VB6: ActiveX DLL events in a web page?
I've already asked this question, but it's not showing up in the Visual Basic Topic Area! Arrg. Anyway, here's a duplicate. I hope this one shows up.
How can I respond to my objects events in a web page? That is a very open ended question, so I'll be much more specific with an example below?
Create the text file "example.hta" and paste the following:
------------- example.hta start ---------------
<!-- frames -->
<html>
<head>
<HTA:APPLICATION
ID="oMyApp"
VERSION="1.0"
CAPTION="yes"
MAXIMIZEBUTTON="yes"
MINIMIZEBUTTON="yes"
SHOWINTASKBAR="yes"
SINGLEINSTANCE="yes"
SYSMENU="yes"
VERSION="1.0"
SCROLL="no">
<title>Hello World Example</title>
<script language="VBScript">
Dim myVar
set myVar = CreateObject("pjtHelloWorl d.classHel loWorld")
sub myVar_listenUP(theMessage)
inComing.innerText = theMessage
end sub
sub saySomething()
myVar.sayHello
end sub
sub getObjectVersion()
versionNumber.innertext = myVar.getVersion
end sub
</script>
</head>
<body>
<h1 onclick="getObjectVersion( )">Hello World Program - The Beginning (version <span id=versionNumber></span>)< /h1>
<div id=inComing onclick="saySomething()">c lick me</div>
</body>
</html>
------------- example.hta end ---------------
Now, make a new project in VB 6. Make it an Active-X Dll project. Name your project "pjtHelloWorld" and name the class file "classHelloWorld". Open the code window for your class and enter the following code:
------------- classHelloWorld code begin --------------
Public Event listenUp(ByVal message As String)
Public Property Get getVersion() As String
getVersion = App.Major & "." & App.Minor & "." & App.Revision
End Property
Public Sub sayHello()
RaiseEvent listenUp("Hello World")
End Sub
------------- classHelloWorld code end --------------
Save your project. Make pjtHelloWorld.dll. Double-click example.hta to run it.
If you click on the title anywhere, you'll see the version number pop in. The HelloWorld object is being instantiated, and the property is properly fetched when wanted.
Now click the text that says "click me". Nothing happens. Why? I can't figure out how to respond to events that I raise from my active-x dll project in the web page.
Please alter my example such that you can respond to the events from the HTA for the points.
Thanks in advance for your help.

If anyone is interested, it turns out that I couldn't find a way to do it with an ActiveX DLL. Instead, I compiled my functionality into an ActiveX OCX control that has no visible interface. This allows you to use an
object tag like the following:
<object
id="myOCX"
classid="CLSID:7A97D874-3C
width="1"
height="1">
</object>
Having this tag available when you load the page into the browser's memory allows it to hook the events together. So, in my VBScript, I could respond to the event "myEvent" like so:
sub myOCX_myEvent(parameters)
' respond here
end sub
