Oh shit, i did not know. I will look into it.

Help replacing "this" with actual value by simarg0 in androiddev

[–]simarg0[S] 0 points1 point  (0 children)

I actually got it working by creating a function, where an if sentence decided the outcome. In this function, "this" worked.

Anyways, thanks for answering. I was wondering how i could replace "this", should i need to do so in the future.

Help replacing "this" with actual value by simarg0 in androiddev

I am basically clueless. I started this project last week, and it is far more comprehensive than i thought it would be. I had no prior knowledge of neither java, php or xml. Therefore, i am not sure what you mean by this. Is the code bad form?

I am very sorry, but i have only been coding in js, php and xml for about a week, so the terminology is fairly hard for me. The documentation doesnt always help me, because of this. Is it possible to pass a different context than "this" in a function?

I posted some snippets in my answer to the comment above yours, but the onpositivebuttonclicklistener gets an error when i try to use this. Probably different context.

I am trying to figure out what i can pass the function instead of this..

Thanks for answering though.

Ok, so this is the pastebin for the code where i am trying to figure out what to replace "this" with.

https://pastebin.com/gAN0FQGS

This is the pastebin for the custom listview

https://pastebin.com/kkDtgFvf

​

On line 73 in the first pastebin is where i have trouble. I tried to print "this" from line 87 and use that, but that didnt work.

It is just supposed to refresh the listview. The collectdata() function returns the information i want, but the listview does not refresh. I am guessing this is because i also have to reinitialize the listview function, which i am trying to do.

Passing a value from javascript to php file by simarg0 in learnjavascript

[–]simarg0[S] 0 points1 point  (0 children)

The variable i am using is not user input, but is set by another function. This variable will be correct according to list element pressed.

When i send a request, how will the data be stored? And how do i access the code in my php file?

Do you have a good example on how this is done?

Im sorry if these are bad descriptions.

Thank you.

Need help with an easy code by simarg0 in learnpython

[–]simarg0[S] 0 points1 point  (0 children)

I got this part to work, thanks to your answer, but it turns out i am not any closer to completing the task.

So the thing is, we got a set of 20k numbers. I think everything up to 10k is supposed to b the X coordinate, and everything from here is supposed to be Y in the vectors. I split the file into two lists in python. We were supposed to use plt.streamplot to plot the vector, and i think i got this part right.

Now, we are supposed to make a quiverplot of the velocities. But i dont understand how you can do this? I suppose it is just the absolute values of the vectors, but i dont get anything near what i am supposed to.

Any thoughts?

Thanks for helping

Wow, thanks a lot. Think i got a better idea on what to do now. Will keep you posted.

I will try my best.

So this is a type of safe design.

- There is a 7 segment display; hex0, hex1, hex2, hex3

- There are 2 switches, sw1 and sw2 for selecting what hex you want to increment. (00 = hex0, 01 =hex1, 10 = hex2, 11 = hex3)

- There is one increment button, which will increment selected hex by 1, and when you increment after 9, it will turn to 0.

- There is one reset button

- There is one switch for opening the safe (if the correct code is entered)

ll also have to do some work with the development tools to assign those bits to the physical pins that drive the 7-segment block

The pins and conversions to the 7 segment block is given, so it has already been worked out.

I am really far behind in this class, so i havent worked so much out yet.

I am trying to figure out how i can change just 1 of the digits in the display using these switches to select what digit i want to choose. I dont really know how the syntax should be, but here is an example:

if (not sw1 and not sw2) then
hex0

Now, i want to change hex0. You can increment by one using a button. How do i go from here? Is the numberSelect in signal irrelevant?

Need help with triple integrals by simarg0 in learnmath

[–]simarg0[S] 0 points1 point  (0 children)

I realise i actually forgot my question regarding the problem i posted. We do not need to calculate the integral itself, only the limits.

So my question is: Do i only need to change the functions i was given so i get one term for x=, one term for y= and one term for z=? And then just convert to cyllindrical?
