Whereas loading tiffs and pngs from file into an Image WebControl work, the
images aren't shown when loaded from streams:
In a WebForm, the image's property "ImageUrl" is set to a handler, and this
handler gets the image from a database.
Please check the various image formats. (The images are stored in a SQL
database as Image type.)
I post you a demo HTTP handler below.
I guess, it's the ViewState which messes up (in Windows Forms I...

Hello -
I have images saved in my SQL SERVER 2000 database. Using ASP.NET (C#) is
there any way to temporarily save an image to a session object, and after
running some other operations, later retrieve the image from the session
object, convert it back to an image, and re-save it to the database?
Thanks?

I am using Cryptography. You can encrypt or decrypt by providing an
output stream as a parameter to the CryptoStream constructor. But I
need byte arrays, as I am encrypting on the fly to a socket, and need
to manage all socket traffic.
My thought was a stateful call to my own Encrypt and Decrypt routines.
That I would pass a MemoryStream to the CryptoStream constructor. But
it appears that for each write CryptoStream does to my memory...

Hi,
I'm converting a database application from Access 97 to C#/SQL Server. Old
database contains some images in OLE fields. I've figured out that there's
OLE header preceeding actual image data and dealt with some of the images
which were in standard BMP format but most of the images are in some other
format which is displayed ok in access application and can be copy/pasted to
any image editor but when doubleclicking it doesn't open any...

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...

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,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
