components after they get
added, remain under the Toolbox panel for weeks and then disappear for
unknown reason to me, so i need to perform the same operation described
above everytime.

So, could anybody explain why this is happening ? Is it because, when
the component class gets modified, we must readd it again in the
toolbox in order to have the latest version ?

Is there any way to add the component so that it remains persistent in
the toolbox pane, unless we do a remove explicitly ?

Thanks for helping,
Mike
