I am trying to use reflection to add an event handler for the RowUpdated
event of the OracleDataAdapter object (ODP.NET), but the same thing can be
said for SqlDataAdapter if you only use reflection. The code I supplied is
based on the SqlDataAdapter with reflection.
The error occurs when trying to create the delegate that will be passed in
to EventInfo.AddEventHandler. I get the following error:

Is it good programming practice to call an event within an event?
I'm I creating recursion somehow somewhere? Does an event (e.g. send, e)
ever end?
I'm sorry, I'm not sure I know what I mean, however, I do know what ever it
is I should be aware of it.

All,
Thanks in advance for any help. I am attempting to write a property
that is an array of strings. I am trying to trap the event when one of
the strings in the array changes.
When I step through the code, I can walk through the Set statement when
the length of the array changes (and therefore trap anything I want),
but if one of the elements change, it does not go through the
statement. I am attempting to write my own control...

Is there any way in Mozilla/Firefox to add an event listener to all
textarea elements? Something along the lines of
HTMLTextAreaElement.prototype.onkeydown = function() {alert('mom');}
only it should work, too.
Or is my only solution to loop through each one and use
..addEventListener? And then trap for any DOM modifiactions in case new
ones are created.
Thanks,

Getting errors after following the MSDN article on using VB.NET (and VS2005)
for "Implementing a Managed OnSave Event Sink" for Exchange Server 2007. Not
sure, but part of the problem may be that it's the 64-bit version of
Exchange 2007 installed on Windows Server 2003 Enterprise x64, while the
Exchange 2007 SDK samples seem mostly geared toward 32-bit. Even at that, I
was able to build the TLB and install it into COM+ Component Services,...

I am trying to bind a WPF dependency property to an aggregate of a
collection. I've implemented a wrapper around a Dictionary that
implements INotifyCollectionChanged to fire the event when items are
added or removed.
Debugging through it I notice that there is nothing listening to the
event after I bind to it which I expected the SetBinding to do as I
don't know what delegate to attach to the event. It's the binding that
needs updating...

I am having trouble preventing a bound source from updating using event-driven validation.
There is a very nice article on MSDN explaining this;
http://msdn.microsoft.com/en-us/library/ms229603.aspx
It clearly states, "When you use data binding, the data in your control is synchronized with the data source during execution of the Validating event. If you cancel the Validating event, the data will not be synchronized with the data source."...

Overview:
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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
