3q JohnF,but why?
in shellapi.h:
typedef struct _SHFILEOPSTRUCTA {
HWND hwnd;
UINT wFunc;
LPCSTR pFrom;
LPCSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCSTR lpszProgressTitle;
} SHFILEOPSTRUCTA, *LPSHFILEOPSTRUCTA;
typedef struct _SHFILEOPSTRUCTW {
HWND hwnd;
UINT wFunc;
LPCWSTR pFrom;
LPCWSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCWSTR lpszProgressTitle;
} SHFILEOPSTRUCTW, *LPSHFILEOPSTRUCTW;
>but why
The compiler does not know the value of variables at compile time.
edit; I think when all C99 features are implemented it will accept that code of yours but for now you will have to do it the way I showed you.

here's my code, and it works well:
===============================================
typedef struct _SHFILEOPA
{
HWND hwnd;
UINT wFunc;
LPCSTR pFrom;
LPCSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCSTR lpszProgressTitle; // only used if FOF_SIMPLEPROGRESS
} SHFILEOPA, FAR *LPSHFILEOPA;
typedef SHFILEOPA SHFILEOP;
static SHFILEOP sf={0, FO_DELETE, delpath, NULL,
FOF_NOCONFIRMATION+FOF_NOERRORUI,
0,0,0};
int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance,
LPSTR lpszArgument, int nFunsterStil)
{
SHFileOperation((SHFILEOPSTRUCT*)&sf);
return 0;
)
It looks like a bug.
The file shellapi.h uses byte packing for structures. Since FILEOP_FLAGS is defined as a word, all fields after fFlags are actually unaligned. This is obviously what Microsoft wants. The initializer code for structures will not work in this case. Should be fixed in the next beta release of 4.0.

Oh, ok. :)

In 4.0beta4：
typedef struct _SHFILEOPA
{
HWND hwnd;
UINT wFunc;
LPCSTR pFrom;
LPCSTR pTo;
FILEOP_FLAGS fFlags;
BOOL fAnyOperationsAborted;
LPVOID hNameMappings;
LPCSTR lpszProgressTitle; // only used if FOF_SIMPLEPROGRESS
} SHFILEOPA, FAR *LPSHFILEOPA;
typedef SHFILEOPA SHFILEOP;
static SHFILEOP sf={0, FO_DELETE, delfilepath, NULL,
FOF_NOCONFIRMATION+FOF_NOERRORUI,//FOF_ALLOWUNDO+
0,0,0};
SHFileOperation((SHFILEOPSTRUCT*)&sf);

The answer is 42.
Actually, I have no idea what you are tring to say...
