hi all,
I have a problem which I believe others have experienced before, but as far
as I can see has not been resolved.
Basically, the form refuses to close. Neither clicking the 'X' button nor
calling Form.Close works. The Closing event is not thrown. The form
contains a number of controls, some of which are derived from UserControl.
The problem can be reproduced by setting certain child control properties,
but they're pretty innocuous things like the title of a graph, so I can't
see how they'd have such an effect...
A few people seem to have come across this problem. Is it a bug known to
MS? (if anyone knows of a relevant KB article I'd be very grateful! I have
looked, but couldn't find anything)
cheers,
Rob

I would suggest this option like a last resource - it abrubtly exits.
Instead try pinpointing the source of problem.

Does your app use threads? Do you update the controls from the threads?

This is a well-known bug that was introduced in RC1 of the .NET
framework. Pretty much all of my WinForms applications have "workaround
code" to get around this bug. For some odd reason, Microsoft refuses to fix
this particular bug despite the fact that people have been complaining about
it for years. Here is more information + advice: http://www.jelovic.com/weblog/e41.htm
ever heard of it happening *without* manually removing controls? The code
I'm having trouble with has user controls on other user controls on tabs etc
etc, but they're never removed. Do you reckon adding & removing columns in
a datagrid could cause it?
I take it there's no KB article on MSDN, is there...?
cheers!

Yes. This happened to me when using the SoftwareFX charting component,
ChartFX. This chart object offers the user the ability to manually type
values into a grid which then updates the chart. At some point, I'm guessing
that the component instantiates a little text box for the user to use when
typing. When the user is done typing, that little text box is destroyed.
Although I can't be certain, I'm guessing that at some point during the
process, the charting component creates and destroys a UserControl-derived
object. Since the designer of the control wasn't aware of this ridiculous
Microsoft bug, and because the control doesn't provide me with any feedback
as to when the control is being removed, there is absolutely no way for me
to workaround this bug. If the user decides to use this particular feature
of the chart, the form window won't close and the user is forced to use an
abrupt "End Task" to manually kill the process of the WinForms app. In the
end, I chose to simply disable this particular feature in the chart rather
than trying to teach users to manually kill the process.
The fact that this problem hasn't been addressed after all of these years is
completely unacceptable.

ah hah! I'm using the ChartFX control too! Do you mind if I include your
post in a bug report I'm going to send to SoftwareFX?
I've found that the problem manifests after the user changes the graph
title, so I guess it's the little popup text edit box that's causing the
problem.

is completely unacceptable.
uh huh. I can't understand why MS would ignore a problem this bad.
> ah hah! I'm using the ChartFX control too! Do you mind if I include your post in a bug report I'm going to send to SoftwareFX?
Please do! That would be awesome if they added a workaround to their
component... This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
