Hi all!
I have problems when writting bitmap to a byte array and after reading it
back form byte to Bitmap object.
What I do is this: First I throw Bitmap to a memory-stream and then I write

reading from byte over a memory-stream back to the Bitmap object.
Please help, I'm really stuck here!
Here's the code I use (Sorry for a long...

Hey,
I am just wondering if anyone has got any idea of setting up a new class
so that you could just print like the old ways with the printer class,
since I am writing a program that really requires simple black and white
text printing, but there is alot to print and it's needed at various
places, which is why I find that the new printing style with the
printdocument a bit too clumsy.
Any help would be appreciated.

The following sends my email, but the attachment is empty. The attachment
should contain the data that is in the string that was created from the
xmlReader.
I have a stored procedure written using For XML explicit, and it returns an
xml reader. Then the following:
xmlRdr.MoveToContent();
string myTemp = xmlRdr.ReadOuterXml();

Hi,
I use the RichTextBox in my program.
It will use different language in this RichTextBox (chinese and english
characters), and it set the "DualFont" and use different fonts.
By the way, how can I print out this content to printer easily?
Thanks!

I was running into the System.Drawing.Image.FromStream "parameter is
not valid" on some of the images I was retrieving from a blob column in
Sql Server. I thought there were corrupt images as almost all worked
(all are gifs), and only a few broke when this line ran: Image img =
Image.FromStream(ms); here is the original code:
b = (byte)dt.Rows.ItemArray;
//b.ToString()
ms = new MemoryStream();
ms.Write(b, 0, b.Length);

Hello,
I am a newbie in CSharp.
In C++ if we want to read from socket into the struct object we
directly type cast it as
recv(socketid,(char*),&struct_object,sizeof(struct object))
But C Sharp does not allow such thing.

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:

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,...
