It seems DocumentText returns the source code of the page.
You should use JavaScript to get properties and values of the HTML forms.

Example:
B4X: 
<html>
<head>
<script type="text/javascript">
function getValue()
{
alert(document.getElementById("text1").value);
alert(document.getElementById("check1").checked);
}
</script>
</head>
<body>

<form>
<input type="text" id="text1" value="Type me" />
<input type="checkbox" id="check1" value="Check me" checked/>
<input type="button" id="button1" onclick="getValue()" value="Show value" />
</form>

</body>
</html>

"Document.getElementById("text1").value" gets the current value of the text box.
"Document.getElementById("check1").checked" gets the current state of the checkbox
Try to do some additional research

I think the only way to do this is to write the values to a file, and then read the file from your application.

For example:
B4X: 
<html>
<head>
<script type="text/javascript">
function getValue()
{
var fso = new ActiveXObject("Scripting.FileSystemObject");
var FileObject = fso.OpenTextFile("Test.txt", 8, true,0);
FileObject.write(document.getElementById("text1").value)
FileObject.close()
}
</script>
</head>
<body>

<form>
<input type="text" id="text1" value="Type me" />
<input type="checkbox" id="check1" value="Check me" checked/>
<input type="button" id="button1" onclick="getValue()" value="Show value" />
</form>

</body>
</html>

This will write the text in the textbox to the file Test.txt.
Read the file with your application to get the values.

NOTE: This example will only work with Internet Explorer, Since it uses an ActiveX object.
I'm not sure if Agrahams WebBrowser control allows ActiveX, but you should give it a shot

That is a correct assumption.

"Document.getElementById("text1").value" gets the current value of the text box.

This is already implemented in the WebBrowserEX Dll, in wich it is possible to eithet get/set the value of a give control, either by name or by ID...
"Document.getElementById("check1").checked" gets the current state of the checkbox

This is Not implemented im my WebBrowserEX, as I only added the "I need this" features in it, and no user ever asked for it...
Still it would be far more easy to simply scout the documenttext, for the given control changes, than to include a get method for every control type.

Sorry Cableguy, I thaught Agraham made get WebBrowser library.
I must have confused it with the htmlPanel.

I'm not sure I follow. The way I see it Javascript is the only way to get properties

I did! WebBrowser runs on both device and desktop and as such offers strictly only the capabilities supported on the device.

Cableguy took the WebBrowser source code and added some desktop only capabilities to produce WebBrowserEx that will only run on the desktop.

webbrowser very convenient control and to use it as the interface of the program it would be healthy!

This is so confusing. Why don't you just combine all the WebBrowsers into one super-browser library?
I'm waiting for it

Because it is just not possible! If you want a WebBrowser to run on the device then the WebBrowser library does all that a device supports and will run on the desktop as a bonus.

If you want the extra capabilities that a desktop can offer then WebBrowserEx offers some of them but because those capabilitie are not present on the device WebBrowserEx will not run on the device. Period!
