Hi,
if I drag an Outlook.MailItem to a Windows-Explorer window a
<subject>.msg file will be created.
Now I try to drag & drop a mail item to my own WinForm app.
Unfortunately it doesn't work. In the "drop event" are eight
DataFormats (e.Data.GetFormats()) but the important one (imho)
"FileContents" is "Nothing"/"null".

I am trying to implement the user feedback provided by
Windows Explorer when draggng a filename from one place to
another.
I have the drag and drop action worked out but have had no
luck in finding how to capture the piece of the screen
into a bitmap to simulate the movement. I know this could
be done with the Windows API but can't find any way to do
it with .Net functions.
Any help is appreciated.

I need to add the ability to drag from a Windows Form and drop into a
non dotNet application. For example, having a generated image in my
app that I wish to drag out into explorer as a friendly way to save
it.
I have tried creating the object that I place into the DoDragDrop() by
inheriting the COM interfaces IDropSource and IDataObject with no
luck. If anyone can help I am very much open to suggestions.
Thanks in advance!

Apologies for the ambiguous title, you will be expecting me to be asking how
to perform drag and drop from my application into another application.
Well, kind-of. I've got drag and drop sorted, apart from one thing. I'm
dragging and dropping items from my treeview and listview which represent
database "Images" (blobs). Now, I don't store the blob in the tree, I fetch
it when I need it. This is a problem for drag and drop, because, for...

I've implemented an IDataObject interface around one of my classes in order
to facilitate drag/drop from my application into explorer. What I want to
do is allow the user to select a series of data objects in my application
and to drag/drop them onto explorer for explorer to create files of them.
Is this possible, or will I just have to stick with an explicit "Export"
method in my program?

Hi all,
I hope somebody can help me with following problem:
I have an application where I can drag&drop files/dirs from within explorer
onto my form.
If multiple files/dirs are selected I can see that the order I get in my
drop event is not always the same as displayed in the explorer window.
Further more the order changes depending on how many files/dirs are

Hi All,
I'm trying to show a context menu during a drag drop operation similar
to the windows explorers right click drag and drop behavior (A full
working sample is at the end of the post):
void treeView1_DragDrop(object sender, DragEventArgs e)

ContextMenu mnu = new ContextMenu();
mnu.MenuItems.Add("Click me", OnCmClick);

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,...
