Ladies and gentlemen: I now define a one-dimensional array in JavaScript, then call the DLL object written by VB, assign a value to this array in the DLL object, and then read the assigned array in JavaScript. How to operate.
DLL object:
Testprj.test
Public Sub Test (StrName () as Variant)
StrName (0) = "MR"
StrName (1) = "Zhang"
End Sub
Javascript:
<script language= ' JavaScript ' >
var a=new Array ();
var test=new activeobjectx ("Testprj.test");
Test.test (A);
Response.Write (A.length);
</Script>
Excuse me, where is the error???

Thank you for using Microsoft products.
You can create Acivexdll in VB, process functions with array parameters, and call Acivex object functions in ASP. Because the array object of JavaScript is stored in a different way from the array in VB, the JavaScript array object as an argument to the Vbactivexdll function will have an error of type mismatch. It is recommended that you use VBScript in ASP.
The following example, first in VB to establish Acivexdll project, the project name is Asparray, class name Clsarray
Public Function testarray (ByRef varray as Variant) as String
Dim ncnt as Integer
' Check that ' the argument passed are an Array
If not IsArray (varray) Then
Testarray = "Parameter is isn't an Array"
Exit Function
End If
For ncnt = LBound (varray) to UBound (Varray)
' Change Array Element
Varray (ncnt) = "AQQQ"
Next ncnt
Testarray = "Parameter is an Array"
End Function
Referencing the Asparray.clsarray object in ASP,
<%
Dim otestobj, Vmyarray (2), Vrtnvalue
Vmyarray (0) = "Element 1"
Vmyarray (1) = "Element 2"
Vmyarray (2) = "Element 3"
Set otestobj = Server.CreateObject ("Asparray.clsarray")
Vrtnvalue = Otestobj.testarray (vmyarray)
Response.Write ( vrtnvalue )
%> <br>
Vmyarray (1) = <%=vmyarray (1)%>

You can use the ToArray () method of the VBArray object in JavaScript to convert the array of VBScript (array) into a JavaScript array, but as of the current VBScript (4.0) version, There is no way to convert a JavaScript array into a VBScript array.
For more information, refer to the Passingarraysfromvbscripttojscript section of the following documentation:
