I'm trying to see if there's a way to use the display block in EV3 as a basic print function. I'm working from home and don't have a brick to test the code with so was hoping to just use the display preview option to output variables but I haven't been able to find a way. It will only show the standard 'Wired_1FAC2752-7229-46'. I've tried putting a wait block after it, putting it in a loop and clearing the display first but the preview never displays anything.
Thanks in advance
What about trying a "virtual" brick to run your programm?
Have a look at the "Virtual Robotics Toolkit": https://www.virtualroboticstoolkit.com/
It's not perfect and its not free but maybe a good workaround if you don't have any hardware at Home.

I have a scene that has 3 buttons, one for each level. I made buttons 2 and 3 uninteractable and I want to make it so when you win the 1st you can start the 2nd etc... So I have unchecked the interactable box from the options of button2. Then I went to the script of my player and I have connected the following parts so when he completes the 1st level the button 2 gets to be interactible. But there seems to be an issue.
(This answer only applies if you were loading new scenes.)
Perhaps, the problem is that you can’t save a variable telling which levels are allowed. (Unless you do it through, an actual save mechanic.) this is because unity destroys all objects in a scene when loading a new scene. This removes all data stored in variables. You could get around this from using
DontDestroyOnLoad(gameObject);
this saves the gameObect variable you put in the parentheses through scene loading. You can attach a script that would store the variables to this, to save information.
If you can’t figure out how to get the variables from other scripts, use this:
var newVariable = GameObjectVariable.GetComponent<scriptName>().variableName;
I see you were using visual coding, so if you can try and figure out how to find these methods in there, it should work.
If you want to use actual save mechanics, go to this link:

this is my very first entry here, may it not be the last....
I am having a bit of a struggle with some GUI stuff.
I really have an animation up front my eyes and it should look like the following: using c# with desktop application.
This Form looks like a login window with server address, username and pw textboxes and with a connect button as well, so nothing special. Size wise it can be small or at least same as size as the turned window. doesnt matter at the end.
once you entered your credentials and all turns out to be fine, connection is there and valid.
The main Form is suppost to flip then (doesnt matter horizontal or vertical),
and shows you your options you got then in this newly window. kind of an animated sign, that you are logged in and have now these options.
But the flip is suppost to stay on the same place. Like a card flip or a coin flip, but just the whole form and it ends then at the same place as before.
(sounds really wired to explain)
This can also be done with a new form poping up, just with a animated turn over, no problem with that.
And this is exactly where I am stuck.
I really cant find any information on how this would look like in code or even in animation.
I am using c# and the basic project started as a desktop application project, which it will be at the end.
Its been a while since my last coding, please be gentle.
i know there are plenty of entries in here also in google as well, but i didnt found anything which will do this for the main window as a total. images etc: yes, but for the whole form: no.
Any help out there?
May be tehr eis a trick i am not aware of? Its been a while since the last coding work, I need to admit that.#greyhairsarecomming
many thanks in advance! much appreciated
kind regards TG
I have a database that I work on using Access 2013, though I must maintain compatibility with Access 2010; I am using Windows 7.
I have an input form that is set to Pop Up = Yes, and Modal = No. When opening this input form directly from the Navigation Pane, it functions perfectly normally.
I have a macro in a search form that calls up this input form with the specified record using the "OpenForm" action. When opening the input form with this macro, the form's background is totally garbled (it pulls the background image from whatever was behind it when called, as though it were transparent), and all labels are unreadable.
That said, if I run the macro again by trying to open a different record, the form then appears correctly until it is closed. Also, if I change the "Window Mode" in the "OpenForm" action to "Dialog" rather than "Normal," it appears correctly.
Neither of these are valid solutions, though -- it should work on the first time, and I do not want the form to be modal. All my code seems okay (insomuch as I am not receiving error messages), so I don't understand why it would be doing this... any guidance is very much appreciated.
I have discovered what is causing this problem, though I don't understand why.
The macro I am using came from a sample database, and has some commands I am not fully familiar with. One such command is "Requery."
I experimented with removing various parts of the macro with the window mode as "Normal" for the "OpenForm" command. As soon as I tried removing "Requery" (and nothing else) the window opened in "Normal" mode with no distortion whatsoever.
In short, having "Requery" in the macro was what was causing this error to occur. It seems like an innocuous enough action (all it does is refresh data, from what I understand, as described here: https://msdn.microsoft.com/en-us/library/bb177360(v=office.12).aspx), but since I don't see why its inclusion was necessary anyway (if anyone could shed some light on that, it would be appreciated), it looks like this is essentially solved.
I hope this may help someone else in the future!
I have made a gui in MATLAB wherein I need the window to be fullscreen directly after I run the application. However, this does not happen so, and instead, a smaller window is generated, and as a result, the TABs that I have designed, look out of shape...

Suggest options as to what could be done in the code to get it to fullscreen like this:

Mathworks has provided some function for doing this: http://www.mathworks.co.uk/support/solutions/en/data/1-3MY8PN/index.html?solution=1-3MY8PN
You can resize the window to make it the size of the screen (though the window will not be "maximized"), without having to download extra files: http://www.mathworks.co.uk/support/solutions/en/data/1-4TEZ9X/index.html?product=SL&solution=1-4TEZ9X
There are lots of matlab examples online, so searching is highly recommended.
Is there a function that allow me to select text when the extension
stays open. Normally when I Use the extension popup and I Click outside the
extension the extension close. Is there a wat to avoid this.
Thank you so much
Unfortunately there is currently no way to keep the popup open once you focus out of it. This is by design.
If you would like to always show something while interacting with the page, perhaps the experimental Info bars or even Desktop Notifications would work?
Hope that helped!
The only way to keep it open is to right click over the extension icon (button) and select "Inspect popup" the extension popup then show up and remain open but of course the debugger window show and this not a fix obviously still it will maybe inspire a hack... if someone is skilled enough and share the solution with all of us.
I encountered the same problem and I've thought of a possible solution (though not tested it):
Use your background.html to store the content of the popup action and upon loading the popup, you fetch the content via the default messaging for chrome extensions.
When doing all kinds of other stuff, like XHR's or something, I think you should do that in background.html too, so the requests won't abort if you close and you can do something with the result. Then when a user re-opens the popup, he'll see the result of his previous action instead of the default screen.
Anyone tried something like did already?
As far as I know you can't persist a pop up menu but my workaround has been using a content script to append a menu on page load. After the menu is appended you can toggle the menu via messaging between the background script and the content script.
If you want to encapsulate the menu from the page it's deployed on you could wrap your menu in an iframe. This could add complexity to your project since you would have to deal with cross origin issues and permissions.
There is an alternative hack for this. You can make use of chrome local storage to store the metadata as needed. Upon restart you can read that metadata and render the desired content. You will also probably clear that metadata after you have completed performing the operations based on that.
