muu | Miscellaneous Useful Utilities for C++

Actually, I'm not a programmer but I have an assignment that I should finish. I have asked people around me and look at other questions, but I still can't implement it in my work. Well, I'm gonna make a program that can calculate a column. So I calculate it on the first activity, then pass the result to another activity. In the second activity, I want to show a Scatter Diagram, using MPAndroid Chart. I have try my codes with a random numbers, and it work. But when I pass the data, the app is crash, and here is my logcat :

I'm confused about how to use ecto in phoenix.

My schemas are:

I'm trying to program a formal system that has these rules:

• You start with the string "MI" (which is the text of the label at the beginning)

There are four rules of inference : 1) If the last character of the string is "I", you can add a "U" to the string (ex: MI --> MIU)

2) Being x a sequence of letters, Mx can be replaced with Mxx (ex: MIU --> MIUIU)

3) If the string contains "III", you can replace "III" with "U" (ex: MUIII --> MUU)

4) If the string contains "UU", you can delete the "UU" part (ex: MIIUU --> MII)

In my project, rule 1 corresponds to button1, rule 2 to button2, rule 3 to button3, rule 4 to button 4

Also, since a user may end up in a infinite loop sometimes (ex: if you get to "MIU", from then on you can only use rule 2 and get "MIUIU" and so on) I added a "clear" button. I want the clear button to just turn the Label.text into "MI" so the user can just go back to the starting point and retry

The point is, for some reason when I press the "clear" button the Label.text does not turn into "MI" as I would want it to, but it turns into "MIU" instead!

What am I missing?

PS: I know this might is probably something extremely easy that I'm stuck on, but I don't have much programming experience

This is my code: import UIKit

I try to process XML nodes which may have many data in attributes. I'd like to get list of attributes, but can't figure out, how to achieve it with XML::LibXML::Reader?

With attributeCount I can get count of attributes and the with getAttributeNo iterate over them, but this gives me just values, not attribute names.

I hoped to see something like getAttributes, but there is no such method for attributes

Sample code:

So I've got a simple task to do. There are 3 classes derived from one base class. They're quite simple and will be provided below. What I need to do is create a new class called PolymorphicAnimal, that'll be able to behave just as any other animal derived from the Animal base class. To be exact, all they need to do is display the right text after method SoundOff is called. I'm guessing I need to use dynamic_cast here. My question is, what's the right syntax for using dynamic_cast as an if statement, and do all the derived classes need to have at least one virtual method as well?

I'm trying to set in the parameter of the report two values if I set values in parameter @Hakemuksen tyyppi (Unknown + some other value) it gives error -

An error has occurred during report processing. (rsProcessingAborted) Query execution failed for dataset 'Table_1'. (rsErrorExecutingCommand) The function expects a tuple expression for the 2 argument. A tuple set expression was used.

I am going to recognize few imageTargets and I would like to play sound with onClick(button). This button is on canvas and it is always on top during the app lifetime. So You can see it always. Behind this button You can see camera view and recognize markers.

F.e I have two markers: Dog and Cow. Dog has assigned audio - bark. Cow has assigned audio - muu.

When I recognize Cow -> click the button and it should give me muu sound, but when I recognize Dog, the same button, when clicked should give me bark sound. Here is a problem. I cannot resolve it. I think I should write a script for this button to play sound onClick for appropriate marker, but I do not know how to tell button that now I can see Cow and another time I can see Dog.

I made a script which plays sound when image is recognized, but I would like to do it with button.

If something is not clear enough - let me know and I will write it better or again.

So far in my "Default trackable event handler" it’s worth it:
