Hi,
I have to pass a lot of variables from vb.net to javascript using client
callback. the problem is that there are single variables, but also arrays
with differents indexes.
I have two questions:
1) is this technology made for passing a lot of variables or in fact only
for one?
2) does it exist a esier way to pass the values and to recover them in
javascript?
Thanks for advice.
André
So far i did this:
Vb.net:
Dim pcbez, uurbez, logonbez, tpebez, htoebez, hlokbez
ret = recbezet & "," & recuur2 ' single variable
pcbez = Join(pcbezet, ",") ' array index=10
uurbez = Join(uur, ",") ' array index=10
logonbez = Join(logon, ",") ' array index=10
tpebez = Join(tpe, ",") ' array index=10
htoebez = Join(htoe, ",") ' array index=5
hlokbez = Join(hlok, ",") ' array index=5
returnValue = ret & "," & pcbez & uurbez & logonbez & tpebez & htoebez &
hlokbez
Javascript
function ReceiveServerDa ta(rValue)
{
recbezet=rValue .substring(0,1)
recuur2=rValue. substring(2,3)
....
}

You can only pass back one value, so concatenating them together and then
splitting them apart again on the other end is the standard solution. It
looks like you're pretty much doing that already so I don't have any
complaints.
Here's an example I put together: http://SteveOrr.net/articles/WebChat.aspx

Hi folks,
I would be interested to hear peoples views on whether or not 'pass by
reference' is allowed when using a Web Service method.
The thing that troubles me about pass-by-reference into a WebService is that
essentially we are passing an address of an object which resides on the
'local machine' i.e. a local machine object address. Surely when the
WebService method is called and run 'on the server', the reference type will

How to pass an object to a function/method call in C# that will
guarantee not to change the object?* In C++, as seen below, you can
use the 'const' keyword in the function / method declaration. But how
to do this in C#?
