I've been wondering how do you access the windows API?
[DllImport("user32.dll")]
public static extern int MessageBoxA(int h, string m, string c, int type);
and i'd calll that normally MessageBoxA(handler, "bla bla", "bla bla",
null);

Those should get you started. There's a lot of good content on

Don't forget to import your import module and to give the import library name for a linker If you have any further questions, please search the newsgroup. They have been answered at least 20 times! You also better see the C++ Compiler and Tools guide. -eye

Thank you, but a tutorial would be nice, it doesn't seem as easy as the .net way.

mono will succeed. D is still under development and yes I'm aware how
things are done in other languages, but attributes can really do cool
stuff. Wouldn't it be cool to have [DllImport] in D to save you from all
that coding? I'd really love for all the D developers to stop working on
individual libs and create a Delphi/.NET like library for D. Where is
LoadLibrary()?
dllImport("foobar.dll"):
{
extern(Windows):
{
int func(int i);
int func2(int foo);
}
}
do you have any idea how much code that would save?
[DllImport("user32.dll")]
public static extern int MessageBoxA(int h, string m, string c, int type);
[DllImport("user32.dll", EntryPoint="Foobar")]
public static extern int MyName(foo bar);
languages and ways to do things
and took only the good parts. It would be cool to extend attributes like
that in D.
If i wanted to extend that i would do
public class MyDllImportAttribute : DllImportAttribute
{
// extend it....
}
I guess i want a native/mutlti-platform .NET, mono will always be 2 years
behind microsoft and can always be shut down by ms. So yeah, i'd like D
to move very close to the way things are done in the .NET world and the
Delphi world.
Some people are doing xml work, others are doing other crap, move it all
together
system.xml module
system.windows.forms (for gui) even though i want namespaces
system.interop.

I have to correct myself: if a DLL uses Windows calling convention (they normally should!) it should be extern(windows) instead! -eye Ilya Minkov wrote:SpookyET wrote:how do i import a C dll and access it?Just like you do it in C or C++. - create a import file with extern(C) instead of a header - create an import library for a DLL using implib - go ahead and use it!
