Here buttonClickedis internally mapped with the Java code.
When you click on button your buttonClicked(View view) method will be called.

You can register listener to your button like this as well in your code:

findViewById(R.id.your_btn).setOnClickListener(this);

Then your class can implement onClickListener interface.
You need to overrid onClick(View v) for this.

Now when you click on button your overided
onClick(View v) method will be called.

Create two different method to ScaleX and ScaleY then set those points in before you actually drew them.

[ShikhaTan]

x-low: 50 - 0 = 50
max-low: 1-0 = 1
newpointx = 50/1 = 50

I guess it doesn’t work! I believe the max/min that the original formula refers to is the min / max of the original points 50/100. With that hint you should be able to complete the assignment

3NT is not really used 100% in the real world – the cost of storage and processing is not like it was back in 1990 when every byte of data mattered!

The scale of the tables will also dictate the structure at times. If there are 5 billion records sitting in a table that and there are 400 hits per minute, you will definitely see different structures.

However, back to your specific question:

In your sql statement, the values inside the ON will be the same!

=> Users = every user, both buyer and seller,
=> so bidding user is just a subset of the users table

For java you should use this:

For Javascript you must explain clearly what you want to achieve and by what means.

We will help you with code if you prove us that you actually wrote some. Post the part that isn’t working and we will explain/fix it.

It is for a class assignment, the professor didn’t specify what type of cursor it needs to be, when I was googling for help I did notice the two different types.

The code I have so far does what you’re saying too doesn’t it?

FOR SELECT Emp_no, Project_no FROM Works_on
INNER JOIN Employee
ON Works_on.Emp_no = Employee.Emp_no
INNER JOIN Project
ON Works_on.Project_no = Project.project_no
WHERE Project_no = 'p1'

Except I probably should change the where statement since it’s supposed to go both ways.

The code you have written up is that just taking the data from the table into a temporary field? How would you then update the old values so that project p1 are moving to p2 and all of the employees working on project p2 are moving to project p1

Table is named ‘stats’ and field names are like in the first post. (Timestamp, Name, in, out). That’s what you mean right ? The names are not that important I’m sure if I’ll have the syntax I can fix it to work with my db. Thanks again for your effort.

[ShikhaTan]

Haven’t really worked with mysql so it might be really simple I just can’t come up with a reasonable syntax

If the file is owned by you, you should have permission to write into BUT nobody else. The CHMOD file should be 644.
PS : In your algorithm it’s write : ” Change the permissions on the file to allow writing by the user. “.

how much programming do you know?

do you understand structs? do you understand pointers? file input output? strings? number variables?binary? hexadecimal? RGB colouring system?

if you understand all of the above you have everything you need to be able to write to bitmap

next all you need to see is how a bitmap file is structured (look into wikipedia) , understand how the header part looks like, add teh header part and then add all the pixels and colours you need and you can read and write to a file as you wish

if you understand all of this you wont have any problems

there really isn’t anything else to it

a bmp has a header part which identifies its size, type details etc

and the source code part which is obviously the pixels you intend to write to it to create whatever picture or graphic, really it can be learned in hours

In any kind of learning it’s great to be sure that you have a good teacher (not a random guide-writing guy on the internet).

And one of the best possible teachers for C++ is the language’s creator – Bjarne Stroustrup.

There is a new edition of his introductory book Programming -- Principles and Practice Using C++ (Second Edition) available, and it looks like a great entry point.
It also includes all the new language features – if you’re new, it’s best to treat the language as a complete package, without dividing into old and new, and that’s just what Bjarne is doing in his publications.

Start with “Head First Java” book. Then read “Effective Java” book

Java is the second most used language according to:

http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html
Java is a good choice. That said if you want to learn advanced topics you should really search more specific, what do you want to learn more about, if you want to learn about Desktop gui applications then:

http://it-ebooks.info/book/399/

if you want to learn mobile programming, Java for android development is a good choice.

[ShikhaTan]

Just search on Google for Java tutorials or resources or whatever. If you want to learn something like a programming language on your own, you need a lot of self motivation. Even this forum probably has people who have asked this question before, and links to resources and ebooks and whatever. Best of luck to you friend.

For Ios you have to pay and use a virtual image of osx or have a mac. For android you have android studio and/or NDK.
