The documentation on dynamic handlers comes across as abiguous.
Perhaps somebody could help set me straight?
I have a situation where I need to dynamically create several
usercontrols of the same type within a form. This usercontrol has some
events associated with it.
For example:
Private Sub NewThingy()

Hi,
I was trying to store the address of the my current handler for a
particular event so as to simplify using AddHandler and RemoveHandler
throughout my code. However, I cannot seem to get any kind of variable
to except the data. When I tried a Long I got the message "'AddressOf'
expression cannot be converted to 'Long' because 'Long' is...

second cbo. The second cbo (cboView) selects the secondary table which
determine the dataAdapter used to fill the dataGrid. Both cbo's are
populated by filling dataAdapters.

Hello,
I can't figure out how to solve this problem. I modified the timer
example given in the help section. It increments a count every 3
millisecond in order to simulate a tank being filled with a pump rated
at 180 GPM. It works fine on the first pass but, when I select the
stop command and then restart it the incremented values are a...

I use dynamically created controls all the time. I.E. I create the
control in code then use AddHandler to add the necessary delegates for
processing (like Click, etc).
Does one have to call RemoveHandler after processing is done? In other
words, when the form is closing do I have to do a RemoveHandler for
each one of the controls I created?...

Hi, I think I understand why it behaves how it behaves.
A new feature of VB9 allows you to AddHandler for methods with slightly
different signatures than signature of event is. However as I understand it
some hidden routing method/delegate (which routes event to method with
different signature) is created in compile time. And when you uses...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
