Default Drive/Windows Directory

How do I find out which is the default drive (the one with the windows os installed)?
Also how do I know the default windows directory/temporary files directory etc?

Would appreciate some help here.

Thx.

One more thing, is it possible for me to read a whole line from a text file into an array rather than a string variable?

api - GetSystemDirectory

Code:

---

Private Declare Function GetSystemDirectory Lib "kernel32" Alias "GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long
Private Sub Form_Load()
    'KPD-Team 1998
    'URL: http://www.allapi.net/
    'E-Mail: [email protected]
    Dim sSave As String, Ret As Long
    'Create a buffer
    sSave = Space(255)
    'Get the system directory
    Ret = GetSystemDirectory(sSave, 255)
    'Remove all unnecessary chr$(0)'s
    sSave = Left$(sSave, Ret)
    'Show the windows directory
    MsgBox "Windows System directory: " + sSave
End Sub

' GetTempPath example

    Timer1.Enabled = True
    Dim strTemp As String, strUserName As String
    'Create a buffer
    strTemp = String(100, Chr$(0))
    'Get the temporary path
    GetTempPath 100, strTemp
    'strip the rest of the buffer
    strTemp = Left$(strTemp, InStr(strTemp, Chr$(0)) - 1)

    'Create a buffer
    strUserName = String(100, Chr$(0))
    'Get the username
    GetUserName strUserName, 100
    'strip the rest of the buffer
    strUserName = Left$(strUserName, InStr(strUserName, Chr$(0)) - 1)

    'Show the temppath and the username
    MsgBox "Hello " + strUserName + Chr$(13) + "The temp. path is " + strTemp
End Sub

Thx a lot.
How do I make a file in a specified directory by the user? Say, I take the system directory or ask user to input a directory and then make a temp file in it.

Also is it possible to delete a temp file after using it?
