Is your stand alone app (exe) a console app or a GUI?

I remembered this post on the dark side...

Any person with programming experience can laugh at this.

Only a LabVIEW programmer would laugh at this...

Jim's magical use of the word open is important. The upper image is "open". Practically any programmer can read and interpret it. It can be compiled and adapted to run on virtually any type of computing platform.

The lower image can only be created and executed with a specific programming language.

I was curious, tried it and it works ... created a subvi, cleared the icon and placed it on my block diagram. Invisible code! You could ruin a team member's day with something like that.

Ah, this reminded me of this http://forums.lavag.org/Small-icons-t6689.html' target="_blank">Small Icons thread...

Ex-Fannie Mae worker charged with planting computer virus

Original Criminal Complaint (contains details, .pdf format)

QUOTE

The malicious code was hidden after a blank page, and “it was only by chance” that the senior engineer scrolled down and found the virus.

With LabVIEW, it's as simple as placing the malicious code under a structure, or "off in the buckwheat" (far off from the active code portion of the block diagram).

You have to do the same thing as the guy who found this; look carefully at the scroll bars or run the code through a beautifier. If you need to justify an upgrade to 8.6 and work in a secure computing environment, 'clean up block diagram' and VI Analyzer are good reasons. Just remember you have to use them

(Whether 'clean up block diagram' actually 'beautifies' your code is another story. Beauty is in the eyes of the beholder...)

See the LabVIEW 8.6 Upgrade Notes, page 28.

Private items are properties/methods/events that are not fully debugged by NI and most likely will be released in a future version of LabVIEW.

And http://forums.ni.com/ni/board/message?board.id=170&message.id=381343#M381343' target="_blank">this post on the dark-side is one good reason to limit the amount of items exposed.

I have a hard enough time keeping track of the public methods and properties. Don't even get me started on calling .NET properties and methods; I get depressed when I have to poke around in THAT huge pile of, um, 'stuff'.

I was right.

Bush and Obama did not say that 98% of population is at animal level.

They also didn't say that the moon is made of green cheese...

I went to Dunkin' Donuts this morning, and I ordered a sausage, egg and cheese sandwich on a sesame bagel. The cheese was not green, but the bagel was not sesame; it was cinnamon-raisin. I ate it (yuck) while entering a comment on the DD web site. When I pressed the 'Submit' button, I got a polite error and the complaint I entered was 'lost'.

This particular Dunkin' Donuts CONSISTENTLY messes up my order. Are the employees just animals who like to torture me? Does DD take my complaint (including name and address) and pass it to the secret police for survailence?

Could it be that I am at fault for not finding a place that provides the satisfaction (physical and emotional) that I desire? I am responsible for my own happiness, and must make it where I can. It is not the responsibility of the world to understand or conform to me. It is my responsibility to 'fit in' as best I can and to share my beliefs where and when I feel they can make a difference.

F*ck DD, the http://en.wikipedia.org/wiki/Pain_au_chocolat' rel='nofollow' target="_blank">pain au chocolat at Panera is better, and the price is almost the same

I had a similar problem to this several years ago.

My database grew so fast and then ran so slow that I ended up storing the data as a file in a shared location and stored a path to the file in the database.

If your database is providing some sort of security for the BLOB data, this might create an administrative issue (matching up OS and DB permissions) but I think you will find that the file method scales much better and will cost less hardware-wise in the long run.

thanks for that, the for loop works fine, the program is sending the first 5002 iperf command and then it waits for it to complete before it sends the next one, how can it keep sending the iperf command without waiting for the previous one to finish.

let me know if u want anymore clarification on the problem

Why would you want to run http://en.wikipedia.org/wiki/Iperf' rel='nofollow' target="_blank">iperf multiple times in parallel?

Wouldn't that make the performance numbers for each test invalid!?

(Edit: look at using the iperf '-P' modifier)

Here is a VI that gets VI name, icon and description and puts these into a picture control.

I'm not sure it can be put into the help windows using functions from the Help palette or maybe by saving the picture into a file and feed the file into the windows but I think it's not really nice...

Looks good, I actually started working on something similar, then realized I would want to make an XControl that would take care of resizing the description like the NI context help. I realized I was going overboard, considering the tool I'm working on is a temporary one to help developers selectively compile VIs, LLBs or folders (without subfolders).

I even started to look at how to shrink and grow the parts of the image like the real thing. You can export the interface for the VI and then play around with the 'wisker' and terminal locations to replace the full name with an index and add the datatype info below when the window is made very narrow.

This is about as far as I got...

QUOTE (crelf @ Jan 9 2009, 02:33 PM)

I don't think you can get the context help window contents to update without loading the VI into memory. Here's something I used once to get the info of a subVI into the context help window:

Then the context help window will update when the user mouse-overs the Boolean. It's kind-of a hick, but it worked for the situation I was in back then.

This works fairly nice. ( see picture).

I wish there was an Application method or property that would allow me to set the object of the context help so that I could specify a VI from MY tree based browser (like the Project Window does)

So how to be sure we deal with an actual file/dir instead of a shortcut?

There are two types of shortcuts; lnk and url

Maybe my contribution to the Code Repository (Resolve Shortcut Path) will help ...

If you think about it, the tabs for the second and third rows would be covered when selecting the top row, hiding them and making them 'unselectable'?!.

Top 25 Most Dangerous Programming Mistakes

LabVIEW programmers aren't as concerned as others about the security aspect, but these same mistakes can break your code ...

• Improper Input Validation
  
• Race Condition
  
• Untrusted Search Path
  
• Improper Resource Shutdown or Release
  
• Improper Initialization
  

Apparently, this was a very convincing video!

Does anyone know if there is a vi.lib/ function, method, or property that can be accessed that will return the Context Help for a VI by file name? The file would not be loaded in memory, I want to supply the full path to the file only...

I want to create something similar to the way a project will show the Context Help for a VI when you hover over the name...

No, there are plenty of things the profiler won't report. I don't believe that shows global memory like queues and notifiers or stuff allocated by ActiveX nodes that you've invoked.

Creating an unlimited sized queue in LabVIEW (or in ANY programming language for that matter) is BAD MOJO!
