.NET CF: Format Storage Card?

Ok Second Try:

<DllImport("CoreDll.dll")> Shared Function DeviceIoControl(ByVal hDevice
As Integer, ByVal dwIoControlCode As Integer, _
ByVal lpInBuffer As String, ByVal nInBufferSize As
Integer, _
ByVal lpOutBuffer() As Byte, ByVal nOutBufferSize
As Integer, _
ByRef lpBytesReturned As Integer, ByVal
lpOverlapped As Integer) As Integer
End Function
Const OPEN_EXISTING As Integer = 3
Const GENERIC_READ As Integer = &H80000000
Const GENERIC_WRITE As Integer = &H40000000
Declare Function CreateFile Lib "coredll" (ByVal lpFileName As String,
ByVal dwDesiredAccess As Integer, ByVal dwShareMode As Integer, ByVal
lpSecurityAttributes As Integer, ByVal dwCreationDisposition As Integer,
ByVal dwFLagsAndAttributes As Integer, ByVal hTemplateFile As Integer) As
Integer

Private Sub Form1_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim hVolume As IntPtr = CreateFile("\Speicherkarted\Vol:",
(GENERIC_READ Or GENERIC_WRITE), 0, Nothing, OPEN_EXISTING, 0, Nothing)
DeviceIoControl(hVolume, IOCTL_DISK_FORMAT_VOLUME, 0, 0, Nothing,
Nothing, 0, Nothing)
End Sub


But I still dont have the IOCTL_DISK_FORMAT_VOLUME value?

This will be defined in diskio.h (part of the Windows CE SDK). I don't have
this SDK installed so can't tell you what the value is.

I had a difficult time finding that file, for some reason, but a google
search turned up this:

#define IOCTL_DISK_FORMAT_VOLUME CTL_CODE(IOCTL_DISK_BASE, 0x0088,
METHOD_BUFFERED, FILE_ANY_ACCESS)

Really the only way to find out actual values for those things, unless you
want to recreate the structure that the .h files use (macro CTL_CODE,
various values in various parameters to that, etc.), is to actually write a
little C program and run it to get the value. That's how I got the IOCTL
values that OpenNETCF.Net uses for various operations.

This is platform builder file. I had similar problem in formating the
SD card, but above method using IOCTL won't work on newer WM phones.
You should use FormatVolumeEx API to format your SD card. To use this
API, use FATUTIL.DLL. Here is more detail

Thanks

I was risky and looped all values Until I found it
Dirty but working

I'm attempting to do the same thing, however in c#, but it isn't quite
working. Here is the code I'm using:

[DllImport("coredll.dll", EntryPoint = "DeviceIoControl",
SetLastError = true)]
internal static extern int DeviceIoControlCE(
IntPtr hDevice,
int dwIoControlCode,
byte[] lpInBuffer,
int nInBufferSize,
byte[] lpOutBuffer,
int nOutBufferSize,
ref int lpBytesReturned,
IntPtr lpOverlapped);

[DllImport("coredll", SetLastError = true)]
static extern IntPtr CreateFile(String lpFileName, UInt32
dwDesiredAccess, UInt32 dwShareMode, IntPtr lpSecurityAttributes,
UInt32 dwCreationDisposition, UInt32 dwFlagsAndAttributes, IntPtr
hTemplateFile);

int blah = 0;
IntPtr myIoCtrl = CreateFile("Storage Card\Vol:", (0x80000000 |
0x40000000), 0, IntPtr.Zero, 3, 0, IntPtr.Zero);
int result = DeviceIoControlCE(myIoCtrl, 459296, null, 0, null, 0, ref
blah, IntPtr.Zero);

I've checked and 0x80000000 and 0x40000000 are generic_read and
generic_write. I also wasn't sure about the 459296, so I found that
as well, and it seems correct.

// #define CTL_CODE( DeviceType, Function, Method,
Access )
//
// ((DeviceType) << 16) | ((Access) << 14) |
((Function) << 2) | (Method)

DeviceType = 0x00000007
Access = 0
Function = 0x0088
Method = 0

When I call the DeviceIoControlCE function it always returns 0, and my
storage card has not been formatted, any thoughts on how to
troubleshoot this?

Thanks.

Checking the LastWin32Error is a reasonable debugging tool - it will tell
you why it's failing.

And does this even compile? This doesn't look right:
"Storage Card\Vol:"

You have an escaped "V", which I think is undefined.

I'd probably overload the P/Invoke too to pass IntPtr.Zero, not null, to the
in and out data parameters. "null" probably marshals as a zero, but I'd
rather be certain.

I tried changing the nulls to IntPtr.Zero, and as for the escaped
char, sorry, I missed the @ before the string. Checking GetLatError
is returning 87.

87 == invalid parameter, so something you're sending it it doesn't like. Do
you have a working example in C? That's where I'd start.
