Using the latest build as of today.

I'm having trouble using any ActiveX controls but the IE one in demo.zml. I've tried several, including ones I've built, the standard VB textbox, and Microsoft's rich text box. In each case the first script to try to use it gives me an "object required" scripting error. I've tried scaling back the demo.zml example to accomodate this, and everying looks find up until the point at which I make the control switch.

The declaration doesn't produce an error message (swapping in a different control name in the activex block) but the first attempted use in a script does (even if it's the Navigate button that works for Explorer). The control doesn't appear to be loaded (same grey background color on the zApp form, wheras the textbox I was trying is white by default and the IE control shows up white).

Has anyone else had any success with this?

The three things I'm trying to do that I didn't find in the examples are:
1. ActiveX control
2. COM object that isn't a control
3. a few global variables

I know that I can simulate (2) if I can do (1), and (3) if I can do (1) or (2).

Can you send me an ActiveX control file to play with along with your script? The IE ActiveX control is the only one that I have tried, and it's very possible that IE is doing something really wierd.

For 2) you need to declare your COM object in your script just like you normally do in VB Script. So, somewhere in your main WINDOW declaration in your ZML file you need something like:

Tarn,

Here is a quick example I whipped together to demonstrate using the treeview control from visual basic. Just copy and paste this into notepad and save as "ActiveX_Test.zml".

<window name="main">
<activex name='treex' align='client' classname='MSComctlLib.TreeCtrl'/>
<script>
with treex
.Nodes.Add , , "RootKey", "Root Node"
.Nodes.Add "RootKey", 4, "Second", "Child Node" ' the value 4 means "make it a child of node with key value "RootKey"
.Nodes("RootKey").Expanded = True
end with
</script>
</window>

It is important to use the correct class name in order to instantiate it. Also remember that the end-user (if you are going to distribute it) will need to be able to instantiate the control on their computer. Many controls when distributed do not allow it to be created in a design environment.

Also don't forget you can instantiate DLLs in VBScript using the CreateObject method. example:

Dim objFSO
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")

If you need specific help on something please let me know and I will do my best to help you.

Thanks guys. I was able to get a simple Hello World program going with the MS Rich Text box now that I pulled the correct name of the control right out of the registry (the OCX is richtx32.ocx).

<window name="main">
<activex name='test' align='client' classname='RichText.RichTextCtrl.1'/>
<script>
test.text = "hello world"
</script>
</window>

An error message on a failed load of a control might be a nice thing to add.

I'll look for the help on global variables- I know about CreateObject, but didn't know that using "Dim" within a script segment would make the object global and persistent for the rest of the zApp session.
