Hello, friends,
A very simple code as follows, but got an error: Microsoft JScript runtime
error: 'BHnz1' is undefined.
Any ideas? Thanks a lot.
-----------------
<body MS_POSITIONING="GridLayout" onload="initCOMComponent();" >
<form id="Form1" method="post" runat="server">
<OBJECT id="BHnz1" name="BHnz1" style="Z-INDEX: 101; LEFT: 136px; TOP:
64px" classid="clsid:60EB3120-469D-5E79-839D-AB53DA2DF932"
VIEWASTEXT>
<PARAM NAME="_ExtentX" VALUE="8625">
<PARAM NAME="_ExtentY" VALUE="9155">
</OBJECT>
</form>
<script language="javascript">
function initCOMComponent()
{
BHnz1.GetBinaryDataFile("test.dat");
}
</script>
</body> 9  1197 
It appears that the client side object BHnz1 was unable to be instantiated.
There could be many reasons depending on what BHnz1 is, but my first guesses
would be a security related issue or the component cannot be found.

I hope this helps,

If you are using Visual Studio 2005 for this then check the source code
that is being generated on the client. My guess is that the id might be
getting some other text added to it. Sometimes you might see your server
side id go from BHnz1 to something like CTL001_BHNz1. If something like
this is happening then you would need to update your javascript to reference
that. Can you post the html from View... Source from the web browser.

Does it make a difference if you try to call your method by using
Form1.GetElementById("BHnz1") instead of just BHnz1? Just an idea. Good
luck.
nope...

Is this an ActiveX component you're trying to instantiate? What does it do?

there are several issues hwne using com objects in the browser.
1) the object is not available for reference until form load (client side)
2) at form load the object is available, but may not actualy loaded. you
need to check readyState before accessing any properties.
3) the active/x control must be marked safe for scripting, or the browser
will not load.
try:
function initCOMComponent()
{
// test if browser allows creating of object
var o = document.getElementById("BHnz1");
if (o == null)
{
alert("this page requires you to install and trust the active/x
control 'xyz'");
return;
}
// spin until com object initialized
if (o.readyState != 4)
{
window.setTimeout("initCOMComponent()",10);
return;
}
// call methods
o.GetBinaryDataFile("test.dat");
}

Thanks. but, how to mark the active/x control as safe for scripting?
