    Hidden editable pixmap control

    Well in playing around with the control I crashed LabVIEW so I'd say this was something that shouldn't be messed with, but pretty neat and something I didn't know existed.
  2. Yeah something like that. The password replacement code I think is still posted online in PHP. I wrote the G equivalent and posted the read-only parts online. It has some pretty useful thing like being able to read information about a VI without VI Server. At one point I was able to figure out what objects are on the front panel and block diagram by looking at the raw VI file. Of course doing this means you don't get the satisfaction of knowing what the password was.

    Where's the manual?

    I doubt there is any documentation beyond the help included with installing the OpenG packages. If you open the context help on any VI it should show a description of the VI and what it does and how to use it. This isn't always enough documentation on understanding how a thing works, but the source code is fully there too, so understanding it should be possible if the documentation provided isn't sufficient. The OpenG website itself went into disrepair and had spammers taking it over so OpenG discussions were moved here to LAVA.
  4. Yeah I used to have a list of the passwords I had reversed but I can't find it at the moment. I think there was something about Looking Glass , Jack Black, Jabber Wocky, Axes Of Eval, FP Rocks, and a few others that were random characters and harder to remember. I (probably like you) wrote code to go over the most common word lists for words of 5 characters or more, and for 1-4 I just brute forced all combinations, then after that used a program to reverse MD5s using your GPU. It was slow, painful and each new version of LabVIEW added more and removed some. I bet with the advent of new graphics cards this process could be made easier. There is a method in LabVIEW to add known passwords to a cache, and then not prompt if they have been entered so I thought it would be a neat VI to just run which would make looking at all NI VIs easier rather than writing code to replace and remove the passwords thereby changing the VI which I don't like. Maybe we could make that VI, and then password protect it?

    Display video in Labview

    I've done this in the past by leveraging the PictureBox .NET component and VLC. Just have VLC installed which is the same bitness as LabVIEW. Drop a .NET PictureBox and then use some of the code found here, which calls into the VLC DLLs to open a stream and display it. Here is another example that I think works too.
  6. Yup State Machines. They aren't the solution to all things but do worlds to organizing your code and for readability. You can create one single BFC (large cluster) that is in a shift register with the things you want to read and write to like variables. Except you know where these variables are being read and written to, and you have state order to ensure one thing happens after another. Once your code gets so large that a state machine can't help you, you should learn about actor based software designs. Not necessarily NI's Actor Framework but actors in general. Independent parallel running loops that do dedicated tasks. This helps modularize your software so all the File IO stuff is handled in one place, and all your DAQ stuff is handled in another, and all your UI stuff is in another. Breaking up larger problems into smaller more manageable ones is something LabVIEW is good at.

    Wiki Account Frustration

    Most Brians I've met are pretty cool, but those shifty Bryans on the other hand I wouldn't be to sure about.

    LabVIEW 2017 Editing Issues

    I noticed some of your VIs were missing and showing a placeholder icon. I'm guessing as selections are made or scrolling happens, NI is constantly checking for things and the larger the VI the larger the delay, but also the more things it needs to check which are missing the longer the delay. Of course NI could optimize it and they likely have for most cases, but what you are seeing is probably an issue they didn't test for, or tested for but not in as extreme case as yours. This is all of course just a guess, but it is based on other IDE performance issues I've seen in the past relating to NI checking for what things need to be recompiled and what things don't. If you can send the VI to NI I'm sure they would appreciate it, and by extension the rest of us who happen to have to deal with that too.

    not receiving notifications

    Well I got the email that a report was submitted for me. And I got an email about a private message earlier this week. Those are the only things I have setup to email me. I'll ping Michael to see if there is anything he can do.
  10. You're welcome to use whatever license you want, but for LabVIEW we see lots of people use BSD for the kind of "I don't really care, just have this and I'm not responsible, and leave any attributes I have in the source" kind of thing. Obviously that is oversimplifying it. Here is a thread on LAVA.
  11. It should say "with locked diagrams you can't fix the problem without potentially breaking licensing, violating IP, or violating ethics". Yes that site, along with the method of signing VIs is semi-known.
  12. I usually spend a minute or two on the look of my wire but just so it doesn't look like all the other ones. This tool could be handy in making sure they look unique. Does a randomize button make sense? Or does random patterns just look like garbage? The NI GOOP Development toolkit has a random button for wire appearance, and icon appearance. A lot of time I will click the random button until something is close to what I want, and then I'll adjust things a bit more. It might be a good idea to have something similar in this. Actually it might be even better if this were added to that toolkit...

    Need help creating Candy Crush type of game.

    How much LabVIEW do you know? I'll admit that some of altenbach's code is using some techniques I wouldn't have thought of, but simply posting his VI and saying you are stuck gives me the impression you don't have much training. I'd recommend taking a bunch of the free LabVIEW training that is online, and then I'd recommend you start over with your own design. As for your specific question I'd say the solution is to have a conditional check (case structure) around the part of the code doing the swapping, and only perform the swap if the second click, is one move away from the first click. At the moment you aren't keeping track of what the first click is so you'll need to do that so the second click can be checked.
  14. Nope, at the moment the progress bar is an indicator only. It can be value only, which will use the web control made in javascript so the appearance will be slightly different, but there is no way at the moment to interact with it. If you understand JS better than me, then you could probably add the control functionality. As for the background image I've never had a need for that, but I can see that it might be useful. One option might be to just place a 2D picture control behind all other controls on the front panel, and load it with an image. It should default to Image Only mode, and if I did the Z order stuff properly it should work, but to be clear I never tried using that control.
  15. If you prefer the reverse I made some code here that modernizes a front panel and attempts to replace all controls with the modern equivalent which I prefer for front panels not typically seen by the user.
