Hi,
I'm developing an app that uses a RichTextBox, and populates it with
colour formatted text at Form Load. However, I randomly receive this
error, which I believe is related to this data population:
Unhandled Exception: System.NullRefe renceException: Object reference
not set to an instance of an object.

Does anyone have any insight into this? I've googled to no avail so
far.
TIA

I am getting an unhandled system exception while writing to a RichTextBox. The process may run for a few hours or days before the error is generated
The message is "Cannot access a disposed object named RICHTEXTBOX." A check of the stack trace indicates the error is from the DLL that controls writing to the RTB. The form has not been closed and the line of code referenced is in a catch block that writes any error to this form's RTB (named...

Greetings!
I'm trying to make my ASPX page able to process WORD format document. I
learned that RichTextBox might help me, but I can't use it either by adding
it to my Web Control list or by writing "<asp:RichTextBox id="c1" />" in the
ASPX file. The error message shows "Cannot find RichTextBox in the
namespace of web controls" (something like that). Is there any way to add
RichTextBox in ASPX file? Or where can I find a substitute?...

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!

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,...
