get appPath from registry

ok, i figure i need to use the GetSetting() function, but it doesn't seem to work right here is my code

dim WinampPath

WinampPath = GetSetting("Winamp", "Winamp", Default)

it should return "c:/program files/winamp" but i get 0 instead.

any help much appreciated

Winamp doesn't save its path in the "VB and VBA program settings" key. If you're trying to get the path where Winamp is installed, you will need to user APIs, GetSetting won't be of any use.

For example:

VB Code:

Option Explicit
 
Private Const HKEY_CLASSES_ROOT = &H80000000
Private Const WINAMP_REG_KEY = "WinAmp.File\shell\play\command"
Private Const KEY_QUERY_VALUE = &H1
 
Private Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" _
  (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, _
  ByVal samDesired As Long, phkResult As Long) As Long
Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" _
(ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, _
lpData As Any, lpcbData As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
 
Public Function GetWinampPathAndExeFile() As String
'Finds the path of winamp
    
    Dim WinampPath As String
    
    WinampPath = RegGetString(HKEY_CLASSES_ROOT, WINAMP_REG_KEY, "")
    If Len(WinampPath) < 8 Then GetWinampPathAndExeFile = "": Exit Function
    WinampPath = Mid(WinampPath, 2, Len(WinampPath) - 7)
    GetWinampPathAndExeFile = WinampPath
End Function
 
Public Function GetWinampPath() As String
    Dim A As Integer
    GetWinampPath = GetWinampPathAndExeFile
    
    A = 1
    Do While InStr(A + 1, GetWinampPath, "\")
        A = A + 1
    Loop
    GetWinampPath = Left(GetWinampPath, A)
End Function
 
Public Function RegGetString$(hInKey As Long, ByVal subkey$, ByVal valname$)
    Dim RetVal$, hSubKey As Long, dwType As Long, SZ As Long, v$, R As Long
    RetVal$ = ""
    R = RegOpenKeyEx(hInKey, subkey$, 0, KEY_QUERY_VALUE, hSubKey)
    If R <> 0 Then Exit Function
    SZ = 256
    v$ = String$(SZ, 0)
    R = RegQueryValueEx(hSubKey, valname$, 0, dwType, ByVal v$, SZ)
    If R = 0 And dwType = 1 Then
        RetVal$ = Left(v$, SZ - 1)
    Else
        RetVal$ = ""
    End If
 
 
    If hInKey = 0 Then R = RegCloseKey(hSubKey)
    RegGetString$ = RetVal$
End Function

and then:

VB Code:

MsgBox GetWinampPath
