There doesn't seem to be any documentation on how to create and/or use an
instance of System::Drawing::Graphics. On-line MSDN talks about this class,
and says:
" The Graphics class provides methods for drawing objects to the display
device. A Graphics object is associated with a specific device context. "
Great. So how about explaining HOW to do this? Or perhaps a code example? Or
at least a CONSTRUCTOR (or some explanation on how to...

I'm doing something wrong. I made up a test app and put the ZIP file on my
website
http://home.surewest.net/galen/index.html under Downloads.
Basically I have a Panel that will get continuous updates and I don't want
any flicker. In the test app it sets up a mem map and sets it to Black.
When the Button is clicked it calls a routine that puts tick marks at top
and bottom. The tick marks do not show up.

I'm interested in learning C++. I'm not sure exactly what this means. I'm
currently a VB.NET/C#.NET programmer (both Windows Forms and ASP.NET). I am
totally clueless when it comes to C++. I've tried creating new projects and
even that is confusing. I'm unsure of the differences between MFC, ATL,
Win32, etc. etc. applications. I don't even know where to begin.
If I wanted to write a full screen application with some type of simple...

I have written a class (Windows Form) in Managed C++ that accepts an
array of image filenames and will display them sequentially. All images
will be the same size. I got it to work, but I know something is not
right because of the way I am using Application::DoEvents() (ref:

Hi, everyone. I ran into an UI freeze issue with threading and
simplied the problem down to the following sample code. The logic is
as follows:
1. The main UI thread creates a non-UI STA thread(m_MainThread).
2. Then the non-UI thread runs and creates derived winform and holds
a reference to the winform. NOTE: I don't call Application.Run()
because I don't need a message pump on this "hidden form" in my
application. I rely on the...

Please excuse the long post, but I have an issue and don;t know how to
describe it without describing the app.
I have an app that reads data fro the serial port and draws it on the
screen. I have a timer set up, and when the timer fires it either
calls Simulate_read_sensor() or read_sensor() depending on a
checkbox.
The simulate function does this
for (x = 0; x < 102; x ++)

Hello,
I am a C++ newbie. I developed a Win32 DLL that creates a number of threads,
which can throw exceptions. When an exception is thrown on a thread in Win32
DLL, I want to catch that exception on the main thread.
Is there any way to throw an exception on one thread and catch it on another
thread?
If #1 is not possible, is there a catch-all exception handler at the process

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...
