My form has several numeric up down controls. All of these controls, when changed, call the same method:

Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured.

For our project, we've written a WinForms UserControl for graphing.
We're seeing some strange behavior when our control is sited in a TabControl - our control continuously fires Paint events, even when there is absolutely no activity by the user.
We only see this in the TabControl. When we site…

Hello,
I have a problem with modality of the forms under C#.NET. Let's say I have main form #0 (see the image below). This form represents main application form, where user can perform various operations. However, from time to time, there is a need to open additional non-modal form to perform additional…
