ActiveX control not accepting parameters

I have an activeX control that I built that has public properties.  The control implements the IObjectSafety for Safe for Scripting and Safe for Initialization.  The control loads properly and everything executes correctly until I try to populate the properties.  I have tried jscript, vbscript,  HTML PARAM tags and the result is the same.  It seems to act as if it is not safe for scripting but I cannot tell why.  Any help would be fantastic!

you need to pass the parameters by value since the vbscript have only 1 data type, variant..
post your activex code chunks..

errata: In my 1st post i meant for server components.. this is how you pass parameters to an active x

Many people go way overboard and try to dream up elaborate ways to have a client-side ActiveX control communicating with the server to retrieve values. As long as these values are not dependent on user activities AFTER the ActiveX control has been loaded, try something like this:
 
<%
    strValue = "some string"
    intValue = 5
    Response.Write("<OBJECT clsid=[blah blah]>")
    Response.Write("<PARAM NAME=INT VALUE=""<%=intValue%>"">")
    Response.Write("<PARAM NAME=INT VALUE=""<%=intValue%>"">")
    Response.Write("</OBJECT>")
%>
 
ANd now in server-side JavaScript:
 
<script language=JavaScript runat=server>
 
    var strValue = "some string";
    var intValue = 5;
    Response.Write("<OBJECT clsid=[blah blah]>");
    Response.Write("<PARAM NAME=INT VALUE=\"<%=intValue%>\">");
    Response.Write("<PARAM NAME=INT VALUE=\"<%=intValue%>\">");
    Response.Write("</OBJECT>");
 
</script>

I have tried the method you suggested to the same result.  Any code that references a PARAM tag or in a script tag such as ExportCtl.ExportData will not execute nor will any code that follows the call to the object properties.  The code is run on the client so I cannot use the response.write script option.  I am accessing the server variables and loading them into the control.  Here is a code snippet:

     sub InitExportCtl()
          dim tmpLocalPath
          on error goto 0
          msgbox "InitExportCtl"
          if laNode => 0 then
               msgbox "Before first Property Access"
               ExportCtl.ExportData1 = oCaseFolder(0)
               msgbox "Before second Property Access"
               ExportCtl.FileExt1 = aFileList(0)
               msgbox oCaseFolder(0)
               msgbox aFileList(0)
          end if
          if laNode => 0 then
               ExportCtl.ExportData2 = oCaseFolder(1)
               ExportCtl.FileExt2 = aFileList(1)
               msgbox oCaseFolder(1)
               msgbox aFileList(1)
          end if
          if laNode => 0 then
               ExportCtl.ExportData3 = oCaseFolder(2)
               ExportCtl.FileExt3 = aFileList(2)
               msgbox oCaseFolder(2)
               msgbox aFileList(2)
          end if
          if laNode => 0 then
               ExportCtl.ExportData4 = oCaseFolder(3)
               ExportCtl.FileExt4 = aFileList(3)
               msgbox oCaseFolder(3)
               msgbox aFileList(3)
          end if
          if laNode => 0 then
               ExportCtl.ExportData5 = oCaseFolder(4)
               ExportCtl.FileExt5 = aFileList(4)
               msgbox oCaseFolder(4)
               msgbox aFileList(4)
          end if
          tmpLocalPath = "<%=Path%>"
          ExportCtl.DefaultDir = tmpLocalPath
          msgbox tmpLocalPath
     end sub

The msgboxes are for debugging to see if the code is executed.  Here is the Object tag:

<OBJECT ID="ExportCtl" CLASSID="CLSID:5FD98568-6543-45C9-83FC-864C29609AF9"  codebase="Export.CAB#version=1,0,0,0" Language=vbscript>
</OBJECT>

The code here is just the latest version.  I have tried Param tags, jscript, vbscript etc...  to no avail.

Hi,

Did you try testing the ActiveX Control in VB before putting it in the ASP page?

Try testing the same piece of code in VB.
Add this control to a form and test the code(the snippet you had posted) that passes/accepts values from this Activex Control.

Please try this if you haven't done so, and give your comments. I think i could guide you from that point.

If this helps in any way..

Is Export.CAB available to the user?  In the same folder as the rest of the code?

We found out what the issue was. Thanks for all of your help.  There was a server side script tag (%>)embedded within a comment that was causing the issue.  When the line was deleted the control performed correctly.
