VB Forum / Win API / July 2008

I found the following declarations in some code on the net. Where can I find
documentation on the parameters of the functions?

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

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal
lpClassName As String, ByVal lpWindowName As String) As Long

Thanks,

Steve
