I would like to do partition&format functions in my project.
I hope I don't let user do any action when needing to select any
choices.
Using parameters to do both functions successfully.

I don't know MS has to provide any APIs to do these.
(I use SHFormatDrive, but it pops format-dialog, not auto-format)

I think maybe use bat file and use dos command to do.
(like, "format c:/q")

Could anyone teach me how to finish both functions?
(using APIs or DOS commands are ok, just finish both functoins and
user don't any action)

Could you provide a sample code to let me understand?

DeviceIoControl(),
FormatEx(), FormatEx2() (FMIFS.DLL), IFormatEngine interface (Vista)

With DeviceIoControl() (IOCTL_DISK_SET_DRIVE_LAYOUT_EX...)

Dear Sir:

I use the below code to partition physical disk, and it works
successfully.
But I don't how to format after i partitioned new disk.
I don't know the Logical Drives of new disk, so I can't use
other apis to format.
Could you teach me how to do?

Thanks.
