Well i haven`t known sql server before. So I build it using my own application. I am studying sql server now.
From indonesia, maybe a place where you have never imagine.
I`m doing a project for my degree, about implementation of datawarehouse at a company. Thanks for the help again. Maybe if i have another problem, i`ll contact you

Abstract
Data classification is an important problem in data mining. The traditional classification algorithms based on decision trees have been widely used due to their fast model construction and good model understandability. However, the existing decision tree algorithms need to recursively partition dataset into subsets according to some splitting criteria i.e. they still have to repeatedly compute the records belonging to a node (called F-sets) and then compute the splits for the node. For large data sets, this requires multiple passes of original dataset and therefore is often infeasible in many applications. In this paper we present a new approach to constructing decision trees using pre-computed data cube. We use statistics trees to compute the data cube and then build a decision tree on top of it. Mining on aggregated data stored in data cube will be much more efficient than directly mining on flat data files or relational databases. Since data cube server is usually a required component in an analytical system for answering OLAP queries, we essentially provide “free” classification by eliminating the dominant I/O overhead of scanning the massive original data set. Our new algorithm generates trees of the same prediction accuracy as existing decision tree algorithms such as SPRINT and RainForest but improves performance significantly. In this paper we also give a system architecture that integrates DBMS, OLAP, and data mining seamlessly.

hi
I have an MFC MDI application, in which i carry out an process and at the end open an log file.
This process involves quite a lot of time. During this process, i want to implement a progress bar, showing the status of the process. How do i do tht.
Can someone, please help me on this. I thank in advance.
cheers

You can have a simple dialog loaded from the MDI - It would be only displaying the progress bar. The value of the progress bar can be set from the parent MDI.

I tried that. But that doesn't happen in parallel. Only after the progress completes, my process of loading the file starts.

Hi ,
I want to add a menu to dialog bar, not dialog box. For dialog bar, the menu property is disabled.Is there a way to to this?
My Main aim is to have a seperate menu for MDIChild window-form view. So I intend to attach a menu to dailobar and add this dialog bar to form view. I want to use a dialog bar instead of a dialog here.The problem with dialog box is when the focus is on the view, the dialog menu appears to be disabled i.e grayed and vice versa. Or cau you please suggest how to make the dailog appear to be eanbled irrespective of focus
Thanks

Hi!
Can somebody help me out?
I get a syntax error, when I try to compile this code.
The syntax error indicates,that I'm missing something before the else if(riid==IID_IX).
Can somebody help me out? Thanks!
if (riid == IID_IUnknown)
*ppvObject = static_cast<iunknown*>
else if(riid == IID_IX)
*ppvObject = static_cast<ix*>(this);
else if(riid == IID_IY)
*ppvObject = static_cast<iy*>(this);
else
{
ppvObject = NULL;
hr = E_NOINTERFACE;
|
|

|

You're missing the argument to static_cast. Btw, the code looks very suspect. Why do you have a nested if when all you really need to do (imho) is:
if ((riid == IID_IUnknown) ||
(riid == IID_IX) ||
(riid == IID_IY))
*ppvObject = static_cast(this);
else {
ppvObject = NULL;
hr = E_NOINTERFACE;
...
}

I think you miss ";" at the end of the line " *ppvObject = static_cast ",do you?

From MSDN, it says
GetDefaultPrinter is included in Windows 2000 or later.
I am using WIndows XP, and look at the windows.h and winspool.h, I could find the declaration of this function.
In fact I try to run the following sample code provided by MSDN at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/GDIPlus/UsingGDIPlus/Printing/SendingGDIPlusOutputtoaPrinter.asp
But it failed by saying the GetDefaultPrinter undefined.
Can anyone help me to fix this problem? Becasue I would like bypass the Printer Diolog using GetDefaultPrinter.
Thanks a lot

I would like to put some sort of tree structure in an internet explorer side bar but I haven't been able to merge my bar with any of the many types of trees I have learned about these past couple of weeks. Something like the view->explorer bar->folders would be optimal. I hope someone can at least point me in the right direction. 
Thanks in advance,
Biggie.

I use the function
int ExtEscape(
HDC hdc,
int nEscape,
int cbInput,
LPCSTR lpszInData,
in cbOutput,
LPSTR lpszOutData
);
at my program.Because of my poor English,I couldn't understand the function's introduction at Microsoft Windows CE.NET Help.Could you give me a introduction about the function and the use of it in detail?
Thanks!

The documentation in the Platform SDK covers this in detail, but in brief this function allows you to access driver-specific functions that are not exposed by the Windows GDI. The specific device is passed to the function using its handle, hdc. The device driver function is specified by nEscape, while lpszInData is a pointer to whatever data is required as input for the function. The cbInput parameter specifies the size of the structure indicated by lpszInData in bytes. Similarly, the lpszOutData parameter is a pointer to the structure where you want the results to be stored, and cbOutput contains the size, in bytes, of this structure. ExtEscape returns a positive value if the call is successful, and 0 if the requested function doesn't exist. A negative return value indicates an error. Several predefined values exist for nEscape, primarily related to printers, but other than these you are free to specify any value supported by the target driver.

Hi
I have just started learning C++ GUI programming using Visual C++ (I'm using VC++ 6), and I have two questions regarding it:
1. Let's say I create a dilog-based project, and I put some things (buttons, lists, etc.). The problem is, when the user maximizes the the dialog, the button placements are not automatically modified, leaving a large part of the maximized window blank. Is there a way to automatically reposition ALL the things inside the dialog when the user maximizes the window (or resizes the window, for that matter)? Or do I need to manually recalculate the correct positions and sizes for all the things and apply them one by one?
2.Is there a tutorial/website that explains how I can create other GUIs beside the document/view or dialog-based GUIs that Visual C++ provides (e.g. skin-based GUI, GUI's with shape other than simple rectangle, etc.)?
Thanks!

MFC doesn't come with a layout manager like Java. However, see this[^] and this[^] CP section for answers.

I just want to know the initializtion of the parameter lpCmdLine. Could you tell me how and where to find it?
thanks!

lpCmdLine is passed into your program from CRT initialization. The CRT just calls GetCommandLine.

I'm going to patent thought. I have yet to see any prior art.
