Still struggling..

------------------------------
* Coffimplib was used to convert the d2d1.lib from Microsoft
DirectX SDK (June 2010). The converted d2d1.dll was placed in
C:\dcode\dlls
* With test.d in C:\dcode, the file was compiled and linked in
C:\dcode with:
dmd test.d %cd%\dlls\d2d1.lib -I%cd%\dlls\
-version=DXSDK_JUNE_2010
- Why is the method identifier undefined?
- Are there any code examples showing the right use of the
bindings?
