Hi there,

This may be a little late but I wrote a blog post regarding the use of a HAL (Hardware Abstraction Layer) inside a QMH. OK, it's our own flavour of QMH which we call the DQMH but the post content is still valid for your use case. In addition the example I use is based around a Power Supply;

Here's the link

Hope it's useful

Using the ActiveX API can yield some odd behaviour if you then "manually" interact with Excel, launching another instance for example. 

If you have long running tests then I suggest that streaming to Excel is not ideal. Might be better to write to a database or TDMS file and then arrange for the data to be exported in an appropriate manner. Remember there are size limitations to the number of rows you can have depending on your Excel version, again worth consideration.

All that being said, if I can help with the Excel API then just ask

Jeremy,

It was great to see you again and a pleasure to meet your wife. She's probably pre-registered for next year already. She looked like she was having an awesome time.

We'd love to have you over for the European CLA summit next year !! You guys should visit Europe.

Failing that, see you at NI Week 2015 :-)

Chris

Thank you Mark. As always the LabVIEW community who could not attend any (or all) of the sessions are in debt to you for your efforts. Many thanks.

PS. Great to see you !

I believe that LabVIEW checks for the presence of a configured license server before querying for locally installed licenses, perhaps this is the cause of the registry queries ? 

Hi Vivu,

I've had similar issues in the past and whilst I do not have a concrete solution for you I do have some suggestions that have worked for me.

Just to chip in here, I recently had the same problem (2013 SP1). Bundling in a "variable" wire did not cause the class output "cluster" to be updated. Bundling in a constant (in this instance it was a string) did cause the "cluster" to be updated correctly.

 

Probably entirely related, editing some code in this class would cause the IDE to hard-crash, so I figure I just managed to get my code in a state that was not consistent.

 

I fixed my problem by deleting the VI that caused the crash and re-creating it from scratch. I think the inconsistency happened when I renamed a class VI to something that had previously existed in that class.

Eeesh Neil,

Did you ever get to the bottom of this or just re-create and move on. I've got the same issue here this morning (least I think it's the same). Constant bundled in updates the cluster, wiring in a "variable" does not. Probed the wire, input data is valid. 

Re built the VI and moved on. I had seen crashes too when making changes to the class so perhaps like you we've managed to upset LabVIEW.

I'm moving on the next issue but this is leaving me with a prickly sensation on the back of my neck, all is not well somewhere.

I have checked the string in the windows explorer the path works ok. C:UsersconorDesktopLabview DemosDatabase GeneratorImagesFilm3 that is the current path but when its read from the database it puts in those extra symbols.The string is stored as a varchar(max) in the database to hold the paths to the images. 

If you change the data type of this field in the database to nvarchar(max) do you still get the same issue ? 

If you set a field to be varchar(x) then the string stored there will be x in length even if the string originally stored was shorter. When you query the database you will get back a string of length x. Using nvarchar will store a variable length string up to length x.

Hi,

I have done several things over the past 10 years at various organisations where I have worked.

1. I've created my own SQL based storage framework (codeless storage using a custom process model)

2. I've purchased commercial test data management and analysis tools

3. I've used the default storage schema s

All have their own relative merits and drawbacks. PM me if you want any specific information about the tools I've used.

PSY may have just been de-throned !!!

Awesome summit, thanks to all of you who were able to be there and contribute to this awesome event.

All of the slides from the community day with the exceptions of Jim Kiring's (they're coming soon) are now posted on the CLA Community page at https://decibel.ni.com/content/groups/certified-labview-architects?view=documents

Looking forward to NI Week, hope to see many of you there !

Jeremy,

What's your current SCC tool ? Are there specific issues that are forcing you to look to replacing it ?

I have used a combination of VSS and Subversion over the past 4 years however Jack Dunaway convinced me to take a look at GitHub during the CLA Summit in Austin and so far my experience has been all positive. 

I was looking for a hosted solution with a nice interface.

Actually, Mr. SmartyPants, they're Taiwanese. Which, in some circles, is considered Chinese Taipei. So, although not quite correct, I was (geographically) closer. BAM! You just got owned! Yeah, that's how I roll. Tru dat, boy howdy. Word.

Check you

Can't speak - too awesome! Wait, is that Kim Jong Un?

This is totally my favorite Chinese group at the moment - I picked up a CD when I was in Donguan a few months ago. FWIW: My 2 year old son loves them too

Aren't they Korean ? They are my favourite Korean group right now !

Loving the "horse dance" as my boy calls it. I'm out on the town on saturday, is it enough time to perfect the moves ?

Reminds me of the time I first watched the following dance

(The guys expression at 0:40 is priceless)

The funny thing is that its a remarkably accurate recreation of most clubs in Cardiff (Wales) !

Hang on a second. The University of Southampton is just 12 miles from my house, I hope this doesn't end up like Fracking.

Maybe it's time to move..........

That's great Mark, thank you for taking the time to do this.

Hi

So thanks to a very very kind "insider" I am in a position to offer a very rare door prize to a lucky LAVA BBQ attendee: a LabVIEW iPhone hard plastic cover. This is for a 3G / 3GS model.

Cheers

Chris Roebuck

CLA , CTA and all round nice guy

I just bought mine ! !

Can't wait

A little rule I always apply in situations like this is to remember that "people always criticise things they don't fully underatand"

I've spent 14 years programming in labVIEW , it was my first language , it is my go-to language (ecuse the pun) and it makes me more productive. I'm happy

EDIT: Just read Dave's response, it makes me optimisic to know that guys like Dave and AQ are driving the direction of this product. Great reponse.

Really good job. I have read several whitepapers written by you in the past and like your style. I'm off to dig aorund the example code so may be back with questions as I'm a hopeless in the kitchen.

Actually count me and my fellow brit Mr Steve Watts in.....

Count me in !
