Sorry if the question isn't so clear. My system has a many to many relationship with a 'groups' table(a user might be subscribed to many groups and a group might have many subscribers), since I know managing all the content(post with lots of comments, likes, dislikes, etc) in MySQL is more complicated, I thought HBase would be a good alternative to save this data because of its BigTable design that suits the twitter-style feed I want to have. The approach I think of is having my intremediate many-to-many relationship table to serve as a list of unique keys I could use in HBase, this way I can extract data like 'how many subscribes in a group' more easely in MySQL and HBase would only handle the delivery of data. Since I have no experience on BigData or HBase, I would like to know what would be your approach. Thanks for answering by the way.

It might be the type of DateTime you are or aren´t specifying(ie, DateTime.LongTime), can you post some of your code?

Member 8437747 14-Jul-13 22:56pm View

Hahaha I wrote that because in some of my questions, when I wrote code in that simplified way people often asked me for the real code.

Sorry if dont catch up that fast Im young and I only have a couple days in c++.

I really appreciate your help and admire your experience.

If I have the two classes on separate header files, using the keyword 'class'

as in: "void printClassA_variable(class A *myObject);" will be usefull?

or what should I write so both know of their existence?

Member 8437747 14-Jul-13 18:20pm View

This is a very nice and functional solution, you should try it.

Member 8437747 16-Aug-12 14:32pm View

Well I consider writing this method into Account and overload it would be the best option, if you want to do a general class that abstract you should study more about OOP and abstraction.

Enjoy your time here in this page and dont doubt in sharing any knoledge, we are here to help each other.

thanks for the help and your effort just one little question, since I havent get to the input stream in the c++ books I´ve read could you tell whats the str for? and supposing I get right I need to make a couple of if's, could I used this mechanism with the up, down, right, left arrows?
Ill accept your answer friend

Could you give me an example using cin.get(). This project is a little excersise program, cause Im new to C++. And what is the best method to use sleep() in my code.

Member 8437747 14-Aug-12 16:17pm View

Thanks for the help, although using sleep wasnt the problem (it was the way changed the Y variable) it was an usefull help by minimizing the speed of the object

Member 8437747 20-Apr-12 21:52pm View

well it would if people make good and useful comments, people are here to make questions and receive answers(usefull answers)

If you han´t any usefull comment please, please shut up and stop waisting my time.

thanks

Its simple my friend:

I have a class: Player.cs
Since I dont want the class to create a new axWindowsMedia object I have this constructor:

public AxWMPLib.AxWindowsMediaPlayer player;

class Player
{
public Player(AxWMPLib.AxWindowsMediaPlaye theObject)
{
this.player = mediaPlayer; //This is the error line
}
}

The error occurs when I try to make a instance of the class:

Player p = new Player(axWindowsMediaPlayer); //line 56

What do I have to do to use the property object declared in my class instead of creating a new one inside the class?

Opassw0ord is a varible, is used to represent the old user password.
I´m using an access database.

Member 8437747 20-Jan-12 18:36pm View

OK, it helped a bit, Im over it already but I had an error sayng some parameters have not been filled with essential info, I have the code like this:
string command = ("UPDATE Users SET [@Id] = "+password+", [@User] = "+user+" WHERE [@Id] = "+Opassword);

but all the specified parameters are already there, whats rong?

Member 8437747 18-Jan-12 19:07pm View

I get that the Id parameter hasnt a predetermined value

Member 8437747 18-Jan-12 18:42pm View

the WHERE Id = ? command refers to the old Id how would the syntax be?

Member 8437747 18-Jan-12 18:41pm View

Id is a field to may I use the "[]" on Id to?
I forget the last field WHERE Id = ? is the olda Id

Member 8437747 13-Jan-12 21:02pm View

thanks that worked perfectly
Just another little cuestion how may I or what type of loop can I make so I can put multiselect true on the OpenFileDialog box cause with the foreach I used befor it only copies one file?

Member 8437747 6-Jan-12 18:57pm View

No, Im trying to copy files selected by the user (IN THIS CASE THE MyMusic folder) in any folder or path and coppy them to the app.exe location where I have 2 folders called "Music" , the other is called "Video"; I have a button in my app that should copy the files selected into the music or videos file, but I get the Directory not found:

Im using the Path.GetDirectoryName to find the executable pathh of the app
and then I include the \\Music path but I still get the exception

The path does exist so whats the problem?
Thanks

Member 8437747 3-Jan-12 19:21pm View

Thanks this method works but I still get the exception, the program is installed on a USB so its diffiult to find or locate the path so I only insert @"" in my other to reffer to the path where my program is located the problem is if only put @"" it wont copy the files and if I put @"Mydoc\"
I´ll get the exception

Member 8437747 30-Nov-11 20:53pm View

sorry about the last comment I wanted to ask how may I do that?

Member 8437747 30-Nov-11 20:52pm View

Thank you it has been helpful for finding the device insertion/removal but about the info I would Like to obtain the product ID of the usb, do you know how could
