Capturing events of an ActiveX component in CVI5.01

[Daniel Bentolila]

Has anybody tried to capture an ActiveX component event in a CVI application
?

for example I've created a new instance of the Internet Explorer application
from the CVI , using the ActiveX Automation controler I choosed the Microsoft
internet controls then I selected IWebBrowser2 and the IWebBrowserEvents2
classes and generated the fp file for the CVI.
Under the the IWebBrowserEvents2 I see there are events fucntion for example
OnQuit, and I wanted my CVI app. to attach the quit event when the user closes
the IE window.
Now at this point I expected to find some mechanism that let me to install
some callback function where I can put my customised code to the quit event,
somehow I have to tell the IE to call
my function whenever the OnQuit callback
function is attached and I don't know how to do this.

Hi Daniel,
My answer may not be very helpful but capturing ActiveX control event in CVI
may not be an easy ( and practical) task. The ONLY known solution that I
believe is to create ActiveX container which CVI probably is yet not.

Hope this helps.

Daniel,

Have you tried the function CA_RegisterEventCallback function? (I am using
CVI 5.5)

This function is used by the functions generated by the Automation
Controller Instrument Driver Wizard.
It is not intended to be used directly.

It basically registers a callback for an ActiveX Automation server object
event.
To register the callback, you must specify the CAObjHandle of the server
object from which you want to receive events.

With CVI 5.5, there is an example for IE with Active X under the
samples/activeX directory.

Hope this helps,

Azucena

Thank you for you mail,

After I read this article

http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/610540bb3ea4ebdd862568960055e498?OpenDocument

I realized that ActiveX events are not supported on CVI 5.01 at all since
its introduced as a new feature of CVI 5.5
