Cannot convert of type HANDLE to HANDLE

[Sam Hu]

Under DMD 2.032+Window Xp:

Can I use

HMODULE LoadLibraryEx(
  LPCTSTR lpFileName,  // file name of module
  HANDLE hFile,           // reserved, must be NULL
  DWORD dwFlags           // entry-point execution option
);

in D2?Given below code :

HMODULE hDll=LoadLibraryEx(toStringz("netmsg.dll"),null,        
DONT_RESOLVE_DLL_REFERENCES);
I got below error:
cannot implicitly convert expression 
(LoadLibraryExA(toStringz("netmsg.dll"),null,1u)) of type HANDLE to HANDLE

What's the problem?
Thanks for your help in advance.

Regards,
Sam
