Disk Space Problems

[Alpinestar]

Hi Guys

I'm attempting to write a program that checks the sizes of 2 files (database file and index file). It then multiples the total size by 3 ( to allow database growth), adds 600 mb for a new service installation and minuses this from the hard drive free space.

If the total is negative then a Insufficient space is displayed. My problem is that all the file sizes and in a different format so don't add up correctly.

I know that this could be v easy for someone, below is my code.

CODE

#include <GUIConstants.au3>

$Form1 = GUICreate("Disk Space", 410, 349, 193, 115)

$SimsMDF = FileGetSize("C:\Microsoft SQL Server 2005\MSSQL.1\Data\master.mdf")

$tSimsMDF = $SimsMDF /1048576

$lbMDF = GUICtrlCreateLabel("1st File Size", 16, 40, 109, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$lbLDF = GUICtrlCreateLabel("2nd File Size", 16, 71, 101, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$Label1 = GUICtrlCreateLabel("SQL Express Install", 12, 108, 124, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$Label2 = GUICtrlCreateLabel("Free Space C:\", 12, 140, 92, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$Label3 = GUICtrlCreateLabel("TOTAL", 10, 184, 44, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$Label4 = GUICtrlCreateLabel("VERDICT", 10, 245, 59, 20)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$nFREESPACE = DriveSpaceFree("C:")

$tFREESPACE = $nFREESPACE /1048576

$inFREESPACE = GUICtrlCreateInput($nFREESPACE, 188, 139, 120, 20, $WS_BORDER)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$Express = 600

$inEXPRESS = GUICtrlCreateInput($Express & " MB", 188, 104, 120, 20, $WS_BORDER)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$SimsLDF = FileGetSize("C:\Microsoft SQL Server 2005\MSSQL.1\Data\master.ldf")

$tSimsLDF = $SimsLDF /1048576

$inLDF = GUICtrlCreateInput($tSimsLDF & " MB", 188, 75, 120, 20, $WS_BORDER)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

$inMDF = GUICtrlCreateInput($tSimsMDF & " MB", 188, 44, 120, 20, $WS_BORDER)

GUICtrlSetFont(-1, 10, 400, 0, "Arial")

GUISetState(@SW_SHOW)

$nTOTAL = $tSimsMDF + $tSimsLDF + $Express

$tSIMSTOTAL = ($tSimsLDF & $tSimsLDF /1048576)

$inTOTAL = GUICtrlCreateInput($nTOTAL, 188, 181, 120, 20)

GUICtrlSetFont(-1, 10, 800, 0, "Arial")

$tempcalculate = $tSIMSTOTAL *3

$tmpcalc = $tempcalculate + $Express

$calculate = $tmpcalc - $nFREESPACE

If $calculate < -1 Then

$inVerdict = GUICtrlCreateInput("Insufficient Space", 188, 242, 120, 20, $WS_BORDER)

ElseIf $calculate > -1 Then

$inVerdict = GUICtrlCreateInput("Sufficient Space", 188, 242, 120, 20, $WS_BORDER)

Else

$verdict = GUICtrlCreateLabel($calculate, 40, 136, 63, 28)

EndIf

While 1

$nMsg = GUIGetMsg()

Switch $nMsg

Case $GUI_EVENT_CLOSE

Exit

EndSwitch

WEnd

Remarks

Does not work on directories.

Divide result by 1024 to get kilobyte equivalent, or divide by 1048576 to get megabyte equivalent.

Thanks for the reply

My application is using only files and is dividing by 1048576. However I'm still getting strange result.

Here's a WMI query for the free space on a drive:

Dim $sComputer = "." 
Dim $sDisk = "C:" 

$oWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $sComputer & "\root\cimv2")
$colDisk = $oWMIService.ExecQuery ("Select * from Win32_LogicalDisk Where DeviceID = " & "'" & $sDisk & "'")

For $oDisk In $colDisk
$spacecalc = $oDisk.FreeSpace
MsgBox(0,"","Approximately " &($spacecalc/(1024*1024)) &" GB free on drive " &$sDisk)
Next

Too many math and logic errors to list. This performs the basis without the irrelevant GUI mess:

#include <GUIConstants.au3>

$SimsMDF = FileGetSize(@WindowsDir & "\explorer.exe")
$tSimsMDF = $SimsMDF / 1048576 ; Convert to MB

$nFREESPACE = DriveSpaceFree("C:") ; Already is in MB

$Express = 600

$nTOTAL = $tSimsMDF + $Express

; $tSIMSTOTAL = ($tSimsLDF & $tSimsLDF / 1048576) ; What is this for?!

$inTOTAL = GUICtrlCreateInput($nTOTAL, 188, 181, 120, 20)

$tempcalculate = $nTOTAL * 3
$tmpcalc = $tempcalculate + $Express
$calculate = $nFREESPACE - $tmpcalc

If $calculate < 0 Then
    MsgBox(16, "Insufficient Space", "Disk freespace = " & $nFREESPACE & @CRLF & _
            "Space required = " & $tmpcalc)
Else
    MsgBox(64, "Sufficient Space", "Disk freespace = " & $nFREESPACE & @CRLF & _
            "Space required = " & $tmpcalc)
EndIf

Thanks for that, works a treat !
