• Visual Basic Adding 100 progress bars to a list view control

  Hi, I have a process that spawns 100 sub-processes. I need to display the progress of each of them. I was thinking about doing this using 100 progressbar controls contained in some other control.

• Windows Forms Doesn't beep when bound controls fail validation (bound to business object)

  I have business objects all inheriting from a base object class implementing INotifyPropertyChanged and IDataErrorInfo. This works well - the ErrorProvider control does it's job (flashes an icon with tooltip validation error message), the text boxes don't lose focus when they are invalid, and I am (almost) happy.... However, when a control's value is invalid the user is not able to tab out of the control (e.g. textbox) - which is perfect f ...Show All

• Visual Studio 2008 (Pre-release) IIS Hosting - WSHttpBinding problem.

  Hi, This question is related to a previous post that didn't get any answer yet : I have a service that is IIS-hosted.
