We are using Visual Studio.NET 2003 in our project with .NET framework
1.1. One of our libraries is a mixed-mode dll assembly consisting of
one managed C++ library, and several unmanaged C++ libraries. We are
using managed C++ as a bridge between managed .NET code and unmanaged
C++ code, which I'm sure is a fairly common practice. The managed C++
library is compiled with /CLR whereas all other libraries are compiled
without /CLR because...

What is the difference between a managed/unmanaged resource, and how do you

methods, and we are supposed to put code that deals with managed in one
place, and code that deals with unmanaged in another place, but I can't seem
to find anything that clearly explains what that means.
I think if I used a Windows API function to optain a handle, that handle
would be an...

I've got a call within my .NET code to a function which uses an API call to
get printer settings. When there's an error in the API call code, it
crashes the .NET app. Try Catch doesn't prevent the crash - it's like it
crashes before the catch catches.....
Any ideas how to error handle this type of function so it doesn't crash the
application??
TIA

Hello, all,
I am currently working on a .Net (VB) application that invokes routines
in unmanaged (Fortran) DLLs. The unmanaged routines then communicate
with the .Net application by means of a call-back mechanism. These
calls pass a string that contains a "command" and a pointer to a
SafeArray that (depending on the command) either receives data from the
..Net application or provides data to the .Net application.
This mechanism is...

Hi All
I have a VC++ 2005 MFC application with all classes defined as

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,...
