Hi,
I need to update the last line of Lines in my derived RichTextBox.
Since I can't do this:
Lines = history as string;
I need to copy 'Lines' to a tmp array, change it and copy it back to
'Lines':

hi,
i'm trying to use the RichTextBoxSelectionColor property, but in any
combination of command order i try, the text color is not changed. the
only time it worked was when i set SelectionStart = 0.
here's one version i tried:
String res = "Failed";
int selectionStart = rtbTestResult.TextLength;
rtbTestResult.AppendText(res + Environment.NewLine);

The documentation for the RichTextBox is sketchy at best. I want to do a
very simple task but I cannot find information on this. I am using a
RichTextBox as an output window. Some text I want to just add plain (e.g..
rtf.Text += "new stuff..."; ) but some text, when added, I want to be in a
different color or font size. Find() will not work because the text will
vary. I have delimiters on it so I could recognize it with a regular ...

I have created a Control that extends RichTextBox to do syntax-hilighting. My
strategy is to have a timer that restarts every time a user types a key so
that it can wait until the user pauses for at least 500 milliseconds, then
perform its work. The hilighting simply goes through a list of keywords,
finding each instance in the RichTextBox, and selecting it in order to change
its color. I figured out how to remember where the cursor is and...

Hello,
I have a RichTextBox that has a large number of lines, well in excess of the amount that can be seen without scrolling. Upon an event, such as clicking a button, I would like to move the viewable portion of the RichTextBox to be able to see that particular line. In other words, if the RichTextBox has 1000 lines of text, how can I force the viewable portion to start at, say, line number 123?
This is what I have tried so far:

After a lot of debugging effort I have to conclude that it does. Or at
least can. I take a substring (RichTextBox.Text.Substring) before setting
SelectionStart and after and get a different result. The second result
begins two characters to the right of the first.
In an earlier version of the program I did not have this problem. But in
that version the RichTextBox actually appeared on a form. In the version of
the program with the...

Hello,
I have a multiline RichTextBox that I use for data logging. I'm concerned
about how the AppendText method reacts when over time the maximum number of
characters have been added. Do the oldest characters it contains start
rolling off the top into the bit bucket, does it simply start silently
ignoring appends until some characters, are deleted, or does some kind of
exception get thrown? I've heard numerous opinions on what the...

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...

Overview:
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,...

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.
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...
