Hi

How do we access DLL’s in VB script . this is the way we used to do in legacy

Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

Let me know if there is an alternative way

VBScript cannot do declares. So, there is no way to reference static DLLs, Win32API, etc. Your easiest routes would be to:

1) Think of an alternative way to get the task done
2) Wrap the static DLL call in a COM exposed DLL (which means you must also distribute)
3) Add the code to a legacy script which you invoke from your VBScript plugin

Or, wait for v7 and use P/Invoke in a managed assembly.

This is how I will always wrap function pointers in the future.

Are you just trying to get the current logged in user if so try this

Set wshNetwork = CreateObject("WScript.Network")
strUser = wshNetwork.Username
Msgbox "Current User: " & strUser

What about making a customization that imports almost the entirety of P/Invoke? I'm thinking of something you don't have to change every time you need access to a new function. Of course the plugin would probably be huge, since you're importing practically the entire Win32 library (or at the very least, the portion that does NOT have a .NET counterpart).

If that is what you're after then DynaCall is a great solution for that. DynaCall is a COM DLL that allows you to dynamically call almost any std dll function/api.

You'd install the COM DLL once, and then could use it for any number of APIs. It is really a cool concept.

My only beef is the date in which this was finished (pre-2000) so it could use an update but at least the source is available so it would be a great starting point. I'm thinking this would make a nice .NET extension and I think anything done in .NET gets a generous portion of the COM treatment so it wouldn't be too difficult to turn it into a COM object that earlier versions of SalesLogix could use as well (unless I'm completely off base in regards to .NET and COM).
