Hi ,
m new in VB6. Can anyone let me know what exactly this segment means?

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

Code:

Private Sub Label6_Click()

ShellExecute Me.hWnd, _
        vbNullString, _
        "http://zsoftwares.googlepages.com/VBprograms.htm", _
        vbNullString, _
        "c:\", _
        SW_SHOWNORMAL
End Sub

thanks.

The DECLARE is telling VB how to access a function that is in a DLL.

The Label6_Click then uses that information to, indeed, call that function in that DLL.

Looks to me like it's asking the command shell to open up a browser and send the browser to that URL.
