OpenFileDialog appears to be "holding onto" the parent folder of a
selected file until the application using the dialog quits.
After creating a folder containing a file, I attempted to select that
file with an OpenFileDialog. I used the following code to create the dialog:
Dim a As New OpenFileDialog
a.ShowDialog()
a.Dispose()
When the OpenFileDialog appears, navigate to the file within the folder
and click “Open”.
Leaving the application still running, attempt to delete the Folder
containing this file. On my machine, it fails with “Cannot delete
'myfoldername': It is being used by another person or program"...
Why is this? I haven’t attempted to actually open the file; merely
selected it. It appears as though the OpenFileDialog box is holding onto
the containing folder until the application is closed, afterwhich the
folder can be deleted. Disposing of the OpenFileDialog doesn’t seem to
help either. However, the actual selected file is not being locked--only
the parent folder.
Any ideas what might be causing this?

What does CurDir return after a.dispose? Have you tried setting
a.RestoreDirect ory = True before a.Showdialog? If it is False, the current
directory changes to the directory of the selected file, thus it can not be
deleted. It is not the OpenFileDialog that locks the directory, it's because
the process's current (working) directory has been changed.

If you can set the 'initial' path of an OpenFileDialog box by something like
the following:
Dim FilesPath As String ' Files Path
FilesPath = "P:\Projects\"
FilesPath = OpenFileDialog1.InitialDirectory
HOW can you set a 'current' path?

I've asked this question before but now I need something different: I need
to select files using openfiledialog, which is easy enough. But I want to
select a file or files (multiselect) and also single click select a folder
or folders (double click would open the folder, as the openfiledialog now
does).
I don't want to just browse the folder. For example, when I cut a cd using
Record Now, it can select both files and entire folders and...

Hello all,
I am using an openFileDialog box to select a file (in order to insert it in
a database). When the file is selected i am filling a few textboxes with the
actual path, filename and extension of the file, so i no longer need the
openfiledialog, thus i am using openfiledialog1.reset() method to reset it.
(i have also tried openfiledialog.dispose() with no results)
The problem i am encountering is that the folder in which the...

I'm a bit confused by this - when I set the InitialDiretory of an
OpenFileDialog to be a subfolder within the same folder as the app, the
file dialog does not initially display the folder - instead it shows
the last used folder (this persists after closing the app).
However, if I use a different path (e.g. "C:\\") then every time the
dialog is shown, it starts at the correct directory every time.
Is there something special about an...

Is there any way to hack OpenFileDialog (either in .NET 2.0 or in Win32)
that will allow the user to select a folder rather than a file? Better yet,
multiselect them.
I know about FolderBrowserDialog, but it's not satisfactory because it
doesn't show or follow shortcuts, and also because users are not as familiar
with it.

Hello,
I have written a windows service that runs under the LocalSystem

This service launches a GUI that contains several

When I log on as a user, interacts with the GUI and open a filedialog,

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.

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,...
