how to change drive name??

[Phiru]

I am working on making virtual drive(which is showen like a real drive like local disk). when i run my project, the drive name is always "Local disk".
I want to change it to like "TEST" or something.

I am pretty sure that I can change it cuz windows has this function.

I can change the name manually. right?

Actually, I used SetVolumeLabel('virtual drive letter', 'new drive name") function, but
it failed. I couldn't find any reason.

anyone has any ideas??

Help me. Thanks in advance.

You can set volume label from within windows explorer ? Your virtual file system must support this.

Did you bother to capture the error with GetLastError and figure out what it was?

O dont know what you are talking about because I cant change my drive names, and Im on XP

Generally, drive name is set to "Local Disk".
You can change the name manually from within windows explorer. Added, It doesn't matter
what sort of OS you use.

And I posted it "I used SetVolumeLabel function, but it failed." which didn't mean
it has a complie error or run time error.
The function returns 0 or something when it fails to change the VolumeLabel(Drive Name).

I need some method to change it. Thanks :)

Whenever you are calling SetVolumeLabel() if it returns 0 (failure) immediately call GetLastError() and print out the result:

#include <windows.h>

int main()
{
  int result = SetVolumeLabel("G:\\","Foobar");
  if(!result)
  {
    DWORD ErrNo = GetLastError();
    LPSTR ErrMsg = 0;
    FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER|FORMAT_MESSAGE_FROM_SYSTEM|FORMAT_MESSAGE_IGNORE_INSERTS,0,ErrNo,MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),(LPSTR)&ErrMsg,0,0);
    MessageBox(0,ErrMsg,"Last Error Message Received",0);
    LocalFree(ErrMsg);
  }
}

In my case the G: drive doesn't exist so it returned "The system cannot find the path specified"
