In Microsoft Knowledge Base article Q217114, “How to: Implement Array Arguments in Visual Basic COM Objects for Active Server Pages,” Microsoft says you can’t pass an array to a COM method by value. However, you want to do this for Microsoft Transaction Server (MTS), so here is a workaround that does it ByVal. Add a file called test.asp with this Active Server Page (ASP) code to a virtual Internet Information Server (IIS) directory:
<%dim PassArrayByValWorksdim ary(1)dim iReturnary(0) = "firstone"ary(1) = "2ndone"' pass the array to a non array declared variable then ' pass the non array variable insteadPassArrayByValWorks = arydim objset obj = server.createobject ("prjFormCheck.clsFormCheck")iReturn = obj.formcheck(PassArrayByValWorks, 0)%><%=iReturn%>' build ActiveX dll named "prjFormCheck", name ' class "clsFormCheck" add the function below ' and start it in the VB IDEPublic Function FormCheck(ByVal _ arrFldNameValuePairs As Variant, ByVal _ ErrLogType As Variant) As Variant If IsArray(arrFldNameValuePairs) Then FormCheck = "You can do it!" Debug.Print arrFldNameValuePairs(0) Debug.Print arrFldNameValuePairs(1) Else FormCheck = "Didn't work" End IfEnd functionRight-click on the test.asp file in the virtual directory of IIS and click on Browse. The browser should show “You can do it!”
