Hey there,
Is it possible to use a link or Javascript as a ‘link’ to communicate with my web app using the PageSource control.
For example:
<a href="xojoapp:Method1"</a>
Thanks

Closest thing would be using the href tag to change the hashtag then detecting that and doing something.
You could use a query string and parse it:
<a href="xojoapp?Method1"</a>

Thanks how is this done?
Dim Session as Session = Session // Thom once said that if Session is to be called multiple times this will speed it up.
If Session.URLParameterExists("test") Then
MsgBox Session.URLParameter("test")
End If
Example:
<a href="xojoapp.cgi?test=hello%20world"</a> // < cgi
You really should write that more sensibly like
Dim aSession as Session = Session
I’ve seen this style in a few places & quite honestly it can cause you problems (fortunately not very often but when it does you’re really puzzled) and makes for hard to trace & hard to read code and some odd bugs.
To illustrate one of the issues
Dim Session as Session = Session
call Session // this won't compile despite there being a "Session" method - the local hides it
or
dim session as Session = Session
if Session(Session) = session then
// is this if cast(local) = local ?
// or a cast(function call) = function call ?
// or a potential subscript operation on the session local variable?
// or what ???????
end if
Later in your code you have to read in detail and knowing how the compiler resolves the names to be sure if Session is a local, a method or a type and it ail entirely depend on the usage.
You can’t just “read the code” and know from usage
Why do that to yourself ?
So don’t
Thanx Norman!
You learn something every day

Thanks all.

I had to ask Joe (the compiler guy) how that one would resolve & HE had to guess (then go look at the code)
If HE can’t tell me off the top of your head then its probably not a good idea to do it
What event handler should I be using and what code for hashtag links? Thanks
In HTML, hash tag links # are meant to position the page at a given scroll position. What do you want to obtain ?
