[SOLVED] DriveGetDrive + Comparison

[johnmcloud]

Hi Guys,

For work i need to know how which drive letter are avaiable and take the first.

For now i have make this script:

expandcollapse popup

Local $aArray = DriveGetDrive("ALL")
Local $avArray[24]

$avArray[0] = "A:\"
$avArray[1] = "B:\"
$avArray[2] = "C:\"
$avArray[3] = "D:\"
$avArray[4] = "E:\"
$avArray[5] = "F:\"
$avArray[6] = "G:\"
$avArray[7] = "H:\"
$avArray[8] = "I:\"
$avArray[9] = "J:\"
$avArray[10] = "K:\"
$avArray[11] = "L:\"
$avArray[12] = "M:\"
$avArray[13] = "N:\"
$avArray[14] = "O:\"
$avArray[15] = "P:\"
$avArray[16] = "Q:\"
$avArray[17] = "R:\"
$avArray[18] = "S:\"
$avArray[19] = "T:\"
$avArray[20] = "U:\"
$avArray[21] = "V:\"
$avArray[22] = "X:\"
$avArray[23] = "Y:\"
$avArray[24] = "Z:\"

If @error Then
; An error occurred when retrieving the drives.
MsgBox(4096, "DriveGetDrive", "It appears an error occurred.")
Else
For $i = 1 To $aArray[0]
     ; Show all the drives found and convert the drive letter to uppercase.
     ConsoleWrite(StringUpper($aArray[$i]) & "\" & @CRLF)
Next
EndIf

Hope is a good approach.

The result of DriveGetDrive is:

C:\
D:\
W:\
X:\
Y:\
Z:\

So i want to compare mine letter with all avaible ( so the two array ), subtract from the complete list C-D-W-X-Y-Z and give me a new list, then take the fist drive avaiable ( in my case is E:\ = [1] )

Some suggestion?

Thanks

If you need the first drive available for function DriveMapAdd you couldy just pass "*" to get the same result.

[johnmcloud]

Water you are always here when i need help

I have try:

ConsoleWrite(DriveMapAdd("*"))

But give me error, the second parameter is:

Remote Share --> The remote share to connect to in the form servershare.

What i need to write?

Thanks

The second parameter has to be the share you want to connect to. "" + Servername + "" + sharename. Sharename is something like "C$" for a complete drive on another computer or "name$" for a directory.

Where do you want to connect to?

[johnmcloud]

I don't need to connect the drive, i need only to know the first drive letter avaiable

[water]

But why do you want to know the first free drive letter? What do you want to do with this information?

[johnmcloud]

It's a complex question to explain for me in my not native language, any way to compare the two result?

EDIT: Maybe like this:

#include <Array.au3>
Global $aArrayA[10] = ["A", "B", "C"]
Global $aArrayB[10] = ["A"]

For $a = UBound($aArrayA) - 1 To 0 Step -1
    For $b = 0 To UBound($aArrayB) - 1
        If $aArrayA[$a] = $aArrayB[$b] Then
            _ArrayDelete($aArrayA, $a)
            ExitLoop
        EndIf
    Next
Next
_ArrayDisplay($aArrayA, "Result")

I don't like ArrayDelete

This will return the next free drive letter:

For $i = Asc("A") To Asc("Z")
    $sDrive = DriveGetType(Chr($i) & ":")
    If @error Then ExitLoop
Next
MsgBox(0, "", Chr($i) & " is the next free drive letter")

Cool thanks, more faster and shorter then mine solution

What's wrong with _GetUnusedDrives()?

[water]

Nothing wrong with that.

But as the OP only needed the first free drive letter my code is a bit shorter and easier to understand

[guinness]

OK.
