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 All
I used listview and tried to update it by using Addrange.
When the number of items is less, it works fine.. But I
need to update nearly 200,000 items and it hangs. Also i
need to add images to listview also(This is to list all
the items in my inbox, and want to give the user the feel
of outlook).
Since it hangs for even 1000 items in the inbox, i tried
to shift to virtual listview. But virtual listview

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. ...

I'm trying to change the cursor that appears on a standard ListView when the cursor appears over an item. However I am getting a flickering effect as the mouse is changed to a finger cursor, and then back to what I asked it to be.
I'm trying to isolate this flicker/changing to the hand cursor but can't figure out where it's occuring or how to stop it. To replicate this...

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...

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,...
