Simple and elegant, excellent idea Rolf!

It seems to me that if a cluster has unnamed elements, like in a slider with multiple sliders, it should still attempt to create a viable ini representation.  Has anyone considered this yet?

As predicted, I was doing something stupid.  What looked like a fired user event was really something entirely different and explainable.  Thanks anyway for your sobering "this sinmply cannot be true" reality check

I have two identical vi's (app1 and app2) that both create a user event and register that event in a event structure.  I have confirmed that each vi generates a unique User Event and Registration Refnum.  I am finding that a triggered user event in app1 seems to also be received in app2.  How is this possible?  I am pretty certain that I must be doing something completely stupid but right now I cannot see it.  Any thoughts would be very much appreciated.  BTW this is LV 13.0f2

Yeah same here, blocked...

Did you run devcon.exe with the 'restart' switch?

You can use a window utility called devcon.exe to restart a USB port.  That might force LabVIEW to refresh its VISA driver.  You can programmatically call devcon with the system exec.vi

Ok I am going to update to vipm 2014...

Rats!...vipm 2014 update is freezing up at the 'Checking for a newer version' dialog

Maybe I need to manually uninstall vipm 2013 first?

The latest task manager vip did not load on vipm 2013.  I have LV2013 and 2010 on my machine

0MG, nanomsg... Now that would make an interesting VIShots episode.

Here is a demo of cluster to SQLite.  It uses the 'other' SQLite toolkit

As an aside, I think the Import Web Service Wizard could be an amazing tool to help facilitate using LabVIEW to interoperate with the rest of the modern web based world.  For some reason there are very few (none?) use case examples to be found.   Maybe because its so hidden in the tools menu nobody knows about it or like me forgot how to find it again.

This might help with the login part...

or maybe you can get the salesforce WSDL and use the LabVIEW Import Web Service Wizard

I had this brainy idea the other day to help a customer create an event scheduler by using google calendar to manage the events.  I could setup the events to send notifications (email or SMS?) to my app which would then decode a command embedded in the event description field.  The other possibility would be use the google calendar web services to poll for upcoming events.  Notifiction by email at first sounds good but then I still have to essentially poll an email server. 

Anybody ever tried to do something like this before?

Can you use the strings[] property of the combo box to change the list to reflect the items still available to select?

Unfortunately the native sound card library does not include a way to poll for the buffer pointer.  You can get the 'is playing' status but that would probably not avoid glitching.

I think the correct way to do this is with a ring buffer scheme.

You might have better luck with this library since it can assign multiple output buffers...

You might look into this library...

All - thank you for the great replies!  I think I was just saved from a serious potential error in judgement. I am now settled on changing my original attempt at a fixed price contract to a much simpler consulting by the hour approach.  I have tried to offer a best estimate of the hours required but a large body of inherited software that is unfinished and untested has too many uncertainties for me to be held accountable.

You are the third person in a row to tell me that.  But sometimes one must try to balance risk with the need to keep work coming in.

I am in the process of formalizing a contract with a company that has been known to have had prior issues with LabVIEW developers and has adopted a tough talking somewhat litigious tone.  I am considering what wording I should put into a Software Development Contract that will protect me from any liability in the event a bug in the software should damage the clients property.  Has anyone had experience with this?  Or perhaps could suggest a contract template to start off with.

Been down this road and after fighting with the 3D graph and 2D picture control I became dismayed at LV's lack of modern 2D graphics with basic features such as anti-aliasing and the ability to define a hierarchy of graphic objects.  I was hoping someone would have tried to bring some SVG action in LV but instead had to settle for .net which is actually pretty nice.  I spent about 2 solid weeks wrapping .net graphics and produced some very nice anti-aliased radar type graphics. If interested I will try to wrap up my .net libraries and post in the CR. In the meantime you can see some of the results in my portfolio at www.viScience.com (Avionics 1553 Simulator)

Just poking this thread to see if anyone is still working on AMQP or 0MQ...

Here is a discussion on the subject...

Just curious, can you use the remote app ref to get 'All VIs in Memory'
