Vanishing Declarationsdiscussion on it. Perhaps I don't know the right words to search for. This has happened occasionally for as long as I have been using VB.net, but at the moment, I can't fix it any more: For no apparent reason, all of a sudden, a windows form, which has been working fine all along, will suddenly generate an error "XYZ is not a member of myForm" Now I look at the code, and there, in the declarations section of the form is the line of code: Private WithEvents XYZ as SomeControl Looks like it is properly declared to me!!! The fix had always been to delete this line of code and re-enter it. Poof - all errors go away, everything is fine. TODAY I CAN NO LONGER FIX IT. The reason? As soon as I retype the line for XYZ, a DIFFERENT item pops up as not being a member of a form. 'ABC is not a member of SomeForm" I re-enter the line: Private WithEvents ABC as SomeControl and the ABC error goes away but the XYZ error returns! This is worse than DLL Hell. Has anyone seen this happen? It also happens where Implementations are not 'seen' any more. I will have at the top of the form, Implements Ixyz and the next line might be: Sub foo () Implements Ixyz.abc Yet the task list shows: SomeForm must implemnt Sub abc for interface Ixyz! I'm really stuck here today. This is version 1.1. Zorpiedoman wrote:

I did a byval when it should have been byref. Program still ran but gave me really screwy errors like you have. Try deleting your obj file and then recompiling. Chris No, no API calls.
However, if I shut down the IDE, re-open it and do NOT attempt to recomile and just run, sometimes it works. It's still very flaky. I'll try deleteing the obj files as you suggest, and see if it helps. I hope that 2.0 gets rid of this behavior. Still looking for more feedback if anyone has any. -- --Zorpie I seem to have similar behaviour with a somewhat large "solution" that I
am working with. Like you, I have attributed it to an IDE bug. I seem to have noticed a correlation with editing a class that contains a delegate declaration. When I try to run after editing this class I sometimes get a message that there were build errors in an unchanged form belonging to another project. The message is always about an undeclared symbol that is always an existing control on a form. It is not always the same control or form. I have found that simply doing a "Rebuild Solution" removes the problem, but this is a definite nuisance as I have a large number of projects in my solution and the rebuild can take significant time. I don't see this problem with other classes in the solution, and this is the only one that contains a delegate declaration, so I suspect it may have something to do with that. But I haven't had the opportunity to investigate further, so if you find a solution I'd be very interested.

I use delegates in every form that
causes this problem. The rebuild SOMETIMES works, but lately (and the reason for this posting) is that fixing one was creating anothier, and fixing the other recreated the first one so I was stuck in a loop. My current work around is to shut down the IDE, restart, (no errors come up) and RUN it immediately without a rebuild. Definetly a bugaboo. I'm upgrading to 2.0 this week, so hopefuly this will go away. (And be replaced by more inexplicable behavior, of course! :-)) -zorpie Show quoteHide quote > I don't see this problem with other classes in the solution, and this is > the only one that contains a delegate declaration, so I suspect it may > have something to do with that.

No guarantees, but if it solves your problem, it is at worst a minor irritant.
