Hello,
My c# based windows service takes a while to dispose. I have to release
bunch of resources all over the place and unfortunately it can take
20-40 seconds before I can cleanly exit.
Every now and then, when I stop the service from the Services applet, it
will timeout and bring up an error message saying that the service isn't
responding.

Hi all,
I'm having trouble PInvoking a TCHAR within a struct.
I'll paste the specific struct's API definition below.
I've tried so many numerous variations.
The main Win32 error I get is 0x3f0 / 515L which amounts to ERROR_NO_TOKEN.
Every single instance of this in the past was due to mistakes I made while
within PInvoked structs.
Is anybody able to point me to documentation or just tell me outright how to

I would really appreciate it if someone could help me figure out what
I'm doing wrong trying to PInvoke SetupDiEnumDriverInfo. All the
other PInvokes i've done up to this point work fine. Whenver I
PInvoke SetupDiEnumDriverInfo though, I get winerror.h code of 1784L,
which basically says it doesn't like my buffer, which I assume is the
structure.
Below is my PInvoke, my structure and a sample of my code. Please,
please PLEASE help me!

A couple of days ago I was debating about whether to use C++/CLI or C#
2005's PInvoke in order to tie in my VS 2005 app with a legacy
csta32.dll file. So far I have tried to call one method out of the
csta32.dll and wind up with the PInvoke stack imbalance error. Here
are the data types my C# mappings are based on:
typedef unsigned long ACSHandle_t;
typedef enum {
APP_GEN_ID, /* application will provide invokeIDs; any 4-byte value

I need to use an unmanaged c++ dll which uses structs that contain callbacks and also functions. I have included the appropriate c++ definitials and my c# translations below.
I first defined the parameters as c# structs, but when I tried the call (to RtcInitialize) I got the following error:
MarshalDirectiveException
Method's type signature is not PInvoke compatible.
I then changed the structs to classes but now I get the following...

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 am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
