well i thought that too but data base = mysql ? 
but i dont thing so that the video clubs that got a application
with all the renters , uses mysql
(on C++ i tried to crate Data base project and it ask my for dns login name pass etc :S)
I thought to work with edit text fuctions
(so in each line the first 10 letters/spaces will be for the ID
next 20 for Name next 20 for Lname next 10 for BirthDate)
(so with a buffer gonna read first 10 letters in each line
and when the ID is the same value with the value the User
have given it will collect the other 3 information
Just my University teacher told me it would be easy doing
it with Data structures

It is very difficult to understand you, can you please make a little effort on your spelling ?

As far as I know, SQL is only a language to access your database in an uniform way. For mySQL, I don't know what it is exactly but it is certainly not the only database type that exists.

I don't understand what you are trying to say. Anyway, I'm almost sure that video clubs systems use a database to store their customer data. For me, that seems the most adequate thing to do.

I'm not experienced with databases but there are several ways to do it (I thin you tried through the wizard, whihc I don't really like). If you make a search on this website, you'll find a lot of usefull classes to help you.

Yes, I know what you want to do but it will be much more efficient to do it using database (I you don't need to to write all the stuff to read the files, parsing and searching... everything is handled by the database classes). Of course, you need to spend a little bit of time to understand how it works.

You can use a database and still use data structures to manage your data.

thx i will try that ( i had search info about Data structures and didnt finding something useful ) i will search about Data Bases

I think you have understand me and yes i dont like to make the application as i said (I know how to edit text etc , but i dont
know how to use databases / data structures , so i want to try
make this project with databases and get some skill on this type
of projects.

yes, mySQL can be used to do this, but I'm no expert.
but i dont thing so that the video clubs that got a application

NO!
use a struct or a class it will be so much simpler in the long run.
since it's for a school project, I will suggest you keep away from mySQL, and simply use list or vector to keep the data; I'm not sure you will be able to manage sql stuff.

well i know how to use Mysql (create tables ,Primary keys ,foreign keys etc , INSERT INTO xxx VALUES(); etc )
but i dont know how i can connect Mysql in my program
using list + vector to keep the data this will be a permenatly save?
I want my program to create a data base (i think its a data base) with the 4 member variables
And i just cant understand (if the suggestions you give me is for that) where the data will been saved :S (so i can callback)

hm my teacher said to use class (he said something that the type of this class dont have fuction ? so only the values of the "data" ?)
(i cant explain well in english :P)

Entry e;
e.ID = 241;
e.name = "John";
e.last_name = "Papadopoulos";
e.birth_data = "19/01/1980";
EntryVector.push_back(e);

so when i close the application these values will be saved somewhere in my hard disk ? (same folder with the application?)
And when i will run agian the application and give id 241 it will be show me this register? ( ID=241 , Name = John , Lname = Papadopoulos Birthdate = "19/01/1980"

no, but I think that part of your job to do this !!
Go back to your notes, books and lectures, and read a little bit, I'm pretty certain this was all covered somewhere.

well i have not notes i am on the third year in university (I was idiot i didnt take part on the lectures in the first 1.5 year )
So i didnt take part on course Data structures.
Databases we do on Mysql only :S
I did take part on Software Techologies ( and made a exam-exersice Program that plays mp3 and download mp3 from server (+chat ? ) took 10/10 degree \o/ )
But i have Big holes on C++ ( i dont say i know C++ :P )
Thats a bit of my life ! (trash text !:P)
Now i look in my Data structures book and find things that i cant connect with my work (Binary Trees etc ):/
My teacher on that course dont know Programming code (she is intresting on the UI of the application) (so no notes about code from her
(and about code programming i had ask my last year teacher who knows much )

A data structures teacher that doesn't know programming code. That's reassuring.

Not unless you employed some sort of file I/O.

hm yes and which is the way to do that ?
(allready start searching about Data bases class on this site )

STL has plenty of options, like istream/ostream and ifstream/ofstream. I'm an STL novice so I'm sure it has more.
MFC offers the CFile and CStdioFile classes.
With C you can use FILE*.
The Windows SDK has CreateFile(), ReadFile(), etc.

Hi,
I intend to integrate the functionality of two dlls into one by means of merging the code. I'm adopting the following steps.
1) Create a master framework for the merged entity say dll A.
2) Include all the files that are distinct for the two dlls(B & C) into the project created for dll A.
3) For all the files that are same in dll B and C, include a single file into the merged entity and into that file put all the functions that are distinct in the file under B and C.
I think this should suffice. Please correct if there is something to be done
The problem comes for functions that are same in the common file.
Say in dll B We have a function like
class B : function()
{
}
Say in dll C We have a function like
class C : function()
{
}
Here the two different functions need to be merged into a single function under a class name.
Now my question is how does the merged entity break into two workflows similar to the functional behavior in the previous separate dlls? What kind of conditional can be put for identifying the different behaviors?
Thanks

hi guys,
I come with a small question.
I want to add, as a resource, a small midi file to my application and play it continuosly during program execution. So that when the application is open the sound is played...and it stops when the app is closed.
Time ago i founded a code snippet which uses directx8 but i don't why it worked only on my pc...but not on other people pc.
Thanx in advance

Hi!
I'm pretty new to C++, I read some big books about it and got pretty much into the basic thinking in C++. Unfortunately I did not learn how to simply write a tool with a basic windows XP interface containing one button, which executes an action when I hit it.
To be more specific, I want to code a tool for XP that got one button and when I hit this button it will send a telnet.
Can anyone help me plz? Cause I just don't know the very simple basics for writing a very simple tool with GUI.
Thanks a lot!
Phong

Use AppWizard to create a dialog-based application. Add a button to the dialog template. Handle the BN_CLICKED message for that button.

Not sure "telnet" would qualify as "simple"

if MDI or SDI app then use CScrollView it will handle
every thing for you.
If you yourself wana do do you yourself have to handle
CWnd::OnHScroll
in that function check how much to scroll
and then do the drawing according to that.
will help

A list box is configured with both horizontal and vertical scroll. A string is inserted that is greater in width than the display area, but the horizontal scroll won't allow scrolling to the end of the string. What additional functions need to be called to enable the horizontal scrolling? Thanks.

How about setting the control's horizontal extent?

Using the SetColumnWidth? I tried this, but it didn't change anything.
CListBox *lbptr=(CListBox *) GetDlgItem (IDC_LIST_TAB1_IDW );
CString s;
POSITION pos = fileDlg.GetStartPosition();
while (pos)
{
s = fileDlg.GetNextPathName(pos);
lbptr->AddString(s);
}
lbptr->SetColumnWidth(1000);
lbptr->UpdateData();

No. Use SetHorizontalExtent().
jon_fallon wrote: lbptr->UpdateData();
Totally unnecessary.
