I am trying to display images from an Access 2000 database and I get an error
"Invalid Parameter Used" when I execute the code line
"picBLOB.Image = Image.FromStream(stmBLOBData)" in my Visual Basic .Net
application.
I have researched MSDN for help and found the example article 321900 (see
below) and set up a test and everything works fine when I use SQL Server 2000
but when I modify the code and use data from Access 2000 using an...

I'm creating a custom control (inherited from UserControl) that is displayed
by other controls on the form. I would like for the control to disappear
when the user clicks outside my control the same way a menu does. To do
this my control needs to get notified when the user tried to click off of
it. The Leave and LostFocus events of the UserControl work most of the time
but not always. For example, if they click on a part of the form...

I'm afraid I will incur the wraith of Mr. Powell on this one - but I did read
his #1 FAQ and some others and I still can't figure this out.
I created this little c# app. and I have a PictureBox in my Form. I load
this image from the filesystem into the PictureBox and then I draw random
little lines on the image. Then when I minimize and reopen the application
the little lines are gone.
Is there a way to save my lines in memory and...

Dear All,
This may sound like an elementary question but how do you implement
scrollbars for the Picturebox control. Do I have to create my own code to do
this or is there some property that I can set? Thank you very much for your
time and consideration in this matter!

Dear All,
Recently I created a thread about trying to load a particular ICON image
that GDI plus could not load. I realized that GDI plus definitely does not
support it because it had a certain resolution that is not in any of its
built in format libraries. So my question is this, how would I go about
working with images that are not in GDI+ native libraries, such as raw
camera files (*.RAW, etc.), Pixar's file format, and plenty of other...

Coming from VB6 a PictureBox was a container for other controls. This
doesn't seem to be the case with .NET. In light of that can someone comment
on the following....
I'm creating an app that loads a Form to maximum screen size. On the Form I
have a PictureBox control that also maxs out to the screen's full
resolution. I then randomly load images into the PictureBox. What I was
hoping to do is have a Panel inside the PictureBox that...

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...
