it wont work. he has a text file, not a binary one...
and your method doesn't take in account the space delimiters between the values in one line...
however, the idea of the struct can be a good memory representation, once the file is read, to load its content in memory

Overlooked "TEXT FILE"

Try this:
---------
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
int main(int argc, char* argv[])
{
using namespace std;
// Open the file.
ifstream fs("C:\\a.txt");
if (!fs)
{
cerr << "Couldn't open file!" << endl;
return 1;
}
// Read in the lines and sum them.
string line;
while ( getline(fs, line) ) // Get a line.
{
// Sum each number in this line.
int num;
int sum = 0;
istringstream iss(line);
while ( iss>>num )
{
sum += num;
}
// Output the result.
cout << "Total: " << sum << endl;
}
return 0;
}

For starters:
int n1, n2;
FILE *pFile = fopen(..., "rt");
while (! feof(pFile))
{
fscanf("%d %d", &n1, &n2);
}
fclose(pFile);

Here is a very basic solution:
<br />
void main()<br />
{<br />
vector<int> Col1, Col2;<br />
ifstream fin("mytext.txt");<br />
while (!fin.eof())<br />
{<br />
int c1, c2;<br />
fin >> c1 >> c2;<br />
Col1.push_back(c1);<br />
Col2.push_back(c2);<br />
if (fin.eof())<br />
{<br />
break;<br />
}<br />
}<br />
<br />
int Column1Total = accumulate(Col1.begin(), Col1.end(), 0, add<int>()); <br />
int Column2Total = accumulate(Col2.begin(), Col2.end(), 0, add<int>());<br />
}

Please can somebody help me. I am just not getting it.

Having you considered using the CButton::Create() method? What code do you have that is not working?

This is what I have done:
void CBudget::CreateRadioButtons()<br />
{<br />
CButton newRadio;<br />
CRect rect;<br />
<br />
#define IDD_NEWR1 0x1234<br />
<br />
rect.bottom=150;<br />
rect.top=100;<br />
rect.left=100;<br />
rect.right=250;<br />
<br />
newRadio.Create(_T("Home"), WS_CHILD | WS_VISIBLE | WS_TABSTOP | BS_RADIOBUTTON, rect, this, IDD_NEWR1);<br />
but nothing showsup. I have called
CreateRadioButtons() in OnInitDialog()

I think you should move the CButton newRadio; declaration to the class body. Make it as a data member of CBudget. Otherwise your control is deleted after finishing the CreateRadioButtons function.

Another solution is to put your controls in the dialog using Dialog editor, making them invisible. When you need to show them, just make visible. In this way is easier to define event handlers for your controls.

Ah yes! It worked. Thanks.
Now, if I create 3 buttons, how do set then as a group. i.e how do I use them? How do I get which radio button has been selected.

Use the WS_GROUP style for the first one.

Add Handler's for them in message map section
ON_BN_CLICKED(ID_RADBUTTON ,OnRadioClicked) // Defined ID_RADBUTTON
//in the header file
afx_msg void OnRadioClicked();
//and in the cpp file
void CCheck1Dlg::OnRadioClicked(){
//Some COde
}

The problem is I do now know how many will be needed. It dependes upon how many budget entries a user makes.

Can I not create another radio button using the same CButton object, newRadio?
Fortitudine Vinsinues!

Yes, but newRadio will need to be a pointer.

A CButton object is for one radio button. If you need more, define another CButton data member.
In case of variable number, you can define a dynamic collection of such objects. For instance, you can try CTypedPtrArray< CObArray, CButton * >.
You have to create new buttons with new CButton, then call Create, and then add to collection with Add. Do not forget to delete the unneded buttons with delete.

Oh no I just dont have the time to figure out that. I guess I use good'ol combo box or a list box instead!!
Thanks a lot for the help everybody. I will definitly try it out later, and maybe post an article;)

Move the line CButton newRadio to the header file Budget.h
What i think is that you are going to create these buttons dynamically and more than once. So it would be better for you to change the function definition to
CreateRadioButton(int,int,int,int);// Specifying where to place the buttons.

This object has function-level scope. It needs to be a member of the CBudget class.

If the utility will be spawning the console application, see here and here. Otherwise, you'll need to go this route.

Hello all,
By following article at http://www.codeproject.com/internet/rpcintro1.asp and http://www.codeproject.com/internet/rpcintro2.asp, I was able to have RPC feature in my application.
However, I realize that even I successfully call the RpcServerUseProtseqEp for the first time. I will have problem calling the same function, with same parameters at the second time, after I close all the RPC resource using RpcMgmtStopServerListening. I will get the following error result:
RpcServerUseProtseqEp failed. The endpoint is a duplicate. (1740)
The sequence of my RPC server is as follow, RpcServerUseProtseqEp-> RpcServerRegisterIf-> RpcServerListen (In another thread)-> RpcMgmtStopServerListening-> RpcServerUseProtseqEp (Opps! Fail at here)
Any idea on how I can restart the RPC service after I end it?
Thank you

AFAIK the interface used by the two types is all together different with very little similarities being shared between them.It would be easier for you to put your code again in console based application.
