Hi,
In an ASP.Net application I want to convert open create a FileStream
object from a System.Drawing.Image - is this possible? I create an instance
of an Image object using the FromFile method, then use the GetThumbnailImage
method to create a second Image. This second one is the one I want to get a
FileStream from, so that I can then use its Handle to use Response.WriteFile
to output the thumbnail on my ASP.Net page.
Any help would...

I have an interesting quandary.
I have developed a program in VB.Net to extract an icon resource from an
exe/dll or from an ico file and enumerate its formats (16x16,256
color;32x32,true color;etc.). It reads out the structures all the way down
to the ICONIMAGE structures. I have this represented as an array of bytes
read from the resource. I am using the unmanaged function
CreateIconFromResourceEx to generate an hIcon pointer. I take...

I have a Windows Form control that I have embedded in an ASP.NET page.
I now have the need to catch an event from the control on the webpage.
After researching the situation I found that this is the way to expose
events. I added the following code to my class.
Imports System.IO
Imports Assetta.ColumnStyles
Imports ICSharpCode.SharpZipLib.Zip.Compression
Imports ICSharpCode.SharpZipLib.Zip.Compression.Streams

Hello,
I had an earlier post regarding a strange exception I
(thought) I was getting in my windows form. I have since
been able to trace the problem to a picturebox control on
my form. I can reproduce the exception consistently, but
it seems to be timing dependent. Here is what happens:
I have a subform that I open, load an image from a file
into my PictureBox, take some user input, then I hide the

I am creating an imaging service using WIA (Windows Imaging
Acquisition).
The problem is that I cannot convert a WIA.ImageFile to a
System.Drawing.Image to put a timestamp on the image without first
saving the file using the wia.imagefile.savefile then loading it again
using System.Drawing.Image.FromFile. This seems pretty ineffecient. I
have tried coverting it using ctype, but I get an invalid cast
exception. Is anyone aware of how to...

I'm trying to use a Web Service to be a Remoting client of an existing
..NET 2.0 server. But I get the following error when I try to use
System.Runtime.Remoting.Channels.Http in my WebService. The same code
works fine in a standalone app. I have inspected
System.Runtime.Remoting.dll with ildasm, and I can see the
....Channels.Http namespace there. I verified that the virtual

I have this code that writes a pie chart in a asp.net page, but I want to
use it in a server control.
When I try I get a error on the last line "Response.OutputStream"
Obviously there is no response object but how do I write it to screen?

I am attempting to create icons for controls I have created using VB.NET by
using the System.Drawing.ToolboxBitmap attribute. I have managed to do this
in C# by specifying the path to the *.ico file, but I have been unable to
get any of the overloads to work in VB.NET. I would like to store the *.ico
files in a *.resx file so that users do not need anything other than the
*.dll, but at the moment I am just trying to get any of the overloads...

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:

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,...
