Ok, lets take another one, winhelp.c WinHelpW->A
OK, I have to warn you I haven't looked at the code, so I'll just go by what I see in this email.
I take whatever is in WinHelpA and move it into WinHelpW with the fallowing changes:
-BOOL WINAPI WinHelpW( HWND hWnd, LPCWSTR helpFile, UINT command, ULONG_PTR dwData ) +BOOL WINAPI WinHelpW( HWND hWnd, LPCWSTR helpFile, UINT wcommand, ULONG_PTR dwData )
why did they call them wcommand in WinHelpA and command in WinHelpW ?? (msdn calls them uCommand but the code uses wcommand...)
I don't see why, it should be named the same in both versions if it's encoding independent.
-hDest = FindWindowA("MS_WINHELP", NULL); +hDest = FindWindowW("MS_WINHELP", NULL);
You can't to that directly, as we don't support Unicode literals. You need to do that by hand:
WCHAR clsName[] = { 'M', 'S', '_', 'W', 'I', 'N', 'H', 'E', 'L', 'P', 0 }; hDest = FindWindowW(clsName, NULL);
if (!(hDest = FindWindowA("MS_WINHELP",NULL)))
if (!(hDest = FindWindowW("MS_WINHELP",NULL)))
Ditto, just do if (!(hDest = FindWindowW(clsName, NULL);
- return SendMessageA(hDest, WM_COPYDATA,
(WPARAM)hWnd, (LPARAM)&cds);
- return SendMessageW(hDest, WM_COPYDATA,
(WPARAM)hWnd, (LPARAM)&cds);
OK.
and now I need to put a call in WinHelpA to WinHelpW after converting LPCSTR lpHelpFile ?
Yes.
