Passing flags to program via ShellExecute

I am writing a program to manage my mp3 playlists, i have currently got it to open a playlist for an album - although i can only open 1 album at a time. I would like to pass the option to enqueue files aswell as opening one set at a time. Looking at the winamp exe i need to call [winamp.exe] /ADD [file name for playlist].

i currently use
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

this function like this....

ShellExecute 0, "Open", sPlaylists.Item(List1.ListIndex + 1), "", "", SW_SHOW

but i would also like to pass the "/ADD" flag to append to the playlist.

I suggest you to use WinExec instead:

Declare Function WinExec Lib "kernel32" Alias "WinExec" (ByVal lpCmdLine As String, ByVal nCmdShow As Long) As Long

WinExec("your command and arguments and flags here", 1)

Don't forget to give correct exe's full path

thanks for your fast reply,

is there no way to do it without the full path as with shellexecute. i am planning to make the application and distribute it over the web so out like it to run with the default players.

If the default player is not winamp, then do you still want to pass the /ADD switch?

If you want to pass multiple files or some switches, then you have to call application by its name, including path, with exception of applications that are in windows folder or in current active folder. But there are many alternatives to obtain application full path by reading the Windows Registry.

for those of you who are interested i solved the problem like this

Dim sCommand As String
sCommand = ReadRegistry(HKEY_CLASSES_ROOT, "Applications\Winamp.exe\shell\Enqueue\command", "")
sCommand = Replace(sCommand, "%1", sPlaylists.Item(List1.ListIndex + 1))
WinExec sCommand, SW_SHOW
