Linking against a Win32-DLL

[Marc Müller]

Hello,

as my first Project in D I am going to write a Application for my Wacom 
graphic tablet.

So i have to use a windows dll(wintab32.dll) - but i don't have a 
corresponding lib-file.

I have converted the C-Header I found with the dev-kit of my graphic 
tablet and converted it to D.

I tried to use the "export(C)" or the "export(Windows)" settings in the 
converted header file.

Example from the converted header -> wintab.d:
extern(Windows)
{
	UINT  WTInfoA(UINT , UINT , LPVOID );
}



demo.d:
import std.stdio;
import wintab;

void main(char[][] args)
{
	writefln("Hello World\n");
	WTInfo( 0, 0, null);
}



When i compile my Hello-World Application which is calling a function 
from the DLL i get the following errormessages from the compiler (using 
"extern (C)"):


dmd.exe demo.d -LC:/WINDOWS/system32/wintab32.dll
d:\Projects\wacom\dmd\bin\..\..\dm\bin\link.exe 
demo,,,user32+kernel32/noiC:/WINDOWS/system32/wintab32.dll;

demo.obj(demo)
  Error 42: Symbol Undefined _WTInfoA at 12



With "extern(Windows)" the last line reads:
  Error 42: Symbol Undefined _WTInfoA


I don't know what to do - and I can not find usefull information for 
using Win32-DLLs without a lib-file.
Are my compile settings correct?
Is the converted header correct?
Or is it just not possible using a DLL without a library?

Please give me a hint

Thanks
