Hi There,

for a larger project I have set up some base-classes but I am coming to the point

where I don't know what to do.

I have build a base form class (mystdFRM) which is a strataframeform with some additional properties and a themed panel.

From this class I build a new class (mysingledatafrm) which has some methods for datahandling and a themed toolstrip with three buttons added (Save,Undo,Exit).

I use this form for simple data-entry like parameter setup or editing data based on a single BO.

So far everything works fine, but what I can't accomplish is to change controls derived from my base-class. For example, if I would like to add a fourth button to a form derived from mysingledatafrm (the one with the toolstrip on it), I can not modify the control, something I could do in VFP.

I found some articles explaining that I should change the modifiers of these controls to "protected friend" but this does not help.

Can anybody tell me, how or if this can be done (VB.NET/VS2010?

Thanks in advance

Thomas

Hi Thomas,

I have not tried with the ToolStrip since I don't use the maintenance ToolStrip, I basically follow the logic used in the StrataFlix sample using ActionLinkItems instead since I do have more control over those.

I do remember that once, when I was learning to use SF, I tried to add buttons to the SF toolstrip but couldn't do it and what I did was to hide the buttons I didn't use and add another toolstrip with the buttons I wanted, after that the StrataFlix sample came out and I choose to follow that logic in my designs.
