We're running Load Runner to test a large 1.0 based WinForms application.
I'm getting the following exception when opening and closing a form 400 -
450 times. The form contains several controls and custom UserControls. All
the code is native C#.
I'm not making an explicit call to ToBitmap or DrawIcon in my code. Can
anyone help?

It sounds like the form is not being disposed or disposed
in a timely enough manner. You may want to try
calling .Dispose on form_unload().
Just a thought. -----Original Message-----

I am (still) relatively new to Windows applications, most of my experience

Main() method is called and how to manipulate forms opening & closing.
An example of this issue is as follows. I have a logon form open as the
first thing. The main functional form opens when a user has successfully
logged on. From the main form, a user should be able to logout which will...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
