}</pre>

please any help

HI,williamroma
First, from looking at your code i noticed that you use the pre tag. In order for a script to be executed it must be enclosed in tags.
Second, Javascript is case sensitive so the method getElementbyID will work only if it is written getElementById.
Third, += works welll for numbers, but for string you need something like string1=string1+string2.
Forth, all kinds of input work when they are placed inside a form tag, and for buttons you need to specify what happens when you click them using something like onclick.
heres a refined version of your code which worked for me:
<script language="Javascript">
var num=1;
function on(){
var div = document.getElementById('frm1');
div.innerHTML=div.innerHTML + "<input type='text' id='in'+num />";
}

hi,
I have tested the code in chrome, opera and IE 8,9.
seems to be working fine, except that in ie you need to enable activeX objects to make it work properly. Iv have done a little tinkering with it and here is the new version.
just copy it in ahtml file and give it a go!
var num=1;
function on(){
var div = document.getElementById('frm1');
div.innerHTML=div.innerHTML + "<input type='text' id='in'+num />";
num=num+1;
}
Best regards!

You cannot do that, and why would you want to.

Let me get this straight: you want to select lat an lon in your windows form and the using the GoogleMaps api open a webpage in your browser (probably google.maps) centered on that location?
Because if you do, my friend there is no way to do it. Javascript works inside the browser. Why dont you make a web app on a local web server (e.g apach on your system and create the form in there using html or php. then sent the selected data by query string.
If you want sent me some pseudocode for what you want to do and i see what i can offer.
They call me BPIS (Beastly Powerfull Immensly Stupid) and i let them.

I don't use the webbrowser control but it is my understanding it works just like IE, so you build a webpage that does what you want, deploy it with your windows app and then load the page into the webbrowser control. So, what part are you having trouble with?

Yes, I believe the following is somewhere in the core libraries.
function isJavaScriptEnabled()
{
return new Date().getDay() == 0

JavaScript goes in the head tag and not in the form tag.
