Re: please suggest me some good pregram using datastructure.

Some suggestions:

create a fast XML-parser, with low memory usage
create a program that writes MIDI-files (you will tear your hair out)
Show the waveform of a wavefile
Create a program that parses an EML-file, including attachments
Create a simple interpreter. for example. one that can execute batch-files
Write a C-compiler
Create a RTF-editor

Satisfied?

Yes satisfied, may be this is tooooo advanced for me.
but I am gonna try it out..... Big Grin | :-D

may be i can create an XML parser with high memory usage, then I can optimise it.....

and other programs.....okey i will try.

EXIT_FAILURE, EXIT_SUCCESS

stdlib.h defines EXIT_FAILURE as 0 and EXIT_SUCCESS as 1... though convention is that these two are usually used the other way around - I'm just wondering why stdlib defines them like this... is convention wrong? Smile | :)

In both SDKs of Visual Studio 2008 and 2010 (also Window 7 RC SDK)

it's defined as

/* Definition of the argument values for the exit() function */

#define EXIT_SUCCESS    0
#define EXIT_FAILURE    1

How it differs in your SDK headers?

On my Mac, both gcc (Mac OS X, gcc-4.0.1) and VC++(Windows 7/VMWare Fusion, VC++ 9.0) define EXIT_SUCCESS as 0, EXIT_FAILURE as 1...

Hmm, I recall it being defined the other way around...

The reason I thought this is because I was returning EXIT_FAILURE / EXIT_SUCCESS from a function, but checking the result against TRUE / FALSE.

EXIT_FAILURE would always be considered true, and EXIT_SUCCESS considered false... I should have checked the actual definitions... Blush | :O

Capture Events Written to Application Log

Hi,

I am supposed to develop an application(yet to be done)which continuosly monitor the Application log in Windows 2003 and Windows 2008 servers (both seperately).

When ever an event is logged in the Application log corresponding event source, id and description is obtained and displayed in to the screen.

I have refferred MSDN and found that the notifyChangeEventLog() method will do this.

I have tried out a sample and was able to get event id alone, but not event source and event description.

Can some one please tell me how to obtain event description and source using c++ program.

Also please suggest me the best solution to develop this application.

Thanks in Advance

Reading .csv files

hello,

I want to read .csv files but the following code read many lines more than required.

std::ifstream DataStream(FileToRead);
istreambuf_iterator<char> iter(DataStream.rdbuf());
istreambuf_iterator<char> end_of_stream_iterator;

int NOOFCHAR =10;
char temp[255];
CString h ;
int ct =0;
while(!iter.equal(end_of_stream_iterator) )
{
vector<CString>v;

for(int i=0;i<FileObj.NumCols;i++)
{
DataStream.get(temp,NOOFCHAR,',');

DataStream.ignore(1,',');

h = temp;

v.push_back(h);
}
ct++;

DataStream.get(temp,NOOFCHAR,'\n');

iter++;
}

In the above code I should ct = 2331 but I get the valu of ct = 198520
what must be wrong . and why the program doesnt end at line no 2331

Where are you telling it to end at line 2331?

Have you used the debugger to step through the code to see if you agree with what it is considering a line?

why it's necessary to create iterator for a file buffer? you don't need to deal with internal buffer of a file. You can simply use other stream, string classes to get your task done. Just see a sample code below. it's plain and clear no? (Sorry it's not written myself. taken from some forums)

#include <iostream>
#include <iostream>
#include <sstream>
#include <fstream>
#include <vector>
#include <string>

using namespace std;

int main ()
{
    ifstream inFile ("csv.dat");
    string line;
    int linenum = 0;
    while (getline (inFile, line))
    {
        linenum++;
        cout << "\nLine #" << linenum << ":" << endl;
        istringstream linestream(line);
        string item;
        int itemnum = 0;
        while (getline (linestream, item, ','))
        {
            itemnum++;
            cout << "Item #" << itemnum << ": " << item << endl;
        }
    }

    return 0;
}

I want select a certain area from an image, and I kenw in cximage exits selection layer,I wonder if the pointer "pSelection" is can be used to point to part of the image,not the whole image.

and the function BYTE* selectionGetPointer(x,y)
Suppose I gave the start coordinates x,y of a area,
if the return value can be regared as the pointer which points to the beginning pixels of a selectiron area ??
