Get available drives in Windows

[fuzzy70]

This is a bit of a hack to be honest (although it does work) & until I sort out a cleaner method it will do

BTW this has been written & tested on Windows 7 only, I have none of the other Windows OS'es available at this time to test it.

EDIT:

Have found a way of accessing the drive letters from wrapping a function from the Windows kernel32.dll for those who have a full license . It only gives the drive letters at the moment (no types like disk/cd etc or filesystem) but it sure is cleaner

TYPE Kernel32

DECLARE_C_ALIAS(GetLogDrives, "kernel32.dll", "GetLogicalDrives",(void),int);

FUNCTION Get_Log_Drives:
INLINE
return GetLogDrives();

ENDFUNCTION

FUNCTION Available_Drives:

LOCAL bittest% = 1
LOCAL loop%,bitcompare%,result%

result = self.Get_Log_Drives()
FOR loop = 0 TO 25

bitcompare = bAND(result,bittest)

IF bitcompare <> 0
DIMPUSH self.drive_letter$[],CHR$(loop+65)
ENDIF

bittest = ASL(bittest,1)

NEXT

ENDFUNCTION

ENDTYPE


GLOBAL drives AS Kernel32

GLOBAL loop%,text$

drives.Available_Drives()

FOR loop = 0 TO BOUNDS(drives.drive_letter$[],0)-1

text$ = "Drive " + drives.drive_letter$[loop] + ": = Found"

PRINT text$,0,loop*8
