Getting logical drives of all Physical drives

[learningvisualc]

Hi all, I have 2 hard disk in my system. I want to get Logical drives of both hard drives i.e. Physical drive 1 contains c: and e: partitions and Physical drive 2 contains d: f: and g: partitions. I have used this code to get the hard disk details.... but it is giving wrong result....

TCHAR szTemp[BUFSIZE];
szTemp[0] = '\0';

if (GetLogicalDriveStrings(BUFSIZE-1, szTemp)) 
{
  TCHAR szName\[MAX\_PATH\];
  TCHAR szDrive\[MAX\_PATH\] = TEXT(" :");
  BOOL bFound = FALSE;
  TCHAR\* p = szTemp;

  do 
  {
    // Copy the drive letter to the template string
    \*szDrive = \*p;


    // Look up each device name
    if (QueryDosDevice(szDrive, szName, BUFSIZE))
    {
		CString str = szDrive;
		str = str+szName;
		//strcat(szDrive , szName);
		m\_Tree\_Ctrl.InsertItem(str,root,TVI\_LAST);
		//m\_Tree\_Ctrl.InsertItem("Physical Drive",root,TVI\_LAST);		
    }

    // Go to the next NULL character.
    while (\*p++);
  } while (!bFound && \*p); // end of string
}
m\_Tree\_Ctrl.Expand(root,TVE\_EXPAND);

It is making a tree like Drives C:\Device\Harddiskvolume1 D:\Device\Harddiskvolume2 E:\Device\Harddiskvolume3 . . . I am not getting what exactly is the problem... Can anybody help me in this... Thanks in advance

This is a function in 1 of my utilities which does what i thiny you are wanting

#include <windows.h>
#include <stdio.h>

LPCSTR FormatSize(QWORD nSize) {
static char szSize[16];
if (nSize < 1024) {
sprintf(szSize, "%uB", nSize);
} else {
char szScales[] = "KMGTPEZY";
int nScale = 0;
for (; nScale < sizeof(szScales); ++nScale) {
if (nSize < 1024 * 1024) {
sprintf(szSize, "%6.2f%cB", nSize / 1024.0f, szScales[nScale]);
break;
}
nSize = (nSize + 512) / 1024;
}
if (nScale == sizeof(szScales)) {
strcpy(szSize, "Unknown Size");
}
}
return szSize;
}

void PrintDrives(char *szDrives) {
DWORD nDrives = GetLogicalDrives();
char szDrive[] = "A:\\";
char szDriveName[MAX_PATH + 1];
int nPrintedDrives = 0;
while (nDrives != 0) {
if (nDrives & 1) {
szDrives[nPrintedDrives] = szDrive[0];
GetVolumeInformation(szDrive, szDriveName, sizeof(szDriveName), NULL, NULL, NULL, NULL, 0);
QWORD nAvaliable;
QWORD nTotal;
QWORD nFree;
if (!GetDiskFreeSpaceEx(szDrive, (PULARGE_INTEGER)&nAvaliable, (PULARGE_INTEGER)&nTotal, (PULARGE_INTEGER)&nFree)) {
nAvaliable = 0;
nTotal = 0;
nFree = 0;
}
if (*szDriveName == 0) {
if (nTotal > 0) {
printf("%s (%s)\n", szDrive, FormatSize(nTotal));
} else {
printf("%s (Unknown Size)\n", szDrive);
}
} else {
if (nTotal > 0) {
printf("%s (%s) [%s]\n", szDrive, FormatSize(nTotal), szDriveName);
} else {
printf("%s (Unknown Size) [%s]\n", szDrive, szDriveName);
}
}
}
nDrives >>= 1;
++szDrive[0];
}
}

int main(int argc, char *argv[]) {
char szDrives[27];
szDrives[26] = 0;
PrintDrives(szDrives);
return 0;
}
