ASPX, VB .NET, JavaScript...all play nice?

[drozwood90]

So, to better integrate Google Voice with my wife's new phone, I am creating a webpage to allow her to kick off text messages. I have all the "grunt" stuff working.

I wanted to make a text box that had a charactor counter. I found some examples online. The one I chose was from http://www.obout.com/

Really awsome and most of their modules are free.

Anyway, to use their stuff, they provide a LOT of Java Script examples. after modifying my web.config file, placing their .dll into the \html\bin directory everything works with their examples.

So, now I have a button that makes a call to a Java Script function, which calls "alert". I get the popup message on BOTH my phone and any other web browser I have used.

I want to change that alert to call a Homeseer script. I have done this when running VB script in .asp pages.

As I see it, I have 2 issues:
1) I can't seem to figure out how to call any homeseer objects using Java Script

2) I tried to setup the Java Script to call a VB script...this does not seem to do anything, but also does not throw any errors. This script was supposed to just call hs.writelog.

I am not sure if the aspx page is goofing me up, or what. I wanted to go with ASPX so the page loads faster for us, as well as being .NET.

If it would help, I can post the webpage...it's a bit lengthy so I'd prefer not to...but if we end up needing it, I will post it.

Any help or ideas is appreciated. Thanks!

I know how to do it in VBScript, but not JavaScript, but the principles should be the same. If you can do a FORM POST from JS using the HTTP server object, then everything you need is there. Here's a VBScript example to run a HS event:

Set objHTTP = CreateObject("Microsoft.XMLHTTP") 
objHTTP.open "POST", "http://localhost:8000", False  
objHTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" 
objHTTP.send "run_event=My+Event" 

I know JS can talk HTTP since that's the underlying AJAX technology. It's just a matter of instantiating the HTTP object, then packaging the FORM fields up.

I might try and play with some JS later today too...

I had also read somewhere else that they have a lot of free components. I am interested in their treeview but I don't see anything that is free. It seems like everything is at least $99. How do you get a free version?

[drozwood90]

You just download the software.

http://www.obout.com/t2/index.aspx

There really are not that many of the components that are NOT free. If you get the suite, it'll have both the free stuff and NON-free stuff.

What I did, after I checked out the suite, was navigate DIRECTLY to what I wanted...for instance:
http://www.obout.com/show/

That STATES it is free. Just download and go. If what you want is not free...it'll be a bit harder to get anything but the demo (for instance the image manipulation stuff costs $).

Almost done rebuilding my server.

Man...LOTS of files...

Then I hope to get back to this. I hate being SO close, but without a working solution.

Rmason,

how would you pass in a variable? That's why I wanted to execute a script...I see how you can run an event...

I suppose, if there is a post for running a script, this will work, otherwise I need to try to figure out how to get a Java object of the HS server object...so I can use a runex command...

Thoughts?

Rupp, is there any examples of getting the hs object and using it in Java?

Thanks!

I don't think I saw the original post until now. I may be wrong, but I thought that normally JavaScript runs on the client. I.e., if you have a web page running on the phone that connects to the HS web server, whatever you run in JavaScript is actually running on the client browser, not on HS. As a result, you can't invoke an HS object, or at least not very easily.

If it were me and I needed to pass a variable, I would write a simple asp page on the HS server and pass the variables as name/value pairs on the URL. So, your client call would do something like:

http://myhomeseer/rcvr.asp?variable1...=somethingelse

Then, rcvr.asp, which lives on the HS server, would look something like:

<%@ Language=VBScript %>
<%
  hs.writeLog("rcvr.asp","variable1=" & Request.QueryString("variable1"))
hs.writeLog("rcvr.asp","variable2=" & Request.QueryString("variable2"))

%> 

That would be the quickest way to have a client pass some variable into HS. Once in rcvr.asp, you are running inside HS and have access to all of the HS scripting functions.

Correct - JavaScript != Java
If you are set on using JavaScript, then you would need to use the HTTP request object. You wouldnt be grabbing a reference to the HS object at all. I think it might be possible, but like you said, it would be difficult at best.

[drozwood90]

Thank you both!

Now that I understand java script is CLIENT only, I'm using an asp page (as the example was given) to pass values INTO HS. Looks like that was the missing link!!

Thanks again!!
