I am writing a VB.NET application in Visual Studio 2003. I have written a
method that handles several events, such as closing a form and changing the
visible status of a form. I have some code that applies to all these
events, but I need to have specific code execute when the form closes. The
properties for this method are sender (the originator) and e (event
arguments). I know how to get typeof (sender) to determine what form or...

I have two forms, a menu and a data entry form. The entry form is bound
to a query against linked SQL server tables. In the deactivate event, I
have some code which asks the user if they want to save their changes and
they can respond with yes, no or cancel. If they press cancel, the entry
form stays active with the changes still entered.
So, if I'm on the entry form and have entered data, and then click on the
menu, the deactivate event...

I have a question on event handling. Here is my situation.
I have a main form which has a TreeView control containing nodes whose tags
contain class instances of test cases. As I traverse through the list of
nodes executing these tests one of the tests needs to fire an event. I need
that event to be picked up by the main form for it to do a desired action.
Now for the confusing part (to me). Sometimes that test case which fires

Hi,
I noticed an interesting effect when working with controls that are
dynamically loaded. For instance, on a web form with a PlaceHolder control
named ImageHolder, I dynamically add an image button at runtime:
//----- Code snippet
protected System.Web.UI.WebControls.PlaceHolder ImageHolder;
private void Page_Load(object sender, System.EventArgs e)

I am experiencing some strange behavior between a UserControl's validating event and a treeview control. Initially, I thought it was related to an issue in the Knowledgebase article 810852 (http://support.microsoft.com/kb/810852), but then I realized that the hotfix mentioned was in .Net v1.1, which I am using.
I took the sample from that article and recreated the situation I see in my application. (Code included below.)

The following code will display a tif file on a form. When another form is
moved over the tif image, the tif image is erased where the form was moved.
A paint event occurs when this happens. My question is..how would I save the
tif images as soon as it is initially painted, and then restore the image in
a paint event. It seems to me that there should be some sort of a SaveImage
method and a RestoreImage method that would be fast. Note:...

Hello,
I want to understand teh benefits of ajax technology. Does anyone has a good
website where AJAX EXTENSIONS is worked out so I really understand it.
There a 2 main questions:
1) How about the form load event. Why should it fire when I put a button in
a update panel? Is this necessary and is only the other controls related to
the update panel send back? Or the whole page (If this is true I really do
not get it). But please answer...

I have a .NET 2.0 MDI application where the child form has a Tab
Control. Each of the Tab in the Tab Control has a Validating event to
handle what it should do when the user changes tabs.
But these Validating Events are also fired when either the child form
or the main (parent) form Close icon is clicked. And I need for these
events to know if they are being invoked because the app (or child
window) is being closed. I have set a boolean...

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.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
