Re: Application Interface Options for Integration
If I were the source system vendor I would be implementing webhooks if I cared at all about integration of my application. http://www.entechsolutions.com/hooks-and-sockets-for-web-apps If I were you I would be asking for webhooks. But, maybe, that's just me. I would probably also look at using ZeroMQ if I were going to create middleware for disparate clients.

public void Init()

RecursivelyAddEvent(this.Controls, 0);

public void RecursivelyAddEvent(ControlCollection controls, int level)

foreach(Control ctrl in controls)

We have just found that if there are multiple network cards in the machine

listeners get nothing. I’m not sure how to code a fix for this. Do I need to
do this to get an IPAddress array and then put them all into the Send call?
Like this...?
string hostname = Dns.GetHostName();
IPHostEntry he = Dns.GetHostByName(hostname);
foreach (IPAddress addr in he.AddressList)
{
// Send with an endpoint set to each addr instead of
IPAddress.Broadcast?

I’m not sure if this is the correct technique. Any sockets boffins here know
this sort of thing?

Re: [OT] VBScript return string runtime error
I believe that wrapping a parameter in parentheses forces it to be passed ByVal - even if you've coded ByRef. And, in VBScript, everything is a Variant (not quite the same thing as an Object) - so you may have to use CVar occasionally.

I'm not sure of the actual cause but your fix is: id = client.SendRequest((request)) because the working client.SendRequest(request) is really client.SendRequest (request) or Call client.SendRequest((request)). The call corresponding to the original id = line Call client.SendRequest(request) or client.SendRequest request fails with TypeMismatch for me. I assume the problem is VBScript only deals with Objects most of the time, and so doesn't like the original accurate type being passed to the (correct) accurate type, but the () returns the object to Object, which it doesn't mind passing anywhere. -- Regards, Mark Hurd, B.Sc.(Ma.)(Hons.)

I came across Sage http://sagemath.org/ the other day. It's trying to be an open source alternative to programs like Mathematica - using Python to glue together a collection of libraries. It's been about 15 years since I last played with any mathematical software - in a previous life as a maths teacher - so I can't help further.

There are some things that require a bit of getting used to, but it seems like it's the most used and programmable. We've got Maple at Uni as well, and I certainly prefer that for entering and manipulating equations. I haven't done much with Mathematica, and those are the only programs I'm familiar with. I'm under the impression that a component of the scientific community uses Python; but I suspect that's only because it's more accessible to them than other programming languages (and probably due to some existing math libraries which make things easier). Anyone have any thoughts on the matter? I believe MATLAB has some sort of interaction with Amazon EC2 for running distributed items, which seems very cool, but I'm yet to do anything anywhere near as interesting as requiring that. Interested to hear if anyone has done any work/investigation in this area. -- silky Every morning when I wake up, I experience an exquisite joy — the joy of being this signature.
