I think you misunderstood the question. memcpy will not help the OP in this case!

Well I got it that is IOCTL_disk_create_disk.

There's a reason the OS does this at boot time - when the OS is fully running, the disk is potentially changing all the time, invalidating the check. And what if there's a problem in a loaded file? Why is the OS doing this all the time? Mine doesn't! And which OS... Iain. I have now moved to Sweden for love (awwww). If you're in Scandinavia and want an MVP on the payroll (or happy with a remote worker), or need cotract work done, give me a job! http://cv.imcsoft.co.uk/[^]

Thanks for your kind support. I will apply it today. Thanks Madan

I suspect DeviceIoControl[^] and the IOCTL_DISK_SET_PARTITION_INFO_EX[^] control code may point you in the right direction. I don't know if they'll actually let you do what you want, though - that function may only be accessible through lower level NT functions that are (publicly) undocumented, or documented in the device driver documentation? In fact, looking a bit further, I suspect IoSetPartitionInformationEx[^] is probably the function you need - but that's part of the NT API, not the Win32 API.

You need to run your application by making it a service or u first schedule your application to run at startup through your windows task scheduler. then it will work fine in vista. Have a great Day.

Sorry sir ok as you wish.But i always waiting for responce.. Thx's in advance

mmc.exe (Microsoft Management Console) is the host executable that actually runs when you open diskmgmt.msc. So spawn mmc.exe by using CreateProcess(). For instance, // Startup Info. STARTUPINFO si; ZeroMemory( &si, sizeof(si) ); si.cb = sizeof(si); // Process Info. PROCESS_INFORMATION pi; ZeroMemory( &pi, sizeof(pi) ); // Start the child process. CreateProcess( NULL, _T("mmc.exe diskmgmt.msc"), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi ); Well, If you just want to open the DiskManagementConsole, then ShellExecute() can do it more easily. ShellExecute( 0, _T("open"), _T("diskmgmt.msc"), 0, 0, SW_SHOW ); Regards, Jijo. _____________________________________________________ http://weseetips.com[^] Visual C++ tips and tricks.
