Hi
I am using Listview and inherited listview control overriding WndProc
& PreProcessMessage in ListView.
I need this to customize listview to display only the page the user
scrolls to. Since i am populating listview with more than 200,000
items. It is too slow and tried virtual listview. But that doesnot
allow me to add images in the listview. So now trying to list only the
page user scrolls to.

Hi
I did alot of research on this on the web and msdn and I couldn't find
anything.
I have a listview showing as a grid (table looking, with rows and columns
and no images at all, only text). I get the information to display on the
listview from the network and I add items often and stuff.
But more than adding items, what worries me is the step of modifying items.

Hi,
I have a windows application that uses the listview to display about 50
items in detailed view - 4 columns. The first column is static and other
columns will be updated in 100-1000ms - it looks awful when it's running -
flickering too much!!!
Anyone know how to solve this flickering problem? or how should I deal with
this issue? I see some other C++ app can display more than 100 items without
any flickering in such as speed. Can...

Thanks Jay for your response.
I tried your code and it still flickering a lot. To demonstrate it, you can
grab a listview, create 3 columns - name, value, timestamp, in form_load
event to add 50 items into that listview as Item1 - Item49, add a timer to
your windows form, set the timer interval to 100 ms, in the event handler,
add the code to update the value and timestamp
Random r = new Random();
listView1.BeginUpdate();

I was looking at the code on codeproject to solve my listview
flickering issue. All the references to functions in the rest of my
post refer to that code. It's available at
http://www.codeproject.com/cs/miscctrl/listviewff.asp?df=100&forumid=14314&select=1488858&msg=1488858
That code didn't solve my problem. I have a ListView (in Details mode)
with about 70 rows and 12 columns. It's a stock ticker kind of app.
When it first starts, each...

Hi all,
I have made a derived Listview which can accept the controls as
items in it. Controls that we are using are Buttons in each row and
implemented Grouping with the help of controls(label on panel) . Coz
Inbuilt listview Grouping not supported in OS like window 98.
Although I had used Double buffering
(SetStyle(ControlStyles.DoubleBuffer, true); .. in my Listview) but
still the listview flickers much when we scroll its items. ...

Hello, I'm trying to prevent a listView from repainting when I change group assignments for the items. Let's assume I have two groups with 100 items in each and moves 100 items from group A to group B, then the listView will repaint itself a lot, slowing down the operation and flickering (can be solved by listView.Visible = false; but it doesn't speed it up, i.e. the listView still repaints itself).
There are the listView.BeginUpdate() and...

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

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...
