executing vbscript codes twice

TheMSsForum.com: The Microsoft Software Forum

The vbscript code is executed twice when I click the print button to print
some text after invoking ms word. I assume that I need to write some code so
that the code that invoke ms word, etc, would not be executed at the load
time, but execute only when the button is clicked. I am having onclick
routine in the header script tag. What could be the condition and codes I
need to put it so that vbscript would be executed only once?

Thanks

will be easier to help if you post a copy of the code.

I simplified the version enough to have the msgbox being executed twice.

Thanks
Daniel

<html>
<head>
<title></title>
<SCRIPT LANGUAGE="VBScript">
<!--
Sub Print_onClick
MsgBox "Hi!"
End Sub
// -->
</SCRIPT>
</head>
<FORM name="test">
<INPUT type="BUTTON" value="Print" name="Print" onClick="Print_onClick" >
</form>
</html>

Sub window_onLoad

End Sub

This should prevent the execution of code when the page initially
opens. Then when you click the print button, you should get your
MsgBox.

Then I tested it and it still opened it twice. To make it open only
once, I changed both places from Print_onClick to Printme.

For example

<html>
<head>
<title></title>
<SCRIPT LANGUAGE="VBScript">

Sub window_onLoad

End Sub

Sub Printme
MsgBox "Hi!"
End Sub
// -->
</SCRIPT>
</head>
<FORM name="test">
<INPUT type="BUTTON" value="Print" name="Print"
onClick="Printme" >
</form>
</html>

I'm guessing it has something to do with being called onClick...

Good experimentation catch. Alex Angelopoulos explains the cause in this
thread:

Because the onclick event for the object named 'Button' is being connected
to the same handler twice...

In client side VBScript, sub/functions with names in the form
objectname_eventname automatically connect the object's event to the handler
for you based entirely on the sub/function name. That's the implicit
connection.

You are also coding onClick="Print_onClick" to connect the event to the
handler. That's the explicit connection.

Either (A) change the handler's name and the onclick attribute assignment to
avoid the duplication (e.g., Sub PrintOnClick and onclick="PrintOnClick ")
or (B) drop the explicit onClick="Print_onClick" attribte assignment.

For clarity, I prefer explicit over implicit connections, so...

Sub PrintOnClick
...
End Sub

and ...

onclick="vbscript:Call PrintOnClick()"

is the way *I* would code this.
