I have a really odd problem with some Visual Basic .NET 2003 code;
I have a program that creates a number of windows which contain
RichTextBox, Timers (disabled) and menus. The code runs fine and

generates an exception error (Object reference not set to instance of
an object - this always coincides...

Hello,
The following code generates an exception error the *second* time it is
called.
Can anyone see what I'm doing wrong?
There is a similar example in Wrox Professional VB.NET Page 289.
Error:
An unhandled exception of type 'System.ObjectDisposedException'
occurred in mscorlib.dll

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
