Hi all,

I want to get my hard disk name I am using WMI to get it. I have Initialized com using CoInitializeEx, then i have set security levels using CoInitializeSecurity, then i Obtain the initial locator to WMI, then i have Connected to WMI through the IWbemLocator::ConnectServer method but my problem is i am not getting the right api to get hard disk name.. how can i get it???

IWbemServices *pSvc = NULL;
	
hres = pLoc->ConnectServer(
         _bstr_t(L"ROOT\\CIMV2"), // Object path of WMI namespace
         NULL,                    // User name. NULL = current user
         NULL,                    // User password. NULL = current
         0,                       // Locale. NULL indicates current
         NULL,                    // Security flags.
         0,                       // Authority (e.g. Kerberos)
         0,                       // Context object 
         &pSvc                    // pointer to IWbemServices proxy
         );

can anybody help me in this

thanks in advance

First of all Set IWbemServices proxy security so that WMI service can impersonate the client by calling CoSetProxyBlanket.

Then Get Physical disks Installed on the system using ExecQuery().

Did you try to execute query using pSvc like
example from MSDN

// For example, get the name of the operating system
    IEnumWbemClassObject* pEnumerator = NULL;
    hres = pSvc->ExecQuery(
        bstr_t("WQL"), 
        bstr_t("SELECT * FROM Win32_OperatingSystem"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
        NULL,
        &pEnumerator);

for disk information
you have to try some thing like

SELECT * from Win32_DiskDrive

I hope it helps.

Sandip.

Which property were you thinking would hold the volume name? Perhaps you meant Win32_LogicalDisk instead.

Oops, i didn't see that OP mentioned volume name. Smile | :)

But for volume names do we need WMI, i think we have some API.
GetVolumeInformation or something not sure.. Am i correct??

No, but the OP asked for it.

Yes, and I would have suggested it had it not been for the WMI requirement.

WriteFile in Vista

Hi,
I am getting error no 5 while writing in my C Drive which is having windows vista.

What should I do?

I tried with Dismount volume that is working with all drive except c:(OS drive).

What should I do that?

Error 5 == access denied. Sounds like a permissions thing. I suspect you aren't permitted to write to c:\? The same thing happens when writing to c:\ with a default install of XP as well - it's not necessarily a Vista thing.

john56321-Dec-08 21:30

This is only wuth vista becuase I have checked with Xp and all, this problem is with vista only.

You cant write a file where you want, you need to have the write rights. A nice place to write is the User Directory who started the writing process.

Thank you but I have set all security attributes. I am facing the problem only Os drive of Vista.

Is there any way to skip the security permission?

KarstenK1-Dec-08 22:04

There is always a way. Your process needs administrative rights. But thats no good practise.

I guess your not so seasoned in Windows programming, so you got to learn a lot.
Once again: You better read and understand the right managment in Vista.

Of course not - that's baked into the OS - if there was a way around security, then writing viruses would be even more common than they already are. Think of it like the locks on your car - is there any easy way around them (yes, you can pick them, but htere's no legitimate way around them).

No, you haven't.

You need to set folder permissions to allow the desired access by the
appropriate user(s).

One other thing you might try - Process Monitor[^] can help you see exactly what your process is doing in terms of file accesses and things - that might give an extra level of detail that you need?
