The Win32 API includes a pair of functions that let you format and copy diskettes from your programs:
Private Declare Function SHFormatDrive _ Lib "shell32" (ByVal hwnd As Long, _ ByVal Drive As Long, _ ByVal fmtID As Long, _ ByVal options As Long) As LongPrivate Declare Function GetDriveType _ Lib "kernel32" _ Alias "GetDriveTypeA" _ (ByVal nDrive As String) As LongAdd two command buttons to your form, named cmdDiskCopy and cmdFormatDrive, and place this codeinto their Click events:
Private Sub cmdDiskCopy_Click() ' DiskCopyRunDll takes two ' parameters- From and To Dim DriveLetter$, DriveNumber&, _ DriveType& Dim RetVal&, RetFromMsg& DriveLetter = UCase(Drive1.Drive) DriveNumber = (Asc(DriveLetter) - _ 65) DriveType = GetDriveType_ (DriveLetter) If DriveType = 2 Then 'Floppies, _ etc RetVal = Shell_ ("rundll32.exe " & _ "diskcopy.dll," _ & "DiskCopyRunDll " & _ DriveNumber & "," & _ DriveNumber, 1) Else ' Just in case RetFromMsg = MsgBox_ ("Only floppies can be " & _ "copied", 64, _ "DiskCopy Example") End IfEnd SubPrivate Sub cmdFormatDrive_Click() Dim DriveLetter$, DriveNumber&, _ DriveType& Dim RetVal&, RetFromMsg% DriveLetter = UCase(Drive1.Drive) DriveNumber = (Asc(DriveLetter) - _ 65) ' Change letter to Number: A=0 DriveType = GetDriveType_ (DriveLetter) If DriveType = 2 Then _ 'Floppies, etc RetVal = SHFormatDrive(Me.hwnd, _ DriveNumber, 0&, 0&) Else RetFromMsg = MsgBox_ ("This drive is NOT a " & _ "removeable drive! " & _ "Format this drive?", _ 276, "SHFormatDrive Example") If RetFromMsg = 6 Then ' UnComment to do it... 'RetVal = SHFormatDrive_ (Me.hwnd, _ ' DriveNumber, 0&, 0&) End If End IfEnd SubAdd one DriveListBox control named Drive1:
Private Sub Drive1_Change() Dim DriveLetter$, DriveNumber&, _ DriveType& DriveLetter = UCase(Drive1.Drive) DriveNumber = (Asc(DriveLetter) - _ 65) DriveType = GetDriveType_ (DriveLetter) If DriveType <> 2 Then _ 'Floppies, etc cmdDiskCopy.Enabled = False Else cmdDiskCopy.Enabled = True End IfEnd SubBe careful: this function can even format the hard disk.
