Hallo erstmals!
Soviel vorweg: Ich arbeite mit Microsoft Visual C++ und muss für ein Programm das Diskettenlaufwerk formatieren können. Vorbildlich habe ich mich schon umgesehen und wurde auch schon fündig. Jedoch will es nicht laufen:
//--------------------------------------------------------------------------------------------------
#if !defined(SHFMT_OPT_FULL)
#if defined (__cplusplus)
extern "C" {
#endif
/*****************************************************************
The SHFormatDrive API provides access to the Shell's format
dialog box. This allows applications that want to format disks to bring
up the same dialog box that the Shell uses for disk formatting.
PARAMETERS
hwnd = The window handle of the window that will own the
dialog. NOTE that hwnd == NULL does not cause this
dialog to come up as a "top level application"
window. This parameter should always be non-null,
this dialog box is only designed to be the child of
another window, not a stand-alone application.
drive = The 0 based (A: == 0) drive number of the drive
to format.
fmtID = Currently must be set to SHFMT_ID_DEFAULT.
options = There are currently only two option bits defined.
SHFMT_OPT_FULL
SHFMT_OPT_SYSONLY
SHFMT_OPT_FULL specifies that the "Quick Format"
setting should be cleared by default. If the user
leaves the "Quick Format" setting cleared, then a
full format will be applied (this is useful for
users that detect "unformatted" disks and want
to bring up the format dialog box).
If options is set to zero (0), then the "Quick Format"
setting is set by default. In addition, if the user leaves
it set, a quick format is performed. Under Windows NT 4.0,
this flag is ignored and the "Quick Format" box is always
checked when the dialog box first appears. The user can
still change it. This is by design.
The SHFMT_OPT_SYSONLY initializes the dialog to
default to just sys the disk.
All other bits are reserved for future expansion
and must be 0.
Please note that this is a bit field and not a
value, treat it accordingly.
RETURN
The return is either one of the SHFMT_* values, or if
the returned DWORD value is not == to one of these
values, then the return is the physical format ID of the
last successful format. The LOWORD of this value can be
passed on subsequent calls as the fmtID parameter to
"format the same type you did last time".

Folgende Fehlermeldung erscheint beim Kompilieren:
> error C2146: Syntaxfehler : Fehlendes ';' vor Bezeichner 'WINAPI'
Ich habe mir gedacht das liege am DWORD. Folgend versuchte ich es mit abändern DWORD in double. Ging nicht (Ja, ich bin noch ein blutiger Anfänger.) und folgende Fehlermeldung erschien:
> error C2146: Syntaxfehler : Fehlendes ';' vor Bezeichner 'SHFormatDrive'
Wer kann helfen? Wer kennt einen besseren Weg? Möglichst Hilfe mit Source. Danke schon im Voraus.
