Hello,
When I create a dll project using Dev-C++ it creates a function like the one below:
DLLIMPORT void HelloWorld ()
{
MessageBox (0, "Hello World from DLL!\n", "Hi", MB_ICONINFORMATION);
}
From my understanding off dllimport, it should be used for externally created
functions. Is there any reason why Dev-C++ creates such a function? What is

I am extremely frustrated. I am building c# application
for a call center and am using a third party API to access
some hardware. When develop and test my class using the
windows console the application runs flawlessly, but once
I call the class from inside a c# windows application the
program freezes, crashes etc...
there must be a way to make this work inside a windows app
as it run great as a command line app.

Hi,
I had a question on DllImport. On importing a function from a VC++ dll
using DllImport (to a C# program), the function argument data types
and the return types may be of a type that is not supported by C#. In
this case if I am not mistaken the system performs default marshalling
- matching the data types to its most similar equivalent in C#. Is
this right?
Also, I presume this can be overridden by using MarshalAs. Is this

I'm trying to make a sort of conditional compilation in my C# code because
my app is intended to run on both a Pocket PC and on a normal desktop PC. My
code uses a call to an API function that on the PPC is located in
coredll.dll and on the desktop in kernel32.dll. I could make two versions of
the DllImported funktions but then I would have to ask for the OS version in
every call to the function. This however causes the code to look messy...

I'm calling an unmanaged C++ DLL from C# using . When the

Hello,
is it possible to use DllImport to call a DLL in ASP.NET ?
Or is it necessarry that my DLL has to be copied into \System32 ?
My DLL is a native C++ 7.1 DLL (not managed, no COM, no regsvr32) and uses
Assembler to make some math in SSE.
The result is given out as an Int.
Using a C# console app (code below) it work fine & fast.

(Using VS2005 C# and compact Framework. Target device is running CE5).
I am creating a simple visual control (New Control Library project for smart
device Windows CE 5), derived from Label, with a couple of extra properties.
I need to call an external dll from this control, on a timer.
When I insert the declaration for the external dll function and build the
control project, strange things happen to any project that uses this
control.

Hi,
I have a C exported function in a DLL that has the following proto-type:
int _cdecl MyFunction( LPCSTR fmt, ... );
Does anyone know the DllImport declaration for this so that I can call this
in C#?
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,...
